Polyurethane Roof Coatings
High-performance elastomeric coating offering superior impact resistance and durability for demanding commercial applications
Key Benefits
- ✓ Best-in-class tensile strength for high-traffic areas
- ✓ Superior adhesion to SPF, EPDM, TPO, modified bitumen, and BUR
- ✓ Excellent resistance to chemicals, acids, and hydrocarbons
- ✓ 10-20 year warranty potential with proper maintenance
- ✓ Aromatic base coat + aliphatic UV-stable topcoat system
Two Types of Polyurethane
Aromatic (Base Coat)
- • Less UV stable
- • More economical
- • Excellent adhesion
- • Ideal as primer or base
- • High impact resistance
Aliphatic (Top Coat)
- • UV stable
- • Color retention
- • Higher cost
- • Excellent weathering
- • Clean aesthetic finish
Best Applications
Polyurethane coatings excel in:
- • High foot traffic areas
- • Roofs with mechanical equipment
- • SPF (Spray Polyurethane Foam) protection
- • Industrial facilities with chemical exposure
- • Areas prone to hail or impact damage
Technical Specifications
| Property | Typical Value |
|---|---|
| Solids Content | 70-100% |
| Tensile Strength | 1000-2000 psi |
| Elongation | 200-400% |
| Shore A Hardness | 70-85 |
| Application Thickness | 20-30 dry mils |
Installation Considerations
Important Notes:
- • Requires moisture-free surface
- • Strong odor during application (proper ventilation needed)
- • Professional application recommended
- • May require primer on certain substrates
- • Full cure: 7-14 days depending on conditions
Hybrid System Approach
Many contractors use polyurethane in combination with other coatings for optimal performance:
- • Aromatic polyurethane base coat for adhesion and impact resistance
- • Acrylic or aliphatic top coat for UV protection and reflectivity
- • This combination maximizes durability while managing costs
Cost Analysis
Polyurethane coatings range from $3-6 per square foot installed. While more expensive than acrylic, the superior durability and impact resistance make it cost-effective for high-traffic or demanding environments.
ROI Considerations:
Extended service life (15-25 years) and reduced maintenance needs often justify the higher initial investment.
