How to reroof on houses that share the same roof.

01/02/2024

A common issue faced in the Devon and Cornwall region is how to reroof, semi-detached properties with a shared roof, where only a section of the roof is being reroofed. In such instances, it becomes crucial to establish a lead join in the roof when two or more occupants share a roof. This is especially vital for seamless roof maintenance and to facilitate individual re-roofing projects for specific sections of the property.

To accomplish the division on the roof, an artificial join is created. After stripping the slate, a 3×1-inch piece of timber is placed down the roof. The next step involves crafting appropriate lead soakers and flashing down the joint to provide an effective water-tight seal. Subsequently, the slating process continues seamlessly up to this join, ensuring a structurally sound and weather-resistant solution for both sides of the semi-detached property. This approach not only addresses the practicalities of shared roofs but also ensures that maintenance and renovations can be carried out efficiently without impacting the property.
