Hi Jay,
Just use your roofing sealant of choice: fill the pilot hole, leaving a
nice big dab on the surface. Because all holes are in the peaks of the
corrugations, the penetration point should see very little water there. In
my opinion, this is less risky than trying to seal the corrugations
Adam:
We used the Corrubracket, I thought they were sub-standard in many ways. I
dislike that the penetration is in the low point of the profile. Also, the
threaded hubs stripped easily. The overall feel was that it was flimsy.
We subsequently tried the SnapNRack Corrugated Roof Block
Adam,
I'm a big fan of the Corrubracket. We've installed hundreds of them on a whole
range of different types of corrugated roofing, with zero problems so far.
The peel-and stick sealant that comes attached to the bracket works really
well, but it can get pulled aside as the fastener goes
