For The Way Lengthy Will Your Roofing System Last?

Everything is Based on Midpoints

It is crucial to recall just before we start reviewing this too closely that these numbers are all depended on midpoints and averages. None of these numbers are an assurance nor insurance that your roof lifespan will fall in the range given. Your system could last considerably longer than the range given, or significantly shorter. Because these numbers are here and say one thing that your roof will last precisely this long, do not just assume that. All things taken into consideration, these numbers rely on years of information and facts from various scenarios and have been monitored to be reliable throughout the years.

Roofing System with the Longest Longevity?

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

Spray-Applied Coatings

We’re discussing silicone coatings when we discuss spray-applied coatings. These are the coatings that we produce and they are not a standalone system. They are intended to be applied to an already existing roofing system and extend that system’s life. Much like the case with SPF roofs, spray-applied coatings are still typically young roofing systems and don’t have the conclusive information that other roofing systems have. In any case, these systems can last up to 20 years counting on the application thickness, and some systems are promised up to 50 years. Towards the end of their lives they can be recoated with less product than initially applied and be restored for an additional 10-20 years of service. It is at this time unidentified how long this recoating procedure can go on before failing, due to the fact that nobody has reached that point yet.


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


One of the more drawn out roofing system lifespans in the study is that of EPDM, also known as rubber roofs. In case you’re searching for a long and enduring lasting roofing system with a reasonable price tag, EPDM is a decent choice.


Based on the study, metal is presumed to last anywhere between 30-45 years after installation. This lifespan must be expected if the roof is maintained throughout the years. This could integrate regular painting to avoid rust, substitution of inferior or damaged panels, and re-fastening the roof if any fasteners become disengaged during roof movement. If the roof is routinely and appropriately maintained and inspected, it is not irrational to anticipate your metal roof to last 35-40 years or even longer. The lifespan of a metal roof can likewise range relying on the type of metal picked, with a wide variety of metals readily available.

Spray Foam Roofing

Sprayed Polyurethane Foam, often regarded as SPF, most likely has the longest roofing system service life in the research. We say supposedly on the grounds that this system is very young and a large number of the first SPF roofs that were presented in the late 1960’s and mid 1970’s are still in operation and standing. These roofs have endured for around HALF A CENTURY and hint at no holding back, but no average has been figured out because the system is rather young. In spite of no legitimate answer on the life of the system, there are many SPF roofing systems that, when coated and maintained properly, have survived 50+ years, giving SPF the longest roofing system life expectancy of all common roofing materials.
