Fascia boards are the caps that are applied to the ends of rafters to create a complete seal for your roof. Installing vinyl fascia boards requires a little more pre-planning than hanging wood, but the resulting cap is more durable and resistant to both weather and decay.

You will also need the assistance of a friend or neighbor.

Choose a Safe Saw Table Location

Before you begin, set up your cutting area in a safe place. Avoid having to move back and forth over the power cords, and set up so that a cut board can go directly from the saw table to the installation without having to be turned around or flipped over. Never situate the work area in or near standing water, or in areas that have a high risk of causing trips or falls.

Verify Your Measurements

Measure the length of each board as you go. Remember a favorite saying among carpenters: "Measure twice, cut once." By verifying the measurements before a cut is made, the entire project will proceed smoother, and there will be less waste materials when the job is complete. If the exact length of a board can not be made for some reason, the rule of thumb is to cut the piece longer than required, and then make additional cuts as needed.

Mark the Board for Screw Placement

On the starting side of the board, drill two holes approximately ¾-inch in from the edge, and 1 inch in from the top and bottom edges.

Take one end of the board and have your helper take the other. Carefully climb the ladders. Place screws in the two holes you have drilled to hold that end in place, and while the helper holds the other end in position, carefully mark the board for the centers of each rafter.

Remove the two screws and return the board to your work table.

Pre-Drill Screw Holes

Drill two holes for each rafter, according the the center marks you made in the previous step. These starter holes will make mounting the fascia boards much easier. The job can be performed without drilling holes in the vinyl, but using them will provide the best overall results.

Cut Joints to Overlap

If you need to have joints in the fascia, be sure that the joining ends are cut with a 45-degree angle so that they will fit together in a tight overlap. Always cut the vinyl so that joints are located on a rafter end (rather than between rafters).

Install the Fascia Board

While holding the vinyl fascia in place, install the screws, one rafter at a time. Do not start in the middle and work outwards, but move in a straight line across the surface as you screw it into place.

Prepare Material as You Progress

Repeat the above steps as needed. Many professionals will pre-cut and pre-drill all of the holes at once, but this is not recommended for novice do-it-yourselfers as it introduces a far greater margin of error.

By cutting and drilling each piece as you go, you will have to make fewer corrections, and the finished product will fit seamlessly together to form a seal along the bottom ends of the rafters.
