Repair or replace my roof?
Turn the signs you already know into a clearer conversation with a roofer. This tool does not inspect your roof or make a safety determination.
Evidence behind the signals
NRCA notes that a leak does not automatically require full replacement; localized flashing or roof-section damage can also cause leaks. It also highlights visible warning signs such as cracked, warped or missing shingles, deteriorated flashing and indoor moisture indicators.
Owens Corning identifies aging, storm damage and leaking/water damage as major replacement-discussion triggers, with curling, cracking and granule loss among common aging signals.

Frequently asked questions
Does one leak mean I need a new roof?
No. A localized leak can come from flashing or a damaged section. The extent, roof condition and repair history matter.
Does roof age alone decide replacement?
No. Age is one signal. Condition, damage extent, leaks and repair history should be considered together.
What if I see sagging?
Treat known sagging or structural concern as a reason for professional inspection rather than relying on this tool's directional result.
