What is Roof Felt
Beneath roof tiles, roof felt serves as a crucial secondary defence against rain, snow, and dust, offering essential waterproofing. It effectively captures any moisture that bypasses the tiles, safely channelling it towards the gutter. While traditional roof felt has a proven track record of durability and reliability, contemporary alternatives, such as breather membranes, offer superior performance.
What is a Breather Membrane?
Breather membranes, a modern alternative to roof felt, are designed to be both water-resistant and vapour-permeable. They prevent water from entering the roof while allowing internal moisture and condensation to escape. This ventilation helps prevent mould, rot, and structural damage, thereby preserving the condition of roofing timbers.
