Best Commercial Roofing Contractors in Phoenix

Scott Roofing Company holds a distinction almost no Arizona roofing contractor can match: voted the #1 Roofing Contractor in Arizona by Arizona Business Magazine’s “Ranking Arizona” survey for 16 consecutive years, and named Arizona Roofing Contractor of the Year from 2008 through 2015. BBB accredited since 1983 — one of the longest continuous accreditation tenures among Phoenix roofers — and a 2022 BBB Torch Award for Ethics finalist, Scott Roofing has served over 40,000 Arizona residents since 1982. Their commercial portfolio is among the deepest in Phoenix, covering hospitals, warehouses, multi-family apartment complexes, churches, gymnasiums, and retirement communities in addition to residential projects.

In business since 1996, Canyon State Roofing and Consulting brings nearly 30 years of Phoenix market experience alongside two specialized certifications: Duro-Last single-ply membrane and Tile Roofing Institute (TRI) — making them one of the few Arizona firms certified in both flat commercial systems and precision tile installation. The company’s consulting arm sets them apart from purely installation-focused contractors, offering expert guidance to commercial property managers, HOAs, and owners navigating complex re-roofing or insurance decisions. Their commercial portfolio spans healthcare facilities, mining operations, multi-family buildings, hotels, offices, and retail centers across the Phoenix metro.

America Roofing LLC is one of the largest roofing contractors in the Phoenix metro, holding CR-42 licensing (the broadest Arizona classification covering both residential and commercial) and GAF certification in both the residential and commercial directories simultaneously — a distinction that reflects verified quality across market segments. In business since 1999, the company offers the widest material variety of any contractor on this list: asphalt and architectural shingles, concrete and clay tile, slate, metal roofing, BUR, modified bitumen, TPO single-ply, and spray foam. Their dual Phoenix and Tucson market presence underscores operational capacity that smaller firms cannot match.

Infinity Roofing & Siding holds a certification combination almost no Phoenix contractor achieves: GAF Master Elite (top 2% of all roofers nationwide), Owens Corning Platinum Preferred (highest OC tier), and CertainTeed Five Star Master Applicator (highest CT tier) — simultaneously. This tri-manufacturer certification unlocks the highest-tier extended warranties from all three major manufacturers and reflects sustained installation quality verified by three independent third parties. Ranked as a Top 50 Roofing Company in the U.S. and a HomeAdvisor Top Rated contractor, Infinity’s Phoenix operation serves both residential and commercial clients, with particular strength in storm damage restoration. Note: Infinity is a national firm with Arizona offices, rather than a locally founded Phoenix company.

TSM Roofing holds simultaneous GAF Master Elite and Owens Corning Platinum Preferred certifications — the top tier from each manufacturer — alongside a Tile Roofing Industry (TRI) Alliance certificate and ARCA membership. Named “Best of Phoenix 2024,” TSM serves both residential and commercial clients across the Phoenix metro and Prescott area. Their tile certification through TRI is particularly relevant in Phoenix, where concrete and clay tile are the dominant roofing system. The company also offers solar panel detachment and reset services, a growing need as Phoenix homeowners increasingly combine roofing projects with solar installations.

McMillan Brothers traces its roots to founder James McMillan Sr. in the 1940s and is now a 3rd generation family business serving the Chandler, Gilbert, and East Valley communities. With over 200 five-star reviews across Google, Yelp, Nextdoor, and other platforms and zero BBB complaints on file, McMillan Brothers has built a community reputation that large commercial contractors typically cannot match. They offer military, law enforcement, firefighter, teacher, and senior discounts as a reflection of their community-oriented values. Their combination of residential roofing and exterior painting makes them a practical one-stop-shop for exterior renovation projects.
