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.

Wow! This was a find! We were looking for someone to power clean our deck, awnings and several pieces of woebegone furniture. Heard from J'B within minutes of my Thumbtack inquiry and within an hour, they were out to give a bid -- we were so impressed that we went no further, just said yes! The job itself was outstanding. Beyond the powerwashing, J'B and his two companions ran a knife or something between each piece of wood on the deck, removing all the gunk. The wooden bench looks new again, well, almost -- now I have ambition to oil it. The four awnings were washed and scrubbed, literally. We should have had this done earlier. And so glad we found J'B. Paid $590 -- they arrived at 8:40 am and left around 2:10 pm. We had one other bid, which was about $200 higher, so besides the qualty of the job we felt we really got value!

Aaron has been cleaning our windows inside and out for many years now. He always greets you with a big smile, and is eager to start working, and when the job is done, my windows sparkle. Now, he offers power washing, which I took advantage of this time around. We have a very steep roof, and he brought along is rock climbing gear to maneuver his way around while holding the power washer nozzle to remove all the grime and moss that had accumulated on it over the past few years. I was so impressed with the outcome that I had him clean a concrete pad that our hot tub sits on. I would highly recommend him for the skill, experience, and professionalism that he brings to the job. Aaron makes it easy to schedule an appointment on his online website.

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.
