Standing Seam

Standing seam roof could be considered as one of the most durable and maintenance-free type of metal roof. Standing seam also provide additional energy reduction benefits and will probably last longer than the time you will be living in your home. The Standing Seam roofing panels offer the designer the ability to design or specify various radius roof profiles. This type of metal roofing is made up of vertical panels with two seams per panel that stand us vertically. Once installed, its dramatic shadow lines run continuously from ridge to eave, accenting the pitch and plane of every roof angle.

Standing Seam Installation

Standing seam roof are formed or installed by crimping each adjacent seam together, action that will seal the joint. By doing this moisture and water will be kept away from entering the interior of the building, and will make water run properly to the roof drains. Standing seam panels must be installed in sequence but after an approved underlayment has been placed. Standing seam panels are usually about 18 to 24 inches wide when finished running parallel to the slope of the roof. Attach the panels to the underlayment by using clips or fasteners that will allow the metal to expand and contract accordingly. Using a crimping tool, crimp together both seams and keep repeating the crimping action until all panels are seamed.

There are four basic styles of metal standing seam panels:

  • Mechanically seamed Hydrostatic Panels
  • Symmetrical Mechanically Seamed
  • One Piece Snap-Lock
  • Two Piece Snap-Lock

Walking on metal roofs can be really dangerous and extreme safety measures shall be taken. Metal roofs are really difficult to install on roofs with lots of equipment, vents, chimneys and skylights.

Standing Seam Cost

Standing seam cost will require an onsite inspection to determine the installation feasibility and other related information. Normally, a complex installation will cost an additional 10 percent in material and labor costs. When quoting a metal roof be sure to include delivery, underlayment, counter flashing, soffit and vents, stack covers and fasteners. For example standing seam 29 gauge 12” will have an approximate cost of $2.45 per linear foot while the 29 gauge 16 panel is near $2.75 per linear foot. However, these costs are approximate and might represent the actual costs of standing seam panels.
