Introduction: Cornerstone Roofing has been servicing all of Metrowest and its neighbors since 2008. Satisfied customers and word-of-mouth are our best advertisement and most of our work starts with a referral from a satisfied customer. We stay very informed about the latest in roofing technology and install everything with old school pride and craftsmanship. We are certified installers of GAF and Certainteed asphalt shingles; RPI and Firestone EPDM rubber. We have a large crew for big re-roofs and small specialized teams to tackle smaller repairs. If you have any other questions please call!! We've been roofing for over 30 years! If we didn't love it we'd be crazy by now!

Cornerstone is great. The owner Pete was very responsive and professional. He was efficient in his work and did a great job. He replumbed the kitchen sink and replaced leaky valves in the bathroom. I will definitely be using him again for other projects.

Roof Repair or Maintenance

Cornerstone Building Associates is fully insured. They came promptly after getting my call and was able to complete the repairs quickly right away. So the roof was ready to withstand the snow and rain that came a day later. Thank you!

    Once contact is made, we work to schedule the potential client for a initial inspection and evaluation of the roof. We then provide a accurate, detailed proposal.
