No. With a high solids content and under 50 g/L of solvents, Liqua-Roof is an ultra-low VOC, safe, non-toxic product.

FAQ | Liqua-Roof™

Q: Does Liqua-Roof protect against hail?

Yes! Liqua-Roof enhances impact resistance by over 300% compared to uncoated shingles by layering granules and proprietary solids bonded with our advanced resin formula.

Q: Will Liqua-Roof prevent leaks and waterproof my roof?

Liqua-Roof forms a continuous, hydrophobic, water-resistant film. While not warrantied for waterproofing, we offer an optional waterproofing basecoat for higher-risk areas.

Q: Will granules begin shedding like regular shingles?

Granule shedding may occur slowly. Our granules are glued on for superior adhesion. In ASTM 4977 testing, our coating showed 90% less granule loss than uncoated shingles.

Q: Does Liqua-Roof reflect heat and can it keep my home cool?

It can—by using solar reflective roofing granules, which are available at a premium cost.

Q: Does Liqua-Roof protect against moss and algae?

Yes! Liqua-Roof includes algaecides and fungicides, and its smooth finish helps prevent moss and algae growth.

Q: Is Liqua-Roof the same as rejuvenating your roof with an oil?

No. While oil treatments hydrate shingles, they don’t restore granules. Liqua-Roof re-granulates and reinforces shingles with a durable, long-lasting surface layer—stronger than the original.

Roof repair & resurfacing

Does Liqua-Roof breathe?

Yes! Standard asphalt shingles have a perm rating of 0.65, while our system rates at 5.64 perms—over eight times more breathable. This means it won’t trap moisture or act as a vapor barrier over existing shingles.

Will Liqua-Roof fade over time?

No—Liqua-Roof is not a paint. Its color comes from pigmented granules, not a surface coating. Like those used in new shingles, these granules are naturally fade-resistant. For added protection, each granule is encapsulated in a UV-resistant resin, further shielding them from sun exposure.

Will Liqua-Roof come off over time?

No. Liqua-Roof exceeds ASTM D6803 standards for roof coating adhesion by over 200%—bonding at more than 5 pounds, well above the required minimum. But just for added peace of mind for our customers, all projects are backed with a 15-year warranty against premature wear.

Does Liqua-Roof protect against wind?

Yes. Liqua-Roof seals shingles together, forming a continuous roof overlay, and as a result, an aerodynamic surface that resists wind uplift. This added layer effectively glues down the shingles, enhancing wind resistance. In testing, Liqua-Roof withstood wind tunnel conditions at 110 mph for over 5 minutes with no delamination.

Does Liqua-Roof protect against hail?

Yes! Liqua-Roof significantly improves impact resistance by adding a new granule layer bonded with a proprietary resin. The system can increase impact resistance by over 300% compared to untreated shingles. Liqua-Roof resurfaced shingles have also been independently tested to UL 2218 Class 4, the highest hail impact resistance classification.

Will Liqua-Roof prevent leaks and waterproof my roof?

While we don’t warranty waterproofing, Liqua-Roof forms a continuous, hydrophobic, and water-resistant film across your roof. For higher-risk areas, we offer an optional waterproofing basecoat for additional protection.

Will granules begin shedding like regular shingles?

Granule shedding may occur over time but at a significantly slower rate. Unlike new shingles, where granules are simply “tossed” onto hot asphalt during the manufacturing process, we physically glue the granules onto the shingles for superior adhesion. In ASTM 4977 testing, our coating showed 90% less granule loss compared to uncoated shingles, ensuring long-lasting protection.

Does Liqua-Roof reflect heat and can it keep my home cool?

It can— by using solar reflective roofing granules in the mixture, which we can do but comes at a premium cost compared to standard granules.

Does Liqua-Roof protect against moss and algae?

Yes! Liqua-Roof contains built-in algaecides and fungicides to help prevent the growth of moss and algae. Additionally, its smoother, more washable finish makes it harder for organic matter to take hold compared to traditional asphalt shingles.

Is Liqua-Roof an alternative to roof replacement?

Absolutely! Liqua-Roof delivers the benefits of a new roof—protection, appearance, and durability—at a fraction of the cost, time, and without all the mess and disruption of a full replacement.

How is it possible to claim that Liqua-Roof is stronger than new shingles?

It’s all about the granules. Asphalt shingles are composed of multiple layers—fiberglass for structure, asphalt for flexibility and waterproofing, and a topmost layer of granules that provides the true protection against sun, wind, and water. When those granules erode over time, your roof begins to break down. The asphalt underneath gets exposed, leading to curling, cracking, and eventual failure.

What makes Liqua-Roof unlike any roof treatment or coating on the market is that we don’t just preserve what’s left—we rebuild it. Our resurfacing system adds a new, high-build granule layer directly onto your existing shingles, increasing their protective barrier beyond even what you’d get with brand-new shingles—including those rated Class-4 for impact resistance. That’s what makes Liqua-Roof a true upgrade, not just maintenance.

How is Liqua-Roof different from installing new shingles over existing ones?

Unlike layering new shingles, our treatment is significantly more cost-effective and dramatically lighter. Traditional shingles are heavy due to their asphalt and multiple layers—materials our process eliminates. Liqua-Roof coated shingles weigh less than 20% of conventional new shingles. This reduced weight helps preserve your roof's structural integrity and allows it to continue breathing properly, unlike applying shingles over existing shingles.

Why can't shingle manufacturers just do what Liqua-Roof does?

Shingle manufacturers are in the business of making shingles at scale with an expected life expectancy based on the shingle rating. To bond granules the way GranuLock does, they'd need to fundamentally re-engineer their manufacturing process - different adhesives, different application methods, different curing. That's a massive shift and capital investment and even if they did it, the cost would get passed down and make shingles more expensive across the board. Likely cost prohibitive - and the extra granule weight, while negligible for the roof structure, would make installation significantly more cumbersome. But that extra granule mass is exactly what makes Liqua-Roof perform the way it does.

By adding a new layer of granules on top of the existing ones, you're getting more coverage than any factory could apply in a single manufacturing pass. That's what drives the added benefits: better UV protection, better impact resistance, better weatherproofing. A factory is starting from scratch with a clean substrate. We're building on top of what's already there and adding to it. You can't replicate that outcome on an assembly line.

And fundamentally, the factory can't solve a field problem. By the time granule loss is an issue, that roof has been weathering for 10, 15, 20 years. GranuLock is applied to a roof in its current condition to extend its life. That's the whole point - and it's not something any manufacturer engineered a solution for. It's the gap Liqua-Roof was built to fill.

How does Liqua-Roof stack up to nano-particle sealers?

Compared to basic oil rejuvenators, nanoparticle or advanced resin-based formulas penetrate a little deeper into the shingle, so they are slightly less likely to run off and therefore, should last a little longer. While these treatments replenish lost oils to delay cracking, even they fall short of addressing the root issue: granule loss. In the end, they’re still buying you time, not solving the problem.

Liqua-Roof, on the other hand, actively replaces and reinforces that protective layer by bonding additional granules to the roof’s surface. The result? A fortified roof that doesn’t just delay replacement—it makes it unnecessary. Read more about the difference between Liqua-Roof and other roof treatments.

Can oil rejuvenation improve impact resistance like Liqua-Roof?

No. Oil rejuvenators soften shingles but do not add granules or strengthen the surface. Liqua-Roof increases impact resistance up to 3× stronger than new shingles by adding a reinforced granule layer bonded with our proprietary resin.

How does Liqua-Roof compare to roof paints or coatings?

Roof paints can extend roof life but don’t address granule loss once it has occurred. Liqua-Roof not only protects and prolongs your roof’s lifespan but also adds a durable layer of multi-colored granules, providing long-lasting protection and a natural, dimensional appearance—just like brand-new shingles. In contrast, roof paints typically leave a flat, one-dimensional finish that looks noticeably repainted.

Is Liqua-Roof the same as rejuvenating your roof with an oil?

Not quite. Our treatment rejuvenates and reinforces your roof, but with a fundamentally different approach. Traditional oil-based rejuvenation slows deterioration by using oil to rehydrate the asphalt in shingles. However, since it doesn't replace the lost protective granules, the asphalt remains exposed to UV rays and continues to degrade—requiring reapplication every few years.

We restore and fortify shingles by literally re-granuling them. We apply a liquid-bonded layer of new granules that replicates your shingles’ original surface and restores protection—stronger than the original. Unlike oil treatments, this new protective layer does not require repeated applications and is engineered to last as long—or longer—than a new roof.

Sound bold? It’s not. We're physically adhering granules to the shingle surface—unlike factory shingles where granules are embedded during manufacturing. This ensures superior retention and long-term protection!

How does Liqua-Roof compare to shingle sealers and rejuvenators?

Shingle sealers and rejuvenators soften asphalt to prevent cracking but don’t replace lost granules or reinforce shingles with a new protective layer. While they offer some short-term protection, these solutions ultimately delay—but don’t eliminate—the need for a roof replacement. Liqua-Roof provides lasting protection by restoring and reinforcing your roof with a durable granule layer.

Does Liqua-Roof last longer than oil rejuvenation treatments?

Yes. Oil rejuvenators temporarily restore oils in shingles but require reapplication every few years. Liqua-Roof rebuilds the protective granulated layer with a high-build system, delivering long-term durability and a 15-year warranty and no maintenance cycles.

Is oil rejuvenation effective for roofs with granule loss?

Only partially. Oil treatments cannot replace lost granules and don’t stop granule shedding. And it’s important to note that most shingle and roof rejuvenators require no more than approximately 30% granule loss to be effective. If your shingles have experienced higher granule loss, your roof is most likely not a candidate for these maintenance solutions. Liqua-Roof is engineered specifically to restore lost granules, rebuild volume, and lock them in place, reducing granule loss by up to 90%.

Does oil rejuvenation change the color of a roof like Liqua-Roof?

No. Oil rejuvenation may slightly darken the roof as shingles become saturated with new oils, but it does not offer a full and dramatic colour change. It also maintains the old texture of the shingles and visible wear. Liqua-Roof restores an authentic, granulated, like-new shingle appearance with the option to update roof color without looking painted or glossy.

How is this different than a roof paint?

In a paint or coating, the polymer film is the product - everything else is secondary. With Liqua-Roof, the granules are the primary solid by volume and the primary functional component. They handle impact resistance, UV protection, thermal performance, color, fire resistance, and surface texture. The binder holds them in place. That's not a coating, that's a granule-based roofing surface with a binder as the delivery mechanism.

Think of it like an asphalt shingle: nobody calls a shingle a "coating with embedded granules." The granule is the top protective layer. The binder is what locks it together. The difference is that on a factory-made shingle, granules sit on the surface and shed over time. With Liqua-Roof, the granules are fully embedded in the binder, which means they stay locked in place longer and don't shed.

That's also why we say Liqua-Roof resurfacing, not coating. You're rebuilding the functional surface layer of your roof - with a construction that actually outlasts what came off the factory line.

How does Liqua-Roof Flat compare to traditional liquid-applied roofing in thickness and durability?

Traditional liquid-applied membranes are relatively thin. Liqua-Roof Flat cures into a much thicker (70–80 mils), monolithic, seamless surface reinforced with granules. This results in superior durability, flexibility, and long-term performance, not just waterproofing.

Do liquid-applied roofing systems need reapplication? What about Liqua-Roof?

Yes. Liquid-applied membranes typically require periodic reapplication to maintain performance. Liqua-Roof’s resurfacing system, on the other hand, delivers long-term protection and surface rebuilding in a single application.

Is Liqua-Roof considered a liquid-applied roofing system?

Not in the traditional sense. Liquid-applied roofing creates a waterproof membrane/film, while Liqua-Roof is a roof resurfacing system that adds a new, high-build granule layer to rebuild the protective surface of shingle and flat roofs. It restores what coatings cannot replace: the granulated layer that protects asphalt.

Can liquid-applied roofing be used on shingle roofs like Liqua-Roof?

Typically not. Liquid-applied systems are generally for flat and low-slope roofs (EPDM, TPO, PVC, modified bitumen, metal, concrete). They are not designed for shingles and don’t address granule loss. Liqua-Roof, however, is engineered for both asphalt shingles and flat roofs.

Do liquid-applied membranes rebuild the protective granule layer?

No. Liquid-applied roofing forms a coated or painted film and does not restore lost granules. Liqua-Roof goes further by adding a new, high-build granule layer, reinforcing the roof with real roofing granules, the same material shingles are made from.

How is this different than a roof paint?

When is the ideal time to resurface my roof with Liqua-Roof?

Liqua-Roof is designed to be applied during a roof's mid-life phase, after the initial rapid granule loss has run its course, the underlying asphalt is exposed and slow aging begins. Typically between years 8–15 of a 20–25 year lifespan.

That's the sweet spot where shingles still have enough structural integrity to bond properly with the system, and where Liqua-Roof can increase wind and impact resistance and meaningfully extend roof life. Wait too long and you get past the point of no return. Once more than 20% of shingles need to be replaced, the roof is beyond repair and a full replacement is the only way out. The goal is to catch the roof before it gets there.

Can I repair a section of my roof before applying Liqua-Roof?

Absolutely. One of the key benefits of our system is that it blends repairs seamlessly. Once applied, the entire roof will appear uniform—like brand-new shingles were installed.

When is the best time to apply Liqua-Roof?

The right time to resurface your roof is when you’re starting to think about replacement, but before widespread cracking, curling, or structural damage has occurred.

If you’re noticing granules in your gutters, surface thinning, fading, or early signs of aging, and your roof is still structurally sound, you’re likely in the ideal window.

Liqua-Roof can typically be applied provided no more than approximately 30% of shingles show advanced cracking or curling and the roof structure remains sound. Beyond that point, replacement may be necessary.

Some homeowners also choose Liqua-Roof to change the color of their roof while gaining added protection, at a fraction of the cost, time, and disruption of a full replacement.

If you’re asking whether it’s time to replace your roof, it’s the right time to evaluate Liqua-Roof.

Resurfacing works best before widespread failure begins, not after.

What happens if it rains after application?

While Liqua-Roof has early rain-resistant properties, we only apply it when no rain is forecasted for at least 24 hours.

Can Liqua-Roof be applied to flat roofs?

Yes, Liqua-Roof can be applied to flat roofs with a slight modification. Since flat roofs are more prone to water pooling, we add an extra waterproofing layer—our proprietary resin blend without granules—before applying the granulated topcoat. This creates a thicker, more water-resistant version of our standard system while still delivering the same protective, granulated finish.

Is Liqua-Roof Flat better than silicone roof coatings?

Yes — unlike traditional silicone, Liqua-Roof offers breathability, granule reinforcement, and curb appeal. It performs better over time without yellowing or peeling.

How long does Liqua-Roof Flat last?

Our system is designed for long-term durability and can significantly extend the life of your roof when properly installed. A new layer of protective granules are essentially glued in place providing an armor like barrier to protect the roof.

Is Liqua-Roof Flat slippery like silicone coatings?

No. Our granules add texture for better foot traction, making it safer for roofs with walkability needs.

Can Liqua-Roof be applied to metal roofs?

Liqua-Roof is specifically formulated for asphalt shingle roofs and is not recommended for metal surfaces. Its rough, granular finish wouldn’t be visually suitable for the smooth appearance of metal roofing.

What colors are available?

Liqua-Roof’s base formulation is clear; the color comes entirely from the granules themselves! We offer 4 standard colors based on popular consumer choices (dark brown, light brown, gray, and black). We can, however, match any new shingle color upon request and for a small custom fee.

Is the warranty transferable if I sell my home?

Yes! Our warranty is fully transferable and stays with the home (not just the homeowner) providing peace of mind for you and future buyers.

What are the exclusions of your warranty?

Liqua-Roof is engineered for durability and has passed rigorous ASTM testing for impact, wind, and weather resistance. However, like any roofing system, there are limits in extreme environments.

Our warranty does not cover:
- Damage from foot traffic
- Shingles that were improperly installed or structurally unsound at the time of application
- Storms, high winds, or flying debris
- Improper ventilation or structural leaks
- Mold, mildew, or algae growth

Our team carefully inspects every roof before resurfacing to ensure it’s a suitable candidate for Liqua-Roof. If a roof doesn’t meet our standards, we’ll let you know before proceeding.

How much does Liqua-Roof cost?

Liqua-Roof typically costs less than half the price of a full roof replacement—and often under 40%, depending on roof pitch. While it's slightly more expensive than shingle rejuvenators, it lasts 2–3 times longer and allows you to change your roof color. In terms of durability and benefits, Liqua-Roof is more comparable to a full shingle replacement than to shingle oil rejuvenation.

What type of warranty do you offer?

We offer a 15-year warranty that protects against premature wearing of the surface—specifically, if your original shingle color starts to show through. In the unlikely event that this occurs, our crew will return to your home to reapply our system at no cost to you.

Is Liqua-Roof eco-friendly?

Yes! Roofing materials are the third-largest contributor to landfill waste, with over 20 billion pounds of shingles discarded annually. By extending the life of your existing roof, Liqua-Roof helps reduce this waste and lessens dependence on petroleum-based asphalt. Additionally, our 3-part system is ultra-low in VOCs, making it a more environmentally responsible option.

Is Liqua-Roof toxic?

No. Liqua-Roof is formulated with a high solids content, the majority of which are granules. The remaining proprietary blend also maintains a high solids ratio, with less than 50 g/L of solvents—qualifying it as an ultra-low VOC product. This makes it a safe and environmentally conscious option.

Does Liqua-Roof cause overspray? Can it damage nearby cars orproperty?

Liqua-Roof isn't a roof paint, so overspray isn't really a factor. Paint gets atomized into fine particles to achieve an even finish and that's where overspray comes from. Depending on the application method, transfer efficiency on spray-applied coatings runs between 60–90%, meaning 10–40% ends up as airborne overspray that can drift and damage property if it doesn't dry before hitting the surface. Liqua-Roof is a different animal entirely. It's a paste-like resurfacing system with embedded granules, applied through a large orifice. The concept of overspray doesn't really apply and nothing drifts. It goes where it's directed.

How is Liqua-Roof different from just doing roof repairs?

Repairs are localized — they fix the specific area that's damaged. Liqua-Roof is a whole-roof solution. It adds a new granule layer across the entire surface, locks granules in place with our patented Granulock™ technology, restores uniform color, and protects against the deterioration that makes future repairs inevitable. A repair reacts to a problem. Liqua-Roof gets ahead of the next one.

When should I choose Liqua-Roof instead of roof repairs?

If your roof is structurally sound but showing signs of aging—granule loss, fading, minor wear, or reduced protection—Liqua-Roof is the better choice.

Repairs are ideal for localized damage. But when the whole roof is losing performance, Liqua-Roof rebuilds protection across the entire surface, restoring strength, durability, and appearance in a single application. If, however, you find yourself requiring repairs on more than 15% of your roof, its recommended to consider complete shingle replacement.

Can Liqua-Roof replace the need for future repairs?

Liqua-Roof reduces the need for ongoing repairs by reinforcing shingles with a new, high-build granule layer and bonding resin that locks granules in place.

Homeowners benefit from stronger-than-new performance and dramatically improved impact and weather resistance (plus a 15-year warranty) helping prevent many of the issues that normally require repeated repairs.

Can Liqua-Roof be applied after a roof repair?

Yes — and in most cases, it's the smartest thing you can do after a repair. Once the damaged area is fixed, Liqua-Roof resurfaces the entire roof with a new granule layer, restoring uniform color and reinforcing the surface across every shingle. The repair addresses the damage. Liqua-Roof protects everything that's left.

Why does my repaired roof look patchy or mismatched?

Because new shingles don't match old ones. Shingles fade, weather, and lose granules over time. When a roofer replaces a section, the new shingles are a different color, texture, and granule density than the rest of your roof — and that roofing mismatch is impossible to hide with a standard repair. It's not a workmanship issue. It's a materials reality. The only way to achieve a uniform appearance is to resurface the entire roof surface, which is exactly what Liqua-Roof does.

Is it worth repairing a roof before resurfacing?

Yes. Liqua-Roof is designed to extend the life of a roof in good structural condition — not to cover up active damage. If there are missing shingles, cracked sections, or damaged flashing, those need to be addressed first. Think of repairs as the foundation and Liqua-Roof as the finish. Together, they give you a complete result. Separately, neither one tells the whole story.

Is it worth repairing a roof before resurfacing?

My roofer says I need repairs before any treatment — does that work with Liqua-Roof?

Absolutely. That's actually the right sequence. After our free roof assessment, we will identify any areas that need repair before resurfacing. In many cases, we can coordinate or complete minor repairs as part of the same visit. The repairs happen first, then we resurface the full roof. One process, one result.

Will Liqua-Roof make my repair patches disappear?

Yes. That's one of the most immediate and visible results homeowners notice. Because Liqua-Roof applies a new granule layer across the entire roof — not just the repaired sections — the finished surface is uniform in color and texture from edge to edge. The patches don't just blend in. They disappear entirely and protect the rest of the roof from deterioration giving you a real alternative to roof replacement for a fraction of the cost, time and mess!

Can I get the repair and resurfacing done in one visit?

In most cases, yes. Minor repairs and resurfacing can typically be completed in a single visit. For more significant repair work, we may need to complete repairs first and return to resurface once everything is set. We will walk you through the timeline during your free assessment.

What is the roof matching problem in insurance claims?

When a roof sustains partial damage — from hail, wind, or storm debris — the insurer typically wants to pay for the damaged section only. The problem is that replacement shingles almost never match the existing ones. Shingles fade and weather over time, and once a product line is discontinued, an exact match is often impossible. The result is a visually mismatched roof that looks patchy and can reduce your home's value. Many states have regulations requiring insurers to achieve a "reasonably comparable appearance" after a repair — and when a standard patch job can't deliver that, a full roof replacement may be required instead. That's the insurance roof matching problem.

Do insurance companies have to match my roof shingles after a repair?

It depends on your state. There is no federal matching law. Many states have statutes or regulations requiring insurers to replace as much of a roof as needed to achieve a reasonably comparable appearance. Others rely on case law or individual policy language. In states with strong matching requirements, if a repair can't achieve visual uniformity, the insurer may be obligated to cover a full replacement. Check your policy language and your state's insurance regulations, or speak with a public adjuster to understand your rights.

Can Liqua-Roof help avoid a full roof replacement on an insurance claim?

In many situations, yes. The reason matching requirements trigger full replacements is that there's no other way to achieve visual uniformity after a partial repair. Liqua-Roof changes that. By resurfacing the entire roof with a new granule layer after repairs are made, Liqua-Roof restores a uniform appearance across the whole surface — making a repair outcome visually and regulatorily compliant without requiring full replacement. Whether Liqua-Roof qualifies as an accepted repair method on your specific claim depends on your carrier and your state. Talk to your adjuster and ask them to evaluate it.

Why would an insurance company prefer Liqua-Roof over a full replacement?

Cost. A full roof replacement on an average home runs $15,000 to $25,000 or more. Repair plus Liqua-Roof typically costs a fraction of that. In states where matching requirements would otherwise force a full replacement, Liqua-Roof gives the carrier a compliant, documented, warranted alternative at significantly lower claim cost. It's backed by a 15-year performance warranty and third-party ASTM testing — so the carrier isn't just saving money, they're approving a solution with real performance data behind it. That's a defensible outcome for everyone involved.

Does Liqua-Roof qualify as an approved repair method for insurance claims?

Liqua-Roof is working toward formal recognition as an approved repair method with carriers and industry bodies. As of now, acceptance varies by carrier and by claim. What we can say is that Liqua-Roof is backed by third-party ASTM testing across multiple performance categories — granule retention, impact resistance, wind resistance, breathability, and accelerated weathering — and carries a 15-year performance warranty. That documentation gives adjusters and carriers a legitimate basis to evaluate and approve it. If you're navigating a claim and want to propose Liqua-Roof as an alternative to replacement, ask your adjuster to review our testing documentation. We're happy to provide more details to them as needed.
