My understanding is that we can't use Verge trim AT ALL. We do mainly EWI and going back over our work 60% of it has needed Verge trim. As a coordinator what do we do with these houses. Reject them all? The customer is certainly not going to pay for the roof extension. We've only ever had 2 customers do roof work to accommodate the EWI and that's because they were having a new roof anyway. What about if we can evidence it’s been correctly installed or we can mitigate the risk of water Ingress with lead flashing or a secondary barrier. As a coordinator how should we deal with this issue?
