Hi All, I recently had an exposed fastener 26 gauge acrylic coated galvalume roof installed onto my house. The roof is about 6 months old. Then we had baseball sized hail one night and the roof looks like it got hit all over with sledge hammers. The roof was installed over 30lb felt directly on decking after a complete tear off of old roofing material. This roof does not look very nice, and the ribs are flattened in areas and the edges bent, but it is not leaking. Everyone else in the neighborhood has a blue roof. My insurance has "totaled" my roof and is paying for another roof. I had a thought. If the existing roof does not leak and there is no rust and no other roof underneath it and I know the decking is good, and it is very reflective since it is un-aged galvalume, would it be a good idea to select a roof that could be installed on purlons and put that roof on top of the "old" new roof? Would standing seam be better for this purpose? I am wondering if this would make sense from an energy efficiency perspective and also be less expensive to install. What do you think?

This could be an option. You might want to look into a product called Roofhugger and you also should you wnat to try this need to work closely with the manufacturer of the new roof. This double roof could help increase energy efficiency. Sorry about the storm you had.

I am not a huge fan of people putting metal over asphalt because I think it is penny-wise and pound-foolish (i.e. I don't like the thermal mass of asphalt, the deterioration, inability to access and inspect the sheathing, etc), however, this is certainly a different case. Going metal over metal is a great feature and with a system like the roof hugger or other purlin type fastening, that is going to be a great roof. +1 to Todd's comments about the storm. That is terrible. I have seen video of stuff like that and the power of nature is staggering.
