OnyaRoof Hawaii restores aging asphalt shingles for up to 80% less than replacement — adding up to 15 years of life to the roof you already have. Done in hours, not days.
Modern asphalt shingles dry out years before they wear out. As the natural oils evaporate, shingles get brittle, crack, shed granules — and roofers tell you the only fix is a $20,000+ replacement. It isn't.
A full replacement means tearing off thousands of pounds of shingles, days of noise, a dumpster in your driveway — and a $20,000+ check. Rejuvenation skips all of it.
James inspects your shingles, granule loss, and flashing — honestly tells you if rejuvenation fits (and if it doesn't).
We secure loose shingles, re-seal flashings, and fix nail pops before treatment — included.
A plant-based bio-oil spray penetrates the shingles, restoring flexibility and waterproofing.
Every treatment carries a 5-year transferable warranty. Repeat every 5 years for up to 15 extra years.
The difference one treatment makes.
“They saved us over $15,000 compared to the replacement quote we got. The whole treatment was done in one afternoon and our roof looks brand new.”
“James walked the entire roof, fixed two loose flashings before the treatment, and explained everything. Honest company — didn't try to sell us a new roof we didn't need.”
“Our insurance company flagged our roof at renewal. After the rejuvenation treatment and tune-up we passed inspection with no issues.”
Within roughly 100 miles of Honolulu:
Yes. The treatment is a plant-based bio-oil that penetrates aging asphalt shingles and restores the flexibility and waterproofing oils they lose over time — independently lab-tested and used on hundreds of thousands of roofs across the U.S. Each treatment adds up to 5 years of life, repeatable up to 3 times for 15 extra years.
A typical roof replacement in Honolulu runs $20,000–$25,000+. Rejuvenation costs a fraction of that — usually around 20% of replacement cost — and is done in hours, not days.
Insurance companies are increasingly dropping or surcharging homes with aging roofs. A documented tune-up and rejuvenation treatment can help your roof pass inspection and extend its insurable life.
Yes — the treatment is a USDA-certified bio-based product, 100% safe for people, pets, and landscaping.
We do a free assessment: James inspects your shingles, checks granule loss and flexibility, and tells you honestly whether rejuvenation makes sense — or whether you genuinely need a replacement. No cost, no obligation.
We serve Honolulu and everywhere within about 100 miles, including Kailua, Kaneohe, Pearl City, Aiea, Mililani, Kapolei, Ewa Beach and Honolulu.
Not every roof is a candidate — that's exactly why the assessment is free. James will tell you straight whether rejuvenation makes sense for your home.
