How should you prevent ice damming this Spring? Follow these tips:
-Keep the attic well ventilated.
-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 to minimize the amount of heat rising into the attic from below.
-Use a roof rake to clear the snow above the gutter. Clear about one meter above the gutter to allow water to drain freely into the gutter.
-Next year you can try to 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.
