What’s Included in the Box

The ANJON RoofShield EPDM roofing is sold as a single roll. It is important for buyers to understand exactly what they are receiving. The product is shipped via LTL freight, meaning it comes on a pallet and will require a truck for delivery. Due to the 200-pound weight, ensure the delivery location is accessible for a large truck.

What you can expect in the shipment:

• One (1) roll of ANJON RoofShield EPDM Rubber: 5 feet wide by 100 feet long. This is the primary material.

What is NOT included: EPDM is an adhered system. To install it, you will need to purchase separate components, including an EPDM compatible bonding adhesive (water-based or solvent-based), seam primer, splicing tape, and a caulk or sealant for perimeter edges. The manufacturer does not include a starter kit or accessories with this roll, which is standard for raw membrane sold in bulk.

How to Use

Installing an EPDM membrane is a significant project that requires careful planning and physical effort. While ANJON states that RoofShield is suitable for DIY installation, it is essential to follow standard best practices for adhered EPDM systems. The following information is based on general industry installation guidelines for EPDM.

Preparation & Setup

Proper surface preparation is the most critical step. The substrate must be clean, dry, structurally sound, and free of sharp debris, oil, or grease. Common substrates include plywood, OSB, and rigid insulation board. The environment should also be considered; installation is typically recommended in temperatures above 40°F (4°C) for proper adhesive curing, although the material itself can handle cold. It is wise to unroll the membrane and lay it flat on the roof for a period (often 15-30 minutes) to allow it to relax and relax out any memory from being rolled.

Operation & Installation

The standard method for installing an adhered EPDM system involves rolling out the membrane over the substrate and positioning it to allow for a minimum overhang (usually 2-3 feet) on all sides. The membrane is then folded back halfway, and adhesive is applied to both the substrate and the membrane according to the adhesive manufacturer’s instructions. The membrane is then carefully folded back into place and rolled out with a heavy roller to remove air bubbles and ensure a secure bond. This process is repeated for the other half. Seams are handled separately using a specific primer and splicing tape.

Maintenance

Once installed, EPDM is a low-maintenance material. Routine maintenance primarily involves keeping the roof clean. Debris like leaves and branches should be removed periodically to prevent staining and blockage of drainage systems. Roof jacks, satellite dishes, or other equipment should be flashed properly if installed after the membrane. A periodic visual inspection, especially after severe weather, is recommended.

Troubleshooting Common Issues

• Wrinkles: Small wrinkles are often a cosmetic issue that can relax over time as the membrane heats up and cools down. Larger wrinkles may be caused by improper adhesive application or failing to allow the membrane to relax before bonding.
• Poor Adhesion: If the membrane does not adhere well, it is typically due to a dirty or damp substrate, incorrect adhesive, or applying adhesive at temperatures outside the recommended range.
• Seam Leaks: The vast majority of EPDM roof leaks occur at seams or flashings. Ensuring proper overlap, using the correct primer, and applying firm pressure with a hand roller is essential for watertight seams.

Performance & User Experience

Since this is a relatively new product listing with a limited number of public reviews, it is important to frame performance expectations around the inherent properties of 60-mil EPDM rubber and the specific claims made by ANJON Manufacturing.

The manufacturer claims that RoofShield resists cracking, shrinking, and UV degradation. This is consistent with the well-documented performance characteristics of quality EPDM. The 60-mil thickness provides a higher degree of puncture resistance compared to standard 45-mil membranes. This is a tangible benefit for roofs that experience foot traffic, falling branches, or heavy hail.

The temperature rating down to -49°F is notable and suggests the compound is formulated to maintain flexibility in harsh northern climates. The LSFR designation adds a safety component that meets many building code requirements for low-slope structures.

Potential Limitations:

• Weight: At 200 pounds for the 5×100 roll, handling this material can be challenging for a single person. A strong lifting team is required to get the roll onto the roof.
• Limited Track Record: With only a few customer reviews available, the long-term performance track record for this specific product is not yet established by public feedback, though the material itself is based on proven technology.
• Shipping Logistics: LTL freight requires a physical address with a loading dock or a forklift. Residential delivery can sometimes be challenging and may require arranging for a liftgate, which the manufacturer notes is available upon request.

Expert Tips for a Successful Installation

Based on standard best practices for EPDM installation, here are some practical tips for getting the best results with the ANJON RoofShield.

1. Order Extra Material: Always order 1-2 feet longer and wider than your roof dimensions. This allows for edge overhangs and minor errors during cutting. The manufacturer recommends this as well.
2. Invest in Quality Adhesives: The bonding adhesive is the most critical component. Use a high-quality EPDM bonding adhesive and the manufacturer recommended primer for your substrate.
3. Use a Walk-Up Roller: Renting or buying a heavy, weighted floor roller (often available at tool rental shops) is invaluable for pushing out air bubbles and ensuring full contact between the membrane and the adhesive.
4. Install Flashing Properly: Pipe penetrations, roof edges, and corners are the most common leak points. Pre-form corners and use the correct unsupported seam tape for these details.
5. Work on a Warm Day: While the material is flexible down to -49°F, the adhesive cures best when temperatures are consistently above 50°F during installation and for 24 hours after.

Common Mistakes to Avoid

1. Neglecting Surface Preparation: Failing to clean, dry, and smooth the substrate is the number one cause of EPDM failure. Debris, moisture, and dust will prevent a solid bond.
2. Using the Wrong Adhesive: EPDM requires specific rubber bonding adhesives. Using a general construction adhesive or contact cement will likely lead to poor adhesion and delamination.
3. Improper Seaming: Not using the correct seam primer before applying splicing tape. The primer activates the rubber for a chemical bond. Also, failing to apply firm pressure along the seam edges with a hand roller.
4. Forgetting a Drip Edge: A metal drip edge installed along the perimeter protects the edge of the membrane from wind uplift and gives a clean finish.
5. Working in Wet Conditions: EPDM adhesive will not bond to a wet surface. Ensure the roof is dry and that rain is not expected for at least 24 hours after installation.
6. Underestimating the Weight: Failing to plan for moving the 200-pound roll onto the roof. Ensure you have enough people or a lift when the freight arrives.
