Ventilation before snowfall
Balanced attic ventilation is the best ice dam prevention. If your roof is due for replacement, address ventilation during the project — not after damage occurs.

Winter Roof Preparation in Ontario
How to prepare your roof and attic for Ontario winters — ventilation, ice dam prevention, and emergency planning.
Trim overhanging branches
Ice-laden branches snap under weight and puncture shingles. Clear branches 6+ feet from the roofline before the first heavy snow.
Know your emergency plan
Locate your main water shutoff. Keep Trident's number saved: (226) 680-0996 for 24/7 emergency tarping if a leak develops during a storm.
Do not climb on icy roofs
Winter inspections should be done from the ground or by a professional with proper safety equipment. Ice and steep pitches are extremely dangerous for homeowners.
