I have gotten ten different answers from contractors. I am looking for the best possible way to install an exposed fastener "tuff rib" style panel roof over my shingles. Most tell me they will screw it directly through shingle to wood deck (without inspecting deck). Is this the best? It seems to me that a 7/8" galvanized steel hat channel or 1x4 slat "frame" would be stronger and could be secured to the rafters and make for a straighter roof. Would the airspace created by the second method need to be ventilated and if so how? As an alternative I considered "filling" the airspace with foam board to eliminate the airspace, but not sure if or how that should be done.

I think that the reason you are getting different answers is that there is no clear "best" answer. There is generally no reason that you must install battens but then again if the roof product you're installing is approved for installation over battens, there is nothing wrong with using them either. You could install vertical battens and then horizontal battens and then vent the air with eave soffit intake vents and ridge exhaust vent if you wish. this would help with energy efficiency of the home.

As far as inspecting decking, normally in most cases an inspection from the underside will show whether or not you have potential issues that, if you do, should be addressed.

I wonder though, how could you vent the space between the steel and the decking/old roof? Do they make a soffit vent intake for panel steel that is screened to keep insects out? Thanks again!	Guest User 4/22/2009	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/13149/find/
Yes, there are several ways of bringing air into the resulting chamber.	Todd Miller Isaiah Industries, Inc. 4/25/2009	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/13150/find/
Do you know of any place I can find a detail to show my contractor?	Guest User 4/28/2009	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/13151/find/
