Buying Guide
- Reflectivity and energy savings: Choose coatings with high reflectivity ratings (often indicated as a percentage) to maximize sun heat rejection and reduce cooling costs.
- Fiber reinforcement: Fibered formulas generally offer greater elongation and crack resistance, which is important for metal and aged roofs that move or flex.
- Weather resistance: Look for water resistance and sealing capability to prevent rust and leaks in diverse climates, especially with metal roofs.
- Warranty and life expectancy: Durable products often come with multi-year warranties; consider the expected service life in your climate and roof type.
- Application and packaging: For larger roofs, 5-gallon pails are efficient; smaller cans suit spot repairs or maintenance coatings.
- Compatibility: Verify roof material compatibility (metal, tar, and rolled roofs) and whether the coating adheres to your existing roof system.
- Color and heat management: Silver and metallic finishes balance reflectivity with aesthetic preferences; white coatings may offer higher reflectivity in some climates.
- Environmental and safety considerations: Check VOC content and surface preparation requirements to ensure safe, compliant application.
