4 Biggest Threats To A Commercial Roof

4 Biggest Threats To A Commercial Roof

Everything and everyone has a weakness, vulnerability, or risk to something. For people, that currently means fight the COVID-19 virus risk that has ravaged the world in general and the USA in particular. But for other things, such as cars, there are other threats, like bored teenagers, or other malicious people scratching paint jobs with keys.

The same is true even with much more substantial items, such as the roof of a commercial building. Nothing lasts forever, and every roof, whether commercial or residential, has a fixed lifespan. But some things can pose a higher risk to a roof, leading to repairs or even replacing a roof entirely if an issue isn’t caught in time. Here are four of the most significant threats a commercial roof faces.

Hail Damage

This is an event that can’t be predicted, but, over a long enough timeline, a hail storm is inevitable. Because hail is literally “pebbles and rocks falling from the sky,” the size and velocity of hail can be damaging to a roof. It doesn’t always occur, but when weather conditions, for example, create hail the size of a golf ball, that can build up enough speed that it will make a dent or other damage in a roof when it hits.

Wind Damage

Another extreme weather event that can happen annually, especially with tornado seasons, is strong winds. While a brand new roof is unlikely to be affected by high-speed winds, as time passes, without proper inspection and maintenance, this can change. Strong winds can eventually tear off entire chunks of a roof, leaving the structures underneath exposed and vulnerable to even more significant damage.


This is a significant threat for residential roofs, but even a commercial roof that uses asphalt may be under threat as well. Moss or algae growing on a roof can weaken the structural integrity of that roof. Moss, if it gets under shingles, for example, can loosen the adherence the shingle has to its surface as the moss grows. Algae can dry out the granules in asphalt as it absorbs all nearby available moisture, weakening the protective qualities of that portion of the roof.


This is probably the single biggest threat to a commercial roof. In most instances, due to the size of a commercial building, the roof is a flat surface, not built at a slope the way smaller residential buildings are. As a result of this, water from rainfall doesn’t naturally flow off the roof due to the work of gravity on an incline.

With proper drainage and regular maintenance to ensure parts of a roof don’t sag, ponding can be avoided. However, if these precautions aren’t taken, water can sit on a roof, sometimes for days, without you knowing about it unless you conduct your own inspections after storms. If this happens, that water can penetrate the roof and eventually damage it and other parts of your building.
