Winter in Boise is milder than much of Idaho, but The Treasure Valley still delivers enough freeze-thaw cycles, ice events, and occasional heavy snowfall to stress roofs that aren't prepared. Most winter roof problems are preventable with fall preparation and a few basic monitoring habits.
Managing Snow Load
Most Boise homes are engineered to handle the snow loads typical for Ada County. Problems arise during unusually heavy snow seasons or on older homes with roof structures that have been compromised. Signs that snow load may be becoming an issue include cracking or popping sounds from the roof structure, doors or windows that suddenly become difficult to open or close, or visible sagging of the ridge line when viewed from outside.
What Not to Do
Well-meaning homeowners cause more winter roof damage trying to fix ice dams than the dams themselves cause. Specifically avoid chipping at ice with a pick, axe, or hammer. Avoid using a pressure washer on ice formations. Avoid applying rock salt directly to the roof, as it accelerates corrosion on gutters and flashing. Never get on the roof in any icy condition.
When to Call During Winter
Call immediately if you have active water intrusion into living space. Emergency tarping can prevent interior damage from spreading while a permanent repair is scheduled. Blue Goat Roofing responds to emergency calls throughout The Treasure Valley year-round.
