[AT] Screwing roofing

[Cecil E Monson]

	Just over 3 years ago I put up a new shop that is 36' X 48'.
It has steel roofing - 4 flats and 5 ribs to the sheet, approx 3' wide -
and screwed down with 1 3/4" hex head screws with washers under the
heads that were made for this application. The screws are next to each
rib and go thru every roof purlin all the way up. These sheets of steel
are full length so there are no seams. Not one of the screws on my roof
has worked loose and I would not expect them to. I only had one small
leak and that was where one of the guys putting on the roof missed a
purlin. The men who put up this building for me have specialized in
building these sheds for municipalities and farmers for many years and
have had nothing but compliments on their buildings. It would take a
helluva wind to pull any of this steel off a building. FWIW, every hole
for the screws was drilled before the screw was installed. I believe
they used 3/16" drill bits for this.
