ROOF CLEANING IS NOT A “PRESSURE WASHING” JOB!
We do not use pressure washers to clean roofs. Please do not let anyone clean your roof with a pressure washer! If someone offers to use a pressure washing method, pay attention to the words they use. They know that anyone with common sense knows that pressure cleaning a roof is bad idea. They have to try to sell you on the idea that using a pressure wash approach is a good idea. A roof shingle is very fragile and those gritty roof granules is what protects the main underlying membrane. Those gritty roof granules wash off real easy, even with rain. The older a roof is the easier it is for the roofing granules wash off. You can look in anyones gutter at any time and find a good amount that washes off naturally. Using a gas powered pressure washer, even at their lowest settings, can produce a good amount of pressure. Low pressure is what comes out of your garden spigot and spigot pressure is the maximum pressure I would suggest using on a roof shingle. If it’s hooked up to a gas powered pressure washer than I say “no way”! It’s not low pressure.
If you’ve made it this far than I know you’re doing your homework. In the paragraphs below is a link directly to the largest roof shingles manufacture Timberline® GAF. These people make the shingles for 92% of the homes in the United States. In the link you will find their suggestion for the use of bleach-based detergents to clean the shingle and avoid the use of a pressure washer. We follow these manufactures suggestions. Below we will talk about roof cleaning, moss and algae, as well as the different types of roofs such as asphalt, cedar and slate roofs. We will also address the common concerns with the use of a bleach based detergent. We will discuss the protocol for covering and protecting delicate landscape. Our bleach based soap is biodegradable yet very effective in creating long lasting solution to your roof issue. It leaves no residual toxicity. It is simply applied to the roof using a small 12 volt, 45 psi detergent pump. There are no pressure washers used to clean the roof shingles of all types.
Pressure washing the roof also fails to solve underlying problem. Moss and algae stains are simply infections of the roof. Moss is like a weed. If you crop a weed at the top it comes back thicker and more full. Anything less than a 100% kill ratio on the roots of moss is a temporary solution. Anything less than a 100% kill ratio all the dark algae spores is a temporary solution. A full sterilization is the best defense against the stain returning. Our safe detergents can kill the moss and dissolve the algae staining. It creates a 100% kill ratio on all of the moss and algae and solve the infection completely. These 3 pictures below are a 4 month time lapse with one of our treatments. The treatment kills the moss instantly but it takes time to decompose, dry out and fall away over time. This was a severe case that took 4 months to come clean. The typical roof with moss takes roughly 90 days to fall away. Since the roof is so fragile we don’t have the option of blasting the roof moss with a pressure washer or scrubbing away with a stiff brush. Instant gratification can only be achieved by using an aggressive type cleaning. For the long term integrity of the roof its best to kill the moss and simply allow it to fall away naturally.
The 3 pictures above are time-lapse pictures taken roughly 45 days apart. We treated and killed the moss. We then allowed the moss to decompose on its own. This was a 20 year old roof that could never withstand the amount of pressure needed to remove such a heavy infestation of the roof. We have a proven non-pressure method that is endorsed and suggested by all roof manufactures. We are not dealing with a stain but rather a living pest. Our approach to a clean roof is not to clean the roof but rather to solve an infection. A clean roof is merely a by-product of solving the infection. We are a licensed NJ State Home Improvement Contractor Lic. # 13VH06353700. We are insured with workers compensation for every employee and general liability.
There is no aggressive scrubbing or power washing involved in cleaning a roof. We strictly follow all roof manufacturers cleaning instructions and use the recommended detergents approved by Timberline™ GAF. Our detergents are safe, biodegradable and effective. We are an Angie’s List company with an A+ Grade.
Roof cleaning is one of the most dangerous services performed as home or building maintenance. Protect yourself and verify your cleaning contractor can provide proof of general liability and workers compensation insurance. Clients rarely ask for workers compensation verification. Consider the legal costs if a contractor falls from your roof and is permanently injured.
ROOF CLEANING: WHAT’S EATING YOUR ROOF?
Thompson Roof Cleaning and Power Washing LLC is located in Woodbridge NJ. We have 20 years worth of exterior cleaning experience for central and northern NJ. We will provide all of our roof cleaning knowledge to help you in your project. Your roof is most likely the most expensive part of your house. Find comfort in hiring a professional roof cleaner that specializes in this delicate process. Black stains, algae, moss and lichen can easily be cleaned from your roof without using a pressure washer. Whether the staining on the roof is dark black algae stains, moss or lichen, it is all treated the same. This is an infection of the shingle. Moss develops a root system into the shingle. If you scrub or pressure wash, you did not solve the problem. We use a proprietary foaming detergent that is approved by all major roof shingle manufacturers. We can provide a quote over the phone for most cleaning projects.
Moss: Moss is like a weed. It develops a root system into the shingle. Moss can be safely removed but it is not a quick process. We do not try to scrub, scrape or pressure wash the moss from the roof because those 3 methods can damage the shingle. We apply our detergent will instantly kill the moss at the root. We leave the dead moss on the roof to dry out, decompose and wash away with rains. It take on average 90 days of non-freezing weather for the dead moss to wash away on its own. It never doesn’t come off. It always does, just not overnight. We will not use a pressure washer and compromise the shingle to give instant gratification. If you demand instant gratification and you need the moss washed away instantly, we will gladly pressure wash it if you sign-off and assume all responsibility for potential damage.
Lichen: Lichen is a fungus and an algae. If you have these on the roof you will most likely find them on trees in the surrounding area. If you try to pick one from the bark you will find it very difficult. Lichen attaches itself very firmly as it does on roof shingles. The treatment will kill the lichen on contact. It will take several weeks for the dead lichen to dry out and wash away. If you try to remove lichen instantly by scrubbing or pressure washing you will most likely remove the roof granules as well and leave a scar on the roof.
BE THE ENVY OF YOUR NEIGHBORS
Every Full Roof Treatment is Backed by Our 3 Year Spot-Free Warranty!
That is correct. Each full roof treatment is covered for 3 years against all organic staining such as mold, algae and moss. We can apply a safe biodegradable detergent and treat the stain at the root to eliminate the problem completely. We use small 12 volts pumps that deliver the detergent to the roofing shingle. The pressure is less than what comes from an average garden hose (45 psi). We try to avoid walking on the roof if possible. Cedar and slate roofs are never walked on. Asphalt shingle can be walked if it’s safe. Check out this roof cleaning article written by Angie Hicks, owner of Angie’s List. Roof Cleaning Article.
Soft-Wash | New Technology Exterior Cleaning
This soft-wash process can be used on all surfaces including stucco, vinyl, cedar, and even painted surfaces. Our pumps and machines are all calibrated to deliver high volumes of water at low-pressure. We have the right cleaning products to counter mold, dirt, grime, bird droppings, egg, black gutter stripes, and more. Every surface is pretreated to permanently kill mold before any soft washing or rinsing begins. This process of pretreat fully sterilizes the area and allows it to stay clean 4-6 times longer than traditional high pressure washing.
IS ROOF MOLD KILLING YOU, AND YOUR WALLET?
Roofs with moss, algae, mold, lichen, and black stains will retain more moisture and cannot reflect the sunlight. As a result, this creates higher temperatures in your attic increasing cooling costs in the summer. Additionally, these living organisms are literally eating away at your roof. As the stain grows the roof starts to hold even more moisture allowing more algae, moss and other organism to chime in. We consider these type of problems to be “pest control” issues and we treat them accordingly. Since we do not pressure wash roofs the desired results are not always instant. Moss can develop a root system into the shingle, just like a plant. Some moss may remove easily, but some may be firmly attached. If the moss is pulled off, the roofing granules may always remove with the moss and leave scars on the shingle. After our proprietary disinfecting detergent is applied to the moss it will die off immediately. It will decompose and the root system will release on its own. Then Mother Nature takes over and the moss will come off with each rain. The average time is 60-90 days before all of the moss is removed, depending on temperatures and how much rain is applied. Roof moss removal in New Jersey is partially responsible for many unnecessary roof replacements.
We specialize in cleaning every type of roof material such as asphalt, slate, cedar, and commercial rubber, vinyl or EPDM
New Jersey SLATE ROOF CLEANING
Slate roofs are never walked. We treat all slate roofs from the gutter line to prevent any loose tiles from dislodging. Black staining on a slate roof dissolves instantly and is then washed away at the first rain. Any solid items like moss or lichens will die immediately during treatment. It is left to dry out and decompose. After it gets a chance to fully dry out it will wash away with rains. This usually happens within 90 days of treatment. It is not impossible for it to take a bit longer. Especially with heavy lichen. If after 90 days there is still moss or lichen we will service the remainder free of charge. This is included in the warranty. If you’re looking for instant gratification, a non-pressure treatment may not be for you. Our method is the least aggressive way to clean a slate roof. The lesser the aggression of the cleaning method, the slower the process. With a more aggressive cleaning like scrubbing or pressure washing you can achieve more instantaneous results, but be prepared to dig a little deeper for the cost. Aggressive methods are dangerous and require more intense physical labor.
New Jersey CEDAR ROOF CLEANING
Before and after cedar roof cleaning results without using a pressure washer.
Immediately after treatment any black staining that was on the roof will have dissolved. Much of it will eventually be washed down the gutter system. It will have no adverse effect on surrounding landscape. Moss and lichens do not come off right away. We are not scrubbing or power washing the roof. We are applying a treatment that kills moss and lichen. It will dry out and decompose. These 2 growths develop a root system into the roofing shingle. It’s wise not to forcibly remove moss and lichen. Scrubbing or pressure washing the moss will give you instant results at the expense of releasing a lot of the roofing granules. Our treatment will kill moss and lichen within 5 minutes of treatment. It will die, dry out, decompose and wash away little by little with rain. It will not clog the gutters.
Cedar roofs are in a class of their own. A cedar roof is designed to last 40-50 years. Mold and algae can soften cedar and cause premature decay. Cleaning a cedar roof really pays in the long run. Though certain after-market stains and cedar roof sealers look nice, they are not mandatory. Applying stains and sealers on cedar shingles can actually trap moisture. Cedar roofs are designed to breathe freely. When a cedar shingle start to fester mold, moss, and/or lichen the shingle will start to retain moisture. This extra moisture retention will allow the mold and moss to grow exponentially faster, This is the reason why roof growth can explode within a 2 year period. You may see signs of it at one point then find a full blown epidemic by the next season. Cedar roofs are very gratifying to clean. Results are instant and dramatic. The only drawback is that cedar roofs can not be navigated. You cannot walk on a cedar roof.
ASPHALT ROOF CLEANING
Never should roof shingles be power washed. Water pressure can dislodge large amounts of roofing granules and shorten the life of the roof. Water alone will not kill the organisms that cause roof stains. The manufacturer suggests chemically cleaning asphalt shingles. Maybe you’ve noticed those tiny little particles of grit in your gutters. Those are particles that may have washed after a hard rain. So, just imagine what would happen if you let someone pressure wash your roof! We at Thompson Roof Cleaning & Powerwashing follow strict guidelines for all roof cleaning procedures.
Thompson Roof Cleaning Procedure – Manufacturer Approved!
Our treatment of a roof includes the use a foaming anti-microbial roof cleaning detergent which contains both an algaecide and fungicide. Application of the foam uses a pressure not greater than 65 psi. This is the equivalent to the pressure of most garden hoses. We guarantee a 100% kill ratio of roof growths including moss, algae, mold and gleocapsa magma (this is the strand that creates those ugly black stains on asphalt roofing shingles).
