    Commercial Roof Waterproofing & Roof Coating

    An ageing flat roof does not always need a full replacement. A quality waterproofing or coating system can seal leaks, restore performance, and add years of life for a fraction of the disruption. Markit Roofing applies fluid-applied, seamless commercial roof waterproofing systems across Calgary and Edmonton, turning a tired, leak-prone roof into a watertight barrier without a tear-off.

    Elastomeric, silicone, and reflective coatings bridge cracks, resist ponding, and reflect harsh UV, extending the life of the roof you already have. Applied over your existing membrane, they seal seams and fasteners into one continuous surface. Book your waterproofing and coating assessment today.

    Signs Your Flat Roof Needs a Protective Coating Now

    A coating is not right for every roof, but for many it is the smarter move. When the structure and decking are still sound, but the surface is worn, a fluid-applied system restores watertightness without the disruption and downtime of tearing everything off. Several conditions make your Calgary or Edmonton roof a strong candidate for coating.
    • The roof is structurally sound
    • Multiple small surface leaks
    • High summer cooling bills
    • Chalking or surface cracking
    • Warranty has expired
    If your roof fits this picture, a coating can add ten or more years of protected service and improve energy performance at the very same time. A moisture survey settles it, telling you plainly whether a coating will deliver or a full roof replacement is the wiser path. We never coat a roof that is too far gone to benefit from it.

    Our Coating Application Process

    Inspect and Test the Surface

    Before any coating goes down, we assess whether the roof is a sound candidate. We inspect the membrane, check the decking for moisture, and run an adhesion test so the new coating bonds permanently. Moisture readings confirm no trapped water that would blister beneath a fresh coat.
     
    This matters because a coating completely seals the roof. Any water already sitting in the insulation stays there permanently, continuing to rot the deck out of sight. If we find saturation, we say so plainly, because coating a wet roof buys nothing and hides the damage until it becomes structural.

    Clean and Prep the Roof Surface

    A coating is only as good as the surface beneath it, so preparation is where much of the work happens. We power-wash the entire roof to strip away dirt, chalk, and growth, then let it dry completely. Loose material is removed and the surface left clean for adhesion.
     
    Skipping preparation is the most common reason coatings fail early, so we never rush it. A properly cleaned and dried substrate allows the coating to adhere tightly and cure into a continuous film. This groundwork is invisible once finished, but it makes the waterproofing last for years.

    Reinforce Seams and Details

    Coatings fail first at the details, so before the field coat, we reinforce every vulnerable point. Seams, flashings, fasteners, and penetrations are bedded in thick waterproofing mastic, often with polyester fabric that bridges movement. These are where water tries hardest to get in.
     
    Reinforcing the details first means the finished system has no weak links waiting to open up. By the time the field coating goes on, every seam and transition is already sealed. This layered approach gives a fluid-applied roof its seamless, watertight integrity.

    Apply the Seamless Coat System

    With the details reinforced, we apply the field coating in even, controlled coats to the manufacturer’s specified thickness. Elastomeric systems cure roughly 10 times thicker than paint, and we measure wet-film depth on every pass to ensure the finished membrane reaches full strength.
     
    We monitor conditions and cure times to ensure the coating sets properly in Alberta’s climate. Once cured, the roof is a flexible, watertight membrane with no seams to fail. We inspect the surface and hand you a roof that sheds water and resists UV for years.

    Coating and Waterproofing Systems We Install Here

    Acrylic elastomeric coatings are a versatile, widely used choice for restoring flat and low-slope commercial roofs. Applied as a thick, flexible film many times heavier than paint, they stretch and recover with the roof’s daily thermal movement, bridging hairline cracks and sealing the surface against water. Their bright white finish reflects UV and can cut peak rooftop surface temperature by 30 degrees or more through Alberta summers. We apply acrylic systems over sound membranes, metal, and modified bitumen, giving your building a seamless, reflective barrier that renews the roof.
    Silicone coatings excel in areas where ponding water is a persistent problem, making them a strong fit for many flat roofs in Alberta. Unlike acrylics, silicone does not re-emulsify in standing water, so it maintains its seal in low spots where water lingers after snowmelt. It resists UV well and stays flexible for years without becoming brittle. The trade-off is that silicone retains dirt and becomes slippery when wet, so we broadcast granules over walkway areas during application.
    Polyurethane coatings provide exceptional toughness for roofs subject to physical abuse. Their high tensile strength and abrasion resistance suit roofs with regular foot traffic, rooftop equipment, or areas prone to impact and mechanical wear. Often applied as a two-part system with an aromatic base coat and a UV-stable topcoat, polyurethane forms a rugged, fully bonded membrane. We recommend it for high-traffic commercial roofs and plaza decks where durability matters most, giving your Alberta building a waterproof surface built for demanding daily use.
    Reflective cool roof coatings tackle heat and energy performance head-on, and they suit Alberta’s bright, high-altitude sun perfectly. A brilliant white surface reflects the sun’s rays rather than absorbing them, lowering rooftop temperatures and easing the load on air conditioning throughout summer. Lower surface heat also slows the thermal cycling that ages a membrane, so the roof lasts longer too. We apply reflective systems to reduce cooling demand and extend roof life, delivering both waterproofing and real energy savings for your property.

    Why Our Coating Work Holds Up Across Alberta Roofs

    Markit Roofing restores and waterproofs commercial roofs across Calgary and Edmonton with fluid-applied waterproofing systems that seal leaks and extend service life without a tear-off. We hold manufacturer accreditations including IKO and Firestone certified contractor status, so applicators install the systems we apply that those manufacturers recognise.

    Applicators Trained per System

    Coating is a specialised craft, and our applicators are trained and certified in the systems they install, including acrylic, silicone, and polyurethane. They know how to read a substrate, hit the correct film thickness, and detail every seam. Most coating failures trace back to under-application, not to the product itself. That expertise is why our coatings bond tightly and last, rather than peeling off a poorly prepared roof a season later.

    No-Tear-Off Roof Restoration

    A coating restores your roof without the mess, noise, and downtime of a full tear-off. There is no ripping off the old membrane, no exposed deck, and no waste heading to landfill, just a clean application straight over your existing roof. Your business keeps running normally throughout, and you extend the life of the roof you already own instead of paying to replace it years too early.

    Seamless Watertight Barriers

    Every system we apply cures into one continuous, monolithic membrane with no seams or laps to fail. Because the coating is fluid-applied, it flows into every detail and forms a single surface, typically recoatable every 10 to 15 years. This seamless quality is exactly what makes fluid-applied commercial roof waterproofing so reliable, sealing the roof against water far more dependably than any sheet system joined together at seams.

    Built for Alberta's Climate

    We select and apply every coating for the specific demands of Alberta weather, from intense high-altitude UV to deep freeze-thaw cycles and stubborn ponding. That means silicone where water pools, reflective white where heat is the enemy, and tough polyurethane where traffic wears a roof down. Matching the system to real local conditions is why our commercial roof waterproofing keeps performing when generic coatings would fail.

    Manufacturer-Backed Warranties

    The coating systems we apply carry manufacturer warranties, but only when installed by certified applicators at the specified film thickness. We register your coating with the manufacturer and provide the documentation, along with the scheduled maintenance record, to keep coverage enforceable. This paperwork matters years later, when a claim depends on proving the system went down exactly as intended.
