Does Roof Rejuvenation Really Work?

The question behind the question

Most homeowners asking 'does it work' are really asking two things: will it do something measurable, and is my roof the kind of roof where it matters.

The second question is the one that decides the outcome. A treatment aimed at shingle flexibility does nothing for a roof whose deck is soft or whose flashing is leaking.

How to judge a rejuvenation pitch

Ask any company offering this treatment these questions:

• Did you get on the roof, or did you quote from the driveway?
• What specifically about my shingles makes them a candidate?
• What did you find at the flashing, valleys and penetrations?
• What documentation supports the performance claims you are making?
• Under what conditions would you tell me not to do this?

What Roof Vital publishes and what it doesn't

We do not publish a specific number of added years, a guaranteed savings figure, or a claim that the treatment restores shingles to new condition. Where a manufacturer supplies documented performance data and warranty terms, we will publish those and cite them.
