What Is Soffit and Fascia on a House?

Soffit on the Underside of a Roof.

What is the purpose of soffit and fascia?

Although often overlooked, soffit and fascia are essential components in your roofing system. Their functions range from ventilation to protecting your roof from small animals. Soffit is a type of siding affixed underneath the eaves. It has small holes in it to allow for circulation, and it exists primarily as a source of attic ventilation. It also adds to the aesthetic appeal of the home. Fascia are the boards on the outside of the home connected to the ends of trusses and rafters as added protection for those components. It protects the edge of the roof and is where gutters are attached.

Is a soffit necessary?

Soffit plays a vital role in your roof’s overall health. In addition to serving as a ventilation source for the attic, soffit also works with the fascia to protect the rafters. Soffit fits underneath the eaves and covers the rafters. Without soffit, the rafters are exposed to the elements, which can lead to several problems including moisture build-up which risks leaks and mold growth. 

When you have properly functioning soffit, your roof’s ventilation will improve. Good ventilation is essential for overall energy efficiency. Your HVAC system also helps improve energy efficiency. Make sure all of your HVAC system is well maintained. If your heating is provided by a boiler and you need boiler repair, that will help with energy efficiency in the winter.

What is the difference between an eave and a soffit?

Eaves are the whole underside of a roof and extend over a building’s external walls. Soffit is siding that is fitted under the eaves to protect the rafters, and serve as a source of attic ventilation. Soffit not only appear on roofs but on the underside of arches, balconies, staircases and other architectural elements.

What causes soffit damage?

Any number of things can cause damage to the soffit. One of the most common problems is roof rot. Because of its location under the eaves, soffit is vulnerable to water damage, which, in turn can cause issues like mold growth and rot. Water damage doesn’t just come from rain. Ice dams force water inward against the soffit, as well. Flaws in the roofs structure like missing shingles or improperly installed flashing can cause the soffit to become damaged as well. Damage to the gutter can damage both the soffit and fascia, and will require soffit and fascia repair. Animals are also a big source of soffit damage. They can chew into the material and work their way into the eave space and nest within those spaces.

Soffit repair or replace

When your soffit is damaged, the decision to repair it or have it replaced altogether will depend on the extent of the damage and the type of material required. When you are repairing or replacing soffit,  you also need to consider the possibility the space underneath it could be damaged as well. If it has begun to rot or separate from the eaves, the eaves or rafters may be damaged as well. 

How to repair fascia and soffit

If you have damage to your soffit or fascia, you may be wondering, How to repair fascia on house or how to repair the soffit on the house? Soffit and fascia repair can be tricky because you’ll have to also consider the roofing material underneath both. Rotting is the most common problem you’ll encounter.

Here are the steps for soffit and fascia repair:

  • You’ll first remove the shingle mold, prying it loose from the fascia.
  • You’ll then remove the rotted fascia, taking care to not damage shingles or flashing. 
  • Next, you’ll remove the damaged soffit.
  • If the rafter underneath is rotted, you’ll need to remove the rafter with a reciprocating saw, and cut a replacement piece using pressure-treated lumber.
  • You’ll then replace the rafter.
  • Following that you’ll attach the soffit. Some materials like plywood may require a sealant applied beforehand to protect the material.
  • The fascia board is then replaced.
  • Finally, the shingle mold is replaced.

How do you replace fascia boards?

When you repair soffit and fascia, the fascia board may be the most difficult part to be replaced. The damage fascia board must be measured out first, so you can ensure the board you replace it with is the right size. Once the board is measured, you’ll remove the guttering around the section of fascia you’re replacing. Before the damaged fascia is removed, the roof needs to be lifted from it. You’ll then mark, cut and remove the damaged fascia board before replacing it with the new piece. You’ll then paint the new board and replace the guttering.
