Your customer only thinks he wants a tin roof. What he really wants is a metal roof. You can have a pitch of 1 1/2 to 2 inches. Just enough slope for the water to run. If done correctly,it will not leak. Now however, you do not want to build on a metal roof. Bad deal. Many leaks will result. Now if your customer does want a deck on top of his building and the roof is almost flat, what you want to install is a rubber roof. Very popular, but more expensive. Hope this helps.

Im thinking that Jack is talking about a single ply rubber roof, wich is either fully adhered, or ballasted, either with pavers or with pea gravel. if this is what you are going to do, you would have to install a drain in the roof, (assuming the roof is flat). my best suggestionis to not do this if your not familiar with it, find a local contractor who specializes in flat roofs, because if they are not properly installed the manufacturer will not warrantee them.As for putting a deck on top of it, you can set your supports on top of pavers to prevent them from putting holes in the rubber, jus make sure that your framing, and decking can support the wieght.GOOD LUCK

A rubber roof is a rubber roof. It comes in big long rolls. Like 15 feet x 20 feet. How it works is you take off the old roofing and many will put down new sheeting at least 1/2" plywood over the existing sub roof for a smooth surface. Then you mop on this glue, let it set for about 15 minutes, and rool out the roof. It takes several guys to handle the roofing because of the weight. It is about 3/8 : thick. Kind of like neopreme in texture. Great stuff. This is for roofs that leak. It comes with a full set of instructions and even a kit of you have to join edges.

Well Jack you are close, But EPDM or rubber roofing is not 3/8 inch thick. It comes in 2 thicknesses .045mil and .060mil and usually does not come with a kit or directions. For the type of roof that rickn57 is talking about a fully adheared system would seem to be the best. That system does not require a ballast.
