A lot of Southlake and Keller homes built or reroofed in the 2010s got Atlas StormMaster Slate, a Class 4 slate-look shingle that was popular for the impact rating. If you have one, there’s something you need to know before the next hailstorm: Atlas discontinued it.
I’m Blake Snow. I’ve roofed for 30 years, and Snow Roofing & Exteriors is certified with Atlas. Here’s what the discontinuation means for repairs, insurance and matching.
What Atlas said
An Atlas product announcement, published in full at representation.claims, says StormMaster Slate was discontinued effective January 1, 2023. The same announcement says, in Atlas’s words:
“There are no other competitive asphalt shingles in the market that directly match the dimensions, color, and style of Atlas StormMaster Slate.”
Atlas’s own shingle selector no longer lists StormMaster Slate among its product lines.
How to tell if you have it
StormMaster Slate was a Class 4, slate-style shingle with a wider, flatter tab than a normal architectural shingle. Later production carried Atlas’s Scotchgard Protector algae resistance. The best ways to confirm:
- Your original contract, invoice or warranty registration.
- A leftover bundle wrapper in the garage or attic.
- A careful measurement of a loose piece, since its size and exposure differ from standard laminates.
Don’t guess from a photo. Plenty of slate-look shingles look alike from the yard.
Why it matters for repairs and hail claims
If a few shingles are damaged, the first question is whether matching material exists. Some suppliers may still have stray bundles, but color varies by run and plant. If no true match is available, a “repair” with a different shingle can leave a patch that looks and seals differently from the rest of the slope.
That’s why I document a StormMaster Slate roof slope by slope, measure a real piece, and attach Atlas’s discontinuation notice to the file. Then the adjuster can see in writing that Atlas says nothing on the market matches. Whether that leads to a partial or full replacement depends on your policy and the damage, not on me. I just make sure the facts are documented.
Your warranty still counts
Discontinued doesn’t mean defective, and it doesn’t cancel your warranty. Atlas’s limited warranty covers manufacturing defects for the term in your warranty. Hail is an insurance question. Keep the two separate.
What Atlas makes now
If you’re replacing, here’s what Atlas currently publishes:
- Pinnacle Pristine: architectural shingle, UL 2218 Class 3 impact, wind warranty up to 160 mph, Scotchgard Protector, 42” × 14” with a 6” exposure (data sheet).
- StormMaster Shake: Atlas lists it as Class 4 UL 2218 with wind coverage up to 150 mph (Atlas Scotchgard chart).
Neither is a slate profile. If you want the slate look back with a Class 4 rating, we’ll walk through other certified brands’ slate-look shingles, synthetic slate, or metal. Our Atlas page, Class 4 shingles and slate and shake look pages compare the options. Before you order, check that the product is on your insurer’s list if you want an impact-resistance credit.
