There are numerous types of roofing available, including metal roofing. Metal is known for its affordability and versatility as a roofing material. Even within the category of metal roofing, there are numerous types of roofs. The most common division is screw down roofing vs standing seams. Take a closer look at each to better understand the difference.
Screw-down metal roofing is the type of metal roofing that was used right when this material first became an option for roofs. You may also see it called through-fastened or exposed fastener since it relies on screws to attach the metal to your roof. For screw-down roofing, the metal used will typically be hardware-store grade. The fasteners include neoprene washers to discourage leaks.
Standing-seam metal roofing relies on vertical panels that have dual seams to connect every panel. This type of metal roofing has a very striking appearance thanks to its shadow lines that you can see running from the eaves to the edges. It is also durable and strong. Originally, standing-seam roofing was primarily used on structures where the roof had several levels. Eventually, however, its popularity spread to other applications as well thanks to high-performance, durability, and minimal maintenance.
Given its nature, screw-down metal roofing is cheaper than that with a standing seam. It is also quicker to apply, saving you on labor costs. The disadvantages arise in terms of maintenance as this type of metal roofing is more likely to experience problems due to age. It is also much more likely for the screws to be negatively affected by factors like weather since they are exposed. The potential for neoprene washers to fall out or fasteners to get rusty increases the chances of leak. Additionally, the fasteners tend to back out eventually since the metal will expand and contract as temperatures fluctuate.
There are numerous other advantages to screw-down metal roofs, including the fact that this is still more common, making it easier to find a contractor with the tools and skills to install it. Installation is also nice and easy since there is no need to seam two panels together. Going back to the more affordable pricing of screw-down metal roofs, this comes from the use of wider panels, thinner gauge panels, and fewer accessories to purchase.
As mentioned, standing-seam metal roofs tend to have great performance, requiring minimal maintenance, and lasting a long time. These roofs tend to last between 30 and 50 years. One of the biggest advantages of standing seams over screw downs is that there are not any exposed fasteners. Instead, the screws get hidden underneath the roof panels, eliminating both functional and aesthetic drawbacks.
Additionally, standing seams are very easy to install. In some cases, standing-seam roofs can be installed right over the current roof saving a great deal of time and reducing the waste produced by your roofing project. We usually recommend complete tear off of the existing roof before installing a new metal roof however. Standing-seam roofs also do even better than other types of metal roofs when it comes to reflecting heat. That results in a greener home that requires less electricity to stay cool.
