6 Best Rubber Bungees For Securing Heavy Tarps

A loose tarp on a roof deck is more than a nuisance; it is a liability that invites moisture intrusion and creates dangerous wind uplift. Securing materials during a storm or throughout a multi-day roofing project demands reliable hardware that holds tension without failing under stress. Choosing the right rubber bungee determines whether the tarp stays pinned or ends up in the neighbor’s yard. This guide evaluates the top options for ensuring the job site remains buttoned up tight.

Keeper EPDM Rubber Straps: The All-Around Workhorse

Keeper EPDM straps are the industry standard for a reason. They offer a predictable stretch-to-tension ratio that works for almost any temporary cover application on a job site.

The EPDM (Ethylene Propylene Diene Monomer) construction provides excellent weather resistance. Unlike cheaper alternatives, these straps do not dry-rot after a few months in the sun.

Expect consistent performance when securing heavy-duty poly tarps over roof vents or material stacks. These straps maintain their grip in sub-zero temperatures and blistering summer heat, making them a safe year-round choice.

The Better Bungee: For Longevity & UV-Resistance

When a tarp must remain in place for weeks, standard rubber won’t suffice. The Better Bungee utilizes a high-grade rubber compound engineered to resist the structural degradation caused by constant UV exposure.

These straps are designed to handle significant tension without reaching a breaking point prematurely. Their design often features reinforced ends that prevent the common failure of hooks pulling through the rubber eyelet.

This is the preferred choice for long-term dry-ins where the tarp protects exposed plywood sheathing. If the budget allows, investing in this durability saves the time and potential damage costs associated with replacing snapped straps mid-project.

Erickson Tarp Straps: Best Value in a Bulk Pack

Construction sites chew through consumables quickly. Erickson tarp straps provide a reliable, no-nonsense solution for crews who need to secure multiple tarps simultaneously without breaking the bank.

These straps perform exactly as advertised, offering enough elasticity to pull a tarp taut over a stack of shingles or metal panels. While they may not have the premium longevity of specialized UV-resistant brands, they are perfectly suited for temporary site protection.

Purchasing in bulk allows for the inevitable loss or damage that occurs in high-traffic work zones. Keep a box of these in the gang box for quick site stabilization before a passing storm.

Vulcan Tarp Straps: Built for Heavy-Duty Hauling

Vulcan straps are designed for the rigors of the road, which translates well to heavy-duty site applications. Their superior tensile strength makes them the primary choice for securing oversized tarps that catch a lot of wind.

The rubber compound is dense and resistant to cold-cracking. This is critical if the job site is located in northern climates where standard rubber becomes brittle and shatters under moderate stress.

Use these when the stakes are high, such as protecting a roof with a steep pitch where a failing tarp could lead to significant water damage inside the building. Their weight and thickness provide a sense of security that thinner straps lack.

SmartStraps Adjustable Bungee: For a Perfect Fit

Sometimes a standard length just does not cut it. SmartStraps offer an adjustable mechanism that allows the tension to be dialed in precisely, preventing the tarp from flapping against the decking.

Adjustability is a massive advantage when securing tarps over irregular shapes, like chimney flashing or complex valleys. Getting that perfect, drum-tight fit prevents the “billowing” effect that leads to torn grommets and failed tarp edges.

While the adjustable hardware adds a point of mechanical complexity, the ability to tension the strap exactly where needed is invaluable. It is a smarter choice for detailed work where general-purpose straps are too loose or too short.

ProGrip T-Handle Straps: Easiest on Your Hands

Ergonomics matter when a crew is strapping down a massive tarp in freezing conditions or under a tight deadline. The T-handle design on ProGrip straps provides a secure anchor point for fingers, significantly reducing hand fatigue.

These handles offer better leverage when pulling the rubber tight. This is a noticeable upgrade when wearing heavy work gloves, where gripping standard round-end straps can feel clumsy and insecure.

Consider these for tasks that require frequent tensioning and untensioning, such as daily removal and replacement of tarps. Ease of use often leads to better compliance, meaning workers are more likely to tighten the straps correctly every time.

EPDM vs. Natural Rubber: Which Strap is Best?

Understanding material science separates a quick fix from a reliable system. Natural rubber, often found in cheaper straps, is highly elastic but degrades rapidly when exposed to sunlight and ozone.

EPDM, conversely, is a synthetic rubber built for outdoor durability. It is chemically stable and handles the expansion and contraction cycles of roofing materials without losing its elastic memory.

• Natural Rubber: Best for indoor storage, short-term usage, or low-cost applications.
• EPDM: The gold standard for external, long-term exposure and extreme temperature fluctuations.

Bungee Safety: Avoiding Snap-Back and Injury

A snapping bungee is a dangerous projectile. Always position yourself to the side of the tension line, never directly in the path of the hook’s trajectory should it slip or break.

Inspect every strap for micro-tears before every use. Even a small crack in the rubber can lead to a catastrophic failure under high-wind loads.

Never overstretch a strap beyond its rated limit in an attempt to reach a distant anchor point. If it does not fit easily, use a longer strap or an extension; over-extending a strap exponentially increases the risk of a high-velocity rebound.

Securing Tarps in High Winds: Pro Techniques

High wind creates uplift that can rip grommets right out of a tarp. To mitigate this, use more straps with less tension rather than a few straps stretched to their absolute breaking point.

Use “X” patterns or crisscross anchoring to distribute the load across the entire tarp surface. This prevents the wind from getting underneath the corners and creating a “sail” effect that lifts the cover off the roof.

Whenever possible, sandwich the tarp edges between 2×4 boards before fastening. This distributes the tension across the entire edge of the tarp, protecting individual grommets from tearing under heavy pressure.

How to Inspect and Store Your Tarp Straps

Rubber straps are not “set and forget” items. Perform a visual inspection every time they are pulled from storage, looking for “checkering” or fine spiderweb cracks that indicate chemical breakdown.

Store straps in a cool, dry place out of direct sunlight. Ultraviolet light is the primary enemy of rubber; leaving straps on a dashboard or in an open truck bed will shorten their lifespan by more than half.

Keep them organized by length using a simple carabiner or a dedicated hook. Proper storage ensures they stay tangle-free, which keeps the crew moving quickly when the next weather system hits.

Reliable tarping is the hallmark of a professional job site. By matching the right rubber strap to the specific conditions of the project, the risk of water damage and site failure is kept to a minimum.
