Clayton arrived on time and ready to go and he briefly explained the work he was going to do. He had a professional and friendly attitude and got right to work. He did a great job cleaning my roof and gutters and applying a moss treatment. My roof looks 100% better and I am very happy with his work. I highly recommend Clayton!!!

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.

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

Criss and his crew took out three huge cedar trees for us, built a new cedar fence and a new picket fence. They were so quick and efficient when removing the cedars. We were expecting our yard to look like a warzone after those trees came down, but Criss and his crew did a great job cleaning up after. The new fences look great. We are very happy with the services Criss provided and will definitely call him again in the future.

First off, Holloway Home Maintenance provides a great value, especially for the level of service they provide. Monte did a great job cleaning the roof and even took pictures to show us what it looked it. It put us at ease knowing HHM is licensed and insured - it is worth paying a little more for! We know who we will be hiring next time!

Gutter Pro America provided excellent service at a fair price. The team was very respectful of my property. After they finished cleaning my roof and gutters, they cleaned up all the debris that had fallen on my lawn and deck. I highly recommend this company.

Q & A

Answers to commonly asked questions from the experts on Thumbtack.

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.

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.

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.

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.
