Locating Where To Place Screws On Metal Roofing

There are many things to consider when you decide where to place screws on metal roofing. If you are installing roofing shingles, the screws that you use need to penetrate the shingles and the metal to which they are attached. This means that your screw pattern has to be precise. The types of screws that are most often used are screws with hex heads and threads. The most effective metal roofing screw pattern involves the use of captive bolts with a thread bar.

You can choose to use solid wood screws if you so desire. The problem with using solid wood screws is that they tend to rot. Bolts, whether they are solid wood or metal, cannot stand up against the inherent strength of metal purlins. Where to place screws on metal roofing depends on the location of the screw. If the screws are to be placed on the exposed edges of the metal purlins, then you need to drill the screw holes in these areas so that you can install the screws. If the screws are to be placed where the purlins join the roofing, then you will not need to drill any holes.

To ensure that the screws you use penetrate the metal roofing as deeply as possible, use a ratchet wrench. Start by loosening all the nuts and then unscrewing them. Drill through the sheet metal as much as possible, making sure to get into all the places where screws are to be used. Make sure that you install the screws all the way through the sheet metal. If you have nails, you will want to place them where the ratchet wrench will hit them.

Another consideration for where to place screws on metal roofing is whether the screw pattern is right for your application. For a straight or flat roof, using a standard eight-inch screw pattern will work. However, if your roof has sloping angles, then using a screw pattern that is more than eight inches will likely not provide you with the best results. Using a screw pattern that is too wide could possibly damage your metal roofing.

On flat roofs, such as those that slope towards the garage, installing screws in the wrong place could result in your metal materials buckling or breaking. In these situations, using a flat or linear pattern will give you the best results. However, if your metal roofing is to be mounted over a concrete slab, you will want to choose a screw pattern that allows for expansion and contraction with changing temperatures. If you are installing over concrete, then you should make sure the pattern uses standard eight-inch screws.

The location where to put screws on metal roofing will vary depending on the amount of expansion and contraction that occurs during the year. If your metal roofing follows the normal growth pattern seen throughout your home, then you can safely use standard eight-inch screws. However, if your roofing grows and expands at different rates, such as if it is exposed to strong sunlight for long periods of time or if you live in an area where ice is common, you may want to consider using stainless steel screws that allow for expansion and contraction. Regardless of which type of screws you use, you will find that using standard screws will ensure that your roof is sound and stable for years to come.
