The area covered by soffits is not exposed to the weather and so wood is often used to make soffits. However, wood will take in some of the moisture in the air, and over time will warp and distort. Replacing timber fascias and soffits with UPVC is a common job as the UPVC is much easier to maintain as you will only need to wipe it down, instead of sanding back and painting the timber boards.
Here are a few separate jobs showing facias, soffits and guttering in different aspects.
