Allan Reid Dura-Loc Roofing Systems, Inc. 1/17/2006	First I would not use an ag panel on a residential roof and over insulation as the extra heat will shorten the life of the coating which was not designed for this use. Also the residential building code calls for a 1" min vertically vented air space over the insulation. I doubt that it is a 25 ga and probably more a 29 ga. I would place the fasteners in the top of the profiles and certainly set my clutch adjustment on the screw gun to not overtighten the rubber washer. The best hoice is to strap the roof and fasten int the strapping.	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/7414/find/
