Fascia board is attached to your house behind the gutters. It is located just underneath the roof and installs directly onto the joists. Fascia board will vary in size, but is often made out of a 1-by-8 piece of lumber. Similar to installing any other type of board, the fascia will need to be cut to size to fit properly. Installing fascia is not different from installing any other type of board and it can be completed by any homeowner.
Climb up a ladder and measure the width from the eave of the roof to the bottom of the joist. This is the area where the fascia will be installed. Record the measurement. Transfer that measurement onto a piece of fascia board and mark with a pencil the proper cut location.
Set the fascia board on a flat and steady surface. Line up the mark on the board with the blade of the circular saw. Turn on the saw and align the blade guide along the mark. Cut straight along the line mark down the fascia board and rip it to the proper width.
Line up the fascia board at the first side of the house and hold it in place. Insert two exterior wood screws with a power drill into each joist. Drill one screw through the top of the fascia board and into the joist and the other through the bottom of the fascia board and into the joist.
Move down to the next joist and install two more screws through the fascia board and into the joist. Continue down the first piece of fascia in the same manner. Cut and install the second piece of fascia just like the first and move down each side of the house until all the fascia is installed. Cut the boards to size for both the width and to fit at the end of each side of the house.
Be careful when working on a ladder. Make sure it is on stable ground when in use. Always wear safety goggles when working with a circular saw. This will protect your eyes from flying pieces of debris and wood.
