Commercial Roofing Market Overview

$15+ Billion Market with Consistent Demand

The U.S. commercial roofing market exceeds $15 billion annually, with steady demand driven by new construction, re-roofing cycles, and increasing focus on energy efficiency and sustainability. Commercial roofs have finite lifespans (15-30 years), creating predictable replacement cycles.
