How They Stack Up

A straightforward comparison so you can make an informed decision.

Full Roof Replacement Roof Rejuvenate East Bay
Typical Cost $20,000 – $35,000+ ~$3,000
Time to Complete 3 – 7 days Under 2 hours
Disruption Dumpster, crew, noise for days None — you don’t even need to be home

Required When Structural failure, major damage Shingles are aging but granules intact
Insurance Impact May be required by insurer Certification may satisfy insurer requirements
Environmental Impact Significant — tear-off waste 96% plant-based, USDA Certified Biobased

  • ✓Oil loss is the #1 cause of premature shingle failure
  • ✓Structural integrity often remains long after oils evaporate
  • ✓Rejuvenation restores oils at the molecular level
  • ✓3rd-party testing confirms 53% better granule adhesion
The Science

Why Roofs Fail Before They Should

Asphalt shingles are engineered with natural oils that keep them flexible, granules bonded, and resistant to cracking. Over time — typically 10 to 15 years — those oils evaporate due to UV exposure and heat cycling.

When that happens, shingles crack, curl, and shed granules. Most contractors see this and quote a full replacement. But in most cases the shingle substrate is still sound — it just needs its oils restored, not a full tear-off.

The Treatment

What Rejuvenation Actually Does

Our 96% plant-based, USDA Certified Biobased formula soaks deep into each shingle, replacing the oils that have been lost to time and sun. This isn’t a coating or a sealant — it works from the inside out.

  • ✓Restores shingle flexibility — 66.7% improvement in lab testing
  • ✓Improves granule adhesion — 53% better retention
  • ✓Inhibits moss and algae growth
  • ✓Reverses UV discoloration — shingles darken to near-new appearance
  • ✓Done in under 2 hours — manufactured by Colorbiotics, lab-tested by PRI

Our Honest Take

When You Actually Do Need a New Roof

Rejuvenation isn’t right for every roof. We assess every home during a free inspection and will tell you clearly if yours needs replacement instead. Here’s what disqualifies a roof from treatment:

Roof Replacement Is the Right Call When:

  • →Shingles have severe structural damage or are actively failing
  • →Granules are almost entirely gone — exposing the asphalt mat
  • →Multiple shingles are missing or lifted
  • →There is active water intrusion or decking damage underneath
  • →The roof is well past its designed service life with no recoverable shingles

If any of these apply to your roof, we’ll tell you during the free inspection — before any commitment is made. We don’t treat roofs that won’t benefit. That’s the job.

Common Questions

Rejuvenation vs. Replacement FAQ

More questions? Visit our full FAQ page.

Is roof rejuvenation better than roof replacement?
+
For most roofs with intact granules and no structural failure, rejuvenation is significantly better value — costing roughly 10% of replacement while extending shingle life by up to 15 years. Replacement is only necessary when the roof has genuinely failed.
How do I know if my roof can be rejuvenated instead of replaced?
+
The key indicator is whether your shingles still have granules. If they do, and there’s no structural damage or active water intrusion, your roof is almost certainly a candidate. The only way to know for sure is a free inspection — we assess every roof honestly and tell you upfront.
How much cheaper is rejuvenation than replacement?
+
Roof rejuvenation costs approximately $3,000 for a standard 2,000 sq ft roof in Contra Costa County, compared to $20,000–$35,000+ for a full replacement — a savings of 85–90%.
My roofer told me I need a full replacement. Should I get a second opinion?
+
Yes — especially if your shingles still have granules and aren’t structurally compromised. Many homeowners who are told they need a new roof actually have dry, brittle shingles that respond well to rejuvenation. Our free inspection is a no-obligation second opinion.
Can roof rejuvenation help with insurance requirements?
+
Possibly. Some homeowners have used the treatment certification and 5-year warranty to satisfy their insurer’s requirements without a full replacement. We provide documentation you can share with your carrier. Results vary by insurer and policy.
