Yes, felt for shed roof can be installed as a top layer, giving sheds a strong, waterproof finish without requiring additional coverings.

Why Choose Our Roofing Felts & Membranes

Sourced from leading UK brands, our products deliver proven reliability in all weather conditions. For professional applications, torch on roofing felt provides a bonded finish for flat and low-pitched roofs, while heavy duty roofing felt offers enhanced durability and tear resistance for exposed locations. Our breathable felt membranes combine water resistance with vapour permeability, reducing condensation risk while maintaining a weatherproof barrier. We also stock specialist tapes, such as double-sided acrylic tape, to support secure installation.

How does heavy duty roofing felt compare with standard grades?
Heavy duty felts are stronger, thicker, and more resistant to tearing, making them ideal for high-exposure areas or projects demanding extra resilience.
