What is Ice Damming?

As the winter season blankets the landscape in a serene white, it also brings along a hidden menace to your home's roof known as "ice damming." This often-overlooked issue can wreak havoc on your roof, leading to costly repairs and damage to your property. 

In this blog post, we will dive deep into understanding what ice damming is, its causes, effects, and most importantly, how you can prevent it. By the end of this article, you'll have a comprehensive grasp of this winter headache and learn how proper insulation, such as spray foam insulation and the expertise of Ottawa Insulation, can come to your rescue.

1. What is Ice Damming?

Ice damming is a phenomenon that occurs during the winter when snow on your roof melts and then refreezes near the roof's edge. This ice buildup forms a barrier, preventing further snowmelt from draining properly. The result? Water backs up behind this ice dam, potentially infiltrating your home, causing leaks, and damaging your roof's structure.

2. Causes of Ice Damming

Understanding the causes of ice damming is essential in preventing it. Several factors contribute to the formation of ice dams, including:

(i). Inadequate Insulation

Poor insulation allows warm air to escape from your home's interior, heating the roof and causing snow to melt.

(ii). Uneven Roof Temperatures

Inefficient attic ventilation can lead to varying temperatures on your roof, promoting uneven snowmelt.

(iii). Snow Accumulation

Heavy snowfall followed by freezing temperatures can accelerate ice dam formation.

(IV). Roof Pitch

Low-slope roofs are more prone to ice damming due to their reduced ability to shed water.

3. Effects of Ice Damming

Ignoring ice damming can result in severe consequences for your home. Some of the common effects include:

(i). Roof Damage

Ice dams can lift shingles, causing structural damage and reducing the roof's lifespan.

(ii). Interior Water Damage

Leaks caused by ice damming can damage your ceilings, walls, and insulation.

(iii). Mold Growth

Moisture from ice dams can create an ideal environment for mold growth, posing health risks.

(iv). Increased Energy Bills

Poor insulation and ice damming can lead to heat loss, causing higher energy consumption and costs.

4. Preventing Ice Damming

Preventing ice damming starts with proper insulation and ventilation. Here are some steps you can take:

(i). Insulation Upgrade

Invest in high-quality insulation, such as spray foam insulation, to maintain a consistent temperature on your roof.

(ii). Seal Leaks

Identify and seal any gaps or leaks in your attic to prevent warm air from escaping.

(iii). Roof Ventilation

Ensure proper attic ventilation to regulate the temperature and reduce snowmelt.

(iv). Snow Removal

Safely remove excess snow from your roof to minimize ice dam formation.
