How to Install Shiplap Log Siding

Updated February 21, 2017

Shiplap log siding is a type of wood siding that is installed vertically or horizontally. The horizontal installation is called bevel and the vertical installation is called board-and-batten. There are variations within these styles, including various sizes and styles. Installation of all of these different types follows the same procedures. The most important part of the installation process is prepping the outside of the house for the siding.

Measure the height and width of each side of the house to get the total square footage. Multiply the length by the width of each side and add the four sides together to determine how many pieces of siding will be used for installation. Increase the total by 15 per cent for cuts that will need to be made.

Wipe down each side of the house with a rag to remove any dirt and debris that is on it. Roll out a vapour barrier and begin installing it over the top of the sheathing. This barrier comes in a plastic roll and can be purchased at a hardware store. This will prevent moisture from getting into the house. Using a staple gun, insert a staple every 12 inches throughout and continue rolling the plastic around until the entire house is covered.

Locate all of the studs with a stud finder and mark on the house with a marker where those are. Line up the first piece of siding horizontally at the bottom of any corner of the house. Leave a 1/8 inch gap from the side and bottom for expansion and nail it in place with 1- 1/2 inch siding nails and a hammer. Insert a nail along each stud.

Line up the second piece of siding over top of the first. Overlap the pieces by one inch and insert the nails into the overlap at each stud. Line up the next piece and install it in the same manner. Continue up the house until the first row is complete.

Line up the second row and leave 1/8 inch gap for expansion between the two rows. Install the second row just like the first and continue around the entire area of the house until the siding is covering everything. Cut the pieces to size with a circular saw if necessary at the ends of the house.


Always wear safety goggles when working with a circular saw to prevent injury to your eyes from flying pieces of wood.
