EXAMPLE OF COST-BENEFIT ANALYSIS OF PREVENTIVE MAINTENANCE PROGRAM
Assume a new 40,000 SF roof is installed at a cost of $5.00/SF: | 40,000 x $5.00 = $200,000 Total Cost |
Warrantied
Life-Span: | $200,000 ÷ 10 years = $20,000 cost per year |
If preventive maintenance program costs $0.02/SF per year, the total maintenance cost would
be: | 40,000 x $0.02 x 10 years = $8,000.00 |
Therefore, the average cost of the new roof per year would be: | $20,800 |
However, it has been shown that a
successful preventive maintenance program can increase the useful life of a roof by 50% or more. Extend the life to 15 years,
and the average cost of the roof per tear would be: | $13,867.00 |
Therefore, in this example, an increase of 4% in the initial budget resulted in an annual savings over
15 years of 30%. In addition to extending the life of the roof and increasing the annual cost-benefits of the initial investment,
the preventive maintenance also helps defer major capital outlay for reroofing. Using preventive maintenance to extend roof
life is very cost effective, but to realize the full benefits of a maintenance program, it must start when the roof is new
and be consistently followed.
