What Is ANJON EPDM Roofing Rubber (RoofShield)?
ANJON RoofShield is a 60-mil thick EPDM (ethylene propylene diene monomer) rubber membrane designed for flat and low-slope roofs. EPDM is a synthetic rubber known for its resistance to UV radiation, ozone, and extreme temperatures. This particular product comes in a 5-foot-wide by 100-foot-long roll, providing 500 square feet of coverage. It’s intended for use on residential flat roofs, commercial buildings, RVs, mobile homes, sheds, and other waterproofing projects. The manufacturer, ANJON MANUFACTURING, positions it as a commercial-grade option that meets ASTM D4637 standards for tensile strength and tear resistance.
Key Features & Specifications
Below is a summary of the product’s main characteristics as provided by the manufacturer.
| Feature | Details |
|---|---|
| Material | 60-mil EPDM rubber, black color |
| Dimensions | 5 ft wide x 100 ft long (roll); 500 sq ft total |
| Weight | Approximately 200 lbs per roll |
| Standards | ASTM D4637 compliant (high tensile/tear strength) |
| Low-Temp Flexibility | Remains flexible down to -49°F (-45°C) |
| UV Resistance | Superior resistance to cracking, fading, and degradation |
| Fire Rating | Low Slope Fire Retardant (LSFR) design |
| Intended Use | Flat/low-slope roofs, RVs, mobile homes, sheds |

The manufacturer emphasizes that the 60-mil thickness provides extra puncture resistance compared to standard 45-mil membranes. However, it’s worth noting that thicker material can be heavier and more challenging to handle during installation. ANJON also claims the membrane remains pliable even in extreme cold, which eases winter installations.
What’s Included in the Box
The product ships as a single roll of EPDM rubber, 5 ft wide and 100 ft long. According to the product details, the roll weighs about 200 pounds, so you’ll need assistance or mechanical help to move it. The box (or packaging) contains only the membrane itself—there are no accessories like adhesive, seam tape, primer, or fasteners. You must purchase those separately. The roll is shipped via LTL freight; a liftgate can be requested if needed. Make sure your delivery address is accurate and that someone can receive a heavy pallet or crate.
How to Use
Setup and Preparation
Before unrolling the membrane, the roof substrate must be clean, dry, and free of debris. For best results, apply a compatible EPDM primer and adhesive to the roof deck. The manufacturer recommends ordering a size slightly larger than your roof dimensions to allow for overlap and trimming. Because the roll is heavy, plan to unroll it directly onto the roof or use a rolling cart for safer handling. Always work with a partner.
Installation
Lay the membrane over the prepared surface, allowing a minimum 6-inch overlap at seams. Use EPDM seam tape or bonding adhesive to seal joints. For edges and protrusions (vents, pipes), apply suitable flashing and lap sealant. The material cuts easily with a sharp utility knife. For flat roofs, ensure proper drainage by sloping the membrane slightly toward drains. After installation, allow the adhesive to cure as per the product instructions before exposing the roof to heavy loads or foot traffic.
Maintenance
EPDM roofs require minimal upkeep. Periodically inspect for debris, standing water, or punctures. Clean with a mild soap and water solution; avoid harsh chemicals. Check seams and flashings annually for signs of separation. If small tears occur, they can be patched with EPDM repair tape and adhesive. The manufacturer states that with proper maintenance, the membrane can last over 20 years.
Troubleshooting
Blisters or bubbles: Usually caused by trapped moisture or incomplete adhesion. During installation, ensure the substrate is fully dry and the adhesive is applied evenly.
Seam failure: Use adequate pressure when applying seam tape. Roll the seam with a heavy roller to ensure full contact.
Punctures: Avoid dragging sharp objects across the membrane. If punctures occur, clean the area and apply a patch with EPDM adhesive tape.
Performance & User Experience
ANJON RoofShield is manufactured to meet ASTM D4637 standards, which means it has been tested for tensile strength, elongation, and tear resistance under controlled conditions. The 60-mil thickness is a notable upgrade over standard 45-mil sheets, offering extra puncture protection—useful for roofs with occasional foot traffic or debris impact. The low-temperature flexibility down to -49°F is a standout claim for those in colder climates, as many membranes become brittle in freezing weather.
Customer reviews (4.4 out of 5 stars from limited ratings) suggest general satisfaction, but with a small sample size. Some users appreciate the easy cutting and flexibility, while others note that the weight makes solo installation difficult. It’s important to set realistic expectations: EPDM is a proven material, but installation quality plays a huge role in long-term performance. The manufacturer’s claim of 20+ years is consistent with industry expectations for properly installed EPDM, but actual lifespan depends on local climate, roof condition, and maintenance.
Potential limitations include the need for specialized adhesives and sealants, which add to the overall project cost. Also, freight shipping can be cumbersome and may require scheduling a liftgate delivery if you lack a loading dock.

Comparison With Alternatives
When evaluating ANJON RoofShield, it helps to compare it with other common EPDM roofing options and alternative materials.
| Product | Thickness | Width Options | Standard Compliance | Typical Use |
|---|---|---|---|---|
| ANJON RoofShield 60-mil | 60 mil | 5 ft (other widths may be available) | ASTM D4637 | Flat roofs, RV, low-slope |
| Firestone RubberGard 60-mil | 60 mil | Various (6.5 ft, 10 ft, etc.) | ASTM D4637 | Commercial/residential flat roofs |
| Carlisle Sure-Seal 45-mil | 45 mil | Multiple widths | ASTM D4637 | Residential flat roofs, budget-conscious |
| TPO membrane (generic) | Typical 45-60 mil | Various | ASTM D6878 | Flat roofs, energy efficiency |
ANJON RoofShield competes directly with established brands like Firestone and Carlisle. The main differentiator is the wide width (5 ft) which may require more seams than a 10 ft wide sheet. However, the 60-mil thickness is a plus for durability. TPO membranes offer reflectivity and cool-roof benefits, but EPDM is often preferred for its ease of repair and flexibility in cold weather. Your choice should depend on local climate, roof slope, and personal preference for installation complexity.
Who Should Buy This Product?
Ideal for:
- Homeowners with flat or low-slope roofs seeking a durable, long-lasting membrane
- RV owners who want a heavy-duty replacement for a camper or motorhome roof
- DIY builders comfortable handling large, heavy rolls and working with EPDM adhesives
- Contractors needing a 60-mil commercial-grade membrane for smaller projects
- Anyone in cold climates who needs a flexible material for winter installation
Not ideal for:
- Beginners without experience in roofing or handling heavy materials
- Projects requiring a cool-roof (high solar reflectance) – EPDM is black and absorbs heat
- Ponds or fish-friendly water features – the product is not rated for aquatic life
- Jobs where 500 sq ft coverage is too much or too little; no smaller rolls appear available
- Those with limited access for freight delivery (narrow alleys, no liftgate)
Expert Tips
Based on general EPDM best practices, here are some tips to get the most out of your ANJON RoofShield installation:
- Always store the roll upright and indoors until use to prevent deformation.
- Use a compatible EPDM primer and adhesive system – do not mix brands without verifying compatibility.
- Apply seam tape only when the temperature is above 40°F and the surface is dry.
- Use a weighted roller (100 lbs or more) to press seams firmly.
- Allow a 12-24 hour cure time before exposing the roof to rain or foot traffic.
- For RVs, secure the membrane with appropriate fasteners and seal around vents with butyl tape and lap sealant.
- Consider ordering a roll 6-12 inches longer and wider than your roof to account for mistakes and overhang.
Common Mistakes
- Not ordering a large enough roll. Measure your roof carefully and add at least 6 inches per side for overhang. It’s better to have extra than to come up short.
- Forgetting to include the weight in your shipping plan. A 200-lb roll is not easy to move; arrange for a friend or dolly in advance.
- Skipping the primer or using wrong adhesive. EPDM bonding depends on proper surface prep. Using generic adhesives can cause delamination.
- Installing in wet or dusty conditions. Moisture and dirt compromise adhesion. Wait for clear, dry weather.
- Not allowing adhesive to cure before sealing seams. Follow manufacturer dwell times exactly.
- Overstretching the membrane. EPDM expands and contracts; stretching it tight can cause tears later. Let it lie naturally before adhering.
Where to Buy
The ANJON EPDM Roofing Rubber (RoofShield) is available through online retailers. Given its size and weight, ordering directly from Amazon or a specialty supplier can simplify logistics. Be sure to provide accurate contact information for freight delivery, and request a liftgate if needed.
Final Verdict
After reviewing the specifications, manufacturer claims, and typical EPDM performance, the ANJON EPDM Roofing Rubber appears to be a solid option for those needing a thick, commercial-grade membrane. Its 60-mil thickness, ASTM compliance, and extreme low-temperature flexibility are genuine advantages. The weight and lack of included accessories are downsides, but these are common to most bulk EPDM rolls. If you have the ability to transport and handle a heavy roll, and you’re comfortable with DIY roofing, this product is worth considering. For a first-time roofer or someone with a very small roof, a smaller roll or a different material might be more practical. Overall, this ANJON RoofShield review honest opinion suggests that the membrane itself is well-made, but success depends heavily on proper installation and compatible supplies.
