Metal roofing systems are among the most popular to use when constructing roofs in Schertz . Metal roofing is known for its longevity with some lasting 40 to 70 years. Asphalt roofing by comparison typically lasts 12 and 20 years. Metal roofing is also highly durable, resisting impacts and handling wind gusts that reach 140 miles per hour. Metal roofs are fire resistant, energy efficient, and are 100% recyclable.
If you are considering a metal roof, then you will notice a few key variations. Metal roofs tend to have standing seams or screw-down styles. There are also some variations in gauge of the metal.
Screw-down metal roofs involve the panels being fastened to the roof directly through the metal and into the framing or deck. The fastener is exposed with this choice and that can cause problems.
Screw-down metal roofs tend to be more affordable than standing seam. This is due to their ability to work with lower-quality paint systems, thinner gauge panels, fewer accessories, and wider panels. They do not require time-intensive fabrication and perform fairly well. Finally, screw-down metal roofs have a traditional appearance that some homeowners prefer.
The disadvantages of screw-down metal roofs are multiple penetration points, one at every fastener. There can be issues related to the fasteners however. There are problems such as UV degradation and roof screws coming out. This happens when weather changes and causes the metal roof to expand and contract.
The other main type of metal roofing uses a standing seam, which conceals the fastener. This type of roof has vertical risers with broad and flat areas between them.
The lack of exposed fasteners is a benefit of standing-seam metal roofs. This is the preferred method as there are no visible holes so that water can find its way in. Standing-seam roofs also tend to allow for more thermal movement. They require less maintenance than screw-down and last longer. Many people also prefer the sleek and modern appearance of these roofs.
On the other hand, there are fewer qualified contractors who can install a standing-seam metal roof. The installation process is more labor-intensive, and it costs more. You also cannot use standing seams on a lower sloped roof. Installation of a metal roof below a 2/12 pitch roof is not recommended.
In addition to standing-seam and screw-down metal roofs, there are different metal gauges. Gauge refers to the thickness of the panel you use on the roof. A higher gauge number indicates a thinner material. For residential, the minimum is 29 gauge, with 26 gauge being suitable but we use 24 gauge on our roofs. The reason why it stands up to the hail and weather like we have here in San Antonio. Different roofing companies in San Antonio will use different gauges of metal. So be sure to find out what gauge the roofing company is using to compare apples to apples. You should also look at the decimal thickness or rely on your roofing contractor.
