CASE STUDY
Merritt Civic Centre
Merritt, BC
The Merritt Civic Centre combines a flat roof section with an adjoining asphalt shingle roof over its approximately 5,750 sq ft footprint. Ahead of routine capital planning, the City of Merritt retained Pinpoint to confirm the roof’s true condition and rule out any hidden moisture before committing to a maintenance budget.
Pinpoint’s team scanned the entire accessible flat roof, combining daytime and nighttime aerial imaging with capacitance-based moisture scanning and selective core sampling — paying particular attention to drainage, penetrations, and the tie-in between the flat and shingle roof systems.

// Survey Scope & Methodology
A calibrated scan, confirmed by core sample
Pinpoint scanned the full flat roof using an RWS roof scanner and Tramex Dec Scanner calibrated to 20% at the start of inspection, cross-verified with a Moisture Encounter MEX5 handheld probe and a DJI Mavic 3 Enterprise day and night thermal drone pass. No readings anywhere on the roof exceeded the 20% dry threshold.
A core sample through the wood deck, fibreboard insulation, and 2-ply SBS membrane confirmed no visible moisture or saturation, and was resealed on site. The transition between the flat roof and the adjoining asphalt shingle roof was also inspected and found properly integrated with no visible deficiencies.
// What We Found
A fully dry roof, with only cosmetic wear to note
Every testing method agreed: capacitance scanning, handheld probes, and core sampling all confirmed 0% moisture across the entire flat roof, with no anomalies at drains, penetrations, or mechanical units. The adjoining asphalt shingle roof showed moderate weathering — shingle curling, granule loss, and some debris in the valleys — but these are cosmetic, age-related conditions rather than signs of active moisture intrusion.
Flat Roof Assembly
5,750 sq ft · 0% moisture, fully dry
Drains & Penetrations
No localized moisture accumulation
Shingle Roof Section
Weathering, curling & granule loss noted
Recommendation
No moisture-related remediation is required — the flat roof assembly is fully dry and performing as intended. Pinpoint recommended routine maintenance only: continued monitoring of the aging asphalt shingle section for further weathering, and clearing debris from valley areas to maintain proper drainage. No major capital expenditure is anticipated for 15+ years on the flat roof system.
