If I have an EWI property, can I fit verge trims to the top of the system and put the changing of the trim in the medium-term plan when the roof is reroofed in say, 5 years’ time? I’m of the opinion that as it’s part of the measure being installed then this wouldn’t be allowed as it’s not a measure on its own but part of the system being installed (and PAS 2030 – 2019 states not to use verge trims) but I’m getting different responses from other Coordinators, Designers and Installers?
