Soffits protect your home, bridging the gap between the roofline and your home’s external walls.

Modern, low-maintenance soffits will keep the underside of your roof looking attractive, clean and tidy as well as protecting the underneath of the roof overhang.

Combined with our fascias and guttering, replacement soffits minimise repairs and maintenance saving you money over time. 

Coastline Windows uses hollow, extruded match board with featured ‘V’ grooves.

In most cases, in line with current building regulations, soffit board is provided with a patented ventilation system.

It is important to prevent the soffit board bowing, so to make sure that there is sufficient support we fix new treated timber ‘noggins’ at the necessary intervals as we fix on the new soffits.

To make sure that there is a perfectly straight finish we run a strong line from the first to the last rafter foot. We then cut back to the line, or pack up with PVC to the line as appropriate.

When our expert, highly-qualified installers remove your existing soffits and fascias we will treat all exposed timbers with a good quality wood preservative and also check for any rot or other damage that needs repairing. If it involves any additional materials or labour to put any damage right we will keep you informed at every stage in line with our excellent customer care reputation.

Coastline can also supply new cladding to complete the new look of the outside of your home.
