Snow Buildup & Ice Dams on Roofs in Barrie, Orillia & Innisfil

Some of the most common winter roofing problems for homes in Barrie, Innisfil, and Orillia are buildup of snow and ice dams.

Why Snow Buildup Is a Serious Problem?
Roofs can hold thousands of pounds of weight in several snowstorms. Generally sloped residential roofs can experience high snow load, but low-slope and flat roofs especially sensitive.
Warning signs of dangerous snow accumulation include:
Sagging roof lines: An obvious indication that your roof is overloaded.
Creaking sounds in the attic: Sign of structural load on your roof.
Ice forming along roof edges: Often leads to ice dams.
Water stains on ceilings: It could indicate that your roof is leaking water.
Frozen or blocked gutters: Prevents proper flow and increases roof damage.
If you’re noticing any of these issues, it’s time to act before minor damage becomes a major repair bill.
What Causes Ice Dams?
Whenever heat escapes from your house and melts snow on your roof, ice dams are created. A dam develops when water comes down the roof and refreezes outer edges. Water can be eventually forced under the shingles and into the house as a result, leading to leaks, damage to your ceiling, and even the growth of mold.
Factors that increase ice dam risks include:
Poor roof insulation
Inadequate attic ventilation
Heavy or wet snowfall
Clogged gutters
