Ice dams are typically caused by uneven heat loss from your home in wintry conditions such as snow, heat melting the snow, and cold temperatures re-freezing melted snow. The heat is typically caused by inadequate attic insulation or from warm air seeping into the attic from living spaces below. This causes the roof to warm above freezing temperature, which allows snow to melt and then re-freeze before it reaches the roof’s edge. If this cycle repeats over and over, an ice dam forms and water collects behind it. As the water pools, it backs up under your roofing material and can cause expensive water damage.
Here are our top 6 things you can do to prevent Ice Dams from forming on your roof this spring!
- Keep the attic well ventilated. One-third square metre of free ventilation opening is recommended for every 45 square metres of attic space.
- Seal air leaks to prevent warm air leakage from plumbing vents, junction boxes from ceiling fixtures and attic hatches.
- Keep the attic floor well insulated (between 40 and 56 centimetres of insulation) to minimize the amount of heat rising into the attic from below.
- Clean leaves and other debris from gutters before the first snow. This will help prevent ice buildup in your gutters. Also consider using an ice shield under your shingles when your house is getting re-roofed.
- Use a roof rake to clear the snow above the gutter. Clear about one metre above the gutter to allow water to drain freely into the gutter.
- Consider hiring an energy specialist to evaluate the performance of your home, and recommend some things you can do to minimize energy waste.
Though your homeowners insurance policy provides the protection that you need in the event of a loss such as a fire or burglary, your policy can only pay for items that you can document. In order to ensure that all your prize possessions will be replaced, you should conduct a home inventory so you have a finite record of everything that you own. This inventory will assist you in determining which items were destroyed or stolen.
