Commercial roof coatings can help extend the life and improve the aesthetics of low-slope roofs. A roof coating acts as the first line of defense against UV damage and water infiltration, and reflective roof coatings can help reduce the temperature of the roof.

Every roof is different, and that's especially true when comparing commercial vs residential roofing, also known as low-slope vs steep-slope roofing.
