Lead cement is commonly used in conjunction with timberwork to secure the ridges, hips and other structural elements of a thatched roof. It provides a weatherproof seal, prevents water ingress and enhances the overall durability of the roof’s framework.

The longevity of lead cement can vary depending on factors such as exposure to weathering, temperature fluctuations and the quality of the installation. With proper maintenance and periodic inspections, lead cement can remain intact for several decades before requiring replacement or refurbishment.

Timberwork serves as the underlying framework that supports the weight of the thatch and provides structural integrity to the roof. Properly constructed timberwork ensures a stable base for the thatch material, enhances ventilation within the roof structure and facilitates drainage to prevent water accumulation and decay.
