I believe you are referring to an area of the roof called a valley. A valley is formed anywhere the downward slope of two roof surfaces meet.
From AS 1684.4 Residential Timber Framing Code 2.6.4.1 Coupled roof Pitched roof construction with a roof slope not less than 10°, with ceiling joists and collar ties fixed to opposing common rafter pairs and a ridgeboard at the apex of the roof (see Figure 7.1). A coupled roof system may include some area where it is not possible to fix ceiling joists or collar ties to all rafters, e.g., hip ends or parts of T- or L-shaped house. 2.6.4.2 Non-coupled roof A pitched roof that is not a coupled roof and includes cathedral roofs and roofs constructed using ridge and intermediate beams.
a gable roof is double pitched with vertical ends
The minimum covering of reinforcement for roof slab is 30mm
Roofs may be functionally flat or "pitched". In building construction, roof pitch is a numerical measure of the steepness of a roof. A flat roof on the otherhand, is a roof which is almost level in contrast to the many types of sloped roofs. The slope of a roof is properly known as its pitch and flat roofs have up to approximately 10°. If you have a flat roof, there is probably a leak in it or there will be a need for a flat roof repairs in the future.
On top of your roof, away from trees, in an open area.
there is no roof on them to open
The area of a roof can be determined from the area covered by the building to the outside of the walls and taking in to account the pitch of the roof by adding on a percentage depending on the pitch. A method is shown at the web link below along with a table of the percentages to be allowed.
Another dimension is needed to work out the surface area of the roof.
The highest point of each roof area.

a sunroof is a glass panel on the roof that when you open it air will come through the roof in also has a protecter that you open use the sunroof
The wind travels over the roof creating an area of low-pressure directly above the roof. When the pressure below the roof increases to a point that is greater than the pressure above plus greater than the buildings' structural resistance off it goes.
Unless you have a flat roof, no; the surface area of the roof will be larger than the ground area of the building.
I think Veranda is not open to the sky (roof Topped) where as balcony is open to the sky (no roof Topped). Thank you
Opening a sun roof on a jeep is easy. All you have to do is unlatch the roof from the jeep and push the open button.
