A ceiling stain does not show how far moisture has moved inside a roof. An infrared moisture survey screens a broad roof for thermal patterns that deserve closer investigation. In West Valley City, UT, it may help prioritize areas near the North SR-201 industrial corridor or distinguish sections near Fairbourne Station. Infrared is screening, not proof of wet insulation. We verify selected locations with test cuts or another agreed method before defining the affected area.
Survey quality depends on roof construction, surface conditions, timing, and repair history. We review the roof type, reported leaks, access, and known assembly changes. Then we identify areas where temperature patterns can be read alongside visible conditions. Findings are mapped and separated into confirmed, suspected, and inconclusive observations. That distinction helps the owner decide what needs opening, repair, monitoring, or no action.
