Our garden shed has sprung several more leaks through the felt roofing. This has last less than a year. Is it worth going for twinwall poly sheets? It's a 8 foot by 6 foot sloping roof. Looking for something inexpensive, that'll last longer than a year. Thanks gang
Mine too, but I made sure it was a green- mineralised polyester-fibre-based roofing felt, plus I used roofing felt adhesive on the overlaps. It's going to outlast me.
