if a rubber roof is left alone....not scrubbed or treated it should last 15 to 20 years. The product was developed for flat commercial building roof and exactly how many have you ever seen scrubbed or treated????

And around here they can last well over 30 years because they don't get the UV damage seen in other locals.
