COMMERCIAL ROOF REPAIR & REPLACEMENT SERVICES

Setting the Highest Standards in Roofing and Building Envelopes

Commercial roofs face Alberta’s extreme weather — freezing winters, heavy snow loads, intense summer UV and sudden hailstorms. Timely professional repair or full replacement is the only way to protect your building, employees, inventory and bottom line.

A failing roof leads to leaks, structural damage, energy loss and expensive business downtime. At Markit Roofing, our certified team provides expert commercial roof repair and replacement services across Calgary and Edmonton, using premium materials and proven techniques for every roof type — flat, low-slope, steep-slope and standing seam metal systems

Our Roof Replacement Solutions

We deliver complete, tailored commercial roof replacement solutions for your exact building needs:

Our experts first inspect your existing roof, then recommend the smartest replacement option that maximizes durability, energy savings and return on investment.

Commercial Roof Leak Repairs

Roof leaks in commercial buildings pose an immediate threat — they can halt daily operations, ruin ceilings, ruin expensive equipment, destroy inventory, and even trigger mold growth within just hours of water intrusion.

Our certified technicians use advanced leak detection methods, including infrared scanning and electronic moisture mapping, to precisely locate the source without unnecessary demolition. We then perform targeted, high-quality repairs using premium sealants, membranes, and flashing techniques to stop leaks instantly.

This rapid response minimizes business downtime, prevents secondary damage, and restores complete waterproof protection for your Calgary or Edmonton facility, backed by our long-term workmanship warranty.

Flat & Low-Slope Roof Repair

Flat and low-slope roofs are the most common choice for commercial properties across Alberta due to their cost-effectiveness and design flexibility, yet they demand specialized expertise because of ponding water risks, membrane vulnerability, and extreme weather exposure.

We expertly address common issues like punctures from debris or HVAC traffic, failed seams, surface blistering, alligatoring, and chronic ponding caused by poor drainage. Using proven restoration techniques — such as targeted patching, seam reinforcement, coating applications, and tapered insulation additions.

We fully restore waterproof integrity, improve energy performance, and significantly extend the roof’s service life. Our solutions are tailored to Alberta’s freeze-thaw cycles and heavy snow loads for lasting reliability.

Structural Roof Repairs

When water infiltration, age, or excessive loading causes decking, joists, purlins, or other support structures to weaken, rot, or corrode, the entire building’s safety becomes compromised — risking partial or full collapse under Alberta’s snow and wind demands.

Our experienced structural teams conduct thorough assessments, including core sampling and load calculations, then reinforce or completely replace damaged sections with code-compliant materials like treated lumber, steel plating, or engineered composites.

We ensure full restoration of structural integrity while strictly adhering to or exceeding the Alberta Building Code and National Building Code of Canada requirements. This critical work safeguards occupants, protects your investment, and prevents far more expensive emergency interventions later.

Commercial Roof Replacement

When ongoing repairs become uneconomical, frequent leaks persist, energy bills skyrocket due to failed insulation, or the roof approaches or exceeds its expected lifespan (typically 15–30+ years), a full commercial roof replacement delivers the best long-term value and peace of mind.

We safely remove the existing system, dispose of debris responsibly, inspect and repair the substrate if needed, then install modern, high-performance roofing — including energy-efficient membranes, superior insulation, enhanced drainage, and reflective coatings optimized for Alberta’s harsh UV, hail, and temperature swings.

The result is maximum durability, reduced operating costs, improved building envelope performance, and comprehensive new manufacturer plus workmanship warranties up to 20 years.

Different types of commercial roof issues

Persistent leaks often stem from torn or aged membranes, failed seams, deteriorated flashing around penetrations, or improper edge detailing. In commercial buildings, even small leaks can quickly lead to serious problems: saturated insulation reduces energy efficiency, water stains and mold appear on ceilings, electrical systems risk short-circuiting, and valuable inventory or equipment gets damaged. Business operations face costly interruptions, potential health hazards from mold, and insurance complications. Prompt professional intervention prevents escalation into major structural issues and expensive downtime in Calgary or Edmonton facilities.

Membrane cracks, holes, and punctures commonly result from heavy foot traffic during maintenance, falling debris, hail impact, sharp tools, or extreme thermal expansion/contraction in Alberta’s fluctuating weather. These openings completely compromise the roof’s waterproof barrier, allowing direct moisture penetration that leads to interior leaks, wet decking, rot, and accelerated insulation failure. Over time, untreated damage spreads, weakening the entire system and raising repair costs dramatically. Regular inspections and timely patching are essential to maintain watertight integrity and protect commercial assets long-term.

Blistering appears as raised bubbles under the membrane surface, while alligatoring shows deep, cracked patterns resembling reptile skin. Both issues arise from trapped moisture during installation, prolonged UV exposure breaking down the top layer, poor adhesion, or inadequate ventilation. These surface defects reduce the membrane’s flexibility and thickness, creating weak points prone to splitting and eventual leaks. In harsh Alberta conditions with intense sun and freeze-thaw cycles, they accelerate overall deterioration. Early detection through professional roof assessments can prevent full membrane failure and extend system lifespan significantly.

Aging commercial roofs gradually lose their protective granule layer, become brittle, crack under thermal stress, and suffer reduced flexibility from decades of UV radiation, heavy snow loads, freeze-thaw damage, and wind exposure typical in Alberta. Insulation value drops as materials compress or absorb moisture, leading to higher heating/cooling costs and energy inefficiency. Structural strength weakens as decking rots or corrodes, increasing collapse risk under accumulated weight. Without proactive maintenance or timely replacement, aging roofs become unreliable, frequently leak, and pose safety threats to occupants and property.

COMMON COMMERCIAL ROOF REPAIR & REPLACEMENT SOLUTIONS

Commercial buildings demand durable, efficient roofing to keep operations safe and uninterrupted. The right solution depends on your roof type, damage level, building size and future goals.

Which solution is right for your commercial roof?

The appropriate solution depends on the roof type, extent of damage, building size, and long-term performance goals.

Typically, these repair and replacement solutions are used:

Roof Patching

Quick, targeted fixes address small isolated damage like punctures, seams, or minor cracks. It restores immediate waterproofing without disrupting your entire roof system. This cost-effective option extends roof life significantly while minimizing business downtime.

Membrane Replacement

Full or sectional replacement uses premium single-ply or modified bitumen membranes. It delivers superior waterproofing, excellent UV resistance, and enhanced energy efficiency. Ideal when widespread membrane failure occurs but the underlying structure remains sound.

Full Roof Replacement

Complete removal of the old system followed by installation of modern, high-performance roofing. Chosen when the existing roof is beyond economical repair or nearing end-of-life (15–30+ years). Provides long-term durability, better insulation, energy savings, and comprehensive new warranties.

Flashing Replacement

Critical junctions, penetrations, edges, and joints are resealed or fully replaced with durable materials. It eliminates major water entry points that cause persistent leaks and interior damage. Essential preventive work that protects the entire roof assembly and extends overall system life.

Structural Reinforcement

Damaged decking, supports, or load-bearing elements are strengthened or replaced as needed. Restores full safety, structural integrity, and compliance with building codes. Critical when weakening from water damage, age, or heavy loads risks collapse or further deterioration.
