As its name suggests, a bell roof is a roof resembling the shape of a bell.  This roofing type often comes in different forms, such as round, square, and multi-sided.  Because of its classic appearance, a bell roof is typically found on various vintage-looking structures, including Colonial-era churches and schools, as well as historical homes such as Tudor, Victorian, Queen Anne, and Edwardian homes.  Bell roofs can be used along with similar-sounding features like bell-cast, sprocket, or flared eaves, highlighting the roof flairs and making them look more like the bottom of a bell.



Additional labor costs are encountered on bell-shaped roofs regardless of what type of roofing is installed.  Bell-shaped roofs differ from gambrel-style roofs in that the pitch change is a curved radius rather than an abrupt change.



If metal roofs can be used on bell-shaped roofs, it avoids the cost of future re-roofing.  Whether a particular metal profile can be used depends upon the product and also upon how “tight” the curve is.  Generally, larger curves are easier to accommodate.  Most vertically seamed panels are not intended for bell-shaped roofs.  Some standing seam profiles, however, can be pre-curved by the manufacturer or by an outside source.  In other cases, hand-forming of panels on the jobsite by a sheet metal expert can allow for curving.  Many horizontally run metal shingles can be used on curved roofs, including Classic Products’ steel and aluminum shakes.  In some cases, particularly with very tight curves, it might be necessary to shorten the shingle courses so that they are not spanning over too much of the curve.

Using shingles with a great vertical exposure or with wood batten systems beneath them can reduce the visibility of the curve.  Walking directly on the curved part of the roof should be avoided as there will be more airspace beneath the panels than normal.  Classic Products Slate panels, though they have a high exposure, can be pre-curved at the factory to meet most roof curves.  Whenever a manufacturer is pre-curving the panels, they should be supplied with a wood or cardboard template of the exact curve that they can follow.
