Ice & Water Shield Installation in Ottawa

The Ice Dam Problem

Ottawa's freeze-thaw cycles create ice dams on roofs. Melting snow runs down the roof, then refreezes at the eaves, creating a dam. Water backs up under shingles and enters the attic. Ice & water shield catches this water and directs it down and away.

Why It's Essential in Ottawa

• Ottawa experiences repeated freeze-thaw cycles
• Heavy snow loads cause ice dam formation
• Water damage from ice dams is common without protection
• Insurance may not cover preventable ice dam damage
• Proper ice shield prevents interior damage

Ice & Water Shield Works Best With

• Proper Ventilation: Keeps roof cold, prevents melting
• Adequate Insulation: Prevents interior heat loss that causes melting
• Quality Gutters: Channels water away after it melts
• Proper Drainage: Ensures water flows away from foundation

Integrated System Approach

Ice & water shield is one component of a complete ice dam prevention system. Without proper ventilation and insulation, even the best ice shield has limitations.
