Millions of nano particles. A formidable technology.

Our nano coating solution consists of nano particles that transform the molecular structure of materials to modify permanently their properties, enhance their resistance and extend their lifespan by 10 to 15 years.

An alternative to replacing your shingles

If your shingles still have some life left, GoNano can help you get a lot more out of them. Our treatment penetrates the asphalt, restores flexibility and impact resistance, and can add 10–15 years of service life on qualifying roofs, without the mess and cost of a full tear-off. In Kitchener-Waterloo and Guelph’s harsh freeze–thaw cycles, that means fewer leaks, less stress, and more value from the roof you already own.

Nano coatings for roof membranes

Tearing off a membrane roof is one of the biggest line items on any building. Our GoNano roof coating gives you another option. We apply a nanotechnology treatment that bonds with the membrane at the molecular level, sealing micro-cracks, boosting waterproofing, and restoring flexibility. In Southern Ontario’s freeze–thaw cycles, that means fewer surprise leaks, fewer emergency service calls, and 10–15 extra years of use on a roof you already paid for.

Frequently Asked Questions

  • What exactly is GoNano, and how is it different from regular sealers or roof coatings?

    GoNano is a nanotechnology treatment that penetrates deep into shingles, membranes, concrete, and wood instead of just sitting on the surface. At the nanoscale, the particles bond inside the material to make it more water-repellent, flexible, and durable, which can extend its useful life by 10–15 years on many roofs and up to 10 years on many concrete and wood surfaces, depending on condition and product used.

  • How long does the protection last, and is there a warranty?

    On suitable asphalt shingle roofs, GoNano treatments can add up to 10–15 years of extra life, backed by a limited warranty that depends on the age and condition of the roof. Concrete and wood treatments typically come with warranty coverage of up to 10 years when applied to surfaces in good condition. Your exact coverage is confirmed after we inspect your roof or surface and before any work begins.

  • Will GoNano void my existing roof warranty or cause issues with insurance?

    No. GoNano is a non-abrasive, non-destructive treatment that does not tear off or mechanically alter your roof, and dealers report it does not override manufacturer warranties on compatible shingle systems. In many markets, insurers are increasingly open to rejuvenation as a way to reduce premature replacement and claims, but acceptance is always case-by-case, so we’re happy to document our inspection and treatment for your records.

  • Is GoNano safe for my family, pets, and landscaping?

    Yes. GoNano uses biodegradable nano-silica and is formulated without harmful VOCs, so it’s safe to apply around homes, families, pets, and gardens when used as directed. We still take normal precautions, protecting nearby plants and rinsing where needed, but there’s no heavy chemical odour or solvent cloud like some traditional coatings.

  • How do I know if my roof, concrete, or wood is a good candidate?

    The surface has to be structurally sound: GoNano is designed to preserve and enhance what’s there, not repair severe structural damage. For roofs, we look for shingles or membranes that are aging, drying, or losing flexibility but not rotted or badly compromised; for concrete and wood, we check for major cracking, spalling, or rot. That’s why we always start with a free on-site assessment in the Kitchener-Waterloo and Guelph area and include any minor prep or repairs needed before application.

  • What does it cost compared to replacement, and what is the process like?

    Pricing depends on the size, complexity, and current condition of your roof or surface, but homeowners typically pay a fraction of the cost of full replacement for a GoNano treatment. The process is straightforward: we inspect and quote, do any small prep work required, then apply the product, often in a single day, with no dust and minimal disruption. Once it cures, your roof, concrete, or wood is protected and ready for regular use again.
