from the NRCA website:

The COVID-19 pandemic has affected the roofing industry in numerous ways, including leading to a widespread shortage of materials. The prices for materials have been increasing, and supply chains have been disrupted as lockdowns, tariffs and other factors cause delays and limited availability. In response, NRCA has made available a Supply Chain Shortage Information webpage to help its members stay up to date with the latest news regarding materials shortages and price hikes in the industry.

The new page also houses a recording of NRCA’s April 22 Live Action Alert: Supply Chain Shortages, during which NRCA CEO Reid Ribble and NRCA Vice President of Technical Services Mark Graham discussed the materials shortage issue facing the roofing industry.  Visit the Supply Chain Shortage Information page on the NRCA website for more information.
