1. TPO (Thermoplastic Polyolefin)
What is TPO?
TPO is a single-ply roofing membrane that has become the most popular choice for commercial flat roofs in the past 20 years. It's heat-welded at the seams, creating watertight bonds stronger than the membrane itself.
The white or light-gray surface reflects sunlight, reducing cooling costs significantly—a major advantage in Fort Worth's scorching summers where roof surface temperatures can exceed 170°F.
✓ Advantages
- Energy efficient: Reflects 80%+ of UV rays, reduces cooling costs 20-30%
- Heat-welded seams: Superior leak resistance vs. adhesive systems
- Chemical resistant: Handles grease, oils common in restaurant/industrial settings
- Flexible in cold: Doesn't crack in rare Texas freezes
- Relatively affordable: Lower cost than metal, good ROI
✗ Disadvantages
- Puncture vulnerability: Can be damaged by hail, falling branches, or foot traffic
- Shorter lifespan: 15-25 years vs. 30+ for metal or BUR
- Seam quality critical: Poor installation leads to leaks; requires experienced installer
- UV degradation: Quality varies by manufacturer; cheap TPO fails early

2. EPDM (Rubber Roofing)
What is EPDM?
EPDM (ethylene propylene diene monomer) is a synthetic rubber membrane that has been the workhorse of commercial roofing since the 1960s. It's available in black or white, with black being more common due to lower cost.
EPDM is known for proven performance, straightforward installation, and excellent resistance to ozone, UV radiation, and temperature extremes. It's the "tried and true" option many building owners trust.
✓ Advantages
- Proven longevity: 20-30 years with proper maintenance; some roofs exceed 40 years
- Budget-friendly: Lower material costs than TPO or metal
- Easy to repair: Patches adhere well; repairs can be DIY-friendly
- Flexible: Handles temperature swings from -40°F to 300°F
- Environmentally friendly: Recyclable at end of life
✗ Disadvantages
- Black absorbs heat: Increases cooling costs 15-25% vs. white TPO
- Seam concerns: Adhesive/tape seams weaker than heat-welded (white EPDM must be taped)
- Puncture-prone: Vulnerable to sharp objects, hail damage
- Shrinkage: Can shrink over time, pulling at seams and fasteners

3. Modified Bitumen
What is Modified Bitumen?
Modified bitumen (often called "mod bit") is an evolution of traditional built-up roofing. It uses asphalt modified with rubber or plastic polymers, applied in multi-layer systems with reinforced fabric.
Installation methods include torch-applied (heat-welded), self-adhering (peel-and-stick), or cold-applied adhesives. Torch-applied creates the strongest bonds but requires experienced crews and fire safety measures.
✓ Advantages
- Multi-layer protection: Redundancy built-in; puncture less critical
- Handles foot traffic: Durable surface for rooftop equipment maintenance
- Flexible installation: Torch, cold-applied, or self-adhering options
- Good in extreme temps: Polymers prevent cracking in cold, softening in heat
- Granulated surface: Protects from UV, provides slip resistance
✗ Disadvantages
- Torch application risks: Fire hazard during installation requires permits/monitoring
- Dark color: Absorbs heat unless white cap sheet used (adds cost)
- Shorter lifespan: 15-20 years, requiring more frequent replacement
- Seam maintenance: Laps need periodic inspection and resealing

4. Built-Up Roofing (BUR)
What is BUR?
Built-Up Roofing (BUR) is the original "tar and gravel" roof that has protected commercial buildings for over 100 years. It consists of alternating layers of bitumen (asphalt or coal tar) and reinforcing fabric, topped with gravel or mineral surfacing.
Typically 3-5 layers thick, BUR creates a seamless, monolithic membrane. The gravel surface protects from UV radiation, provides fire resistance, and allows foot traffic without damage—critical for rooftop HVAC maintenance.
✓ Advantages
- Exceptional durability: 20-30 years; some well-maintained roofs last 40+ years
- Heavy traffic capable: Gravel surface handles equipment, foot traffic without damage
- Redundancy: Multiple layers mean single puncture unlikely to cause leak
- Fire resistant: Gravel provides Class A fire rating
- Cost-effective longevity: Low cost per year of service
✗ Disadvantages
- Heavy weight: 5-7 lbs/sq ft requires strong structural support
- Installation odor: Hot asphalt smell can disrupt business operations
- Leak detection difficult: Water can travel between layers before appearing inside
- Dark surface: Absorbs heat unless white gravel used (less common, more expensive)
- Messy removal: Tear-off is labor-intensive and expensive

5. Metal Roofing
What is Commercial Metal Roofing?
Commercial metal roofing includes standing seam systems (concealed fasteners), R-panel/corrugated systems (exposed fasteners), and structural panels. Materials include steel (most common), aluminum (coastal areas), and zinc/copper (premium).
Standing seam is the premium choice for low-slope commercial buildings: interlocking panels create a watertight barrier without penetrating fasteners, and the metal's expansion/contraction is accommodated by clips that allow movement.
✓ Advantages
- Exceptional lifespan: 30-50 years for steel, 50+ for aluminum/zinc
- Superior energy efficiency: Reflective coatings reduce cooling costs 25-40%
- Weather resistance: Withstands 140+ mph winds, hail, fire (Class A rating)
- Low maintenance: Minimal annual upkeep beyond inspections
- Recyclable: 100% recyclable at end of life; often contains recycled content
- Lightweight: 1-3 lbs/sq ft vs. 5-7 for BUR
✗ Disadvantages
- High upfront cost: 50-100% more than TPO or EPDM initially
- Installation expertise required: Fewer qualified installers; errors costly
- Noise: Rain/hail can be louder without proper insulation
- Denting: Large hail can dent panels (cosmetic, not structural)
- Thermal movement: Expansion/contraction requires proper clip systems

Warranty Options Compared
Critical Warranty Considerations
Commercial roofing warranties are complex. Understanding the difference between material warranties (manufacturer defects) and workmanship warranties (installation quality) is essential. Most leaks result from installation errors, not material failure.
| System | Material Warranty | Workmanship | Notes |
|---|---|---|---|
| TPO | 10-20 years Prorated after 5-10 yrs | 2-10 years Contractor-dependent | Manufacturer quality varies; choose reputable brands (GAF, Carlisle, Firestone) |
| EPDM | 10-25 years Prorated after 10 yrs | 2-10 years | Proven track record; manufacturers confident in long-term performance |
| Mod Bit | 10-20 years Often prorated | 2-5 years | Shorter workmanship warranties; installation skill critical for torch-applied |
| BUR | 10-20 years System warranty | 5-10 years | Longer workmanship coverage typical due to multi-layer redundancy |
| Metal | 20-50 years Paint 20-30 yrs | 2-10 years | Substrate warranties longer than paint/finish; choose Kynar 500 coatings |
💡 Pro Tips for Warranty Protection
- Get it in writing: Ensure both material and workmanship warranties are documented in contract
- Annual inspections: Many warranties require professional inspections to remain valid
- Transferability: If you sell your building, check if warranty can transfer to new owner
- Exclusions matter: Wind speed limits, ponding water, and improper drainage often void warranties
- Prorated vs. non-prorated: Non-prorated coverage (even if shorter) can be more valuable
Minimal Business Disruption Strategies
Roof replacement is a major project, but with proper planning, you can minimize downtime, maintain employee comfort, and keep customers happy. Here's how:
1. Phased Installation
For large buildings, work in sections rather than tearing off the entire roof at once. This approach:
- ✓ Keeps most of building operational during construction
- ✓ Limits exposed areas if unexpected weather arrives
- ✓ Allows HVAC systems to continue functioning
- ✓ Reduces noise impact to specific zones
Timeline impact: Adds 1-2 weeks but worth it for 24/7 operations
2. Weekend/Night Installation
Schedule work outside business hours for retail, offices, or customer-facing businesses:
- ✓ Zero customer disruption during business hours
- ✓ Employees work in normal conditions
- ✓ Noise/activity happens when building empty
- ✓ Parking areas remain accessible
Cost impact: 10-20% premium for off-hours labor, but sales/productivity maintained
3. Recover/Re-Cover Systems
Install new roofing over existing (when structural capacity allows):
- ✓ No tear-off means no interior exposure risk
- ✓ Faster installation (50% quicker in many cases)
- ✓ Less debris, cleaner site, quieter process
- ✓ Added insulation can improve energy efficiency
Limitation: Building codes often limit to 2 roof layers total; structural review required
4. Temporary Weather Protection
Professional contractors use protective measures during work:
- ✓ Tarps and temporary covers protect exposed areas overnight
- ✓ Weather monitoring ensures work stops before rain
- ✓ Interior protection (plastic sheeting, catch basins) for sensitive areas
- ✓ Equipment staged to allow rapid covering if weather changes
Fort Worth consideration: Summer afternoon storms require vigilant monitoring
📋 Pre-Project Checklist for Business Continuity
- ☑️ Notify employees 2-3 weeks in advance
- ☑️ Alert customers if retail/service business
- ☑️ Move sensitive equipment away from exterior walls
- ☑️ Cover/protect inventory in storage areas
- ☑️ Designate parking for contractor vehicles
- ☑️ Schedule important meetings off-site during loud phases
- ☑️ Coordinate with neighboring businesses if shared building
- ☑️ Plan alternative deliveries/loading dock access
- ☑️ Test backup power systems before work begins
- ☑️ Document pre-existing conditions with photos
2025 Commercial Roofing Trends
🌿 Green Roofs & Sustainability
Vegetative roofing systems (gardens on roofs) are growing in popularity for urban Fort Worth businesses. Benefits include stormwater management (reducing runoff by 50-90%), exceptional insulation (R-value 10-20 higher), and employee wellness spaces.
Cost: $10-$25/sq ft installed | ROI: 15-20 years through energy savings + water credits

Frequently Asked Questions
How long does commercial roof installation take?
Timeline varies by system and building size. For a typical 10,000 sq ft building: TPO/EPDM: 3-5 days for tear-off and install, Modified bitumen: 4-6 days, BUR: 5-7 days due to multiple layers, and Metal: 7-14 days for standing seam precision work. Larger buildings (50,000+ sq ft) take 2-4 weeks. Phased installations add 1-2 weeks but minimize disruption.
Can we install a new roof over the existing one?
Sometimes yes, but it depends on three factors: 1) Structural capacity—the building must support the additional weight (typically 2-5 lbs/sq ft); 2) Code compliance—most jurisdictions limit to 2 total roof layers; 3) Existing condition—the old roof must be relatively flat (no major warping or wet insulation). A structural engineer can assess feasibility. Benefits include faster installation and no interior exposure. Costs are 10-20% lower than tear-off, but you sacrifice the opportunity to inspect/repair the deck.
What maintenance do commercial roofs need annually?
All systems benefit from biannual professional inspections (spring and fall) costing $300-$800 each. Key maintenance includes: clearing drains/gutters to prevent ponding (the #1 commercial roof killer), checking/resealing flashing around HVAC units and penetrations, removing debris that can puncture membranes, and repairing small issues before they spread. Budget $800-$1,600/year for routine maintenance. Neglecting this can void warranties and cut roof lifespan by 30-50%.
Are there tax benefits or rebates for commercial roofing?
Yes, several programs available in 2025: Section 179D federal deduction allows up to $5.00/sq ft for energy-efficient roofing that reduces building energy use 25%+ (cool roofs, metal often qualify); Oncor rebates (Fort Worth's utility) offer $0.25-$0.50/sq ft for high-albedo (reflective) roofs; Depreciation allows 39-year straight-line depreciation for commercial buildings, but qualified improvement property may be eligible for bonus depreciation. Consult a CPA familiar with commercial property to maximize benefits—potential savings of $5,000-$20,000 on a 10,000 sq ft project.
How do I know when it's time to replace vs. repair?
Replace if: Roof is within 3-5 years of expected lifespan end, damage covers 25%+ of surface area, recurring leaks despite repairs, widespread membrane deterioration, or wet insulation (loses 50-90% R-value). Repair if: Roof is less than half its expected life, damage is isolated (one section), it's a single-event issue (storm damage), and repair costs less than 20-25% of replacement cost. Get professional assessment—a $500 inspection can save you from premature $60,000 replacement or guide you away from throwing good money after bad on a failing roof.
