During the rainy months, I blogged about how to protect your roof from the elements. Now that summer is here, it might be a good idea to talk about the best ways to keep your home comfortable and keep your utility bills from skyrocketing.

We all need a roof over our heads, but a roof that does not allow adequate ventilation could do your house and your family more harm than good.

Mr Roofing Home Ventilation Improperly ventilated roofing systems increase the temperature in your home, raise your utility bills, shorten the useful life of your roofing materials, and cause mold to grow in your rafters, which can wreak havoc on your family’s health.

What’s the solution? An attic fan...or, at the very least, a well-ventilated and insulated roof system.

Year-Round Climate Control

There are a couple of warning signs that signal your attic is not insulated properly:
  • In cold winter months, if you notice frost in your attic, it means the moist air is trapped and rotting your roof.
  • In warm summer months, if you notice your asphalt shingles are curling up at the edges or the felt and shingles are buckling at the seams, too much hot air is trapped in your attic.
If you think your attic fan might not be functioning properly, check the vents to make sure they’re not clogged. The fan is strong enough to let small seeds and leaves into the vents. Clearing the debris from soffit vents should help with the quality of the airflow.

It’s All about Insulation and Ventilation

You’ll get a fair amount of passive ventilation through a properly installed ridge and soffit ventilation system. The industry standard is to install one square foot of ventilation per three hundred square feet of attic.

If you aren’t sure what sort of ventilation you have up there, and you feel comfortable climbing up a ladder, go ahead and take a good look around. Or, you can call a professional. We are certified by Owens Corning for insulation installation, and our in-home estimates are always free of charge.
