What Makes A & B Roofing’s Flat Roof Installation Process Different?

We don’t treat flat roofing as simplified work. Our specialized installation procedures ensure your flat roof performs to manufacturer specifications and delivers decades of watertight protection.

Comprehensive Deck Assessment

We thoroughly inspect roof deck installation, verify proper slope for drainage, check structural support adequacy, ensure deck flatness meets membrane requirements, and confirm your foundation provides code-compliant support.

Critical Drainage Design

Flat roofs aren’t actually flat. We design and install proper drainage systems with minimum slope requirements, strategically positioned drains and scuppers, overflow protection, and water flow patterns that prevent ponding.

Premium Insulation Installation

We install high-performance rigid insulation boards that meet energy code requirements, provide proper R-values for Vancouver Island climate, create thermal barriers that reduce energy costs, and support membrane performance.

Expert Membrane Installation

TPO, EPDM, or modified bitumen membranes installed to exact manufacturer specifications. Our certified installers ensure proper seam welding, secure attachment methods, and weathertight performance across the entire roof surface.

Professional Flashing & Penetration Details

Parapet walls, HVAC curbs, roof drains, penetrations. We install custom-fabricated flashing and weatherproofing details that integrate seamlessly with your membrane system, preventing leak points before they develop.

Comprehensive Quality Assurance

Every installation undergoes rigorous inspection. We verify seam integrity, test drainage performance, check flashing connections, and ensure your installation meets BC building codes and manufacturer warranty requirements.
