Which of the following is NOT a style of roof construction commonly found on typical taxpayers?

Gable roofs are characterized by their peaked shape, where two sloping sides come together at a ridge. This style is commonly seen in residential buildings and traditional homes rather than in taxpayer buildings, which often feature more practical and commercial designs. Taxpayer buildings typically require roofs that are simpler and more utilitarian, leading to the prevalence of other types such as flat, bowstring, and inverted flat roofs.

Inverted flat roofs are designed with a slight slope to allow for drainage, while standard flat roofs provide a uniform surface that is often less expensive to construct and maintain. Bowstring roofs, with their arched design, offer open space beneath and are used in larger commercial structures. These features cater to the functional needs of taxpayer buildings, making gable roofs less suitable for this type of construction.
