- Notes on this entry
- The company’s own site states neither a headquarters city nor an explicit ownership sentence — it links to Cornerstone Building Brands careers in the footer. hqState NC is lower confidence, inferred from the 910 area code on the site plus Fayetteville, NC in parent materials. Reach recorded as regional: the parent describes the business as serving the central and eastern US.
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. Union Corrugating Company 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.
