The quote was competitive. The team was fantastic. Delivered materials the day prior and showed up promptly to begin work. Everything went incredibly smooth--the crew finished by late afternoon.

We are so glad we went with them over other options in Frederick. Looking forward to not needing to replace this roof again!

Bottom line up front: Impact Roofing is not a company that takes hands-on pride of their work. They…read morewill send a team of people who barely speak English to do your project with no supervision. The company will go hands-off as soon as they get your deposit. I almost never write bad Yelp reviews and I have been sitting on writing this review for a while but I had to because I am still so upset with the quality of service. When giving me my estimate, they sent a real professional to actually survey the property, go up on the roof, take measurements, etc. I had a really good feeling about the company. However, the person who gave me the estimate quit the company and I was reassigned to someone else who never physically came by to see the property. On the day of the installation, the team that they sent had no familiarity with the specifics of the project (which was attic insulation, gutter installation and rain barrel installation). I had to explain everything to them all over again, like they'd never heard of it before. It didn't help that they didn't really speak English and I had to show them what a rain barrel was with hand gestures. The workers installed my backyard rain barrel backwards, and my front yard rain barrel upside down. They took bricks from another part of my yard to mount my rain barrel without asking. The worst part by far: One of the workers, without asking, cut down my Virginia creeper plant that I had been growing and training for three years. It covered the front of my house and attracted birds and butterflies in the spring. Now it's destroyed. There was literally no reason to do this, he didn't ask for permission or anything (he said "it's poison!" when I asked why he did it; it's not, it's a harmless native plant). My house used to be unique, now it looks like every other house on the block. This last offense was intolerable, I called the company and demanded they sent someone down. They ultimately discounted the project by $2600, which was fine but did not compensate me for my loss. This was the first time any supervisor actually came to the property. It was clear the supervisor didn't know the workers at all, and he couldn't communicate with them any better than I could. The management had no interest in coming by to check work after it was complete, either. I had to reach out to them to request that they do so. They were perfectly content to just let their workers do it and leave for the day. Ultimately, they did the job that was on the contract, hence the two stars: they insulated my attic, installed gutters, and installed rain barrels. But everything else was a terrible experience. I wish I could undo hiring them in the first place.

With regards to the heating of our home, the windows were no better than screens. I reached out, looking for windows and installers. I had a few people come in and estimate the job. None of them impressed me until Greg from Windows on Washington came over. He walked me through several options and explained how the windows they used were manufactured and why. Windows on Washington got the job. My windows and my doors were being manufactured. So they sent out a wonderful gentleman to get the final accurate measurements. Great guy. After that, communication was wonderful as were were assessed of the stage we were in. This included when we got the email and calls explaining that, since we were on a higher floor, they needed to bring in some equipment to lift the new doors up to our balcony. No surprises. Installation day was amazing as Joon and his team came in, got everything into place, and cleaned up the areas to better than when they got here. Joon then went over the features on our windows and even explained how we get to and clean the outsides of the glass. Wonderful man and amazing team. Since then, we have gotten copies of our warranty and the guarantees. And the company has reached out twice to ask if we have any questions and to ensure that we are happy with our windows. We are. We are very happy with our windows. Almost as happy as we are with the people who got them into our home.

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.

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!
