Commercial roofing is a critical part of any business. If your roof is not in good condition, it can lead to numerous problems for your business, including water damage, air infiltration, and structural damage. That’s why hiring a qualified commercial roofing contractor is essential to inspect and repair any problems. This post will outline some of the most common commercial roofing problems and how to identify and fix them.
What is Commercial Roofing?
Commercial roofing refers to installing, repairing, and maintaining roofing systems on commercial buildings such as offices, warehouses, and retail stores. These roofs typically have a larger surface area. They are subject to more wear and tear than residential roofs, making proper maintenance and repair essential for protecting the building and its occupants.
Importance of Proper Roofing for Commercial Buildings
Proper roofing is essential for commercial buildings as it plays a crucial role in protecting the building and its occupants, improving energy efficiency, preserving the value of the building, and meeting safety and regulatory codes.
Choosing a reputable commercial roofing contractor who can provide high-quality installation, repair, and maintenance services are essential. It is also important to note that many types of commercial roofing require regular maintenance, inspection, and repairs to ensure they perform as intended and last as long as possible.
Types of Commercial Roofing Systems

Several commercial roofing systems are available, each with its benefits and drawbacks. Some popular styles include:
- Flat Roofs are the most common type of commercial roofing characterized by a flat or nearly flat surface. They are typically used asphalt, modified bitumen, or single-ply membrane materials.
- Pitched Roofs: These are characterized by a sloping surface that allows water and snow to run off more easily. They are typically made of asphalt shingles, metal, or clay tiles.
- Green Roofs: These are roofs covered with vegetation, such as grasses, shrubs, or flowers. They are known to improve energy efficiency, reduce stormwater runoff, and improve the overall appearance of the building.
- TPO roofing: TPO stands for thermoplastic olefin. It is a type of roofing material that has been gaining popularity recently, particularly in the commercial roofing industry. TPO roofing is a type of single-ply roofing material, which means that it is a single layer of material laid down on the roof.
- Metal Roofing: Metal roofing is another popular commercial roofing option. Metal roofing can be made from various materials, including aluminum, steel, copper, and zinc. It is known for its durability, energy efficiency, and resistance to fire, wind, and other environmental factors.

Factors to consider when choosing a commercial roofing system
When choosing a commercial roofing system, there are several factors to consider:
- Climate and weather conditions: The roofing system chosen should be able to withstand the local weather conditions such as high winds, heavy rainfall, extreme heat or cold, and snow loads.
- Building usage and occupancy: The type of building use and occupancy will affect the roofing system choice. For example, a roofing system for a hospital should be more durable than a roofing system for a retail store.
- Building structure and design: The roofing system should complement the building structure and design. A flat roof system may be more appropriate for a modern building, while a sloped roof system may be more suitable for a traditional installation.
- Energy efficiency and sustainability: Building owners are increasingly opting for roofing systems that improve energy efficiency and reduce environmental impact. For example, green roofs and reflective roofing systems can reduce energy costs and lower the carbon footprint of the building.
- Budget and maintenance requirements: The cost of the roofing system and its maintenance should be considered. Some roofing systems may have higher upfront costs but lower long-term maintenance costs, while others may be less expensive initially but require more frequent repairs.
Installation and maintenance of commercial roofing systems
- Preparing the roof surface: The existing roof surface must be appropriately prepared before installing a new roofing system. This may involve removing old roofing materials, repairing damage to the underlying structure, and cleaning the surface.
- Installing the roofing system: The chosen method is installed according to the manufacturer’s instructions and local building codes. This typically involves laying down a layer of underlayment, attaching the roofing materials, and sealing any seams or joints.
- Inspections and repairs: Regular reviews of the roofing system are essential to identify potential issues and make repairs as needed. This may include patching leaks, replacing damaged shingles or tiles, and addressing other problems.
- Preventative maintenance: Regular preventive care can help extend the roofing system’s life and prevent costly repairs. This may include cleaning gutters, removing debris, and applying a protective coating to extend the roofing system’s life.
Benefits of Commercial Roofing
There are many benefits of commercial roofing, including the following:
- Protection: A properly installed and maintained roof protects the building and its occupants from the elements, such as rain, snow, and extreme temperatures.
- Energy efficiency: A properly insulated and sealed roof can help reduce heat loss and heat gain in the winter, leading to significant savings on heating and cooling costs. This is particularly important for large commercial buildings, which can have significant energy costs.
- Preservation of building value: A well-maintained roof can help to protect the overall value of the building. A damaged roof can negatively impact the appearance of the building, which can be a turn-off for potential customers or tenants and lead to costly repairs.
- Compliance with safety and regulatory codes: Commercial roofing often requires specific principles and standards to be met, such as fire codes and energy efficiency codes, which are in place to protect the safety and well-being of the building’s occupants and the surrounding community. A proper roofing system and installation can help to ensure that the facility meets these codes and standards, which is essential for the safety of the building’s occupants and the surrounding community.
- Durability and longevity: A properly installed and maintained commercial roof can last many years, providing an excellent return on investment.
- Aesthetics: A sound commercial roofing system not only provides protection and energy efficiency but also enhances the appearance of the building, which can improve the overall curb appeal and make it more attractive to customers and tenants.
- Low maintenance: Many modern commercial roofing systems require little maintenance and can last for many years.
Most Common Commercial Roofing Problems and How to Identify and Fix them
Some of the most common commercial roofing problems include:
- Leaks: Leaks are one of the most common problems with commercial roofs. Various factors, such as poor installation, damage to the roofing materials, or lack of proper maintenance, can cause them. To identify a leak, look for water stains on the ceiling or walls or evidence of water damage such as mold or mildew. To fix a leak, the source of the problem needs to be identified and repaired, which may involve patching a hole or replacing damaged materials.
- Ponding water: Ponding water is another common problem with commercial roofs. It occurs when water does not drain properly from the roof surface. This can lead to damage to the roofing materials and can also create an environment for mold and mildew to grow. To identify ponding water, look for standing water on the roof surface or evidence of water damage such as mold or mildew. To fix ponding water, the root cause of the problem needs to be identified and addressed, which may involve installing additional drainage systems or making changes to the roof’s slope.
- Damage from UV rays: Ultraviolet (UV) rays can cause damage to commercial roofing materials over time, leading to cracking, fading, and other forms of damage. To identify damage from UV rays, look for signs of fading or discoloration in the roofing materials or cracks in the surface. The affected materials may need to be replaced or repaired to fix damage from UV rays.
- Clogged gutters and downspouts can cause water to back up and damage the roof and the building. To identify clogged gutters and downspouts, look for water overflowing from the drains or evidence of water damage such as mold or mildew. To fix clogged gutters and downspouts, debris must be cleaned and cleared.
- Lack of insulation: Insulation is critical to maintaining energy efficiency in commercial buildings. Lack of insulation can lead to higher energy costs and make the building less comfortable. To identify a lack of insulation, look for drafts, uneven temperatures, and high energy bills. To fix a lack of insulation, additional insulation may need to be added to the building’s envelope
How Long Does A Commercial Roofing System Last?
The lifespan of a commercial roofing system can vary depending on the type of roofing system and the quality of installation and maintenance. Some roofing systems, such as metal roofing, can last up to 50 years or more with proper care, while others, such as asphalt shingles, may only last 15-20 years.
How often should a commercial roof be inspected?
It’s recommended that commercial roofs be inspected at least twice a year. Typically once in the spring and once in the fall. Additionally, after severe weather events, it is a good idea to perform an inspection.
What are the common causes of commercial roofing problems?
Common causes of commercial roofing problems include:
- Poor installation.
- Lack of proper maintenance.
- Exposure to harsh weather conditions.
- Damage caused by debris or vandalism.
How can leaks in a commercial roof be prevented?
Regular inspections and maintenance can achieve leak prevention in a commercial roof by using high-quality roofing materials and ensuring proper installation techniques are used. Regular cleaning of gutters and downspouts can also help prevent water damage.
A commercial roofing system protects a building and its occupants from the elements. However, more than the selection of the right roofing system is needed, it is also vital to ensure that the roofing system is installed and maintained by professional roofing contractors.
Proper installation and maintenance provide a long-lasting and effective commercial roofing system. Skipping or cutting corners during installation or maintenance can lead to leaks, deterioration, or even collapse, which can be costly and dangerous. Therefore, investing in professional installation and maintenance is a wise decision that will pay off in the long run.
