Commercial Roof Replacement
Commercial roof replacement is appropriate when moisture or deterioration is widespread, the deck or assembly is unsound, or repair and restoration cannot produce a dependable system. The specification must account for tear-off, insulation, drainage, rooftop equipment, code, access and business continuity.

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.
