Our house was in need of a new roof and we got many estimates from roofing companies. Our roof was a torch down that had cracked and allowed for some water damage to eaves and insulation. Hector came out and did a thorough inspection of our roof, listened to our concerns/questions as our roof style was pretty unique and we had a variety of different options from previous roofers. Cornerstone's bid came in at a price we could afford and included fixing areas of damage and rebuilding it the right way. Hector and Sarai communicated with us throughout the entire project and we had a great overall experience. We've had the new roof for about 2 years now and couldn't be happier with the end product. Would absolutely recommend Cornerstone!

After a large truck backed into our building I reached out to a few companies to replace our damaged gutters. Cornerstone not only had the most competitive prices, they were also the only ones able to make a close match to our custom painted metal roof and the original gutter style. They exceeded expectations by coming out right after our initial quote late on a Friday when we had a leak due to an unrelated issue. They kindly helped troubleshoot the problem (making a run to get supplies for a temporary fix) while connecting us with a plumber who could create a long term solution. We had a couple questions after our install and they took the time to meet us on a weekend to go over everything ensuring we were happy with the final product. We will absolutely use Hector and Sarai in the future, they go above and beyond.

What can I say about this amazing company? I recently discovered an issue with my bathroom vent—there was no proper exhaust installed, and the air was going directly into the roof! I reached out to Cornerstone Metal Roofing, knowing the fix would require removing and replacing part of my metal roof to install a proper exhaust pipe.

Cornerstone came out right away. Not only did they install the exhaust pipe correctly, but they also repaired and replaced the affected section of my roof with such professionalism and care. This is actually my second time using Cornerstone, and both experiences have been nothing short of excellent.

Hector, who owns the company with his wife, is a true professional and such a pleasure to work with. Their communication is clear, their work is top-notch, and I genuinely don’t see myself ever using another roofing company. I highly recommend Cornerstone Metal Roofing—worth every penny!

These young men were working on our neighbors roof. I contacted them, asked for a business card, which he gave me.
I emailed the company, and they responded right away. Usually, we have to wait for a response, if it ever happens..
Cornerstone Metal Roofing is a first rate company.
We would highly recommend them.Fast, efficient,friendly, fair...awesome people to work with.

I recently had a standing seam metal roof installed on my garage and am very happy with the service, quality, and price. I also had Cornerstone replace some facia board and install gutters, all very reasonably priced and great quality. I'd definitely give Hector and his team a call for future roofing needs.

We discovered a leak in the roof of old church building and contacted Cornerstone Metal Roofing because they had installed a metal roof on our new church building. Hector came out that same day and installed a tarp over the leaking roof. We had to delay repairs for 2 months while the Insurance adjuster reviewed the claim, visited the site and gave us a settlement check. While this was going on a windstorm blew off part of the tarp and Hector again came out and re-installed the tarp. Upon receiving approval from the church board, we contacted Hector and he came with his team and removed the old roofing and installed the new roofing. The old roofing had so much mold and mildew that we had 46 sheets of new plywood installed during the roofing process. We appreciate Cornerstone Metal Roofing going over and above helping stop additional damage by being so prompt installing the tarp on the roof. And by being patient while we received approval to scheduling the installation of the new roof.

I could not be more pleased with the work that Hector did installing our new metal roof. He was kind, punctual, and the quality of the completed project exceeded expectations.

I appreciated their willingness to take on a small job when others refused. Our 8x14 shed needed a new roof. Hector showed up on time for the initial consultation. A reasonable bid was provided in less than 24 hours. The day the work was to be completed Hector was on time and communicated with me throughout the process. The 2 plastic skylights were damaged, but he had a solution that would not add to the cost of the work. The area around the shed was clean and all debris was removed as promised. Honestly, I would hire this company again without hesitation. They exceeded my expectations because they were on time, professional, thoughtful, and delivered exactly what was promised at an affordable price. Thank you!

Let me talk about my journey trying to get my roof done, a year ago me and my wife were walking in the neighborhood and saw contractors doing someone’s roof and I went ahead and talked to that person to give me a quote on mine, he wanted to do it under the table and came back to me with a quote it was way beyond our budget without warranty, so I tried looking around, so I typed in my number on some app and hector from cornerstone metal roofing was the first person that called me up not knowing that there was a barrage of roofing companies that will call me up too. I went ahead and gave them all a chance to a sales pitch for them to win my business. I saw through every single one of them and Hector and his wife was the only one that was within our budget and had the assurance of delivering. They came the next day easy to talk to and straight to the point. And was I amazed, It was hassle free like they weren’t even there, they did an excellent job and the work was done on time, they even did a great job with the cleanup. They even did extra work, getting rid of our satellite, putting additional roof reinforcements and painting our vents to match the color of the roof. All in all I’m beyond satisfied, in fact I will recommend Cornerstone Metal Roofing to anyone I know. BEST IN THE BUSINESS. And thank you very much for making it as smooth as possible and keeping our mind at ease.

Hector Alvarado, the owner, was on time, on budget, and performed a superb job.
The work was done on our new church building, St
George Episcopal church in Maple Valley. About 6000 Square of metal roofing.

Cornerstone did a fantastic job on my roof replacement at a reasonable price. Hector's suggestion on a new (to me) type of roofing was a great call for our low slope roof. The attention to detail, additional steps taken to ensure a long lifespan, and willingness to communicate with me every step of the way went beyond what I was expecting. This is a small business you can trust, and it's not bologna when they say they care.

I decided against traditional shingles for the roof and chose to go with metal. I could not be happier about that decision to this day. Hector at Cornerstone Metal Roofing ensured every step of the project was done with True Craftsmanship. There won't be many better people than Hector to have work on my home and yours. Very pleased... we had a storm this year that blew near 80-100 lbs limbs onto our roof, with no damage!!! Again I could not be happier.

When choosing a roofing company, consider their experience, customer reviews, warranty offerings, and quality of materials.

Warning signs that your roofing contractor might be ripping you off include vague contracts, pressure to pay large upfront deposits, lack of proper documentation, and unexplained price increases. Always ask for itemized estimates and written guarantees, and avoid contractors who avoid answering your questions directly.
