Severe ice build-up
When snow on the roof is melted by heat escaping from the attic, and the melted snow re-freezes, this causes ice damming on the roof of your home. Eventually water can start leaking in, creating a ton of damage.
Thick icicles on roof
Thick icicles hanging from roof eaves could indicate a serious ice dam problem.
Huge icicles forming around the gutters and eaves can prevent the flow of water, causing it to build up and break your gutters and leak water into your home.
Heat escaping from attic forms ice dams
This snow-covered roof may look nice, but icicles are a sign of energy loss through the attic, which could be costing the homeowner a lot of money in fuel and heating costs.
Icicles hanging from gutters
Do you have icicles hanging from your gutters? When the upper area of the roof warms up and melts the snow, the cold eaves freeze the water runoff, forming icicles like the ones seen here.
Melting snow causes damage
When more water accumulates behind the ice dam, the water can flow over the dam to form icicles along the edge of the roof.
Big icicles cause severe damage
The icicles hanging from this roof are so big they are touching the satellite dish! Big icicles like this can cause severe damage to the exterior of your home and lead to physical injury from falling ice.
Roof architecture can lead to issues
The architecture of this roof has caused the runoff from the melting snow to form thick icicles at the corner of the roof.
Heavy snowfall and ice dams
Ice dams typically form after a heavy snowfall. The only way to prevent the problem is to fix the source - poor attic insulation & ventilation.
Take a look at how large these icicles are. A huge chunk of falling ice can cause serious physical injury or property damage.
Small icicles are common
Small icicles on the roof are normal, but it's important to watch for signs of ice damming to prevent damage to your home.
Uneven snow melt
If there are areas of your roof where the snow has melted and others that haven't, this is a sign of inadequate insulation in your attic.
Sun's heat melting snow on roof
When the heat from the melts the snow on the roof, this water can leak on the walkway below and cause a slipping hazard. The overflow can also re-freeze and form icicles, creating the potential for roof damage and leaks.
