The Single-Ply Roofing Industry (SPRI), representing North American manufacturers in commercial roofing manufacturing, education, and innovation, announced that the U.S. Single Ply roofing industry saw a 17.2% increase in 2022 roof membrane shipments against the prior three-year average as reported by SPRI Membership. Membership reported overcoming significant raw material and labor issues lingering in many industries in 2022, and increased membrane shipped to the market significantly in support of increasing annual market demand.   

SPRI membership comprises 62 total companies in the commercial roofing industry, including 20 commercial membrane manufacturers that participate in volume reporting.  SPRI member companies report shipments for several classifications of flexible roof membranes: thermoset, thermoplastic, APP modified bitumen, and SBS modified bitumen. Regular & Associate SPRI members enjoy access to this invaluable, proprietary report tracking these key industry product shipments. 

The thermoset segment saw a 6.3% drop, thermoplastic saw 24.5% growth and modified bitumen saw 10.4% growth in shipments over the prior three-year average. All categories have shown a decline in 2023. 

“Our members reported strong overall demand throughout 2022, as distributors and end users ordered products earlier in the roofing season and at a higher volume of square feet according to our data. SPRI reported growth in shipment square feet in all 4 quarters of 2022.  As we moved through the first half of 2023, members have reported declining shipments as availability of product in the market improved and supply challenges receded. This could be an indication of higher end user inventory utilization in the first half given sentiment in the industry and other publicly available data on the market.”  said Brad Van Dam, SPRI President.” 

Regionally, 2022 shipments increased 19% in the North East US.  The South saw 32.5% growth, followed by the North Central at 18.9% and the West with a 14.9% decline compared to the prior three-year average. 

SPRI members report shipments at both the national and state level in the United States, and Canadian volume nationally.
