One of the roofing companies I am getting an estimate from uses
CertainTeed Landmark shingles. I had never heard of them before. Are
they comparable to GAF and Owens Corning?

Also - my husband and I are unable to agree on something. He thinks
the shingles sold as being okay up to 80 mph are sufficient for us
(Tampa Bay area) and I want the 110 mph kind. The 110 mph kind cost
$1000 more (approximately) but I figure the peace of mind is worth
it. Anyone here have any actual experience with hurricane winds and
shingles. Thanks.
