"Absolutely an awesome team to work with. Eugene was the point of contact from start to finish. Complete work was done in four days for roofing and gutters. The team cleaned the site daily and made sure everything was protected prior to work start and delivery. Eugene also came out a week after the work was done (and after a day of heavy rain) to check and see if I was still satisfied with the work. Their five star rating is true to our experience. Highly recommend this team for your roofing needs!"

"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."

"We were very pleased with the tear-off and new roof done by Forever Roofing on our house in North Seattle in mid-June of 2020. The estimator Sam contacted us the next day after I left a message and came by within several days and gave us what I felt was a reasonable estimate that included several other requests including removal of a no-longer used chimney and replacing about 20 feet of facial board that was too high for me to replace safely. The crew was great. They were able to utilize the one corner of the house that didn't have plantings for their work area. They completed the job in two days and the gutters were installed on the third day. They were very careful in their clean-up. I would not hesitate to recommend Forever Roofing for their response time and the quality of the workmanship."

"We just had our full roof replaced by Roof4Life, and we could not be happier. Professional work is done in a timely manner. Huge improvement from our old roof. The new waterproofing looks great. Good roof for a good price, and the crew did a great job."

"Kelly and his team at KSR Roofing was able to figure out my issue quickly and resolve it as soon as weather permitted. I have a flat roof modern construction house which is difficult to assess where the leaking is coming from. I had many quotes for full roof replacement. After spending some time figuring out my problem, KSR was able to resolve my problem significantly less expensive than other quotes. KSR has an extremely experienced and talented team. They also offer good value and incredible customer service."
