Our Devon roof is looking a bit tired a bit saggy and rubbing the gutters . I've been weighing up various repair options and talking it over with @PIE who told me of a late Devon top that was languishing behind a mates garage .so a trip to Shrewsbury today and I'm now the owner of a late Devon roof that although is in need some Tlc and adaptation will do very nicely.
Ah-ha, well, I had a devon with the same roof. Ugly thing. I gave it away and fitted a dormobile. That new later one is much nicer.
Get the fbre glass out! After glassing it a bit of filler and spray it, I wold keep well away from the gel coat!
