Standing Seam Roofing Systems
Standing seam is a descriptive industry term for vertical sheet metal panels. It’s one of the most popular metal roofing styles for residential, commercial & industrial buildings, thanks to its durability, longevity, simplicity, versatility, energy efficiency, and its remarkably clean, bold looks.
Standing seam is a high-end upgrade and an undisputed step up in quality and longevity from the classic corrugated and ribbed style metal roofs. Unlike its predecessor, corrugated steel roofing, which is still being widely used today for many commercial, industrial, and even some residential projects, standing seam has an improved design featuring concealed fasteners. Its ingenious design featuring the raised seams, with no exposed screws in the roof, helps minimize the chance of a roof leak down the road.
Standing seam roofs are generally made from thicker grades of steel than corrugated steel roofs. While many corrugated steel roofs are made using a very thin 29 gauge steel, a minimum of 26 gauge G-90 galvanized steel or more commonly galvalume steel is used for manufacturing of standing seam metal panels. A mid-panel stiffening technique is sometimes employed by the sheet steel fabricators, suppliers and manufacturers for a 16 inch and wider standing seam panels in order to prevent “oil canning” of the panels. A metal coil from which standing seam panels are manufactured is usually factory painted with a high-end paint finish.
Standing seam panels are manufactured from a coated G-90 (galvanized) steel, Galvalume Steel bare and painted aluminum, zinc, copper, titanium, and stainless steel. For coastal area, it is a good idea to opt for an aluminum standing seam roof in order to prevent any corrosion and rusting risks arising from the relatively high concentration of salt in coastal and marine environments.
Two Types of Standing Seam:
- A field-locked (mechanically locked) standing seam requires special crimping tools to crimp down/lock the seams during the installation.
- A snap lock standing seam system is a bit pricier, but the seams can be locked by a simple snapping of the panels together.
If you choose to install standing seam roofing system, you will have to use manufacturer approved fasteners with every panel during the installation.
You can get a wide selection of standing seam profiles available in galavanized steel, galvalume steel, and aluminum.
Major roofing suppliers normally have many standard colors available for the fabrication of metal panels in any profile you choose.
A key to a long-lasting metal roof is the quality of its installation. Standing Seam Roofing System required installers with experience and extensive expertise.
