"Bill Taylor, the President of the company, carefully surveyed the condition of the roof. His detailed, clear estimate addressed all of my concerns. The crew assigned to the project was efficient and courteous. The company is GAF certified, ensuring the warranty will be honored. I highly recommend Four Seasons Roofing."

"They did a good job at the price they stated and were very professional. It was a small repair job. But I am hoping it will last and the roof would not need attention for a few more years."

"I have used this company before for my roof and they are excellent. Dimitri is very professional, knowledgeable and very polite. If you want quality work this company will do a quality job. I needed several things done around the house and Dimitri did them the same day that he gave me the estimate. I look forward to using Onyx Home Construction again."

"Needed a difficult (cedar shake) roof replacement on very short notice. Deniz (owner of business) was amazing to work with. No complaints at all. He was great with communication, clarity, quick to respond, and his pricing is great. Everything that was planned for happened the way he said. Crew came in on time, worked incredibly hard and fast, and job was done in a day. It also speaks volumes that as the owner of the business he is not only onsite for the job but actively helping out the crew. Couldn’t ask for a better experience and couldn’t recommend Deniz and Non Stop Home Improvements enough. Will be using them going forward and recommending them to anyone in need."

"We have been having a problem with pigeons hanging around all day on/under our solar panels. I originally had a handyman who was going to install mesh around the edges of the panels and yesterday (the day he was supposed to come) found out he didn't have insurance/license so I canceled. I then went into a Zoom meeting and heard the darn pigeons cooing and fluttering all over the roof and got so upset. I came to Angi and found Best Choice Roofing (aka Best Way) - he called me back right away and in less than an hour he was here. The first thing he did was hand me his business card with his License # on it. Very professional. He got up on the roof, then in a few minutes came down and gave me an estimate. Once I accepted, he called his team to assist and he started on the roof. They were super clean - blew out my gutters, blew everything out from under the solar panels, and made sure to blow the porch and front of my house to remove any debris. I had peace of mind that they were licensed and insured. Today I am happy to announce, I have not heard ONE PIGEON! I know this company usually does more like roofing and gutter-type projects, but I will be letting any of my neighbors with solar panels/pigeons know who to call. Great crew. Thanks so much!"
