Holes in tin roof sheets.

[tepapa]

I have a few holes in the shed roof after reusing old tin sheets

What's the best sealant I can use to block them up to stop the leaks?

Hopefully someone knows before I go and experiment ? .

The best thing I’ve found is to stick patches over the holes with flash band.

Got any spare sheets you could cut patches to either bolt or stick over the top of holes? Bit of sealant sguidged in between should see you right?

What you need is a some decent quality plywood cut into 2" squares, with a small pilot hole drilled in the centre of each one. Then use a standard tek screw for timber down through the old hole into the piece of ply, which gives the tek screw something to pull down on. The hole is thus made water tight by the tekscrew, as if it had been screwed into a rafter. I repaired a 8 bay lean-to using this method after the old guys who erected it had used spring head nails on profile sheeting - this was in the early 80s, they'd only ever used corrugated tin, they'd never seen profile sheeting before! Biggest problem is its a two man job, one on top, one below. Easiest when the shed has bales in of course. But the roof I did has never leaked again since I used the above method on it.
