"We live in a house that has a flat roof. It's also down a hill so you look down at my roof as you approachmy home. That's why the appearance is so important to us. I had several "flat roof experts" come look at the job and walk away. Bill (the son) didn't even blink. He immediately gave us the confidence needed to know these guys are the real deal. They took two layers of tar & gravel roof off my house and installed a high tech membrane and insulation. They had to drop the old roof down to the ground then hump it up the stairs into the dumpster. They came with 9 guys, Antonio was the crew chief. The nicest guys. And when they left, my property looked clean, without a single shrub or flower out of place. And the new roof is beautiful. Bill (the father) was here to supervise and really added to our confidence and satisfaction. I don't write a lot of reviews, but these guys deserve the shout out."

"Kadre came on time to provide me with an estimate for replacing a skylight. The estimate was very thorough. He showed me pictures and videos of what he saw while on my roof and took the time to explain everything from why the skylight was leaking, the steps he would take to complete the job as well as the materials he would be using. The quote he gave me was very reasonable. Also while he was on the roof he recommended fixing two gutters ( which I already new I had to get fixed) and was able to give me an honest price on those as well. When it came time to do the repair, he came four days after the estimate (on a Sunday because it worked best for me) and again was right on time. The whole job of replacing the skylight and fixing the gutters only took a few hours. They cleaned up any debris and again reviewed the job he did with pictures and video from the roof ( which is a big help since I don’t like going on the roof). Before leaving I was made aware that he also does siding. He gave me an on the spot estimate to do that job as well and I am already sure that I will be using him for that in the spring. I only write reviews when I have an absolutely terrible experience to warn others or in this case when the company is extraordinary and goes above and beyond. I can without hesitation recommend this company"

"Owner Deniz Aksan is very professional and was a pleasure to work with. He showed up timely on the day promised and the job was done quickly and every detail was accounted for. After they left everything was cleaned up and besides the new roof and garage caps it was as if they were never there - everything was left spic and span. i couldn't have asked for better service, but the quality of the work performed and life-time guarantee on the roof just was icing on the cake. I would hire him again in a heartbeat."

"All phase construction is excellent. They came the same day that I asked for the quote. They started the work the next day and the prices seem reasonable. Tony pointed out potential problems and worked with me to fix it. I would highly recommend their services for anyone that needs a repair to a roof or chimney."
