Hail Damage on TPO Roofs: What Alabama Property Owners Need to Know

This baseball-sized hailstone hit a commercial TPO roof during a recent Alabama storm — damage like this often isn’t visible from the ground.

When a hailstorm rolls through Alabama, one of the first things you should check is your roof. For property owners with a TPO roof (Thermoplastic Olefin), hail can pose a serious threat—not always visible at first glance. At Birmingham Roofs, we specialize in both installing and repairing TPO roofing systems, and we know exactly what to look for after a storm hits.

Whether you're managing a commercial building in Birmingham or overseeing maintenance at a church in Bessemer, this guide will walk you through everything you need to know about hail damage on TPO roofs.

What Is TPO Roofing?

TPO roofing is a single-ply white membrane that’s heat-welded together and laid over insulation. It’s a popular choice for flat and low-slope commercial roofs because of its energy efficiency, durability, and affordability.

But while TPO holds up well in the Alabama heat, hail is a different story.

Can Hail Damage a TPO Roof?

Yes. Hail can cause significant damage to a TPO membrane—even if you can’t see it right away. Larger hailstones, especially those over 1" in diameter, can create:

• Punctures or tears in the membrane

• Delamination from the substrate

• Bruising and soft spots in the insulation beneath

• Compromised seams or flashing around penetrations like AC units or skylights

Over time, even small hail impacts can cause leaks, ponding water, and insulation failure.

“Visible hail strike on a TPO membrane — these impact points can lead to hidden leaks and insulation damage if left unaddressed.”

Signs of Hail Damage on TPO Roofs

It’s not always obvious. After a storm, you may not see big holes or rips—but that doesn’t mean you're in the clear. Here are signs to look for:

• Circular indentations or “blisters” in the membrane

• Hairline cracks or surface fractures

• Dirt rings around impact spots (where water has pooled and evaporated)

• Damage to rooftop equipment, which can suggest hail impact elsewhere

• Wet insulation detected through infrared scans or core cuts

Tip: Always get a professional roof inspection after a major storm, especially if your property has a flat TPO roof.

Filing an insurance claim after hail damage is often the first step toward getting your TPO roof repaired or replaced.

What To Do If You Suspect Hail Damage

1. Document the damage. Take photos and note the date of the storm.

2. Call Birmingham Roofs. We’ll provide a free inspection and help determine the extent of the damage.

3. Check your insurance policy. Most commercial property policies cover hail damage—but claims must be filed within a limited time.

4. Avoid patch jobs. Temporary fixes can lead to bigger problems. Let us assess whether a section replacement or full re-cover is best.

TPO Roof Replacement vs. Repair After Hail

Depending on the extent of the damage and the age of your roof, your options may include:

• Spot Repair – For minor punctures or isolated areas

• Recovering with New TPO – If the insulation is dry and in good shape

• Full Tear-Off and Replacement – Often required when insulation is saturated or the membrane is extensively compromised

At Birmingham Roofs, we’ve replaced hail-damaged TPO roofs all across Alabama—including in Birmingham, Tuscaloosa, Bessemer, and beyond. We work directly with your insurance adjuster to make the process smooth and stress-free.
