Can You Pressure Wash A Shingle Roof ?

We often are asked “Can you pressure wash a shingle roof” ? The answer is yes, if you don’t care about ruining your shingle roof! Another question we get asked is “If I pressure wash a shingle roof, will it be clean” ? The answer is Yes, and 1/2 of it will be on the ground!

Dirty Shingle Roof in Tampa
Tampa Shingle Roof Cleaned Properly

So, if pressure washing will ruin a shingle roof, why do some roof cleaning companies in Tampa still use this method to wash a roof. The answer is ignorance and/or greed! Let us say a shingle roof cleaning costs 500.00. If we were to use a pressure washer to clean your roof, we could keep every dime of that 500.00 Roof Cleaning Chemicals are not cheap, and like everything lately, their prices have gone up considerably! WE only clean roofs chemically, w/o the use of any pressure at all! Though it costs us more than if we were to use a pressure washer, it is the right way to clean a roof.

Your shingle roof is basically a piece of either asphalt or fiberglass, that has ceramic granules glued to it. Some shingle roofs are what are called algae resistant. They use the 3M Algae Block System that has copper granules mixed in with the ceramic granules to help prevent the dreaded roof algae. The idea is, every time it rains, the water washes the copper sulfate released by these granules. Copper Sulfate is a natural algaecide, and it does help to keep the roof clean. However, here in the Tampa Florida area, the heat and humidity overwhelms even these algae resistant shingles, and as the result, the roofs get dirty despite the 3M Algae Block system! We clean so called “algae resistant” shingle roofs every week, so we know!

Never ever allow any roof cleaning company to use a pressure washer to clean your shingle roof, under any circumstances! Call Apple Roof Cleaning Tampa if you want your shingle roof cleaned the right way, at 813 655 8777

Asphalt Shingle Roof Cleaning Tampa

Asphalt Shingle Roof in North Tampa Before Cleaning
Asphalt Shingle Roof in North Tampa 33647 after we cleaned it

We do quite a lot of Asphalt Shingle Roof Cleaning in the Tampa Florida area. This customer was up in Tampa Palms in the 33647 Zip Code. Usually the Tampa Palms Homeowners Association will not let an asphalt shingle roof get this dirty, but it does not matter to us how dirty a roof is! As long as the roof was never improperly cleaned, we can usually make it look almost brand new again. In fact, several of the neighbors were so impressed by our work, they asked us for a business card! They plan to use us, when the time comes for them to clean their roofs.

This customer just bought this home, and moved here from Indiana. We were talking about those great Pork Cutlet Sandwiches, and that awesome Skyline Chili they have up there! He is a Notre Dame Football Fan, and I have been to South Bend Indiana to watch them play Michigan one year. We referred him to a good pressure washing company, because as you can see, his sidewalks looked terrible. We are a roof cleaning company, and we do not even own, or want to own a pressure washing machine! Back in the early days of our company, we used to have pressure washing machines on our trucks, but found that they scared our customers! Several times we heard “You guys do not plan on using that pressure washing machine on our asphalt shingle roof, do you” ? So we removed the pressure washers from our trucks. A Pressure Washing Machine has no place in a roof cleaning company. They ruin peoples roofs! If you have any type of roof that needs cleaned, call us at 813 655 8777 to get an idea of your roof cleaning cost.

Repeat Tile Roof Cleaning in Tampa Florida

He wanted to put his home for sale, and is asking top dollar for it, so he wanted to get his tile roof cleaned again, so everything was perfect.

All About Roof Cleaning in Tampa

Here is a great roof mold article by a retired university profesor who lives in a deed restricted Florida Community.

I do not agree with some of it, but there is some great information on what is growing on peoples roofs here in the Tampa Florida area.

He talks about Zinc Strips preventing the re growth of Algae on roofs, but they don’t work very well here in the Tampa Florida area, unless they are installed every 3 to 4 feet on the roof, and then they become pretty unsightly. I also don’t agree with his statements about using bleach based chemicals to clean a roof with.

Apple Roof Cleaning has cleaned over 25,000 shingle and tile roofs in the 20+ years we have been in business. Yes, we have damaged some plants, despite our best efforts to protect them, but never have we damaged any roof by our cleaning process.

ALL ABOUT ROOF CLEANING

by Dr. Victor H. Morgenroth

Dr. Morgenroth is a Keys Gate resident who is a semi-retired, adjunct professor of neurology at UM. He was a principal administrator in the Environment Health and Safety Division of the Organisation for Economic Cooperation and Development (OECD) for 20 years; prior to that I was a Group Leader in the Toxicology Division at the Center for Food Safety and Nutrition in the US Food and Drug Administration (FDA). Previously, he was on the faculty of several medical schools in neurology, pharmacology and psychiatry.

Having your roof cleaned actually makes sense. I know most of us were slightly put out by receiving a roof cleaning notice from the Keys Gate Management Association. Although it read a little like an ultimatum and you probably wondered who the inspector of your roof was and what their qualifications were, it turns out that roof cleaning is not a bad idea at all. Check out the pressure washer review here using which you can clean your roof and various other places around the house by your own.

It isn’t just aesthetics. While people like to say that dirty roofs lower a property’s value and may make it hard to sell, and according to professionals the “dirt” on a roof actually shortens its life span and can even present a health hazard. Furthermore, the “dark stains” on a roof act as a sponge to absorb the sun’s heat, which causes a rise in the temperature inside a home or building, creating higher air conditioning bills, that’s why we usually recommend getting a Spanish Tile Roofing on your home since it’s easier to clean.

The dirt isn’t just dust – It’s alive. Some of the black or very dark roof stains are caused by a resilient type of algae, Gloeocapsa magma (a type of blue-green algae commonly found in climates with warm, humid summers). The algae grow in standing water, as well as in our lakes and ponds. The algal spores are carried to our roofs from the water sources by the wind and birds, and then from roof to roof where it grows and feeds on the limestone filler in asphalt shingles and the real dirt on tile roofs maybe in some cases the tiles themselves. Worse still, as the algae grow, they retain water and foster the growth of other roof inhabitants.

The black stains are also very likely to harbor a number of molds or fungi. Unlike algae the fungi on our roofs lacks chlorophyll. They are unable to manufacture food from raw materials. So, it must get nutrition from some form of organic matter. To thrive, these heterotrophs, who used to be called saprophytes, also require a warm, humid environment.

Fungi normally begin their life cycle as an airborne spore that settles on roofs, especially the asphalt-shingle ones. The spores on the northern exposure of the roof stand a better chance of survival because that portion of the roof is the last part to dry after a rain or morning dew. This raises the humidity on the surface of the shingle, thus creating a perfect feeding and breeding ground.

The tar used in roofing is fossilized, dead organic matter — and an important food source for fungi. Asphalt, at the granule base, is normally consumed first. Once these granules dislodge, accelerated deterioration will occur. Ceramic granules represent the outer hard shell that protects against hail and other falling debris. Ceramic granules protect against damaging UV radiation and insulate the roof against extreme heat. So you can understand that their dislodgement by the growing fungal colonies can be detrimental to our roofs’ longevity. Surprisingly, the blue-green algae are also food for the fungi.

While not all mold (fungi) and algae pose a health danger, some are harmful, especially for us older folks, younger children and people who suffer from asthma and respiratory problems. Their spores, which are on your roof, can get inside your home because they end up on the driveway and walkways from rain, and are easily tracked inside. They can even be drawn into our air conditioning systems and eventually populate our ducts.

Different mold species can have varying health effects, but it is important to remember that any excessive mold growth needs to be taken care of, regardless of the species. Any excessive mold growth can lead to increased allergies, toxicity, and house/building structural problems.

For those interested, this box describes some of the most common fungi likely to be found on our roofs and their possible health effects. While “sick building syndrome” has been talked about frequently in the media, it isn’t always reported that this syndrome is often caused by faulty or leaking roof assemblies that result in fungal infestations. It isn’t, as reported, always due to chemicals in carpeting.

Don’t Panic!

Most of us have immune systems that are fully capable of resisting the effects of fungi described below. As a result it would be highly unlikely for any of us to suffer any of the ill effects described. But if fungal colonies are allowed to persist and multiply then the high concentrations of the molds and their volatile organic chemical metabolites might be sufficient to increase the risks from our exposure to them.

Stachybotrys chartarum (atra) molds can thrive on water damaged, cellulose-rich material in buildings such as sheet rock, paper, ceiling tiles, insulation backing, wallpaper, etc. In the majority of cases where Stachybotrys is found indoors, water damage has gone unnoticed or ignored since it requires extended periods of time with increased levels of moisture for growth to occur. Stachybotrys is usually black and slimy in appearance. Events of water intrusion that are not addressed quickly tends to support the growth of more xerophilic fungi such as Pencillium and Aspergillus.

Stachybotrys is another fungi that has the ability to produce mycotoxins, ones that are toxic and can be immunosuppressive. Exposure to these mycotoxins can result through inhalation, ingestion, and dermal exposure. Symptoms of exposure include dermatitis, cough, rhinitis, nose bleeds, cold and flu-like symptoms, headache, general malaise, and fever.

The Cladosporium genera of mold are pigmented dark green to black in the front, and black on the reverse with a velvety to powdery texture. One of the most commonly isolated from indoor and outdoor air, Cladosporium spp. are found on decaying plants, woody plants, food, straw, soil, paint, textiles, and the surface of fiberglass duct liner in the interior of supply ducts.

There are over 30 species in the Cladosporium genus. The most common are C. elatum, C. herbarum, C. sphaerospermum, and C. cladosporioides. These fungi are the causative agents of skin lesions, keratitis, nail fungus, sinusitis, asthma, and pulmonary infections. Acute symptoms of exposure to Cladosporium are edema and bronchiospasm, and chronic exposure may lead to pulmonary emphysema.

Aspergillus is the most common genus of fungi in our environment (it especially likes to grow on corn plants) with more than 160 different species of mold. Sixteen of these species have been documented as causing human disease. Aspergillosis is now the 2nd most common fungal infection requiring hospitalization in the United States.

Aspergillus fumigatus. The most encountered species causing infection. It is seen abundantly in decomposing organic material, such as self-heating compost piles, since it readily grows at temperatures up to 55 C. People who handle contaminated material often develop hypersensitivity to the spores of Aspergillus and may suffer severe allergic reactions upon exposure.

Aspergillus flavus. The 2nd most encountered fungi in cases of Aspergillus infection. It is also known to produce the mycotoxin aflatoxin, one of the most potent carcinogens known to man. In the 1960s, 100,000 turkey poults in Great Britain died from ingesting contaminated feed. Most countries have established levels for aflatoxin in food. However, the risks associated with airborne exposure are not adequately studied and no exposure standards exist.

Aspergillus niger. The 3rd most common Aspergillus fungi associated with disease and the most common of any Aspergillus species in nature due to its ability to grow on a wide variety of substrates. This species may cause a “fungal ball”, which is a condition where the fungus actively proliferates in the human lung, forming a ball. It does so without invading the lung tissue.

Fusarium spp.,common soil fungus and inhabitant on a wide array of plants, this fungi is often found in humidifiers and has been isolated from water-damaged carpets and a variety of other building materials. Human exposure may occur through ingestion of contaminated grains and possibly through the inhalation of spores. Fusarium spp. is frequently involved with eye, skin, and nail infections.

Several species can produce the trichothecene toxins which target the circulatory, alimentary, skin, and nervous systems. Vomitoxin is one such tricothecene mycotoxin that has been associated with outbreaks of acute gastrointestinal illness in humans. Zearalenone is another mycotoxin produced by Fusarium. It is similar in structure to the female sex hormone estrogen and targets the reproductive organs.

Penicillium fungi are commonly found in soil, food, cellulose, grains, paint, carpet, wallpaper, interior fiberglass duct insulation, and decaying vegetation. Penicillium may cause hypersensitivity pneumonitis, asthma, and allergic alveolitis in susceptible individuals.

The genus Penicillium has several species. The most common ones include Penicillium chrysogenum, Penicillium citrinum, Penicillium janthinellum, Penicillium marneffei, and Penicillium purpurogenum.

These fungi have been isolated from patients with keratitis, ear infections, pneumonia, endocarditis, peritonitis, and urinary tract infections. Penicillium infections are most commonly exhibited in immunosuppressed individuals.

In conclusion, during the digestion of substrates, fungi secrete enzymes into nutrients in order to break down complex compounds into simpler compounds that can be taken up by the fungi and used as nutrition. These digested nutrients produce secondary metabolic byproducts called mycotoxins that are released to give the fungi a competitive edge over other microorganisms and fungi. Unfortunately, mycotoxins can also be toxic to humans causing a variety of responses including cold/flu-like symptoms, sore throats, headaches, nose bleeds, fatigue, diarrhea, dermatitis, and immune suppression. Some mycotoxins may also be carcinogenic and teratogenic. Molds that have been known to potentially produce these toxins are Acremonium, Alternaria, Aspergillus, Chaetomium, Cladosporium, Fusarium, Penicillium, and Stachybotrys.

Even though these molds may potentially produce mycotoxins, they will not do so unless specific environmental conditions exist. Currently, it is unknown exactly what conditions promote the growth of mycotoxin production and more scientific research needs to be conducted on this topic for it to be fully understood.
