How to Install TPO Roofing over Plywood?
There are certain steps that one needs to follow to install TPO Roofing over plywood. These are:
Step One: Make sure the roof can support it.
A specialist should decide whether TPO material has enough weight and strength because they will know how much pressure each type of roofing material demands.
Step Two: Make sure your roof is clean before starting the installation.
This entails removing any debris, dirt, or even leaves that may cause adhesion issues and a mess later on.
Step Three: In order to have a smooth surface, look for any joints between different sections of plywood.
Make sure all of your plywood is at least 34 inches thick because TPO material can weigh up to 70 pounds per square foot, so anything less will not be sturdy enough.
Step Four: Apply a primer coat and then a layer of adhesive to provide the initial binding between the roofing material and the substrate.
Step Five: Apply a final coat on top of this and allow it to cure completely before returning without fear of moisture or condensation forming beneath the barrier.
This generally requires experienced professional installation by residential, industrial, or commercial roofers in USA because if the TPO roofing is applied incorrectly, it may lead to various problems down the line that you obviously don’t want. Ensure that you use an adequate amount of adhesive, along with nails and screws, to securely fasten the material so that nothing can rip off once installed.
