Roof coatings
A coating can protect and extend a roof only when the existing assembly is dry, stable and compatible. Our team assesses the roof, explains the practical options and prepares a scope that fits the building, access and timing.
Coatings are not a substitute for replacing saturated insulation, failed decking or a roof that cannot drain. The written scope should connect that decision to the roof's observed condition.
What a proper assessment looks for
The visible symptom is only the starting point. Materials above, below and beside the affected area need to be reviewed so the estimate reflects the actual water path and the condition of the substrate. The field review also checks adhesion and cleanliness of the existing surface.
- Adhesion and cleanliness of the existing surface.
- Wet insulation or trapped moisture.
- Cracks, open seams and failed flashings needing repair first.
- Drainage and ponding areas.
How the work moves from concern to closeout
Test the substrate
Identify the roof material, moisture condition and coating compatibility.
Repair and prepare
Clean thoroughly, reinforce seams and correct defects before coating.
Apply at specified coverage
Install primer and coating to the required thickness, then inspect cured film and details.
What should be clear before approval
A complete scope identifies the work area, preparation, materials, flashing treatment, cleanup and any exclusions. It should also explain how concealed damage will be documented and priced if it becomes visible after removal. Before approval, confirm how the contractor will assess cracks, open seams and failed flashings needing repair first.
Property protection and communication belong in the plan as well. Ask where materials will be staged, how landscaping or tenant areas will be protected and who will provide progress updates. Before approval, confirm how the contractor will assess cracks, open seams and failed flashings needing repair first.
Why the surrounding roof matters
Coatings are not a substitute for replacing saturated insulation, failed decking or a roof that cannot drain.
The inspection should also account for access, weather exposure, existing warranties and any related gutter, ventilation or wall details. That broader view prevents a narrow fix from moving water to the next weak point. The field review also checks adhesion and cleanliness of the existing surface.

Questions customers ask
How is the scope for roof coatings determined?
A coating can protect and extend a roof only when the existing assembly is dry, stable and compatible. The field review checks adhesion and cleanliness of the existing surface, wet insulation or trapped moisture and cracks, open seams and failed flashings needing repair first. For roof coatings, each line item should connect to adhesion and cleanliness of the existing surface.
When is a different or larger roofing scope more practical?
Coatings are not a substitute for replacing saturated insulation, failed decking or a roof that cannot drain. The recommendation should compare expected service life, repeat-failure risk and the cost of each option. For roof coatings, each line item should connect to adhesion and cleanliness of the existing surface.
What should be shared before the inspection?
Provide the property address, roof type if known, where the problem appears, when it started and any safe photos. Mention access restrictions, active interior water and deadlines that affect scheduling. Also note any symptom or access issue related to cracks, open seams and failed flashings needing repair first.
Discuss roof coatings with a clear starting point
Share the property address, roof type, observed issue and preferred timing. The response can focus on restoring a suitable roof surface rather than hiding failure and the inspection details needed before a scope is prepared.
