6 Best Heavy Duty Staples For Temporary Holding

Temporary holding is the silent workhorse of any roofing or siding installation, often determining the final quality of the finished assembly. Whether positioning synthetic underlayment before the final deck fasteners go in or securing drip edge to a rake board, the right staple keeps materials flush and prevents the wind from turning a job site into a disaster area. Choosing the wrong fastener leads to frustrating pull-throughs, damaged membranes, or unnecessary holes in the substrate. This guide breaks down the essential heavy-duty staples that hold tight when the pressure is on.

Arrow T50 1/2-Inch Staples: The All-Around Classic

The Arrow T50 is the gold standard for a reason. These staples are universally compatible with a massive range of manual tackers, making them the most accessible option for site-wide repairs or quick underlayment adjustments.

When the objective is simple membrane holding, the 1/2-inch leg length provides enough bite to penetrate through felt or synthetic underlayment without blowing through the bottom of a thin decking board. They are reliable for basic tasks, though they lack the specialized anti-corrosion coatings required for high-exposure environments.

Treat these as the primary choice for interior work or short-term exterior holding where the material will be covered within a day or two. If the job involves leaving an underlayment exposed to the elements for more than 48 hours, look for a more weather-resistant alternative.

DeWalt DWHTTA708 Staples: Pro-Grade Durability

These staples are engineered for professional-grade pneumatic and heavy-duty manual tackers. The steel gauge is slightly thicker than standard DIY alternatives, which means less deformation when driving into dense materials like OSB or kiln-dried pine.

The extra rigidity is a major asset when installing thicker vapor barriers or heavy-duty tarps on a job site. Because they hold their shape under high-impact fire, they are less likely to jam the magazine of a power tacker during a long day of rapid-fire installation.

For contractors who demand consistency, these staples minimize downtime. They bite hard and stay put, making them a go-to for securing temporary protection over a roof deck during a multi-day project.

Stanley TRA700 Series: Best for General Repairs

Stanley’s TRA700 series offers a balanced tensile strength that makes them ideal for a wide variety of general repair tasks. They are surprisingly resistant to breakage, even when the tacker is being used at an aggressive angle.

They perform well in the heat of the summer, where some thinner staples tend to lose their structural integrity under the stress of heat-expanded building materials. These are perfect for keeping in a truck box for those miscellaneous repairs that crop up during a punch list walkthrough.

Use these for non-critical, temporary holding where the speed of the application is the priority. They are not intended for structural load-bearing applications, so keep them reserved for materials that will be properly fastened with screws or nails later.

Bostitch BTA700 Staples: Top Pick for Power Tools

Bostitch has built a reputation on tool performance, and their staples are designed to handle the high velocity of pneumatic fastening systems. If the job involves rapid, repetitive work—like securing thousands of feet of house wrap—this is the staple that won’t fail in the gun.

The consistency of the leg length and crown width is exceptional, which prevents the “staple train” from breaking inside the tool. This reliability is vital when working on high-slope roofs where a jammed tool is not just an annoyance, but a significant safety hazard.

Choose these when time is money. They are precision-engineered to ensure that every trigger pull results in a clean, flush fastener that holds the material securely until the permanent siding or roofing finish is applied.

Surebonder #4 Staples: Great Value for Bulk Jobs

Surebonder staples provide a cost-effective solution for large-scale projects where thousands of staples will be used. They are designed to fit most standard heavy-duty guns and provide a surprisingly sturdy hold for the price point.

While they may not possess the high-end anti-corrosive properties of specialized stainless fasteners, they are more than adequate for indoor remodeling or temporary outdoor protection. For a renovation job where the budget is tight and the scope is large, these offer the best value for keeping materials in place.

Use these for high-volume tasks where staples are being discarded quickly. They allow for a lower cost-per-fastener without sacrificing the basic integrity required for short-term holding.

Grip-Rite GRT5012S: Contractor’s Choice Staple

Grip-Rite staples are a common sight on commercial job sites, and for good reason. They are manufactured to meet the rigorous demands of professional contractors who need a fastener that survives being dropped, stepped on, or stored in humid job-site conditions.

The point of these staples is consistently sharp, which reduces the force needed to drive them through tough materials like asphalt-impregnated felt. This ease of penetration makes them ideal for manual hammering or heavy-duty manual stapling when a power tool isn’t convenient.

If the project requires a reliable, no-nonsense fastener that won’t fail under job-site abuse, look toward the Grip-Rite line. They bridge the gap between hobbyist-grade fasteners and expensive specialty hardware.

Staple Material: Galvanized vs. Stainless Steel

Material selection is the most common oversight in temporary roofing and siding applications. Standard galvanized staples provide a temporary barrier against rust, but they will eventually degrade if exposed to moisture, salt air, or harsh chemicals.

• Galvanized: Best for short-term projects that will be covered quickly.
• Stainless Steel: Mandatory for coastal areas or high-moisture environments.

Using the wrong material can lead to “bleeding,” where rust stains run down the face of your siding or underlayment. Always match the fastener material to the duration of exposure and the specific climate conditions of the job site.

Choosing the Right Staple Leg Length and Crown

The leg length is dictated by the thickness of the material you are fastening and the density of the substrate underneath. A 1/2-inch staple is usually the sweet spot for most roofing underlayments, as it provides enough purchase without penetrating too deep into the rafters.

The crown, or the top bar of the staple, determines how much surface area is holding the material. A wider crown is generally better for thin materials like plastic sheeting or house wrap, as it prevents the staple from tearing through the material under high wind loads.

Always assess the substrate density before buying. Driving a long, heavy-duty staple into dense hardwood can result in a “kickback,” where the staple bends and fails to hold entirely.

Manual Tacker vs. Hammer Tacker: Which to Use

Manual tackers provide precision for delicate materials like flashing or precise corners where control is paramount. Hammer tackers are the tool of choice for roofing underlayment, as they allow for rapid installation across large surfaces with a single swing.

• Manual Tacker: Use for finish work, upholstery, or slow-paced, high-accuracy installations.
• Hammer Tacker: Use for flat surfaces, underlayment, and jobs where speed dictates the timeline.

A master roofer knows when to switch between these tools to ensure the highest quality hold. Trying to use a hammer tacker on intricate metal trim will usually result in damaged materials and frustration.

Staples vs. Cap Fasteners: Code & Wind Uplift

Staples are excellent for temporary holding, but they are rarely acceptable for the final, permanent attachment of underlayment in high-wind zones. Most modern building codes require cap fasteners—which use a plastic or metal disc to increase the holding surface—to resist wind uplift.

Temporary holding with staples should never be confused with the final mechanical fastening required by local building departments. Always verify if the manufacturer of the underlayment specifies the type of fastener needed to maintain the warranty.

If the region is prone to high winds or extreme weather, assume that staples are only for positioning the material. Follow up immediately with the code-compliant cap fasteners to ensure the assembly remains intact during the first storm cycle.

The difference between a seamless job and a callback is often the attention to detail paid during the preparation phase. Using these staples as part of a strategic, temporary holding plan will keep the site clean and the materials secure, allowing for a professional finish every time.
