Shed Roof

Fatman

Are there any alternatives to the felt on a shed roof?

Ive renailed it in twice now and it keeps comign off!
Ive heard about bitumen, but dont know much about it?

Thanks

You could fix Onduline on top of the roof provided you have enough cross timbers underneath to take the screws. I did this for someone and it lasted longer than they did, and the shed, for that matter!

There are different grades of felt. I always use the heaviest one, but I put it on with the black, rubbery gunk that you're supposed to put under the overlaps. You do stick the overlaps as you nail them, don't you? If not, that could be part of the problem.

If roofing felt is coming off, there might also be a problem getting the nails to hold, possibly because of particle board underneath being spongy. If this is the case you may have to add battens at the edges to get a better fixing. Depends on the construction, really.

Some thin batons such as doorstop (25mm x 10mm).

Nail them arround the outside edge and a few in the center.

i use torch on mineral felt...

but i do not torch it on :eek: i just nail it.

and yes good idea to frame it at the edge.
