Low Slope Copper Roof

An average sized copper roof will cost between 30 000 to 60 000 or even more to install.

Low slope copper roof.

These are soldered interlocking systems of metal panels. For roof slopes less than 6 on 12 the upper roof pan is attached to a locking strip soldered to the lower pan. Today it is rather rare that an entire roof gets covered with copper. Low slope metal roofs require less material which reduces the overall load on the building s structure.

First the metal must be cut down to pans no larger than 18 by 24 inches so thermal expansion and contraction won t overstress the solder joints. Traditionally low slope or flat roofs would use a built up tar and gravel roof but today this traditional type of roofing suffers from performance cost environmental concerns requiring better value solutions. For a long span roof utilizing multiple seamed pan lengths transverse seams are required. The minimum roof slope for metal roof panels depend on 3 different scenarios.

They are also used on curved surfaces such as domes and barrel vaults. Instead only sections such as towers porches bay windows and low slope sections copper with soldered seams get copper for looks or waterproofing purposes. Copper and stainless steel can be used for low slope roofs but a fair amount of planning is involved. Flat seam roofing systems are typically used on roofs that are flat or have a low pitch or alternatively on very steep slopes.

See example table 8 8a. Rectangular cold rolled copper sheets. Flat seam roofing is constructed of 18 by 24 20 oz. Low slope metal panel roofing may be a standing seam roof ssr through fastened roof tfr or insulated metal panel imp roof.

These panels generally come with a painted mill finish or a clear acrylic finish. An ssr has side joints between the roof panels that are arranged in a vertical position above the roof line. Lapped nonsoldered seam metal roofs without applied lap sealant must have a minimum roof slope of 3 12 25 slope. Low slope roofs are not totally flat their roof slope generally ranges from 1 4 12 to 3 12.

A more expensive low slope or flat roof option include sealed metal roofs using copper or tin. This means for every 12 horizontal units the roof must rise a minimum of 3 vertical units.
