It has been almost a month since we started jacking the roof up and we are finally putting the steel roofing on. Actually the timing also had to coincide with when our son had a break from college. Thats him working the eaves from the loader bucket.
I got to work up and down the roof doing the majority of the attaching. We used 1 1/2 color matching screws to attach the steel. One screw at each rib (5) and each purlin (10). So something like 50 screws per panel. You can't see real well, but thats a Milwaukee Decking screw gun, not a drywall screw gun. This type runs slower and has the optional nose piece that fits a nut driver bit instead of a screw driver bit, Its FANTASTIC for these screws, you set the depth so it compresses the rubber washer just right and go for it. No checking and rechecking depths, etc.
To get to this point we finished the purlins on each side. We installed a steel drip edge molding on the eaves. And we measured and snapped a chalk line up the gable that is square to the eaves. Basically you HAVE to get the steel running square to the eaves otherwise the overhang will change with each sheet.
Well, our line started out ok, but the foam inside closure strips that are installed at the eaves causes the panels to bow up in the center such that the panel is slightly narrower, by maybe 1/32 at the eave. Add that error up over 12 sheets and you get a bigger error. Needless to say our overhang is not perfect, but its waterproof !
And, No I had not trimmed the purlins to length on the other side of the roof, yet. We were fighting rain all weekend and we had a dry spell so we started putting on steel.. (I can walk on wet wood, I can NOT walk on wet steel - Can you say greased lightening..)
