Can TPO Roofing Be Installed Over Plywood?
The advantages of TPO roofing in the US include its cost-effectiveness, durability, heat and UV resistance, and energy efficiency. Underlayments and insulation are made of plywood, which is a popular roofing material. It is possible to install TPO roofing over plywood, but there are some limitations and guidelines that needs to be followed. We are state licensed roofing contractors and we will guide you how can you install roofing over plywood.
TPO Roofing Benefits
Over plywood, TPO roofing can be installed as a single-ply membrane. Although there are different types of roofing materials available, TPO is preferred due to its cost-effectiveness. Furthermore, TPO roofing is long-lasting and can protect the roof for a few years.
TPO roofing installed over plywood has certain limitations, such as expanding due to temperature changes. Over time, it may cause problems.
The installation of plywood for TPO roofing in the US is not recommended, but contractors can use it if they follow certain guidelines and follow safety precautions to ensure that your property will not be damaged.
Before installing TPO roofing over plywood, consider the following factors
Before installing the system, however, certain considerations must be taken into account. Even with residential roofing repair you should consider proper ways to add TPO roofing to your plywood.
Due to TPO’s tendency to hold moisture, when it gets too hot or too cold, the moisture may damage your roof and cause mold growth.
Keeping the membrane adequately ventilated will prevent condensation from building up under it. Roofs made of TPO are extremely thin.
Therefore, you must ensure that the roof is not damaged or has no holes, which can easily go unnoticed until it is too late.
The long-term durability and strength of TPO Roofing will be compromised if it is installed on plywood.
The edges of TPO roofing will eventually start peeling off or curling away, even if there are no problems initially. Additionally, TPO roofing membranes will easily start coming off once they start aging, as well as from constant weather conditions such as rain and wind hitting the roof hard.
To make your roof more efficient and to protect it from weather elements, consider these factors carefully before installing TPO roofing. Other roofing materials don’t provide the same level of energy efficiency and cost as this material.
When choosing between a single-ply membrane and multiple ones, be aware of the drawbacks and limitations. Here are some important things you need to know about TPO roof installations
What is the best way to install TPO roofing over plywood?
In order to install TPO roofing over plywood, certain steps need to be followed. These are:
Step One: Make sure the roof can support it.
Specialists know how much pressure each type of roofing material requires, so they can determine whether TPO is strong and heavy enough.
Step Two: Make sure your roof is clean before starting the installation.
The process involves removing any debris, dirt, or leaves that may cause adhesion issues and a mess later on.
Step Three:
Look for any joints between different sections of plywood if you want a smooth surface.
Plywood should be at least 34 inches thick because TPO material can weigh as much as 70 pounds per square foot. Anything less will not be sturdy enough.
Step Four:
In order to create the initial bond between the roofing material and the substrate, apply a primer coat and then a layer of adhesive.
Step Five:
Finally, apply a final coat to prevent moisture or condensation from forming beneath the barrier. Allow it to cure completely before returning to the area.
Residential, industrial, or commercial with the best roofing contractors in Pinellas need to have experience installing TPO roofing correctly because if it is applied incorrectly, it may lead to a number of problems down the road that you obviously do not want. It is also important to ensure that sufficient adhesive, nails, and screws have been used to ensure that the material is securely attached so that nothing can be removed once it has been installed.
