The lifespan of a commercial roof depends on the material and environmental conditions:

• EPDM Rubber Roofs: 20–30 years

• Metal Roofs: 40–60 years (very durable and low maintenance)

• Modified Bitumen & BUR: 15–25 years, depending on maintenance

Factors like weather exposure, roof slope, and quality of installation can impact longevity.

What are the signs my commercial roof needs repair or replacement?

Be proactive—look for these common red flags:

1. Leaks or water stains inside your building

If you notice any of these, schedule a professional roof inspection immediately to avoid more costly repairs later.

What is Commercial Roofing Verification?

Commercial Roofing Verification was created as an independent educational platform to help commercial property decision-makers evaluate roofing contractors.

The site does not rank, recommend, or endorse contractors.

It outlines publicly observable criteria related to licensing, permanence, and documentation.

HP Roofing Pro aligns with this framework and references it for educational purposes, but the verification platform operates independently.
