The problem

A replacement is a demolition project. It may not be necessary.

Standard roof solutions give you two options: tear the whole thing off, or patch the one spot you can see. Neither answers a roof that is sound but drying out.

Rejuvenation does not fix a roof that is leaking or failing. When that is what the assessment finds, replacement is the honest answer and we will say so. Patch repairs only fix the one spot that is showing; the rest of the roof is left exactly as it was.

Reviews

What homeowners say.

Unedited words from Dr. Armor customers.

Awesome company, very nice guys. Eric is quick to respond and very honest. I am very pleased with the result, roof looks new.
Denis Farley9 months ago
I researched the product (GoNano Revive), and it's good technology. If my 16 year old shingles last another 10 years with this treatment, I'll be extremely happy.

What the product does

Five surface problems. One treatment.

GoNano nanotechnology puts back what asphalt and concrete lose to sun and weather, so the surface keeps working long after it started drying out.

Where it applies

Asphalt shingle roofs

Four treatments, matched to the condition of the roof: Fortify and Fortify Elite for sound roofs, Revive for an aging one, Boost for a roof near the end of its life.

See the treatment range
Concrete

Driveways, patios and walkways with Concrete Saver, for the same reason: protection inside the surface, not on it.

Concrete Saver

See the difference

Water sits on top. It doesn’t soak in.

Two shingles and one drop of rain. On the treated surface the water stays where it lands. On the untreated one it goes into the material.

Untreated: water spreads across the shingle and sits in the surface.

Illustration of how the surface behaves. It is not a measured result.

Treatment options

Matched to the condition of your roof, not to a price list.

Condition decides which one fits. Each treatment is a different build, not a different amount of the same thing.

NuRoof · UV shield

Fortify

A UV shield for a roof that is still holding up.

One coat of nanoparticle protection that slows the sun’s breakdown of the shingle. The everyday pick for good or fair roofs.

  • Slows UV breakdown of the asphalt
  • Up to 15 years of coverage

Not sure which treatment fits?

Asphalt shingle roofs are eligible after the assessment; metal roofs are not. The assessment scores the roof’s condition and confirms the treatment and warranty that follow from it.

The product in brief

Not a coating. A treatment for the material itself.

GoNano is a nanotechnology treatment for surfaces that are still sound but have dried out. It moves into the material and replaces the oils the sun and weather have pulled out, so the surface stops soaking up water and starts shedding it again.

Nothing is torn off, covered over or replaced. One visit, about two hours, and the surface you already own keeps doing its job for years longer.
