Ten year old covering. Adequate ventilation throughout attic but all of the shingles were cracked. I don’t typically see this much cracking on asphalt shingles at ten years.
Can’t tell much more then what I’ve said except there is cupping in your other shot and most laminates that I’m aware of have a 25 yr or more warranty. Not that this helps you or them in any way. Shingle warranties are worth the paper they’re written on only in the “Throne room”.
The look like the 3-tab shingles with the asphalt applique layering on them, similar to the Certainteed Horizon Shangles.
There was another brand made the same way.
Are there actually any laminated pieces of additional shingle adhered onto the bottom shingle body or if you wiped your hand over the surface, does it feel like a raised hump with additional asphalt?
