Since my previous post I contacted one of the main suppliers in the area and it took over a week to get a quote and never did get anything in writing with specs....just a ballpark figure. So I contacted another reputable supplier today and got two quotes back by late afternoon. One for Gavalume for $4,400 and the other for aluminum for $7,200. This includes tax and delivery to my property.
Both for standing seam (striated) .24 Gauge for the Gavalume and .32 for the Aluminum.
For the difference in cost I will go with the aluminum - pretty much a no-brainer - especially considering how close I live to the ocean with salt air corrosion being a concern for anything metal.
This company really did a nice job with the quote. Everything line itemized even down to the shipping and crating fee. Stainless fasteners included along with sealant, drip edge flashing, gable/rake trim, ridge cap, and some other odds and ends.
I will still have to buy underlayment but that's no biggie.
I'm filling out my permit right now and will call my install crew tomorrow and check their schedule.
This is what I will be using - the bottom one with striations:
