The Cranbrook Fire Hall is a 5,200 sq ft emergency services facility housing active apparatus bays and rooftop mechanical equipment. Ahead of routine capital planning, the City of Cranbrook retained Pinpoint to complete a full roof moisture and thermal survey.
Pinpoint scanned the entire accessible roof using an RWS roof scanner and Tramex Dec Scanner, cross-verified with a Moisture Encounter MEX5 handheld probe and a DJI Mavic 3 Enterprise nighttime thermal drone pass. Selective core sampling confirmed conditions at key locations, including one dry cut over the truck bay and one confirmed-wet cut near the drain and HVAC unit.
Roughly 150 sq ft of wet insulation was identified — about 2.9% of the total roof area — concentrated between the roof drain and adjacent HVAC unit. Thermal imaging and capacitance scanning agreed: outside this one zone, surface temperatures and moisture readings were consistent and dry across the field membrane, metal roof sections, and perimeter. No ponding, distress, or active water entry was observed on the standing-seam metal roof.
No full roof replacement is warranted — the system is largely performing as intended. Pinpoint recommended a targeted repair at the drain/HVAC zone to remove and replace the wet insulation before it spreads, along with continued routine inspection of that area given its proximity to mechanical equipment and drainage.
