Q & A

Answers to commonly asked questions from the experts on Thumbtack.

How often should you clean your roof?

Some roof cleaning companies recommend that you clean your roof every couple of years, but you might need to do maintenance every year depending on the type of roof you have, the climate and the weather. Roofs in harsher climates tend to require more frequent cleaning.

Can a roof be cleaned?

Yes roofs can be cleaned, and yes, it鈥檚 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鈥檚 high time to have it removed. If you live in a rainy part of the country, such as the Pacific Northwest, there鈥檚 a good chance you鈥檒l 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鈥檚 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鈥檙e 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鈥檛 have a shingle roof, moss and lichen absorb water, and that wet material adds weight and stress to your roof 鈥 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.

Is it worth it to hire a roofer?

There are several reasons why it鈥檚 worth it to hire a professional roofer instead of attempting it yourself. The first is safety. Roofing is inherently dangerous, as a fall from a roof could seriously injure or kill you. Roofers have specialized equipment and training to help prevent accidents.  

Next is experience. Roofers know how to spot problems (leaks, missing shingles, moss or mold growth, etc.)  in your roof that could potentially save you from costly repairs down the road. 

And finally, roofers save you time by getting the job done quickly and with a high degree of quality.

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鈥檚 best to consult with your roofing pro before diving in. Don鈥檛 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鈥檚 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 鈥 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.

Clayton did a great job of cleaning the roof. It was in pretty bad shape. I was impressed for the amount of time they took to clean the roof. They also cleaned all the moss that fell on the house siding and driveway after they were done. Great job.

Couldn鈥檛 have asked for more! Jose removed the moss from my roof, treated it the roof, pressure washed the driveway, cleaned the gutters AND cleaned everything up. I will definitely be using Goodbye Moss in the future.

Our roof went from resembling a Wooly Mammoth to looking like a brand new roof. Our gutters had been neglected and contained composted debris that we discovered was ideal for growing oak seedlings and a few weeds. The roof and gutters are now all sparkling clean - he even cleaned the gunk off the underside of the gutters, the fascia board, and eaves.

I had my roof cleaned by Emerald City Power Washing, and I couldn't be happier. Communication was clear and often, and very punctual. Roof looks great! Ryan did a great job keeping his work area clean too, which was appreciated. Very recommended.

Hugo and team did an absolutely AMAZING job cleaning my parent's property. What started as a bid for cleaning the roof turned into a job cleaning the roof, patio, sidewalks and sport court. It is evident he takes great pride in his work, and he should because the results speak for themselves! He was communicative, thorough, and a pleasure to work with. We are eager to refer him to anyone that might be in need of his services. Thank you Hugo, you and your team are in a league of your own!

Our roof was in a dire need of a thorough cleaning. Marcos from Diamond Pro Roofing came out cleaned it off so well, I was fine with the mess of moss, branches and leaves sprayed about all around my yard. But nope. Marcos then went ahead and cleaned up all the debris and left my yard looking better than it was. Oh, and he even fixed a down spout I put off for the longest time. Sometimes it pays to pay someone not as lazy as yourself. Thank You!

Quick to respond, good value and a very well done job. They gave me a good debrief after the cleaning was done to talk about my roof and the current status of it. Would use these folks again.

Leo was wonderful to work with! He was very responsive, from my initial inquiry to the completion of the job. I had him clean the roof of my 2-story, 200 sq. ft. Tuff Shed, as well as my house gutters. He sent me photos when the job was done and even added some moss killer to a patch on my roof. He did excellent work for a very fair price. I definitely recommend him and would hire him again!

So glad I went with Diamond Pro! I had several bids and from the first point of contact Leo was professional and spot on responsive. He stood out in front of all other bids. Was not the cheapest but so glad I chose them because I feel like I got the best deal. He was detailed about what service would be provided. His pricing was very fair and affordable. Our roof looks fantastic. Everything was cleaned to perfection. Our cleaner showed up exactly as scheduled The clean up was beyond my expectation. I think I got a free window cleaning In there somewhere 馃榾 I will definitely use them again.
