Roof Replacement in Montreal and on the South Shore
What Is Roof Replacement?
Roof replacement involves tearing off the old membrane and installing a new covering on the existing substrate. Unlike a simple repair that targets a localized problem, replacement brings the entire surface back to like-new condition. ML Pro Toitures performs flat roof replacement throughout Montreal and on the South Shore, for residential, commercial, and institutional buildings.
Is your membrane past its prime?
Let's start from scratch.
When Is Roof Replacement Necessary?
Certain signs indicate that a repair is no longer enough and that a full replacement is required:
Membrane that is blistered, wrinkled, or delaminated across the entire surface
Repeated water infiltrations despite previous repairs
Ceramic granules completely worn away or absent
Seams and flashings deteriorated along the entire perimeter
Membrane at the end of its service life
How Is a Roof Replacement Performed?
1
Tear-off of the Old Membrane
The existing membrane, flashings, and any deteriorated surface material are removed to expose the wood substrate.
2
Substrate Preparation
The decking is inspected a second time once it is fully exposed. Damaged sections are repaired and the surface is cleaned and primed to receive the new membrane.
3
Installation of the New Membrane
The new membrane (elastomeric, TPO, or EPDM depending on the building and the client's needs) is installed according to manufacturer standards to ensure the validity of your warranty.
4
Sealing of Flashings and Details
Every seam, drain perimeter, chimney, and flashing is carefully sealed to eliminate any potential point of water infiltration.
5
Final Inspection and Cleanup
The entire surface is inspected to confirm waterproofing integrity. The site is left clean before our team departs.
