Metal Composite Roofing?

Question:Has anyone had a shake or asphalt roof and upgraded to a metal composite roof (gerard shake, granite ridge)?

Expeirenced any cons of rain amplified, retained heat in the house, and etc?

Today, I received a bid on an asphalt roof and they were saying to stay away from metal composite material, so I would like to hear some feedback.

Answers:
That is what you might expect them to say. I do not know about metal composite but we install standard metal panel roofs all the time that will far outlast any shake or comp shingle roof.
