Frequently Asked Questions

TPO (Thermoplastic Polyolefin) is a single-ply membrane roofing system known for being cost-effective, energy-efficient, and lightweight. It's heat-welded at the seams, providing excellent waterproofing for flat or low-slope commercial roofs.

PVC (Polyvinyl Chloride) is a premium single-ply membrane with superior chemical resistance and fire performance. It's ideal for restaurants, industrial facilities, or buildings with rooftop equipment that may leak oils or chemicals.

Metal roofing (standing seam or corrugated) offers exceptional longevity (40–70 years), superior wind resistance, and low maintenance. It works for both commercial warehouses and residential properties seeking durability and modern aesthetics.

Bottom line: TPO is budget-friendly, PVC handles harsh environments, and metal roofing delivers unmatched lifespan.

It depends on your building type, budget, and performance needs:

• TPO roofing is the most popular choice for commercial buildings due to its balance of affordability, energy efficiency, and proven performance on flat or low-slope roofs.
• PVC roofing is recommended for facilities exposed to grease, chemicals, or high fire risk—such as restaurants, manufacturing plants, and healthcare buildings.
• Metal roofing works best for warehouses, retail centers, or properties requiring long-term durability (40+ years) with minimal maintenance.

We assess your building, climate exposure, and budget to recommend the right system—not the most expensive one.

TPO roofs typically last 15–25 years with proper installation and regular maintenance. Membrane thickness, UV exposure, and seam quality all affect lifespan.

PVC roofs last 20–30 years or longer. PVC is more resistant to ponding water, chemicals, and extreme temperatures, making it one of the longest-lasting single-ply systems.

Key factors: Installation quality matters more than material alone. Poorly installed TPO can fail in 10 years, while expertly installed PVC can exceed 30 years.

We install both systems to manufacturer specifications and back our work with warranties that protect your investment.

Yes—metal roofing is one of the best long-term investments for commercial buildings.

Benefits of metal roofing for commercial properties:

• Longevity: Metal roofs last 40–70 years, often outlasting the building's lifespan
• Wind resistance: Standing seam metal can withstand hurricane-force winds
• Low maintenance: No membrane seams to fail or coatings to reapply
• Energy efficiency: Reflective finishes reduce cooling costs
• Fire resistance: Class A fire rating for insurance savings

Best for: Warehouses, retail centers, industrial facilities, and owners prioritizing lifecycle cost over upfront expense.

Signs your commercial roof needs replacement:

• Frequent leaks that return even after repairs
• Widespread membrane damage—cracks, punctures, or blistering across large areas
• Failed seams on TPO or PVC roofs (visible separation or water infiltration)
• Ponding water that doesn't drain within 48 hours after rain
• Interior damage—ceiling stains, mold, or insulation degradation
• Age: If your roof is 20+ years old and showing multiple issues, replacement is usually more cost-effective than continuous repairs

We provide honest roof assessments—if repairs will buy you 5+ years, we'll tell you. If replacement is the smarter financial decision, we'll explain why.

Flat and low-slope commercial roofs require routine maintenance to maximize lifespan:

• Twice-yearly inspections (spring and fall) to identify minor issues before they escalate
• Clear drains and gutters to prevent ponding water and membrane degradation
• Remove debris—leaves, branches, and dirt accelerate membrane wear
• Check seams and flashings—these are the most common failure points on TPO and PVC roofs
• Inspect after storms—high winds can lift membrane edges or puncture the surface with flying debris

Maintenance extends roof life by 5–10 years. We offer annual maintenance plans to keep your commercial roof in peak condition.

Commercial roof replacement costs vary based on size, material, and complexity:

• TPO roofing: $5–$8 per square foot installed
• PVC roofing: $7–$12 per square foot installed
• Metal roofing: $8–$15+ per square foot depending on panel type and finish

Factors affecting cost:

• Roof size and accessibility
• Membrane thickness or metal gauge
• Insulation upgrades or tear-off requirements
• Flashing complexity (HVAC units, skylights, parapets)
