As a business owner, your building's roof is easy to overlook—until a leak, draft, or costly damage brings it front and center. So, how often should you replace a commercial roof? The answer depends on a few key factors, but knowing the basics can save you thousands in the long run.

At Precision Roofing Services in Fuquay-Varina, NC, we believe in prolonging the life of your existing roof before suggesting a full replacement. Here’s what you need to know:

1. Know Your Roof Type and Lifespan

Different commercial roofing materials have different lifespans. Here's a general guide:

EPDM (rubber roofing): 20–30 years
TPO/PVC roofing: 15–25 years
Modified Bitumen: 20+ years
Metal roofing: 30–45 years
Built-Up Roofing (BUR): 20–30 years

👉 Pro Tip: Regular maintenance can extend these lifespans significantly!

2. Watch for Warning Signs

You don’t have to wait until the ceiling drips to take action. Call a professional if you notice:

Pooling water on a flat roof
Increased energy bills
Bubbling or blistering membranes
Mold, mildew, or interior water stains
Flashing damage around vents or edges

3. Weather + Wear & Tear = Shorter Lifespan

In North Carolina, commercial roofs face harsh sun, spring storms, hail, and even hurricanes. Over time, these elements can cause major wear. Even if your roof is under 20 years old, regular inspections are critical.

4. How Often Should You Replace It, Really?

If you’re seeing major deterioration, ongoing leaks, or high repair costs year after year, replacement may be more cost-effective. Most commercial roofs should be inspected annually and replaced around the 20–30 year mark—depending on type and maintenance.

5. Prolong, Don’t Replace (Unless You Have To)

At Precision Roofing Services, we’re not here to sell you a new roof unless you truly need one. Our goal is to extend the life of your current roof with honest inspections, regular maintenance, and expert repairs.
