Anderson Roofing on Google
5 out of 5 stars

Anderson roofing is an all around great company to work with. From their office, management team, and field crews you won’t find a more professional, knowledgeable, and hard working roofing contractor in the area. I am a commercial superintendent and sub contractors are sometimes the hardest part of my job. This is not the case with Anderson I call they give a honest fair price and show up when they say they are going to. … Thank you Anderson roofing for sending me your A team.

I’ve been working with Anderson for 30 years. I call them with any roofing needs. My roof is flat (I know, crazy for Oregon) and they can address any issues. … They are responsive to calls and scheduling is seamless. The crew is efficient, hard-working and very professional. The last gold star goes to how tidy they are! I highly recommend them.

Working with this roofing team was a complete breath of fresh air. From day one, they treated me with absolute respect, kindness, and honest, peer-to-peer professionalism. … When the representative for our chosen product line suddenly went non-responsive, this roofing team didn’t make it my problem. They stepped up immediately, took complete ownership of that manufacturer relationship, and managed it flawlessly behind the scenes so I didn’t have to stress. …

We used Anderson roofing on major roof tear off and build back with a very high-profile client. While onsite they show nothing but professionalism. There work was clean and complete and the end of each day. They went out of their way to keep our customer happy and dry during the rainy season. I would highly recommend their team.

I was very pleased with the work Anderson Roofing did on our roof. The quality of the roof system they installed has been excellent, and it’s clear they take real pride in their craftsmanship. What stood out most was their responsiveness… On top of that, they went above and beyond throughout the project, handling small details we didn’t even think to ask about. Highly recommend Anderson Roofing to anyone in the area looking for a trustworthy, high-quality roofing contractor.
