What Is ANJON EPDM Roofing Rubber?

ANJON EPDM Roofing Rubber is a 60-mil (0.060 inch) thick synthetic rubber membrane designed for flat and low-slope roofs. It is manufactured by ANJON MANUFACTURING and sold under the “RoofShield” brand. The product is intended for residential, commercial, and RV applications where reliable waterproofing is needed. EPDM (ethylene propylene diene monomer) is a well-known roofing material valued for its resistance to UV radiation, ozone, extreme temperatures, and weathering. This particular version is marketed as heavy-duty commercial-grade, with claims of meeting ASTM D4637 standards for tensile strength and tear resistance. The roll measures 5 feet wide by 100 feet long, covering up to 500 square feet. It comes in black and is packaged as a single roll weighing approximately 200 pounds. The product is aimed at both DIY homeowners and professional contractors who need a durable, flexible membrane that can be bonded to various substrates using EPDM-compatible adhesives.

• Heavy-Duty Construction: The 60-mil thickness is common for commercial-grade membranes, offering extra puncture resistance and longevity compared to thinner 45-mil sheets. The manufacturer claims high tensile and tear strength per ASTM D4637.
• Low Temperature Flexibility: The material is said to stay flexible down to -49°F, which is important for climates with extreme cold where other membranes might crack.
• LSFR Fire Retardant: Designed to slow flame spread on low-slope roofs, adding a layer of safety.
• RV & Mobile Home Use: The flexibility and UV resistance make it suitable for vehicles that undergo constant thermal expansion and contraction.
• Shipping Considerations: Ships via LTL freight – you must provide accurate contact information for delivery. Liftgate service is available on request.

These features position the ANJON EPDM membrane as a competitor to established brands like Firestone or Carlisle. However, as with any product, real-world performance depends on proper installation and surface preparation.

What’s Included in the Box

The product ships as a single roll of EPDM rubber (5 ft x 100 ft). There are no additional accessories, adhesives, primer, seam tape, or installation tools included. The roll is delivered via LTL freight truck, typically on a pallet. The 200-pound weight means you may need help moving it into position. For full installation, you will need to purchase separately: EPDM bonding adhesive, lap sealant (if seaming multiple rolls), splice tape, primer, and possibly a roller or squeegee. The manufacturer does not provide any instructional materials inside the box – installation guidance is available from the product listing or through online resources. Keep this in mind when budgeting for your project.

How to Use

Setup

Before installing, unroll the membrane and allow it to relax for 30–60 minutes, especially if stored in a cold environment. The surface (roof deck) must be clean, dry, and free of debris, grease, or old adhesive. Plywood, OSB, concrete, or metal decks are common substrates. Apply a manufacturer-recommended EPDM primer if needed, then roll out the adhesive according to the adhesive manufacturer’s instructions. Position the rubber so that it overlaps edges by at least 3 inches. Some installers prefer to dry-fit the sheet first.

Operation

Once the adhesive is applied and the membrane is laid down, use a heavy roller (e.g., 75–100 lb) to ensure full contact and remove air bubbles. Seams can be bonded with lap sealant or splice tape. For roof penetrations (pipes, vents), use EPDM pipe boots and sealant. Allow the adhesive to cure per the manufacturer’s timeline – often 24–48 hours before exposing to rain. The membrane requires no further operation once installed; it simply provides a waterproof barrier.

Maintenance

EPDM membranes generally require minimal upkeep. Inspect the roof annually for debris, ponding water, or damage at seams. Clean with a gentle soap solution and soft brush if needed. Avoid harsh chemicals or power washing that could degrade the rubber. Trim any tree branches that could drop debris or abrade the surface. If repairs are needed, EPDM patch kits are available from the same manufacturer or others.

Troubleshooting

If you notice wrinkling or bubbles after installation, they often stem from trapped air or moisture. Puncture or tear damage can be patched with an EPDM patch and adhesive. Poor adhesion is usually due to incomplete cleaning or incorrect primer. If the membrane seems to shrink or pull away at edges, recheck that the adhesive was properly applied and that the substrate is suitable. For RV roofs, ensure the rubber is not stressed by sharp corners – use radius corners or trim carefully.

Performance & User Experience

The manufacturer claims the ANJON EPDM membrane meets ASTM D4637 standards, which define requirements for EPDM sheets used in roofing. This includes tensile strength, elongation, and tear resistance. With a 60-mil thickness, it is thicker than standard 45-mil consumer-grade membranes, so it should offer improved puncture resistance. The flexibility claim of -49°F suggests it can perform in very cold climates without cracking. The LSFR (Low Slope Fire Retardant) designation means it has been tested for flame spread, which is important for building code compliance on low-slope roofs.

User reviews (as of the time of writing) are limited – only 3 customer ratings on Amazon, but they average 4.4 out of 5 stars. This indicates early adopters are generally satisfied, though the sample size is too small to draw strong conclusions. Common positive points from such reviews typically mention ease of cutting and handling (despite the weight), good adhesion, and a clean install. Some users might note that the roll is heavy and requires help to maneuver.

In terms of limitations, the product does not come with adhesive, seam tape, or detailed instructions. This is normal for bulk membrane rolls, but first-time DIYers may underestimate the need for additional supplies. Additionally, the 200-pound weight can be a hurdle for a single person on a roof. The product is not rated for pond or wildlife applications, so it should not be used in fish-safe environments. Overall, if installed correctly on a suitable substrate, this membrane should provide the decades of protection the manufacturer promises.

Pros and Cons

Pros

• 60-mil thickness offers robust puncture resistance compared to thinner membranes.
• Low-temperature flexibility down to -49°F – suitable for cold climates.
• LSFR fire retardant adds safety and may help with code compliance.
• Large roll size (5 ft x 100 ft) covers 500 sq ft, reducing seams.
• Compatible with standard EPDM adhesives and accessories from various brands.
• Manufacturer provides a detailed FAQ and claims 20+ year lifespan with proper installation.

Cons

• Heavy roll (200 lbs) may require two people and careful planning for rooftop installation.
• No adhesive or installation accessories included – additional purchase necessary.
• Limited customer reviews available – long-term reliability data is sparse.
• Not suitable for fish or wildlife ponds due to potential leaching concerns.
• Shipped via LTL freight with potential for delivery delays or damage if not properly secured.
• Color only available in black, which absorbs heat – may not be ideal in hot climates without ballast or coating.

Comparison With Alternatives

Below is a balanced comparison of the ANJON EPDM membrane with two common alternatives: a standard 45-mil EPDM roll from a well-known brand (e.g., Firestone) and a TPO membrane (another single-ply roofing option).

Feature	ANJON EPDM 60-mil	Standard 45-mil EPDM	TPO Membrane (60-mil)
Thickness	60 mil	45 mil	60 mil (typical)
Material	EPDM rubber	EPDM rubber	Thermoplastic polyolefin
Puncture Resistance	Higher (thicker)	Moderate	Good
Flexibility at Low Temp	Down to -49°F	Typically down to -40°F	Good but can stiffen below -20°F
UV Resistance	Excellent (EPDM)	Excellent	Good (white TPO reflects UV)
Seaming	Adhesive/tape only	Adhesive/tape	Heat-welded seams
Fire Rating	LSFR	Typically Class A with ballast	Class A available
Common Applications	Flat roofs, RVs, sheds	Residential flat roofs	Commercial low-slope roofs
Installation Complexity	Moderate (adhesive)	Moderate	Higher (heat welding equipment)

Key Differences: The ANJON 60-mil offers thicker material than standard consumer 45-mil EPDM, providing extra durability without the need for heat welding (unlike TPO). However, TPO’s heat-welded seams can be more reliable than adhesive seams if done correctly. TPO is often lighter in color and may reduce cooling costs in hot climates, but EPDM’s flexibility in extreme cold is superior. For most DIY flat roof or RV projects, a 60-mil EPDM like this one strikes a good balance of toughness and ease of installation.

Who Should Buy This Product?

Ideal Users

• DIY homeowners with a flat roof (garage, shed, addition) who want a durable, single-ply membrane they can install with adhesive.
• RV and camper owners planning a full roof replacement – the 60-mil thickness can handle road vibrations and UV exposure while remaining flexible for curves.
• Contractors who need a large roll for commercial or multi-unit applications and already have a stock of EPDM adhesives.
• Property owners in cold climates where roof membranes must withstand freeze-thaw cycles and extreme low temperatures.

Not Ideal For

• First-time DIYers who have never worked with roofing adhesives – the weight and preparation requirements may be overwhelming.
• Small projects under 100 sq ft – the 5 ft x 100 ft roll is oversized and may be wasteful unless you can store and use the remainder.
• Pond or water garden applications – the manufacturer explicitly warns against fish and wildlife use.
• Steep-slope roofs – EPDM membranes are best for flat or low-slope (up to 2:12 pitch) and may not be suitable for steeper pitches without special fastening.

Expert Tips

1. Surface preparation is everything: Clean and prime the deck thoroughly. Use a vacuum and mild detergent, then an EPDM primer specifically rated for your substrate.
2. Always unroll and relax: Let the membrane lie flat in a warm area (or sunlight) for at least an hour before cutting; this reduces memory and makes it easier to lay flat.
3. Use a roller – not just a broom: A heavy carpet roller or dedicated roofing roller (75-100 lbs) ensures full contact with the adhesive, eliminating air pockets that can lead to blistering.
4. Overlap seams generously: Minimum 3 inches for side laps and 6 inches for end laps, and apply lap sealant on both edges for a watertight bond.
5. Consider a ballast or coating: On a flat roof with poor drainage, adding ballast (stone or pavers) or a reflective coating can reduce ponding damage and improve solar reflectance.

Common Mistakes

1. Skipping the primer: Many DIYers think adhesive alone is enough. Without primer, adhesion can fail, especially on porous surfaces like plywood.
2. Installing on a wet or damp deck: Moisture trapped under the membrane will turn to steam and create bubbles. Always check for moisture with a plastic sheet test.
3. Not ordering enough material: The 5 ft x 100 ft roll covers 500 sq ft. If your roof has penetrations or complex shapes, order 10-15% extra to account for waste and overlaps.
4. Ignoring the weight: Trying to lift a 200-lb roll onto a roof without a plan can cause injury or damage the membrane. Use a ladder and a helper or a roof lift.
5. Using an unapproved cleaner: Petroleum-based solvents can degrade EPDM. Only use mild soap or isopropyl alcohol for cleaning.
6. Forgetting about seam tape orientation: If using splice tape, apply it to the bottom side of the overlapping piece, not the top. Follow the tape manufacturer’s instructions exactly.
