Before we get into too much detail, it is important to remember that all these numbers depend on averages and midpoints. These numbers do not guarantee or insure that your roof will last the specified time. Roofing downriver MI your system may last significantly longer or shorter than the given range. These numbers do not guarantee that your roof will last this long. These numbers are based on years of data and facts from different scenarios. They have been continuously monitored and verified to be reliable over the years.

Spray-Applied Coatings

When we talk about spray-applied coatings, we are referring to silicone coatings. These coatings are made by us and are not standalone systems. These coatings are designed to be applied to existing roofing systems and prolong their life. Spray-applied coatings, much like SPF roofs in that they are often applied to young roofing systems, don’t have as much information as other roofing systems. These systems can last for up to 20 years depending on how thick they are applied. Some systems even have a 50-year guarantee. They can be re-oiled with less product than was originally applied, and then restored for another 10-20 years of service. The fact that no one has yet reached that point, it is not known how long the recoating process can continue before giving up.



Your concrete roof will last for its expected lifetime. This is a far better maintenance than what you would need to do with a metal roof, or any other system. Concrete roofs require some maintenance.


EPDM (also known as rubber roofs) is one of the longest-lasting roofing systems in the study. EPDM is an excellent choice if you are looking for a durable roofing system that lasts a long time and costs a small amount.



According to the study, metal should last between 30-45 year after it is installed. If the roof is well maintained, this lifespan can be expected. Regular painting could be used to prevent rust and replacement of damaged or inferior panels. Roof fasteners may also need to be refastened if they become loose during roof movement. It is reasonable to expect your metal roof will last for 35-40 years if it is properly maintained and inspected. The life expectancy of a metal roof will vary depending on the metal used. There are many metals available.

Spray Foam Roofing

Sprayed Polyurethane Foam (often referred to as SPF) is the most durable roofing system in our research. This is supposedly because the system is young. Many of the original SPF roofs, which were installed in the 1960’s and 1970’s, are still in use and standing. These roofs have been around half a century, and they suggest that there has been no fading. However, no average has been established because the system is still young. Despite not being able to give an exact answer about the lifespan of the roofing system, many SPF roofing systems have survived for 50+ years. This makes it the most durable roofing material.
