Can anyone help with suggestions on roofing materials that would be appropriate to finish our roof?
Originally the architect suggested metal sheeting, which I thought was a horrible idea. He told me that Long Khu roofing sheets could also be used and that was what we planned to use but have since been told that given the lack of slope in the roof that we will have problems. The front and back of the roof are almost flat (very slight backward slope), and it has a gradual slope in the middle (perhaps about 10 degrees). I have a picture of the roof framing which I can provide, but don't seem to have rights to post images yet? We have consulted with lots of engineers and roofers, but are getting mixed opinions on what will and will not work. I hate the idea of using metal sheeting, but if we have to resort to that, will it make the house horribly hot? I have 5mm insulation with double sided foil to put in the roof, would that be enough to keep the house cool?
Any help would be greatly appreciated.
