I am building our home in dallas texas. The main house is built out of structural insulated panels (SIPS). However, the covered patio, which is attached to the house, is stick framed. The patio roof cavity is about 3' from the ceiling to the roof and about 12'x20' overall. The roof is a slightly sloped flat roof covered with white TPO. Three side of the patio are open with the forth side, attached to the SIPS wall of the home. I am concerned about siting below an oven during the heat of the summer, however it is in the high nineties as I write this, and it doesn't feel hotter than normal. The architecht is recommending that we vent the roof with intake on one side and outtake at the other end. Is it nessesary and are there any special considerations?
