Gable roof






Gable roof




A form of gable roof (Käsbissendach) on the tower of the church in Hopfen am See, Bavaria


A gable roof[1] is the classic, most commonly occurring roof shape in those parts of the world with cold or temperate climates. It consists of two roof sections sloping in opposite directions and placed such that the highest, horizontal edges meet to form the roof ridge. The design of this type of roof is achieved using rafters, roof trusses or purlins. The pitch of the roof and the height of the gutters can vary greatly.

Distribution


The reason why the gable roof is so common is the simple design of the roof timbers and the rectangular shape of the roof sections. This avoids details which require a great deal of work or cost and which are prone to damage. If the pitch or the rafter lengths of the two roof sections are different, it is described as an 'asymmetrical gable roof'. A gable roof on a church tower (gable tower) is usually called a 'cheese wedge roof' (Käsbissendach) in Switzerland.


Its versatility means that the gable roof is used in many regions of the world. In regions with strong winds and heavy rain, gable roofs are built with a steep pitch in order, for example, to prevent the ingress of water. By comparison, in mountain and alpine regions, gable roofs have a more shallow pitch, because this supports snow better and reduces the risk of an uncontrolled avalanche. Another reason is that due to its high insulation qualities the snow layer acts as insulation against heat loss during winter time and this insulation layer remains atop the shallow roofs longer than on steeper angled roofs.



Advantages and disadvantages


Gable roofs have several advantages:[2]



  • They are inexpensive

  • They may be designed in many different ways.

  • They are based on a simple design principle.[3]

  • They are very weather-resistant


But gable roofs also have some disadvantages:



  • Only roof windows and gable windows may be used for illumination.

  • Low-pitch gable roofs result in a loss of living space. This may be partly compensated for e.g. by the installation of dormers.



Types and categorisation


Gable roofs may be constructed with different pitches and these are sometimes categorised by different names. For example in German-speaking countries the types of gable roof are:



  • Shallow gable roof (flaches Satteldach) with a pitch of ≤ 30°

  • New German (neudeutsches Dach) or angled roof (Winkeldach) with a pitch of 45°

  • When the pitch it greater than 62° it is called a Gothic (gotisches) or Old German roof (altdeutsches Dach)

  • If the roof has the shape of an equilateral triangle and 60° pitch it is called an Old Franconian (altfränkisches) (commonly found in the region of Franconia) or Old French roof (altfranzösisches Dach)[4]

Understanding the information contained in the Deep Space Network XML data?

up vote 1 down vote favorite NASA's Deep Space Network activity can be viewed conveniently at https://eyes.nasa.gov/dsn/dsn.html but if you would like data in a more raw XML form, it can be accessed as described in this answer Below is a small Python script that reads the XML into a list of dictionaries, and saves it to disk as a JSON. The dictionaries are organized at the higher level by dish, then by spacecraft per dish.
