When roofing professionals point out thick ice buildup along the edge of a roof it is not about the ice itself. It is about what is happening underneath the shingles. This type of buildup is one of the clearest signs of ice dams which are a leading cause of winter roof damage across the GTA.
What Ice Dams Really Mean for Your Roof
Ice dams form when snow melts higher up on the roof and refreezes at the colder roof edge. As ice builds up it creates a barrier that prevents water from draining properly. That trapped water has nowhere to go except back under the shingles where it can seep into the roof system. Over time this can lead to leaks damaged insulation stained ceilings and interior water damage.
Large icicles and thick ice along the eaves are not just cosmetic issues. They indicate ongoing moisture problems that can worsen quickly during freeze thaw cycles.
Why Ice Dams Are So Common After Snowstorms
After major snowfalls followed by fluctuating temperatures roofs experience uneven melting. Heat loss ventilation issues or insulation gaps can accelerate this process. As water repeatedly melts and refreezes ice dams grow thicker and the risk of leaks increases. Many homeowners do not notice the damage until water appears inside the home.
The Importance of Early Detection
Catching ice dam issues early can prevent extensive repairs. Addressing the problem before a full thaw helps protect ceilings walls and attic insulation from moisture damage. Professional inspections allow roofers to identify the cause of ice dams and recommend safe solutions rather than temporary fixes.
