Commercial Roof Leak Inspection

The most dangerous roof leaks are the ones you cannot see. Water travels far from its point of entry and saturates the insulation long before a stain appears on the ceiling below. Markit Roofing finds these hidden problems across Calgary and Edmonton using infrared thermal imaging, electronic leak detection, and moisture mapping, without tearing your roof apart.

A professional inspection tells you exactly where your roof stands and what it needs, turning guesswork into a clear action plan. Whether you are buying a building, filing an insurance claim, or protecting an existing asset, our certified team delivers detailed, photo-backed findings. Book your commercial roof inspection today.

Signs Your Commercial Roof Needs a Full Inspection

An inspection is not only for when something has already gone wrong. The smartest time to check a commercial roof is before a problem forces your hand, when there is still room to plan repairs calmly. Several moments in a building’s life make a professional commercial roof inspection especially worthwhile for your property in Calgary or Edmonton.
In each of these situations, a documented inspection protects you from unwelcome surprises and gives you real leverage in negotiations, insurance claims, and planning. Our certified team scans the entire roof, verifies every finding with hard data, and hands you a report clear enough to act on with total confidence and no lingering guesswork.

Our Full Roof Inspection Steps

Detailed Visual Assessment

Our commercial roof inspection begins on foot, with a trained technician walking the whole roof to assess its condition. We examine the membrane, seams, flashings, penetrations, drains, and rooftop equipment, noting any cracks, blisters, ponding marks, or other damage.
 
Water rarely enters where it appears indoors. It travels along the deck, through insulation joints, and down structural members before it stains a ceiling tile, which is why a stain twenty feet from the actual breach is completely normal and why walking the roof matters before any instrument comes out.

Infrared Thermal Scanning Work

Next, we scan the roof with an infrared thermal imaging camera to reveal what the eye cannot. Wet insulation holds heat differently from dry material, so trapped moisture shows as distinct thermal signatures. The method follows ASTM C1153, the standard for infrared moisture surveys.
 
Thermal scanning works best under the right conditions, so we scan after sunset when the thermal contrast between wet and dry zones peaks. The moisture map pinpoints exactly where water entered, letting any repair target the real problem instead of guessing.

Precise Electronic Leak Testing

Where the scan flags a suspect area, we confirm it with electronic leak detection and moisture meters. Low-voltage testing traces the path water takes through a membrane, while probes read moisture as a percentage at set points, separating real leaks from surface anomalies.
 
Confirming findings before we report them is what makes our inspections trustworthy. Rather than tearing up sound roofing on a hunch, we determine where moisture is and isn’t. That accuracy spares you unnecessary work and keeps every repair recommendation justified by data.

Full Written Condition Report

Finally, we compile everything into a clear report you can actually use: annotated photos, thermal images, moisture maps, and a plain summary of each finding, its severity, and cause, prioritised by urgency.
 
We walk you through the report in person, answer questions, and outline next steps, whether that is a roof coating system, a full roof replacement, or simply a scheduled maintenance program. This documentation supports insurance claims and property sales, giving Alberta managers a solid foundation for every roofing decision.

Detection Tools We Use to Find Hidden Roof Leaks

Infrared thermal imaging is the backbone of modern leak detection on flat commercial roofs. Wet insulation and dry membrane release stored heat at different rates, so a thermal camera reveals trapped moisture as clear temperature patterns invisible to the naked eye. We systematically scan the entire roof, capturing thousands of readings that map exactly where water has soaked into the assembly. This non-invasive technology quickly identifies hidden saturation across large Calgary and Edmonton rooftops, guiding precise repairs rather than guesswork or unnecessary tear-offs.
Moisture meters give us the hard numbers that confirm what a thermal scan suggests. By probing the roof at targeted points, these instruments measure the actual moisture content within the membrane, insulation, and deck. We use them to verify thermal anomalies and to check areas the camera cannot reach cleanly, such as around HVAC curbs and complex flashing details. Combining meter readings with thermal maps gives a reliable, cross-checked verdict on your commercial roof, so no repair decision on your Alberta building rests on a single data source alone.
For the most precise pinpointing, electronic low-voltage leak detection traces the exact route water travels through a roofing membrane. The method applies a small charge across the surface and follows the electrical path moisture creates, marking breaches down to a specific point rather than a general zone. It is exceptionally accurate for single-ply systems such as TPO and PVC. This precision means our crews repair only the failed area, protecting sound roofing and keeping disruption to your Calgary or Edmonton building to an absolute minimum.
Some situations call for physical confirmation, and that is where core sampling and drone surveys come in. A small core cut from a flagged area shows exactly how far moisture has penetrated the layers below and how much insulation is saturated, which determines whether a patch or a section replacement is needed. The core is sealed and patched before we leave. For steep, high, or hard-to-reach sections, a drone captures detailed aerial imagery safely without anyone leaving the ground.

What Makes Our Inspection Reports Worth Acting On

Markit Roofing brings certified inspectors, advanced detection technology, and clear reporting to every commercial roof inspection we carry out across Calgary and Edmonton. Our team includes HAAG-certified inspectors, a credential focused on roof damage assessment, so findings carry weight with insurers and buyers alike.

Inspectors Who Read Roofs Right

Our inspectors are trained and certified to read commercial roofs the way few others can, interpreting thermal signatures, moisture readings, and physical wear into a coherent diagnosis. They know how TPO, EPDM, and modified bitumen systems age across Alberta, so findings reflect roofing experience, not a camera image alone. A thermal anomaly means little without knowing the assembly. That expertise turns raw data into recommendations you can genuinely rely on.

Non-Destructive Testing Methods

Every method we use is non-destructive, so a thorough inspection never means cutting into a sound roof to find out what is wrong. Infrared scanning, moisture meters, and electronic detection reveal hidden problems from the surface, leaving your membrane intact and your warranty untouched. This protects the roof we are assessing and allows an inspection to be repeated as often as your building needs without introducing any new points of failure.

Clear Photo-Backed Reporting

An inspection is only as useful as the report it produces, so ours are built to be understood and acted on. We deliver annotated photos, thermal images, and moisture maps alongside plain-language findings and prioritized recommendations. This evidence-backed documentation supports a roof insurance claim, guides property sales, and gives Alberta managers a confident basis for planning repairs on their roof.

Alberta Climate Knowledge Base

Alberta’s climate is unlike anywhere else, and our inspections are built around it. We understand how Chinook swings, hail, heavy snow loads, and deep freeze-thaw cycles attack commercial roofs, and we know the failure patterns each one leaves behind. That local insight sharpens every scan and every recommendation, so your inspection reflects the real forces working on your Calgary or Edmonton roof, not a generic checklist.

Fast, Reliable Report Delivery

Findings are worth little if they arrive too late to be useful. We turn inspection reports around within days because insurance claim windows often close within 12 months and purchase conditions run even shorter. You get your annotated photos, moisture maps, and prioritised recommendations while there is still time to act on them, not weeks after the decision has already been forced on you.
