Nails vs. Screws: Which Are Best
In order to get a better idea as to which type of fasteners to use when it comes to roofing, you first need to consider the way a roof installation is done. When it comes to installing a metal roof, you must consider that it is likely to expand and contract. The goal of choosing which fasteners to use is to make sure that you choose one that can counteract this effect. In most instances, screws are marginally better than nails, and so should be the first choice you make when the time comes.
Why screws are likely to be better than nails
One of the biggest reasons screws are better than nails when it comes to installing a metal roof is the fact they hold for longer. The fact that they have threads means they grip the anchoring surface of a roof well. Normally when you use cheaper nails, expansion, and contraction result in withdrawal of the nail. This will cause a plethora of problems that range from reduced aesthetic value to leakage. This is why most developers will prefer to use nitronic 50 socket set screws or Inconel hex head cap screws in roof construction.
The issue of cost
One of the biggest disadvantages of using screws is they are more expensive. In addition, it also requires more technical expertise when putting them in place, something that many people are not willing to do. However, you should only consider the long-term benefits when using screws. The fact that you will have fewer problems when it comes to leaks and other issues means you may not have to spend as much as you initially would. This more than covers the extra cost associated with using screws in roof construction.
