Installing the Top Row of Vinyl Siding

Quck answer

To install the top row of vinyl siding, follow these steps:

1. Measure the length of the top row and cut a piece of siding accordingly.

2. Slide the piece into the starter strip, ensuring it is level.

3. Secure the siding using nails or screws, making sure to leave a small gap for expansion.

4. Repeat the process for the remaining pieces, overlapping each one slightly.

5. Use a snap lock punch to create locking tabs on the top edge of the siding.

6. Install J-channel along the top edge to provide a finished look.

7. Trim any excess siding using a utility knife.

8. Finally, secure the top row of siding by nailing or screwing it into place.


Homeowners can enjoy the convenience of vinyl siding, which eliminates the need for frequent exterior painting. Vinyl siding is installed using a channeling system, where the bottom of the first piece of siding fits into a channel to hold it in place. The top edge of the first piece is nailed down and contains a channel to secure the next piece. This process continues as the siding is installed up the side of the house. However, some adjustments may be necessary for the installation of the top row of siding.

Step 1

Measure the remaining gap at the top of the wall.

Step 2

Mark the vinyl at the appropriate spot for cutting to ensure a proper fit. It is important to leave the bottom edge intact so that it can be secured into the row of siding below. Therefore, any cuts to adjust the height of the vinyl siding must be made from the top.

Step 3

Create a score line at the marked spot on the vinyl siding and break off the excess by folding the vinyl along the score line.

Step 4

Insert the vinyl siding into the lower siding and secure the top with 3D nails that match the color of the siding. Since you have removed the channels at the top, you will need to nail directly through the siding instead of using the designated channels used in the lower rows. Keep in mind that nailing without the channels may restrict expansion, so space the nails six to eight feet apart.
