Introduction

When your roof needs replacement—whether it’s a flat residential roof, a commercial building, or an RV—choosing the right material is critical for long-term protection. EPDM (ethylene propylene diene terpolymer) rubber has long been a trusted choice for low-slope and flat roofs due to its durability, flexibility, and weather resistance. The ANJON EPDM Roofing Rubber (5 ft x 100 ft, 60-mil) is a heavy-duty membrane designed for such applications, promising a 20+ year lifespan with minimal maintenance. In this ANJON EPDM roofing rubber review, we examine the product’s features, real-world usability, and potential drawbacks to help you decide if it’s the right choice for your project. Whether you’re a DIY homeowner or a contractor looking for a reliable commercial-grade membrane, this review covers everything from installation to long-term performance.

What Is ANJON EPDM Roofing Rubber?

ANJON EPDM Roofing Rubber, also known as RoofShield, is a synthetic rubber membrane designed for waterproofing low-slope and flat roofs. It comes in a single roll measuring 5 feet wide by 100 feet long, with a thickness of 60 mils (0.06 inches). The product is intended for residential, commercial, and RV applications, offering a durable, weather-resistant surface that can withstand extreme temperatures, UV exposure, and heavy rainfall. Unlike some other roofing membranes that require hot asphalt or torching, ANJON EPDM is installed using adhesive and seam tape, making it accessible for both professional contractors and experienced DIYers. The manufacturer, ANJON MANUFACTURING, positions this as a commercial-grade solution that meets ASTM D4637 standards for tensile strength and tear resistance, ensuring it can handle the demands of high-traffic areas and harsh climates.

The LSFR (Low Slope Fire Retardant) rating adds a safety layer, making it suitable for commercial buildings where fire codes apply. The roll size covers 500 square feet, but careful planning is needed since the 5-foot width may require multiple seams for wider roofs.

What’s Included in the Box

When you order the ANJON EPDM Roofing Rubber roll, you receive the membrane itself—no adhesives, seam tape, or termination bars are included. The product ships via LTL freight due to its size and weight (approximately 200 lbs). It arrives folded or rolled, depending on the manufacturer’s packaging. You will need to purchase the following separately:

• EPDM primer and bonding adhesive (water-based or solvent-based)
• Seam tape and lap sealant
• Roof edge termination bars and fasteners
• A utility knife for cutting
• A roller or stiff broom for pressing the membrane into the adhesive

Because the membrane is supplied without accessories, it’s essential to read the manufacturer’s installation guidelines before starting. Many DIYers find that buying a ANJON EPDM roofing rubber review or installation kit from the same brand can simplify the process.

How to Use

Setup

Before unrolling the ANJON EPDM membrane, ensure the roof surface is clean, dry, and free of debris. Existing roofing materials (such as gravel or old shingles) should be removed or smoothed out. Prime the substrate with an EPDM-compatible primer and allow it to dry as recommended by the adhesive manufacturer. The membrane is heavy—two people are recommended to handle the roll. Lay it out loosely over the roof area, allowing a few inches of overhang on all sides. Do not attempt to stretch the rubber; instead, let it settle naturally in warm temperatures for easier handling.

Operation

Application requires careful planning of seams. Since the roll is only 5 feet wide, roofs wider than that will need parallel runs of membrane with overlapping seams (usually 3–6 inches). Use seam tape and lap sealant to bond the overlaps. For edges and penetrations (vents, pipes, skylights), apply termination bars and sealant. Work slowly, starting from the lowest point of the roof to allow water runoff. Adhesive is applied to the roof surface, and the membrane is rolled into it. Use a roller to remove air bubbles and ensure full contact. Allow the adhesive to cure for the time specified by the product.

Maintenance

Once installed, ANJON EPDM requires very little upkeep. The manufacturer states that the rubber is resistant to aging, ozone, and UV damage. Over time, you may need to inspect edges and seams for lifting or damage after severe weather. Remove debris such as leaves or branches that could cause ponding water. Avoid using petroleum-based solvents near the membrane, as they can degrade EPDM. Hosing down the roof occasionally with mild soap and water can help maintain its appearance and performance.

Troubleshooting

If you notice blisters or bubbles after installation, they may be caused by moisture trapped beneath the membrane. Small blisters can often be sliced, drained, and patched with a rubber patch and sealant. Wrinkles that appear during installation can be minimized by allowing the membrane to relax in warm sunlight before adhering. For leaks around penetrations, check the condition of the sealant and reapply as needed. If the membrane lifts at edges, the primer or adhesive may not have cured properly—clean and reapply with fresh adhesive.

Performance & User Experience

ANJON MANUFACTURING markets this membrane as “commercial grade” with a 20+ year lifespan when installed correctly. While we haven’t personally tested the product over decades, the specifications align with industry expectations for 60-mil EPDM. The ASTM D4637 compliance ensures a baseline of tensile strength and tear resistance. Users should expect the membrane to perform well under moderate foot traffic (such as routine maintenance visits) but understand that all EPDM can be punctured by sharp objects. The black color is standard for EPDM and absorbs heat, which may slightly increase roof surface temperature in summer but also helps with snow melt in winter.

From installation perspective, the 5-foot width may be a limitation for large roofs because it creates more seams than wider membranes. However, for typical home flat roofs or RV roofs (which are often less than 10 feet wide), the width is manageable. The flexibility at low temperatures is a notable advantage—many rubber membranes become brittle below 0°F, but this one claims to stay pliable at -49°F. If you live in a very cold climate, this could be a deciding factor. The LSFR fire rating provides peace of mind for structures near heat sources or in wildfire-prone areas.

Potential drawbacks include the need to source additional installation materials separately, which may add complexity for first-time DIYers. Some users on Amazon (4.4 out of 5 stars, though only based on 3 ratings) mention the product is heavy and difficult to maneuver without help. Shipping via LTL freight requires accurate contact information and may involve extra fees for liftgate service if you don’t have a loading dock. Overall, the product appears to deliver on its claims, but the small sample size of reviews means we should wait for more user feedback before drawing strong conclusions.

Pros and Cons

Pros

• Heavy-duty thickness: 60-mil provides extra puncture and tear resistance compared to standard 45-mil membranes.
• Excellent weather resistance: Manufacturer states the rubber resists UV, ozone, and extreme temperatures (down to -49°F).
• Low maintenance: EPDM is inherently durable and requires minimal upkeep over its lifespan.
• Fire-resistant design: LSFR rating adds safety for commercial buildings.
• Suitable for various applications: Works on flat roofs, RVs, sheds, mobile homes, and low-slope commercial roofs.

Cons

• No accessories included: You must purchase adhesive, seam tape, and termination bars separately, which increases total cost and installation complexity.
• Narrow width (5 ft): Creates more seams on wider roofs; seams are potential failure points if not installed correctly.
• Heavy and cumbersome: 200 lbs roll requires two people to handle, and shipping via freight may be inconvenient.
• Limited verified reviews: Only three customer ratings on Amazon at the time of writing, making it hard to gauge long-term satisfaction.

Comparison With Alternatives

Product	Thickness	Width	Temperature Range	Fire Rating	Application
ANJON EPDM Roofing Rubber	60 mil	5 ft	-49°F to ?	LSFR	Flat/low-slope roofs, RVs
Firestone RubberGard 60-mil	60 mil	10 ft	-40°F to 250°F	Class A (with cover board)	Commercial flat roofs
Carlisle Sure-Seal 60-mil	60 mil	10 ft	-40°F to 250°F	LSFR	Flat roofs, RVs
DAP EPDM Roof Coating	Liquid (applied)	N/A	Varies	N/A	Patch repairs, small areas

Compared to industry giants like Firestone and Carlisle, ANJON offers a similar thickness at a potentially lower price point (though we are not discussing pricing). The main difference is the 5-foot width, which means more seams for large roofs. Firestone and Carlisle provide wider rolls (10 ft or more) that reduce seam count, and they come with established warranties. However, ANJON’s claim of flexibility down to -49°F is slightly better than the -40°F typical of competitors. For RV owners, width may be less of an issue since most RV roofs are 8 ft wide or less. The DAP liquid coating is a different category entirely—best for small repairs rather than full replacements. If you prioritize minimizing seams and want a well-known brand, Firestone or Carlisle may be worth considering. But if you need a heavy-duty membrane for a smaller roof or RV and are comfortable handling a narrower roll, ANJON is a competent option.

Who Should Buy This Product?

Ideal for:

• Homeowners with flat or low-slope roofs (up to about 20 ft in width) who plan to DIY install and have experience with adhesives.
• RV owners looking for a durable, flexible replacement roof membrane that can handle travel vibration and UV exposure.
• Contractors who need a reliable 60-mil membrane for small commercial projects and are comfortable managing multiple seams.
• Anyone who values extreme cold-weather flexibility for use in northern climates.

Not ideal for:

• Large commercial roofs (over 50 ft wide) where fewer seams are critical to waterproofing integrity.
• First-time DIYers without prior experience installing EPDM or similar flat roofing systems, as the lack of included accessories can lead to mistakes.
• Pond liners or fish-safe waterproofing applications (manufacturer states not rated for wildlife use).
• Projects requiring immediate availability of accessories—you must source them separately.

Expert Tips

• Plan your seams carefully: Position the membrane so that seams run parallel to the roof’s slope, and overlap by at least 3 inches. Use a seam roller to ensure full adhesion.
• Prime everything: Even if the adhesive claims to stick without primer, applying a primer to the substrate and the underside of the membrane improves bond strength and reduces blistering.
• Work in moderate temperatures: Install when the ambient temperature is between 50°F and 85°F. Too cold, and the adhesive may not cure properly; too hot, and the rubber may expand uncontrollably.
• Use a liftgate service: Since the roll weighs 200 lbs, request a liftgate when ordering to avoid unloading difficulties. Ensure delivery address has enough space to handle a large roll.
• Allow the membrane to relax: Before applying adhesive, unroll the membrane and let it lay flat for 30–60 minutes. This reduces tension and prevents curling after installation.

Common Mistakes

1. Not ordering enough material: The roll covers 500 sq ft, but you need extra for overlaps and edges. Measure your roof area and add 10% to account for waste.
2. Skipping the primer: Even on clean concrete or plywood, priming enhances adhesion. Skipping this step can lead to delamination over time.
3. Ignoring the manufacturer’s instructions: Each EPDM system has specific requirements for adhesive drying time, seam bonding, and cure times. Follow them closely.
4. Applying in damp conditions: The substrate must be completely dry. Moisture trapped under the membrane can cause blisters and mold growth.
5. Not protecting penetrations properly: Vents, pipes, and skylights require careful flashing with EPDM compatible accessories. Use pre-formed boots or cut and seal carefully.
6. Overstretching the rubber: EPDM is flexible but should not be pulled tight. Allow a slight sag so it can contract without tearing in cold weather.
7. Using incompatible sealants: Some silicones and polyurethanes can react with EPDM. Use only products labeled for EPDM rubber.
