[AT] tin roof repair

[jtchall at nc.rr.com]

I had to swing by a building supply store yesterday anyway so I checked out 
what they have. I saw the coating that is rubberized and supposed to remain 
flexible---it looks promising. I've also had a product by Sherwin-Williams 
recommended to me. We've used something made by Kool-seal in the past, I 
just don't on what section of what shed got it. Some of the products we used 
in the past may be working well, however the black tar patches are 
definitely breaking loose in chunks. Certainly replacing nails with screws 
will help future leaks from developing, I've got to find a supplier for the 
screws in bulk,at $.10 each this gets to be real pricey. All of our sheds 
are pretty much in the open with no tree line to help slow down winds, so 
when a bad storm arises, they get hit pretty hard.

Thanks for the suggestions,
John Hall
