The right asphalt felt roofing supplies depend on whether you need underlayment, fasteners, or a localized waterproofing repair. Tarco #15 asphalt felt is the direct choice for traditional felt underlayment; the two nail options are for fastening it, while the tape and membrane are repair or flashing materials rather than standard felt rolls. The selections below suit different project needs, so check the dimensions and application before ordering.
| Product | Best For | Key Detail |
|---|---|---|
| Tarco STD15 Asphalt Felt | Traditional felt underlayment | #15 asphalt felt, 36 x 144 |
| One Stop Outdoor Store Roofing Nails | Longer fasteners | 2-inch galvanized nails |
| Swpeet Roofing Felt Nails | Bulk fastening | 300 lacquered steel nails, 1 inch |
| Blue Waterproof Roofing Felt Tape | Small-area sealing | Self-adhesive asphalt tape |
| BXI SBS Membrane | Flashing and waterproofing | 13-inch-wide torch-on roll |
Tarco STD15 #15 Asphalt Felt
Tarco STD15 is the most direct match for shoppers looking for asphalt felt roofing material. The listing identifies it as #15 asphalt felt and gives its dimensions as 36 by 144. It is the option to consider when the project calls for a traditional felt roll rather than a patching tape or a modified-bitumen membrane.
Best for: Roofers or homeowners who need asphalt felt underlayment in a roll format. It was selected because it is the list’s only product explicitly identified as asphalt felt. The listed item weight is 32 pounds, and its country of origin is the United States.
Check before buying: Confirm that the roll dimensions and felt specification meet your project requirements. The supplied product details do not explain installation instructions or intended roof types.
One Stop Outdoor Store 2-Inch Roofing Nails
These professional-grade nails are 2 inches long and galvanized. The product details say they are used to fasten roofing felt, asphalt shingles, and insulation board. Their diamond points are intended to help with penetration, making them a longer-fastener option among the listed supplies.
Best for: Buyers who need 2-inch nails for a roofing application and want galvanized fasteners. They were selected because the listing specifically names roofing felt as an intended use.
Check before buying: The listing provides a quantity of 50. Confirm that this quantity and the 2-inch length suit your fastening plan; the available details do not specify nail-head dimensions or recommended spacing.
Swpeet 300-Piece Roofing Felt Nails
Swpeet’s kit contains 300 lacquered steel nails, each listed as 1 inch or 25 millimeters long. The nails have round, flat heads, pointed ends, and regular lines along the shank. The listing also describes diamond points and a large-diameter shank intended to support penetration and holding power.
Best for: Buyers who want a larger nail quantity and a shorter fastener than the 2-inch option above. It was selected for its explicit roofing felt use and stated 300-piece count.
Check before buying: The 1-inch length may not match every assembly or fastening requirement. Verify the needed length for the roofing materials and surface before choosing this pack.
Blue Waterproof Roofing Felt Tape
This 100-by-300-centimeter roll is described as self-adhesive polymer-modified asphalt with an aluminum foil layer. It is designed for sealing and repair applications, including roofs and gutters, and can be cut to size. The listing describes it as resistant to water, heat, and cold.
Best for: Small-area sealing or repair work where a peel-and-stick tape is appropriate. It was selected as a supplementary roofing supply, not as a substitute for a full roll of conventional asphalt felt.
Check before buying: This is tape, not sheet underlayment. Review the application surface and project instructions before relying on it for a roof repair.
BXI SBS Modified Bitumen Membrane
The BXI roll measures 13 inches by 8.2 feet and is listed as 1/8 inch thick, with 8.86 square feet of coverage. Its SBS polymer-modified bitumen material is described as flexible and intended for torch application. The product is positioned for waterproofing and sealing, including flashing and foundation applications.
Best for: Buyers seeking a narrow membrane for flashing or targeted waterproofing rather than ordinary felt underlayment. It was selected because it is an asphalt-based roofing material with a clearly stated roll size and use case.
Check before buying: The listing describes torch application, so this is not a peel-and-stick felt roll. Follow appropriate product and job-site safety guidance when working with heat.
Buying Guide: How To Choose Asphalt Felt Roofing Supplies
Do you need felt, fasteners, or a repair product?
Start by identifying the job. Tarco is the direct choice for asphalt felt underlayment. Roofing nails are for fastening materials, while the tape and SBS membrane serve sealing or flashing roles. These products are not interchangeable: a repair tape does not provide the same format as a full felt roll.
Which nail length and quantity should you choose?
Compare the fasteners with your project specifications before ordering. The One Stop Outdoor Store option is 2 inches long and comes in a listed quantity of 50. The Swpeet option is 1 inch long and includes 300 nails. Quantity alone does not determine suitability; match length and fastener type to the materials being secured.
When is tape or membrane a better fit?
Choose the tape when the task calls for a cut-to-size, self-adhesive sealing material. Consider the BXI membrane for a narrow, torch-applied flashing or waterproofing application. Check the required application method and coverage; the BXI listing gives 8.86 square feet of coverage, while the tape dimensions are 100 by 300 centimeters.
What should you verify before ordering?
Confirm roll dimensions, coverage, material type, fastener length, quantity, and installation method. Also compare product instructions with local building requirements and the specifications for your roof assembly. If a project calls for a specific felt grade or fastening pattern, verify that the listed product matches it rather than assuming all asphalt-based supplies meet the same need.
