Polyglass Polyfresko costs $2.50 to $4.00 per square foot installed.
Polyglass Polyfresko is a premium self-adhering modified bitumen roofing membrane known for its reflective white surface and energy efficiency. The cost per square foot typically ranges from $2.50 to $4.00 when fully installed, depending on factors like roof complexity, location, and contractor pricing. This price includes materials and labor but may vary based on roof size and preparation needs.
Cost breakdown by component
- Material cost: $1.20 to $2.00 per sq ft
- Labor cost: $1.30 to $2.00 per sq ft
- Additional accessories (flashing, fasteners): $0.10 to $0.30 per sq ft
Comparison with other roofing materials
| Material | Cost per sq ft | Lifespan |
|---|---|---|
| Polyfresko | $2.50 - $4.00 | 20-25 years |
| TPO | $3.00 - $5.00 | 15-20 years |
| EPDM | $1.50 - $3.00 | 20-30 years |
Factors affecting Polyfresko pricing
- Roof size: Larger roofs may have lower per-square-foot costs due to economies of scale
- Roof complexity: Steep slopes, multiple penetrations, or unusual shapes increase labor costs
- Geographic location: Labor rates and material shipping costs vary by region
- Removal of existing roofing: Additional $0.50 to $1.50 per sq ft if old material must be removed
Installation considerations
- Surface preparation: Clean, dry substrate is essential for proper adhesion
- Temperature requirements: Installation typically requires temperatures above 40°F (4°C)
- Seaming: Heat-welded seams provide watertight connections between membrane sheets
- Flashing details: Special attention needed around edges, penetrations, and transitions
Energy efficiency benefits
Polyfresko's reflective white surface can reduce cooling costs by 10-30% compared to traditional dark roofing materials. The material's high reflectivity (typically 80% or higher) and emissivity ratings contribute to lower roof surface temperatures and improved building energy performance.
