ROOFLINE
Fascias, soffits and associated roofline products are essential components for any property. Exposed to the elements, they play a crucial role in protecting the roof space and rafters of your home. They may go unnoticed most of the time, but old, rotten or discoloured timber fascias and soffits can spoil the look of your property and cause expensive damage to your roof rafters.
Roofline components need to be durable, weather-resistant, attractive and – due to their difficult-to-access location – low maintenance. PVC-U roofline products meet and exceed all of these requirements. you need exactly when you need them – and at great-value prices.
Complete PVC-U roofline systems
We offer everything you need for a complete, high-performance roofline system, manufactured to the highest quality standards. From fascias, soffits and guttering to dry verge, over-fascia ventilation and all the essential trims and accessories – we can install a roofline system that will really enhance your home.
Colour-match and quality guaranteed
All our roofline systems are supplied by the same manufacturer – Eurocell – which means all colours are exactly matched across the product range. That means our whites are the same white across all products and our woodgrain finishes are all perfectly matched. Our roofline products also carry guarantees of up to 20 years against discolouration, warping and cracking.
Local supply for rapid response

Aesthetic appeal

Why choose PVC-U roofline?
