Roof with multi-ply asphalt and gravel membrane

Specialists in flat and low-slope roofing in the greater metropolitan area

Exceptional durability

Thanks to its multiple layers of bituminous felt and its gravel protection, this type of roof can last around 20 years with proper maintenance.

Excellent waterproofing

The layering of asphalt creates a waterproof barrier that is highly resistant to water infiltration, making it ideal for flat roofs.

Fire and weather resistance

The gravel on the surface protects the membrane from UV rays, temperature fluctuations, hail, and acts as a natural flame retardant.

What is a multi-ply asphalt and gravel roof?

The multi-ply asphalt and gravel roof is a traditional and proven solution for flat or low-slope roofs. This type of roofing consists of several layers of bituminous felt soaked in hot asphalt, covered with gravel to protect the membrane from UV rays, weather, and thermal shocks.

Available in gray and black

How is a multi-ply asphalt and gravel roof installed?

At LK Toitures, the installation of a multi-ply asphalt and gravel roof follows a proven process that ensures the performance and longevity of your roof. Here are the main steps of our process:

1. Inspection and surface preparation
First, our experts inspect the existing structure to detect any defects, moisture areas, or irregularities. The surface is then cleaned, leveled, and prepared to receive the membrane layers.

2. Application of bituminous felts
Several plies of saturated felt (typically 3 to 5) are laid in alternating layers, creating a solid base. Each layer is carefully aligned to ensure uniform coverage.

3. Hot asphalt application
Hot asphalt is applied between each layer to fuse them together and create a waterproof membrane. This step is crucial to ensure the system’s watertightness.

4. Installation of the finishing layer
Once the layers are sealed, a final layer of asphalt is applied, followed by the addition of gravel. This gravel protects the roof from UV rays, thermal shocks, and erosion.

5. Final inspection and site cleanup
A complete quality check is carried out to ensure the roof is properly installed and meets all standards. The site is then cleaned, leaving the area tidy and safe.

The multi-ply asphalt and gravel roof requires maintenance of the drains and removal of debris to protect the membrane.

Justin Hugues-Deraiche – Into Inc

The service was impeccable! Nothing to complain about, my technician had only positive feedback about the service team on-site.

Xavier Sylvain-Salvador – Ingétec

As far as I’m concerned… Quote, appointment, and report after the visit: A-1. Scheduling the work appointment – A-1. As for the day of the work, I received no feedback, so I presume it’s also A-1… If there are any comments, I will let you know. Invoice and report, A-1. Keep it up! (Note: getting your quote report so quickly after Dany’s visit is really awesome!)

Big thanks again for the great work! I really appreciated working with your company. This certainly won’t be the last time we get in touch.

Thank you for your intervention. The work was well done, and the site and parking area were clean as well. I really appreciate it, especially since we had to ask the neighbor for permission to use their parking space. Communication was good, as were customer service and work quality—everything was excellent.
