Rust-Oleum Elastomeric Roof Coating 4.75 Gal 710 White - High

In this review of the Rust-Oleum 710 Elastomeric Roof Coating the bottom line is straightforward: it is aimed at homeowners and maintenance pros who want a reflective, durable coating to waterproof and protect existing roofs without a full replacement. The reviewer found the product's single biggest advantage to be its high initial reflectivity and weather resistance, which help lower surface temperatures and extend roof life. Application felt familiar to anyone who has used latex roof coatings, and the stated quick rain resistance and ASTM D 6083 compliance make it a practical choice rather than a speculative one.

Key Features

• High initial reflectivity: With 84% initial reflectivity reported, the coating helps reduce roof heat gain and improves energy efficiency right after application.
• Weathered reflectivity: Maintains a strong 74% reflectivity after weathering, so benefits persist beyond the first season.
• Rain resistant fast: Becomes rain resistant in about 6 hours, allowing faster project completion in changing weather.
• Broad substrate compatibility: Formulated to waterproof metal, weathered single-ply membranes and smooth asphalt built-up and modified bitumen surfaces for flexible use.
• ASTM D 6083 formulation: Meets or exceeds the ASTM standard for elastomeric roof coatings, which supports reliability and long term performance.

Who It's For

The coating is best for property owners, RV and motorhome owners, and maintenance contractors who need a cost-effective roof refresh rather than replacement. It suits those working on metal roofs, aged single-ply membranes, and smooth built-up or modified bitumen roofs who value reflectivity and waterproofing in one product.

Those who should look elsewhere include people with heavily damaged roofing that needs structural repair, or anyone requiring a textured or granule-surfaced finish; the 710 is formulated for smooth substrates and repair/maintenance rather than full roof reconstruction.

Pros & Cons

Pros

• Easy to apply and goes on like thick latex, which customers noted improves application control.
• High initial and retained reflectivity offer meaningful energy and heat-reduction benefits.
• Quick rain resistance in about 6 hours and full cure faster in warm climates helps shorten project time.
• Meets ASTM D 6083, indicating industry-standard weathering and durability characteristics.

Cons

• Not intended for roofs requiring structural repair or for heavily textured/granular surfaces, so preparation may be needed.
• Curing times vary with temperature, so cooler climates may see slower full cure than described by some customers.

Specifications

Our Verdict

Rust-Oleum 710 is a sensible option for homeowners and maintenance teams seeking an elastomeric coating that combines high reflectivity, waterproofing and ease of application. It delivers solid coverage and weather resistance for smooth substrates and represents good value for routine roof maintenance and energy-minded projects.

Frequently Asked Questions

Can this be used on metal roofs?
Yes, it is formulated to waterproof and weatherproof metal roof surfaces as well as smooth single-ply and built-up substrates.

How soon will it resist rain after application?
The manufacturer states the coating becomes rain resistant in about 6 hours, though full cure depends on temperature and conditions.

Does it meet industry standards?
Yes, the formula is designed to meet or exceed ASTM D 6083 for elastomeric roof coatings.
