What is a common practice before applying reflective roof coatings?

Before applying reflective roof coatings, repairing any damaged areas is crucial to ensure that the surface is suitable for the application of the coating. Damaged areas, including cracks, blisters, and holes, can compromise the integrity of the roofing system. If these are not properly addressed beforehand, the reflective coating may not adhere appropriately, leading to premature failure, leaks, or other issues down the line.

By repairing damages prior to coating, you create a stable and healthy surface that can effectively reflect UV rays and perform well under various weather conditions. This practice also contributes to prolonging the lifespan of the entire roofing system, ensuring that the benefits of the reflective coating—such as energy efficiency and protection against the elements—are fully realized.

While power washing, applying a primer, and using protective tarps can all be part of the roofing process, they do not replace the fundamental need to ensure that the substrate is in good condition before applying a reflective roof coating.
