Common Types of Roofs for Commercial Roofing
Flat Roofs
Flat roofs are a popular choice for commercial buildings, especially for low-slope designs. They have lots of advantages, like providing extra space for HVAC systems, solar panels, or even outdoor seating areas. But they need effective drainage systems to prevent water from building up, which can lead to leaks and long-term structural damage.
Advantages:
- Cost-effective and easy to install
- Maximizes usable space
- Ideal for commercial buildings with HVAC or rooftop equipment
Disadvantages:
- Prone to water pooling if not installed correctly
- Requires regular maintenance to prevent leaks
Metal Roofs
Metal roofs are built to last, which makes them a popular choice for commercial buildings in areas prone to harsh weather. Available in materials like steel, aluminum, and copper, metal roofs offer excellent resistance to wind, hail, and fire.
Advantages:
- Extremely durable and weather-resistant
- Reflects UV rays, reducing energy costs
- Low maintenance and long-lasting
Disadvantages:
- Higher upfront cost compared to other materials
- Can be noisy during heavy rain or hailstorms
Single-Ply Membranes
Single-ply membrane roofing systems—like TPO (Thermoplastic Olefin), EPDM (Ethylene Propylene Diene Monomer), and PVC (Polyvinyl Chloride)—are widely used for flat commercial roofs. They’re easy to install, energy-efficient, and resistant to chemicals, making them ideal for industrial buildings.
Advantages:
- Lightweight and easy to install
- Resistant to UV rays and weathering
- Energy-efficient, reducing heating and cooling costs
Disadvantages:
- Can be punctured if not properly maintained
- Installation requires professional expertise to ensure seams are secure
Built-Up Roofs (BUR)
BUR is a traditional commercial roofing system made up of several layers of bitumen (asphalt or tar) and reinforcing fabrics. These roofs often have a gravel top for extra durability and UV protection.
Advantages:
- Provides excellent waterproofing
- Long-lasting and durable
- Great for larger commercial properties
Disadvantages:
- Heavier than other roofing materials, so it needs a reinforced structure
- Installation can be messy and time-consuming
Modified Bitumen
Modified bitumen is a great combo of ease and durability—easy to install like single-ply systems, but durable like BUR. This material contains asphalt that’s been modified with polymers to give it extra flexibility and strength.
Advantages:
- Durable and resistant to weather elements
- Easy to install with heat-welded seams
- Good for both low-slope and flat roofs
Disadvantages:
- Needs professional installation to avoid seams failing
- Requires more frequent maintenance than with other systems
Green Roofs
Green roofs—also called living roofs—are roofs with a waterproof membrane on which you grow plants. They have lots of benefits, like better insulation, stormwater management, and air quality. The downside is that they require more upkeep than traditional roofing systems.
Advantages:
- Environmentally friendly and energy-efficient
- Great insulation and stormwater management
- Aesthetic appeal with potential for rooftop gardens
Disadvantages:
- Higher initial installation costs
- Needs ongoing maintenance and structural support
Factors to Consider When Choosing a Commercial Roof
Local Climate
The weather in your region plays a big role in deciding which roofing material will perform best. For example, areas with heavy snowfall may benefit from metal roofs due to their snow-shedding properties, while areas with intense UV exposure may require reflective materials to keep the building cool.
Energy Efficiency
With rising energy costs, businesses are looking for roofs that can help cut heating and cooling costs. Materials that reflect UV rays or provide insulation can significantly lower energy bills over time.
Roof Structure & Design
The type of commercial roof you choose must match the structural capabilities of your building. Flat roofs, for instance, may be more suitable for certain designs, while other structures may need sloped or pitched roofs.
Budget & Long-Term Costs
Upfront costs vary greatly depending on the roofing material chosen. While materials like metal and green roofs may cost more upfront, they can save you money in the long run thanks to their durability, energy efficiency, and minimal maintenance needs.
Roof Maintenance Tips for Commercial Property Owners
- Schedule Regular Inspections: Have your roof professionally inspected at least twice a year. Inspections are especially important after severe weather events.
- Clean Gutters & Drains: Make sure gutters and drains are free of debris to allow proper water flow, preventing water damage and leaks.
- Address Issues Promptly: Small issues, such as loose shingles or minor leaks, can turn into expensive repairs if not addressed immediately. Regularly check for signs of wear and act quickly.
- Trim Overhanging Trees: Branches from nearby trees can scrape the roof surface or fall during storms, causing damage. Keep trees trimmed to prevent this.
- Check Flashing and Seals: Flashing around vents, chimneys, and skylights can wear out over time. Make sure these areas are properly sealed to prevent water from seeping in.
Find the Best Roof for Your Business
When choosing the roof for your commercial property, there’s more to consider than just the type of roof or material used. Each roofing system has its own features that make it better for certain types of buildings, climates, and purposes.
