    Do I need lead flashing on my roof?


    Hello, I have no lead flashing on my artificial slate roof, but have been told there are lead soakers. My local roofer says lead flashing isn’t a requirement for this roof type. Does anyone know if I should have lead flashing on my roof? I have some concern that some leaks on a ceiling-adjacent wall could be related to this, or perhaps the soakers aren’t effective enough. Any info would be appreciated – thanks Gordon

    "Generally, lead flashing would be the recommended choice, but in either case, lead flashing or lead soakers need to be completely sealed. Without correct sealing this can cause issues like damp, leaks or possibly the likes of your wall leak. (Sealing can be done slightly cheaper with cement, but this is less recommended as cement will not last as long.) It is very important to have the roof flashing/soakers fitted correctly to be watertight.
    I would recommend seeking a roofer, as soon as possible, to fully survey your roofing and make sure that the soakers or flashing is sealed correctly. Additionally, for them to test that your wall-based issue is not related. The longer you wait, the more issues that can be caused if there are leaks or ineffective sealing."

    "No you don't always need lead but I always use it for this exact reason, the soakers are OK but can sometimes move or slide down allowing water in."

    "Most roofs do have a lead flashing connected to the wall ground into the brickwork but some slate roofs are okay with lead speakers so if it's not leaking its probably ok if its peace off mind then yes put a lead flashing in it won't hurt thanks hope that's okay"

    "Hi there, yes you do need lead flashing on any type of roof i.e chimneys is a must. Years ago, they used cement fillet and lead soakers under the cement fillet. But I would advise you, as a roofer that a lead flashing is required or water will get behind."

    "Lead flashing is essential where slates/tiles either meet a wall/chimney to ensure a water tight roof. Soakers will do their job but the lead work is needed. Also makes it look complete, and professional."

    "If you have soakers there must be some source of flashing otherwise water will just run straight down the back of the soaker."
