Hello,

Getting ahead of myself here, but let me ask while I think of it:

Live outside of Boston.

Will probably go for a new roof in the Spring.

How "necessary" or desirable is it to remove the old
shingles first ?

Seems like it would be a much bigger job if we have the Contractor
remove the old (25 years old, but still fairly good; no curling, etc.)
ones first.

What are the pros and cons, please ?

What else should I be asking the Contractor ?

e.g., what "grade" of Shingles for up here in New England ?
I imagine most of the cost is the labor; right ?

That Rubberized sheet I think the use as a matter of course:
How far back up the rood should it extend ? Further is better ?

etc., etc. ?

Thanks, appreciate your opinions,
Bob

My 2nd roofing was laid over first as you can usually do but I had some
curling on 1st and contractor suggested somewhat higher grade
architectural shingles which hid imperfections. It's over 30 years old
now and looks fine and has never leaked but at this age I'm going to
replace it which means removal of 1st and 2nd shingles.
