In one study, the Roofing Alliance for Progress compared roofs that had frequent inspections and repairs done to roofs that were maintenanced when they had problems. Data was gathered over a 15-year period. At its completion, the study reported some interesting findings:
For roofs with “reactive” maintenance programs, building owners and facility managers paid an average of 25¢ per square foot.
On roofs with “proactive” maintenance programs, building owners and facility managers paid an average of 14¢ per square foot.
The study examined low slope roof systems and found they have an average life span of 17 years.
On average, roofs with a robust maintenance program last for 21 years. In contrast, on average roofs that were reactively maintenanced only lasted for 13 years.
On a 10,000-square foot roof, those cost differences are quite wide-ranging. A reactively maintained 10,000-square foot roof would cost on average $2,500, and an actively maintained 10,000-square foot roof on average $1,400. That is a $900 cost difference overall.
