What is a commercial roof moisture survey?

A roof moisture survey uses an appropriate test method to help identify suspected wet areas beneath the surface. Findings are typically confirmed with test cuts and used to plan repairs, restoration or replacement.

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.
