    I had a great experience with Keystone Builders. They replaced my roof (due to storm damage) and Juan (project manager) and his crew did an excellent job. Juan thoroughly explained the process. They completed the job ahead of schedule and … More I was impressed with the great job on cleanup. And shout out to Denny (who helped with insurance approval) for being on-site to ensure all went smoothly. I highly recommend Keystone!

    Keystone replaced our roof and gutters. They were amazing! We worked with Preston and Juan’s team. Preston explained everything clearly to us during the initial meeting. He helped us with our insurance company claim and was there for the … More insurance company inspection to answer any questions. Juan’s team was very efficient with the installation and cleanup process was great. Nothing was left behind. Would highly recommend this company. Especially Preston!!

    Last year a hail storm came through and created damages to our roof. In May 2025 we started working with Keystone Builders (specifically with Tyler, Juan, and Carlo's Team) on how to file a claim, and set up a date to get our roof … More replaced. From the time of the inspection to getting the roof done, we received great communication, professionalism, and work from Keystone Builders. The team arrived as expected and got straight to work with no delay. We definitely recommend Keystone Builders to anyone looking to get their roof replaced!
