TPO vs EPDM vs PVC: Utah Commercial Roofing Comparison

Here's the summary before we dive into details:

TPO: Best overall value. White/reflective, heat-welded seams, handles UV well. Most popular choice for general commercial use. Cost: $$

EPDM: Lowest cost option. Black rubber (white available), adhered seams, proven track record. Good for budget-conscious projects. Cost: $

PVC: Best chemical resistance. White/reflective, heat-welded seams, superior durability. Ideal for restaurants and industrial. Cost: $$$

All three can work in Utah's climate. The choice depends on your budget, building use, and priorities.

TPO: TPO is relatively new (widespread since the 2000s), so we don't have 50-year track records yet. Current experience suggests 20-30 year lifespan with proper installation. Quality has improved significantly in recent years.

EPDM: EPDM has been around since the 1960s. We have proven 30+ year installations. It's durable and handles weather well. The weak point is seams—adhered or taped seams can fail before the membrane itself.

PVC: PVC also has a long track record—40+ year installations exist. It's the most durable of the three, especially in harsh conditions. Heat-welded seams are strong and reliable.

All three handle Utah's temperature extremes. PVC and TPO handle UV better than black EPDM; white EPDM addresses this but adds cost.

Installed costs per square foot (approximate ranges):

EPDM: $5-$8 per sq ft installed. The most affordable option, especially for basic installations.

TPO: $6-$10 per sq ft installed. Moderate cost with good value considering performance.

PVC: $8-$12 per sq ft installed. Premium pricing for premium performance.

For a 10,000 sq ft roof: EPDM might cost $50,000-$80,000, TPO $60,000-$100,000, PVC $80,000-$120,000.

But consider total cost of ownership. TPO and PVC energy savings can offset higher initial costs. EPDM's potentially shorter seam life might mean earlier repairs.

Choose TPO when:

• You want the best balance of cost and performance
• Energy efficiency (cooling costs) matters
• General commercial use (offices, retail, warehouses)
• Budget is moderate and value is the priority

Choose EPDM when:

• Budget is the primary concern
• Building is in a shaded area (less UV concern)
• Short-term ownership plans
• Simple roof with minimal penetrations

Choose PVC when:

• Chemical exposure is a concern (restaurants, industrial)
• Maximum durability is required
• Long-term ownership with low maintenance priority
• Budget allows premium investment
