Roof membranes and underlayment

Roof membranes and underlayment creates a vital protective layer beneath roofing tiles or slates. Traditionally known as roofing felt or underlay, modern roofing membranes now provide durability, moisture protection and breathability. Using the correct roof membrane under tiles prevents water ingress, reduces condensation and protects the structure from damage. With options ranging from breathable membranes to reinforced roofing underlay, the right choice ensures long-lasting roof performance.

Historically, roof underlayment involved bitumen-based roofing felt and underlay, laid beneath tiles or slates to shield the timber structure from leaks and damp. Today, roof membranes have evolved significantly, offering enhanced weatherproofing, improved energy efficiency and quicker installation.
