The pitch of a roof is its vertical 'rise' over its horizontal 'run’ (i.e. its span), also known as its 'slope'. In the imperial measurement systems, "pitch" is usually expressed with the rise first and run second (in the US, run is held to number 12; [1] e.g., 3:12, 4:12, 5:12). In metric systems either the angle in degrees or rise per unit ...
In 2008, EagleView introduced an aerial roof measurement technology [8] using algorithms to infer the size and area of the roof. [9]In 2011, EagleView introduced EagleView SunSite, a solar 3D-roofing report for solar integrators and installers that estimates solar exposure, rafter lengths, grid layout and overall roof orientation in degrees.
Domestic roof construction is the framing and roof covering which is found on most detached houses in cold and temperate climates. [1] Such roofs are built with mostly timber, take a number of different shapes, and are covered with a variety of materials.
The building has a roof height of 1,250 feet (380 m) and stands a total of 1,454 feet (443.2 m) tall, including its antenna. The Empire State Building was the world's tallest building until the first tower of the World Trade Center was topped out in 1970 ; following the September 11 attacks in 2001, the Empire State Building was New York City's ...
A flat roof is the most cost-efficient roof shape as all room space can be used fully (below and above the roof). Having a smaller surface area, flat roofs require less material and are usually stronger than pitched roofs. [26] This style roof also provides ample space for solar panels or outdoor recreational use such as roof gardens.

Construction in Australia no longer uses the square as a unit of measure, and it has been replaced by the square metre. The measurement was often used by estate agents to make the building sound larger as the measure includes the areas outside under the eaves, and so cannot be directly compared to the internal floor area.
