Silicone coating on a small built-up roof is delaminating from the substrate because the top layer (embedded gravel/asphalt) is separating from the underlying BUR, and the owner is unsure whether to scrape and recoat with silicone or switch to a different coating system.

Workarounds Described

• Scraping off loose silicone by hand
• Using flashing cement and polyester fabric for repairs
• Considering aluminum fibered coating as a lower-cost alternative

Implied Software Gaps

• A diagnostic tool that analyzes substrate adhesion and recommends optimal recoating material
• A decision support system that compares long-term cost and performance of recoating options

RoofFix Advisor

A mobile app that guides roofing contractors and building owners through coating failure diagnosis by analyzing substrate condition photos and roof age/type. It recommends the optimal repair and recoating strategy (e.g., peel-and-stick membrane, silicone, acrylic, aluminum) with step-by-step instructions and material estimates, preventing costly trial-and-error.
