Shingle Sealer Rejuvenating Waterproofing Roof Sealer
Nationwide Coatings Shingle Sealer is designed to extend, preserve, and rejuvenate roof shingles. It penetrates shingles with polymers and acrylics, forming a breathable film that enhances durability. The sealer helps re-glue and secure loose granules while providing waterproofing and protection against the elements. It also offers a clear gloss finish that permeates porous surfaces to preserve, protect, and beautify the roof. A protective barrier helps prevent dirt and algae buildup, keeping the roof looking cleaner longer by repelling adherence of debris and facilitating sheeting water off the surface.
Rust-Oleum 710 Elastomeric Roof Coating
This elastomeric roof coating offers a 10-year warranty and a quick waterproof seal within six hours. It features Cool Roof Technology with high reflectivity to help save on energy costs by reducing heat transfer into the home. The product is designed for strong adhesion to shingles, with durable elasticity that tolerates temperature fluctuations and weathering, helping to protect against leaks and preserve shingle integrity over time.
Shingle Sealer Rejuvenating Waterproofing Roof Sealer (Gallon)
This gallon version of the Shingle Sealer mirrors the 5-gallon formulation, focusing on extending, preserving, and rejuvenating shingles. It uses a breathable, clear coating to maintain aesthetic appeal while enabling moisture vapor to escape. The sealant discourages the adherence of dirt and algae and provides a water-shedding surface that helps keep roofs visually cleaner longer.
PERMAKOTE Shingle Roof Coating
PERMAKOTE delivers a highly breathable, thick rubberlike ceramic shield coating. It uses ceramic microsphere technology to provide durability and elastomeric flexibility, while maintaining permeability to allow vapor to escape. The water-based high-build formula offers waterproofing, insulation, and some soundproofing benefits, enabling robust protection for shingle roofs while supporting energy efficiency. The Cocoa Brown variant is decorative, and the coating is also offered in bright white matte finishes for customization.
Rexoseal Clear Roof Shingle Coating (1 Gallon)
Rexoseal Clear Roof Shingle Coating is a highly flexible epoxy-urethane transparent coating designed to penetrate and protect roof shingles. It offers excellent adhesion and UV resistance to prevent degradation of the underlying substrate or coating. The clear formulation is suitable for preserving the natural color of shingles while delivering durable protection against moisture and weather exposure.
PERMAKOTE Shingle Roof Coating (5 Gallon)
The 5-gallon version of PERMAKOTE provides a bright white matte finish or color-matching options through fan deck or custom colors. It uses a breathable elastomeric formula with ceramic technology for long-lasting protection and weather resistance. The high-build, water-based composition supports durability and helps insulate and potentially dampen sound, while enabling vapor permeability essential for shingle roofs.
Rust-Oleum 750 Elastomeric Roof Coating
The 750 elastomeric coating from Rust-Oleum emphasizes a long warranty, quick waterproofing, and Cool Roof Technology with high reflectivity. It is designed to minimize heat gain and provide durable protection against weathering. The coating’s elastomeric properties accommodate movement in roofing materials, helping prevent cracks and leaks around shingles, vents, and flashing.
Rexoseal Clear Roof Shingle Coating (5 Gallon)
This five-gallon Rexoseal Clear provides a highly flexible epoxy-urethane clear coating with strong UV resistance and excellent adhesion. It is designed to penetrate and protect roof shingles, delivering long-lasting clarity and protection while preserving the underlying material’s appearance. The product is suitable for larger roof areas or projects requiring a clear, durable coating that withstands sun exposure.
Buying Guide: Key Purchase Considerations
- Finish and appearance: Decide between clear, white, or color-matched coatings. Clear coatings preserve shingle color while adding protection, while white or colored finishes can reflect solar heat more effectively.
- Breathability and permeability: Shingle roofs require vapor permeability to prevent moisture buildup beneath the coating. Look for elastomeric formulations with breathable properties.
- Flexibility and elasticity: Coatings should accommodate roof movement and temperature changes without cracking. Elastomeric compounds are typically preferred for longevity.
- Waterproofing and seal efficiency: A primary purpose is preventing leaks. Consider products with quick-set waterproofing and robust film formation.
- UV resistance: UV-stable coatings resist sun degradation, preserving color and adhesion over time.
- Energy efficiency: Reflective or Cool Roof technologies can reduce cooling costs. Check reflectivity percentages when available.
- Application and maintenance: Evaluate ease of application, required tools, cure times, and recoat intervals.
- Coverage and warranty: Larger capacities (5 gallons) may reduce per-square-foot cost. Review manufacturer warranties for expected lifespan.
- Environmental and safety considerations: Check VOC content and any application restrictions in your area.
- Color options and aesthetics: For visible roofs, color choice can impact curb appeal and neighborhood guidelines.
Choosing the right roof coating involves balancing durability, reflectivity, and appearance with the roof’s exposure and climate. The products listed above provide a range of finishes and performance characteristics to meet different needs, from quick-seal performance to long-term, reflective protection.
