Choosing Materials for Curved RoofsĪ suitable material for a curved roof depends on your project. This complex curvature type combines convex and concave curves. You should note that since domes and gothic arches require the underlying structure to be built up, they can be a challenge to construct unless you hire a professional contractor for the job. The Arch-shaped roof has an arch form usually where the arches are round, pointed or polygonal. Segmental arches may be circular, elliptical or polygonal. Semi-circular curved roofs usually have their arcs concentrically located on an entirely circular or elliptical plan. Side Arched Roofs have two different types, semi-circular and segmental arches. Vaulted Roofsīarrel Vaulted Roofs have an arch like shape with a semicircular cross section that curves upward at either end while dome shaped roofs curve inward from all directions except one side (usually where it joins a wall) and a gothic style vaulted roof is similar to barrel vaulted roofing except that the top of the arch is pointed instead of semicircular. The most common types of curved roofs are barrel vaults, domes and gothic style arches. There are many benefits to curved roofing such as lower cooling costs because of their natural shading abilities, better air quality due to less heat retention, and wind resistance which protects against storm damage. Curved roof designs can be used to create beautiful landscapes that not only look good, but they also provide protection for the people who live in the home or work in the building. Benefits of Curved RoofsĬurved roofs are a design that is becoming more and more popular. However, it can prove to be very beneficial. The roof design specialist must have experience with curved roofs and will be able to show you the possibilities.Ī curved roof design is a more expensive roof type than other types of roofs. The best way to find a qualified contractor is to contact firsthand recommendations. Using the wrong materials can lead to serious structural damage and expensive repair costs. It is important to hire a professional to ensure that the design is built correctly. This section explains some choices for these accessories, including skylights, vents, and lightning protection systems that are available for curved roofs.Ĭurved roofs are more complex than flat roofs. 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.
