Step 7 - Tar Paper
Materials required: One roll of tar paper
This step is not needed, but it will help your pipe last longer. The plywood you used in the last step is not waterproof. The skatelite that you will put on the top later will be, but some water will seep in, the tar paper will stop this water from getting to the plywood. Its pretty self explanatory, just use a staple gun and cover all of the plywood with the tar paper.
