Is a roof pitch for a glass aisle 2 percent realistic?
My wife and I are currently building a house consisting of a main house and an outbuilding.
The two elements are to be connected by a glass walkway (= 3-sided glass element: 2 glass walls + 1 glass roof).
Now the window company says they can build this fancy glass transition with a flat roof with a minimum slope of 10 degrees and can't make it flatter. The key word: warranty.
Unfortunately, we think it's very ugly. We expected the roof to be very flat. Our architect says the slope should be 2 degrees.
But now the glass roof has to be about half a meter higher in the center than the outside. So it looks more like a gable roof than a flat roof.
Can anyone tell me if this is realistic at 2 percent and what manufacturers are there for this?
Answers
Usually a 2 percent slope is sufficient for roof drainage.
Caution. 2 percent ≠ 2 degrees.
What exactly is the glass manufacturer's concern? (I would take static, rain loads only). What would it be: bulletproof glass, plexiglass?
I would not do a "gable roof" but a "single slope roof", the height of the attic would already give the slope, and 10° would not practically interfere with it (if necessary, a slope is done, with the main view direction).
