With the high cost of labor and materials, a new roofing system has become a major investment for homeowners. Many traditional roof types, including slate and clay tile, that have been popular for centuries are now out of reach for most residents. Fortunately, more affordable materials that offer significant benefits are available. Metal roofing is an increasingly popular option that has replaced some of the more conventional systems. Steel, aluminum and even copper in the form of either sheets, shingles, tile or roofing pans now appear on housetops of every architectural style. A standing seam roof is particularly sturdy, regardless of whether the roofing pans are short or long. Each pan measures between 18 and 24 inches wide and is laid parallel to the roof's slope. Morris County roofers can provide more information about these versatile systems to clients seeking a durable roof structure for a reasonable price.

If the pans are made of copper, then they can be formed on the job site with special equipment. They may be rafter length and require no transverse seams on the ends. Adjacent pans are generally secured together with double locked standing seams. To adhere them to the decking, technicians use fixed copper cleats placed a foot apart. These tightly locked cleats occasionally lose their sheathing fasteners after the long pans have expanded and contracted many times. Because expansion cleats rather than fixed ones can be utilized for pans that are longer than ten feet, roofers can minimize the damage caused by the metal's cyclic movement.

The roofing experts from Peter W Smith Construction of Morris County NJ would be happy to answer any questions you have about roof replacement or roof repair.

Expansion cleats also help to prevent "oil canning."

Roof pans should never exceed 45 feet in length. The structural strength is compromised at that size because the metal loses its ability to transfer expansion stresses to a designated release point. Sometimes these points are loose locked seams that let adjacent pans expand and contract relative to one another. Other common spots for stress relief are the eaves, ridge and transverse joints. As long as the copper has fasteners that do not interfere with thermal movement along with the appropriate clearances, long pans will continue to serve as strong, durable roofing components.

Installation requirements are different for long pans than for those shorter than 10 feet. Proper alignment is critical, and the expansion cleats must be placed at the correct locations. All seams have to be designed to accommodate the necessary stress relief. Even the building's characteristics must be considered before the sheets are laid. When the framework faces the south, its roofing system gains a lot of heat and affects the pan seams. Expansion joints are also an area of concern and must be installed with care. Roof penetrations like chimneys and vents also need room for expansion.
