Why Ice Dams Form on Toronto Roofs and How to Prevent Them?

In winter, Toronto offers a picturesque view of snow-covered rooftops. Apart from good looks, it brings a common challenge for homeowners: ice dams. If not addressed promptly, these dams cause significant damage to their home’s roofing system. This article will explain why ice dams form, their impact on your roof, and effective roof ventilation solutions for preventing ice dams, with insights from Ace Roofing Toronto.

What are Ice Dams

The ridges that form along the edge of a roof, preventing melting snow from draining off, are called ice dams. This trapped water can seep under shingles and into your home, causing extensive damage. The first step in preventing damage is understanding the causes of ice dam formation.

Why Do Ice Dams Form?

Due to uneven roof temperature ice dams occur. Snow melts on your roof as the heat escaping from your home warms the roof’s upper sections, The melted snow flows down to the colder edges, where it refreezes, forming ice dams. Key factors contributing to ice dam formation include:

  1. Inadequate Roof Ventilation: Because of poor ventilation warm air deposits in the attic,  heating the roof.
  2. Improper or Poor Insulation: Warm air escapes from the living area into the attic due to the gaps in insulation.
  3. Clogged Gutters: Due to blockage of gutters drainage becomes improper and exacerbates ice dam formation.

Impact of Ice Dams on Shingles and Roofing Materials

Ice Dams can wreak havoc on your roofing system. The trapped water can infiltrate under shingles, leading to:

  1. Shingle Damage: Shingles can warp, crack, or lose granules due to prolonged exposure to moisture.
  2. Roof Deck Deterioration: Water seepage weakens the roof deck, increasing the risk of structural damage.
  3. Interior Water damage:  Inside your home stains appear on your ceiling, paint peels off from walls, and mold can grow due to water seepage.

Ice Dams’ Damage Signs of Your Roof 

Identify these signs early on your roof to save you from costly repairs: Look for the following signs:

  1. Water Stains: Water infiltration makes discolored patches on ceilings or walls.
  2. Icicles: Although they look charming, large icicles often signal ice dam formation.
  3. Sagging Gutters:  The weight of ice dams can pull gutters away from the roofline.

Roof Ventilation Solutions for Preventing Ice Dams

Proper roof ventilation is essential to keep the roof temperature consistent. Ace Roofing Toronto recommends the following solutions:

  1. Ridges Vents: Ridge vents allow warm air to escape from the attic efficiently which are installed along the roof’s peak.
  2. Soffit Vents: These vents draw cool air from outside which balances the attic temperature.
  3. Gable Vents: These vents are positioned on the side wall of the attic to improve cross-ventilation.
