Standing Seam Metal Roof Details - Discover Pros & Cons of Standing Seam -

Standing seam is a descriptive industry term for vertical sheet metal roofing system. Standing seam is one of the most popular metal roofing systems because of its beauty, durability, longevity, simplicity, versatility, and bold looks. Homeowners considering installing a standing seam metal roof on their property, often do so because they like the modern style of raised seams giving their home that bold, contemporary look and feel, along with unmatched durability, longevity, and energy efficiency.

Standing seam is a high-end upgrade from a classic rib style that became synonymous with corrugated metal roofing. Unlike its predecessor, corrugated steel roofing, which is still being widely used today for commercial, industrial and even some residential projects, standing seam has an improved design featuring concealed fasteners. Raised seams, and no roof penetrations helps minimize a chance of a roof leak down the road.

Standing Seam vs. Corrugated Steel Roofing

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 galvalume steel is used for manufacturing of standing seam panels. A 24, and 22 gauge steel can also be used for residential and commercial styles including architectural (requiring a roof deck) and structural (only requiring a roof frame) profiles. A mid-panel stiffening technique is sometimes employed by the sheet metal fabricators, suppliers and manufacturers for a 16 inch and wider standing seam metal roofing 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 Kynar 500 paint finish. this is unlike corrugated metal roofs that are often painted with cheaper acrylic paints.

Loved by Residential and Commercial Architects

Many architects are especially fond of specifying standing seam for new construction and existing roofs thanks to the beauty, durability, longevity, and relative softness with strength and flexibility of metal. Standing seam roofs can also help improve a roofs energy efficiency, as well as help prevent ice dams on a roof.

Standing seam panels can be manufactured from a coated steel, bare and painted aluminum, zinc, copper, and stainless steel. If you live near a coastal area, it is a good idea to opt for an aluminum standing seam roof in order to prevent any corrosion and rusting due to a relatively high concentration of salt in the near-coast air/environment.

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 metal roofing is a bit pricier, but the seams can be locked by a simple snapping of the panels together.

Regardless of the type of system you choose to install, you will have to use manufacturer approved fasteners with every panel during the installation.

How Does a Standing Seam Metal Roof Compare to Metal Shingles?

Standing seam metal roofs generally cost 25% to 35% more to install than metal shingles. This is largely attributed to a more tedious labor necessary to install a standing seam metal roof. In terms of performance, there is no significant difference between the two systems, however the quality of your installation and strict adherence to your systems manufacturers specifications is by far the single most important factor determining longevity and performance of any residential or commercial, high-end metal roof.
