Where a roof meets a wall, chimney, dormer or roof window, a flashing seals the joint. Lead has been used for this for centuries because it can be shaped to fit and lasts well when installed correctly.
Many leaks come from lead that has cracked, slipped, been fitted in lengths that are too long, or had its mortar joint fall out of the brickwork.

Leadwork and flashing: common questions
Why does lead fail?
Common causes are long lengths that crack with thermal movement, loose wedges, perished pointing or physical damage.
Are there alternatives to lead?
Yes, there are lead-alternative flashing products that can be useful where theft is a concern. We'll explain the pros and cons.
Can flashing be repaired with sealant?
Sealant can be a temporary measure, but a correctly fitted and pointed flashing is the lasting fix.
