Attic Ventilation

In the days before the 1960s when prefabricated roofing trusses were first mass-produced, many houses were built with pitched roofs. The space between the pitched roof and the ceiling of the top floor in the building was called an attic. Attics play an important role in both the ventilation of your home and the ventilation of your roof. A Toms River roofing specialist can help you make sure that the ventilation in your attic is sufficient to safeguard against high utility bills and protect against the shingle damage that can occur when hot air is trapped in your attic.

Hot air rises, so during the warmer months, hot air will naturally migrate to the upper rooms in your house and especially into your attic. When it collects beneath your roof, this hot air actually has the potential to cause your roof shingles to buckle and curl. Additionally, when the sun beats down on the surface of your roof, more heat will move into your attic through the process of conduction unless your attic is ventilated well enough to allow the escape of hot air.

When your attic isn’t ventilated properly, more heat is retained in your house during summer, which means that you may find yourself running your air conditioning system more often. This is not only costly, but it’s also undesirable from an environmental point of view.

During the colder months, the heat generated by your temperature control system also migrates to your attic, carrying moisture with it. This moisture may condense when it comes into contact with colder roof sheathing, forming droplets that have the potential to damage any insulation they come into contact with. Sodden insulation is a less effective barrier against the cold, so your heating costs may skyrocket. Adequate attic ventilation can prevent this phenomenon by regulating the exchange between warm interior air and cold exterior air.

Roof vents are one of the most popular methods for ensuring that your attic stays properly ventilated. Air intake vents that allow outside air to enter your attic are usually located along the bottom edge of your roof or under your roof’s eaves. Exhaust vents, on the other hand, provide a conduit for interior air to be pushed outside, and they’re often coupled with fans. Exhaust vents are typically positioned along a roof’s highest points. An experienced roofing contractor can help you determine the optimal placement of roof vents if you own a home with an attic.

Roofing term provided by Fortified Roofing, Toms River roofing contractors:

Roof vents

Roof vents are openings that promote the exchange of interior and exterior air inside an attic. They enhance the comfort of your home by allowing hot air to escape during the warmer months. They also prevent water from condensing on insulation during the colder months, which reduces the effectiveness of insulation and can also lead to mildew infestations.

Toms River roofing contractors from Fortified Roofing answer a question:

Where should roof vents be placed for optimal attic ventilation?

The roof ventilation scheme you use will vary depending on the design of your roof, but the rule of thumb is that intake vents are generally positioned along the bottom edges of the roof or under the eaves while exhaust vents are placed along the highest point of the roof.
