FAQs

The majority of commercial flat roofs utilize single-ply membrane systems such as TPO roofing (thermoplastic polyolefin) and EPDM (rubber), or multi-layer systems including built-up roofing (BUR) and modified bitumen.

Pricing differs significantly based on material type and roof size. You can generally expect approximately $8 to $15 per square foot for EPDM and $8 to $15 for TPO.

The lifespan varies depending on the roofing material and quality of maintenance. Single-ply systems such as TPO and EPDM typically last between 15 to 30 years.

While aerial imagery can provide preliminary estimates, an on-site inspection is essential to avoid expensive miscalculations regarding deck deterioration, insulation requirements, and drainage conditions.

The leading causes include punctures resulting from foot traffic, deteriorating flashings around roof penetrations, and standing water caused by inadequate drainage.

Professionals in the industry suggest inspecting commercial roofs no less than twice annually—preferably during spring and fall—and following any significant weather events.
