CERTIFICATIONS
An asphalt and gravel roof is a durable, proven solution.
Asphalt and gravel roofing is a traditional roofing solution, renowned for its robustness and durability . It is particularly suitable for commercial and industrial buildings with flat or very low-slope roofs, where resistance to weathering and climatic stresses is essential.
Composed of several layers of asphalt felt covered with gravel, this type of roof offers good protection against UV rays, shocks, temperature variations and snow accumulation .
THE ADVANTAGES
A commercial flat roof made of asphalt and gravel
An economical solution for large areas
Asphalt and gravel remains an attractive choice for large commercial roofs, thanks to its good value for money and the possibility of targeted maintenance.
Durability and mechanical protection
The layer of gravel protects the asphalt membrane from impacts, light traffic on the roof, hail, and temperature variations.
UV resistance
The gravel acts as a natural shield against the sun, reducing premature aging of the membrane.
Localized repairs possible
In the event of leaks or damage, it is often possible to repair the affected area without having to redo the entire roof.
Suitable for various types of commercial buildings
Suitable for office buildings, retail stores, warehouses, factories and institutional buildings.
The stages of an asphalt and gravel roofing project
1
TECHNICAL INSPECTION
Complete assessment of the existing roof, slope, condition of the structure and insulation, as well as identification of areas at risk of infiltration.
2
Preparing the support
Demolition or stripping of old layers as needed, repair of the bridge, adjustment of slopes and preparation of a solid base.
3
Installation of membranes
Application of the different layers of asphalt felt, according to the project specifications and the manufacturer's requirements.
4
Hot asphalt application
Pose de la couche d’asphalte chaud sur la surface, en veillant à l’uniformité et à la continuité de l’étanchéité.
5
Gravel application and leveling
Adding and distributing gravel on the still-warm asphalt to ensure mechanical protection and UV resistance.
6
Final inspection and cleaning
Complete verification of waterproofing, upstands, drains and finishing details, then site cleanup and warranty handover.
