Just a few nodes to create this Roof?
The one with the fewest (custom) Nodes/Lines of Designscript wins and receives a Japanese bow…

I’m not convinced the edge profile is a pure sinusoidal - there appears to be a slight dip where the tangent would be 45 / 135 degrees

Note there is an overhang at the drip, where the plan view of the roof would have a bit of a “speed bump” rather than a flat edge.
Also I personally feel the amplitude might be a little bit off, but I guess that’s a moot point as proportions are variables after all.
You may also want to add an intermediate ‘flat’ to exaggerate the transition point of the waving shape.
p = Point.ByCoordinates (Math.DegreesToRadians((0..(180*8)..10)),(-10..10..#9)<1>,(Math.Sin((-90..(180*8)..10)+(0..90..10)<1>)*(-1.25..1.25..#10))<1>);
GeometryColor.ByGeometryColor(NurbsSurface.ByPoints(Point.ByCoordinates (p.X,(p.Z<-0.6 ? p.Y+(-p.Y*(p.Z)*0.08) : p.Y),p.Z)).Thicken(0.25).Translate(0,0,1.5),Color.ByARGB(255,255,250,200));
This is the reason for the convoluted code

I’ve posted an article that should hopefully explain the process of creating the geometry better than the two lines posted above.

Thanks @Marcel_Rijsmus 
Looking forward to more such exercises that provide me topics to elaborate about
@Vikram_Subbaiah
check all your solutions to all of the challenges i posted in the past.
That’s where inspiration for more explanations sleeps
