Project Overview

Fascia board holds your gutters in place and protects the edges of your roof. These areas are exposed to a lot of moisture and over time can start to rot. This video shows you a clever way to remove the old, rotting section and replace it with a brand new piece of timber.

  • Step 1. Measure the existing fascia board and prepare tools

    The simplest way to fix rotten fascia board is to cut out the old section and replace it with a new piece. Start by getting all the tools and materials you need. It’s important to measure up your fascia board first to make sure you get a replacement piece of timber to match.
  • Step 2. Remove the guttering from the fascia board

    Guttering is normally held onto the fascia by metal clips. Use a pair of multigrips to pull these clips back to release the section of guttering. Once the whole section is free, roll it out and place it on the ground. Some sections of guttering can be quite long, so it’s a good idea to get another person to help you.
  • Step 3. Lift the roof off the top of the fascia board

    Use your wrecking bar to pry the nails out of the roofing above the rotten piece of fascia. Then lift up the roofing off the board and place a timber block underneath to prop it up. Make sure you remove any gutter brackets that might be in the way.
  • Step 4. Mark the line where you will cut the fascia board

    Working from the rotten section, find the nearest point where your fascia has been nailed into the roof joist. Draw a line between the nails and the piece you’re planning to remove. This will ensure that the retained fascia is still properly nailed into the roof.
  • Step 5. Cut the fascia board

    Before you cut out your fascia, set your saw blade to the depth of the board. This way you will cut safely through the board without blunting your blade on the wall behind the fascia. Cut up from the bottom of the board.
  • Step 6. Remove the old fascia board and replace it

    Use your wrecking bar to pry the rotten fascia off the building. Once you’ve removed the rotten board, measure up your space for the replacement fascia board. Cut the fascia to length and nail it into place using galvanised nails.
  • Step 7. Paint the new fascia and put the guttering back into place

    Now that the fascia has been replaced, it’s time to prepare the surface for painting. Use your gap filler to tidy up the join between the old and new fascia. Then give the whole fascia a light sand. Next reattach the metal gutter clips, put the guttering back on and it’s ready for painting.
