Question

Can I do roof rejuvenation myself?

The product side is the easy part. The roof is not.

Even coverage matters, because a patchy application gives you a patchy result and there is no way to tell from the ground. Repairs have to happen first. And walking a roof safely is a real skill, especially on the steeper pitches common through Cottonwood Heights and Park City.

There is also the small matter of the warranty. A treatment you apply yourself is not covered by anyone.
