Manufacturer Warranties

As a certified installer for both CertainTeed and GAF, we're able to offer manufacturer-backed warranties that go beyond standard coverage. Our CertainTeed ShingleMaster PRO status, held since 2017, reflects a track record of quality installations recognized directly by the manufacturer. Depending on the CertainTeed system installed on your home, this certification can qualify you for extended material and workmanship coverage — we'll walk you through which options apply once we've scoped your project.

We also hold GAF Certified Plus certification, which allows us to offer the System Plus Limited Warranty and the Silver Pledge Limited Warranty on qualifying GAF roof systems. Coverage, terms, and eligibility vary depending on the products installed, so we'll confirm exactly what your roof qualifies for as part of your estimate.

Our Workmanship Warranty

Licensed and Insured

Mike Killeen Quality Roofing Co. has been serving [service area] since 1987. Because California requires a new contractor's license number whenever a business's legal structure changes, our license number has been reissued a few times over the years as the company evolved — most recently in December 2025. Each time, the underlying business, our team, and our commitment to quality have stayed the same; only the paperwork has changed. Our current license is #1147273 (Classification C39 – Roofing), active and in good standing with the CSLB through December 31, 2027. You can verify this directly on the CSLB license lookup at any time.

The company also carries a $25,000 contractor's bond through Travelers Casualty and Surety Company of America, and workers' compensation coverage through Continental Indemnity Company.
