With mortgage rates hitting a two year high, pros are wondering if the strength in housing can continue.
Sales of new U.S. single-family homes vaulted to a five-year high in June, despite the average interest rate on a 30-year loan jumping to 4.46 percent, the highest since July 2011.
Although those rates are low historically, the Street remains uncertain that the sector can withstand further increases.
With housing at a potential crossroads, pros like Cramer often check in with companies in the heart of the industry to determine what's next.
"I'm still a believer in a housing, but I also know that we need to collect some evidence, and the way I do my research is by listening to what individual companies with boots on the ground have to say about the subject," Cramer said.
And few companies are as pegged to the health of the housing market as Owens Corning, the maker of insulation, composites and roofing materials.
