St. Augustine School is a 12,155 sq ft educational facility with a 10-year-old modified bitumen roof spanning four sections. With no reported leaks but visible age-related wear, the school retained Pinpoint to confirm exactly how much of the roof had trapped moisture.
Pinpoint scanned all four roof sections (RA-1 through RA-4) using an RWS roof scanner and Tramex Dec Scanner, cross-checked with a DJI Mavic 3 Enterprise nighttime thermal drone pass. Elevated readings were hand-verified with a moisture meter and confirmed with targeted core cuts — including one location where water poured directly out of the sample.
RA-1 and RA-4 scanned completely dry. RA-2 showed 15.8% of its area wet, concentrated between the roofing plies near an HVAC unit, with the insulation beneath confirmed dry by core cut. RA-3 showed 4.4% wet, including one saturated core sample near a roof penetration and drain — a likely leak source flagged for immediate attention. Across both wet zones, the underlying insulation remained intact and dry.
A full roof replacement was not necessary. With moisture isolated to limited areas and insulation intact and dry across the majority of the roof, Pinpoint recommended a targeted repair approach: address the wet sections in RA-2 and RA-3 — including the penetration near the drain in RA-3 — to prevent further intrusion.
