Aluminium Soaker 100mm x 150mm x 50mm

BPC Building Products Aluminium Soaker 100mm x 150mm x 50mm is a pre-formed, lightweight roofing flashing designed to create a watertight seal at the abutment of a pitched roof and an existing wall. Manufactured from 0.5mm soft aluminium, it offers a durable, cost-effective alternative to traditional lead soakers — without the weight, theft risk, or handling difficulties associated with lead. Suitable for both trade contractors and DIY installers working on new-build and refurbishment projects.

Why Choose This Product

Aluminium soakers from BPC Building Products are a proven, trade-trusted solution across the UK roofing industry. Aluminium will not warp, crack, or discolour over time, and — unlike lead — it carries no scrap value, significantly reducing the risk of theft on site. The pre-formed profile saves installation time, and the lightweight construction makes handling on the roof straightforward. An economical choice for roofers, builders, and competent DIYers seeking a reliable lead alternative.
