This resilient and long-lasting Watershed Roof Kit by Swift Foundations is ideal for those looking for a hard-wearing upgrade or replacement roof for garden buildings. The pieces are easy to manoeuvre and fit into place due to the lightweight design. Watershed Roofing Kits consist of corrugated roofing tiles, each one made from bituminous material 3mm thick. They are formed into the classic corrugated shape of a series of ridges and valleys. The tiles are already cut to size so there is no additional measuring or cutting to do. The Watershed tiles overlap each other both lengthways and widthways creating a simple but very effective watertight seal. Rainwater is channelled down into the valleys of the tiles and then down the slope to the eaves or gutters, keeping the roof of the shed snug and dry. Manufactured in compliance with EN534:1998 Corrugated Bitumen Sheets and ISO14001:2004 Environmental standards. This kit is suitable for covering buildings sized 5 x 5ft.Care InstructionsNo ma
