If one gets a new asphalt? shingle roof with 20-year Monsanto? shingles,
how long should it last? 20 years?

Mine is only 13 years old and has a small leak already. I can't see the
back half of the roof from the ground, but the leak is in the middle,
not by the chimney flashing.

I watched them put it on and they did a good job. They used famous name
shingles, though I can't remember if it was Monsanto, 3M maybe.
My Ex got about 20 years out of her "20 year" roof about 40 miles
south of you. Here in Florida we pretty much plan on about 70-80% of
the guarantee.
The guarantee is pretty useless too. It is the pro rated cost of what
you paid for the shingles against the list price and does not include
labor (the last time I read one).

Not certain if my last house was 20 year but I think so. I got 22 years
out of them and probably could have stretched a bit more.

Never heard of anyone making out with a warranty though.
My last roof was a 25 year roof and it was WAY overdue at 13.

Â* How well ventilated is your attic space ? Heat buildup in the attic
space can have a dramatic effect on shingle life . I went with steel
here , has expected life of 40 yrs IIRC - and many here are older than
that and still look great .
