Penetration & Flashing Audit in North Vancouver

Most roof leaks come from penetrations and flashings, not the field of the membrane. A targeted penetration and flashing audit reviews every drain, pipe, conduit, equipment curb, expansion joint and edge flashing condition, identifying deteriorating sealants, lifted edges, failed terminations and other common failure modes. We deliver these on commercial and institutional roofs as part of preventive maintenance programs or after a leak event.

What rain leak detection typically finds in North Vancouver

Flat-roof moisture in West Coast modern homes, parapet failures on Lonsdale commercial.

North Vancouver's built environment — 1950s–70s character homes, modernized acreages, growing Lower Lonsdale tower district, Seymour and Lynn Valley wood-frame stock — shapes how penetration & flashing audit is delivered locally. North Vancouver's heavy rainfall, mountain runoff, and steep terrain combine to make moisture and envelope work a constant. Many properties date from a leak-prone era of West Coast modern construction, with flat roofs, large overhangs, and complex drainage paths.
