Jon just finished replacing the vents on my roof and cleaning my gutters. He was quick, professional and very trustworthy. I really liked that he took pictures of everything before and after so I could see the work close up. I'm not about to climb up on the second story roof! I would recommend him to anyone.

Cesar came by the next day after I requested a quote to replace my roof ridge caps and gave me a very competitive price and included painting the metal fittings on the roof, cleaning out the gutters as well. He also pointed out examples of non-ideal work by the previous roofers that he fixed as well. On the day of the job, he and his crew arrived on time, completed the job and cleaned up after themselves. I'm very satisfied with the quality of the work, especially with the promptness of his replies to my messages. I'd definitely hire him again for any roof work that I have.

Pros: Did a good job cleaning windows (5 stars), even the skylight on the roof that is pretty hard to get to Personable/friendly Easy to schedule Cons: Major disconnect on the price. As one other reviewer pointed out, they count window panes as windows and Maria did not say anything on the phone or asked any questions as I described the job to her. As the result, the actual cost was much higher than what was quoted. Still a reasonable price, but certainly not cheap.

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.

This was a small job, terminating a special roof mounted-fan. I gave Rafael my requirements for a switch and a thermostat cut-off, and after some discussion about the difficulties of running in-wall wiring behind the wooden panel wall, suggested a way to the wires which was code compliant and far less obtrusive after painting than I first feared. He shopped around at several supply stores to find just the right parts for the project. He and his assistant did a great job as you can see from the pictures! He was also very prompt.

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!

We had Sustainable Roofing inspect our asphalt shingle roof after last season’s rains when a leak developed. Kasra, the owner of the company, charged a reasonable fee and did a thorough inspection of the roof and even the siding and rest of our exterior. He gave us an informative verbal report on a good deal of what was going on with the exterior with special focus on the leak issue. He also showed us digital photographs to support the education and ensuing consultation with his recommendations. He also gave us a written estimate sheet. He put no pressure on us and left with a smile. We already had another estimate but it was an easy choice to make because everything he presented and explained for us seemed 100% scientific and very upfront. At the same time, it all came at a reasonable price that did not seem misleading whatsoever. The price was higher than our first estimate but it was obvious it was a much more thorough service; taking care of the immediate leak as well as doing most of the pending maintenance needed that we had neglected for so long. About two weeks later, Kasra came out himself with an assistant came for the first day and got the work started and set up for the finish a couple of days later. It really felt like we got more than what we paid for because they did all of the right procedures, stopped the leak and gave us peace of mind for the years ahead. At my request, I even received a follow up email with photos of the work done and that really nailed it there because my feelings about the great service we had received, just felt totally confirmed. Thank you SRS!

Martin responded promptly and came out to evaluate the problem. Very punctual and professional. He found no problems with the roof, so no work was done. I'll definitely have him in mind for future projects.

    Tony & friends came over right on time and got the job done well. Tony also brought a friend over the next day to give me a proposal on painting the place (which I'm going to take!) and while they were there they all helped me carry in a couch, chairs, and several other heavy items - refusing to be compensated for the extra work. Great guys! Thanks!

      I met with at least 3 different contractors and I'm glad that I went with World Exteriors. Overall, I was satisfied with their experience, work, professionalism and detailed communication.The new gutters definitely made the house look nicer. The work itself was very neat and well-done. I would recommend this company to anyone. Chris and his installer was absolute best!

      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.
