I need the last 20 years annual expenditures on roofing in U.S.  New
or replacement or both. The data must come from a consistent source
and must be complete. I am interested in how much these expenditures
fluctuate and how responsive they are to the economy, especially the
replacement market. I am in a huge rush so please don't take this one
unless you can devote yourself.




Please don't take this question unless you can turn it around pretty fast.
