What’s Included in the Box

The ANJON EPDM Roofing Rubber arrives as a single heavy-duty roll (5 ft x 100 ft) shipped via LTL freight. No additional accessories, adhesives, or fasteners are included. You will need to purchase separate bonding adhesive, seam tape, and termination bars depending on your installation method. The product is packaged in a protective wrapper to prevent damage during transit.

How to Use

Setup

Before installation, ensure the roof surface is clean, dry, and free of debris. Unroll the membrane on a flat area to allow it to relax and acclimate to the ambient temperature. The manufacturer recommends ordering slightly larger than your roof dimensions (e.g., add 6–12 inches on each side) for full coverage and anchoring.

Installation

EPDM membranes like Roofshield can be fully adhered, ballasted, or mechanically fastened. For a permanent bond, use a compatible EPDM adhesive applied to both the substrate and the membrane. Rolls are heavy (200 lbs); having at least two people during unrolling is advisable. Cut the material with a sharp utility knife; seal seams with lap sealant or splice tape per manufacturer instructions.

Maintenance

Once installed, EPDM requires minimal upkeep. Periodically inspect seams, flashings, and edges for any lifting or damage. Remove debris such as leaves or branches to prevent water pooling. The material is resistant to algae and mildew, but gentle cleaning with a mild detergent and water can be done if needed.

Troubleshooting

If the membrane appears to shrink after installation, verify that it was properly secured and that the adhesive was applied at the correct temperature (above 40°F recommended). For small tears or punctures, use an EPDM patch kit. For larger issues, the entire sheet may need replacement.

Performance & User Experience

Based on the manufacturer’s technical data and general industry knowledge of 60-mil EPDM, ANJON Roofshield should provide robust protection against UV radiation, ozone, and thermal cycling. The thickness likely reduces the risk of punctures compared to 45-mil alternatives, making it suitable for high-traffic commercial areas or RV roofs that experience vibration and debris. The flexibility at -49°F is a practical advantage for cold-climate installations.

User reviews (4.4 out of 5 stars from 3 ratings – limited data) indicate satisfaction with durability, but the small sample size means expectations should be tempered. No information on long-term field testing is publicly available beyond the manufacturer’s own quality claims.

Pros and Cons

Pros

• Thick 60-mil membrane offers enhanced puncture and tear resistance.
• Meets ASTM D4637 standards for commercial-grade performance.
• Excellent low-temperature flexibility (tested to -49°F).
• Low Slope Fire Retardant (LSFR) design adds a safety layer.
• Suitable for multiple applications: flat roofs, RVs, sheds, waterproofing.
• Manufacturer claims 20+ year lifespan with proper installation.

Cons

• Very heavy roll (200 lbs) – may require assistance or equipment for unloading and installation.
• No accessories (adhesive, tape) included – must be purchased separately.
• Limited user reviews available, making independent performance verification difficult.
• Not rated for fish/wildlife or potable water applications.
• LTL freight shipping can be cumbersome; accurate contact info and liftgate request may be needed.
• Potential for shrinkage if not installed with proper adhesive and temperature conditions.

Comparison With Alternatives

For context, here’s how ANJON Roofshield stacks up against other common EPDM roofing options:

• Firestone RubberCover 60-mil: A well-known competitor with extensive warranty programs. Firestone offers a 20-year warranty when installed by certified contractors. ANJON does not include a published warranty beyond manufacturer claims.
• Carlisle Sure-Seal 45-mil: Thinner and lighter, making DIY installation easier, but with slightly lower puncture resistance. Suitable for low-traffic residential applications. ANJON’s 60-mil offers more robustness.
• Dura-Bond 60-mil EPDM: Similar thickness and ASTM certification. Dura-Bond is often sold with a 20-year limited warranty. ANJON may be more affordable but has fewer reviews and less brand recognition.

Ultimately, ANJON competes well on thickness and standards compliance, but buyer confidence may be lower due to its newer market presence.

Who Should Buy This Product?

Ideal Users

• DIY homeowners covering a flat roof or low-slope porch with basic carpentry skills.
• RV owners seeking a thick, durable membrane for harsh travel and UV conditions.
• Small contractors or property managers working on outbuildings, sheds, or multi-unit low-slope roofs.
• Anyone needing a reliable EPDM membrane that meets ASTM D4637 without paying for a premium brand warranty.

Not Ideal Users

• First-time DIYers with no experience handling heavy rolls or applying adhesive – consider a lighter 45-mil option.
• Those seeking an all-in-one kit with adhesives, tape, and edge trim – this product is membrane only.
• Projects requiring potable water containment or pond liners – ANJON is not rated for fish/wildlife safety.
• Users who want a long-term factory warranty – ANJON’s warranty terms are not clearly published.

Expert Tips

1. Order extra material: Add at least 6 inches of overhang on all sides to account for cutting errors and secure anchoring.
2. Use a compatible primer and adhesive: Not all adhesives work the same with 60-mil EPDM; check with the adhesive manufacturer for compatibility with ASTM D4637 membranes.
3. Install when temperature is above 50°F: Cold reduces adhesive tack and flexibility; avoid installation below 40°F unless using low-temp adhesive.
4. Protect the roll before use: Store the roll on a clean, dry surface away from direct sunlight to prevent premature aging.
5. Seam splice tape is critical: For overlapping sections, use wide (6-inch) splice tape and a roller to ensure a watertight bond.

Common Mistakes

1. Not allowing the membrane to relax/flatten before installation – causes wrinkles and poor adhesion.
2. Skipping the primer on porous substrates (wood, concrete) – leads to adhesive failure.
3. Applying adhesive in direct sun on a hot surface – adhesive can skin over too quickly.
4. Forgetting to account for expansion – leave small gaps at edges or use expansion joints per roof design.
5. Ignoring the weight of the roll – attempt to lift it alone can cause injury or damage the roll.
6. Not verifying shipping details – LTL carriers will not unload without a liftgate request; provide a phone number in advance.

Where to Buy

ANJON EPDM Roofing Rubber is available through online retailers including Amazon. Due to its size and weight, it ships via LTL freight. Ensure your delivery address can accommodate a freight truck and consider requesting a liftgate if you don’t have a loading dock.

Final Verdict

ANJON EPDM Roofing Rubber (60-mil) is a solid, commercially compliant membrane that delivers the thickness and durability expected from an ASTM D4637-rated product. It is well-suited for flat roofs, RVs, and low-slope applications where a tough, long-lasting layer is needed. The main drawbacks are the heavy weight, lack of included accessories, and limited user review history. If you are comfortable handling a large, heavy roll and sourcing your own adhesives, this offers good value for the price. However, if you prefer an all-in-one kit with a clear warranty, better-known brands like Firestone or Carlisle may provide more peace of mind.
