Roofing industry sees 12.2% shipment spike despite supply chain issues
A recent report from the Single Ply Roofing Industry (SPRI) identified a 12.2% increase in roofing membrane shipments in 2021, suggesting supply chain issues may be starting to dissipate.
This is a marked improvement from 2020, which saw shipments drop 4.1% year-over-year.
SPRI, the trade organization representing North American manufacturers in commercial roofing manufacturing, education and innovation, compiled this data based on sales reports from its 64 member companies. These member companies report shipments for several classifications of flexible roofing membranes: thermoset, thermoplastic, atactic polypropylene modified bitumen (APP) and styrene-butadiene-styrene modified bitumen (SBS).
In particular, the thermosets segment grew by 7.5% year-on-year, thermoplastics grew by 14%, and modified bitumen grew by 9.7%. Regionally, year-over-year shipments increased 20% in the Northeastern United States. The southern region grew by 13.5%, followed by the central-north region at 10.7% and the western region at 6%.
SPRI members in the United States report shipments at the national and state level.
