I need to put on new shingles and it will be a tear-off job since there are least two layers now.

My question is, living in central Minnesota, which is the better choice of shingles; fiberglass mat or organic mat?

I've spoken to several local roofers and have received about a 40/40/20 response. The 20% not knowing there is more than one type of shingle construction (beyond appearance).

Most of those saying organic mat said they don't trust fiberglass shinges.

Most of those saying fiberglass said it because that is all they have ever used and is a more modern technology.

Guess I'm looking for more of a scientific or "have done it both ways and why" explaination to help me choose one over another.

Thanks in advance!

I've done roofing since the late sixties and done almost every kind there is in that time. My responce has to be 40/40/20 too!

The theory behind fibreglas mat makes it a better shingle and longer lasting. For a time though there were problems with the production that have been ironed out but some roofers developed a distrust for ashingles with fibreglass mat. I installed some of the first fibreglas shingles way back when in a sort of beta testing [not what it was callled back then] and have always liked them.

Either will do a decent job. The more important thing is the quality and reputation of the installer than the materials package, IMO. Those who don't even know abvout the differences are obviously inexperienced - shingle installers only - not roofers.
