Holes in shed roof

Good loser

Round roofed shed 50/60 years old. About 7 small holes (showing daylight) high up on the round. Curved steel trusses and 3 inch angle iron carrying the zinc.

Any suggestions please on how to fix the holes? Largest hole say 4 sq inches.

Cut patches from "torch-on" roofing felt.
Partially melt them with a blowlamp.
Slap them over the hole.
Wear leather gloves when at this.

The biggest is 4 sq ins. The situation has been stable for 5/10 years.

The torch on felt solution sounds good. Think I'll do that. For obvious reasons it's empty this year.

Holes always rust at the nails, so be careful the timbers aren't rotten when you attempt to fix it.
If the sheets are also screwed together with bolts, those roofes are almost self supporting.

Another idea might be to use ( Fibre Glass Repair Kit ) Its meshing & paint on Glass Fibre. Easy to do & won't rust. Again to reiterate, be careful. Ideally use a roofing specialist, if not & you decide to fix yourself, suggest, Use safety harness with scaffolding or cherry picker. P

Still think you're best option is to replace the sheets and the timber if rotten.

Anything else is only going to be a stop gap job and you're going to have to re-roof eventually anyway.

Have similar situation here. Shed has done it's time so looking at TAMS to put up a replacement next year. When u start repairing them at that age I wouldn't trust timber or steel

No timber on this roof. Steel trusses and 3 inch angle for the purlins. Think the sheets are bolted together.

I won't be around eventually!
