Selecting the right roofing system is one of the most important decisions a property owner can make. A commercial roof does more than cover your building—it protects assets, regulates energy use, and supports long-term structural performance. With so many options available today, choosing the right commercial roof involves more than just picking a material. It requires an understanding of your building’s design, your budget, local climate, and long-term goals.
At AGU Roofing & Solar, we help business owners throughout Central Florida navigate roofing choices confidently. This guide breaks down key considerations and compares top commercial roofing materials so you can make the most informed decision.
Why Choosing the Right Commercial Roof Matters
Not all commercial roofs are built the same. Different industries and structures have different requirements, which is why the roofing system must match your building’s use and environmental exposure.
Making the right roofing choice helps:
- Extend building lifespan
- Improve energy efficiency
- Reduce long-term maintenance costs
- Withstand weather conditions specific to your region (like Orlando’s heat and storms)
- Protect interior systems and operations
A well-chosen roof system not only safeguards your property—it’s also a long-term investment in your business’s performance and financial health.
Factors to Consider Before Choosing a Commercial Roof
Before looking at material options, consider the specific needs of your property. These key factors should guide your selection:
1. Roof Slope and Design
The slope (or pitch) of your roof will determine which materials are appropriate.
- Flat or low-slope roofs are common in commercial buildings and are ideal for membranes like TPO, EPDM, and modified bitumen.
- Steep-slope roofs may be better suited for metal panels or asphalt shingles in smaller commercial properties.
2. Budget and Long-Term Value
While budget is always a consideration, focusing on lifecycle costs (not just upfront pricing) is important. A slightly more expensive material could save you significantly over 20–30 years in repairs and energy bills.
3. Climate and Weather Conditions
In a warm, humid, and storm-prone environment like Central Florida, UV resistance, wind uplift performance, and moisture protection are essential.
The National Roofing Contractors Association emphasizes the importance of climate compatibility when selecting commercial roofing systems.
4. Building Usage and Foot Traffic
Roofs that support HVAC equipment, walkways, or frequent service visits need materials that can withstand foot traffic. Others may require better insulation or drainage systems depending on use.
5. Energy Efficiency Goals
Cool roofing materials can help lower cooling costs in hot climates. Some materials even qualify for tax incentives or rebates depending on your location.
Top Commercial Roofing Systems: Pros and Considerations
To help you decide, here’s an overview of the most common commercial roofing systems and how they stack up.
1. TPO (Thermoplastic Polyolefin)
Best for: Energy efficiency, low-slope roofs, hot climates
TPO is one of the most popular single-ply roofing membranes. It reflects UV rays, helping keep buildings cooler and reducing HVAC strain.
Pros:
- Highly reflective white surface for energy savings
- Affordable material and installation
- Heat-welded seams for watertight performance
- Mold and puncture-resistant
Considerations:
- Quality can vary by manufacturer—choose a trusted brand
- May degrade faster in extreme heat if not properly installed
TPO is widely regarded as one of the best roofing choices for commercial buildings in Florida due to its balance of price, performance, and efficiency.
2. EPDM (Ethylene Propylene Diene Monomer)
Best for: Durability, budget-conscious owners, long-term use
Known as “rubber roofing,” EPDM has been used for decades on flat commercial roofs. It’s especially known for its resistance to ozone and UV radiation.
Pros:
- Excellent weather resistance and flexibility
- Long lifespan (20–30 years)
- Cost-effective installation
- Low maintenance
Considerations:
- Typically black, which absorbs heat (white EPDM versions available)
- Not as reflective as TPO or PVC
- Adhesive seams may be more vulnerable over time than welded ones
3. Modified Bitumen
Best for: Durability under heavy traffic, traditional flat roofing
Modified bitumen is an asphalt-based system reinforced with layers of fiberglass or polyester. It’s often installed in multi-layer applications for enhanced performance.
Pros:
- Excellent for roofs with mechanical equipment
- Tough and puncture-resistant
- Proven performance in commercial settings
Considerations:
- Installation is more complex and labor-intensive
- May absorb heat if not coated with reflective surfacing
4. Metal Roofing
Best for: Sloped commercial roofs, long lifespan, aesthetics
While more common on steep-slope commercial buildings like retail stores or offices, metal roofing offers unmatched durability and style.
Pros:
- Lasts 40–70 years with minimal maintenance
- Fire and wind resistant
- Highly recyclable and eco-friendly
- Available in various colors and finishes
Considerations:
- Higher upfront cost
- May require additional insulation to reduce noise and regulate temperature
According to the Department of Energy, metal roofs coated with reflective finishes can significantly reduce building temperatures in sunny climates.
5. Built-Up Roofing (BUR)
Best for: Traditional multi-ply roofing, excellent waterproofing
BUR systems are made of alternating layers of bitumen and reinforcing fabrics. Finished with gravel or coatings, BUR offers excellent water resistance.
Pros:
- Time-tested performance
- Good UV protection and fire resistance
- Effective insulation and waterproofing
Considerations:
- Heavier than single-ply systems
- Longer installation process
- Not ideal for all building structures due to weight
How to Work with a Commercial Roofing Contractor
Once you’ve narrowed down your preferred roofing system, the next step is hiring the right contractor. At AGU Roofing & Solar, we know that proper installation is just as important as material selection.
Here’s what to look for:
- Experience with your preferred roofing system
- State licensing and insurance
- References from commercial clients
- Clear, written proposals with detailed scope of work
- Warranties on both labor and materials
For more tips on vetting contractors, the U.S. Small Business Administration provides helpful guidelines on selecting service providers for commercial projects.
Commercial Roof Upgrades That Add Long-Term Value
Beyond the main roofing material, consider these upgrades to maximize value:
- Cool Roof Coatings: Improve reflectivity and reduce cooling costs
- Insulation Upgrades: Meet or exceed energy codes and reduce heating/cooling loads
- Drainage Improvements: Prevent pooling and extend roof life
- Solar Integration: Offset energy costs and improve sustainability metrics
Each of these options can be tailored to your building’s structure and goals, and our team is happy to help you evaluate the potential benefits.
