At BSO we have all you need to complete your roof so it is durable and watertight. Aluminium soakers are easy to install and are a great alternative to Lead. Soakers are cost-effective, non-warping and do not discolour. Lead Slates can be used on both slate and tiled roofs and once fitted will last a lifetime. Lead slates are used to create a watertight seal around a pipe through roofing. We source from industry leading brands Samac and Calder to ensure the hightest quality products.
