Roof. Wall. Waterproofing. One contractor.

Building envelope coordination, custom sheet metal fabrication and preventative maintenance programs delivered by the same commercial crews trusted on our roofing and waterproofing projects.

01 · Envelope Coordination

Building envelope coordination.

Roof, wall and waterproofing scopes coordinated by a single accountable contractor — eliminating the tie-in gaps where multi-trade envelopes typically fail. We support consultants on envelope rehabilitation, roof-to-wall interface detailing and capital planning programs.

02 · Sheet Metal & Flashing

Custom-fabricated sheet metal.

Our in-house sheet metal shop fabricates flashings, parapet caps and architectural details to consultant tolerances — from standing-seam wall panels to custom parapet caps in prefinished steel, aluminum, copper and zinc. In-house fabrication means tighter quality control and shorter lead times.

03 · Service & Maintenance

Maintenance programs that prevent emergencies.

Annual inspection programs and preventative maintenance contracts for owners, property managers and strata councils. Every site visit is documented and fed back into lifecycle and capital planning.

Why Owners Choose Supreme

Why owners choose Supreme for envelope work.

Single Point of Accountability

In-House Sheet Metal Fabrication

Custom flashings and architectural detailing produced in our Burnaby shop for tighter tolerances and faster turnaround.

Commercial-Only Crews

Experienced commercial and strata crews — not residential subs — on every envelope, sheet metal and maintenance scope.

Consultant Documentation Standards

Hold-point inspections, daily reports and full QA/QC packages aligned to the envelope consultant of record.
