Leave it to the roof scientists.
Remaining useful life of a roof.
Too many building owners and facility managers agree to roof replacements prematurely with years of life still remaining in their roofing systems.
For example the remaining useful life of a roof with a pvc membrane that was installed approximately seven years ago and was poorly maintained might be approximately ten years.
The average life of the premium white roof in our example is greater than 20 years.
The remaining useful life is estimated based upon observations or average estimates of similar items components or systems or a combination thereof.
Materials and workmanship as well as the weather elements in your location determine the lifespan of a roof.
How knowing remaining useful life and depletion rate can work for you.
Your primary roofing objective should be to delay a costly roof replacement.
Our research sources indicate that the average life of the premium black roof in our example is 13 9 years.
The cost of a steel roof depends on the sheet profile the finish applied and the size and shape of your roof but offer excellent durability with a lifespan of 50 years or more.
Between our in house lab and a partnership affiliation with youngstown state university we developed a series of membrane tests that we packaged together in a proprietary way to accurately determine the remaining useful life of a commercial roofing system.
