Daryl,
AEE has a corrugated
roof block that works pretty well. Penetrations are through the
ridges, where leaks are less likely, and they can be sealed with Butyl
tape. One draw back, same with the EJOT, is that the metal ridges will
rarely line up with support structure below. You'll need to
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

Interesting that it seems the industry is moving back to L-feet and sealant?
Always worked for many situations.

These sort of look like a "hanger bolt" but they are machined to cram down
on a fat rubbery washer as they are tightened. EJOT is showing up in some of

Hi Daryl,
I have drilled a small pilot hole, put plenty of sealant around it, then lag
through it with what ever foot you are using.
I don't think the cost of flashing around each foot with a rubber boot and 15
screws is any better but its sure more costly in time and money.

barn roofs around here, but I hesitate to penetrate any metal roof. How
have others dealt
