"Customer service was top of the line. They worked everything out with the insurance adjuster and Roof was replaced instead of repaired. It was a pretty steep pitch and had quite a bit of hidden damage under the shingles, but they got the roof replaced in two days. Fantastic customer service and a great roof!"

"Great! Our flat roof was pooling water and our traditional part of the roof had no ventilation. Eugene's crew came to complete repairs. The crew of 4 arrived right on time at 8 am, they began disassembling part of the roof while materials arrived from Eugene, the owner. The worked all day and were done around 3:30 pm. I asked if I could go on the roof and see what they did and Florindo, the lead of the crew, gave me the run through of what they did. Then they cleaned up the whole job and left with the waste for the day. The crew was great and Eugene went out of his way to make sure the job was done right, he came and inspected the roof work about after the crew left."

"I have nothing but great things to say about Sam and his teams. They recently completed a challenging roof project for our property and from start to finish (bidding thru clean up) they did a great job. Communication was clear and timely, workers were friendly and thorough, they managed unexpected challenges well and completed the work on schedule. This is not the experience I’ve had with other roofing companies, so I highly recommend Sam and Forever Roofing."

"Curtis, the second generation of this company was very professional and thorough in our estimating searches. The main reason we went with them one it’s family owned too. It’s local and three gave us the best price out of the five quotes that we got. The whole project from start to finish was done very well by the company and his workers. Every day when they were done with work, they made sure to run a magnet through the driveway so we wouldn’t get a flat tire on our cars. The team worked very hard and was able to wrap up our whole roof project within a week even during crummy weather. If you are in need of a roof replacement, put DHT roofing at the top of your list we would hire them over and over again for how well they made this project and smooth they made this project go."

"The company sent before and after pictures of the work and was very thorough on what work needed to be performed. They have scheduled the larger roof work for a day without rain since a temporary fix is in place."

"We needed a new roof including new sheeting. Our roof was a 23 year old composite roof with 3/8" sheeting. We received 3 bids from different roofing companies. All of the bids came in within a few hundred dollars of each other. We decided to go with A Better Roofing Company because of reviews, their history in the area dating back to 1991, and the professionalism of Daniel who wrote up the estimate. We received the estimate in October 2018 and the job was completed in December 2018. Scheduling was a difficult because of the rainy days. The crew started on a friday and finished on sunday. The crew worked right thru until the job was done. When i had my extimate done i had choosen white flashing around the roof to match the facia board. The crew mistakenly installed dark flashing that matched the black roof we choose. When I did the walk through after the job was completed with Michael right before Christmas i pointed that out. He immediately said they would come out and replace it with the correct flashing. Since Christmas was a few days away I related to Michael that they could come out anytime after Christmas, no hurry. The next day when i got home from work it was all replaced. That was being responsive! The roof is beautiful and solid. I would recommend A Better Roofing Company to everyone."

"I think this company is excellent. My review is way overdue, so apologies there. But when my flat roof was leaking water into my hallway, they, unlike other roofing companies I contacted, told me they would work in an immediate temporary repair. True enough, by that evening, the repair was done. The company finished their current job and then squeezed in my project after working it out with their next customer. So within I believe a week of my emergency, I had a new roof on. Truly great people to work with, from explaining the bid to me and communicating on daily progress. I have 4 different roof levels and have replaced the others at various points using 2 other roofing companies. Three Trees is the only roofing company I would hire again. Oh, and also amazing clean-up, as well as cleaning of my other roof levels!"

"I had several attic vents that had been damaged during careless roof cleaning. Hector gave me the best price and was able to do the work the same day. The work was great, and he showed me some things that needed attention (but did not try to scare me into immediate repairs). I am definitely going to hire him again for future roof work."

"Very professional and timely bid process. Aside from roofing our home, they also had to completely remove and replace our rotted flat roof on garage. They were fast, cleaned up well, and were always very responsive through the process. I would highly recommend them."
