A coating decision begins with the roof beneath it.
Roof coating can be a maintenance and restoration option for some roof systems. The useful first question is whether the existing roof, substrate, drainage, details, and moisture conditions make it an appropriate candidate.
What should be checked before coating
- The existing membrane or roof surface
- Active leaks and signs of trapped moisture
- Seams, flashings, penetrations, walls, and edges
- Drainage and areas where water collects
- Cleaning, preparation, repair, and adhesion requirements
- Whether repair or replacement belongs in the scope instead
Preparation is part of the system
A coating plan should identify the roof-specific preparation and repairs required before application. The inspection is where the team can determine whether coating is a practical path for the property.
