When you say another layer, how many layers are there now? If it is
more than one, don't try adding another. If fact it is really better to
tear off and get any old problems out of there.
As far as the choice, it might be helpful if you tell us where you are.
Washington State is far different than New York and they are different than
Arizona or Florida.

I would definitely go with steel shingles if you are looking for an
easy DIY re-roofing material. Especially in a hurricane region. You
dont have to take the old asphalt shingles down. You can buy steel
shingles on ebay:
just make sure you dont get screwed by this seller (see previous
thread for details). Also, you can contact these wholesalers:

or mfgs: accelroofing.com, custombiltmetals.com, edcoproducts.com,

Just my experience: I reshingled proffesionally back in 1998. Not one
contractor (out of 5) would quote me fiber glass shingles. Everyone told me
they didint hold up to Chicago's climate. Now its 2008, new house, and I
have to do some patching. I go to a big box store expecting to buy Asphalt
shingles. Not one store carried them. All Fiber glass. I suspect which is
better is going to boil down to whats sold in your area.
Easy way to find out on code? Call a contractor, tell them what you are
proposing, ask them to price out any work if you find you have more than
just some reshingling needs (like I needed 2 plywood panels replaced so we
ended up doing most of them as cheaper then and didnt have to deal with it
later). As long as you are honest and tell'em you plan to do it yourself
but want info if you find worse damage, they'll be happy to help over the
phone with general info.
It was 8 years ago and we were told 90$ per panel for the good wood and 150$
each to replace. Plus haul away fees. We ended up having the whole thing
done professionally because we couuldnt find a match for the old roofing
shingles. (and of course the new shingles and it's install added more cost)
Your price may be higher as ours was part of a package deal to also reside
the house with vinyl.
Sorry, I do not know which type of shingle is better, but your codes
*probably* are fine with 2 layers as you are just south of me so same
overall construction. If there would be a difference, I susect it's that we
have to account for snow here too (weight on roof), so we may be a little
stricter on number of layers?
Being in NC (I was in Fayetteville for a bit), be sure they are AR (Algae
Resistant) shingles. Black algae just thrives in the humidity there.
Never did get hit with a hurricane when I was there. Lucky. Highly
recommend not using staples (if it's even legal where you are). Use nails
and consider the "high wind" nailing pattern recommendation of the mfgr
(greater than 4 nails).
Joseph, I'll add to your post that in my area at least, codes do not allow a
3rd layer. Norfolk area, storm related issues. We arent 'hurricane alley'
but we get hit often enough. It's that and the weight which can cause major
long term damage I am told.
A DIY job by a fellow down the street was 3 layer and the random (1-2 times
a year) inspector caught it and made him take it all off. He got fined too
but I dont know how much. He hadnt known it wasnt allowed here (good fellow
actually) and said '3 was ok where he came from' which leads me to believe

Your question doesn't make sense. Both fiberglass and organic mat shingles
contain asphalt. From your perspective either one will work fine.
Fiberglass has a slightly better fire rating. Make your choice based on
appearance and the life of the warrantee.
Asphalt shingles are either asphalt reinforced with fiberglass or
asphalt reinforced with cellulose (organic), but I've heard of some
being made of asphalt reinforced with polyester.
The Aug. 1997 Consumer Reports found that organic shingles always did
very well in freeze-thaw tests, but a few fiberglass shingles did,
too, including GAF Royal Sovereign.
I'd much rather have fiberglass shingles because of their much better
class A fire resistance rating. There have been some residential
fires where the fire spread along class C asphalt-cellulose shingles
but stopped right where the class A fiberglass shingles started, in
one case in a Houston apartment complex. Class A isn't just a
slightly better than class C; it's a lot better.
