Roof restoration projects generated about 85% higher gross profit per crew day than traditional reroofing work, according to a benchmark study released by APOC.

The manufacturer of liquid-applied roof restoration products said the study, conducted with Cotney Consulting Group, analyzed 118 commercial roofing projects comparing restoration methods with reroofing approaches.

The report found restoration projects averaged about $8,000 in gross profit per crew day compared with roughly $4,300 for reroofing projects.

The study also found restoration projects typically required smaller crews and shorter completion times. A 30,000-square-foot roof restoration project averaged about eight crew days to complete, compared with 13 crew days for roof recovery projects and as many as 30 days for tear-off replacements.

According to the report, restoration work required up to 85% less labor intensity than tear-off projects and produced average gross margins of about 43%, with most projects ranging between 30% and 60%.

“At a time when contractors are under pressure to do more with less, this research provides clear, quantifiable evidence that restoration is not just a viable alternative, but it’s often the smarter business decision,” said Johnny Walker, national technical manager for APOC.

John Kenney, a research consultant for Cotney, said the findings provide measurable data supporting long-held industry assumptions about restoration profitability.

“Finish faster, run a smaller crew, keep more margin,” Kenney said. “That’s not theory anymore, now we can show you the numbers.”

APOC said industry estimates suggest 30% to 50% of roofs that are eventually reroofed may qualify for restoration, depending on roof condition and contractor evaluation.
