The flat rooftops that are on commercial structures such as stores, medical facilities and factories require roof coating to protect the surfaces. While angled roofs will help moisture run off of a building, rainwater or snowmelt tends to puddle on flat rooftops, leading to water leaks into the building, causing damage to the drywall and electrical wiring.

Fortunately, roofing technicians can apply liquid roof coating materials in only a few hours by using ready-made substances along with specialized tools for spreading the liquid. Roof coating materials are formulated to stretch or expand slightly in hot or cold weather conditions, but this elasticity is also important as the other roofing materials degrade.

Roof coating is designed for being the top layer on a rooftop, but in some cases, there are additional waterproof layers underneath this substance. The roof coating materials are primarily formulated for repelling the moisture from ice, snow or rain, and there is no concern about its beauty or the durability from anyone walking on it.

The goal of roof coating is to create a 100 percent seamless surface so that no moisture enters the rooftop of a building to damage the underlying materials, extending the life span of a roof. A professional roofer will check the building’s rooftop for depressions in order to create thicker areas of roof coating to prevent puddles that can lead to moisture damage.
