Overlapping roofing felt protects the roof deck from seepage, wind-driven precipitation, and ice-dam back-up. For roofs with slopes greater than 4/12, a minimum overlap of 2-inches between courses is required. A greater overlap provides more protection but may cause problems with spacing and fastening upper courses relative to sheathing seams.

On low slope roof decks between 2/12 and 4/12, the recommended overlap for roofing felt is a minimum of 19-inches. The first course or starter strip is a 19-inch width of felt, and the next course overlaps it fully. Successive courses repeat the 19-inch overlap.

Where the felt isnt long enough to complete a course there should be a minimum of a 3-inch overlap. Ridges, hips, and valleys should overlap at least 6-inches beyond the centerline, and there should be a similar overlap below vent pipes and utility stacks.

When Should I Consider Using Plastic Round Cap Roofing Nails

Asphalt Composition Shingles

I’m getting ready to shingle a roof for a shed/outdoor office and I’m confused on if/when I should use plastic round cap roofing nails:

I haven’t seen these used in any instructions or videos. Are these nails a gimmick? Or are there clear advantages to using them?

Those nails are used only for holding down the roofing underlayment. They excel at doing so whether it be old school tar paper, or the newer more durable, hi tech roof underlayments.

  • The prior version of these was amusing – instead of the plastic piece, you had a tin can lid. EcnerwalMay 25 ’15 at 21:45
  • Is there a specific reason for using those on the underlayment in roofing? I have been involved in several roof jobs and have never seen them used. The underlayment just gets rolled out and you start tiering shingles and nailing with the standard nails or staples.May 25 ’15 at 23:28
  • 2@FiascoLabs They reduce the amount of tearing if the underlayment is exposed to wind before it’s fully shingled – with just nails, the heads much more easily tear right through. These spread the load over a much larger area. Not that much of an issue if using ice and water shield rather than tarpaper/felt ^) EcnerwalMay 26 ’15 at 1:46
  • They’re actually not only used for roofing – they’re useful for insulation board too. I actually own a pneumatic cap nailer that I picked up when I was doing vinyl siding. CominternMay 26 ’15 at 2:43
