Buildup of Ice dams
Ice dams are flakes of icicles that hang off along the edges of your roofing. If the ice dam buildup on your roof is intense, you will see the ice dams while standing outside your house. However, don't wait for the ice dams to be visible use a ladder and go up the roof to inspect the presence of ice accumulation. Otherwise, call a professional to check if your roof has ice dam buildup.
If roof ventilation in your house is faulty, it will lead to poor heat circulation. As a result, snow and moisture on the roof melts and freezes irregularly causing the icicles buildup. Faulty ventilation can result from a damaged ventilation system or insufficient ventilation. Call a professional to fix any damages, add vents or replace your ventilation system.
