The installation of T-Pren expansion joints staggered along lengthy runs of leadwork allow for the naturally occurring expansion and contraction that leads to cracking over time. These are a retro-fit item designed specifically for this purpose with minimal disturbance to the surrounding roof covering.
Individual patch repairs to solve pinholes and minor damage will also ensure your lead roof remains watertight for years to come.
