Before beginning installation, ensure that the work area is safe and that you are wearing the appropriate protective gear. Clean the roof surface thoroughly and ensure it is free from debris. Carefully position the lead slate around the pipe penetration, making sure it aligns accurately with the pre-cut or pre-drilled opening. For a secure, weatherproof seal, follow the manufacturer’s guidelines closely when applying a compatible roof sealant. Allow adequate curing time as recommended to achieve optimal adhesion and seal integrity. Always double-check that the slate is fully supported and that the upstand is correctly orientated to maximise its protective benefits.
