Aspects Of ARCO'S Roofing System

Lifespan

Corrugated metal roofs are installed with fasteners that are exposed to the elements. The screws will eventually back out and the holes in the panels will enlarge and they will leak. All corrugated metal roofs need to have their fasteners inspected and tightened at least once a year. ARCO standing seam metal roofs do not require this type of routine maintenance thanks to their concealed fasteners.

Wind Resistance

The exposed fasteners of the corrugated panels must be tightened regularly so the wind can't work the panels loose. Especially in areas with high winds, the fasteners should be regularly inspected and tightened. ARCO’s Standing seam roofs are not affected by high winds. The side joints of the panels are locked and zipped tightly together without exposed fasteners.

In the conventional roofing system, the short length of panels and the necessity for end-lap connection details, the exposed fasteners and the reaction to the floating of the metal sheet, result in an inability to maintain the system's air and water tightness integrity. With ARCO's standing seam metal roofs, you can be sure of 100% weather resistance.

Appearance and Finishing

Exposed fastened panels use a screw or nail to secure the metal roofing to the purlins. This can involve hundreds and even thousands of fasteners, which must be spaced and driven to maintain the integrity of their rubber washer which serve to prevent precipitation from gaining access through each hole.

Conversely, with ARCO's system where the fasteners are driven through the clips into the roof deck with no connection or piercing of the metal panels. The clip and fasteners are concealed beneath the standing seam panel material. The panel is then laid over and attached to the clips and then mechanically locked.

05

Float Action

Metal expands and contracts with temperature change, with exposed fastener roofs, screws driven too tight leave no room for expansion and contraction.

In contrast, with ARCO's system is driven through the clip and not the panel itself and is designed to flex or move under the panel. And of course, the concealed fasteners are never exposed to the weather and are insulated from the movement.

06

Cost impact

Exposed fastener metal roofing panels are a less expensive alternative to standing seam roofs. However, additional maintenance expenses and the possibility of roof replacement should be considered. It is definitely not an "install it and forget it" type of roofs.

ARCO's Standing seam metal roof will last significantly longer than corrugated metal roofs. It Is the ideal system for low slope roof, which require less structural materials and reduce material costs. It's a smart investment in your Building.

07

Design Potential

Design of conventional roofing systems is very limited comparing to the ARCO's Standing seam system, which allows for unlimited design flexibility to accomodate the market trends in that sector.
