Your roof.
Designed to work together.
A clear look at the components, so you know what your estimate should cover.
Every component
has a purpose.
From the deck to the surface, these are the five functions to address in your project.
White TPO membrane
The weather-facing surface. Seams are heat-welded according to the selected system.
Cover board
A suitable surface for the membrane, selected for the system requirements.
Insulation
Thickness, strength and slopes are determined for the project.
Vapour control
Its position and composition depend on the building and assembly.
Roof deck
The structural substrate is assessed and required repairs are identified before installation.
Functional overview, not to scale. Composition, layer order and attachments are adapted to the building and selected system.
Careful seams.
Attention at every connection.
Heat-welded seams, parapet upstands, drains and pipe penetrations need to work together. Surface preparation and weld checks are essential to a quality installation.
- Compatible materials
- Drain and penetration detailing
- Drainage considered in the assembly
A surface that
reflects sunlight.
A white membrane reflects part of the sun’s radiation and can reduce surface heating. Results depend on the product, its condition and the building.
In Montreal, material and permit requirements vary by borough and scope of work. Check the rules for your address before choosing the assembly.

Straightforward answers.
How is the attachment method selected?
The substrate, wind exposure and manufacturer requirements guide the selection. Mechanical attachment or an adhered system must be designed for the complete assembly.
Does a white roof eliminate maintenance?
No. Drains, seams and details still require inspection. Debris and defects should be addressed following the applicable recommendations.
What should the estimate specify?
Roof covering, preparation, insulation, attachment, connections, debris removal and exclusions. Ask about the terms of any warranties offered.
