Many homeowners who are considering installing metal roofs over plywood will often ask the question, how to install metal roofing over plywood, because over time it can be a more expensive option than other options for roofing. In addition, when talking about how to install metal roofing over plywood, many people often use an installation method known as hot lamination. There are a few differences between this installation method and others that might be of interest to you.
One of the most important things to know in order to decide how to install metal roofing over plywood is that each material has its own type of coating that must be applied to ensure that it will bond properly. There are two common ways that this coating is applied to metals – either using acrylics or with zinc. It’s important to remember that zinc will actually provide a weaker bond than the other option, but if the surface is smooth, then the zinc may provide the best overall protection. To make sure you have a smooth surface, you will want to sand the roof prior to application.
When talking about how to install metal roofing over plywood, one of the main differences is the cost. If you are looking at doing the job yourself, it’s important to understand that metal roofing installation is much more costly than installation of other types of roofing. While the materials used for installation of metal roofing are definitely more expensive than those used for installation of other types of roofing, they are far more durable. This means that they will last longer without having to repair them on a regular basis, which is something that you can appreciate given the fact that it can be quite a long way until you need to replace your metal roofing.
One of the biggest concerns when learning how to install metal roofing over plywood is the fact that you do not want to use nails or screws when attaching the roofing panels to the house. Metal is quite susceptible to getting damaged by the elements and wind and rain. Even though metal roofing over plywood is generally pretty weather resistant, there is always a chance that it could get damaged. Make sure you use the right type of screws and nails for the type of metal roof you will be installing over.
Another important consideration in learning how to install metal roofing over plywood is how to install metal roofing over asphalt shingles. Asphalt shingles are typically very smooth and flat. The grooves in the asphalt are usually not ideal areas for the fastening of metal. You need to be especially careful when working with these types of shingles because you obviously would have a much harder time attaching it to the roof properly.
One last thing to keep in mind when learning how to install metal roofing over plywood is to make sure you are going to be using the proper screws and nails for the job. Using the wrong screws could potentially damage your metal roof. Nails that are too long or that don’t fit properly could also cause damage as well. If you are learning how to install metal over plywood, keep all these factors in mind before proceeding.
