What Is Soffit and Fascia and How Does It Affect Your Roof?

When it comes to roofing, there are a lot of components to consider.  While Shingles, Underlayment and Flashing may get all the attention, Soffit and Fascia are two important, and often overlooked pieces of the roofing system.  Before we can understand how they affect our roof and homes, we must understand what they are.

Your Soffit is the underside of the exterior, connecting your roof line to your home.  While the Fascia is a finishing edge connected to the trusses and rafters, and horizontal roof line on which the gutters are attached.

The first role for both the soffit and fascia is to protect the attic area from the outside elements.  Birds, Bees, Rodents, and inclement weather can cause a lot of undue damage to your home once inside, and your soffit and fascia act as the first line of defense by sealing off this area.

The second important role of these components is to aid in ventilation.  In West Michigan, we say, “If you don’t like the weather, wait 5 minutes”.  With moisture in the air and in our homes, these sudden temperature swings can cause a great deal of condensation as well as excessive heat build up.  Left without proper ventilation, this can lead to damaged wood decking, mold and mildew growth, and even premature aging of the roof.  Proper ventilation in the soffit and fascia can allow this excess moisture and heat to escape to allow for a more ideal environment for your home.

Proper ventilation will not only aid in the longevity of your roofing system, but can also save you money on your heating and cooling bills.  If you are considering replacing your roof, don’t just “slap a shingle up” and call it a day.  Have a roofing professional assess your entire project, so you can be sure to address all the necessary components and ensure a high quality roof that will last.
