Winter poses significant challenges for homeowners, especially when it comes to protecting your roof from ice dams. Champion Restoration and Construction in Chantilly, VA, offers insights into the causes, dangers, and prevention of ice dams to help you safeguard your home.
An ice dam is an accumulation of frozen water at the edge of the roof that prevents melting snow from draining off the roof. This can cause serious damage to the roof and home structure.
Causes of Ice Dams
Poor Attic Ventilation
- Heat Escape: Warm air from the house rises into the attic, heating the roof and causing snow to melt.
- Refreezing: Melted snow flows to the colder roof edge, refreezing and forming a dam.
Dangers of Ice Dams
Structural Damage
- Gutter Damage: Ice dams can tear off gutters.
- Shingle Damage: Ice can loosen shingles, causing leaks.
- Water Damage: Water backing up under shingles can leak into the home, damaging walls, ceilings, and insulation.
Mold and Mildew
- Moisture Build-up: Persistent moisture can lead to mold and mildew growth in the attic and on walls, posing health risks.
Prevention of Ice Dams
Gutter Maintenance
- Clean Gutters: Regularly clean out gutters to prevent blockages that can exacerbate ice dams.
- Replace Old Gutters: Ensure gutters are in good condition to handle winter weather.
Proper Insulation
- Attic Insulation: Insulate the attic to prevent heat from escaping and warming the roof.
- Ventilation: Install ridge and soffit vents to circulate cold air under the roof.
Sealing Openings
- Attic Hatch and Vents: Seal attic hatches and vents to minimize heat loss.
- Exhaust Ducts: Ensure kitchen, bathroom, and dryer vents lead outdoors and not into the attic.
Advanced Solutions
- WeatherLock® Flex: Use products like Owens Corning WeatherLock® Flex to provide an additional waterproof barrier, especially in vulnerable roof areas.
