The 1-1/8″ size supports larger heads, helping to distribute pressure and guard against fastener pull-through on roofing felt, rigid boards, and radiant barriers.

They offer improved resistance to downward load and a tight seal against moisture, suitable for roofing felt, insulation, and house wrap installations. Compatibility with common nail and screw sizes makes these washers a flexible option for various project needs, particularly where a matte finish is preferred for concealment on dark substrates.
(500 Pack) Round Plastic Cap Nail 1 Inch
This 500-pack from One Stop Outdoor extends the benefits of the 1-inch plastic cap nails by offering more quantity for bigger roof projects. The nails are electro-galvanized, affording corrosion resistance and longer service life. The round cap design helps minimize water entry under the cap while simplifying installation, making them a dependable option for roofing felt, tar paper, insulation film, and house wrap.
Buying Guide: Key Purchase Considerations
- Material and corrosion resistance: Look for electro-galvanized nails and durable plastic caps to prevent rust and ensure a long service life in outdoor weather conditions.
- Cap design and water sealing: Round, flexible caps with integrated heads typically seal better against moisture than flat or exposed-head designs.
- Size and compatibility: Match washer or cap size to your fastener size (#11–#12 nails or #6–#8 screws) and the surface area of the cap to evenly distribute load.
- Application fit: Choose washers compatible with roofing felt, tar paper, house wrap, foam board, and insulation films. Consider extra versatility for holding cords or lighting when needed.
- Quantity and project scale: For larger roofs, higher-count packs reduce shopping trips; smaller jobs can be well served by 100–250 packs.
- Color and visibility: White or black caps can affect visibility on different roofing substrates; choose a shade that minimizes contrast against roof materials if desired.
- Made in USA or global production: Some products highlight USA-made manufacturing, which can be a factor for some buyers seeking local supply chains.
- Avoidance of treated lumber: Some products specify not to use with treated lumber due to chemical interaction; verify compatibility with your lumber choice.
Overall, the best roofing nails with plastic washers provide a combination of strong securing power, moisture sealing, and compatibility with common roofing substrates. When selecting among the options above, consider the project scope, the substrate type, and whether you need bulk packs for larger jobs or varied sizes for diverse tasks on the roof deck or wall assemblies.
