    Residential Roof Waterproofing & Coating Services

    Residential roof waterproofing adds a protective layer that seals your roof against water and the harsh Alberta climate, and Markit Roofing applies it for homeowners across Calgary and Edmonton who want to extend the life of a sound roof.

    A coating is not a fix for a failing roof, and we are upfront about that. What it does well is protect a roof that is still in good shape, sealing vulnerable areas, reflecting heat, and adding years before replacement becomes necessary. This is particularly valuable on low-slope and flat sections, where water tends to sit rather than run off. Our team assesses whether coating is genuinely right for your roof, recommends the appropriate product, and applies it properly so it performs as intended.

    Done at the right time on the right roof, waterproofing is a smart, cost-effective way to guard your investment. We explain honestly what a coating can and cannot achieve, so you spend money where it actually helps rather than on a treatment that only masks a deeper problem. From the assessment through to a clean, even finish, we treat your roof with the same care we bring to every job.

    What Roof Coating Actually Does for Your Home

    A quality roof coating acts as a seamless barrier over your existing roof surface, sealing the small gaps and weak points where water can enter. On low-slope and flat roofs, especially, this sealing effect guards against pooling that can cause leaks over time. Many coatings also reflect sunlight, easing the heat load on your home in summer and reducing thermal stress on the roof itself. The result is a roof that resists water better and ages more slowly. It is protection and preservation rather than repair, best applied while the roof beneath is still sound.
     
    When Waterproofing Is the Right Choice:
    • Low-slope or flat roof sections where water tends to pool
    • A structurally sound roof with years of life still in it
    • Areas prone to minor water intrusion but not active failure
    • Roofs where extending lifespan is more sensible than replacing
    • Surfaces compatible with the coating being considered
    Coating is a form of preservation, so it works best on a roof that is fundamentally healthy but would benefit from added protection against Alberta’s weather. What it cannot do is rescue a roof that is already failing, since sealing over rotted decking or widespread damage only hides the problem while it worsens underneath. This is why our honest assessment comes first. If your roof is a good candidate, coating is an excellent value. If it is not, we tell you plainly and point you toward what will genuinely serve you.

    Our Process

    Assessing Whether Coating Suits Your Roof

    Everything begins with an honest assessment of whether waterproofing is the right move for your roof. We examine the surface, the slope, the existing material, and the overall condition, because a coating only performs on a roof that is sound to begin with. If we find damage that a coating would simply cover up, we say so rather than selling you a treatment that hides trouble.
     
    Where coating genuinely fits, we confirm the surface is compatible and explain what the product will and will not do for you. This upfront honesty is the whole foundation of the service, since applying a coating to the wrong roof wastes your money and delays a real solution. You get a clear, honest answer on suitability before anything else is discussed, so you never pay for a coating your roof would never have benefited from.

    Preparing the Surface Properly

    A coating is only as good as the surface it bonds to, so preparation is where much of the real work happens. We clean the roof thoroughly, removing dirt, debris, and anything that would prevent the coating from adhering, and we address minor surface issues so the barrier goes on over a stable base. Skipping or rushing this stage is the most common reason coatings fail early, peeling or blistering within a season.
     
    We take the time to do it right, because a properly prepared surface is what lets the waterproofing perform for its full expected life rather than lifting off after the first season. Proper prep is invisible once the job is done, yet it is the difference between a coating that lasts its full life and one that peels away and disappoints within a year.

    Applying the Waterproof Coating

    With the surface ready, we apply the coating evenly and to the correct thickness, paying particular attention to seams, edges, and the penetrations around vents and other roof features where water is most likely to enter. These transition points are where a coating earns its keep, so we make sure they are sealed completely rather than glossed over. Application is done in suitable weather, since temperature and moisture directly affect how a coating cures and bonds to the surface.
     
    We work methodically across the whole surface to create a continuous, unbroken barrier with no thin spots or gaps. The goal is a seamless layer that protects the entire area consistently, not just the parts that were easy to reach, so water has nowhere to slip through once the coating has cured.

    Final Inspection and Ongoing Value

    Once the coating has been applied and allowed to cure, we inspect the finished surface to confirm it is even, complete, and properly sealed throughout. We check the critical seams and edges one more time, since those are where any weakness would first appear, and we clean up the site fully before we leave.
     
    Then we explain what to expect from the coating going forward and how simple maintenance, like keeping the surface clear and checking it periodically, can help it reach its full lifespan. A good coating is a long-term asset, quietly protecting your roof year after year against water and weather, and we want you to get every bit of that value from it. If anything about the finish is not right, we address it before considering the job complete.

    Why Homeowners Choose Markit Roofing for Waterproofing

    The most valuable thing we bring to waterproofing is telling you the truth about whether your roof needs it. A coating is a genuine benefit on the right roof and a waste of money on the wrong one, and plenty of companies will happily apply it either way. We will not. If your roof is sound and coating adds real, lasting protection, we recommend it with confidence. If your roof is failing and a coating would only mask the problem, we say so and steer you toward a repair or replacement instead. That honesty protects your money, and it is exactly why homeowners trust our recommendation on waterproofing rather than treating it as a sales pitch designed to move product.
    Most coating failures trace back to poor surface preparation, and this is where we refuse to cut corners. A coating applied over a dirty or unstable surface will peel, blister, or lift within a season, wasting the whole investment. We clean and prepare the roof thoroughly so the waterproofing bonds properly and performs for its full expected life. It is unglamorous work that a homeowner never sees once the finish is on, but it is the single biggest factor in whether a coating lasts. Getting the foundation right is how we make sure the protection you paid for actually holds up against Alberta weather season after season, rather than lifting off within the first year.
    Not every coating suits every roof, and matching the product to the surface, slope, and conditions matters as much as the application. We assess what your roof actually needs and recommend a waterproofing system suited to it, rather than applying whatever is on hand. The wrong product can fail to bond or break down quickly, undoing the benefit entirely. Because we work on residential roofs here every day, we know which systems hold up to our climate and which do not. Choosing correctly at the outset is part of what makes the difference between a coating that protects for years and one that disappoints early, and it is a judgement built on doing this work locally every day.
    Waterproofing has to stand up to what Alberta throws at it, from intense summer sun to deep winter freeze and the constant cycle between them. We apply coatings with those specific demands in mind, at the right time of year and in the right conditions for a proper cure. A treatment applied without regard for our climate can fail to bond or degrade quickly, which is exactly why local experience matters so much here. Because we understand how these roofs and these seasons behave over the years, we apply waterproofing in a way that actually performs through them, giving you protection that lasts rather than a finish that looks good only until the first hard winter arrives.

    Coating Options and What We Offer

    Different roof coatings suit different roofs and different priorities, and understanding the main types helps you see why we recommend one over another for your particular home. The options below are the most relevant to residential roofs in Calgary and Edmonton, each with its own strengths and ideal use. We match the choice to your roof’s surface, slope, drainage, and condition rather than favouring a single product, so the recommendation you get reflects what will genuinely perform on your roof rather than what’s easiest for us to apply.

    Acrylic Coatings

    TPO Roofing
    Acrylic coatings are a popular choice for many residential roofs, valued for their reflectivity and reasonable cost. They reflect sunlight well, helping keep a home cooler in summer and reducing heat stress on the roof. Acrylics work best on roofs with some slope where water drains rather than sits, since they are less suited to areas of standing water. On the right surface, they offer solid, affordable protection and a bright, reflective finish that eases the summer heat load.

    Silicone Coatings

    Silicone coatings excel where water tends to pool, making them a strong option for low-slope and flat residential sections. Unlike some coatings, silicone stands up well to standing water without breaking down, which is exactly the challenge those roofs face. It also resists the effects of sun and weather over time. Where ponding is a concern and durability against moisture matters most, silicone is often the product we recommend, since it holds up in the conditions that defeat lesser coatings.

    Elastomeric Coatings

    Elastomeric coatings are prized for their flexibility, stretching and contracting with the roof as temperatures swing. That elasticity matters a great deal in Alberta, where roofs expand in summer heat and contract in deep cold, and a rigid coating would crack under that movement. By flexing with the surface, elastomeric coatings maintain their seal during the freeze-thaw cycle. For a climate as variable as ours, this ability to move without splitting makes them a durable, weather-ready choice.

    Reflective Cool Roof Coatings

    Reflective, or cool roof, coatings focus on bouncing sunlight away rather than absorbing it, and their appeal in summer is easy to feel. By reflecting solar heat, they keep the roof surface and the home beneath it cooler, easing your cooling load and reducing the thermal stress that ages a roof. Many acrylic and elastomeric products carry these reflective properties built in. On a home that heats up under Alberta’s strong summer sun, a reflective finish adds real comfort and protection, in addition to its waterproofing role.

    Choosing the Right System

    With several coating types available, the right choice depends on your roof rather than a one-size answer, and that is where our assessment earns its value. We weigh the slope, the roof surface material, drainage, and how the roof handles our seasons, then recommend the system that best fits. A coating matched to the roof performs for years, while a mismatched one fails early regardless of quality. Our job is to make that match correctly, so your investment in waterproofing delivers the lasting protection it should.
