A roof is a major investment. In Montreal, harsh winters and flat roofs call for an experienced, properly licensed contractor.

Require the RBQ licence

Every roofing contractor in Quebec must hold a licence from the Régie du bâtiment du Québec (RBQ). Verify it and confirm that liability insurance is current.

Compare quotes

  • Get at least three detailed written quotes.
  • Compare the proposed materials (elastomer membrane, shingles, TPO).
  • Ask about the warranty length on both materials and labour.

Frequently asked questions

When should you redo your roof?

Watch for leaks, lifted shingles, or a cracked membrane. Most roofs last 20 to 30 years depending on the material.

What is the best season?

Late spring through fall is ideal. Emergency work is still possible in winter but often costs more.
