Homeowner had a roof valley installed with shingles rather than specified metal W-channel, and the contractor has not inspected the questionable workmanship that previously leaked.

Existing solutions rely on the contractor's willingness to inspect and redo work, but there's no independent, systematic way to evaluate roof valley installation compliance with specifications and flag potential leak risks.

Automated compliance checking of roofing installation against contract specifications

App Concept

RoofSpec Pro

An app that allows homeowners to document roof installations with photos, automatically compare against contract specifications (e.g., metal vs. shingle valleys), and generate a compliance report. The app provides a checklist of critical details (valley type, overlap, flashing count) so the homeowner can hold the contractor accountable with objective evidence.

Key Features

Photo-based installation check with specification matching
Automatic detection of specified vs. actual materials (e.g., metal valley vs shingle)
Contract specification import and rule-based validation
Guided inspection workflow for critical leak-prone areas like valleys, flashing, and penetrations

Target Users: Homeowners who are having new roof installations or tear-offs, especially those with detailed contracts and past leak issues, working with residential roofing contractors.

Revenue Model: $9.99 per inspection report (one-time fee) or $19.99 for unlimited reports during a 3-month project window.
