Rust-Oleum Elastomeric Roof Coating – 710 White
Rust-Oleum’s elastomeric coating in white provides a durable layer designed for shingle roofs. The coating helps reflect sunlight, reducing heat transfer into living spaces and extending roof life. It offers high initial reflectivity (84%) and weathered reflectivity (74%), supporting performance after sun, rain, and temperature changes. It becomes rain resistant in about six hours, allowing quicker return to service. The white finish aids cooling, while the elastomeric formula accommodates roof movement to minimize cracking and peeling over time. Its flexible film resists cracking with roof movement in heat and cold.
Designed for ready-to-use application on clean, dry surfaces, this coating forms a seamless protective layer that helps shield asphalt shingles from moisture and UV stress. It is suitable for most typical roof decks and is compatible with existing coatings when properly prepared. For best results, apply when temperatures are above 50°F (10°C) and ensure adequate drying time before weather exposure. Regular maintenance coats extend protection, and the white finish can help lower cooling costs by reducing heat buildup on the roof. Additionally, it adheres well to clean surfaces and resists chalking over time.
BLACK JACK Roof And Foundation Coating
BLACK JACK 6190 is a 4.75-gallon asphalt emulsion roof coating designed to weatherproof and seal roof surfaces. It is odorless and solvent-free, making it suitable for enclosed spaces during application. The product is water-based and versatile enough to seal foundations and metal surfaces as well as roofing. This coating forms a weatherproof film that resists water intrusion and temperature changes, helping protect shingles, underlayment and roof decks from leaks and wear over time. The water-based formula reduces odor and cleanup time, important for residential installations.
Application requires a clean, dry surface and typical roof prep steps such as removing loose debris and repairing obvious damage. The coating is designed for roofing and foundations and supports sealing metal joints and flashing to extend service life. For color options and compatibility with existing coatings, consult the label before applying. Plan for dry weather and a proper cure window to maximize performance and minimize disruption to the roof’s surface.
Liquid Rubber Waterproof Sealant – 1 Gallon
Liquid Rubber Waterproof Sealant delivers a seamless, rubberized membrane ideal for flat, metal, and low-slope roofs, as well as foundations and gutters. The product uses an industrial-strength bitumen formula that forms a durable barrier against water infiltration, reducing the risk of leaks around seams and fasteners. It offers exceptional elasticity—over 950% elongation—allowing the coating to move with temperature changes and building movement without cracking. The sealant also resists UV damage and remains flexible in varied climates, extending roof life for shingles and other roof types.
Coverage varies by surface: for flat/low-slope roofs and standing water surfaces, one gallon covers about 15 square feet with 3-4 heavy coats to reach a 60-80 mil membrane; for vertical surfaces like foundations, one gallon covers roughly 30 square feet with 2-3 heavy coats for a 30 mil film. This flexibility supports both patching and long-term restorations. Application can be done with brush, roller, or spray on clean, dry surfaces. Plan multiple coats and allow curing time between passes. It also helps patch small gaps and joints before re-coating.
Gardner-Gibson 6125-9-34 FB Roof Coating
Gardner-Gibson 6125-9-34 FB Roof Coating is a straightforward, durable coating designed for easy application on common roofing substrates. Manufactured in the United States, it emphasizes reliability for low-slope roofs and as a rejuvenating layer over existing coatings. The product forms a protective seal that resists weathering and helps extend the life of shingles, underlayment and roof decking. It is marketed as user-friendly, enabling homeowners to perform maintenance or refresh projects without specialized equipment. Compatibility with several roof types makes it a versatile option for seasonal upkeep. This makes it a practical choice for homeowners on a budget seeking steady performance.
Key strengths include ease of use, high durability, and U.S.-made quality. The coating is designed to be applied by brush or roller on typical shingles and other roof surfaces, enabling a straightforward refresh. While it is robust, users should assess existing coatings and surface cleanliness before applying and avoid application in wet or freezing conditions. Always read the label for surface prep steps and cure times.
AMES MSS1 Maximum Stretch Roof Coating – 1 Gallon
AMES RESEARCH LABORATORIES MSS1 Maximum Stretch Roof Coating is a white elastomeric acrylic coating designed for low-slope roofs. With up to 650% elongation, it resists cracking and peeling as the roof moves with temperature changes. The bright white finish reflects sunlight, offering around 88% reflectivity to help lower cooling costs. The coating adheres to metal roofing, tar, rolled roofs, and other common substrates, making it suitable for RVs, flat systems, and general roof maintenance. It is easy to apply by brush, roll or spray, and provides versatility for different roofing needs.
Application guidance includes brushing, rolling, or spraying on clean, dry surfaces. The product is designed for easy, multi-coat coverage, allowing for a durable seal that tolerates roof movement. As with all elastomeric coatings, proper surface prep—removing debris, repairing damage, and avoiding wet or freezing conditions—improves adhesion and longevity. While it prioritizes white reflectivity, color options may also exist to match aesthetics and energy goals, though performance varies with pigment choice. The white finish helps reflect solar heat, supporting cooler attics and living spaces.
Buying Guide
Key purchase considerations when selecting a roof coating for shingles include climate and weather patterns, roof condition, desired reflectivity, coating elasticity, ease of application, and maintenance expectations. The following guide compares common attributes across the top products and explains how to choose the best fit for your home.
Key Factors To Consider
- Roof type and surface compatibility: Elastomeric coatings work well on metal, asphalt, and other common shingles; asphalt emulsions are versatile for sealing and weatherproofing on a range of roof types.
- Reflectivity and heat reduction: White or light-colored coatings reduce heat absorption, which can lower cooling costs in hot climates. Note initial vs. weathered reflectivity when evaluating long-term performance.
- Elasticity and durability: Higher elongation indicates better resistance to cracking as the roof expands and contracts with temperature shifts. This is especially important for long-term protection of shingles and decking.
- Application and curing: Consider temperature ranges for application, drying times, and whether brushes, rollers, or spray equipment are suitable for your project. Some products require multiple coats for the desired thickness.
- VOC content and odor: Odorless or low-VOC formulas are preferable for indoor or tight spaces, improving working conditions during application.
- Coverage and cost: Check per-gallon coverage rates and total project coverage, factoring in the number of coats required for a durable membrane. Higher-elasticity products may cost more upfront but offer longer life.
- Color options and aesthetics: White coatings reflect heat and help with cooling, while some products are available in colors for aesthetic or specific energy goals; verify color stability over time.
- Surface preparation: Most coatings require cleaning, debris removal, and repair of damaged areas before application. Improper prep reduces adhesion and longevity.
Product Comparisons At A Glance
- Elastomeric white coatings (like Rust-Oleum and AMES MSS1) excel in heat reflectivity and flexibility but may be more sensitive to UV exposure over many years; regular re-coating helps maintain performance.
- Aphalt emulsions (such as BLACK JACK 6190) provide robust waterproofing with strong foundational sealing capabilities and can be odorless or low-odor, depending on formulation.
- Liquid Rubber products offer superior elasticity and waterproof membranes, with high elongation and multi-surface suitability, though application may require careful surface prep and multiple coats.
- Made-in-the-USA options (Gardner-Gibson) emphasize ease of use and durability for home maintenance projects, often balancing cost with long-term protection.
