Commercial Roof Inspection & Leak Detection Service

A commercial roof inspection gives you something most building owners never actually have: an honest, evidence-backed picture of what condition your roof is really in. Guessing at a roof’s health, or trusting a contractor who profits from the repair they recommend, leaves you exposed to both surprise failures and unnecessary spending.

Markit Roofing provides independent inspection and leak detection for commercial and industrial buildings in Calgary and Edmonton, focused on finding facts rather than selling work. We survey the roof systematically, trace leaks back to their true source rather than the spot where water shows up inside, and document everything with photographs and clear notes.

What you receive is a straightforward report on the roof’s condition, the location and likely cause of any leaks, and a sensible timeline for acting, with no pressure and no inflated list of repairs. Whether you need due diligence before buying a building, evidence for an insurance claim, a baseline for planning, or an answer to a stubborn leak, our job is to tell you the truth about your roof so you can make a confident decision.

Why an Honest Inspection Matters

The value of an inspection lies entirely in its honesty, and that is where many fall short. When the party inspecting the roof is also the one hoping to win the repair, the findings can quietly drift toward whatever generates the biggest job. An independent assessment removes that conflict. You learn what is genuinely wrong, what can safely wait, and what needs attention now, based on evidence rather than sales pressure. For decisions that carry real money- a building purchase, an insurance claim, a capital plan- that impartial clarity is worth far more than a free look with strings attached.
 
 
What Our Inspection Examines:
Each area tells part of the story, and read together they reveal not just where a roof is today but where it is heading. We record findings against each, so you can see not only that a problem exists but also how serious it is and how soon it needs to be addressed. This turns a vague sense that the roof is old into a specific, prioritised understanding of its condition, which is what makes an inspection genuinely useful rather than just reassuring.

Our Process

Understanding Why You Need the Inspection

An inspection is only useful if it answers your actual question, so we start by understanding why you need it. It could be due diligence before a property purchase, an insurance claim, a chronic leak, a warranty requirement, or simply a baseline for planning each call for a slightly different focus and depth. A pre-purchase survey assesses remaining life and hidden liabilities, while a leak investigation focuses on tracing a specific fault.
 
By clarifying the purpose first, we ensure the inspection and report deliver what you can actually use, rather than a generic once-over. This upfront conversation also sets expectations on scope and turnaround, so you know exactly what you are getting and when, and the findings land as answers to your question rather than a pile of observations you have to interpret yourself.

Systematic Survey of the Whole Roof

With the purpose clear, we survey the entire roof methodically rather than sampling a few spots. Working across the surface, we assess the membrane, seams, flashing, drainage, penetrations, and rooftop equipment against a consistent checklist, so nothing is skipped and every finding is comparable. A flat commercial roof hides most of its problems at transitions and low points, so a partial look misses exactly what matters.
 
We note the condition of each element, photograph what we find, and record enough detail to support a clear report and, where relevant, a claim. This systematic coverage is what separates a real inspection from a quick glance. It ensures the picture you get is complete, evidence-based, and specific to your roof, not a general impression coloured by whatever caught the eye first.

Tracing Leaks to Their True Source

Leak detection is its own discipline because water rarely enters where it appears to come from. It travels along the underside of the membrane, across decking, and down structure before it drips through a ceiling, often metres from the actual breach. Chasing the visible stain leads to repairs that fail, so we trace leaks back to their genuine origin.
 
We follow the water’s likely path, examine the suspect seams, penetrations, and flashing upslope, and check for the trapped moisture that reveals where the membrane has been compromised. Pinpointing the real source is what turns a repeat leak into a fix that holds. Rather than guessing and hoping, we identify the true failure point so that any repair, whether done by us or anyone else, addresses the cause rather than the symptom.

Reporting Findings You Can Act On

The inspection produces a clear, documented report rather than a verbal impression you have to trust and forget. We set out the roof’s overall condition, the specific issues found, their severity, and a sensible timeline for addressing them, supported by the photographs taken on site. Where there are leaks, we state the located source and the likely cause in plain terms. Critically, we separate what needs action now from what can be monitored, so you are not pushed toward unnecessary work.
 
This report is yours to use however you need, to plan a budget, support a claim, inform a purchase, or brief another contractor. The goal is a document that gives you genuine decision-making power over your roof, grounded in evidence and free of any pressure to buy, so the value stays with you long after we have left the site.

Why Choose Markit Roofing for Inspection

Our inspection exists to give you facts, not to manufacture a job, and that independence is the whole point. We report what the roof actually needs, clearly separating urgent problems from issues that can safely be watched, so you never feel steered toward spending you did not need. Because we are willing to tell you the roof is fine, or that a problem can wait, our findings carry real weight when we do flag something serious. You get an assessment you can trust precisely because it is not built to sell you the maximum possible repair. For any decision resting on the roof’s condition, that impartiality is the single most valuable thing an inspector can offer, and it is the standard we hold ourselves to on every report.
Finding the true source of a leak takes method and experience, not a quick look at the stain and a hopeful patch. Our team understands how water moves through a commercial roof assembly and traces it back to the actual point of failure, including the hidden moisture that gives away a compromised membrane. This matters because a misdiagnosed leak simply returns, costing you a second repair and more interior damage. By identifying the genuine origin, we ensure any fix that follows is aimed at the right place. That diagnostic rigour is what separates a leak that is truly solved from one that is merely quiet until the next heavy rain finds the same unaddressed fault.
Our reports are built to be genuinely useful documents, not throwaway summaries. Clear findings, severity ratings, timelines, and photographic evidence give you something you can put in front of an insurer, a buyer, a lender, or your own board with confidence. This evidence supports insurance claims, informs purchase negotiations, and forms a defensible basis for capital planning. Because the documentation stands on its own, it retains value long after the visit, whether you act on it immediately or file it as a baseline. Many owners find the report alone justifies the inspection, giving them proof and clarity they can rely on in exactly the moments where a vague opinion would not hold up.
We deliver the findings and then leave the decision to you, with no push to sign for work on the spot or before you have had time to think. You are free to act on the report yourself, hand it to another contractor, or simply keep it as a record, and the assessment stands regardless of what you choose. This no-pressure approach reflects what an inspection is genuinely for: giving you knowledge and control, not funnelling you into a contract. Should you choose us for any resulting work, that is your decision made on the merits, not a condition of getting honest answers in the first place. That freedom is exactly why an independent inspection earns the trust that a sales-driven one never can.

Understanding Your Inspection Report

An inspection is most valuable when you know how to read and use what it tells you, so it helps to understand what the report covers, how findings are prioritised, and when different situations call for one. This section walks through the practical side of commercial roof inspection and leak detection, from how often to inspect to how the findings fit alongside insurance and purchase decisions. The aim is to help you get real value from the assessment, treating it as a decision-making tool that gives you clarity and evidence rather than just another item ticked off a facilities checklist.

How Often to Inspect a Commercial Roof

A commercial roof generally warrants inspection at least once or twice a year, along with a check after major storms and whenever a leak appears. Age and history shift that: a newer roof may need less, while an older roof or a building with a claims record may benefit from closer attention. Inspection also makes sense at key moments, before buying a building, at warranty milestones, or when planning budgets. Timing it to those decision points is where an inspection earns its keep.

What the Report Actually Contains

A good inspection report is a working document, not a one-line verdict. Ours sets out the roof’s overall condition, each specific finding, a severity rating, and a suggested timeline for action, all backed by the photographs taken on site. Where leaks were investigated, the report states the identified source and likely cause. That structure means you can hand the same report to a lender, an insurer, or another contractor and each will find what they need. The details are what make it useful long after the visit itself.

How Findings Are Prioritised

A useful report does not treat every finding equally, because not every issue demands the same response. We rate what we find by severity and urgency, separating faults that require prompt action from those that are safe to monitor, and those that are merely cosmetic. This lets you spend sensibly, addressing genuine risks first rather than reacting to a flat list of everything imperfect on the roof. It also gives you a defensible order of works to budget against, so the report becomes a staged plan rather than a catalogue.

Inspection for Insurance and Claims

When storm or hail damage is involved, a documented inspection becomes valuable evidence. Our photographic findings and clear account of what failed and why give an insurer a solid basis for assessing a claim and help distinguish sudden, covered damage from gradual wear that may not be. An independent report strengthens your position and reduces the disputes that vague claims invite. We do not decide your coverage, but the evidence we provide is the kind of documentation that supports a fair, straightforward assessment.

Inspection Before Buying a Building

For anyone purchasing a commercial property, the roof is one of the largest hidden liabilities, and a pre-purchase inspection removes the guesswork. We assess remaining service life, existing faults, and likely near-term costs, so you enter negotiations knowing what the roof will demand of you. That knowledge can inform the price, shape conditions, or simply prevent an expensive surprise after closing. A modest inspection cost here routinely saves a great deal later, turning an unknown risk into a quantified factor.
