Cornerstone Roofing, Siding & Gutters

I appreciated that Cornerstone communicated with me every step of the way and that I could ask the project manager specific questions about what was being installed on my roof. Services: Roof installation, Skylight installation, Gutter installation, Attic venting

"Cornerstone was spot on from beginning to end. Starting with the estimator to the job clean up. They were very thorough & professional. I requested a specific time frame and they were more than accommodating. The first day went like clockwork with the crew showing up right on the quoted time and the dumpster showing up within 5 minutes of the crew.

Tear off was done in a day, shingles were delivered and stacked on the roof that same evening and the job was completed the next day. Two skylights were also replaced and are beautiful. I watched several houses in our neighborhood take at least 3-4 days. The project was completed with a roof inspection a couple of days later and I couldn't be happier. I got estimates from six companies and Cornerstone was who I felt most comfortable with. The whole experience was excellent and I would recommend them to anyone."

Every question or concern we had was addressed. Very friendly and professional workers, project coordinator and quote estimator. Quick, thorough and the roof looks fantastic! Services: Roof installation, Skylight installation, Gutter installation

CSR installed a new roof on our home in June 2021. Their customer service and sales people were outstanding, and the roof itself is great, though we're still "proving" it now that we're in winter. The foreman for the job also very kindly refinished a porch-ceiling board that we thought was rotten but just needed some surface fixes. We really appreciated that.

We ran into some issues with the installation crew (disposal of old roof materials and unused supplies, broke a flower pot and damaged our rose bush, etc.), but the company quickly addressed this issue with me when I had posted about it (and to be fair, I neglected to bring it up with them privately at the time). They issued us a gift card to compensate for the damage, and said they would address the issues with their install crew. I appreciate their prompt response, and am satisfied with their promise to prevent such issues in the future. Thank you.

We would highly recommend Cornerstone Roofing, Inc. (Bothell, Wa.). The whole staff was professional, knowledgeable and a pleasure to work with. The estimate from Dave Lundeen was very competitive. He did not try to sell us unnecessary product and thoroughly discussed the options. He provided us with detailed photographs and drawings of the work to be done.

We had a number of bids and Dave was the only one who took the time to look in the attic crawl space and discussed the interior condition. It was a pleasure to work with Kristy Hoff (Coordinator)who's professionalism and response with communication was excellent. The whole office staff went out of their way to be helpful. The remainder of the team Greg (the project manager) who was outstanding in responding to questions and keeping us informed, to the roofing crew who were very fast and efficient as well as respectful of the surrounding foliage, to Alberto who did the final inspection and answered all our questions. All were excellent in their service.

I strongly recommend Cornerstone Roofing. Michael, who quoted my roof replacement, was a pleasure to work with. He was honest, professional and knowledgeable. The crew that came out to do the install was fast, efficient, and clean. The whole experience was exceptional. Service: Roof installation

CSR went above my expectations on my roof installation. Very professional starting with initial bid, billed exactly as quoted, quality install and great clean up daily, they even send out a QC after roof is complete to go over the roof installation. Overall a topnotch company I would highly recommend!

You could not ask for a more honest, amazing, responsible, and respectable roofing company. From the owner, Jim, who is a delight, to the office, who are super nice and helpful, to Craig, the awesome (and funny) foreman who seems to work 24/7, to the roofers themselves, who are pleasant and the hardest working roofers I've ever seen. Even my handyman, who has been over here while they're working, commented on how crazy hard they work.

But in addition to the obvious quality, their finesse and skill with fixing my sagging roofline, the ease with which they removed a surprise double-done roof with two layers, and rotting wood, the true pleasure it is to work with such a competent and friendly and nice team cannot be beat. Even the gazebo shows the precision craftsmanship! I highly, HIGHLY, recommend!

Cornerstone Roofing did the roof replacement of our home in August 2020 and I highly recommend them. We had the pleasure of meeting James at the beginning and during our roof replacement proposal process; he is professional, cordial and very easy to communicate with and will answer all your questions honestly and up front. The office staff is equally as great - I visited their office and had very friendly and professional interactions with the staff including Sara.

Our project was carried out like clockwork and my interactions with all involved were Five-Star. Thank you Kristy for your email communications leading up to, during and after the project; Thank you Craig and Oswaldo's team who performed the roof work and to Juan Carlos who completed our inspection and Alberto who came by for final clean-up - it was so easy to be able to contact and communicate with all of them either while onsite during the project or by calling/messaging with Craig - they responded to all my questions and concerns and I would say in our case went "above and beyond." We are very happy with the completed project, workmanship and our new replacement roof and are truly grateful to all of the Cornerstone Roofing team.

They recently replaced our entire roof. Very professional from the estimating process to the actual work. I got several competitive bids and they were priced similarly, but Cornerstone offered a much more comprehensive warranty. There was an accident during the replacement that led to some small drywall damage in one of our ceilings. We sent a picture to the project manager and that was all we had to do.

Within an hour I was copied on an email to a drywall repair person saying that it needed repair right away and Cornerstone should be billed. It was patched competently in two days. No waiting, no hassle. Mistakes happen, the important thing is how they are addressed. I was very impressed.

Awesome work...On time, polite, professional... I could go on and on.... oh and the prices, UNBEATABLE!

These guys did a great job on a restore project for a storage building I had in my back yard. Redid the roofing and siding after a terrible storm came through. Dependable and reliable, while also reasonable and friendly. Will absolutely be my go-to for all projects in the future!!

Cornerstone does quality work in a timely and proffesional manner. I was very pleased with my roof and highly recommend them for any job!

Even though they were busy they were able to get me in and do a very professional job from start to finish. Highly recommend

Cornerstone did exactly what I expected and more! (And nowadays, that is rare!) I even watched as they used a metal detector to go around my house to be sure all the nails were picked up. Sometimes, its the little details that make you know they care about what they do! Highly recommend Cornerstone!

Did a great job replacing my gutters. They left no mess. Would recommend them. Great price as well.
