Updated September 29, 2026 by Chris Horton. Observation help, not a diagnosis or a remaining-life estimate. How we estimate costs
For homeowners looking at a roof that may need work and trying to decide whether the honest answer is a spot repair, a broader repair, or planning for replacement. Five steps. At the end you get the paths that fit what you observed, the observations still worth taking, and the questions to send a roofer. It does not tell you how many years your roof has left. Anyone who names a lifespan from photos or a description is guessing.
Answer from what you can see from the ground, from a ladder, or in the attic. Where you have not looked, choose Not observed: that becomes an observation worth taking, not a guess. The tool never promises a remaining lifespan. Roof lifespan depends on install quality, ventilation, climate and maintenance in ways that a description cannot capture.
Insurance and storm-damage claims follow their own rules and their own inspection process. If a claim is in progress or being considered, treat this tool as one input among several, not as the diagnosis your carrier will accept.
Step 1 of 5 · The roof, in general
The roof, in general
Baseline facts before observations.
What you observed
Tick every observation you can actually see. Leave the rest. Do not tick anything you have not observed.
How localized what you observed is
Repair scope depends more on where and how much than on any single symptom.
Context around the decision
Timing and climate change which paths make sense to investigate first.
Where you are, based on what you observed
Paths to investigate
Fits your observations means what you described points to this path. Worth investigating means it could fit but needs more looking. Unlikely to help means what you described points away. Needs a professional means a licensed roofer or inspector has to look before the path is decided.
Observations still worth taking
