Mine leaked like a siv in the storms yesterday going through N. California. Last year when I had it put up it had a few leaks which I patched using that blackjack roof sealant in a caulking tube. This year though is crazy, The lawn tractor got soaked, I ran out of buckets trying to collect the water. I don't think the blackjack works good on steel. Any pointers? I made sure all the nuts, bolts and screws got there nylon washers as when my father had one put up they didn't use washers and it made for a worthless building.
No announcement yet.
Anyone familure with steel buildings?
