Age is only one factor
Material type, installation quality, climate, ventilation, maintenance, and previous damage can all affect how a roof ages.
Look for system-wide issues
Widespread deterioration, recurring leaks, brittle or missing materials, failing flashing, and deck concerns can make replacement more appropriate than repeated localized work.
Plan the replacement scope
A written proposal should address tear-off, deck inspection, underlayment, flashing, ventilation, roofing material, cleanup, permits, and warranties.
