Common Issues Detected in Commercial Roof Inspections
Commercial roof inspections are essential for identifying potential problems that could compromise the integrity and safety of your building. Here are some of the most common issues detected during these inspections:
Roof Leaks
Roof leaks are a prevalent issue in commercial buildings and can be caused by various factors such as damaged or missing shingles, cracked flashing, or clogged drainage systems. Leaks can lead to significant property damage, including mold growth, structural weakening, and damaged insulation.
Ponding Water
Ponding water, or water accumulation, is a frequent problem on flat or low-sloped commercial roofs. It occurs when water does not drain properly and remains on the roof surface for more than 48 hours. This can lead to roof deterioration, structural damage, and even roof collapse if not addressed promptly.
Membrane Shrinkage
In single-ply roofing systems, membrane shrinkage is a common issue. This occurs when the roofing membrane contracts, leading to pulled seams, cracks, and other forms of damage. Membrane shrinkage is primarily caused by prolonged exposure to UV rays and high temperatures.
Punctures and Penetrations
Punctures and penetrations in the roof can result from various factors, including foot traffic, fallen debris, or the installation of rooftop equipment. These openings can allow water to enter the building, leading to further damage.
Blistering and Cracking
Blistering and cracking of the roof surface are signs of deterioration often caused by prolonged exposure to the elements. These issues can compromise the roof’s waterproofing capabilities and lead to leaks.
Clogged Gutters and Drains
Clogged gutters and drains can cause water to back up onto the roof, leading to ponding water and potential leaks. Regular maintenance is essential to keep these drainage systems clear and functioning properly.
Rust and Corrosion
Rust and corrosion are common in metal roofing systems and can indicate excess moisture and the weakening of roof components. This can lead to structural issues if not addressed.
Poor Installation
Improper installation of roofing materials can lead to a myriad of problems, including premature aging and failure of the roofing system. Issues stemming from poor installation include loose shingles, improper sealing, and inadequate underlayment.
Biological Growth
The presence of plants, algae, moss, fungi, or lichen on the roof often indicates moisture build-up. These biological growths can block drainage systems and, in extreme cases, damage the roof structure.
Structural Movement
Cracks, bulges, or valleys in the roof can indicate structural movement. These issues need to be addressed promptly to prevent further damage and ensure the roof’s stability.
Regular commercial roof inspections help identify these common issues early, allowing for timely repairs and maintenance.
This proactive approach can save you money in the long run and ensure the longevity and safety of your commercial property.

Types of Commercial Roofs We Inspect
At Markham Roofing, we have extensive experience inspecting a wide variety of commercial roofing systems in Toronto. Here are the main types of commercial roofs we inspect:
Built-Up Roofing (BUR) Membrane
Built-up roofing, commonly known as BUR, is a traditional roofing system that consists of multiple layers of bitumen and reinforcing fabrics. This type of roof is known for its durability and excellent waterproofing capabilities, making it ideal for flat or low-slope roofs.
Metal Roofing
Metal roofs are popular for their longevity and strength. We inspect various types of metal roofing materials, including galvanized steel, aluminum, copper, and zinc. Metal roofs are highly resistant to weather elements and can last for decades with proper maintenance.
Modified Bitumen Roofing
Modified bitumen roofs are composed of asphalt and a variety of modifiers and solvents. These roofs are typically installed in multiple layers and are known for their flexibility and resistance to extreme weather conditions. They are a great option for flat roofs that experience regular foot traffic.
Thermoset (EPDM) Roof Membrane
EPDM (ethylene propylene diene terpolymer) is a durable synthetic rubber roofing membrane widely used in low-slope commercial buildings. It offers excellent resistance to UV radiation, ozone, and weathering, making it a long-lasting roofing solution.
Thermoplastic (PVC & TPO) Roof Membrane
Thermoplastic roofing membranes, such as PVC (polyvinyl chloride) and TPO (thermoplastic polyolefin), are known for their durability and energy efficiency. These single-ply roofing systems are highly resistant to chemicals, punctures, and UV radiation, making them suitable for a variety of commercial applications.
Green Roofing Systems
Green roofs, also known as vegetative or garden roofs, are becoming increasingly popular for their environmental benefits. These roofs are covered with vegetation and soil, providing natural insulation, reducing stormwater runoff, and improving air quality. We inspect green roofs to ensure proper installation and maintenance.
Spray-On Roofing
Spray-on roofing systems involve applying a liquid coating that hardens into a seamless, waterproof layer. This type of roofing is ideal for complex roof shapes and provides excellent protection against leaks and weather damage.
Shingle Roofing
While more common in residential applications, shingle roofing can also be used in commercial settings. We inspect various types of shingles, including asphalt, wood, and slate, to ensure they are properly installed and maintained.
Our comprehensive inspections cover all these roofing types, ensuring that your commercial property remains protected and in optimal condition.
