Our organization had a large number of trees and debris that needed to be hauled away and cut down. The appropriate equipment was out on site and Ed had the project done in record time since it consisted of about 2.5 acres that needed to be cleared with brush needing to be removed as well. Scope of work was removal of trees/brush and debris and also leveling the land to make sure there was the right drainage. Project took 4 days to be completed and I couldn't be more happy with the service and the customer service that I always received since I did call Ed in the late evening and he always made a point to answer and return calls. Will be referring to our other commercial clients!!

After meeting with four different general contractors, Mr. Marvin Guzman with Baiza Construction, Inc showed his best attitude to take part on a serious complete home improvement we had for our 1956 home. He didn't only provided a quick estimate, But time frame to complete and over all his price. My project was based on a full 2 bathrooms remodeling, plaster walls removal/replacement, insulation, plumbing, electrical, kitchen remodeling and about 2500 square foot of hardwood floor installation. My best recommendation to future hires and families of his great quality work. My contract worth 86k were put on the best hands.

I hired Norm to pressure wash my siding and deck that were covered with algae. He came on time, completed the job and without my asking, washed another small deck and even climbed on my roof to get the last bits of green slime. He was friendly but professional and returned my phone call with in hours. I have him scheduled for another job next week.

Christian and his team were fantastic! We needed our basement re-finished after some flooding with the recent rains. They responded promptly with a quote and came in to do the demo before the waterproofing company installed a sump pump. They were flexible when we ran into some delays with the waterproofing, and showed up when we were ready to start. They provided creative solutions for how to re-finish the space to make it even more functional than before. Communication with the team was great, quality workmanship, and all at a great value. We'll definitely look to them again for any future work. Thank you!!

Roof needed maintenance and COVE was able to schedule me in for an estimate the next day and they were able to get the job done at the same time! Anthony was really nice and took pictures before and after the repairs and also gave me his professional opinion on the roof and when I should anticipate needing to replace it.

Balcony ceiling upgrade/repair project. Eric and Bob are both highly skilled and motivated. They were able to resolve very difficult issues that most contractors would likely walk away from. They are a very polite, efficient and professional. The result was better than I anticipated. The final design that they came up with is not only durable and attractive it provides added support and protection to the roof of my building. I would definitely recommend them to others or hire them myself for another project.

Martin did a great job thoroughly explaining pricing and what work was to be done. Showed up on time and did the work in a professional manner. While he was asked to clean out the gutters he took the liberty of removing tree debris from roof and bagging and taking with him gutter debris. Would hire without hesitation in the future.

Tom did a great job on some needed roof repairs at a reasonable price for a DC rowhouse. He is also knowledgeable about a wide range of other household jobs and was able to fix and help with several things around the house. Communication is not his strongest point as he has missed appointments without calling but if you can be patient its definitely worth it to have him help!

Had these guys come out to remove the stains on our roof and also to powerwash our siding. They did a great job! They were better priced than my regular contractor even with a bit of a price break from him. AND I came out to ask the gentleman (Sterling) whether I could pay him a little extra and he could powerwash our porch furniture for me, and he said, "OK, I do it for free"! THAT is customer service! Cost to clean our entire roof and treat w/mildewcide, (single family home) was $650.00 Exterior house wash and wax was $308.00

Ivan and his crew have done encompassing work on my home, beginning with an extensive interior remodel in 2005 and continuing through 2017 with smaller jobs such as hot water heater replacement, garage roof repairs, garbage disposal replacement, and ongoing updates or repairs that are part of living in an older home (I have a 1930s-era row house in NW DC). I've recommended Genesis to many friends, and they've all had similar experiences: Responsiveness, sets clear expectations on what he'll do and when, high quality workmanship, and fair prices. That's also his reputation with others in my neighborhood who have contracted with him for decks and kitchen remodels and more.

These 2 young gentlemen were able to quickly remove some debris from my yard and take it down to the dump. They also informed me they cleaned gutters so I was able to have them grab and bag the leaves from my roof.

Q & A

Answers to commonly asked questions from the experts on Thumbtack.

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.

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.

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.

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.
