How Does Roof Maxx Work?
Asphalt shingles age because the oils in the asphalt evaporate over time. Roof Maxx is a soybean-oil-based bio-oil that penetrates the asphalt matrix and replenishes those lost oils, restoring shingle flexibility and water-shedding capability. Plant-based. Pet-safe once dry. Authorized-dealer applied by trained technicians. Same-day install, no tear-off, no dumpster.

Why Aged Asphalt Shingles Fail
An asphalt shingle is a fiberglass mat soaked in asphalt, with mineral granules pressed on top. The asphalt is what makes the shingle flexible, waterproof, and bonded to the granules. Over years of UV exposure and thermal cycling, the volatile oils in the asphalt evaporate. The shingle becomes brittle, the granule bond weakens, and the shingle starts shedding granules and losing flexibility. That’s what age looks like on a roof.
Roof Maxx is a soybean-oil-based bio-oil engineered to penetrate the asphalt matrix and replace the lost oils. The shingle regains flexibility, the granule bond is strengthened, and the shingle returns to a serviceable state. The bio-oil is USDA-Certified BioPreferred and pet-safe once dry.
How Roof Maxx Restores a Shingle
Soybean-oil bio-oil penetrates the asphalt matrix and replaces the lost volatile oils. Here’s what’s happening at each stage.
01 What ages a shingle
UV exposure and thermal cycling boil off the volatile oils that keep asphalt flexible. Without them, the shingle becomes brittle, the granule bond loosens, and shedding starts.
02 The soybean bio-oil
100% soybean-derived bio-oil, USDA-Certified BioPreferred. Plant-based, biodegradable, pet-safe once dry. Not a paint, not a coating, not a sealer.
03 Penetration
The bio-oil soaks into the asphalt matrix at the molecular level, replacing the lost oils. You can see the visible color restoration immediately after application.
04 Flexibility restored
Independent testing shows treated shingles regain measurable flexibility. The granule bond strengthens. The water-shedding ability returns.
05 5 years of life
Each application adds approximately 5 years of usable life. Manufacturer-backed 5-year transferable warranty registered in your name.
06 Re-treatable
A roof can be re-treated 2 to 3 times over its remaining service life. Treat at year 12, re-treat at 17, again at 22. Reach year 27 in serviceable condition.
What to Expect On Application Day
Total disruption is half a day. No tear-off, no dumpster, no crew of 8 on your roof for a full day. Here’s the sequence.
| Stage | What Happens | How Long |
|---|---|---|
| Pre-arrival | Move cars off the driveway. Bring pets inside. We coordinate around weather, dry forecast required. | Day before |
| Surface prep | Technicians arrive, clear debris from the roof, check flashing, stage the spray equipment. Cover delicate plantings below the eaves. | 15 to 30 min |
| Spray application | Low-pressure backpack sprayers, calibrated for the correct rate per square. Two-person trained crew walks the roof methodically. No skipped sections. | 90 min to 3 hrs |
| Cleanup | All equipment packed. Plant covers removed. Final walk-around. We document the work with photos. | 15 to 30 min |
| Dry time | Product dries fully in 1 to 2 hours. Pet-safe and people-safe once dry. No odor. | 1 to 2 hrs |
| Warranty filing | 5-year transferable warranty registered with Roof Maxx Inc. in your name. Filed before we leave. | Same day |
Spray-Day Approved
Why the Application Spec Matters
Roof Maxx isn’t sprayed at full pressure or poured on like a coating. It is misted at a low pressure, calibrated rate. Coverage uniformity is the entire game. If a technician misses 5% of the field, 5% of your shingles don’t get rejuvenated, and that part of your roof keeps aging on schedule.
What our trained applicators do that day-labor crews don’t
- Calibrated spray rate. Each backpack sprayer is calibrated to deliver the manufacturer-spec amount per square foot. Too much wastes product, too little fails the treatment.
- Methodical roof walk pattern. Crews work in overlapping passes so no shingle is missed at panel edges. The pattern is the same every roof, trained on the Roof Maxx authorized-dealer specification.
- Edge and valley detail. Eaves, valleys, and flashing junctions get the same coverage as the field, applied carefully so the bio-oil reaches the asphalt under the granule layer.
- Dry-day weather check. Rain within 4 hours of application washes the bio-oil off before it penetrates. We watch the 72-hour radar before locking the date and reschedule for free if forecast turns.
- Photo documentation. Before-and-after photos of the roof, plus warranty paperwork filed with Roof Maxx Inc. in your name before we leave.

The Roof Maxx Lifecycle, Year by Year
Each application adds approximately 5 years. Re-treat 2 to 3 times for a full 15-year extension on your asphalt shingle roof’s serviceable life.
Day 1: Application
Bio-oil applied. Visible color restoration immediately. Roof flexibility starts returning within days.
Year 1-5: Full coverage
5-year transferable warranty in force. Restored shingles continue to shed water and resist thermal stress like new.
Year 5-6: Re-evaluate
HAAG-Certified re-inspection. If shingles still structurally sound, a second application extends life another 5 years.
Year 10-11: Third treatment
Optional third application for roofs still in good shape. Pushes serviceable life to ~year 22 to 27 total.
Year 22+: Replacement
When mat failure finally arrives, we replace with Owens Corning Platinum Preferred 50-year warranty. Same contractor, full lifecycle.

What VA and MD Homeowners Say
“Two technicians, 2.5 hours, completely covered every inch of roof with the spray. They walked me through the bio-oil chemistry first so I understood what was happening. Pet-safe meant my dogs didn’t have to leave. Done by lunch.”
Marcus G., Reston VA
“The color difference was visible immediately. Our shingles had gone gray-tan from the sun; after Roof Maxx they were back to the dark gray we picked when the roof was new. Five years on, they’re still flexible and shedding water like new.”
Karen B., Bowie MD
“DreamHome explained that Roof Maxx isn’t a coating, it’s a treatment that soaks in. That answered my biggest concern. I’d seen ‘roof coating’ scams in the news; this is different. USDA-Certified product, manufacturer warranty, authorized dealer.”
Thomas H., Loudoun County VA

Frequently Asked Questions
How does Roof Maxx work?
Asphalt shingles age because the petroleum-based oils in the asphalt evaporate over time, making the shingle brittle. Roof Maxx is a soybean-oil-based bio-oil that is sprayed onto the shingle. The bio-oil penetrates the asphalt matrix and replenishes the lost oils, restoring shingle flexibility and water-shedding capability.
Is Roof Maxx safe for landscaping and pets?
Yes. Roof Maxx is plant-based (USDA-Certified BioPreferred) and is safe for landscaping, pets, and people once dry, typically 1 to 2 hours after application. Plants and pets can be inside during application but are kept clear of the application path during spraying.
How long does the application take?
Most single-family residential applications are 90 minutes to 3 hours of on-site work. The product dries in 1 to 2 hours. Total disruption is typically a half-day. No tear-off, no dumpster, no crew of 8 on your roof for a day.
How is Roof Maxx applied?
The treatment is sprayed onto the shingles with low-pressure backpack spray equipment, calibrated to deliver the correct application rate per square. The technicians are trained on Roof Maxx’s authorized-dealer specification: application rate, surface prep, edge work.
How many times can a roof be treated?
A roof can typically be re-treated 2 to 3 times over its remaining life. Each treatment adds approximately 5 years. A roof treated at year 12 and re-treated at year 17 can reach year 22 in serviceable condition.
What is USDA-Certified BioPreferred?
USDA BioPreferred is a federal certification that identifies products made primarily from renewable agricultural materials (in Roof Maxx’s case, soybean oil). Certification means the product meets minimum bio-based content standards and is preferred for federal procurement. It is the same agency that runs USDA Organic, but the BioPreferred program is specifically for non-food industrial products.
