The remaining useful life is estimated based upon observations or average estimates of similar items components or systems or a combination thereof.
Remaining useful life of a roof.
We ve proven it through our laboratory testing.
Leave it to the roof scientists.
Our research sources indicate that the average life of the premium black roof in our example is 13 9 years.
The real life of a roof can vary greatly depending on the conditions in the roof s local environment.
Materials and workmanship as well as the weather elements in your location determine the lifespan of a roof.
Your primary roofing objective should be to delay a costly roof replacement.
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.
While many types of roofs last longer than 15 years some can hold up well for 50.
The average life of the premium white roof in our example is greater than 20 years.
