Factors to Consider Before Buying Metal Roofing Screws
Dimension and Size
Like any roofing tool, it is essential to find the perfect screw with the appropriate length and thickness. However, it might not be easy to keep all the measurements in your mind. One way that you can make your purchase worth it is to check the surface you want to work on and your preference, whether you want the screw to protrude or not. An oversize screw is of no good, and a smaller one does not provide sufficient holding capacity. The screw size is expressed inches to help you make the best decision. It will also help if you check the shank diameter on the roof. A lower shank sizing can create a holding error and cause an increase in maintenance cost.
To get the right size, we recommend that you check the roofing crew size chart to find different variations that will help with different projects. Besides, some of the products we have listed above contain more than one size and dimension for flexible use.
Weather Performance
Rust is a particular issue of most metal screws. Over time, the screws tend to rust and get weaker. However, rust-proof protection offers considerable protection against rust and corrosion. For example, zinc coating, galvanized coating, and different coating types are handy to protect the screws from harsh weather conditions. Hence, it is best to check for protection if you intend to use the screw for an extended period. Besides corrosion and rust-resistance, you should also check the coating to make sure it matches your roofing sheet.
The Screw Material
Screws can be sourced from different materials. However, the most popular type, especially for metal roofing, is stainless steel. Although there are different types of stainless steel, it will help to know that either will perform considerably better than most material. However, it will help if you check to make sure that the material is rust-resistant. This capacity makes it handy for surfaces that are frequently exposed to water.
Self-drilling or Standard Screw
Surfaces with predrilled holes are easier to attach a screw-on. All you need to do is select a screw with the right length and diameter and fit it into the hole. However, if you are required to drill a new hole, it will help if you choose a self-drilling screw. Thanks to its design, you won’t need to spend time drilling extra holes before use. Self-drilling screws work for different surfaces, including metal. It also sometimes goes by the name drill-point or Tek screws. Either way, it is easier to use than screws that require pre-drilling.
Number of Screws in the Package
Selecting screws can be a numbers game because the more the screws in the package, the more areas you can cover. Hence, it will help if there are assortments of screws of different sizes in large numbers in the package. However, we recommend that you choose quality above quantity. In most cases, numbers advantage don’t always play out well since most either get damaged or are rendered useless during installation. Hence, we advise that you check for quality construction and a little bit of quantity.
Conclusion
Choosing the best metal roofing screws does not need to be a test of knowledge. Instead, it should be about patience and diligence to know every product. However, since you can’t sort through all the screws in the market, it will help if you read our review to make your next purchase worth it.
