Answer in brief
Can you coat a leaking roof?
A leaking roof should not simply be coated. Active defects, wet insulation, failed decking and incompatible materials must be identified and corrected before an eligible roof receives a specified coating system.
Decision inputs
What changes the answer.
Leak source
This factor should be verified for the actual commercial roof rather than assumed from a photograph, age or square-foot estimate alone.
Trapped moisture
This factor should be verified for the actual commercial roof rather than assumed from a photograph, age or square-foot estimate alone.
Substrate integrity
This factor should be verified for the actual commercial roof rather than assumed from a photograph, age or square-foot estimate alone.
Compatibility and adhesion
This factor should be verified for the actual commercial roof rather than assumed from a photograph, age or square-foot estimate alone.
Required detail repairs

Require moisture evaluation and repair documentation before coating begins.

Commercial Silicone Roof Restoration
A silicone roof coating can restore certain weathered low-slope roofs, but it is not a substitute for replacing wet insulation, failed decking or an unsound membrane. Eligibility should be determined through inspection, moisture evaluation, repairs and adhesion testing.

What information should a roofing estimate include?
The estimate should define measured quantities, system and product, removal, deck assumptions, flashings, ventilation or insulation work, cleanup, warranty and how hidden conditions are handled.
Can a roof be diagnosed from photos alone?
Photos can support triage and documentation, but they may not reveal deck condition, trapped moisture, attachment, ventilation or every flashing detail. Building-specific advice normally requires an appropriate inspection.
