Not really powered equipment......

[Mark (EC,IN)]

.....but it's where I keep the powered equipment

Pulled over 3000 nails and put 1/2" longer screws back in the roof of a 30 year old Morton Building roof that had a few leaks....you could see where a few nails had pulled some.

I was sure when I went down this morning to check (first rain after the job was done) that it would be dry.....WRONG!!!

When I got to looking, it it is getting in where the metal overlaps, which means it has to actually flow up hill and around the bend to leak.



Ideas???

Are they full lenght sheets. If not they may be lapped wrong. When installing the bottom run needs to stay 2 sheets ahead of the top to prevent the top one from being over lapped by the next bottom sheet. Hard to see but the water has no problem finding it.

That can be aggravating as hell. Was this metal fastened in the flats or on the ridges? My hunch is telling me on the ridges, and the metal is ever so slightly deformed at several of the nail/screw holes at the seams.

Next best thing to replacing the dented metal is to smear caulking along the seams where the leaks are, make sure and cover several feet above where each leak is ... since the water is more than likely starting under the seam somewhere above where it's actually jumping 'over' the ridge to show up as a leak in the shed.

Simplest fix might be to paint the roof with aluminized paint. If you brush it on go over the seams twice.
