Any roofers here who could etimate (very roughly) what I could expect
to pay to have the roofing felt on my average size 3 bed house roof
renewed?

The felt has become dry and brittle and is letting rain in. I have done
temporary repairs with filler foam as I was renewing the ceiling
plaster boards, so had access to it. No attic space in my house.

I will be getting some quotes, but was just wondering if anyone here
had an idea what it might cost me.
