What Are Soffit and Fascia? What’s the Difference

What Are Soffit and Fascia? What’s the Difference

Our home’s external design comprises far more than just the roof and siding. A number of small finishing elements contribute to the style, appearance, and functionality of our exterior design. However, we tend to overlook little details.

Soffit and fascia are part of the roofing system. Since these two are installed together along the roofline, we often assume that they are both the same. However, they are not the same and serve different purposes in the roofing system. 

What Is Soffit?

Soffit Difference

The siding material that covers the underside of your roof’s overhang is known as a soffit. It resembles the shape of the box and is installed along the underside of the roof rafters. 

The soffit is rarely visible from the street because it is on the underside of your roof. As you go closer to the house, it becomes more visible.

The soffit material you select should be suitable for the climate where you live in. It usually has a horizontal shape and is made up of a variety of materials. Some of the common types of soffits available are:

  •  Aluminum
  • Wooden
  • Steel
  • Vinyl
  • Fiber Cement
  • PVC

Benefits of Soffit

  • It has microscopic openings that allow air to flow in and out of your roof, allowing for better attic ventilation.
  • It contributes to making roof sealing strong. In addition, it protects the interior of your home against mold and damage.
  • It will give the roof a nice appearance and add value to the exterior design.
  • Prevents bugs, insects, and other unwanted things out of the attic
  • Prevents water accumulation on the roof. 

What Is Fascia?

Fascia or fascia board is the thin flat piece of trim that is fixed to the edge of the rafters. The fascia is the part or portion of the siding that sits just above the soffit. It’s a board that runs along the roof’s edge.

Fascia is the last line of defense against the weather for your roof line and rafters. Because the gutters are attached to the fascia, they are crucial to the roof’s drainage system. It prevents rain, snow, and wind from going underneath your roof. They essentially act as a roof sealant. They also give a fine and finished look to the roof.

They’re available in a variety of colors, so you can choose the one that best matches your home’s exterior colors. Fascia boards are commonly constructed of woods but there are variety of other fascia and they are

  • Woods
  • Plastics
  • Aluminum
  • Vinyl
  • Composite
  • PVC
  • UPVC

Benefits of Fascia

  • It shields the hose from strong winds and rain.
  • Prevents moisture build-up in the home.
  • It provides better protection to the house. 
  • It safeguards the rafters.
  • It helps in the proper flow of rainwater from the roof to the ground by supporting the gutter system and shingles. 
  • Gives a fine and aesthetics look to the frontage of the house

Cost of Soffit and Fascia 

Vinyl or composite are commonly used to make soffit and fascia as they are easy to maintain and endure longer. Vinyl soffits and fascia come in a variety of styles and colors so you can choose the one that best complements the architecture and design of your home. They are also less expensive compared to others.

The exact price of soffit and fascia depends upon the material and style of the house. However, the price can range from

  • Soffit can cost anything from $20 to $30 per linear foot.
  • Fascia ranges in price from $15 to $25 per linear foot.

How to Install Soffit and Fascia

Soffit and fascia are both simple to install.


  1. Secure soffit to the roof rafters using nails. 
  2. Put the thin vinyl soffit loosely with nails as a track
  3. Trim parts such as F or J channels can be used to construct a track
  4.  Now slid soffit is slid into the channels and lightly fastened to the rafters. 
  5. Overlap the pieces of soffit or trim to hide the nails


Fascia is either nailed or screwed directly into the board in the roof. Unlike soffit, this might be a little hard to install on your own. Hiring the best installer is the best option here. 

Signs to Remove Soffit and Fascia

When it comes to roofing or siding, the most important thing to remember is to replace any damaged portions as soon as possible. Your small ignorance can cause some severe damage to the house. Sings when you need to remove your soffit and fascia are

  • Your roof has rotted wood.
  • Any leakage from an attic or any exterior part of the house.
  • Unusual dripping water that drains down the house rather than into the gutters
  • If fascia has become rusty or has an inconsistent color.
  • If there is a hole in the soffit or fascia and insects like bees, hornets, and waps have started to enter the house. 
  • Cracks
  • Soffit pieces dangling
