1) What’s the difference between fascia boards, soffit boards and capping boards?
Fascia boards fix to the roof edge to support the gutter line. Soffit boards finish the underside of the eaves. Capping boards fit over existing fascia to cover and protect it without a full replacement.
2) When should I use a capping board instead of replacing the fascia?
Capping is a good option when the existing fascia is sound and straight, but looks tired or needs a new finish. If the underlying timber is damaged or uneven, full replacement is usually the better choice.
3) What trims do I need to finish a roofline installation neatly?
Most jobs use matching trims for edges, joints and corners, plus the right fixings for the board type. Using the correct finishing profiles gives cleaner lines and helps the roofline look consistent all the way around.
