Inspect foam, coating and substrate together
Spray polyurethane foam roofing is installed as a continuous layer and protected by a coating. Its performance depends on sound adhesion, a maintained protective surface, workable drainage and durable details around walls, penetrations, drains and equipment.
Condition and diagnosis
A weathered coating does not automatically mean the foam has failed, and a bright new coating does not repair wet, damaged or unstable foam. Inspection should identify exposed or deteriorated areas, cracks, blisters, punctures, ponding, prior repairs and signs that moisture has entered the assembly.
Repair, restoration or replacement
Compatible local repairs and recoating can extend a serviceable system when preparation and dry conditions are adequate. Damaged areas must be removed or rebuilt as needed before the protective surface is renewed. Scope should state how thickness, reinforcement and detail transitions are handled.
What a complete proposal should define
Replacement becomes more relevant when moisture or adhesion problems are broad, drainage cannot be corrected within a restoration scope or prior repair layers prevent dependable integration. America Roofing compares those options before presenting one predetermined answer.
- Coating thickness and wear
- Foam adhesion and damage
- Moisture and drainage
- Walls, curbs and penetrations
