How Hail Affects Your Commercial Roof

All weather is hard on your commercial roof, but it is a covering built to endure it. With regular maintenance, rain and shine will have minimal effect on your commercial rooftop. Yet, there is one common weather phenomenon in Texas that is especially hard on roofing – hail.

How Hail Affects a Commercial Roof

What hail does to a commercial roof ultimately depends on the type of roofing system that you have installed on your building.

Dents on Metal Roofing

If you have a metal commercial roof, the obvious concern is denting. Yet, there are many who believe if no one can really see the dents, they don’t matter much. Unfortunately, when a metal roof dents, it can often be followed with rust as its structural integrity has been compromised by the impact.

Cracking In Thermoplastics

In terms of sturdiness to hail, thermoplastic commercial roofing does well. With cover boards installed under the membrane, they can often withstand impact from hail stones as large as two inches. While they are sturdy, hail can still damage PVC, TPO, and EPDM roofing, especially if they have gotten quite old. You will notice cracking appears in impact areas that spreads in a circle pattern.

Displaced Granules on Bitumen or Built-Up Asphalt Roofing

The most enduring commercial roof type is roofing that still utilizes asphalt. This absorbs impact really well and in a two-ply construction, they can last for quite a while. However, frequent impact from hail stones can force it to shed the protective granules that help the roofing withstand other types of weather. This may mean areas need replacement.

If your commercial roof is looking a little worn, it is definitely time to make the replacement before things get even worse. Contact us today to see what Pillar Roofing & Construction can do to help get you a commercial roof that looks great and protect your business from all the elements.
