This may not be the right forum for this question but here goes. I purchased a used camper and after two trips found out the roof wood was rotted out. Bummer. However, I have succesfully removed the roof and am about to start the rebuilding process. The manufacturer glued the sheet metal to the wood. The wood was so rotten it the old glue isn’t a factor. However, for strength I would like to a glue the replacement wood to the old sheet metal (it is in good condition). Any suggestions for a glue? It need to have a at least a 30 minute working time.
Also, if you ever think about buying a used (or new on the lot) camper. Take a screwdrive with you and ask if you can back out a couple of screws. If the screws are rusted, run away from the deal. I wish someone would have told me this. The roof didn’t leak into the camper itself, it just let in enough water to saturate the wood.

If the glue will not be subjected to direct weather I would think the correct type of construction adhesive will do the job .

Polyurethane glues, like Gorilla Glue, will stick metal to wood extremely well. If fit-up is a problem, then a polyurethane construction adhesive might be the best bet.
One of the construction adhesives is probably your best bet.
If you have some way to keep clamping pressure on the joints, then a polyurethane glue, like Gorilla Glue, would work well. But, if you can't maintain the pressure on the joint the poly glues will foam, resulting in a drastic reduction in the joint strength.
One method that might work with the poly glues would be to get some long sections of t-track and drill through the sheet metal, and into the wood substructure to mount them on the roof. This would have the bonus effect of providing convenient tie downs. You can get 8-ft pieces at:

an alternate track system is from 80-20, they have an ebay store that sells off cuts, and over runs. This would work well: http://cgi.ebay.com/80-20-T-Slot-Aluminum-Extrusion-15-S-1534-L-x-96-5-N_W0QQitemZ220356708629QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item334e488915
Another option would be an acrylic adhesive tape. Not sure of a retail source on it though.
I came across this website http://www.thistothat.com/ a while ago that gives advise on how to glue lots of different materials.
