Which metal roof is right for you? in Columbus

Snap Lock

Snap  Lock Panel is the most commonly installed type of standing seam metal roofing in Columbus.  Unless specified otherwise, this will be the default standing seam in Columbus Metal Roofing in Columbus that metal roofing contractors will recommend. It is long lasting and  far less labor intensive, making it more economical to install. This  system is attached with fasteners at the top, then clips are hidden  along the sides of each panel to allow for thermal expansion and secured  along the sides. The primary application is for roof slopes above a 15  degree angle or steeper and will handle most residential wind loads up  to 200 MPH. Finishes are available in Kynar 500 (PVDF PolyVinyliDene Fluoride) or SMP (Silicone Modified Polyester) and is available in 24 gauge or 26 gauge galvalume steel. 


Mechanical Seam

 The  Mechanical Seam Panel is the most durable, water tight, wind  resistant,, and structurally sound standing seam roof system on the  market. It also is very labor intensive, making it one of the most  expensive. It comes in any width between 9 1/2" and 19 1/2" with a 1  1/2" and 2" standing seam and two separate levels of water tightness.  The single lock crimps the top panel's leg over, creating a water-tight  seal. The double lock is clamped together with a machine, creating an  extra tight seal to keep out water and withstand extreme wind loads. The  panels span over open framing up to 4.5 ft with 24 gauge metal, and up  to 5 ft with 22 gauge metal, while maintaining waterproof integrity.  This system also uses a hidden clip which allows for the thermal  expansion of the panel. Once the panel has been double locked, changing a  damaged panel is no longer an option. This means the entire section  must be replaced. 

Snap Batton

 The Snap Batten system is used primarily for curved, arched, or vaulted  roofs. This system uses a hidden interlocking clip that fastens the  panel and the batten strip to the roof while allowing for thermal  expansion. It is available in virtually any width. The panel can be  either straight, concave,  convex, or any combination of these patterns.  This panel has excellent wind load performance and when curved, resists  wrinkling. This roof system is the most labor intensive of all the  systems and requires the highest level of expertise. 

Corrugated

 The corrugated system is the most economical of the metal roof family. A  thinner gauge and more efficient use of metal to cover the roof area  requires less steel per square foot. This characteristic lowers the cost  of the materials, labor, and transportation. Due to the low cost, this  product  is commonly used in agricultural structures, churches and  residences. It has very high wind load resistance and can be installed  over open framing spanning up to two feet. The sides of the panel  overlap giving the panel a seamless look. An anti-siphon groove prevents  water from leaking through at the seams. The corrugations prevent "oil  canning" (wrinkles in the metal) and when the fastener is placed in the  ridge, this raised area keeps the fastener hole out of the water  channel. Since the fastener penetrates through the panel, it relies on a  rubber grommet between the screw and the panel to maintain water  tightness. This washer usually lasts about ten years and will need  serviced. The finish on corrugated panels has the same energy star  rating as all other metal roofing products, but is only offered in a  Silicon Modified Polyester (SMP) finish that is prone to fading. 

Screwline

 The screw line system (also referred to as nail line panel) is the most  economical standing seam roof type that does not require fasteners  penetrating the panel and has the same appearance of the snap lock. The  rib measures 1 1/2" high, panels are 24-26 gauge galvalume steel with an  SMP finish. This roof is usually found on industrial buildings,  warehouses, and other large commercial buildings. Its price falls  between that of corrugated and standing seam roofs. The key to the great  value in this product is a combination of thinner gauge metal, the SMP  finish, and the use of a slotted fastener hole in lieu of a separate  clip. This allows for a quicker installation and lower overall labor and  material cost. The panel featured in the above photo has the striation  option which are tiny bends in the flat of the metal that hide oil  canning (wrinkled looking).  This is especially important when using the  thinner 26 gauge metal
