GAF HDZ Shingles - Amish

[Toro50cutter]

Hello, all.

Our 19 year old architectural roof is on its last legs. As a result, we are replacing it this summer with GAF HDZ shingles. We’re utilizing an Amish company who is certified through GAF.

My question is, how do these hold up? The roofer is using GAF’s tiger paw underlayment, ice and heat shield, new flashing, an GAF newer all metal pivot covers for our roof exhaust’s. Additionally, I was told by their owner they will be using galvanized nails. He assured me they do not rust and will last longer than the roof.

Your help and guidance is appreciated.

We had those shingles installed last year; pewter gray. No issues but none expected. Any issues now would be the fault of the installer.
Glad to hear you're using the underlayment & the ice/heat shield. Are you having them install the ice/heat shield around the perimeter or just in the valleys? I realize up north it's required (?) around the perimeter, but it's not here in Alabama. Below is what we did.

Tiger Paw underlayment, StormGuard Ice & Water shield in valleys, behind flashing & siding, along front gable wall, at all roof penetrations, & as well all of perimeter, WeatherBlocker starter shingles, Cobra Rigid Vent 3 installed end-to-end, TimberTex hip & ridge cap, Master Flow pipe covers, drip edge/gutter apron

This was $27,000 for 81sq.

Here's what I had found about the fasteners when I was looking into it. Fasteners must comply with ASTM F1667 and be minimum No. 12 gage (0.105 inch), 3/8 inch diameter head, galvanized, stainless steel, aluminum or copper corrosion-resistance nails. Fasteners must penetrate into the deck minimum 3/4 inch, or through the deck, where the deck is less than 3 /4 inch thick.

Yes, ice and heat around the entire roof to prevent any side rain/ice/snow! They’re also doing everything you stated including the valleys and edges.

Roughly 33 squares although I believe there should be extra.

$15,400. It’s by far the cheapest quote we received. We received other quotes between $19,200 all the way to $35,000. It doesn’t help that it’s a well developed neighborhood with some large homes, but some contractors have pricing that was absolutely insane.

Thanks for the thorough reply. You made our decision even more cemented!

They can install as soon as late July, but should we ask them to delay until even August or September? I heard “horror” stories that roofers damaged shingles from walking on them due to the heat. It sounds far-fetched to me but this is the first time I’ve owned a home which needed a new roof.

Does your price include the English driver? That can add a bit of money
When dealing with the Amish...
Best of luck... my roof is 27 years old but looks good but I'm at the pricing stage.

In my area in Ohio , GAF shingles have the most problems. There are many roofers who won't install them.

Don't get hung up on the Amish. They are no better than any other good roofing company.

He did not say, but I can only assume. The contract he sent mentioned nothing of it. Their company has almost 400 reviews online and every single one is 5 stars.

Why is that?

I was told their LayerLock has essentially stopped any problems and that other manufacturers will copy their design when allowed to.

Probably Mennonite. They can drive and use power tools.
