Flashing Kits

Conservation Rooflight installed with a flashing kit

To truly protect our nation’s heritage buildings, the details around the installation are just as important as the rooflight itself. This may mean, it may be more appropriate to use lead soakers around the jambs of the rooflight for absolutely authenticity.

In situations where this level of detail is not essential, our flashing kit options will provide you with everything you need for a successful installation. Where appropriate, code 4 lead is supplied for the cill flashing and soakers.
The head flashing is a lead-free waterproof flashing material. Each of our three available options have been tailored through our years of experience in achieving the optimum installation process no matter the site circumstances.
