Elastomeric Membrane Roof Repair

Even the most durable membranes can show signs of wear over time. Harsh weather, UV rays, or aging seams can lead to cracks or blisters in your elastomeric roof. Our specialists act quickly to restore membrane integrity and prevent leaks.



  • Targeted inspection to identify weakened areas
  • Application of modified bitumen coatings or localized seam repairs
  • Hot-welded repairs for maximum waterproofing

TPO Roof Repair

TPO is a modern material, but it can still suffer damage—punctures, weakened seams, or air bubbles. Our team uses precise heat-welding techniques to restore your membrane without compromising its performance.


  • Detection of damaged or delaminated areas
  • Cleaning, preparation, and heat-welding of defective membranes
  • Application of specialized sealants for a long-lasting finish

Built-Up Asphalt and Gravel Roof Repair

Asphalt and gravel remains one of the most common roofing systems in Montreal. But over time, this type of surface may require repairs—cracks in the asphalt, gravel loss, or surface deformation. Our approach helps extend the life of your multilayer roof.


  • Surface inspection to detect signs of wear
  • Localized asphalt applications or replacement of damaged felts
  • Redistribution of protective gravel for even coverage

Shingle Roof Repair

Shingle roofs exposed to wind, rain, or sun can deteriorate quickly. Missing or cracked shingles can lead to water infiltration. We ensure fast, precise replacement to maintain your roof’s performance.


  • Identification of damaged areas and missing shingles
  • Replacement of broken elements and reinforcement of fasteners
  • Application of sealant to prevent future leaks
