There are many inexpensive options when looking to replace your roof. However, if looking to make the most out of your investment a standing seam metal roof could be the right choice. Read on to find out more about the advantages and disadvantages to determine if it is right for you.
What Is A Standing Seam Metal Roof?
Traditional metal roofing is installed by huge ridges. Each panel is locked at the seams using nails. Then caulk is used to seal the nails at the seams to prevent leaks and provide insulation. However, standing seam metal roofs us different installation methods than traditional metal roofing. There are four kinds of standing metal roofs and they are mechanically seamed, nail-hemmed, snap-locked, and exposed fasteners.
Mechanically Seamed
Clips and hidden fasteners give these a very clean and uniform appearance. Roofing contractors will often recommend this style as it is one of the fastest to install. After installing on the roof, they will use a specially designed machine or hand crimpers to mechanically seam them together. Mechanically seamed systems are especially valuable when it comes to low sloped roofs. Generally, aluminum or steel standing seams will be used in this application.
Nail-Hemmed
These standing seam roof panels are similar to vinyl siding panels. They have a raised interlocking system on the edges with a hidden fastening channel along the edge. These channels have elongated holes allowing the fastener to lock the two panels together. The most common materials used to produce these are aluminum and stainless steel.
Snap-Locked
These are the fastest and easiest to install of all standing seam metal roofing panels. In addition, this style is ideal in hot environments as they allow movement due to thermal variations. Snap-lock systems are installed by using clips secured to the roof deck to hold the panels in place. When compared to mechanically seamed panels there is no need for additional crimping. Snap-lock metal roofing is available in galvanized iron, aluminum, and steel.
Exposed Fasteners
These are the cheapest standing seam metal roof panels on the market. Traditional metal roofing uses caulk and nails to lock the metal panels together. This standing metal seam type overlaps and locks them together in a similar appearance. However, in place of caulk and nails, this variant uses screws with washers or rubber grommets to create a weatherproof seal. The major downside to these is they require screw replacement after 10 to 15 years. In addition, they also rely on regular maintenance when compared to other metal roof types.
Advantages of Standing Seam Metal Roofs
Longevity, when compared to traditional roofing materials, is the biggest advantage of a metal roof. Standing seam metal roofs last 50 years or more which results in much longer warranties on the metal roofing panels. Standing seam metal roofs can handle the toughest extremes in weather and are less likely to create ice dams. This means they are especially helpful in climates that receive a lot of snow. Standing seam metal roofs are also incredibly energy efficient making them a smart choice for the environmentally savvy. They are excellent at reflecting and dissipating the sun’s rays. They also come in a wide array of materials and colors to match the aesthetic of your home. In addition, they offer a sleek, consistent, and modern look to your home.
Disadvantages of Standing Seam Metal Roofs
The higher cost is the biggest drawback to standing seam metal roofs. They can be significantly more expensive than more traditional roofing materials, especially when factoring in a labor-intensive installation process. This also makes them much harder to replace or repair if the need arises. However, flat roofing structures do not allow them since these do not promote water to adequately drain. Standing water on metal roofing can lead to premature aging, color changes, and failure of the system. In addition, it is much harder to find contractors who have experience with standing seam metal roofing. When looking for a roofing specialist to do these jobs make sure they have experience with installing them.
