Huge hail storm - Repair / replace an aluminum roof

That may be a problem since Monaco stopped using that method of roof construction in 2004 and then Monaco was bought out by Navistar in 2009 and then sold to Allied Specialty Vehicles in 2013. Flat aluminum sheets are available from any Aluminum supply company but getting it bent the way Monaco used it, over a decade ago, will probably not be something that an RV shop will be able to tackle.
