What happens here

Begin installing asphalt shingles, starting with a 'starter strip' at the bottom edge of the roof, nailed in place. Line up your first course of shingles over the starter strip. It's crucial to offset each subsequent course of shingles to ensure that the vertical seams do not align, which would create a direct path for water. Use a roofing nailer to secure the shingles, making sure to avoid placing nails directly on the shingle seams. For added wind resistance, you can often add an extra nail per shingle. Continue this step pattern up the roof. For a clean edge finish, use a full shingle as a guide and cut off the excess with a utility knife.

Goal: Apply asphalt shingles to create the final weather-resistant roof surface.

Tools and materials

  • Asphalt shingles — The final exterior roofing material
  • Roofing nailer Rigid — Fastening shingles to the roof deck
  • Roofing nails — Securing asphalt shingles
  • Starter strip — The first course of shingles, providing a finished edge and protecting the eave
  • Utility knife — Cutting shingles to size and trimming edges

What they say

Hide

the shingles. Your shingles will line up on your starter strip, but you have to be sure they're offset. If water gets between these shingles, they'll be on the roof deck or on your felt. When you install your starter strip, this sits under the seam of the shingles, so water that ends up making it into the seam will hit the starter strip and then run off the edge of the roof. So we'll line up our shingle. And now you'll offset your shingles. You want to be sure that you don't have a nail where this seam is going to land, so you'll nail it at the end, but leave this space open so when this sits down, there's no nail at the seam. And you can add an extra nail for wind, and I'll continue this step pattern all the way up the roof. And now you can just take a shingle, lay it down, and use this to cut your edge.
