As many NRCA members and roofing professionals know, NRCA
revamped a number of its programs during 2004, and the
association's market survey was no exception. NRCA condensed its
annual market survey to focus on those roofing market areas most
important to roofing contractors: squares of installed roof
systems; sales of types of roof systems for low- and steep-slope
new construction, reroofing, and repair and maintenance work; and
overall sales volume trends.
NRCA first attempted to gather data for the survey by asking
about 2,000 NRCA member and nonmember roofing contractors in
September 2004 to respond to an online survey and compare their
experiences from 2003 and 2004. Although NRCA hoped it would
receive enough online responses to complete the report, this was
not the case.
NRCA then mailed the survey questionnaire to the same group of
contractors and received a total of 199 responses for a response
rate of 10 percent—enough to provide sufficient information
for the report. However, NRCA's market survey is not a
statistically valid analysis of the roofing market; it is intended
only to provide feedback from contractors about annual trends in
sales volume, squares and the types of roof systems installed.
