They did an excellent job on the moss removal from our roof. Came on time, were professional and thorough, and cleaned up after. Could not be happier with the work.

Jorge did an excellent job cleaning my roof, gutters and replacing a wall vent that a woodpecker had destroyed. He also helped me with putting some scare tape on the roof vents free of charge. He's very punctual (came a few minutes early) and went out of his way to use two treatments on a portion of our roof that had been overrun with moss. He'll be my first recommendation to anyone needing these services.

Clayton cleaned my clogged gutters and removed the moss from my roof. He did a fantastic job. I was very pleased with his work ethic and the quality of service he provided at a very reasonable price. I was so impressed, I'm already signed up for a cleaning next year to preserve the roof and am planning on having him power wash my home in the near future. He truly deserves 5 stars.

What a pleasure to work with someone so dedicated to his work. He was on time and did a excellent job. We had a moss treatment for the roof, gutters and exterior windows. He was also able to put the moss treatment on our shed and clean it's gutter. It was a relief to find someone so reliable. We will certainly use Justice again.

Entered my project information on Thumbtack for pressure washing of asphalt driveway and unsealed concrete half basketball court. Clear N' Bright had best price. What made me feel they were a straight up (customer friendly) business was that they were quick to reply, answered all my questions, asked me questions to clarify job, and were very professional. They were able to accommodate the appointment to my schedule. I felt trust. So when they came to do the job I felt like they would do a good job. And they did! They had told me how long it would take, gave me additional maintenance tips and responded to all my questions in a friendly manner. The guys used a professional rotary pressure washing tool for both surfaces and then did a rinse to leave behind two clean surfaces. These guys were cool. I also asked about the other services they do and the cost. I got a quote for window cleaning and roof moss removal and treatment. I didn't proceed with those projects but the prices they gave me were very reasonable. I will hire them again. Thank You Clear N' Bright! you came through for me. You have a winning formula from what I see. 44

The moss was so green and abundant this year that my roof was beginning to looked like the inside of an Easter basket. Deciding that the job would take a professional, I contacted different companies asking for a quote. Paul from Gilland Window & Gutter Cleaning responded almost immediately. He asked for my address so he could take a look at the roof and came back with a very reasonable price the same day. He explained the process thoroughly, the moss would be scrubbed off the roof by hand as much as possible to avoid damaging the shingles and then the remaining roots would be treated by zinc sulfate. I gave him the go ahead and the work was done the very next day. I came home from work to a roof back to it's original color, with some white powder residue. The residue washed away with the next rain and the roof looks great! Paul contacted me the next day to ensure that I was satisfied, which I was. I'm very pleased with the responsiveness, efficiency, professionalism and value offered by Gilland Window & Gutter Cleaning and would recommend them to friends.

John is a one of a kind carpenter. He installed my hardwood floors and baseboard first and did a beautiful job. Later, I had him back to clean the moss off of my roof and do some repairs to it. Now, I am hiring him again to make me a farmhouse table. I wouldn’t hesitate to have him do any job. I would even wait for him to have availability to fit me in. I won’t have another carpenter in my house besides John.

ProMan was able to come right out the same day I got in touch with them. Jorge was very professional and sent an employee out to clean gutters, brush the moss of the roof and treat the roof. The price of the project was less than some of the other gutter cleaning places and well worth the money. They provided me with before and after pictures so I could see all the work that was done. I would use this company again.

Cleaned roof, gutters, windows and siding Excellent communication, very professional and timely. The work was done well and thoroughly the first time. Our roof had a huge amount of moss, and Spencer cleaned most off. The rest, which would have damaged the roof to mechanically remove, he treated. He told us what to expect as it died and fell off, which it did. He said that if any was left after 2 weeks, he would re- treat it. A little did remain, and when I called, he did exactly that. Great service, excellent work, and the best price (they offer a cleaning package that was like getting the Windows done for free compared to the other bids we got). Will definitely call them again next time we need these services.

Ward exceeded our expectations. First of all, he was punctual, polite and his work was beautifully done. He pressure washed a huge back yard patio with pavers and the entire driveway, both of which were covered in moss. The time it took and the amount he charged were both quite reasonable. I highly recommend him!

He did an excellent job on the roof. He did not use a pressure washer. Just a brush with a long handle and water. He also sprayed the roof for moss prevention. The roof looks great.

Extremely happy overall with the job, cost, appreciate the quick response and professionalism (would have given 4.5 stars if that were an option due to prefer to know all costs/recommended work in the initial estimate and slight cleanup remained) but Andrew and Ray relieved a major concern by efficiently and effectively cleaning entire roof and gutters and spraying moss deterrent. Much appreciated, we would hire GPA again for future gutter maintenance.

Moss Busters and Darryl did an outstanding job on our roof. He explained to us the process and treated our roof gently and professionally. He did clean up all the dead moss and sprayed down our windows. He put the moss killer and retardant on the roof after he had cleaned up which tumbled Down the roof and landed on the ground and hot tub cover. He said it would not hurt anything because it was just soda. But it left a mess on the ground. Wish he would have waited to clean up after he put The powder on the roof

Q & A

Answers to commonly asked questions from the experts on Thumbtack.

Can a roof be cleaned?

Yes roofs can be cleaned, and yes, it’s a real thing. Roof cleaning may actually be a wise investment to prolong the life of your roof. Overgrowth of moss, grime, lichen or algae can all shorten the life of your roof. If you have black streaks growing on your roof, they are likely caused by gloeocapsa magma algae spores that have landed on your roof and taken up residence. Once the algae has grown into streaks, the organism has usually been growing for several months and it’s high time to have it removed. If you live in a rainy part of the country, such as the Pacific Northwest, there’s a good chance you’ll find moss growing on your roof at some point. The northern part of your roof, as well as any parts that remain shaded all day, will provide a wet, cool haven for moss to flourish. Unfortunately this water-absorbing moss can damage your shingle roof, leading to rot if not removed. Beyond roof health and function, a clean roof can boost your curb appeal and potentially boost your home’s resale value. The national average for roof cleaning costs ranges between $270 and $350, although prices can be higher depending on how large your roof is, how steep your roof is, and what type of cleaning is necessary. Typically pros use either a pressure wash or chemical wash (made with a concentrated bleach solution) to remove algae, lichen, moss and dirt.

Why do I need to clean my roof?

Over time, algae, moss, lichen, dirt and even salt (if you’re near the ocean) can build up on your roof. These buildups can affect the look and function of your roof unless removed. The buildup of organic materials such as moss on a shingle roof can prevent water from sloughing off as it normally would. Trapped water can rot the roof or cause early deterioration of your shingles. Even if you don’t have a shingle roof, moss and lichen absorb water, and that wet material adds weight and stress to your roof — as well as providing a home for insects and other pests, and collecting dirt. For reflective, cool roofs that redirect heat away from the home, algae and moss growths can hamper their ability to deflect the sun, which can affect utility bills. Visually, moss, dirt and algae growths on a roof can have a negative effect on perceived home value and curb appeal. For example, black algae streaks on your roof may cause a potential homebuyer to assume that the roof might need repair or replacement, when it only needs to be cleaned.

How much does it cost to clean a roof?

The national average for roof cleaning costs ranges between $270 and $350. Factors that can affect the cost to clean your roof are the height of your house, the size and pitch (steepness) of your roof, and the complexity of your roof’s design and accessibility. Geographic location also plays a role in roof cleaning costs as regional labor rates and area costs to do business will vary. There are several ways to clean a roof. The most common is pressure washing. Industrial pressure washers can spray over 3,000 pounds per square inch (psi) of water — which is much too powerful for roof cleaning, and may tear off shingles and damage your roof. Confirm that the roof-cleaning pro you choose will only use a low-pressure sprayer to protect your roof investment. For large algae or moss growths, pros often recommend a combination of low-pressure washing with a bleach-based chemical solution. This is referred to soft washing and should handily remove any growths taking over your roof.

What chemicals are used to clean roofs?

Roof cleaning is done to remove moss, lichen, algae, and buildup of other grime and dirt. There are several methods for roof cleaning, which can include a chemical soft wash, pressure washing, low-pressure washing and hand washing. When a chemical soft wash is used, a bleach mixture is sprayed onto the roof. The bleach-based solution is absorbed by the algae or moss, which dies from exposure to the chemical. The roof is then sprayed with a low-pressure rinse of water, which loosens the now-dead material, allowing it to slide off the roof.

For homeowners, the Asphalt Roofing Manufacturers Association recommends a mixture of 50 percent laundry-strength liquid chlorine bleach and 50 percent water. Professional roof cleaning companies will use an industrial mixture that is still safe but may be more effective in eliminating algae and moss growths. Asphalt shingle roofs are the most common type of roof, but each roofing material will have its own cleaning needs, so it’s best to consult with your roofing pro before diving in. Don’t do it yourself unless you can safely navigate your roof, the chemicals and a sprayer system. When in doubt, leave it to the pros.
