When you start your metal roof project, one of the first things that you need to determine is where to place screws on metal roofing. Although many people have the “know how” for this task, the number of screws that you will need to complete your project will depend on several factors. The most obvious factor is the amount of square footage that you are working with. The number of screws that you will need will also depend on the type of roof that you are installing – asphalt, shingles or metal.
Before you start installing your metal roofing, you will want to take a look at your existing roof and determine what type of metal you are dealing with. You will generally be dealing with either aluminum or metal. If you are using metal, you may need to install a special metal screw pattern before installation. In fact, some metals will not support the weight of a screw without a special pattern.
Once you have determined which type of metal you are going to work with, it is time to choose your screws. The type of screws that you use is very important, as they will determine the lifespan of your metal roofing. Nails are generally used for the strongest screws. There are a few different types of nails that can be used for this job including galvanized and pre-galvanized nails. Galvanized nails will be stronger and last longer than pre-galvanized nails.
Once you have the nails chosen, you need to determine what material to use for your roofing. Preferably, you will be using wood for your screw pattern. Wood screws are stronger than metal screws and tend to be more aesthetically pleasing as well. You can also use different types of wood depending on what type of hardware you are wanting to use for your roofing needs. If you are working on an old home, you can recycle old hardware that you find around the house.
If you are starting a new home, or remodeling an existing one, you might want to choose a different type of metal roofing. One option is to use solid wood for the screws that you are going to use. Another option would be to use pre-finished metal screws that are made to accept a wide variety of washers and mounting mechanisms. Screws that are pre-finished have the most durability, but they are also the most expensive option. If you are working on a budget, you may want to consider using pre-finished metal screws in order to save money. A lot of hardware stores will sell pre-finished metal screws at a discounted price if you are buying in bulk.
The last consideration involves the location where you are going to install the screws. If the metal roofing is flat and free standing, you can install them at the bottom, side and top of the rafters. If you are working on a pitched roof or a gable roof, you need to place the screws in the center of the rafters. Make sure that the screws you are using are strong enough to withstand the weather. The key to preventing a break is to make sure that the screws are screwed in tightly. You can do this by placing a piece of cardboard between the screw head and the rafter so that the screws don’t slip.
