Dear West Wing, Seeseng, swifbuit and the rest of the Sifus,

My BH is near completion 20' x 60' single floor, the roving area is 11' x 8' due to the limited building structure. What is the ideal size or minimum size of the Open Roof hole? The roofing is tilted at 10 degree angle.

Pls advice and thanks in advance.

Regards,

Guswift
