Everything is Based on Midpoints

It is essential to recall before we begin reviewing this too closely that these numbers are all depended on averages and midpoints. Your roofing system could last shorter, or considerably longer than the range given. As these numbers are here and say one thing that your roof will last precisely this long, don’t just assume that. All things are taken into consideration, these amounts rely on years of information and facts and have been monitored to be reliable throughout the years.

The latest definitive research study on roof system life expectancy gave the following lifespans for the most widely used roofing systems.

Spray-Applied Coatings

When we discuss coatings, we’re discussing silicone coatings. These are the coatings that we produce, and they’re not a system. Extend the life of that system, and they’re intended to be applied to an existing roofing system. Like the situation with SPF roofs, spray-applied coatings are still typically young roofing systems and don’t have the information which other roofing systems have. In any case, these systems can last up to 20 years, and some systems are promised up to 50 years. Towards the end be restored for another 10-20 years of service and of their lives they can be recoated with the product than applied. It is at this time unknown this procedure can go on before failing, because nobody has reached that point.


The maintenance required to permit your concrete roof to last its full expected life is a lot less than that required for a metal roof or most different systems so far. There are there is no roofing system that doesn’t require maintenance, but concrete is one of the toughest ones.


Among the more drawn out roofing system life spans in the study is that of EPDM, also called rubber roofs. In case you’re searching for an enduring and long roofing system with a price tag, EPDM is a decent option.


Depending on the analysis, metal is presumed to last anywhere between 30-45 years after installation. This lifespan has to be anticipated if the roof is maintained throughout the years. This could integrate regular painting if any fasteners become disengaged during roof motion to avoid substitution of panels rust, and refasten the roof. If the roof inspected and is appropriately and routinely maintained, it’s not irrational to expect your metal roof to last 35-40 decades or longer. The lifespan of a metal roof may range relying on metal picked’s sort, with a huge variety of metals available.

Spray Foam Roofing

Sprayed Polyurethane Foam, often regarded as SPF, most likely has the longest system service life in the study. We say because this system is extremely young and a large number of the first SPF roofs which were presented in 1970’s and the 1960’s are still in standing and operation. These roofs have endured for approximately HALF A CENTURY and hinted in no holding back, but no average has been figured out since the system is quite young. In spite of no answer in the life of this system, there are SPF roofing systems that, when coated and maintained properly, have survived giving SPF the system life expectancy of all roofing materials.
