Roof Rejuvenation Frequent Questions

Roof rejuvenation is a scientifically tested process that restores the natural oils in asphalt shingles—oils that dry out over time due to UV exposure, oxidation, and Alberta’s extreme freeze-thaw cycles. When shingles lose these oils, they become brittle, start curling, and eventually crack.

Our treatment uses a 100% plant-based, USDA-certified oil that penetrates deep into each shingle. Once absorbed, it rehydrates and revitalizes the asphalt, restoring flexibility and extending the shingle’s protective lifespan. It’s a bit like moisturizing your roof—keeping it pliable and weather-resistant for years longer.

The process doesn’t coat the surface like paint or sealant; instead, it soaks into the shingle, restoring lost elasticity and improving resistance to wind, hail, and moisture. Roof rejuvenation is now a proven alternative to premature replacement, giving Alberta homeowners up to 10 extra years per spray—all for a fraction of the cost of a new roof.

Many rejuvenation products on the market rely on petroleum or synthetic oils that can damage shingles, harm vegetation, or wash off in the rain. Bright Green Roof uses a 100% biobased, non-toxic, Canadian-made formula designed specifically for Alberta’s harsh climate.

We’re the only roof preservation service that is:

‍ASTM-tested for flexibility, granule adhesion, and fire resistance.
‍
‍USDA-certified as a biobased product (100% active ingredients, no water dilution).
‍
‍Proudly Canadian-made and formulated for hail, snow, and UV extremes.
‍
‍Solar panel–friendly, with protective coverings and post-treatment cleaning included.

Our commitment to transparency and environmental responsibility sets us apart. Every roof we treat is backed by a 5-year transferable warranty and independent lab testing—so you’re not just taking our word for it.

Bright Green Roof rejuvenation works on most asphalt shingle roofs between 5 and 20 years old. It’s effective for architectural, 3-tab, and laminated shingles, provided they’re still intact and structurally sound.

We also offer specialty assessments for cedar shingles and solar panel–mounted roofs, with tailored approaches for each. The key factor is that the roof isn’t already leaking or rotting. During your inspection, our team checks for:

Cracking or curling shingles

Missing or loose sections

Evidence of water infiltration

Excessive granule loss

If your shingles are dry and showing signs of early aging—but not failing structurally—you’re likely a perfect candidate for rejuvenation.

Roof coatings and sealants sit on the surface and form a temporary barrier. They don’t address the root problem—the loss of essential oils inside the shingle. These coatings can flake, crack, or trap moisture, often doing more harm than good in Alberta’s fluctuating climate.

By contrast, Bright Green Roof’s rejuvenation penetrates the shingle, restoring flexibility from within. It doesn’t alter color permanently or affect shingle breathability. You can think of it as biological restoration, not cosmetic covering.

The result: a rejuvenated, not repainted, roof that continues to perform as designed—just stronger, more flexible, and longer-lasting.

Yes. Our product was formulated and tested for Canadian conditions, including hail, snow, freeze-thaw stress, and UV exposure. ASTM testing confirmed increased pliability and a 40% improvement in fire resistance, making it ideal for homes across Alberta—from Calgary to Grande Prairie.

Unlike coatings that can crack in cold weather, our treatment remains elastic, even in sub-zero temperatures. It’s absorbed into the shingle, so it won’t wash off or degrade when exposed to snow, sun, or summer storms.

Yes—both science and homeowners confirm it. Bright Green Roof’s treatment has undergone independent ASTM testing, the global benchmark for product safety and performance.

Results showed:

Increased flexibility and pliability of shingles

‍Stronger granule adhesion (reducing erosion)

‍40% improvement in fire resistance

‍Enhanced wind and hail durability

‍Beyond the lab, Alberta homeowners report visible improvements within days. Shingles regain color, feel supple again, and shed water more efficiently. In Calgary test cases, rejuvenated shingles even resisted nail cracking during later solar panel installations—something untreated roofs couldn’t match.

Each Bright Green Roof application extends your roof’s life by up to 10 years. For maximum longevity, we recommend reapplication every 5–7 years, depending on your roof’s exposure and local climate conditions.

Our 5-year transferable warranty guarantees your shingles won’t curl or crack during that period. If they do, we’ll re-treat your roof at no cost. With regular maintenance and inspections, homeowners often extend total roof life by 15 years or more, delaying costly replacements well into the future.

Our oil is both EPA and USDA compliant, meaning it meets North American standards for safety, environmental impact, and product purity. It’s also ASTM-tested for measurable performance improvements.

These tests confirm that our treatment:

Reduces degradation from heat and UV.

Strengthens shingle adhesion and structure.

Withstands hail and wind without cracking.

Improves fire safety performance.

This isn’t anecdotal—it’s backed by transparent, third-party data and years of field testing on Alberta roofs.

Most homeowners notice the difference immediately. Shingles regain a richer, darker tone as the oil penetrates and revitalizes the surface. More importantly, they become flexible again, preventing cracking and edge curling.

You’ll also see:

Improved granule adhesion (less loss in gutters).

More even coloration and water shedding.

Restored curb appeal and roof uniformity.

We provide before-and-after drone photos with every job, so you can see the rejuvenation for yourself. Within days, your roof not only looks newer but functions like it—flexible, sealed, and weather-ready.

Yes. Because our formula is non-toxic, shingle-safe, and ASTM-tested, it does not void existing manufacturer warranties. Many insurance providers view rejuvenation as proactive maintenance—similar to sealing a driveway or servicing a furnace.

Bright Green Roof also issues a certificate of treatment and 5 year warranty, proving your roof’s renewed condition. This documentation is especially valuable when selling your home or negotiating insurance renewals.

While pricing depends on roof size and pitch, most homeowners spend between $1,500 and $3,500—roughly 15–20% of what a roof replacement costs. Compare that to a typical $12,000–$18,000 new roof, and the savings are substantial.

Because we use satellite imagery and drone measurements, you’ll receive an accurate quote before any on-site work. Our goal is to extend your roof’s life, not replace it early—and our cost structure reflects that.

Absolutely. Roof rejuvenation delivers measurable performance at a fraction of replacement cost. It restores flexibility, improves resistance to hail and wind, and delays the massive environmental and financial waste of tearing off a roof prematurely.

It’s especially valuable if your shingles are 5 –15 years old and beginning to show dryness or fading—but not structural failure. By treating early, you save thousands and maintain your home’s value.

For most Alberta homes, rejuvenation offers a 400–600% return on investment compared to early replacement. A single spray can prevent or delay a $15,000–$20,000 expense while also improving curb appeal and resale value.

The savings multiply when you have solar panels, since removing and reinstalling them for roof replacement adds thousands more. Our treatment extends roof life beneath solar systems, eliminating that unnecessary cost.

Our rejuvenator is made from 100% biobased plant oils that mimic the natural asphalt compounds originally present in shingles. There are no petroleum solvents, synthetic additives, or fillers—just pure, active ingredients that restore what time takes away.

The formula is certified by the USDA BioPreferred Program and tested to ASTM standards, ensuring both safety and performance. It’s proudly produced in Canada, formulated for our climate, and designed to protect both homes and ecosystems.

Completely. Our product is non-toxic, biodegradable, and environmentally safe. It contains no harmful chemicals, VOCs, or synthetic residues. You don’t need to leave home or cover plants before we spray—though we still take care to protect gardens and furniture out of caution.

Once applied, the oil begins absorbing into the shingles immediately and poses zero risk to children, pets, or pollinators. Even runoff water is safe for lawns and flowerbeds.

Every roof we save prevents tons of asphalt waste from entering Canadian landfills. Shingle replacement contributes heavily to CO₂ emissions from manufacturing, transport, and disposal. By rejuvenating instead, you’re cutting waste, conserving resources, and extending your roof’s lifecycle by a decade or more.

Plus, Bright Green Roof plants one tree for every roof preserved, offsetting even more carbon. It’s protection that homeowners can feel genuinely good about—saving money while reducing environmental impact.

Yes! Besides from the thorough testing we did with the ASTM to prove the efficacy of our shingle preservation spray, Bright Green Roof's oil has also been extensively tested and certified by the USDA. We are 100% USDA Organic.

Alberta is one of the harshest environments in North America for asphalt shingles. Between scorching summer UV, heavy hail seasons, and extreme freeze-thaw cycles, shingles here lose their natural oils two to three times faster than in milder climates.

The expansion and contraction caused by temperature swings create micro-cracks in the asphalt. Over time, those cracks expand, allowing moisture to penetrate and granules to loosen. Add high-altitude UV exposure and dry prairie winds, and it’s a perfect storm for premature aging.

That’s why roof rejuvenation is especially beneficial in Alberta—it restores the oils and flexibility that harsh weather strips away, keeping shingles supple and weather-resistant for years longer. Many homeowners use rejuvenation as a preventative treatment before visible damage sets in, especially after hail-heavy seasons.

Yes. While no product can make a shingle completely hail-proof, rejuvenation significantly improves its ability to flex and absorb impact.

Testing under ASTM D3462 standards showed that treated shingles became more pliable and less likely to fracture when bent or struck. This pliability is key—dry shingles snap under pressure, while rejuvenated ones bend and rebound.

In Alberta, where golf-ball-sized hail isn’t unusual, that difference matters. A rejuvenated roof can often withstand moderate hailstorms that would otherwise shorten its lifespan or force costly insurance claims.

Excellent. Our formula was specifically engineered for Canadian climates. Once absorbed, it doesn’t freeze, crack, or lose effectiveness in sub-zero temperatures.

Unlike sealants or coatings that can become brittle in winter, Bright Green Roof’s rejuvenation remains elastic year-round, helping shingles expand and contract naturally during freeze-thaw cycles. It also improves water shedding, reducing the chance of ice dam formation along eaves.

That’s one reason Alberta homeowners who spray in summer notice fewer winter roofing issues—because their shingles stay flexible when cold weather hits.

Unfortunately no. Our spray is designed to be absorbed into the shingles over the granule layer, and then bind with those shingle's in the bitumen layer. The binding process is what makes our product so effective, but it requires the shingles to be at least 3 degrees. Which means we can only really service roofs some of the year - mid spring to the start of fall. Once its too cold, we have to shutdown! While we can measure, and inspect roofs, all year - our spray season is limited.  

We primarily specialize in asphalt shingle preservation, but we also offer assessments for cedar shake roofs. Cedar can sometimes benefit from our plant-based oil if the wood is weathered but not rotted.

Because cedar behaves differently from asphalt, we’ll evaluate moisture content and surface condition before recommending treatment. If rejuvenation isn’t suitable, we’ll advise alternative preservation methods.

Our process is simple, clean, and efficient:

‍Inspection & Qualification:
We inspect your roof for damage, dryness, and overall health to ensure it qualifies.

‍Measurement & Quote:
Using drone and satellite data, we provide an accurate estimate within 24 hours.

‍Preparation:
We protect your gardens, walkways, and solar panels, and perform minor tune-up repairs (re-caulking, replacing small sections).

‍Application:
The rejuvenation oil is sprayed evenly across your roof using low-pressure, precision equipment.

‍Absorption:
Within an hour, the formula begins to absorb into the shingles, restoring flexibility and adhesion.

‍Post-Check:
We complete a visual inspection and provide before-and-after photos so you can see the difference.

The entire process usually takes 2–4 hours, depending on roof size. There’s no mess, no strong odour, and no need to vacate your home.

We can usually tell with a quick inspection or drone scan. Ideal roofs:

Are 5–20 years old.

Have no active leaks or rot.

Show minor granule loss, fading, or brittleness.

If your shingles are brittle but still intact, rejuvenation will likely deliver excellent results. Roofs with structural damage, leaks, or missing sections may need minor repair before treatment.

The oil penetrates quickly—typically within 30–60 minutes. You can safely walk on the roof or let rain fall shortly afterward. Any remaining surface sheen disappears within a few days as absorption completes.

Every eligible roof comes with a 5-year transferable warranty. It covers curling, cracking, and loss of shingle flexibility. If your shingles don’t maintain elasticity during that period, we’ll re-treat your roof free of charge.

This warranty transfers to the next homeowner if you sell your property, making it a selling feature and proof of proper roof maintenance.

Roof rejuvenation is designed for prevention, not repair. If leaks or major damage are present, we’ll identify and address those first through basic roof tune-up services. Once the roof is watertight, rejuvenation can safely restore its condition and prevent further deterioration.

That’s a fair question—and it’s exactly why we rely on science and certification instead of marketing hype.

Our product is ASTM-tested, USDA-certified, and EPA-compliant, and the results are publicly documented. Unlike unverified “miracle sprays,” Bright Green Roof is backed by independent data proving it increases flexibility, hail resistance, and fire safety.

We’re not coating your shingles—we’re replenishing them with the same type of natural oils they originally contained. Homeowners across Alberta have seen and felt the difference, often within days.

No. The rejuvenator penetrates into the asphalt layer of each shingle rather than sitting on the surface. Once absorbed, it chemically bonds to the shingle material and becomes part of it.

It’s not a coating—it’s an internal restoration process. In fact, one of our ASTM tests included simulated rainfall and water abrasion, and treated shingles maintained their improved pliability and adhesion even after extended exposure.

Roof rejuvenation is relatively new in Canada but has been used in the U.S. for over a decade. As awareness spreads, more homeowners are realizing they don’t need to replace an entire roof just because it’s dry or faded.

The industry’s recent growth in Alberta mirrors what happened with spray-foam insulation and solar panels—technologies once niche, now mainstream. The difference is that rejuvenation has independent testing, government certification, and thousands of successful applications to prove its value.

No. Because the formula is non-toxic, petroleum-free, and shingle-safe, it does not void manufacturer warranties. In fact, rejuvenation often helps homeowners preserve warranty eligibility by maintaining the roof’s performance and flexibility longer than average wear would allow.

Bright Green Roof Alberta is part of the national Bright Green Roof network, with multiple certified dealers across the province. We’re locally owned, proudly Canadian, and fully committed to long-term service and support.

We stand behind our 5-year warranty—and our presence in Alberta continues to grow each year as more homeowners experience the results firsthand.

You can request a quote online or through your local BGR dealer. We use satellite and drone technology to measure your roof remotely, meaning you don’t need to be home. Once we confirm roof size and age, you’ll receive a detailed estimate and inspection plan.

We’ll ask for:

Your address (for measurement and satellite imagery).

Approximate roof age and material type.

Any known issues (leaks, missing shingles, discoloration).

This helps us determine eligibility and prepare accurate pricing before we visit, and perform a roof inspection! We want to make sure your roof is in good condition before we spray.

Most homeowners book between April and October, but we can provide quotes year round. Once approved, we can typically perform your shingle preservation service within 1–2 weeks, weather permitting.

Absolutely! We offer a referral reward program—when you recommend us and your friend books a treatment, you both receive $100. It’s our way of saying thank you for spreading the word about sustainable roofing in Alberta.

We serve Albertans across the province, but you can get more information by speaking to your closest dealer. Depending on your location there may be a travel fee or additional costs - but these will be included in your quote ahead of time - there are no hidden costs with Bright Green Roof.

Yes — absolutely. Bright Green Roof’s rejuvenation process is 100% solar-panel safe and specifically adapted for homes with PV systems. We regularly work with both residential and commercial solar arrays across Alberta.

Before spraying, our technicians carefully cover each panel with protective tarps or sheeting to prevent any overspray. Once the treatment is complete, we clean the panels afterward to remove dust or residue, ensuring maximum energy production.

Because the rejuvenation oil penetrates into the shingles instead of sitting on the surface, it doesn’t interfere with solar mounts, flashing, or hardware. There’s no need to uninstall or disconnect your system — everything stays intact and functional during the process.

Solar systems last 25–30 years — much longer than most asphalt roofs. That means homeowners often face an expensive problem: the roof wears out before the panels do.

Replacing a roof under solar panels requires removing and reinstalling the entire system, which can cost $2,000–$6,000 extra on top of the replacement itself. By rejuvenating the shingles every 5–7 years, you extend your roof’s life to match your solar investment, avoiding that major disruption and expense.

Many Alberta homeowners install solar only to discover their roof is 10–12 years old — a perfect candidate for rejuvenation. Bright Green Roof helps ensure your roof lasts as long as your solar system does.

Yes. Our formula is non-conductive, non-corrosive, and 100% biodegradable. It won’t damage electrical conduit, mounts, or flashing seals. It also doesn’t emit fumes or residues that could affect panel coatings.

We use low-pressure application equipment to keep spray controlled and precise. After the treatment, panels are hand-wiped and inspected before the job is signed off. Your solar output and efficiency remain unaffected — often even improved thanks to the post-treatment cleaning.

That’s actually the best time to do it. Spraying before installation ensures your roof is in peak condition for panel mounting and helps prevent premature aging beneath the array (where sun exposure is reduced, but moisture and heat still accumulate).

We recommend rejuvenating your roof within a year before solar installation. That way, you begin your solar journey with a roof protected against the elements and strong enough to support 25+ years of clean energy.

Yes. Most reputable solar contractors appreciate rejuvenation because it prevents callbacks related to roof deterioration. Our team even collaborates with solar installers across Alberta to coordinate timing, especially for pre-install treatments.

We provide full documentation and product data sheets for their records — including USDA and ASTM certifications — so they know your roof has been treated with a verified, eco-safe product.

If your shingles are nearing the end of life but you’re not ready for replacement, rejuvenation is your ideal bridge solution. It extends the usable lifespan of your existing shingles, giving you 5–10 more years before any major teardown.

This delay means you can better align future roof replacement with solar panel upgrades or warranty cycles — saving thousands and avoiding two separate service calls.

Completely. Bright Green Roof shares the same philosophy as solar energy — sustainability, longevity, and eco-responsibility. Our formula is USDA-certified biobased, made from plant oils instead of petroleum, and safe for both rooftop systems and surrounding environments.

When you rejuvenate instead of replace, you prevent up to 3,000 kilos of shingle waste from entering Alberta landfills — while your solar panels continue producing clean energy overhead. It’s one of the most environmentally responsible home improvements you can make.
