Why Attic Ventilation & Insulation Are Important in the Summer

When it comes to home improvement work, insulating and ventilating your attic isn’t one of the more exciting projects. Attics aren’t really ever seen by homeowners, and you probably don’t use yours on a regular basis, so it’s easy to lose sight of of your attic’s condition—but it’s also crucial that you don’t neglect your attic.

Adequate attic ventilation and insulation can save you a tremendous amount of energy, and it lowers your Montgomery and Bucks County home’s utility costs not only in the winter months, but in the summer as well. Here are a few of the reasons that it’s so important to keep these parts of your attic in great shape:

The Importance of Attic Ventilation and Insulation

It’s important that you have both insulation and ventilation in your attic. Your attic should be able to keep warmth in while also allowing cool air to flow through it, even if that seems counter-intuitive at first. This is very important for your roofing during the winter months, when colder air needs to be kept in the attic to prevent ice dams from forming and causing serious problems for your roofing. Sealing air leaks and insulating the attic will also help to keep condensation from forming and causing moisture damage.

Attic ventilation and insulation are just as crucial during the summer months when cooling your home is a priority:

  • When your attic is properly ventilated, the extra hot air is pushed out of the attic, where it naturally rises to as it gets hotter.
  • The insulation works to block the transfer of heat from sunlight.

This keeps your Montgomery and Bucks County home more energy efficient throughout the hotter parts of the year, and it also helps to protect your roof’s shingles and help them shed moisture.

Attic Ventilation and Insulation Tips

  • Use rafter and soffit vents to promote adequate ventilation in the attic.
  • If it gets very hot, installing attic fans to cool the attic down can be a great way to save on energy costs.
  • Get the most of your Montgomery and Bucks County home’s attic insulation by installing rafter vents before covering the entire floor of the attic with the insulation out to the eaves.
  • Make sure to never cover soffit vents with insulation.
