Gabe had quite a drive - over an hour- to even get to our house! He arrived right in time and assessed what he was going to do with our gutters over-spilling and not draining properly. The problem had to do with damaged leaf traps which were causing huge blockages in several different locations around the roof edges. He called us out to view the waterfalls that were occurring after cleaning out the gutters. It was amazing to see how long the water just kept gushing out, and this was a sunny, dry day! We are good to go, he kept his price very affordable so we can look forward to having him back in spring to have him remove the moss from our roof tiles, and wash all of our windows. Gabe is dependable, knowledgable, kind, and confident. He has excellent work ethics and is very proud to help people as he enjoys meeting folks who need his services. You will love Gabe - my husband and I surely do! Good luck Gabe, that stack of cards won't last long- you will get many referrals from us!! Bob & Jill Salmons El Dorado Hills

Do yourself a favor & hire Jon. We recently moved to a house with a massively overgrown tree. Jon & his team tackled the project in a few short hours and got rid of the problem tree, cleared our rain gutters & cleaned up all the debris from the work. They were punctual & professional, showed up on time & quickly worked to throughout the project. From start to finish I couldn't have asked for more & they were extremely competitive in pricing. I would definitely recommend Jon to friends & family needing tree removal or gutter cleaning services.

I asked to patch a leak on the roof. Jose came up in the attic with me looked at the leak from below and patched it. I also got a great fast estimate for laying another layer on the roof, as I only have the first layer, after all my roof is about 30 years old, it is about time to do. He pointed out that the previous roofer didn't do an overhang and this might also cause leaks. I haven't had it rain yet, but so far I am very happy with the service and quote.

We unexpectedly needed an electrician on a Sunday, and Rafael was not only the first to respond, he was willing to come over immediately. What we thought would be a simple job turned out to be much more than that, and even entailed removing some stubborn exterior brick work (long story). Boy, were we lucky to find Rafael. He is skilled in many areas, and he was exactly who we needed for our job. He did great work and we couldn't be happier. We'll definitely use him again!

Frank did an excellent job of doing a wet patch on my chimney to fix a leaky roof into my cast iron stove in the family room. He was on time and went and bought all the needed material n fixed the roof n painted the rusting chimney within less than 2 hours. I will hire him again!

It has been great to work with Sustainable Roofing Solutions. They did a great job repairing and re-vitalizing my wood shake roof. I prefer the look of shake to composite. Rather than spend three times as much on a new roof Sustainable made my existing roof as good as new. I've had people stop by and ask me who put on my new roof. It has been eight years now, the roof looked great for the first five years; it still looks tidy. I've never had had a single problem. I have seen other roof restorations in my neighborhood, none of them have stood the test of time like my roof. In addition to the roofing, Sustainable repaired existing dry rot and replaced some siding. All of the work was quality. Kasra, the owner, even comes by my house now and then and checks on the roof. My complete exterior restoration and paint project is due soon, Sustainable Roofing Solutions will be my contractor.

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.
