hi guys
My builder has quoted a flat roof, and based on how he has described how he will build it, looks like he is aiming to build a cold flat roof and put insulation between the joists.
Looking at recommendations, cold flat roofs are no longer recommended for new constructions due to condensation risk.
Unfortunately as it’s going to be a permitted development, I dont have the luxury of roof height for an extra 100mm above the joists.
If we do go with the cold roof route, I plan on asking the builder how he anticipates venting it to prevent condensation. Is there anything else I need to check with him? Interestingly he’s building my roof the same as others he’s built, thus I assume he builds all his roofs as cold roofs.
