The old metal roof on my garage is in fairly rough shape, rusty and leaking in spots. I'm planning on replacing it and now I'm faced with some choices. I could go back with the galvanized stuff that's already on it, or the installer has mentioned something about an 'aluminized' metal roof? His take on it is that it does away with the rusting problem.

Does anyone have any experience with this stuff and have any suggestions? Sure would appreciate it.

Steel metal roofing is typically Galvanized (steel witha zinc+aluminum coating) or Galvalume (steel with an aluminum + zinc coating). If you are anywhere near the coast I would go with pure aluminum but it is more expensive. Otherwise galvanized or galvalume will do allright, but there's always the risk of rust at penetrations and cut edges.

If you're buying a system that uses through-fasteners (exposed fasteners) then you aren't really buying a metal roof. You're buyng metal cladding that relies on little neoprene washers for watertightness. When those neoprene washers dry out and rot, it will leak. Go for a concealed-fastener system unless price is more important to you than lasting.

I work for a metal roofing manufacturer and if you are interested in some "seconds" or obsolete color stuff, I could get you a great deal on aluminnum shakes or shingles. PM me if interested.

Sorry for all the pimping but how often do I get a metal roofing thread on ARFCOM?

I have requested some information on the click lock - looks great - I would like to roof my barn with it

is it difficult to work around penetrations like the cuppola, dormers etc.
