What Type of Roof is Used for a Commercial Building?
If you’re interested in learning more about what type of roof is used for a commercial building, you’ve come to the right place!
Commercial buildings often present unique roofing challenges. Unlike the familiar sloped, shingled roofs seen on residential homes, commercial structures usually demand larger, flatter roofing solutions designed to withstand specific needs. The right commercial roof protects your building and its contents, providing a safeguard against the elements while contributing to energy efficiency and longevity.
Several different types of commercial roofing systems are available, each with its own advantages and best uses. In deciding on the perfect roof for your commercial building, you’ll need to consider factors like your local climate, the building’s function, and your budget. Let’s dive into the most popular options and what makes them a strong choice.
Flat Roofing Systems
Flat roofs are the most common choice for commercial establishments due to their practicality, affordability, and ease of maintenance. Here are the most popular flat roofing systems:
- Built-Up Roofing (BUR): These traditional systems consist of several layers of asphalt and reinforcing fabrics, topped with gravel or a reflective coating. BUR roofs offer durability and a relatively simple installation process, making them a cost-effective option.
- Modified Bitumen (Mod Bit): These asphalt-based systems are reinforced for flexibility and strength. Mod Bit roofs come in various application methods (torch down, self-adhesive, etc.), providing versatility for different projects.
- Single-Ply Membranes: These prefabricated rolls offer flexibility, high reflectivity, and excellent seam strength. Here are a few popular single-ply membrane options:
- TPO (Thermoplastic Polyolefin): Known for its durability, energy efficiency, and ease of installation.
- PVC (Polyvinyl Chloride): Valued for its superior resistance to chemicals, fire, and high winds.
- EPDM (Ethylene Propylene Diene Terpolymer): A synthetic rubber option with flexibility and excellent resistance to expansion and contraction caused by temperature fluctuations.

Why Flat Roofs Are Popular for Commercial Buildings
- Cost-Effectiveness: Flat roofing systems are generally more affordable to install compared to sloped roofs.
- HVAC Unit Space: Flat roofs provide ample space for accommodating HVAC systems, solar panels, or other rooftop equipment, helping keep essential utilities out of sight.
- Ease of Maintenance: Access to flat roofs is simpler and safer, facilitating routine maintenance, inspections, and any necessary repairs.
Sloped Commercial Roofs
Although less common, commercial buildings may sometimes have sloped roofs. Here are a few options:
- Metal Roofing: Metal roofs, such as standing seam panels, offer long-term durability, resistance to the elements, and energy efficiency advantages. They can also add a modern aesthetic to your building.
- Shingles: While primarily used on residential properties, asphalt shingles can also be suitable for smaller commercial structures with steeper roof slopes.
Choosing the Best Commercial Roofing System: Things to Consider
Choosing the right roof for your commercial building depends on several factors:
- Climate and Weather: Choose a roofing system that can withstand your local weather conditions, including heavy rain, snowfall, high winds, and extreme temperatures.
- Budget: Consider the initial installation costs as well as the expected lifespan and long-term maintenance requirements of different roofing systems.
- Building Use: The purpose of your commercial building can influence your roofing choice. Certain roofing materials are better suited for industrial operations or environments with exposure to specific chemicals.
- Energy Efficiency Goals: Energy-efficient roofing choices help reduce operational costs. Look for ENERGY STAR® certified roof coatings or reflective single-ply membranes to minimize heat absorption.
