Single ply roofing uses a synthetic membrane with an integral underlay backing which is glued to either the existing roof or to the roof boards on a new build. Hot air is used to weld all seams in the main roof sheet and to add flashing material and trims etc. at the roof edges. 

The single ply material forms an ideal base for a green roof with sedum mats in a water retaining growing medium installed on top of the single ply. 

The single ply membrane is a cost effective material to use for relining a failing metal gutter to extend its life.
