Next, the roofing materials are to be chosen and installed.Īdding accessories to the roof can help improve its appearance and function. Once the design has been decided upon, the framing must be calculated. The first step is to decide on the design to be used. Curved Roof DesignĪ curved roof is designed in several steps. The steeper pitch makes it easier for water to run off and reduces damage due to ice buildup. The pitch or slant of the roof also helps to reduce the effects of weather and time on the structure. The slope of the roof should vary by less than 2 inches per 8 feet to prevent the roof from sagging. This area must be supported by a skeletal frame. This slope can be achieved by building a domed area from the center of the roof. The weight of snow and water must be offset by a slight upward slope in the center of the roof. This will prevent the roof from sagging when the weight of water or snow is added. The curve radius should be at least twice the span. The design of a curved roof is aesthetically pleasing, and the curvature of the roof means the roofing materials can be installed from the ground up, without the need for ladders or scaffolding.Ī curved roof is designed with a curve radius that is greater than the span between support columns. Curved roofs are more common in residential-scale buildings than in commercial-scale buildings.
