Roof Insulation Suppliers in Swansea
Welcome to Roofbase Swansea, your local specialist for high-quality PVCu roofline products. A building’s roofline is its first line of defence against the elements and a key factor in its kerb appeal.
From our branch in Llansamlet, we supply durable, low-maintenance fascia, soffit, and guttering systems to tradespeople and homeowners throughout the Swansea Bay area.

Our Specialist Roofline Range
Our Specialist Roofline Range includes everything from robust replacement fascia boards to versatile hollow soffit solutions, ensuring a durable and maintenance-free finish for your home. We also stock complete square gutter and downpipe systems alongside traditional round rainwater options to provide high-capacity drainage tailored to any Swindon property.
Fascia Boards: Strength and Style
The fascia is the forward-facing board that supports your guttering and the bottom row of roof tiles. We offer two primary solutions depending on the condition of your existing timbers:
-
Replacement Fascia Board: Ideal for new builds or renovation projects where the original timber is being removed. These thick, robust boards are fixed directly to the roof rafters, providing a long-lasting, structural finish that never needs painting.
-
Capping Fascia: If your existing timber fascias are structurally sound and free from rot, our capping fascia (or "cappit" boards) can be installed directly over them. This is a cost-effective way to refresh your roofline with a clean, uPVC finish.


Soffit Boards: Protection and Ventilation
Soffits bridge the gap between the fascia board and the wall of your house. They keep the underside of your roof rafters dry and prevent pests from entering your loft.
-
Solid Soffit Board: Provides a clean, flat finish to the underside of your eaves. These are often used in conjunction with over-fascia vents to ensure your roof stays "breathable."
-
Hollow Soffit: A lightweight and economical alternative. Hollow soffit features a "tongue and groove" appearance, making it easy to install over wider spans while maintaining a modern, linear aesthetic.
Rainwater Systems: Effective Drainage
Properly functioning gutters and downpipes are essential for directing water away from your foundations. We stock a variety of profiles to suit any architectural style:
Modern Square Systems
Our square gutter and downpipe range is a popular choice for contemporary homes. With a high flow capacity and sharp, angular lines, it offers a bold look that complements modern window frames and doors.
Traditional Round Systems
For a classic appearance, we supply round rainwater and downpipe systems. This timeless circular profile is easy to maintain and suits almost any property type, from Victorian terraces to suburban semi-detached homes.
