Your roof is one of the components that make up your home’s thermal envelope. It plays a vital role in ensuring energy efficiency by sealing in the heated or cooled air and keeping outdoor temperatures out. With adequate ventilation, the heat inside the attic doesn’t build up and wreak havoc on your indoor comfort.
The Effects of Roof Overheating
Residential roofs receive excess heat on sunny days, especially during the summer months. As a result, the attic can get hot, reaching temperatures of up to 160 degrees. Without ventilation, heat can’t dissipate, causing damage to various roof components. Asphalt shingles, for instance, can buckle, crack or become brittle. Some parts may also lose their adhesion because of too much heat.
It gets worse, however, once moisture enters the equation. As your air conditioning system provides cool air in your living spaces, condensation begins to form inside your hot attic. The presence of moisture can expedite mold and mildew growth as well as rot on your roof’s rafters, joists and other wooden components. A damp, undisturbed area like the attic also offers a place of refuge for many critters, including rodents and insects.
An overheating roof can also impact how your air conditioning system works to provide consistent indoor temperatures. You might think your cooling equipment is doing its job, but in reality, it is exerting too much effort to keep you comfortable. This can affect your equipment’s efficiency as well as your home’s energy consumption.
The Importance of Roof Ventilation
Adequate roof ventilation helps avoid these issues. Soffit and fascia vents are installed along the eaves or underside of your roof. Their function is to help facilitate the entry of fresh air into your attic. Your roof must also have exhaust vents, preferably on the ridge or the part where two roof planes meet, to allow hot, moist attic air to escape.
