It rather depends how long you plan staying there! Lead/Zinc are 80/40
years (impossible to say, really, but these are guidelines)

GRP (as your builder and the other poster says) 20-25

Ashphalt say 15-20 (not very common but I was offered this)

Felt 10-15

So a felt roof (x around 20+ locally to my knowledge) in perfect
condition at 40 years+ is unusual then? Then again the very well
regarded local builder was *extremely* good.


Ah, maybe if you could go back in time and get a felt roof 40 years ago...

I am always happy if felt roofs last longer than people expect (who wouldn't
be!). The figures quoted were what the builder(s) I have had said, are
certainly true of ones I have known round here and was true of mine, which
started to show problems at about 12 years and which was replaced at 15, by
which time it needed it! I would be planning to have the money for a
replacement in another 15 years.

It does also depend on how much sun it gets and if it is ever walked on.


My garden shed roof had the felt totally disintegrate after 8 yaers.
Cheap ****e agreed, but don't expect felt to be the be all and end all
of longevity.
