PVC roofing can be installed by following traditional roofing installation techniques. The only difference in the installation of your PVC roof is that the material you use is PVC, in contrast with normal roofing shingles. Installing a PVC roof has environmental advantages to other types of roofs. The process, tools and materials for this job are described below. You will need an assistant to help you with the installation.
Step 1: Preparing
You will need to rent a dumpster for this project because you will need to toss the old roofing materials. This can be rented in most communities from the waste collection department. Be sure to have the dumpster delivered and placed in an area of your yard, under tarps that makes it easier to catch the loose materials that you remove from the roof.
You will need a ladder that is tall enough to allow you to easily climb on your roof in order to remove the existing shingles. This ladder should be purchased, or borrowed from a neighbor, and inspected to make sure that it is durable enough to accommodate your weight and allow you to accomplish this task. Climb on the ladder and remove the roofing material with a hoe.
Step 2: Take Apart the Roof
Use the shovel or hoe to remove the roofing material. Work carefully when at the edge of the roof to prevent injury. You should wear safety glasses while you work since a lot of loose material will be flying around. The material should be tossed into a waste receptacle below you while you work.
You will need to get on your knees and remove all of the loose nails and other materials that is remaining on the roof. This is a tedious process that will take time and require you to carefully go over every inch of the roof to remove the material.
Step 3: Install Tar Paper
Roll out tar paper on the roof. This will act as a barrier to keep water from leaking through the roof. The tar paper will be affixed to the roof using a staple gun. Be sure to properly cover the entire roof. Do not leave any gaps or exposed areas because that will cause roof damage and leakage. Work slowly and be precise.
Step 4: Attach the PVC Shingles
Working in rows attach the PVC shingles to the roof. The shingles should have a lip or attachment that will allow you to nail them down on a nailer strip that you installed over the tar paper. Work carefully in order to attach the entire row before moving on to the next. Once the PVC shingles are in place, attach the flashing and other elements of the roof to complete this project.
Any roof repair will take several days to complete so be sure to give yourself plenty of time to complete the work.
