Whether you are building a new home, or just refurbishing your existing home, making the right choices when it comes to how and where to put screws on metal roofing can have a great impact on the end result. Screws play a major role in the structuring of metal roofs, and without them, your roof would be very unstable and prone to a whole host of safety hazards. There are a number of factors you need to keep in mind when choosing where to put screws, so you end up with a sturdy, safe roof that looks great, but also performs well.
Knowing where to put screws on metal roofing involves knowing the basic types of metal that are used in the construction of your roof, as well as the various different sizes and types of screws that are available for use in this construction process. For example, standard two-by-four screws are most often used for roofing structures, including maintenance panels, roof boxes, and skylights. However, smaller screws, such as self-locking helical screws, may also be used if you’re working on a low roof or with limited space. The important thing to keep in mind when selecting where to put screws is the load distribution of the structure in question.
As an example, if you are placing a screw on a high ceiling or other structure, such as a skylight or maintenance window, chances are the screw will rest on a lower portion of the roof, which could lead to issues down the line. If the screw continues to rest on the roof after the structure has been built, the weight of the people inside the building may eventually cause the screw to bow and weaken from the weight of the additional weight. In cases such as these, where you need to know the correct location of where to put screws on metal roofing, you may want to consider using lag screws. Lag screws are made out of either nylon or metal and are used specifically for installation on metal roofs. Instead of resting directly under a load, the lag arrangement allows the weight of the people inside the structure to distribute the weight evenly throughout the screw.
Once you’ve figured out where to install screws on metal roofing, the actual process of installing can be a bit more challenging. When installing, always start on the bottom-most rafters or joists first, followed by going up to the top-most rafters. This ensures that there is a good seal between the screws and the roof itself. After ensuring that this is done, you can move on to installing the next sections of metal, finishing with a ridge cap screw as the last piece to secure the roof to the building.
Once you’re done, make sure to check your work for any damage. You don’t want to cut into your metal roofing while it’s still hanging because it will cause even more damage. Also check to see if the panels are installed to the right specifications. If they are not, then the panels won’t lay flat against the roof and won’t protect your house properly. Another important thing to note – don’t forget to anchor your metal roofing to the frame, especially if you live in an area that is prone to high winds.
Overall, learning how to know where to put screws on metal roofing isn’t difficult. It’s simply a matter of finding the right places and doing the work. Metal roofs are usually easier to install than other types of roofing, but because of their weight they can be prone to leaking over time. In addition, they may have more problems from flying debris. Make sure to follow all directions exactly and stay safe while doing so.
