Roof-line Boards - What Are They?

Roof-line boards consist of fascia and soffits that are secured to the roof edge of most properties and often support the tiles around the edge of the roof. They also hold up the guttering at the base of the roof and any cemented tiles to the apex of your home. These boards were traditionally made from timber, but due to rot and the constant need for sanding down and repainting, plastic alternatives are now preferred by many specifiers and home-owners.

Colours and Profiles

The Upvc plastic boards come in a range of sizes, shapes and colours. Some boards even have a wood grain effect finish to mimic real timber. The most popular board is of course plain white. However if you wanted to match the colour of your roof-line to your double glazing window frames you can choose from the following:

  • White either smooth or wood grain effect
  • Mahogany wood grain effect
  • Rosewood wood grain effect
  • Golden Oak wood grain effect

All fascia and soffits are fixed to the roof timbers with stainless steel nails which have a plastic cap which matches the colour of the board.

Should I Cap Over or Replace the Original Timber?

Capping over the original timber is never a recommended method for installing Upvc boards, the existing timbers should be fully removed first. Once they have been taken down the rafter ends can be checked for rot and repaired as required. If you were to cap over the boards you may encounter issues on the boundary between your property and your neighbours. If your roof-line is wider than theirs (because you added an extra board) then the roof-line may look a little odd. 


Most Upvc roof-line manufacturers offer a minimum ten year guarantee with their products and most reputable installers will match this with a guarantee covering the workmanship.


To replace the roof boards the guttering first needs to be removed. There is little point in paying someone to re install old and tired guttering so most installers will recommend replacing the guttering as well. This makes sense because once old guttering has been disturbed it tends to leak once it has been refitted to the roof. You could replace the rubber seals/gaskets to the gutter joints/parts but it's really a waste of money, generally best to replace the gutter along with the boards.
