A figure the company publishes about itself. It has not been independently audited, and no third-party estimate is used anywhere on this page.
- Notes on this entry
- Correction to a widely repeated name: "SELECT ShingleMaster" is LEGACY. CertainTeed’s current first-party credentials page uses company tiers MASTER / PRO / PREMIER plus Master Craftsman® individual credentials — https://www.certainteed.com/roofing-education-credential-us. Do not publish "SELECT ShingleMaster" as the current program name. HQ confirmed as Malvern, PA on their locations page; no street address is published there. gcpat.com sits behind a Cloudflare challenge and could not be read, so the Grace brand is recorded under CertainTeed rather than as a GCP record.
Where this came from
Details on this page were confirmed from the company’s own site on August 25, 2026. The page that was read. That is a record of what the company publishes about itself — not an endorsement, a rating or a check of its work.
This entry is editorial. CertainTeed did not pay to be listed, has no control over what it says, and appears here because it operates in this part of the roofing industry. Companies change their programs, their ownership and their product lines without announcing it, so treat the date above as the age of this information and confirm anything you are relying on at the source.

Hiring a roofer, rather than buying from one of these?
Manufacturers, distributors and B2B companies do not install roofs. The contractor directory is a separate part of this site, organised by state and then by city — start there, and check licence and insurance with the state board before work begins.
