Roofing wholesale prices hold steady in September

U.S. wholesale prices of asphalt roofing materials in September remained flat for the third consecutive month, according to Bureau of Labor Statistics (BLS) data released Thursday.

What’s happening: A roofing-specific ‘producer price index’ (PPI), which measures the average change over time in the selling prices domestic manufacturers receive for their products, hasn’t budged since July. 

• Since PPI measures price changes at the wholesale level, it’s generally used to gauge inflation before it reaches consumers. 

Zoom out: The overall, economy-wide PPI in September rose 1.3 percent month-over-month, the fastest rate in four years, drastically outpacing economists’ expectations. Inflated energy prices driven by the war in Iran contributed to the jump, per news reports. 

State of play: Compared to September 2021, the roofing-specific PPI is up more than 28 percent, including a roughly 15 percent rise from April to July 2026 alone.
