The Science Behind Ice Dams
As winter blankets New Hampshire with its characteristic snow, many homeowners face the challenging issue of ice dams. These problematic formations can cause significant structural damage to your roof and interior walls if left unchecked.
What Causes Ice Dams?
Ice dams form through a three-step process:
1. Heat escapes through your roof, warming the surface
2. Snow melts and runs down toward the eaves
3. The water refreezes at the colder roof edge, creating a barrier
Prevention Methods
Professional roofers recommend several effective prevention techniques:
• Proper attic insulation (R-60 for New Hampshire climate)
• Adequate ventilation systems
• Installation of heat cables in problem areas
• Professional snow removal after heavy storms
Critical Warning Signs
Watch for these indicators:
– Icicles forming along gutters
– Ice buildup on roof edges
– Water stains on interior ceilings
– Peeling paint near roof lines
Long-term Solutions
Preventing ice dams requires a comprehensive approach to roof maintenance. Professional evaluation can identify vulnerable areas before winter arrives, potentially saving thousands in repair costs.
Regular maintenance and proper insulation are your best defenses against ice dam formation in our challenging New Hampshire climate. A properly maintained roof system helps ensure your home stays protected throughout our harsh winter months.
Remember, addressing ice dams promptly can prevent extensive damage to your roofing system and interior spaces. Professional inspection and maintenance are crucial investments in protecting your home’s integrity during winter weather.
