Where To Place Screws On Metal Roofing
Whether you’re installing vinyl or metal roofing, you have to know the right way of placing screws so that your installation looks good and holds together for many years. The proper installation of metal roofing screws is not just about getting the screws to fit snuggly; it’s also about making sure that the screws have a good grip and are able to hold onto the roof material properly. If you’re not sure about how you should go about installing screws on metal roofing, you should talk to a professional roofer. They will be able to help you choose the best type of screws that you need, which ones to avoid, and even show you a helpful trick or two that you can use to make your job go a little faster.
Before you even start installing your roof, you need to choose the right location for where to put your screws. A metal roofing expert will be able to tell you what type of screws are best for your particular application, and will show you where to place screws on metal roofing that are going to have a harder time holding down and holding in place. If you’re installing just one or two shingles, then you’ll probably want to anchor each one down with two screws.
You might want to choose a screw pattern called metal purlins because they look kind of “cool.” Metal purlins look like small, smooth pebbles, and they’re actually very easy to install on metal roofing. You simply need to attach the screw to the ridge cap and then to the shingles themselves. Metal purlins are available in different widths, so you can use them in a variety of roofing applications.
Another type of screw pattern that is popular with metal roofing experts is the cap-and-mortise joint. Using a cap-and-mortise joint offers you two advantages: it’s easily installed and it holds screws tightly in place. The cap-and-mortise joint looks like a combination of a half-inch circular cap and two long nails, but instead of using long nails, the nails are pre-sized. You can install this type of screw pattern in any configuration you like, although the easiest way to use this pattern is to start with two nails and thread them through the holes in the cap and the ridge cap, securing the screws in place with metal tabs or clips.
If you’re installing metal roofing on a solid wood roof, then the chances are that you’ll be working with a solid wood shingle. If this is the case, your best bet is to stick with the traditional screw pattern called tongue-and-groove. This pattern looks something like a half-inch round wooden peg, with long and short nails spaced evenly on the shingle. When installing the screw pattern, make sure that the shingles are installed directly over the nails and that the caps and screws are directly over the shingles. This is one of the most reliable ways of installing a screw pattern onto a solid wood roof, and it gives you the advantage of using long nails without fear of them coming out.
You might also want to consider installing a metal roofing where the roofing is not directly attached to the house. For instance, you might choose to install a metal roof on a shed, garage, outdoor storage building, or even a greenhouse. Installing metal where there’s no underlying structure makes installation much easier than with traditional materials. However, installing screws where the metal meets the earth can cause damage to the soil underneath the structure, so it’s important that you keep the installation as dry as possible. A little rain can easily ruin a perfectly good installation, so take care when installing screws on metal roofing where the structure is not attached to the house.
