roofs

Have seen flat roofs and rounded. I would think that rounded would leak less (drain the water better).
Have also seen seamed (on the flat). Do some mfgs use seamless??
Some trailers have rounded fiberglass to nose.
What are your obsevations, experienes, regarding roof styles and materials??
Thanks
