Fascia installation is a vital aspect of proper roof construction. The fascia is found underneath the roof line just behind the gutters. It extends around the entire building. Wood is the most commonly used material for fascia although plastic and aluminum are also used. The fascia helps to protect your home from the elements. Fascia also prevents entry of birds, small animals and debris into your home. Proper installation of roofing fascia helps to complete the appearance of your home. Follow the guide below for tips on wood fascia installation.

Step 1 – Measurements

Take measurements along the roofline to find out the exact sizes of boards you need to cut out for your fascia. Mitered joints require some allowance of 1 to 2 inches. This will give you more leeway as you shape the board ends to meet at corners. Use a sliding T-bevel tool to take accurate measurements of angles. The gutter lengths can give you a rough estimate for the quantity of fascia you need to purchase.

Step 2 – Cutting

Purchase the required amount of pressure treated timber from a lumber yard. It helps if you cut the boards several days before placement. This gives the wood a good opportunity to dry properly before it is installed on the house. It also enables you to work more quickly and efficiently. Cut the timber to correspond to the measurements you took.

Step 3 – Lay out the Fascia

It is best to place the fascia in the order you took measurements. This will make installation easier. Begin from one corner of your house. Lay out the fascia on the ground all round until you get back to the initial point of placement.

Step 4 - Installation

It helps if you have a couple of helpers to support you in the project. Somebody on the ground can pass the fascia boards to another helper on a ladder next you. You can then receive the fascia and install. The helper on a ladder next to you will also help you support the fascia as you install. This allows you to use both your hands to drive in nails and speeds up work. Nail the fascia boards onto the rafter ends. Drive nails along the top and bottom edges of each piece of fascia.

Step 5 – Seams and Corners

These require to be tightly sealed to make them watertight. Loose seams and corners will easily allow water to infiltrate your house. Be sure to place the fascia boards tightly together for a secure fit. Some fascia boards with angled ends may be slightly bigger than available space. Sand down the edges for a proper fit. Seal the seams and corners with caulk.

Step 6 – Apply Putty

Once you’ve installed all the fascia boards, place some wood putty on each of the screw holes. This helps to conceal the screws and also makes it easier to paint over.

Step 7 – Painting

Apply 2 coats of primer on the newly installed fascia. Allow the first coat to dry completely before you apply the second coat. Paint your fascia so that it blends well with the color scheme of your house.
