Fascias are the boards that are fixed to the bottom edge of your roof at the front and rear of your house. Their main role is to: Hold the bottom row of roof tiles in place Provide a solid base on which to fix guttering. Stop the exposed ends of your rafters absorbing water, which can lead to damaging damp and rot.
Soffits are the boards that fit between the fascia and the wall of your home. They’re less visible than fascias (you have stand closer in to your home to get a good look at them) and slightly less exposed to the full force of the weather. They are designed to: Protect rafter feet from rain and moisture Seal the roof space so birds and rodents can’t find their way in and build nests.
