Standing Seam Pros and Cons
3 Types of Vertical Metal Roofing Panels
Standing seam, also referred to as vertical seam metal roofing comes in 3 general product types. Though it is our belief that true standing seam is the only option that should be considered for residential use, you should understand why. With regard to how the metal roofing panels are fastened, it’s important to know the pros and cons in methods commonly used.
Through-Fastened Vertical Metal Roofing
Also called “exposed fastener”, these are sheets of corrugated metal that are laid on the roof and secured to the roof deck with screws. Commonly used on agricultural buildings and increasingly on residences.
Pros: widely available and relatively inexpensive to install
Cons: no built-in allowance for the metal’s movement with temperature change, fasteners can back out or break, susceptible to moisture damage, no interlock, poor quality coatings
Nail Hem Vertical Metal Roofing
Like vinyl siding, these panels have a nailing strip running down 1 side.
Pros: Elongated holes allow for expansion and contraction of the roof panels
Cons: With any improper or deviant fastenings, the allowance for expansion is negated and ripples can appear in the panels, centers of panels lift up during severe wind storms, usually lower-quality protective and reflective coatings
Concealed Fasteners Vertical Metal Roofing
Concealed fasteners and interlocking panels create a complete roofing system.
Pros: Designed with clip fasteners that allow the metal roofing panels to float with expansion and contraction of the metal caused by temperature changes, only concealed fasteners, offer full protection, and quality coatings.
Cons: Requires proper installation by trained crews, or manufacturer-guided DIY installation for lasting performance.
