Building Materials Manufacturing, LLC will shut its Minneapolis facility and lay off 120 employees effective April 4, according to a notice filed with the state this week.
The roofing materials manufacturer that makes waterproofing and roofing products for GAF Corp. will permanently shutter its plant at 50 Lowry Av. N.
The reason for the layoffs was not immediately clear.
The Maple Grove warehouse is not impacted.
Building Material’s parent company is New Jersey-based GAF, which is one of the largest roofing and waterproofing companies in North America with 30 U.S. locations and 4,800 employees.
A GAF spokesperson reached Tuesday said the decision to sunset the Minneapolis plant was partially tied to the age of the building and equipment and the need to invest efficiently across its nationwide network, which stretches “coast to coast.”
GAF appears to be in the midst of some restructuring. A related company in New Jersey, GAF Materials, filed a WARN notice in New Jersey in October announcing it planned to lay off 106 employees at a location there.
Another related company, GAF Energy, filed a WARN notice in California in October announcing it was closing its headquarters in San Jose, Calif., affecting 138 employees. Solar shingle operations were expected to shift to a new solar plant in Georgetown, Texas, that opened in 2023.
