Ice Buildup On The Roof

Acceptable Performance/Condition
Ice and icicles are a natural occurrence on roofs.

Warranty
None.
Damage caused by improper maintenance is not covered by the warranty.

Action
The builder is not required to take any action.

Remarks
Ice dams and icicles occur when the roof surface is warm enough to melt the snow but the air temperature is cold enough to re-freeze the melt water. Natural weather patterns, building exposure, roof design and elevated attic temperatures, due to both the insulating effects of snow accumulation on the roof and air leakage from the interior of the building, can contribute to ice forming on roofs. Professional removal of buildups of ice and snow can help reduce the likelihood of water leaks.
See section 5.5 Roof or Flashing Leaks for water leakage resulting from ice dams.
This condition is warranted only where there is a demonstrated Building Code violation or a defect in work or material supplied by the builder.
