Inquiry (采购产品): roof project Have any seamless metal roofs been retro-fitted to take the place of a asphalt roof on a commercial building? What is the minimum pitch requirements for a seamless roof? I have several building projects in which I am looking for alternative solutions to reduce the cost & extend the life of the current asphalt roofs.
