The Swift Foundations Watershed Roofing Kit consists of corrugated roofing tiles, each one made from bituminous material 3mm thick and formed into the classic corrugated shape of a series of ridges and valleys. With tiles supplied already cut to size, installation is rapid since there is no measuring or cutting to do as there is with roofing felt. The tiles easily overlap each other both lengthways and widthways creating a simple but very effective watertight seal. The 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. Each kit comes complete with everything you need to re-roof your building including roof tiles, ridge tiles, timber battens, screws, screw caps and instructions. Suitable for use on pent or apex roofs with a pitch of 10 degrees or greater on sheds, summerhouses, workshops, garages, playhouses, log cabins, lodges, bike stores, shelters, beach huts, logs stores etc. Size: 5 x 7ft.
