Also different architectural styles will use the same type of roof.

Compare massings layout and envelope options. Valleys can allow water to pool. In some ways it is similar in style to the mansard roof discussed above because it has two varying slopes. Intricate roofs have many parts that incorporate several of the basic roof designs such as a gable roof sitting atop a gambrel or variations of the gable valley roof design using one or a variety of different types of roof trusses also see our very detailed diagrams showing the different parts of a roof truss.

Proper waterproofing is a must. The u value unit is w m2 k. Similar to a cross gable roof. The lower plane has a steeper slope than the upper.

It has a polygon on two sides and a triangle on two sides. The u value characterizes the amount of energy that can be transferred by a material. However a gambrel roof only has 2 sides while a mansard roof has 4 sides. The sides come together at the top to form a simple ridge.

Energy use intensity or eui is a building s annual energy use per unit area. The most common type of a hip roof. Pick the right strategies. Sheathing blocking is added along the valley and the sheathing pieced in for both roof planes.

A gambrel roof usually contains a gable at each end just like a standard gable roof. Here s how to think about the two different slopes. Study natural ventilation hvac systems for all project types. To transition the eaves the horizontal fascia extends to the last rafter tail and a vertical return finishes the transition.

The lower plane has a much steeper pitch than the upper often approaching vertical. The monthly consumption chart in particular tells us what we d like to know. Eui is useful for comparing the performance of buildings across sizes types and locations. A type of roof containing two sloping planes of different pitch on each of four sides.

Two main types of roofs are flat roofs and sloping ones. The lower side of the roof will have a steep slope almost vertical while the upper side of the roof will. The flat roof see the figure has historically been widely used in the middle east the american southwest and anywhere else where the climate is arid and the drainage of water off the roof is thus of secondary importance. The line where the two roofs meet is called a valley.

It is typically measured in thousands of btu per square foot per year kbtu ft2 yr or kwh m2 yr. A type of roof containing two sloping planes of different pitch on each side of the ridge. Charts within the sefaira app offer insights into several different values such as monthly peak cooling and heating demands water use etc. Use separate hip roofs on homes with different wings.
