    David provided an excellent service to an incredibly complex front porch roof and gutter issue…read morecaused by a nest of squirrels living rent-free for decades. We bought a century-old rowhome in D.C. and didn't realize we also inherited a family of squirrels that ferociously dug into our front porch beam. We've gotten several quotes in the past two years where roofers and siding companies chalked it up as "this is going to cost you a lot of money and it's just not worth it." We finally decided to prioritize fixing this problem and got three quotes. I got two other quotes, and one was really expensive (due to different material cost) and the second one was comparatively the same. I trusted David's expertise because he was referred by my friend who highly recommended him (David fixed my friend's leaky roof issue nearby); and David didn't give me a run-around answer with the problem I had raised. When I finally decided to start on the project, David's team was ready to go. I wanted David to fix three big areas: 1) trimboard/beam; 2) gutter; and 3) front porch ceiling. David's team took photos throughout the process, identified that the front porch trim board didn't actually have a beam inside, so the squirrels lived in this hollow space filled with mulch and tree branches. They quickly gave me an estimate of the additional cost to add a beam and worked extremely hard to fixing the front porch roof area. They were done within a day and a half. I'm super pleased with David's craftsmanship. David went above and beyond my expectations, fixing a beautiful antique crown moulding that the squirrels chewed up, and making it look like new. I am so relieved to know this problem is now fixed and the squirrels have no way of getting back into the roof. Everything is sealed and properly done. Please protect David at all cost. He is a 10/10.

RESPONSIVENESS - very fast, very responsive, very professional. A tad too frequent, but apparently roof repair is a competitive business. INSPECTION - scheduled and conducted efficiently; exceptionally thorough inspection report (David). COST - in line with all other quotes, which are apparently driven by the insurance estimate. Green Oak differentiation included owner interaction, master roofer certification, 5 star rating, excellent warranty, professional documentation and workflow management. WORK - scheduled efficiently, material arrived on time the day before, crew arrived on time the day of, work was conscientious and completed in 3/4 day (townhome), clean-up (including loose nail hunt) was impressively thorough. AFTER - received certificate of completion in a timely manner, along with photo record of repaired roof. Not being a roofer, it's difficult to assess the integrity of the new roof & shingles, however the end result appears clean and professional. Suspect the new, high-quality roof will increase the townhome value and/or decrease time to sell based on the high-quality products used and overall curb appeal of the work. Overall quite satisfied with Green Oak. Recommend.

    After a large javelin-sized branch impaled our ~5 year-old roof, all the way through the shingles,…read moresheathing, and paper, my insurance company asked me to get a 3rd party quote to compare to their assessor's. I reached out to Green Oak after searching on Yelp (s/o), and was extremely glad I did. Brian H. took me through the process from start to finish, including an insightful explanation of the insurance claim process. The free estimate happened within a few days and ended up being lower than the insurance-assessed quote. He recommended a roof "tune up" as part of the package without pushing or trying to upsell me for more, which i really appreciated. He also accommodated my inquiry of adding on the installation of a bathroom exhaust vent cap, which was missing when we moved in. After being extremely reasonable on pricing and lighting-fast on responses, they scheduled and completed the work the day after signing. The team was efficient and respectful, with a huge attention to detail. TL;DR - Highly recommend giving Brian and Green Oak Exteriors a shot to help fix your home exterior issues, especially when you are in a bind with your insurance company!
