How Proper Roof Ventilation Can Save You on Cooling Costs
It has been a warm summer so far but most homeowners don’t give much thought to roof ventilation, but it plays a huge role in your home’s comfort and energy efficiency, especially during Toronto’s hot summer months. At Top Roofers, we regularly help homeowners cut cooling costs by upgrading or correcting poor ventilation in their roofing systems. Here’s how it works.
What Does Roof Ventilation Actually Do?
Proper roof ventilation is essential because it allows hot, humid air to effectively escape from your attic space. Without adequate ventilation, your attic can quickly become like an oven, trapping excessive heat that then radiates down and warms the rest of your home. This added heat forces your air conditioning system to work much harder to maintain a comfortable indoor temperature, especially during intense heat waves and hot summer days that we often see in the City of Toronto.
Signs Your Roof May Have Poor Ventilation:
Your upper floors are hotter than the rest of your house.
Cooling bills spike during the summer.
Shingles are curling or blistering.
Mold or mildew is found in your attic.
How Ventilation Reduces Cooling Costs:
When air circulates properly through your attic space, it effectively prevents heat buildup, which in turn reduces the need for excessive air conditioning during warmer months. This improved ventilation also helps extend the lifespan of your shingles by minimizing heat damage and prevents potential moisture problems such as mold and rot, keeping your roof structure healthy and durable for years to come.
Types of Roof Vents We Install:
Ridge vents (run along the roof peak)
Soffit vents (under the eaves)
Gable vents (in roof ends)
Powered vents (for problem areas)
Our recommendation is that if your home is over 10 years old and you’ve never had your ventilation assessed, now is the ideal time. A quick inspection can reveal minor issues that prevent costly problems down the line.
