Asphalt Roof Coatings
Aluminum-pigmented elastomeric coating solution for built-up roofs and modified bitumen systems. SBS rubber-modified asphalt roof coating products extend the life of aging BUR systems at a fraction of tear-off cost.
Key Benefits
- ✓ 0.68 initial solar reflectance with aluminum pigment
- ✓ SBS rubber modified for enhanced flexibility
- ✓ Specifically formulated for BUR and modified bitumen
- ✓ Reduces UV degradation and heat damage
- ✓ 300% elongation and tensile strength per ASTM D-412
Types of Asphalt Coatings
Solvent-Based
- • Quick drying
- • Better penetration
- • Works in cooler temperatures
- • Higher VOC content
- • Stronger odor
Water-Based Emulsion
- • Environmentally friendly
- • Lower VOCs
- • Easier cleanup
- • Requires warmer application temps
- • Longer dry time
Best Applications
Asphalt coatings are ideal for:
- • Built-up roofing (BUR) systems
- • Modified bitumen restoration
- • Older asphalt shingle roofs
- • Gravel roof restoration
- • Budget-conscious waterproofing projects
Technical Specifications
| Property | Typical Value |
|---|---|
| Solids Content | 40-60% |
| Tensile Strength | 50-150 psi |
| Elongation | 100-300% |
| Application Temperature | 50°F minimum |
| Coverage Rate | 1-2 gallons per 100 sq ft |
Aluminum-Pigmented Options
Aluminum asphalt coatings (also called "silver coatings") provide additional benefits:
- • Enhanced UV protection
- • Improved reflectivity (50-70%)
- • Reduced surface temperature
- • Extended coating life
- • Better aesthetics than black asphalt
Installation Considerations
Important Notes:
- • Surface must be clean and dry
- • Not compatible with single-ply membranes
- • Black coatings absorb heat (consider aluminum)
- • Recoating needed every 3-5 years
- • May require multiple coats for proper thickness
Limitations
Consider these limitations:
- • Lower reflectivity than modern elastomerics
- • Shorter lifespan (5-10 years)
- • Limited color options
- • Can become brittle with age
- • Environmental concerns with solvent-based options
Cost Analysis
Asphalt coatings are the most economical option at $0.50-1.50 per square foot installed. While they require more frequent reapplication, they remain popular for budget-conscious projects and temporary solutions.
Best Value For:
Existing asphalt-based roofs needing short to medium-term protection at minimal cost.
Upgrade Path
Many building owners start with asphalt coatings then upgrade to modern elastomeric systems. When you're ready to step up, commercial roofing products from US Made Supply cover every major coating chemistry. Consider transitioning to:
- • Acrylic for better reflectivity and energy savings
- • Silicone for ponding water resistance
- • Polyurethane for high-traffic areas
