Soffit and Fascia Installation for a Safe and Dry Home

When looking up at your home, you’ll notice how the roof overhangs from the wall of the house. This part of your home involves the underside of the roof line as well as the exposed roof rafters. If this area is not protected, moisture can penetrate the home to allow water damage and mold to form.

Small animals such as birds, bats and other creatures will also use this area to try to enter your home to find a safe place to build nests. Lastly, this roof area should provide adequate ventilation and air circulation to the attic to help prolong the life of your roof. A way to protect this important part of the roofing system is to install and repair the soffit and fascia.

What is Soffit and Fascia?

Soffit and fascia can be confused with each other. Simply put, soffit allows for attic ventilation as it consists of metal panels with vents. The soffit is placed along the roof line’s underside. The fascia is like trimming for your roof that protects the exposed rafters while preventing rain and creatures from entering.

Before Soffit and Fascia Installation

Inspect the roof to look for loose shingles, rotten boards or obstructions. Always repair the roof instead of covering it up as the existing minor damage can lead to worse problems. Now is also the time to measure the square footage of the area that will receive the soffits and fascia. Soffit comes in sizes of 12 foot panels that can be 12-inches to 16-inches wide as you’ll want to buy extra for overlaps.

You’ll place in receiving channels, called F-channels and J-channels, every 12-inches along the wall for. Make sure to leave at least a 1/4-inch gap between the channels to allow expansion along the walls. Cut the soffit panels based on the measurements of the wall to the fascia while subtracting 1/2-inch from the measurements to allow for panel movement.

Nail in the soffits so that they form a 90-degree angle to the wall. Once in the slots, the panels should meet. The tongue and grooves on the underside of the panel will line up to the panel beside it.

Install Fascia

To know how to install fascia measure and cut based on the area where it will be installed. Place the top edge of the fascia underneath the drip edge as the bent bottom lip will tuck underneath the installed soffit. You want to start the work on the eaves at the back of the house and at the bottom of the rakes to hide the gaps when overlapping. Every 24-inches, you’ll install nails or drill in screws carefully so as not to buckle the metal.

Make sure to overlap every piece of fascia by 6 inches. When attaching the fascia, never place in a nail that is 3-inches from the end of the fascia piece. It can cause the fascia to pull away and create a gap.

Placing Fascia Along Corners and Peaks

Always make sure the first piece of fascia is wrapped around the corners so that the second piece overlaps to give a nice, clean look. The second fascia piece should end flush along the corner. When placing fascia along the peaks, notch the bottom lip of the first piece at the place where it hits the soffit. Then place on the second fascia piece as it will overlap to form a plumb cut.

What is the difference between soffit and fascia?

Think of a soffit as the underside of the arching points of your roofing system. The fascia is what is used to create a barrier between the edge of the roof and the outside.

What is the purpose of installing soffit and fascia?

One of the commonest reasons why soffit and fascia are installed on roofs to protect the roofing system from damage. This may be anything from mildew growth that may cause leaks to rust and bad weather.

Is it okay to have a roof without soffit and fascia?

Soffit and fascia are not the components to ignore when installing your roofing system. While you may opt to leave them out due to cost-effectiveness, it is good to think about installing them in future roofing repairs and maintenance.
