SB: Help with metal roof installation

["Rey Arbolay" <TXH2344@mynra.com>]

I have ordered all the materials to install a steel roof on my 
house with the eventual purpose of collecting rain water. I will 
not remove the current single layer of asphalt shingles on the 
roof. I have seen it installed two ways. The first and most common 
is by running latice strips every 3 feet paralel to the roof line 
and attaching the panels to this strips. The second way is by 
covering the existing shingles with tar paper and attacing the 
metal sheets directly to the decing thru the tar paper and 
shingles. Question, what is the superior method. I live in central 
texas and extreme heat is a concern, but believe that attaching 
the panels directly to the decking might reduce sound transmition 
problems (when it rains) and provide for a more wind proof 
installation. On the other hand, I am afraid that installing 
directly might cause buckling problems under extreme heat 
conditions encountered here in central Texas.
Opinions, suggestions, web links, help?
