What is the purpose of a gambrel roof?
The advantage of the gambrel roof design is that it can provide an elegant aesthetic and allows for increased storage or living space beneath its steeper sides. It maximises headroom inside the upper storey of the building whilst lowering, what would if it were simply-pitched, be a very tall roof.
Why is it called gambrel roof?

What are 3 disadvantages of a gambrel roof?
Gambrel roof disadvantages Exhibits poor resistance to snow puddling. The flatter side of the gambrel roof is not made for snow puddling, and it shows. Prone to uneven wear. It is not retrofitting friendly. It is more vulnerable to wind gusts. It requires waterproofing. Some designs have ventilation issues.
What is the difference between a gambrel roof and a mansard roof?
A gambrel, or barn roof, is much like mansard in a sense that it has two different slopes. The difference between the two is that the gambrel only has two sides, while the mansard has four. Similar to mansard, the lower side of the gambrel roof has an almost vertical, steep slope, while the upper slope is much lower.
What are the pros and cons of a gambrel roof?
They typically use two beams with gusset joints for the underlying structure. Because of the easy build, gambrel roofs are cheaper to install and maintain than a more complex roof system. In addition, it takes fewer materials to build a gambrel roof, making it more cost-effective in that way as well.
Are gambrel roofs good?
Gambrel roofs provide excellent drainage. The steeper slope of a gambrel roof provides a structure with an excellent drainage profile during heavy precipitation events. It manages rainfall the best, as the water simply runs off of the side of the building without getting captured.
Why have a Dutch barn roof?

Why are Dutch roofs so steep?
Apparently the reason for these terrifying structures is that most properties in the Netherlands are built on soft sandy soil, requiring massive load-bearing stakes called piles to be driven into the earth to support them. Houses are also usually built in a row, which helps them keep each other upright.
Is gambrel roof good for snow?
Contractors construct gambrel roofs with a rather open design, making them slightly more susceptible to collapse. Similar to mansard roofs, this style is not ideal for areas that receive heavy snow and rainfall, as the extreme pressure of these elements can cause the roof to buckle.
How do you support a gambrel roof?
Also, most gambrel roofs require a kneewall to support the knuckle, or the joint between the upper and lower roof slopes. You have to build the kneewall first, then brace it straight and work around the wall and its braces while installing two sets of rafters.
Is a gambrel roof more expensive?
Danny Looper, a commercial sales manager for Lowe’s, in Cookeville, TN, notes that “a gambrel roof costs between 15 and 20 percent more than a gable roof.” This means that, if it will cost $10,000 to build a gable roof, it will cost between $11,500 and $12,000 to build a gambrel roof for the same building.
What are 3 disadvantages of a mansard roof?
Low Weather Resistance – The Mansard roof is not ideal for resisting extreme weather conditions like areas receiving heavy rainfall or snow. Due to the flatter upper slope, the drainage system of the roof is not good enough. Water or snow can accumulate which can result in dampening or leakages from the roof.
Why do houses have dormers?
Dormers are commonly used to increase the usable space in a loft and to create window openings in a roof plane. A dormer is often one of the primary elements of a loft conversion. As a prominent element of many buildings, different types of dormer have evolved to complement different styles of architecture.
What is the strongest roof style?
