There are numerous types of roofing available, including metal roofing. Metal is known for its durability 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 seam. Take a closer look at each to better understand the difference.
Screw-down metal roofing is the type of 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 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 roofing is more likely to experience problems due to age. The screws are exposed making it more likely that they are negatively affected by the weather. 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 it is more common, making it easier to find a contractor with the skills to install it. Installation is also nice and easy since there is no need to seam two panels together. As far as 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 in Austin. A big advantage of standing seams over screw downs is that there are not any exposed fasteners. The screws are hidden underneath the roof panels, eliminating both functional and aesthetic drawbacks.
Additionally, standing seams are very easy to install. Standing-seam roofs can be installed over the current roof saving a great deal of time and reducing waste by your project. We recommend complete tear off of the existing roof down to the deck before installing a new metal roof however. Standing-seam also does even better than other types of roofs when it comes to reflecting heat. That results in a greener home that requires less electricity to stay cool.
