[RE-wrenches] galvanized barn roofing

[Mike Nelson]

I have used hanger bolts on this exact roof several times. Filled the holes
with copious amounts of a good polyurethene sealant (vulkem) before driving
the hanger bolt, then built up with sealant around the hanger bolt base.
Haven't had any leaks, always tried to stay on the ribs, above the water
line.
