Build a Roof Age and Condition Estimator for Home Inspectors

1. 1

   Get ground truth from people who tear off roofs

   Partner with roofing contractors to label training data: photos of roofs whose actual install date is known (their own job records are gold), wear indicators by material (granule loss, curling, cracking for asphalt; different vocabularies for tile, metal, and wood). Models trained on verified-age roofs are the difference between a tool and a toy.

2. 2

   Fuse photos with paper evidence

   Permit records, prior listing photos, and property data often contain the actual reroof date; a lookup that finds '2016 reroof permit' turns an estimate into evidence, and disagreement between the records and the photos ('permit says 2016, wear suggests older; possible partial reroof') is precisely the insight inspectors get paid for surfacing.

3. 3

   Report ranges with visible reasoning

   Output is an estimated age range and remaining-life band with confidence level and the indicators found, formatted as an editable block for the inspector's report. Never a single number, never a warranty; the label 'estimate based on visual indicators and public records, subject to inspector judgment' is both honest and the liability posture the industry requires.

4. 4

   Keep the inspector as the author

   The tool assists a licensed or certified professional's report; it does not issue verdicts to consumers around them. That positioning respects inspection standards of practice, keeps errors-and-omissions carriers calm, and makes inspector associations a channel instead of an adversary.

5. 5

   Price per report with volume tiers

   Inspectors think in per-inspection economics; a few dollars per roof assessment inside a monthly plan matches how they buy report software and pays for itself the first time a documented roof-age call survives a realtor's pushback or an insurer's question.

6. 6

   Distribute through the report-software rails

   Inspection report platforms have marketplaces and integration programs; being the roof block inside the report inspectors already write beats a standalone app. Associations, inspection training schools, and drone-inspection communities complete the channel; the insurer-side aerial vendors are a different market and, honestly labeled, a validation of the technology rather than a competitor for this buyer.
