It’s all focused on midpoints,
Just before we begin to analyze this too closely, it is important to note that these figures are all dependent on midpoints and averages. None of these numbers are a guarantee or insurance that the lifetime of your roof will fall within the range specified. Your system could last considerably longer, or significantly shorter, than the range provided. Since these numbers are here and say one thing, don’t just assume that your roof will last exactly this long. All things taken into account, these figures depend on years of information and facts from different situations and have been monitored over the years to be accurate. Have a look at Top Glaze Roofing Systems.
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.
The maintenance required to allow the full expected life of your concrete roof to last is far less than that required so far for a metal roof or most different systems. There is some maintenance that should be performed, no roofing system that needs no maintenance, but one of the least demanding is concrete.
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.
