Roofing Ventilation

Appropriate attic ventilation is an important consideration when installing a new roof or repairing an existing roof. Roofing vents are the small, inconspicuous box or dome-shaped portions of a roof you can easily see from the street or your yard. Most roofing vents are placed on the back side of a roof to maintain aesthetic curb appeal from the street. These small but important components of a roofing system are critical to the maintenance of your roofing materials and the service that they can be expected to provide. Toms River roofing can assist you with assessing and addressing any roofing ventilation needs you may have.

Heat is destructive to roofing materials and can cause asphalt shingles to age quickly and become brittle. This aging process can lead to cracking, curling and breaking of the shingles, which can cause roof leaks and urgent repair needs. Preventing the premature aging of roofing materials is typically as simple as providing adequate ventilation in your attic space. Small vents in the roof and soffits that open to the outdoors allow warm air to rise and exit the roof, keeping the space and the roofing materials at a cooler temperature. Because warm air naturally rises, no fans or mechanical ventilation systems are typically required, although they are a possible option should your roofer recommend their use to assist with the cooling of your attic space.

An enclosed attic space can heat up very quickly in the heat of summer. When the roof is exposed to the hot sun, the roofing materials and attic space heat up like a greenhouse. Additionally, heat from the rest of the home will rise and fill the attic space, making the temperatures extreme in some cases. If the hot air has no route to escape the attic, the roofing materials, roof structure and items in the attic will be exposed to intense heat, which can lead to the breakdown of plastics, asphalt shingles and other roofing materials.

You should consult a roofing professional if you believe your attic has inadequate ventilation; a roofer can evaluate the attic space and make a recommendation for any necessary changes. Ventilation is typically fairly simple for a roofer to install by cutting small holes in your roof and installing the weatherproof ventilation units. The cosmetic appearance of your roof will change very little, and your roofer will place the ventilation in inconspicuous places that will also provide adequate airflow.

What temperature is correct for my attic?

There is no correct temperature for your attic as it can vary depending on the attic space and the climate of the geographical area. However, if your attic is regularly a great deal warmer than your home or outdoor temperatures, you may need to evaluate the need for improvement in the ventilation system.
