What Our Customers Are Saying About Us

Abe and crew replaced our roof. They came recommended by my partner's coworker and we extend the recommendation. They were not only professional and easy to work with, they checked and followed up to make sure everything was perfect (was close to it, but they sent someone back to paint a few loose siding tiles that were affected and other end-of-job items) and even came back to fully close off divert water around the struts for the solar panels (those go back on after the roof). We felt this was fabulous service. A chimney-repair person later commented on the good roof we have.

On September 16, 2021 Klam Construction Company workers/installers began a roofing job for me a day earlier to avoid potential rain forecast for late the following evening. The company added additional crew (6) to get the bulk of the difficult work done on the first day. This crew were incredible in the way they worked: quick, efficient, and happy. Some of them even sang as they worked! The next day 4 installers showed up at 7:00 AM and worked to finish the roof installation by noon. I had a beautiful new roof in a day and a half! Both days the crew cleaned up any debris and left my property spotless. I think this has got to be the best roofing company in Oregon. They provided superb roofing installation and excellent customer service to me. I highly recommend them for any roofing needs people have. Judging by the way they handled my job, I imagine they could do most anything!

Several homes in the 22 year old neighborhood I live in now have replaced roofs. I noticed one re-roofed home had a crisp finished look the others did not have. Klam Construction became my roofer of choice because of the superior install. Owens Corning agrees as Klam has their certification as a Platinum Installer. My thanks to the team, Job Well Done! A special thanks to Katie, the ops manager. A+

The team at KLAM Construction did excellent quality work on our roof! We had to have a complete tear off of our old roof, and start from scratch. They got the work done faster than we had expected, while taking care to protect our plants, and leaving our yard spotlessly clean. I would recommend KLAM highly to anyone looking to reroof their house!
