How long does roof rejuvenation last, and how often should it be reapplied?

Lifespan and Reapplication

The manufacturer's guidance is to apply APEX-1132™ within about three years of a new roof installation and to reapply roughly every five years to keep shingles conditioned.

SoyLei also states, based on their testing, that the treatment can add up to six years to a roof's life. We want to be clear: that is the manufacturer's claim from their own third-party testing — it is not a roof-lifespan guarantee from On Top Home Services. What we stand behind is applying the product correctly and to manufacturer specifications. Reapplication timing can vary with your roof's age, exposure, and condition, which we assess at each visit.
