Penetration & Flashing Audit in Delta

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 Delta

Flat-roof investigations on Tilbury and Annacis industrial roofs, ocean-exposed roofs in Tsawwassen and Boundary Bay.

Delta's built environment — single-family in Ladner and North Delta, low-rise development in Tsawwassen, agricultural and industrial in Tilbury and Ladner farmland — shapes how penetration & flashing audit is delivered locally. Most of Delta sits at or below sea level on the Fraser delta, protected by dykes and pump stations. Water-table issues, slab leaks and stormwater inflow into sanitary systems are recurring themes, and utility work has to respect strict drainage and ALR constraints.
