When you’re up on a roof, you don’t want kit that slows you down or lets you down. The TRO Breathable Membrane is built for graft — a 3-layer polypropylene composite that’s tough as nails, resistant to tears, and fully approved for peace of mind.

It’s been designed to resist water, wind-driven rain, snow and dust while still allowing vapour to escape, keeping the roof space dry and reducing condensation risks. It works in both warm non-ventilated and cold ventilated roof systems, so you’ve got flexibility whatever the job.

I used this very roll on a big slate re-roof in Leeds at the Coach House. We had weeks of mixed weather — sunshine one day, sideways rain the next. The TRO Breathable Membrane held up perfectly as temporary waterproofing until the tiles were on. The lads loved working with it — easy to cut, lightweight to lug up ladders, and no issues with tearing. That job taught me this: once you’ve used TRO, you don’t want to go back to cheap membranes.
