    Hi everyone,

    I've been going around in circles looking at flat roofing options, from economical EPDM £6k to Single Ply PVC £22k, and struggling to make a decision as i know it is an important one. I am concerned with EPDM not lasting due to the glued seams and shrinkage which seems to be the most common complaints. I found a product that a local installer uses called Resitrix, which seems to eliminate my EPDM concerns as it is heat weldable and much thicker than other membranes at 3.2mm. I was hoping to get some insight from people who have installed flat roofs and thoughts on different products.

    Here is a link to resitrix (any info from people who have used it would be really helpful).

    I have a couple of EPDM flat roofs. My understanding is that EPDM will last longer than PVC providing it is installed properly, so the key is finding competent installers. Try and avoid seams as much as possible; do use a thick membrane. I think mine has a fleece backing.
