AMES Maximum-Stretch Roof Coating — White
Overview: A white, elastomeric acrylic roof coating with 650% elongation to resist cracking and peeling. Its bright white finish reflects sunlight effectively to lower surface temperatures. Best for low-slope roofs, metal, tar, and rolled surfaces.
- Best for: Roofs needing high flexibility and resistance to cracking, including RV roofs and metal surfaces.
- Why selected: Combines extreme elongation with strong adhesion to common roofing substrates.
- Caution: Substrate preparation is important to maximize adhesion on older surfaces.
Rust-Oleum 710 Elastomeric Roof Coating, 5 Gallon
Overview: A 5-gallon white elastomeric coating with high reflectivity and weather resistance. It provides long-term protection for various roof types and helps reduce heat absorption.
- Best for: Larger roofs or projects needing a single-coat coverage with durable protection.
- Why selected: Strong reflectivity and weather resistance support energy savings and roof longevity.
- Caution: Extended curing times may occur in cooler, damp conditions; ensure proper ventilation during application.
Gardner-Gibson Sta-Kool 15-Year Turbo-Dri
Overview: A white, elastomeric roof coating with Cool-Core technology designed to repel heat and keep interiors cooler. Marketed as rain-safe in 30 minutes and recoatable in three hours.
- Best for: Fast-track roof projects needing quick protection from rain and heat.
- Why selected: The combination of heat-reflective pigments and rapid curing supports faster completion times.
- Caution: Performance may vary with heavy roofing textures; follow recoat times carefully to maintain seal integrity.
PERMAKOTE Shingle Roof Coating — 1 Gal
Overview: A 15-year elastomeric ceramic-coated roof coating that forms a breathable, 16 MILS membrane over shingles. Ceramic microspheres reinforce the dried film to resist wind lift and salt spray.
- Best for: Shingle roofs needing durable waterproofing with heat-dissipating properties.
- Why selected: Ceramic heat-dissipating technology helps reduce cooling costs and enhances longevity.
- Caution: Supports long-term protection, but surface prep remains essential for optimal adhesion on older shingles.
Rust-Oleum 710 Elastomeric Roof Coating — Gallon (2 Pack)
Overview: A two-pack white elastomeric coating with 10-year warranty and quick waterproofing. Cool Roof Technology claims high reflectivity to lower cooling costs.
- Best for: Projects needing redundancy or a spare coating kit for future touch-ups.
- Why selected: The two-pack format supports strong sealant performance and system longevity.
- Caution: Ensure compatibility with existing coatings and proper mixing before use.
Buying Guide: White Roof Coatings For Shingle Roofs
What to consider when choosing a roof coating
Key factors include reflectivity, application method, cure time, and substrate compatibility. A higher reflectivity rating reduces heat gain, while elastomeric properties improve flexibility and crack resistance on aging shingles.
Reflectivity and energy savings
Look for coatings with white or light-reflective pigments and a documented reflectivity percentage. Higher reflectivity generally correlates with greater cooling cost savings over time.
Durability and weather resistance
Elastomeric formulations with rubberized binders offer stretch to resist thermal movement and minor roof flexing. Consider products with UV resistance and wind-driven rain protection for long-term performance.
Application, curing, and maintenance
Single-day or rapid-dry products enable faster completion. Check recoat windows and readiness for foot traffic or maintenance access after curing. Confirm surface preparation requirements for best adhesion.
Compatibility and substrate coverage
Most coatings adhere to metal, tar, and shingle surfaces, but substrate-specific instructions vary. For flat or low-slope roofs, ensure ponding is addressed; some formulas offer water drainage considerations.
Warranty and guarantees
Many coatings offer extended warranties or “rain-safe” claims, but durable performance depends on surface prep and proper application. Verify warranty terms and regions of coverage if available.
FAQ
- What is the best white roof coating for energy savings?
– Coatings with high reflectivity and elastomeric properties, such as ceramic- or pigment-enhanced formulations, tend to offer the strongest energy-saving potential. - Can I apply these coatings over existing coatings?
– Many products require clean, sound surfaces. Some can be applied over existing coatings; others need scraping or priming. Follow the manufacturer’s prep instructions. - How long does a roof coating take to cure?
– Most coatings cure within hours to a day, but full cure may take longer depending on temperature, humidity, and substrate. - Is a two-pack coating better than a single-pack coating?
– Two-pack options can offer faster initial set and added durability, but check mixing requirements and surface compatibility. - Are white roof coatings safe for RV roofs?
– Yes, several products are marketed for RV and mobile home applications due to flexible adhesion and reflective finish.
