People rarely think of the impacts the slope of your roof has when installing exposed fastener metal panels. This is because there are so many other details to consider when doing any type of construction project, such as securing the panels, making sure all materials meet building codes, and ensuring that the structure can support the weight of the panels. However, the angle or slope at which your roof slopes plays a major role in how easy, or difficult, it is to install your exposed fastener metal panels. It affects everything from the amount of effort required to secure the panels to the type of fasteners you need to use.
On a steeply pitched roof (greater than 4:12 slope), fastening is more difficult because steeper angles mean there is less cushion for the fasteners to bite into and secure. This means that you need to use longer fasteners, such as self-tapping hex head screws, which can penetrate deeper into the substrate for a better grip. A steeply-pitched roof also requires an adequate amount of sealant between the panels and the underlying substrate in order to create a watertight seal.
On a shallow pitched roof (less than 3:12 slope), it is still important to use self-tapping screws because they don’t require pre-drilling. However, the longer fasteners are not necessary on the shallow pitch, so you can save time and money by using shorter fasteners. Additionally, less sealant is required on a shallow slope because the panels are more stable and less likely to move due to weather or wind forces.
For roofs with extreme slopes (greater than 7:12), self-tapping screws may not be suitable as they may not have enough gripping power to stay in place. In such cases, it is advisable to use lag screws with washers and sealant for greater stability and watertightness. It is also important to install fasteners along the entire length of every panel, rather than focusing only on the seams, in order to create a more secure installation.
Understanding the slope of your roof is essential when it comes to roof repair. By taking into account the angle and pitch of your roof, you can ensure that your repair job will be safe, secure and long-lasting. Expert roof repair services in Phoenix AZ will help you determine the correct way to fix your roof without problems.
Regardless of roof slope angle, it is important to use the right fastener for exposed metal panel installation. The most common types are self-tapping screws and lag screws, which both have their own advantages and disadvantages depending on the situation. For example, self-tapping screws can be easier and faster to install, while lag screws provide a much stronger connection that is better suited for extreme weather conditions.
