Types of Commercial Flat Roofing

Built-Up Roofing (BUR)

Built-Up Roofing (BUR) is a traditional and popular choice for commercial flat roofs. This type of roofing system consists of multiple layers of bitumen and ply sheets that are bonded together with hot asphalt or coal tar pitch. BUR roofs offer excellent durability and can withstand heavy foot traffic, making them suitable for commercial buildings with rooftop equipment or frequent maintenance needs.

Modified Bitumen (Mod-Bit)

Modified Bitumen, also known as Mod-Bit, is a single-ply roofing system that combines asphalt with modifiers to enhance its performance and durability. Mod-Bit roofs are typically installed using heat-welded seams or cold adhesive, providing a strong and long-lasting solution for commercial flat roofs. This roofing material is resistant to weathering, UV radiation, and thermal cycling, making it ideal for areas with extreme temperatures.


Ethylene Propylene Diene Monomer (EPDM) is a synthetic rubber roofing membrane commonly used for commercial flat roofs. EPDM roofs are durable, lightweight, and highly resistant to UV radiation, ozone, and weathering. The installation of EPDM roofing involves either fully adhering the membrane to the roof substrate or mechanically attaching it with fasteners and plates. EPDM roofs provide excellent waterproofing and are known for their long lifespan.


Thermoplastic Olefin (TPO) is a single-ply roofing membrane made of a blend of rubber and plastic. TPO roofs are heat-welded together to create a watertight seal, ensuring superior performance and durability. This roofing material is highly resistant to UV radiation, chemicals, and punctures. TPO roofs are energy-efficient and reflect heat, helping to reduce cooling costs for commercial buildings.


Polyvinyl Chloride (PVC) is another thermoplastic roofing membrane commonly used in commercial flat roofing systems. PVC roofs are renowned for their durability, flexibility, and fire resistance. The seams of PVC membranes are heat-welded or chemically bonded for added strength and watertightness. PVC roofs offer excellent resistance to chemicals, UV radiation, and weathering, making them suitable for various commercial applications.

Metal Roofing

Metal roofing systems, such as standing seam roofs or metal panels, are a popular choice for commercial flat roofs. Metal roofs are durable, lightweight, and provide excellent protection against extreme weather conditions. They are available in various metal types, including steel, aluminum, and copper. Metal roofs are resistant to fire, pests, and rot, and often come with long warranties, making them a cost-effective choice for commercial buildings.

Benefits of Commercial Flat Roofing


Commercial flat roofing systems offer cost-effective solutions, both in terms of installation and long-term maintenance. Flat roofs require fewer materials than pitched roofs, reducing initial costs. Additionally, the ease of maintenance and accessibility of flat roofs make repairs and inspections more affordable, saving businesses on maintenance expenses in the long run.


Commercial flat roofing systems are highly versatile, accommodating a wide range of designs and architectural styles. Flat roofs can be customized to suit specific building needs, allowing businesses to optimize their roof space for various purposes, such as rooftop gardens, solar panels, HVAC equipment installations, and more.

Easy Maintenance

Maintaining a commercial flat roof is relatively easier compared to other roof types. The accessibility and flat surface of these roofs make inspections and repairs more convenient. Regular maintenance tasks, such as cleaning gutters, removing debris, and inspecting for leaks or damage, can be performed quickly and efficiently.

Extended Lifespan

Properly installed and maintained commercial flat roofing systems can have a lifespan of 25 to 40 years or even longer, depending on the material used. This extended lifespan saves businesses from frequent roof replacement costs, providing long-term reliability and peace of mind.

Energy Efficiency

Commercial flat roofing systems can contribute to energy efficiency by reducing heating and cooling costs. Reflective roofing materials, such as TPO and PVC, can reflect sunlight, minimizing heat absorption and reducing the need for excessive cooling. Additionally, flat roofs can accommodate the installation of solar panels, further enhancing energy efficiency and potentially providing businesses with renewable energy sources.

Professional Inspection and Assessment

Thorough Examination

A professional inspection of a commercial flat roof involves a thorough examination of every component to ensure its structural integrity and identify any existing or potential issues. This examination includes inspecting the roof surface, flashings, seams, drainage systems, and any other elements that may affect the roof’s performance.

Identification of Issues

During the inspection, a trained professional will identify any issues or areas of concern, such as leaks, ponding water, damaged flashings, or deteriorating membrane. These issues are documented to provide an accurate assessment of the roof’s condition and determine the necessary repairs or maintenance actions.

Detailed Report

After the inspection, a detailed report is prepared, outlining the findings of the examination and identifying any immediate or potential problems. The report provides businesses with a comprehensive understanding of the roof’s condition and serves as a valuable reference for planning repairs, maintenance, or roof replacement.


Based on the inspection findings, the professional roofing inspector will provide recommendations for the necessary repairs, maintenance, or improvements needed to ensure the roof’s longevity and performance. These recommendations are tailored to the specific needs of the commercial building and take into account factors such as budget, timeline, and long-term goals.

Roof Repair and Restoration

Leak Detection and Repair

Leak detection and repair is a crucial aspect of maintaining a commercial flat roof. Professional roofing services employ state-of-the-art technology and techniques to accurately locate and repair leaks, preventing further damage to the building and its contents. Repair methods may include patching damaged areas, sealing flashings, or replacing deteriorated roofing components.

Ponding Water Solutions

Ponding water can occur on flat roofs due to improper drainage systems or structural issues. Left unaddressed, ponding water can lead to roof deterioration, leaks, and even structural damage. Professional roofers can provide solutions to correct ponding water issues, such as improving roof slope, installing additional drains, or implementing tapered insulation systems.

Flashing and Seam Repairs

Flashing and seams play a crucial role in maintaining the integrity and waterproofing of a commercial flat roof. Over time, flashings and seams can deteriorate due to weathering, thermal expansion and contraction, or damage. Professional roofers are skilled in repairing or replacing damaged flashings and seams, ensuring a watertight and durable roofing system.

Roof Coating Application

Roof coatings can provide added protection and extend the lifespan of a commercial flat roof. Professional roofers apply high-quality coatings that create a seamless, waterproof barrier on the roof surface. These coatings can enhance UV resistance, reflect sunlight, and improve energy efficiency. Roof coating application is an effective and cost-efficient way to restore and prolong the life of a flat roof.

New Roof Installation

Customized Design and Planning

When installing a new commercial flat roof, a professional roofing company will work closely with the business to understand its specific needs and requirements. They will assess factors such as building size, function, local climate, and budget to develop a customized design and installation plan that meets the client’s goals and ensures optimal performance.

Quality Material Selection

Professional roofing companies have access to a wide range of high-quality roofing materials suitable for commercial flat roofs. They will help businesses choose the best material for their specific needs based on factors such as durability, energy efficiency, aesthetics, and budget. The selected materials will be of the utmost quality to ensure a long-lasting and reliable roofing system.

Efficient Installation Process

Professional installation of a commercial flat roof involves using industry-standard techniques and the latest equipment. Experienced roofing teams work efficiently while adhering to safety standards, ensuring that the installation is completed on time and with minimal disruption to the business operation. Thorough quality checks are performed throughout the installation process to guarantee a flawless result.

Ongoing Maintenance

Once the new commercial flat roof is installed, a professional roofing company can provide ongoing maintenance services to keep the roof in optimal condition. Regular inspections, cleaning, and minor repairs are essential to prevent major issues and prolong the lifespan of the roof. By partnering with a roofing company for ongoing maintenance, businesses can ensure the continued performance and longevity of their investment.

Preventive Roof Maintenance

Regular Inspections

Regular inspections are an integral part of preventive roof maintenance. Professional roofers conduct inspections at scheduled intervals to assess the condition of the roof, identify any emerging issues, and perform necessary maintenance actions promptly. Through regular inspections, potential problems can be detected and resolved before they escalate into major and costly repairs.

Debris Removal

Accumulated debris, such as leaves, branches, or dirt, can cause ponding water, clog drains, and damage the roofing membrane. Professional roofing services include regular debris removal to ensure proper water drainage and prevent roof damage. By keeping the roof surface clear of debris, businesses can maintain the integrity and performance of their flat roof.

Gutter Cleaning

Clean and functioning gutters are crucial for the proper drainage of a commercial flat roof. Clogged or damaged gutters can lead to water accumulation and subsequent roof damage. Professional roofers provide gutter cleaning services, removing any blockages and ensuring that the gutters are free-flowing and able to direct water away from the building.

Sealant Application

Sealants, such as silicone or elastomeric coatings, can be applied to vulnerable areas of a commercial flat roof to enhance waterproofing and protect against leaks.

Roof Surface Cleaning

Regular cleaning of the roof surface not only enhances its appearance but also helps maintain its performance and longevity. Professional roofers utilize appropriate cleaning techniques and materials to remove dirt, grime, and algae growth from the roof surface. By keeping the roof clean, businesses can prevent staining, deterioration, and potential damage.

Emergency Roofing Services

24/7 Emergency Response

When emergencies such as severe storms, fallen trees, or accidents cause damage to a commercial flat roof, prompt action is crucial. Professional roofing companies offer 24/7 emergency response services, ensuring that businesses receive immediate assistance to mitigate further damage and secure the premises.

Temporary Repairs

In emergency situations, temporary repairs are often necessary to prevent further damage and ensure the safety of the building and its occupants. Professional roofers provide temporary solutions, such as patching damaged areas or securing loose components, until permanent repairs can be completed.

Water Damage Mitigation

Water damage resulting from roof leaks can have severe consequences, including structural damage and mold growth. Professional roofing services promptly address roof leaks and provide water damage mitigation, including drying affected areas, disinfection, and preventing further moisture intrusion.

Permanent Solutions

Once the immediate emergency is addressed, professional roofers work closely with businesses to develop and implement permanent repair solutions. These solutions are tailored to the extent and nature of the damage and may include roof repairs, replacement of damaged components, or even complete roof replacement. The goal is to restore the roof to its pre-damage condition and ensure long-term protection.

Roof Upgrades and Enhancements

Insulation Enhancement

Improving insulation is an upgrade that can significantly enhance the energy efficiency and comfort of a commercial building.

Professional roofing companies can assess the roof’s suitability for solar panel installation, design the layout, and assist with the integration and connection of the solar panel system.

Roof Warranty and Insurance Claims

Warranty Coverage Explanation

Professional roofing companies provide detailed explanations of the warranty coverage for new roof installations or roof repairs. They ensure that businesses understand the terms and conditions of the warranty, including the coverage period, specific limitations, and any required maintenance or inspection requirements. This helps businesses make informed decisions and confidently proceed with their roofing projects.

Assistance with Insurance Claims

When damage occurs to a commercial flat roof due to covered events, such as storms or accidents, professional roofing companies can assist businesses with the insurance claims process. They gather the necessary documentation, provide accurate assessments of the damage, and communicate with the insurance company to ensure a smooth and successful claims process.

Claims Process Guidance

Navigating the insurance claims process can be complex and time-consuming for businesses. Professional roofing companies offer guidance and support throughout the claims process, providing expert advice, documentation assistance, and ensuring that businesses receive fair and appropriate compensation for their roof damage.

Choosing a Reliable Commercial Flat Roofing Company

Experience and Expertise

When selecting a commercial flat roofing company, businesses should consider the company’s experience and expertise in the industry. Look for companies with a proven track record of successful roof installations, repairs, and maintenance. Experienced roofing professionals have the necessary knowledge, skills, and resources to provide high-quality and reliable services.

Licensed and Insured

It is essential to choose a roofing company that is licensed and insured. Licensing ensures that the company meets all legal requirements and has met certain professional standards. Insurance coverage protects both the roofing company and the business from any liability in case of accidents or property damage during the roofing project.

Positive Customer Reviews

Reading customer reviews and testimonials can provide valuable insights into the reputation and quality of service of a commercial flat roofing company. Look for companies with positive reviews, satisfied customers, and a strong reputation for delivering excellent results.

Transparent Pricing

Transparency in pricing is crucial when choosing a roofing company. Look for companies that provide detailed and clear estimates or quotes for their services. Avoid companies that provide vague or overly low-cost estimates, as they may engage in unethical practices or deliver subpar results.

Satisfaction Guarantee

A reliable commercial flat roofing company stands behind its work and offers a satisfaction guarantee. They should be willing to address any concerns or issues that arise after the completion of the roofing project. A satisfaction guarantee ensures that the business receives the quality and service they expect and provides peace of mind throughout the entire roofing process.
