Roofing Shingle Granule Loss
When a Florida Roof reaches the end of its life, the ceramic granules on the roof shingles come off more readily as the asphalt that holds them in place begins to deteriorate. Watch for granules in your gutters washing out onto your lawn, or the roof turn dark as the asphalt is exposed. Asphalt Roofing Shingles may begin to curl when asphalt breaks down allowing water to penetrate the core of the roof shingle Read More »
Gloeocapsa magma is a species of cyanobacteria. Cyanobacteria are an ancient line of photosynthesizing bacteria, which photolyze water generating oxygen gass. Ancient cyanobacteria were ancestral to the chloroplasts of all plants on earth. Gloeocapsa magma has gained notoriety in the Southeastern U.S. which is quickly spreading throughout the Midwest. This particular type of cyanobacteria is responsible for creating the unattractive black roof stains and/or streaks commonly noticed by many. The bacteria accumulate over time; this accumulation begins to show the problematic black stains as the cyanobacteria develop their dark and hard UV-protective outer coating.
The main reasons for the rapid spread and noticeability of these cyanobacteria are thought to be:
1. Rising humidity and temperatures combined with more and more bacteria spores promotes their spread with these favorable conditions.
2. Fiberglass shingles (the most commonly seen amongst today's residential homes) have been being made with limestone as a filler (in the asphalt). These shingles hold moisture and organic "bacteria food" material longer (especially on the North-side in the Midwest) than the paper/asphalt/ceramic shingles of 20+ years ago. Additionally, these particular algae enjoy the limestone as a food source.
Once the bacteria have become noticeable, the stains will continue to worsen year to year. There is debate over the actual harmfulness of this particular bacteria to roofs, as there is little supportive scientific research. However, most "experts" within the subject area conclude the bacteria to be harmful, if left untreated, as the growth holds moisture within shingles causing premature aging, rotting, and/or granule loss
Gloeocapsa Magma is an airborne algae so it can land on any Tampa Florida area roof with no rhyme or reason, though it does seem to be more prominent in areas of Tampa, Florida holding a lot of trees. Once the roof algae Gloeocapsa Magma lands on the roof, it will have to be killed and removed properly or it will continue to spread.
The Gloeocapsa Magma will never get better or just go away on its own. The Gloeocapsa Magma algae begins feeding on the nutrients in the shingles.
As it rains the Gloeocapsa Magma spreads down the roof causing black streaks. If not taken care of Gloeocapsa Magma will take over the entire roof in a few short years turning the whole roof black. Besides looking very unsightly and diminishing any home’s curb appeal and value, what other damage can Gloeocapsa Magma roof algae do? When roof algae are not taken care of they stop the shingles from reflecting heat from the sun’s UV rays. When this happens it can affect your Tampa home’s heating and cooling costs without you even realizing it. Also because the shingles cannot reflect heat they start to diminish prematurely. Signs of wear are curled corners, wavy or humped shingles, broke or loose shingles, and an excess of shingle granules appearing in your gutters just to name a few.
Most Tampa Florida homeowners associations become concerned when the first unsightly black streaks of Gloeocapsa Magma begin to appear long before permanent damage is done. It’s at this point that most homeowner associations will call a roofing contractor and in my opinion it’s the point where homeowners associations are steered in the wrong direction.

Chemical maintenance systems for residential roofing materials
This invention discloses weatherable elastomeric and thermoplastic composite polymer films incorporating organometallic complexes for protection of exterior surfaces against the growth of dark colored algae. The process involves the surface reaction of water soluble polyvalent metallic salts with surfactants at reduced surface tension in the presence of film forming emulsion polymers. The lipophilic organometallic reaction products thus formed are encapsulated by polymer films with demonstrated exterior weathering durability in roof mastics and architectural coatings. By virtue of their vapor transmission, adhesion and elastic properties, the composite polymer films incorporating compatible algicidal organometallics extend both the life and appearance of exterior substrates.

BACKGROUND OF INVENTION
1. Field of invention
This invention relates to an improved chemical system for the enhancement and maintenance of cementaceous and composite asphalt building materials.
2. Description of the Prior Art
Cement tile and asphalt shingles have historically dominated the residential roofing market. Despite their success, the unattractive discoloration encountered throughout the United States and Canada particularly in moist temperate climates is becoming increasingly unacceptable. While the approach among respective manufacturers differ, the consensus in the cement tile industry has deferred the problem to the after market roof cleaning industry which has flourished in providing the routine service required to maintain appearance. High pressure water systems incorporating chlorine bleach are typically used. In warm humid climates typical in the Gulf States the service is required annually. Roof painting where permitted can postpone reoccurrence approximately two fold. In contrast, the asphalt shingle industry cautions against the use of high pressure washing systems as the process may remove granules which will shorten roof life. A gentle application of dilute aqueous chlorine bleach and trisodium phosphate from a ladder or walkboards is suggested by the Asphalt Roofing Manufacturers Association to avoid roof damage. The effectiveness of such cleaning is only temporary and there is little evidence of successful practitioners serving the residential asphalt shingle after-market. However, manufacturers offer several types of algae resistant products which have met with limited success.
The state-of-the-art technology for algae resistant asphalt shingles centers on a source of microbicide which can be released as a result of mechanical and/or chemical weathering. Of commercial significance, are shingles incorporating a percentage of zinc metal or zinc oxide coated granules as the inhibitor source. A second generation incorporating copper oxide as an inhibitor source of relatively higher toxicity has recently been introduced. The release of soluble metallic salts from these sources is typically via adsorption of carbon and sulfur dioxides in presence of moisture yielding acidic reactants. The residence time of soluble metal salts released from these products can be quite limited being readily removed by rain. However, slow release of inhibitor from these relatively inert sources is projected to continue over extended periods of time. Clearly, environmental conditions as they effect release and residence time on roof surface are major variables in this mechanism of inhibition. The effectiveness of the technology can only be improved with increased quantities of source material exhibiting higher levels of toxicity to counteract the transient nature of the active chemical inhibitors.
The present industry approach appears well founded on the observed inhibition which develops on the trailing surfaces below metal vents and stand pipes installed with roofing systems. While this potential source of tin, copper and zinc microbicide in the form of soluble metal salts is obvious, the mechanism by which inhibition is established may not be. A priori, released microbicide from any source must have a finite residence time in order to be effective. For this purpose, the exchange and chelation of polyvalent metallic ions with organic and inorganic receptor sites that develop on weathered asphalt and granule surfaces is well documented. Carboxylic acid end groups represent the highest oxidation state of asphalt surface while hydrous oxide surface functionality results from granule weathering. As electron donor sites, both interact with polyvalent metal cations to increase their residence time on weathered roof surfaces. Uncontrolled early release of such inhibitors contributes both to their fugitive nature and the substantial chemical inefficiencies inherent in the present state-of-the-art. Further compromises result from the complexities of asphalt shingle manufacture involving distribution and adhesion by partial embedment as the only means of securing granule inhibitor sources.
OBJECTS OF THE INVENTION
It is an object of the present invention to provide an improved chemical treatment system to inhibit algae discoloration which occurs on cement tile and composite asphalt roofing products.
It is a further object of the present invention to provide a durable transparent chemical system which confers luster with out altering esthetic appearance and retains a level of effectiveness consistent with the life of roof surface.
It is a still further object of the present invention to provide a predetermined controlled level of active chemicals securely bound and uniformly distributed over the entire exposed area of the roof assuring optimum effectiveness against discoloration.
It is another object of the present invention to provide a simple and economical process for the application of the improved chemical treatment system which can be used to enhance after market maintenance procedures and alternatively be incorporated in plant manufacture or field installation of cement tiles or asphalt shingles. These and other objects and advantages of the present invention will become more apparent to those skilled in the art when the instant disclosure is read in conjunction with the accompanying examples.
SUMMARY OF THE INVENTION
The above objects have been achieved in the process of the present invention by utilizing a weatherable water-borne resin in combination with wetting agents which confer positive spreading coefficients for effective uniform thin film coverage over the entire surface area of the roofing product. Incorporation of polyvalent metallic salts can be accomplished by concurrent premixing of compatible aqueous systems for combined application with resin or separate sequential treatment. On setting, the polyvalent metallic cations become bonded by organic ligands with the desired uniform distribution and intimate contact over the entire surface area susceptible to algae growth. The chemical treatment system inhibits algae discoloration of both asphalt shingles and cement tile and needs only to be applied to exposed surfaces given the true autotrophic nature of the predominant species encountered.
The transparent water-borne resins used in the system may suitably be any of the water-borne resins including those engineered for optimum adhesion and weatherability as single-ply membranes for built-up roofing application. Among the commercially more cost effective, vinyl polymers of acrylate esters and their copolymers with styrene, vinyl acetates and urethanes have gained prominence in built-up roofing applications by virtue of excellent weathering, adhesion and elastic properties. Emulsion systems formulated with thermoplastic, cationic exchange and chelating resins can also be used to secure the polyvalent metallic cations. Copolymer polyacrylate resin products of anionic polymerization are particularly suitable; alone or in combination with other organic ligands.
Employed in conjunction with the water-borne resin is sufficient wetting agent, based upon surface tension required, to achieve positive spreading on the substrate surface. A wide variety of ionic and nonionic wetting agents are available for this purpose. The preferred wetting agents are high performance alkyl and alkyl ester sulfonates, which provide excellent system compatibility. The preferred water-borne resins and wetting agents comprise anionic organic ligands which serve to secure the polyvalent metallic cations in the form of unique chelates and salts with general microbicide activity and excellent chemical stability. The preferred microbicides are comprised of water soluble salts of copper, tin and zinc which also confer the desired system compatibility and durability.
DETAILED DESCRIPTION OF THE INVENTION
The method of the present invention is suitable for treating exterior residential roofing products which support the growth of unsightly dark colored algae. Representative products include the popular composite asphalt shingles and cement tiles which typically contain carbonate nutrients for the prevalent gloeocapsa algae. It is beneficial to clean or otherwise restore the esthetic appeal of roof surfaces prior to application of the chemical inhibitor system. As a special feature of the present invention, surface active agents are incorporated to overcome the resistance to wetting and rewetting characteristic of roofing surfaces. The enhanced performance of bleaching and/or cleaning processes through the use of wetting agents is readily apparent in terms of the uniformity of chemical absorption achieved. The incorporation of optimum surface specific wetting agent clearly advances state-of-the-art and is instrumental to chemical effectiveness and efficiency of roof cleaning as well as application of inhibitor system with uniform distribution and ultimate adhesion.
The inhibitor system of the present invention is composed of polyvalent metallic salts and chelates with the organic ligands of wetting agents and water borne-resins. The system is produced on the roofing surface through interaction of inorganic water soluble polyvalent metallic salts and formulated organic water-borne resins and wetting agents. The soluble polyvalent inhibitor salts become encapsulated as the resin sets through interaction in binding dissociation equilibria. Displacement of monovalent resin and surfactant cations by polyvalent metallic inhibitor cations is solubility driven by the precipitation of insoluble polyvalent salts and chelates. The monovalent cation by-product salts are eventually leached from the inhibitor film system during subsequent weather exposure. Uniform deposition accomplished with the use of wetting agent permits the ultimate system stability and versatility. The durability of the inhibitor system derives from the inherent bonding nature of film forming resin and the compatibility of organometalic inhibitor salts and chelates formed upon co-application of the chemical system. Substrate surface as the point of microbial growth can be uniformly protected with effective composition and concentration of inhibitors. The physical and chemical stability to ultraviolet light/weathering as well as the level of toxicity for a range of ion pairs is well documented as basis for selection. Most significantly, the novel polyvalent metallic salts and chelates of organic ligands produced by exchange exhibit greater affinity toward the organisms responsible for discoloration owing to their lipophilic nature.
In addition to uniform application of the inhibitor system, stiochometry is important for optimum chemical efficiency. For this purpose, an excess of anionic organic ligand is incorporated to drive the binding dissociation equilibria toward insoluble polyvalent chelate and salt formation. Precautions must be taken in application to avoid premature coagulation of the water-borne resins by added electrolyte. Sequential or dilute surface addition of components is effective toward circumventing this instability problem. Surface areas of residential roofing products are typically quite low and can be satisfactorily protected with thin film inhibitor coverage toward achieving optimum adhesion and cost effectiveness. The versatility of the system allows for concentration and composition control of both the microbicide and binder ligands for optimum product performance. Most surprising and very unexpected is elimination of adverse surface blushing of polymer films accompanying ligand exchange yielding more hydrophobic structures. Quite significantly, blushing has been the primary impediment in development of transparent single-ply membrane technology of water-borne resins. This is particularly true in residential roofing where the luminous opacity accompanying the surface dew point temperature is esthetically unacceptable in the marketplace. The obviation of blushing in the present systems leaves only a degree of luster imparted by the transparent film without altering the original esthetic appeal.
As mentioned above, substrate surface wetting is instrumental toward achieving optimum chemical efficiencies of the present invention. As a general class of surfactants they can be nonionic, anionic or cationic. Representative types include alkyl- and alkyl arylethoxylates, sulfates, sulfonates and quaternary ammonium salts. Nonionic ethoxylates of synthetic aliphatic alcohols with low HLB are available under the trade name Renex from ICI Americas Inc., Wilmington, Del. Polyoxypropyl polyoxyethyl block copolymers available under the trade name Pluronic from BASF Corp., Parsippany, N.J. are also effective nonionics. Alkyl sulfate sodium salts available under the trade name Witcolate from Witco Chemical Corp., New York City, N.Y. are preferred in bleaching formulations for their stability. Alkyl sodium sulfo succinates, available from various suppliers, are preferred for most difficulty wettable substrates. Generally, wetting agents serve equally well in rewetting and therefor, can be applied independently in preparing the substrate surface or as a formulated component. Each formulations must be evaluated with regard to pot life to circumvent premature interactions which include the exchange of an equivalent amount of organic ligand as an integral part of the inhibitor system. Product selection is dictated by properties of the specific substrate and the necessary reduction of liquid surface tension to facilitate wetting which is readily apparent in droplet behavior upon surface contact.
The toxicity of metal salts over abroad range has been published in numerous technical sources such as "Dangerous Properties of Industrial Materials", 6th edition by N. Irving Sax. While any water soluble salts of polyvalent metals from the third, fourth and fifth horizontal periods of the periodic table can be used, judicious selection would focus on metals responsible for the inhibition observed on existing roof installations which include zinc copper and tin. Examples of salts which can be used in accordance with the present invention include, zinc acetate dihydrate, zinc sulfate heptahydrate, cupric sulfate pentahydrate, cupric nitrate trihydrate and stannic sulfate dihydrate. They are readily dissolved and commercially available. The deposition of these salts from solutions with positive spreading coefficients assures effective molecular coverage of the substrate surface which supports algae growth.
Any suitable exterior water-borne resins and organic ligands may be used in securing the polyvalent metallic inhibitors of the present invention via mechanisms of encapsulation, chelation and salt formation. The elastomeric roof mastics, which have been developed for adhesion, elongation and weatherability, exhibit optimum performance in transparent thin film application on sloped surfaces. As indicated above, anionic water-borne resin systems are preferred to secure polyvalent metallic cations in binding exchange equilibria and it is desirable to have films with good light stability and elasticity. Examples of polymer emulsions which can be used in accordance with the present invention are styrene-acrylic ester copolymers available from Rhone-Poulenc, Kennesaw, Ga. under the trade name Rhodoplas. The preferred acrylic ester copolymers which generally offer superior light stability are available from Rohm & Haas Co., Philadelphia, Pa. under the trade name Rhoplex. The particularly suitable resins are those which exhibit sufficient thermoplastic character to resists dirt pick-up and sufficient light stability to resist yellowing during service life.
The relative amounts of polyvalent metal salt, organic ligands can vary widely within the primary objective to accommodate both the specific substrate surface and service requirements. Of the total composition yielding the microbicide system more than about 85% is organic and the remaining inorganic salt content is ultimately reduced to less than about 5% as a result of leaching the monovalent by-product salts during service life. A preferred composition is 91% organic ligands and 9% metallic salt. Valence state and equivalent weight of the selected metallic salts are determining factors in establishing stiochometry and a substantial excess of organic ligand can be highly beneficial. While surface films uniformly applied can physically encapsulate metallic inhibitors the transfer of polyvalent metallic ions to the solid phase by cation exchange is a preparative feature which relies on receptor sites incorporated in anionic resin systems. The organic ligands exchanged in chelate or salt formation confer film compatibility and added durability of the microbicides. The preferred products exhibit lipophilic properties with enhanced microbicide activity, while the resin film serves to reduce surface erosion and prolong roof life.
The inhibitor system is readily produced by applying the dissolved polyvalent metal salt and resin emulsion in ratios ranging from 1:10 to 1:500 parts by weight respectively. Incorporation of wetting agent at levels comparable to metal salt are typical. The process is carried out by any suitable method such as spraying, rolling or brushing of components preferably on a clean, readily wettable surface. A preferred method is by simultaneous dual spray application of salt solution and resin emulsion. The quantities applied in coverage of exposed roofing surface is in the range of 0.01 to 3.0 pounds per square. The preferred level of application is in the range of 0.1 to 0.3 pounds per square. Versatility of the system in terms of both chemical composition and level of application permit adaptation to specific substrates as well as environmental exposure conditions.
The invention is further illustrated by the following examples in which all parts and percentages are by weight unless otherwise indicated.
Samples of asphalt shingle and cement tile were treated with various water-borne resins and exposed to atmospheric conditions in Central Florida. Samples consisted of light and dark shingle composites and unpigmented cement tiles. Resin emulsions were brush applied to the rough surfaces producing films approximately 3 to 5 mils thick. The samples were monitored with the following observations; plus signs indicating relative degree.

Given necessary atmospheric conditions, daily blushing was observed from sunrise until surfaces dried. The blushing effect was most objectionable on dark asphalt shingle and least noticeable on unpigmented cement tile. Soiling and yellowing were slight in each case but most apparent on the light gray asphalt shingle.
A residential site was selected for initial evaluation of wetting requirements on discolored product. The color of the original off-white asphalt shingle roofs North face was indiscernible alter six years service life. The soiled surface with approximately 3 in 12 pitch was sectioned for the following chemical evaluations. Wetting as a function of color removal by scrubbing and bleaching was examined for a series of surfactants in addition to uniformity in application of metal salt solution and resin emulsion. Surfactant selections were based upon preliminary examination of chemical compatibility and integrity of polymer films prepared on glass plates.

The roof surface, vertically sectioned in sixths, was treated with individual surfactants and mildly scrubbed to assess color removal as a first step. Sodium hypochlorite was then spray applied slowly, avoiding run off as much as possible, until the original shingle appearance was restored. Efficiency of the chemical bleaching via surface wetting was the major observable effect in this sequence. Zinc acetate solution was applied over the entire surface followed by resin emulsion over the lower half; both at approximately 1 gal. per 500 sq. ft. Two years have lapsed since the roof was treated with no evidence of reoccurring discoloration.
A Planned Unit Development of one hundred villas developed severe irregular discoloration on North facing roof exposures during a seven year life. A maintenance service was contracted to restore the original beige asphalt shingle roof appearance which involved initial cleaning/bleaching/rinsing followed by a subsequent annual maintenance treatment to remove reoccurring discoloration. A single 1500 sq. ft. roof with 4 in 12 pitch was isolated from the service at the mid point between cleaning cycles for comparative inhibitor evaluation. The test roof was treated in turn with sodium ethoxylated alcohol sulfo succinate (0.3%), zinc acetate (0.3%) and Rhoplex E-2540 acrylic emulsion (7.0%) at rates of approximately 1 gal. per 500 sq. ft. The test roof has shown no evidence of reoccurring discoloration during the 2 and 1/2 years since the inhibitor treatment was applied. The remaining roofs continue to be cleaned annually to remove the objectionable reoccurring discoloration, i.e. 2 additional cleaning cycles completed.
A 7 year old 4000 sq. ft. single family home with beige asphalt shingles was selected as a worst case of discoloration on a recessed shaded portion of the North facing roof with 6 in 12 pitch. The depth of microbial growth and the slope rendered the roof accessible only from the adjoining elevated sections on either side which exhibited irregular relatively moderate discoloration. The elevated surfaces were cleaned with 3% sodium hypochlorite solution containing 0.5% sodium 2-ethyl hexyl sulfate spray applied at a rate controlled to circumvent any run off. Using 5% sodium hypochlorite solution containing 0.05% dioctyl sulfo succinate sodium salt, the recessed portion was also cleaned without chemical loss. Chemical efficiency approaching that of solution reaction was achieved through controlled surface wetting; eliminating first black and then purple coloration in restoring the original shingle color without run-off.
Only the recessed portion of the roof was treated to permit comparative evaluation of zinc inhibitor system. The 0.2% solution of zinc sulfate heptahydrate was spray applied without additional wetting agent followed by a 5.0% active emulsion of Rhoplex EC 1685; each at approximately 1 gal. per 500 sq. ft. Neither the cleaned elevated or cleaned and treated recessed roof sections show any evidence of reoccurring discoloration approaching 2 years exposure.
Major manufacturer's composite asphalt shingles and cement tile samples were treated to evaluate alternative inhibitor systems. For this purpose, individual production samples of asphalt shingles, slurry coated and uncoated cement tiles were spray coated with 0.5% sodium ethoxylated alcohol sulfo succinate solution followed in turn with 0.25% copper sulfate or 0.25% stannous chloride and 3.5% active Rhoplex AC 264 acrylic copolymer emulsion. The treated samples, acceptable on visual examination and devoid of blushing on exposure, are well into the second year of exposure with no evidence of discoloration. Notably, accelerated exposures tests are also going forward at several sun-belt locations.

Florida Commercial Roof Cleaning
The Lockyer / Mallard History
In September of 1991 Alfred Charles Lockyer "AC" moved home from college. Having a family history of his Grandfather and his Father being successful business owners, AC had already decided he also wanted to be a roof cleaning entrepreneur. AC, recently engaged, knew he needed to quickly make his mark with some kind of roof cleaning business to support his new life with his wife. Contemplating this on his drive back from Texas where he attended college, AC had asked his father for an idea for a new business. Al Sr. had just had his home painted and the painter had cleaned his roof as well. Al Sr. passed on the idea of roof cleaning to AC and the seed was planted.
As AC traveled the 24-hour drive back to Florida he had plenty of time to plan for the inception of his new roof cleaning business. How do you clean a roof? What type of licensing does it require? How will I insure the company? Many roof cleaning questions and plans circulated within AC’s mind.
Once home AC and his father sat down to plan on what was to be with this new residential and commercial roof cleaning venture. It was decided that a pressure washer could do the job and one was purchased. Also was purchased a small long-bed pick-up truck. The first demo roof was chosen,” AC’s Grandmothers home” and the residential and commercial roof cleaning business was off.
Quickly “very quickly” AC realized that the pressure washer was blasting off the small stone finish “ aggregate” from the roofs surface. AC knew that if he continued pressure washing the roof that the damage would far out weigh the benefit of the cleaning. There had to be a better way of residential and commercial roof cleaning .
AC remembered back to an experience where he regularly cleaned his fathers screen room with bleach and water to remove mildew stains. AC then purchased a couple pump-up style sprayers and some discount bleach. Mixing the bleach and water together he made quick work of completing the cleaning of his Grandmothers roof. Best of all there appeared to be no damage caused to the roofs surface. That first roof was about 1800 square feet and took all day to complete.
AC then set his sights on a small neighborhood in Seminole County, Florida, Orange Grove Park. The homes there were about 4 to 5 years old and in desperate need of some roof cleaning. AC created some makeshift flyers and began knocking on doors for business. Quickly he had his first two customers. AC gathered his supplies (30 one gallon Albertson’s Bleach containers, a rope with a hook, some garden hose and 2 pump-up sprayers). His plan was to mix the chemicals from atop the roof with no need to go up and down the ladder. This was a good plan because AC was phobic of heights.
That first day in Orange Grove Park Alfred cleaned two roofs while operating under the name of Allstate Home Appearance Services. Orange Grove Park became AC’s residential and commercial roof cleaning testing grounds. AC did 27 roofs in Orange Grove Park, the first sold for $50.00 and the final for $225.00. AC had developed his process to include a holding tank for his bleach and a pump with a hose reel. AC could do two roofs with the current chemical capacity and had to refill during his lunch hour.
Now that AC had a residential and commercial roof cleaning delivery system it was time to work on the cleaning chemicals. Bleach and water did a fine job cleaning but simply could not keep a roof cleaner longer that six months to a year. AC knew that in order to charge enough for his residential and commercial roof cleaning service to afford insurance and workers comp as well as other compliance expenses he needed to get more longevity out of a cleaning. AC had spent seven years on and off working in the horticulture and nursery industries. AC had a vocational degree in horticulture and knew of the many fungicides on the market. If only through research and development a fungicide could be found that could be carried within a bleach and water solution.
AC by this time had polished his residential and commercial roof cleaning company and had a very impressive marketing program going. He began to attract the eye of several shingle manufactures that had residential and commercial roof cleaning problems servicing claims from mildew staining on their roofs. Companies like ELK and GAF lent their support early on and pointed AC in the direction of what they were researching for removal of mildew stains. Closet chemistry ensued and various adaptations and solutions were tested on un-assuming roofs through out Orlando. AC began to notice that a certain mixture was gaining time remaining clean long after other mixes had failed. This was to become the first residential and commercial roof cleaning “Duck Sauce”.
AC for some time had noticed that the name he was using for his company was very generic. AC wanted to brand his company so it was hard for anyone to forget him. In the spring of 1992 AC changed his companies name from Allstate to Mallard Systems. He incorporated a phone number of (877) DUCK-620 into his marketing and a large duck on the side of his truck. Oh and that new fungicide mix, that became the “Secret residential and commercial roof cleaning Duck Sauce”.
From merely the name change sales went up 30%. Customers would frequently ask AC “How many trucks do you have now? I see them everywhere.” AC had only one truck, it however was the most noticeable truck driving throughout the Orlando area. By now AC was cleaning consistently 10 – 15 roofs per week.
In April of 1992 Orlando saw a series of severe storms that spawned large hail stones. 100,000 roofs were replaced in Orlando and that nearly killed Mallard Systems. But out of adversity comes creativity. AC for a while had noticed that his chemical would run off of the roof and create clean spots on driveways, woof fences and home exteriors. Determined to survive AC decided to go head to head against the pressure washing industry and promote the Mallard System as the solution to damaging ineffective pressure washing on any exterior surface.
It paid off! Mallard Systems immediately rebounded amidst the re-roofing craze from the hailstorms. Because the Mallard System was so effective against mildew and organic staining and was applied so quickly, Mallard began to gobble up market share. AC as a small one-man one truck was beginning to get very busy at residential and commercial roof cleaning in Florida.
By Mallard Systems one-year anniversary AC’s wife Karen had joined the efforts and was riding shotgun in the old duck truck. The Mallard reputation had grown and now commercial customers wanted service. AC joined the Apartment Association of Greater Orlando in 1992. Some of Mallard Systems first commercial customers were Winter Park Villas Apartments, Vistana Resorts, Larry Cavalerro “Past AAGO President” and Seville on the Green. Mallard Systems commercial growth had begun.
Mallard Systems remained a small one-truck company until the fall of 1993. AC had begun to become overloaded with business and could no longer alone support himself and sell and service and book keep etc, etc, etc. It was time to expand the family business to include more family. AC only 23 yrs old now, convinced his father to come into the residential and commercial roof cleaning business and help out.
The business offices were moved into the upstairs apartment above Al Seniors garage and a sales person was hired. Two more trucks were purchased to total three service trucks and the Mallard Systems “Flock” was born. The next few years saw growth in a single year by as much as 400%.
In 1996 Mallard Systems moved from above the “garage” into their first commercial business facility in Altamonte Springs, Florida. That year Mallard Systems hired a Sales Manager and expanded their flock to six sales trucks, six service trucks and over eighteen employees. Mallard Systems had at this point become the most successful residential and commercial roof cleaning company in Florida to date.
In 1997 our growth made it obvious that they had out grown their little 2000 square foot facility in Altamonte. Mallard Systems had hired Jack Lynch to aid in the search for land to build a new building to house the flock and soon Jack himself became part of the flock. Fall of 1997 Mallard’s new roost in Longwood, Florida was completed and they moved right in. Salespersons were added and more “duck trucks” hit the road. A total of ten sales trucks and ten service trucks were out daily. The residential and commercial roof cleaning flock had grown to over forty employees.
In the fall of 1999 Mallard Systems decided to open its first branch in Tampa, Florida. That move coupled with the sales of the Longwood branch earned them the distinction of being a Florida 100 company. January of 2000 saw the opening of Mallard’s third facility in Delray Beach, Florida. With the addition of the Delray facility Mallard Systems completed the year 2000 with over five million dollars in sales. For that Mallard was awarded the Florida 100 once again. Mallard Systems now has 36 residential and commercial roof cleaning trucks and over 100 employees throughout Florida.
Mixed with this tremendous success and sales came bitter times for the Lockyer's and Mallard Systems. The fall of 2000 saw a Presidential Election marred with fraud and controversy. Earlier the Attorney General of the US began proceedings for an anti-trust lawsuit against Tech Giant Microsoft. The Stock Market was falling, chads were the talk of the day and the worst drought in 100 years grasped the throat of Florida. The mighty residential and commercial roof cleaning giant was wavering. Water restrictions and a declining economy were taking their toll and a move needed to be made. The decision was made to close the Delray Beach office. It was the hardest thing for the leadership to do. Not only were we about to cut out a branch only one year old but it had sold over 1.4 million dollars its first year in business. Hardest of all for the Lockyer's and Mallard was letting go over fifteen employees that’s livelihood depended on that branch. These were dark times.
The drought and the economy only seemed to slip deeper and so did Mallard’s sales. Another tough decision was coming. The Tampa branch was next to go. The Lockyer's could only hope that this radical, aggressive belt tightening could save the company. The closing of the branches had amassed over $700,000.00 in debt. The weight was almost too much to bear. The only positive during this dark time was that AC had been nominated for the Orlando Business Journals Up and Comers Award. Feelings were mixed. AC felt how could he relish this achievement with so much uncertainty surrounding the existence of Mallard Systems. AC attended the Up and Comers banquet with his wife and his parents not knowing if he made the cut. Forty nominees were taken but only 20 would be accepted. AC was chosen and awarded as one of the top twenty business leaders under the age of forty in Central Florida. This was a little bright spot in the storm of economic uncertainty.
By summers end the belt tightening had helped. Still heavily weighted in debt and uncertain Mallard had begun to emerge from the fire like a phoenix. It started to rain, fall season was coming and AC thought, “What possibly could happen worse than the boggled Presidential elections”. Well trials hit Mallard again. Early in September several ex Mallard and current Mallard employees left to start a competitive company. The Lockyer's were totally caught off guard and hurt by this move. What seemed to be a totally devastating move of betrayal was to be totally over shadowed two days later on September 11th 2001. God Bless, our problems now seemed so small, America’s perspective was changed forever. We were all forced to our knees.
The country and the economy dove sharply as though off a cliff. It was dark, but out of great adversity comes determination. The Lockyer's now with a glare in their eyes started to fight unbelievable odds. Economy, betrayal, debt, terrorism and rumors of Mallard’s certain demise became a call to war. Like the good ole days Mallard had something to prove. Could they lead the way and be more than what all naysayers expected of them?
Mallard Systems Longwood finished 2001 actually ahead of their 2000 branch numbers by more than 30%. Momentum grew! Each month that passed showed mark improvement over the past years numbers. Sales increased. Stability and moral improved. Debts were retired and Mallard Systems was back. Not back a little, back on top. Mallard began to re-enter the markets they had closed a year earlier. Not as branches but from Orlando. New residential and commercial roof cleaning management ideas and techniques were born. Business was done differently. Like the hailstorms of 1992 the adversities of 2001 had created opportunities and Mallard capitalized.
By the close of 2002 Mallard Systems was a break-even company. No losses, no gains but in the black. In that victory was the starteling fact that they had retired more than half of their debt. Sales for the Longwood residential and commercial roof cleaning market were up 30% and the residential division had its best year ever! By the close of the first quarter of 2003 Mallard Systems posted a 12% profit! Nothing admirable is ever easy! Mallard had been to the Gates of Hell, but never gave up.
2003 saw some changes to the line up at Mallard Systems. AC needing to pursue his own business style and gain independence split Mallard Systems with his father and again struck out on his own like he did in 1991. AC began a business to business focused cleaning company and named it TerraClean. His wife Karen again joined him as President of the parent company TerraServ Inc. The split of the little roof cleaning empire was completed in late May 2003.
TerraClean is a company focused on meeting the cleaning needs of schools, apartments, businesses, hospitals, condos, government, etc. Customers who once embraced Mallard Systems were easily converted over to the new TerraClean Company. Sales were healthy and good service abounded. TerraClean began to flourish because of its simple cause of excellent service with an excellent product. TerraClean finished up the year of 2003 with a substantial profit.
In 2004 Al Lockyer Sr. sold the 11 county Central Florida Mallard Territory to a British National living in Florida. Al was ready to retire and did so in 2004. After some time it was realized that this was not going to work out. In 2008 AC reacquired the piece of Mallard Systems that was sold. Now the entire residential and commercial roof cleaning company has been rejoined under AC's ownership and direction.
