So as im building a flat roof with a rooflight in i know the glass must sit at a 3 degree fall.
My question is, if the roof is aalready falling atleast 3 degrees does the rooflight need to have a additional 3 degrees on the upstand frame, or can my frame sit on the roof flat which would already incorporate the fall.
Hope that makes sense
