The greatest structural burden on the house comes from the roof. A heavy roof will cause the house to shift and settle, causing cracks and structural misalignment. These effects may be evident as early as three to five years after installation. All national building codes dictate that if the weight of the roofing material exceeds six pounds per square foot then the residence will require additional structural support. This will often incur additional expenses for structural analysis, materials, and installation. Additionally, older homes that require re-roofing are often in need of structural reinforcement when using concrete, clay tile, or fiber-cement.
Weighing at average of 1.4 pounds per square foot, a Roser roof is an ideal solution for homes or commercial projects that cannot be structurally altered, or when structural changes would incur significant costs. A Roser Stone Coated Steel Roof was not only designed to decrease structural load on a residence. It also improves the structural integrity of the house through an interlocking fastener system, providing significant reinforcement during physical stresses such as hurricanes, earthquakes, and hail storms.
Homeowners and installers often choose Roser for applications for where they want the look of tile or shake, but cannot go with concrete or cement due to weight restrictions. Additionally, Roser Tile, Shake and Shingle profiles are offered in a greater variety of colors then concrete, cement or asphalt roofs.
