Jeff did a great job for us. We hired him to clean and inspect our chimney and fireplace.  We thought we might have to spend a few thousand dollars on a liner, but he found that our chimney was in good shape overall, and our issues could be fixed with repairs that were much less costly.  Besides the cleaning, he ended up replacing a broken damper and strengthening areas of weak mortar. He also found seals on other roof vents that were either cracked or loose.  He repaired/replaced those, stopping a major leak potential in our attic.   Jeff also   cleared off other debris around the roof and gutters.  Overall, he did great work at a price better than we anticipated.

Minor water damage on our bathroom ceiling indicated a roof leak. We determined the water was coming in through the roof vent pipe and that the pipe collar needed replacing. Thomas responded quickly to my request for a bid with what I felt was a fair price for the work. We arranged a time for him to come to the house. Before the appointed time, he sent a msg letting us know he was on his way. Having been in commercial project mgmnt for 15 yrs, I am familiar with how to correctly flash and seal roof stack pipes. Thomas removed the damaged collar, added a water/ice shield, replaced shingles were needed, and applied sealant where needed. He worked quickly and cleanly. Thomas has thorough knowledge of roofing systems and applications and is clearly experienced in repairing roofs. His business model is to focus on roof inspections and repairs. He does not install roofs. This allows him to charge a reasonable fee that businesses that are primarily roof installation companies are unable to do - there is a cost to take a person of an installation crew in order to do a small roof repair. The price for the work was in line with what I felt was fair. Highly recommend Thomas with Nova CS for roof repairs and/inspections.

We bought a house a few months ago (our first) and were told upon inspection that the roof was missing a shingle and had some nail heads popping up. We reached out to various roofers, and Mr. Harriford came the most recommended and had the most reasonable price. When he arrived, he got to work quickly and when finished showed me pictures of the work he had done, which included caulking a few spaces he felt needed it and securing a shingle that was ready to come off. He did these extra things without any extra charge. I also had asked for an estimate on the life of the roof and a rough estimate on the cost to replace it. The roof is 22 years old, and Mr. Harriford could have easily said it was on its last leg and I would have believed him, however he said he thinks it has 2-5 years left. With contractors it can be hard to discern whether they’re telling you what you actually need, or whether they’re just hoping for extra work. I greatly appreciate Mr. Harriford honesty, and genuinely believe he is looking out for his customers. I highly recommend him and will definitely be using him in the future when we do need a new roof.

My roof was very old and faded, so I contacted a couple of companies to get quotes. EBRR quoted less than the other company, and I was impressed by their representative (Ed) who gave us the estimate. We did not wait much at all, the work was done in just one day. I watched when they finished and they really looked all over for garbage and pieces of roof that had fallen. It was spotless when they had left. The roof looks great and Ed came back shortly after to check it out and see if I had any questions. The front office was always polite when I called, so I recommend you give them a try.

Chris was beyond excellent, he came prepared and on time. He was constantly communicative given the issues that we experienced on March 2, 2018, (great wind storm of 2018). He met with me the Monday after that storm and listened to all my questions, which were written down, he was calm and patient, even when I told him that I was getting a total of three roof replacement quotes. The value, responsive, and professionalism guarantees that we will hire Window Source of VA for future projects. Our new roof looks great! We couldn't even tell that they were there. The property looked pristine and we are very pleased customers. I would recommend this company to anyone looking to have quality work done. From the office, management, and employees they are top notch! Thank you all for your outstanding work!

Baker Brothers did a fantastic job on our siding. A storm came through recently and pulled our siding off of the roof in three places. Shaun and Ernie from Baker Brothers were a pleasure to work with. They fixed the siding and it looks amazing. We're very happy with the courtesy and professionalism that Baker Brothers provided.

The experience of hiring NOVA Exteriors, working with the appraiser, and having the roof done quickly and as promised was a seamless experience. After many weeks of rain, the roofers were able to install the new roof quickly, and it looks great! We also have peace of mind knowing that their work is guaranteed, too. Will definitely check with NOVA Exteriors again for future remodeling projects.

I hired Mr. Lantz to clean the windows and gutters on my 3 story townhouse. The work he did was unparalleled. He worked quickly and efficiently, very thorough, cutting no corners although I imagine it could have been a tough job to do with the height of the house and tilt of the roof! The cost was affordable, he was courteous and professional. I could not be more satisfied with the work Mr. Lantz did for me.

Erick and Melvin are true professionals. We hired them to install a gutter on the side of our porch roof. Not only was Erick responsive via text and flexible on his availability to do the project around our schedule, they arrived early on the date we planned, ready with all their materials, and completed the project quickly and professionally, answering all my questions throughout. The result was a beautifully completed project that we are more than satisfied with - we couldn't be happier to have chosen them. They were the most reasonably priced, most responsive, and professional throughout the entire experience. We'll be hiring them again for sure! Thank you Erick and Melvin!

Excellent work and a reasonable price. When looking over my house’s roof the pro even noticed my shed needed new roofing, which I was actually fielding price quotes for at the same time as I thought a separate company was needed for shed repair, gave me a significantly better price then the shed repair companies, and got the job done at the exact same time they repaired my roof. Will work with them again in the future.

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 is a standing seam metal roof?

A standing seam metal roof may be a strong, durable, safe choice when you’re considering metal roofing installation options. A standing seam refers to the raised seam where the sheet metal roofing panels join. Traditionally, shingles and roof panels lie flush to the roof, making them more prone to rust or penetration by water at their seams. In a standing seam metal roof, the raised (or standing) seams run vertically from the roof ridge to the eaves, with no horizontal seams. In addition, the fasteners joining the metal panels together are concealed, providing even fewer opportunities for water or moisture to build up. The cost to install a standing seam metal roof will depend on the type of metal you select, the size of your roof, and the cost of roofing labor in your region. Materials will play a major role in your metal roofing installation costs. If you select standard galvanized steel, the cost per square (100 square feet) might be in the $150-$300 range, while a high-end choice such as copper or zinc could be between $1,000 and $1,500 per square. Here is one example of cost:   

  • Standing seam metal roof: $300 per square to start, including materials and labor.
    • A 30-square roof could cost $9,000 or more.

Can a metal roof be installed over shingles?

Metal roofs are durable, environmentally friendly, safe and budget-friendly. If you’re considering an update, metal roofing installation doesn’t have to mean completely removing your old roof. In many cases, metal roofing can be installed over your existing shingles. Research building codes in your state, as many require that after two roofs have been installed, all roofing materials must be completely removed before a third roof can be put on. This protects your home’s structural integrity and your family’s safety. Carefully read contractor reviews and choose someone with extensive experience with metal roofing installation. One concern when installing metal over shingles is that over time, condensation can build on the shingles and cause the metal to rust. This will lead to rust around the panels, making them more likely to come loose in a storm. Nationally, the average cost for metal roofing installation ranges from $6,000 to $20,000. The wide price range represents different roof sizes, different types of metal, and the cost of labor in different parts of the country — and can also include the cost of removing an old shingle roof prior to installing the metal. As a line item, the average cost of removing an old roof to prepare for installing a new roof, plus adding new roof decking, costs on average about $45-$75 per square (the pro roofer’s term for 100 square feet), depending on the pitch of the roof. Always make sure you have a clearly written contract and a warranty on both the labor and the metal.
