There are lots of slipped slates on my roof, with rusty nails,
the local builder recommends reslating the whole roof
rather than patching it again and again.

At the moment there is no felt, he advises felt,
is there any reason not to use felt?

or is there an even better option?

I will use a professional for this
as I almost broke my back in a fall a few years ago,
and ladders scare me!
