We used Star Cleaning for power washing of house, porches and stone walkways. Looked brand new when finished. Excellent job! Also, they washed interior and exterior windows - Beautiful job. I have used many window washers and they were by far the best. We will only use them in the future.

I really appreciated the transparency and honesty displayed by Baker Brothers. I was having a leak in my house, but it turns out it was the gutters and not the roof - they didn't try to sell me on the roof or a huge patch job. They suggested some preventative measures and some areas where I had to get gutters replaced. Their pricing was fair, and their tech showed me pictures and talked me through their assessment and next steps. I would recommend Baker Bros again!

I first hired Marvin to paint and frame 44 newly installed wooden windows in my historic row home. Because I was so impressed with his professionalism and superb quality of work, I contracted him for additional services including porcelain tile installation, surfacing and reframing a roof deck, and completing the finishes of a previous contractor. If you want to hire a competent company that takes price in their work and delivers high quality services, Baiza Construction Inc. should be your choice.

I call on Bill to do all my home improvement projects. He's professional, knowledgeable, experienced, with reasonable pricing and a very easy going nature - - all of which makes him easy to work with. Bill provided quality work on our interior painting, exterior wood repair, roof repairs, tile work, and paver patio installation. He also built us a shed, and consistently shows us his helpfulness & resourcefulness.

Superior contractors were on time, they did a roof repair instead of a new roof as others tried to sell me. Superior informed me that no new roof was needed. AN HONEST contractor with quality workmanship!! Thank you Superior! I highy recommend them. I would definitely use their services again.

Mike and his team did a great job. They met with me, gave me a quote right away based off his professional experience and my desired material. He was able to begin and complete the project within a week. He honored his quote to the very end of the project and was a pleasure to work with all around. My roof looks beautiful and every step of the way I reviewed his team's progress and was extremely satisfied. I don't know how he can do this project at such an affordable price, but if not, I wouldn't have such a wonderful roof today. Mike is easy to work with, very responsive on the phone and I would hire him again. If you can find someone who is beating his prices, they are cutting corners somewhere.

    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.
