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!

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.

This company wants your money and won't let you review the contract!…read more I never do this but I was so puzzled by the behavior of the sales man. Olani seemed very knowledgable and took a very long time to do his presentation. As any good sales person he was a little pushy but we get it he wants to sell. At the end of the presentation we had a few reservations about the fit of the product and I could see he started to get less patient and less polite. Later in the day me an my husband decided to pull the trigger and contacted him so he can send us the contract to review for signature. But he said he could not send a contract until he had a card or a check number. My husband told him that he needed to review the contract before because that is what any normal person would do before handing any money. Olani became very short and then proceeded to hang up the phone! Horrible manners from someone who claims to work for a company with stellar reviews which actually is not even true!

They were super responsive anytime I reached out with questions. Emails and calls were returned quickly, which made the whole process feel smooth and stress-free. They also got someone out pretty fast to measure the windows, so things kept moving without delays. I ordered 10 windows for my townhouse at the end of February, and everything stayed on track. The windows came in April, and installation was set up for the very next week, exactly how they said it would go. The install team (two guys, led by the amazing Mark) was awesome, very professional, worked efficiently, and took the time to protect my floors and furniture. They cleaned up as they went, which I definitely appreciated. Scott, the owner, stayed in touch throughout the day of installation and honestly throughout the whole process. I had a couple of window and sash issues but Scott was amazing and the kind of communication and follow-through really stood out. Overall, I couldn't be happier with the experience. They did exactly what they said they would do, and the customer service was top-notch. I'd definitely recommend ZEN Windows to anyone. It really was a calm, "ZEN-like" experience. Haha!!

When he discovered a problem that was not foreseen by the estimator he had to run out to get a part but came back promptly and finished the job on schedule. Although this specific element was not included in the original estimate, Jose installed it without fuss and did not charge for the part or his extra labor. Where can you find that kind of responsibility these days? I would never call anyone but Marshall!

They came out and replaced the vent and associated shingles. Great fix! Now, 25 years after moving into this as a new house, I needed a new roof. I got two estimates, one from Marshall. Marshall's representative, Doug, was so thorough and professional in his reprensentation to me and offered a solution re moviing the attic exhaust fan closer to the eave and keeping the ridge vent. The other estimator suggested removing the ridge vent. I wasn't comfortable not having a ridge vent. I again went with Marshall. It was a two day job. They dedicated a more than sufficient crew to the job. The guys were so attentive to protecting against falling shingles as they were stripped from the roof. In short, they did an excellent job! I had absolutely nothing to be concerned about with Marshall's professionalism as a company. And, there cost was lower than my other bid. I only got two bids as my past experience with Marshall and with Doug's representation made it a no-brainer! If you need a roof, go with Marshall.
