Is Felt Adhesive Enough, Or Do I Need Nails Too?

[youdontwanttodoitlikethat]

Just a couple of quick questions for the experts. I want to re-roof my small shed. It's a flat roof with a slight slope. It will need two strips of felt across it with a slight overlap. Is felt adhesive good enough to hold down the felt, or do I need clout nails along the overlap too?

And as it's cold this time of year and felt will be stiff, can I use my blow torch on felt to warm it a bit to help make the corner folds, etc? It's not actually torch-on felt, just the normal stuff.

Thanks for any help.

Nails as well.

Yes but don't heat it too much. BTW I once torched an overlay onto a roof for a cheapskate guy - the green mineral was type 1E, ie not torch on stuff. It worked ok but, again, I had to be careful not to heat too much.

I'd nail the sheet under the lap, and the eave and verges if there is no timber piece to secure those.
