Roof Timber Suppliers Plymouth
At Roofbase Plymouth, we provide a comprehensive selection of structural and decorative timber tailored specifically for the roofing and construction industries. From major housing developments in Sherford to traditional roof repairs in Plympton, our timber is selected for its strength, durability, and reliability. We understand the demands of the South West climate, which is why we ensure our wood meets the highest industry standards for performance and longevity.

Our Specialist Timber Range
The choice of timber grade and material type is critical for ensuring your roof can handle the necessary loads, including heavy tiles and Wiltshire snowfall.
C24 Graded Carcassing Timber
When strength is non-negotiable, C24 graded carcassing timber is the industry standard for structural roof framing. Higher in quality than the more common C16, C24 is kiln-dried and strength-graded to withstand greater loads over longer spans.
-
Best for: Roof joists, rafters, and floor beams.
-
Key Benefit: Fewer knots and physical imperfections, providing superior stability and less risk of twisting or bowing.


Roof Trusses
For modern developments and extensions, roof trusses offer a highly engineered, prefabricated solution. These triangular frameworks are designed off-site to your exact specifications, allowing for rapid installation and consistent structural performance across the entire roofline.
-
Best for: New builds, large extensions, and complex roof shapes.
-
Key Benefit: Transfers the load of the roof to the external walls, often eliminating the need for internal load-bearing walls and creating open-plan spaces.
OSB (Oriented Strand Board)
As the go-to sheet material for modern roofing, OSB (specifically OSB3) is essential for creating a strong, flat deck for EPDM, GRP, or felt systems. Composed of compressed wood strands and moisture-resistant resins, it provides a stable and cost-effective alternative to traditional plywood.
-
Best for: Flat roof decking and pitched roof sarking.
-
Key Benefit: Engineered for humid conditions, providing excellent dimensional stability and load-bearing capacity.


Roofing Batten
The final step before tiling or slating is the installation of roofing batten. We supply BS 5534 graded battens (typically identifiable by their blue or red treatment), which are pre-graded for strength and safety to ensure they can act as a secure foothold for roofers during installation.
-
Best for: Fixing clay tiles, concrete tiles, and natural slates.
-
Key Benefit: Pressure-treated to protect against fungal attack and wood-boring insects.
