Commercial Roofing Systems: Choosing the Right Solution for Your Building
When it comes to commercial roofing, one size does not fit all. Each building has unique structural needs, environmental challenges, and budgetary considerations. At Kosarek Construction, we specialize in guiding property owners, developers, and facility managers through the process of choosing the right roofing system to ensure long-term performance and value.
Here’s what you need to know to make an informed decision for your commercial property.
Understanding Commercial Roofing Systems
Commercial roofs differ from residential roofs in both structure and materials. Most commercial roofs are flat or low-sloped, requiring special membrane systems designed to handle pooling water, temperature shifts, and rooftop equipment.
The most common commercial roofing systems include:
- TPO (Thermoplastic Polyolefin) Roofing
Best for: Energy efficiency, lightweight construction, and cost savings.
Advantages:
- Highly reflective surface reduces cooling costs
- Resistant to UV rays, punctures, and chemical exposure
- Welded seams provide watertight protection
- Lower installation and maintenance costs
Drawbacks:
- Requires skilled installation to avoid seam failure
- May not perform as well in extremely cold climates
- PVC (Polyvinyl Chloride) Roofing
Best for: Restaurants, industrial facilities, and buildings exposed to chemicals or grease.
Advantages:
- Exceptional chemical and grease resistance
- Strong, heat-welded seams
- High reflectivity for energy savings
- Long-lasting and low maintenance
Drawbacks:
- Higher material cost than TPO
- Can become brittle over time if exposed to extreme cold
- EPDM (Ethylene Propylene Diene Monomer)
Best for: Budget-conscious owners and large buildings needing long-term protection.
Advantages:
- Low installation cost
- Proven durability (lifespan of 20–30 years)
- UV and ozone resistant
- Flexible in cold weather
Drawbacks:
- Typically black, which can absorb heat
- Seams are glued, not welded, which may weaken over time
- Aesthetic limitations compared to other systems
- Silicone Roof Coatings
Best for: Extending the life of existing roofs or improving waterproofing without a full replacement.
Advantages:
- Excellent waterproofing and ponding resistance
- Reflective white surface lowers energy use
- Quick to apply over existing roofs
- Minimal maintenance needed
Drawbacks:
- Not ideal for all roof conditions
- Higher upfront cost per square foot than other coatings
- Requires professional surface prep and application
- BUR (Built-Up Roofing)
Best for: Industrial buildings and flat roofs needing multi-layer protection.
Advantages:
- Multiple layers increase durability and insulation
- Excellent fire and impact resistance
- Time-tested with over 100 years of use
Drawbacks:
- Heavier than most roofing systems
- Requires longer installation times
- May release fumes during installation
