Quick answer
A properly installed silicone roof coating in Spokane lasts 15 to 20 years and can be re-coated at the end of the warranty for a fraction of the original cost, effectively giving the roof unlimited life.
The realistic numbers
Silicone: 15 to 20 years, renewable.
Acrylic: 10 to 15 years in the right conditions.
Fabric-reinforced systems: 15 to 25 years with less risk of tearing.
Spray polyurethane foam (SPF) with a silicone top coat: 20 to 30 years when re-coated on schedule.
What shortens a coating
Skipped prep, wrong mil thickness, coating over wet insulation, and clogged drains are the top killers. None of them are the coating's fault, they are install and maintenance failures.
The habit that keeps yours going
Walk (or have us walk) the roof twice a year. Clear the drains, spot-check the seams, and touch up any nicks. A ten-minute visit prevents 90 percent of premature failures.
