Roof/metal vs compostion

I checked some warranties on the NET.
It depends on the how the warranty is written. Some shingles companies do not allow second layers. Mostly architectural types. My roof is architectural and required removal.

Yeah, Ron, since there are so many kinds of shingles or roofing materials, I've no doubt the warranties are different, too. The only shingles I've personally had experience with are the 3 tab composition shingles and I've done it both ways; i.e., put a layer on over the old ones and strip to bare wood, new felt, and new shingles. Hail damaged lots of roofs in my current neighborhood a year ago last May and most of the houses simply had another layer added, while the mobile homes were stripped and re-done.

Well when my MH was new fleetwood had to do some repairs and they added a second layer.

with metal over it is best to do the pulins scewed right to the truss/rafter though the plywood then the metel screws to that.
If you strip it then metal metal does not handle wind driven rain to good around some places like then ridge caps so used a good #30 felt under it incase a little water gets under...Truss me I have see the test that we did on some metal roof that we were importing from south Africa

Chuck, there's always exceptions to every rule. /forums/images/graemlins/wink.gif /forums/images/graemlins/laugh.gif I'm living in a 1997 Fleetwood product now myself. And I guess you know that mobile homes are built to different standards for different areas, and of course, sometimes folks get away with doing things that really are not recommended. On a wall in the closet in the master bedroom, there is a sticker that shows what "wind zone" this house was built for and also shows the roof weight loading it was built for. I think, but don't know for sure, that the other manufacturers have the same information somewhere, if the owner has not removed it. Last year, my daughter got several estimates before having her double wide (a different brand) re-roofed and they all told her it had to be stripped instead of adding a second layer. The lady who owned this home had a son and two teenage grandsons who were going to re-roof it for her. So they bought a better grade of shingle than the originals, rented a trailer to haul off the old material, and got up there and stripped it. And since it was right in the hottest part of the summer, they learned how big that job is, and went next door where the crew was re-roofing my daughter's house and hired the professionals to put the new roof on this one. /forums/images/graemlins/laugh.gif I only sat in the shade and watched. /forums/images/graemlins/laugh.gif

if shingleing striping the old ones is always better. only way I would do a second is if the first was fairly new.....but it putting metal I would strip it right over the old ones...but that's me
