Commercial Roofing

Commercial roofing is a different game from residential. The materials, methods, and expertise required are specialized. A leaking commercial roof means business interruption, inventory damage, and liability risk.

Average Cost: $4 - $10/sq ft depending on system

Commercial Roofing Systems

TPO (thermoplastic polyolefin) is the most popular for flat commercial roofs, offering durability at $4-8/sq ft. EPDM rubber roofing ($3-7/sq ft) is proven and affordable. PVC membrane ($5-10/sq ft) offers superior chemical resistance. Built-up roofing (BUR) and modified bitumen ($4-8/sq ft) remain reliable options for larger buildings.

What to Look For

Commercial roofing contractors should carry higher insurance limits ($1M+ general liability), have experience with your specific roof type, provide maintenance plans, and offer warranty options. Ask for references from similar-sized projects.

Maintenance Matters

Commercial roofs need annual inspections and maintenance to reach full lifespan. A good contractor will offer a maintenance agreement that includes semi-annual inspections, drain cleaning, and minor repairs. This prevents small issues from becoming emergency replacements.
