Commercial Roof Hail Damage
For building owners and property managers, commercial roof hail damage means more than just a roofing issue: it’s a financial risk. A hailstorm, even a short one, can compromise roofing systems by weakening membranes, damaging seams, and compromising waterproofing layers. The result is interrupted operations, increased maintenance costs, and user dissatisfaction.
Let’s discuss what hail damage does to common commercial roofing systems, so you can identify the damage sooner and call for help from reliable roofers, like Alliance Roofing.

Effects of Hail Damage on Commercial Roofs
The first thing to note is that hailstones vary in size, density, and velocity. Now, when large hail strikes a commercial roof, the roofing membrane absorbs the impact. Repeated storms over time puncture membranes, weaken seams, and expose insulation layers.
The damage is not always obvious from the ground, but in some cases it may result in visible cracks, dents, or even subtle fractures that allow water infiltration over the weeks or months that follow. Left untreated, this hidden damage can escalate into leaks, mold growth, and structural deterioration.

Hail Damage to TPO Roofs
Thermoplastic Polyolefin (TPO) roofing is a popular choice for commercial buildings because of its strength and energy-saving properties. If there’s a flat roof, it’s probably got TPO on it. But, commercial TPO roof systems are vulnerable to hail damage. Hailstones create punctures, tears, and compression-related damage in the membrane.
Typical evidence of hail damage on TPO roofs includes:

A prompt inspection after a storm is essential to prevent minor damage from escalating into major commercial property damage.
Hail Damage to Rolled Roofing

Rolled roofing systems, which are commonly installed on low-slope commercial buildings, are also susceptible to hail damage. The damage often presents as surface indentations, blistering, granule loss, or tears in the asphalt material.
Granule displacement is particularly problematic because it leaves the underlying bitumen exposed to ultraviolet radiation and moisture. Over time, the exposure accelerates aging and raises the likelihood of leaks.

FAQs
Are TPO roofs more resistant to hail damage compared to rolled roofing?
Generally, TPO roofs are more durable and energy-efficient than rolled roofing. However, they are not hail-proof either. They, too, can develop punctures, splits, and seam failures.
