Fascia cap helps hold the soffit in place. The lip of the fascia is installed over the edge of the soffit. Fascia helps provide a weather barrier for the roof truss and is easiest to install with two people working on it. While soffit is generally installed before fascia, it is possible to install fascia first with an installation process that follows the same basic procedures.

  1. 1

    Measure the area of the house where the fascia will be installed. Run a tape measure along the base of the house and around each side where the fascia will be located. Add up all of the measurements and divide by 12 for the number of pieces of fascia necessary for installation. Fascia generally comes in 12-foot lengths.

  2. 2

    Position and climb up a ladder at any end of the house. Line up the first piece of fascia and run it across the house along the fascia board. Turn it so the lip is underneath the eave of the house. The fascia board is attached to the rafters on the front of the house just underneath the roof.

  3. 3

    Hammer the fascia in place with aluminium roofing nails. Insert a nail at the top of the fascia while your helper holds the fascia firmly in place. Move 6 inches down the fascia and hammer in a nail at the bottom. Move down 6 inches and insert a nail at the bottom.

  4. 4

    Insert a nail every 6 inches in the first piece of fascia, rotating from top to bottom. Overlap the second piece of fascia by 2 inches over the first and install it in the same manner. Continue down the first side of the house until you reach the end.

  5. 5

    Measure and mark the final piece of fascia and cut it to size with tin snips, if necessary. Install the remaining fascia on the rest of the house in the same way the first side was installed.
