Components of a Flat Roof


Roof Deck

As the skeleton of the roof, the deck is made of boards or planks that provide the base.


Vapour Barrier

The vapour barrier works alongside the insulation, keeping the surface dry and cool and protecting it from heat and moisture build-up.



True to its name, the insulation absorbs and retains sunlight, helping to reduce the exchange of heat. Insulation helps to keep your building cool in the summer and warm in the winter.



The protection board is installed over the the insulation, to provide a smooth surface for roofing membranes.


Base Layer

The base layer is the first of the outer roof layers, cover the entire surface area of the building.

Top Layer

Granulated Top Layer

A granulated top layer is the final layer of the membrane. It protects from UV rays and offers support for foot traffic and storage.

If you do require work, your business does not have to stop operations.
