Atlas — Pinnacle Pristine, Pinnacle Sun, and StormMaster Shake.
The three Atlas shingle lines Atrium installs, the technology built into each, and what Atlas Pro Plus makes available on your warranty.
Atrium holds Atlas Pro Plus
Training and insurance requirements that enable the enhanced Atlas system warranties.
Pro Plus is Atlas's contractor certification program, held at the company level and verifiable in Atlas's own contractor directory. It's what makes the enhanced Atlas system warranty available on our installs. The full explanation is on our brands and certifications page.
The three lines we install most
Atlas makes more than these three, but these are the ones that show up on Atrium proposals.
Atlas's standard architectural shingle, finished with 3M™ Scotchgard™ Protector for algae resistance. Broad color range, dimensional shadow lines, and UL 2218 Class 3 impact resistance.
The cool-roof path on our THERMALGUARD™ system. Built with 3M Cool Roofing Granules designed to meet Cool Roof Rating Council Solar Reflectance Index standards, and finished with 3M Scotchgard Protector and 3M Smog-Reducing Granules. UL 2218 Class 3 impact-rated.
See it on THERMALGUARD™Atlas's flagship shingle, built with Core4® Technology and finished with 3M™ Scotchgard™ Protector and 3M™ Smog-Reducing Technology. Features Atlas's HP42® shingle technology, a wide nailing format, and a double FASTAC® sealant line. UL 2218 Class 4 impact-rated, with a Class A fire rating.
Availability varies by line and region
We bring current physical samples to your in-home consultation rather than publishing a fixed list here.
Atlas offers a broad color range across Pinnacle Pristine, Pinnacle Sun, and StormMaster Shake, and availability shifts by region. If you have a color in mind, tell us during your assessment and we'll confirm current availability for the specific line before anything is ordered.
The manufacturer's warranty first. Ours underneath it.
A manufacturer-backed system warranty ranks above any contractor's own warranty for one reason: it survives the contractor. If a roofing company closes, changes hands, or simply stops answering the phone, a warranty backed by Owens Corning or GAF is still honored. A contractor's warranty is only worth as much as the contractor still being in business, and that is as true of ours as it is of anyone's.
Pinnacle Pristine, Pinnacle Sun, and StormMaster Shake installs
All three are eligible for the Atlas Signature Select Roofing System Limited Warranty, available at Pro Plus standing, available because Atrium holds Atlas Pro Plus. It requires a complete Atlas system — shingle, underlayment, and accessories — to be installed, not the shingle alone. These are contractor-certification-tier warranties, not shingle-tier ones, so the ceiling is the same across all three lines. The tier-by-tier detail is on our brands and certifications page.
Atrium's workmanship layer
Atrium backs every roof replacement with a written 10-year workmanship warranty. It is non-prorated, so coverage in year ten is identical to year one, and it is fully transferable to the next owner. If a covered installation defect appears, we cover the labor and the materials to correct it.
The warranty covers the roof replacement we performed. It is our installation of your new roof system that carries the ten years.
It covers our installation, and that is all it covers. It is not insurance and it does nothing for hail, wind, or anything else an insurance claim would handle. The manufacturer's warranty on the shingles themselves is a separate document.
Whichever warranty applies to your system is registered in your name and delivered as part of the Power Package — the five documents every Atrium customer receives at closeout.
