Compared to residential roofing systems, a commercial roof can be a bit more difficult to care for as they are larger than residential roofs and even lack a slope. This means that it’s more prone to damage compared to its residential counterpart.

In fact, according to professionals, one way you can do this is by adding coatings to the roof.
