Bell Roof Design and Construction Guide

A bell roof is a classic design that adds a touch of elegance to any building. The distinctive curved shape of a bell roof is created by the use of a series of arches that meet at a central point.

To achieve this unique shape, a bell roof typically consists of two slopes that meet at a sharp angle, creating a narrow ridge. This design allows for a wider overhang, which can provide additional protection from the elements.

The materials used to construct a bell roof can vary, but a combination of wood and metal is often used for its durability and aesthetic appeal. The roof's structure is usually supported by a series of beams and rafters that are carefully spaced to maintain the roof's curvature.

The bell roof's unique shape requires a specific framing and construction approach.

A bell roof's curved shape is typically achieved with a combination of rafters and a center ridge beam.

The rafters are usually sloped at an angle of around 20-30 degrees to create the bell shape.

In some cases, a curved rafter system is used to create a more precise and uniform curve.

The center ridge beam is usually a solid piece of wood that runs along the top of the roof, providing additional support and stability.

A bell roof's construction requires a deep overhang to protect the walls from rain and weather.

The overhang can be achieved by extending the rafters beyond the exterior walls, creating a sloping roof edge.

A minimum overhang of 12-18 inches is recommended to ensure adequate protection.

The decorative bell roof chimney cap is a beautiful and functional addition to any home. It features a decorative roof with clean lines that curve both ways for a flowing look.

This type of chimney cap is easy to clean thanks to a removable square or rectangular cover at the top. The cover can be taken off for easy access.

The bell roof multi flue chimney cap can be mounted either on the side or on top of the chimney. This flexibility is a big plus for homeowners.

Copper or aluminum screen is used to provide ventilation, allowing for airflow while keeping debris out. This is a clever design feature that helps keep the chimney functioning properly.

The minimum size for this type of chimney cap is 30 inches wide and 30 inches long to ensure easy roof cleaning access. However, it can be ordered at a minimum of 26 inches in either dimension, but it won't be accessible for cleaning.

Vertical supports are added to the screen area as needed to ensure stability and strength.
