Gambrel roofs, also known as barn roofs, are a popular roofing style that features a unique two-sided slope. This type of roof is often seen in barns, but can also be found on homes and other structures. Some synonyms for gambrel roofs include barn roofs, Dutch roofs, and mansard roofs. Dutch roofs are similar to gambrel roofs, but have a more gradual slope. Mansard roofs, on the other hand, have a steeper slope on the lower portion of the roof and a flatter slope on the upper portion. Other terms that may be used to describe gambrel roofs include horsehead roofs, curb roofs, and curb-gabled roofs.
