Commercial Flat Roofing Systems
EPDM Roofing & Rubber Roofing Systems
Pros
- Low Maintenance: Minimal upkeep required over its lifespan
- Weather Resistant: Excellent performance in cold, wet climates like Grand Rapids
- Energy Efficient in Winter: Black membrane absorbs heat, reducing heating costs
- Cost-Effective Installation: Simple tools and fast application reduce labor costs
Cons
- Poor Puncture Resistance: Can be vulnerable to tears from foot traffic or debris
- UV Degradation Over Time: May shrink or crack with prolonged sun exposure if not maintained
- Limited Aesthetic Options: Typically available in black, which may not suit all building designs
TPO (Thermoplastic Polyolefin) Roofing
Pros
- Highly Reflective: White and tan membranes reduce cooling costs and meet CRRC and Energy Star® standards
- Affordable: Competitive pricing for materials and installation
- Quick Installation: Prefabricated accessories speed up the process
- Resistant to Mold & UV: Naturally resists algae, mold, and UV degradation
Cons
- Newer Technology: Less long-term performance data compared to EPDM or BUR
- Heat Welding Required: Installation requires specialized tools and trained installers
FleeceBACK® Roofing (TPO/EPDM Hybrid)
Pros
- Superior Durability: Reinforced fleece backing resists punctures, hail, and tears
- High Wind Resistance: Withstands uplift pressures up to 120 mph
- Energy Efficient: Available in reflective colors to reduce cooling loads
- Quiet Installation: Low-odor, low-noise application ideal for occupied buildings
Cons
- Higher Material Cost: Premium performance comes at a higher upfront price
- Requires Specialized Adhesives: Installation involves specific foam adhesives, increasing complexity
PVC (Polyvinyl Chloride) Roofing
Pros
- Chemical Resistant: Excellent for rooftops exposed to oils, grease, and industrial pollutants
- Energy Efficient: Reflective membranes reduce cooling costs and meet Energy Star® standards
- Heat-Welded Seams: Creates a watertight, strong bond that resists leaks
- Long Lifespan: Durable and low-maintenance over decades
Cons
- Higher Cost: More expensive than TPO or EPDM
- Brittle in Cold Weather: Can become less flexible in extreme cold, increasing risk of cracking
- Not Ideal for Heavy Foot Traffic: May require additional protection in high-use areas
Modified Bitumen Roofing
Pros
- Multi-Layer Protection: Multiple plies provide excellent waterproofing and durability
- Flexible & Tough: Asphalt with modifiers resists cracking and adapts to temperature swings
- Granule Surface: Protects against UV and weather damage
- Great for Foot Traffic: More resilient than single-ply systems in high-use areas
Cons
- Labor-Intensive Installation: Often requires torching or adhesives, increasing labor time
- Heat Absorption: Dark surface can raise building temperatures in summer
- Maintenance Required: Needs periodic inspections to maintain performance
Built-Up Roofing (BUR)
Pros
- Time-Tested: Over 100 years of proven performance on flat roofs
- Excellent Waterproofing: Multiple layers of asphalt and felt create a thick, durable barrier
- Affordable for Large Areas: Cost-effective for big commercial roofs
- Gravel Top Layer: Adds UV protection and fire resistance
Cons
- Heavy Weight: Requires strong structural support due to multiple layers
- Longer Install Time: Labor-intensive and weather-dependent process
- Ongoing Maintenance: Needs regular upkeep to prevent leaks and extend lifespan
