A professional asphalt shingle rejuvenation service that restores dried-out shingles from the inside out. Extend your roof's life 5–15 years — without the cost and disruption of replacement.
Asphalt shingle rejuvenation — also called shingle rejuvenation, shingle rejuvenation service, or asphalt shingle coating rejuvenation — is a bio-oil treatment that restores what your shingles lose over time.
Asphalt shingles contain petroleum-based oils that give them flexibility, waterproofing ability, and UV resistance. Over time — accelerated by Ontario's freeze-thaw cycles, hot summers, and UV radiation — those oils evaporate. The shingles become dry and brittle. They crack more easily, shed granules faster, and fail years before their rated lifespan.
This is why a 30-year shingle often needs replacing at 15–18 years. It's not that the shingle is structurally gone — it's that it's been starved of the oils that keep it performing.
A certified contractor sprays a bio-oil solution evenly across your asphalt shingles. The treatment penetrates the surface and replenishes the oils that have been lost — restoring flexibility, reactivating the waterproofing, and improving UV resistance. Think of it as deeply moisturising dried-out shingles rather than replacing them.
Shingle rejuvenation doesn't just coat the surface — it penetrates into the asphalt matrix to restore properties from the inside out. This is what makes it fundamentally different from a roof sealant or coating.
Most asphalt shingle roofs between 7 and 20 years old are good candidates, provided the shingles are still structurally intact — no missing shingles, active leaks, or structural damage. A free on-site assessment confirms eligibility in about 30 minutes.
Assessment. A specialist inspects your shingles for age, brittleness, granule loss, and structural integrity to confirm the roof qualifies.
Surface preparation. If biological growth is present, a soft wash clean is recommended first to ensure full penetration of the treatment.
Bio-oil application. The rejuvenation solution is sprayed evenly across all shingle surfaces using low-pressure equipment. The process takes 2–4 hours for a typical home.
Absorption. The bio-oil penetrates the asphalt matrix over 24–48 hours, restoring flexibility and waterproofing from within.
Documentation. You receive written certification of the treatment — useful for insurance renewals and future property sales.
Asphalt shingle rejuvenation goes by several names depending on who you ask — shingle rejuvenation, shingle rejuvenation service, asphalt shingle roof rejuvenation, asphalt shingle coating rejuvenation, or simply roof rejuvenation spray. They all refer to the same treatment: a bio-oil solution applied to restore the properties of aged asphalt shingles. If you've been searching for any of these terms in the Brantford or Hamilton area, you've found the right service.
For a qualifying asphalt shingle roof, rejuvenation is one of the best-value home maintenance decisions you can make.
Asphalt shingle rejuvenation costs $500–$2,000 for a typical Ontario home. A new roof costs $12,000–$22,000. The math rarely favours replacement when shingles still have structural life in them.
By restoring the oils your shingles have lost, rejuvenation extends their functional life significantly — delaying the replacement decision by years and putting that money back in your pocket.
A documented shingle rejuvenation treatment is a positive for home inspectors and buyers. It demonstrates the roof has been actively maintained and extends its certified lifespan.
Ontario insurers are increasingly scrutinising roof age. A rejuvenation treatment with written documentation shows your insurer the roof is maintained — helpful at renewal time.
No tear-off, no dumpster, no days of noise. The treatment is sprayed on your existing shingles and is typically complete within a morning. You don't need to leave the house.
Roof replacement generates thousands of kilograms of shingle waste per home. Rejuvenation extends what's already there — no landfill impact, no manufacturing of new materials.
Cost depends on roof size, pitch, and condition. Here are typical ranges for homes in the Brantford–Hamilton area.
These are typical ranges based on local market pricing. The only way to get an accurate quote for your specific home is a free on-site assessment — pitch, access, and shingle condition all affect the final price. Add $300–$700 if a soft wash clean is needed first.
Rejuvenation works best on shingles that are dried out but still structurally sound. Here's how to assess your own roof from the ground.
