When Should You Repair or Redo Your Roof in Montreal? Signs You Should Not Ignore

In Montreal, the climate is putting roofs to the test. Between the harsh winters, the spring rains and the great variations in temperature, the materials wear out much more quickly than elsewhere. However, many owners wait until they have an infiltration before reacting.
Knowing how to recognize the signs of a roof at the end of its life allows you to avoid costly repairs and preserve the value of your home.

1. Signs that it is time to act

A well-maintained roof can last 20 to 25 years, but there are several signs that indicate a need for repair or repair.

  • Asphalt shingles that peel or discolour
  • Accumulation of granules in gutters
  • Traces of humidity on the ceiling or in the attic
  • Light leaks after rain or snow melt
  • Visible roof deformation or cracked joints

As soon as any of these symptoms appear, an inspection is essential. A qualified roofer can confirm whether a simple repair is sufficient or if a complete overhaul is preferable.

2. Repairing or redoing the roof: how to decide

The right decision depends on the age of the roof, its material, and the extent of damage.

  • Under 10 : a local repair is often sufficient.
  • 10 to 20 years : a professional diagnosis is required to determine the durability of the coating.
  • Over 20 years : a complete renovation often becomes the most profitable solution in the long term.

In Montreal, frequent freezing and thawing accelerate the deterioration of shingles and joints. It is better to act at the first signs of wear and tear than to wait for an infiltration.
