Tiers and designations, named as the company names them:

- Ownership
- Current parent is Amrize (NYSE: AMRZ), not Holcim. Malarkey’s own history page states that Holcim acquired Malarkey in 2022 and that Holcim then "spins off its US operation to become Amrize (NYSE: AMRZ) and the new parent company of Malarkey" in 2025.
- Notes on this entry
- Ownership correction: describing Malarkey as Holcim-owned is now out of date. The Amrize logo and "Amrize Terms of Use" appear in the malarkeyroofing.com footer. The Holcim acquisition was announced 2021-12-23 (https://www.malarkeyroofing.com/holcim-to-acquire-malarkey-roofing-products/). Malarkey uses "Emerald Pro"/"Emerald Premium" as associated WARRANTY names; those pages were not read, so the warranty naming is not asserted here.
Where this came from
Details on this page were confirmed from the company’s own site on August 25, 2026. The page that was read. That is a record of what the company publishes about itself — not an endorsement, a rating or a check of its work.
This entry is editorial. Malarkey Roofing Products did not pay to be listed, has no control over what it says, and appears here because it operates in this part of the roofing industry. Companies change their programs, their ownership and their product lines without announcing it, so treat the date above as the age of this information and confirm anything you are relying on at the source.

Hiring a roofer, rather than buying from one of these?
Manufacturers, distributors and B2B companies do not install roofs. The contractor directory is a separate part of this site, organised by state and then by city — start there, and check licence and insurance with the state board before work begins.
