Fascia boards are mainly horizontal boards that focus on supporting and covering the exposed roof trusses. These boards also provide protection to your home.

You may not have fascia boards installed on your roof. Hence, you might wonder about how to attach fascia board to roof trusses. Fascia boards are generally constructed of materials like wood, vinyl, UPVC, and aluminum.

Attaching fascia boards to roof trusses is not as straightforward as you might think. However, it is not impossible to do it by yourself.

Let us walk you through the procedure step by step.

How To Attach Fascia Board to Roof Trusses 

Attaching a fascia board to roof trusses is a rather complicated task. Hence, you need to prepare yourself thoroughly before you start working. Additionally,  you will need some tools and materials for this purpose.

Necessary Tools and Materials

  • Pencil
  • Miter saw
  • Nails
  • Hammer
  • 1-inch thick pieces of Lumber
  • Ladder
  • Painter’s Caulk
  • Measuring Tape
  • Body Filler Putty

Step by Step Procedure

Step 1

You should start by inspecting whether you have any fascia boards installed previously on your roof trusses or not.

In case there are old fascia boards, you have to remove them. While you are at it, also remove the nails that seem to be sticking out.

Step 2

In this step, you should start placing the fascia board. Begin at the roof corner, then lift a board into the right place. After lifting the board up, tightly hold its top edge. Make sure to hold it against the foot of the roof deck.

Step 3

Find the place on the board which aligns with the center of the joist closest to it.

After that, mark that place. Furthermore, cut a straight line at the mark using a pencil and a measuring tape.

Step 4

After you’ve drawn the straight line,  take a miter saw. You should set it up cautiously on a flat surface to prevent any wobbling.

Then, you should cut the fascia board at the marked place using the miter saw.

Step 5

In this step, you have to position the fascia board in the right place. Place the board against roof trusses. After proper placement, drive in some nails at the ends of the fascia board. This should keep the board in its place.

Step 6

You have to place the next board in the place where the end of the first board meets the joist.  

Follow the previous steps for this board also. Subsequently, all the remaining fascia boards should be installed in the same manner as the first one.

Step 7

You should check whether there are any holes or gaps. If you find any, seal them with body filler putty or painter’s caulk. Sealing the gaps and holes will prevent moisture from getting inside.
