Why Are Attic Insulation So Important?
The Main Source of Heat Loss
Under Toronto’s climate conditions, the attic is the most significant source of heat loss in a home. Warm air naturally rises—if your attic is under-insulated, a large portion of your expensive heating literally escapes through the roof, forcing your heating system to work much harder.
Ice Dam Prevention in Winter
Proper attic insulation helps prevent snow on the roof from melting and refreezing, which can form dangerous ice dams. Ice dams not only pose safety risks and damage roof structures but can also cause leaks and lead to costly repairs.
Structural Protection & Mold Prevention
The right insulation, combined with proper ventilation, helps stabilize roof temperature and prevents damage caused by extreme temperature fluctuations. It also reduces moisture buildup, lowering the risk of mold and mildew formation.
