How to Prepare Your Roof for Winter in Montreal

Each year, the first snowflakes remind homeowners in Greater Montreal that it is time to think about their roof. Pre-winter inspection and preventative maintenance can prevent costly leaks, ice, and emergency repairs.

Winter in Quebec is putting roofs to the test, especially when they have not been maintained for several years. Here's how to protect yours before the cold sets in.

1. Inspect the roof before the snow

Before the roof is covered, a visual inspection can detect hidden problems. Look for raised shingles, cracks in joints, and signs of wear and tear around chimneys and skylights.
An experienced roofer can also check the condition of the membrane and the solidity of the structure. A small repair done on time can avoid infiltration all winter long.

2. Clean gutters and drains

Leaves, pine needles, and debris often block gutters. If the water no longer drains properly, it will freeze and form ice dams.
Simple cleaning in the fall ensures good drainage of water and reduces the risk of overflow.
It is also time to check that the downspouts are not obstructed.

3. Check attic insulation and ventilation

Poor attic ventilation causes moisture to accumulate and ice to form on the roof. In Montreal, it is one of the main causes of premature roof deterioration.
Good air circulation and adequate insulation keep the roof dry, avoid temperature variations and extend the life of the coating.

4. Clear debris and branches

Branches that touch the roof can damage the shingles and trap snow. Before winter, they should be pruned and any debris removed from the roof.
It also reduces the risk of accidents or falling branches during storms.

5. Provide a roof snow removal service

Snow accumulation is a considerable burden, especially for flat or low-sloped roofs. Excess can cause cracks, seepage, and even subsidence.
Hiring a professional snow removal service is the safest solution. Trained roofers know exactly how much snow to remove without damaging the coating.
