When we discuss spray-applied coatings, we discuss silicone coatings. These are the coatings we manufacture and they are not a device that is standalone. They are supposed to be added to an already existing roofing system and to prolong the life of that system. Spray-applied coatings are still usually young roofing systems, just like the case with SPF roofs, and do not have the definitive knowledge that other roofing systems have. In either case, these systems, depending on the application thickness, can last up to 20 years and some systems are expected to last up to 50 years. They can be recoated with less product than initially applied at the end of their lives and restored for an additional 10-20 years of service. How long this recoating phase will go on until it fails is uncertain at this time due to the fact that nobody has yet reached that point. Visit Top Glaze Roofing Systems.
One of the more drawn out lifespans of the roofing system in the study is that of EPDM, also referred to as rubber roofs. If you are looking for a long and lasting roofing system with a fair price tag, EPDM is a good option.
Metal is assumed to last anywhere from 30-45 years after installation, based on the report. If the roof is preserved over the years, this lifetime must be expected. If any fasteners are removed during roof movement, this may incorporate frequent painting to prevent corrosion, repair inferior or damaged panels, and re-fasten the roof. It is not unreasonable to expect your metal roof to last 35-40 years or even longer if the roof is regularly and properly maintained and inspected. A metal roof’s lifetime can also vary depending on the type of metal chosen, with a wide range of metals readily available.Sprayed polyurethane foam, also known as SPF, is most likely to have the longest service life of the roofing system in the sample.
