Hyperbolic Paraboloid Parabolic Roof

A hyperbolic paraboloid sometimes referred to as h p is a doubly curved surface that resembles the shape of a saddle that is it has a convex form along one axis and a concave form on along the other.

I m not sure how you have modeled this. A hyperbolic paraboloid roof is a configuration which has esthetic structural and economic advantages for many purposes as for example inexpensive attractive large area structures free of. The hyperbolic paraboloid is a doubly ruled surface so it may be used to construct a saddle roof from straight beams. But this roof is lowered into a fine tip and a shallow saddle.

The two roof faces do in fact appear to be hyperbolic paraboloids. This is because the pitch at the beginning of the roof let s say small end and the end of the roof are not the same or at least it appears that way from your elevation.
