The phrase "above roof" is not correct and does not convey a clear meaning in written English.
It may be intended to describe something located above a roof, but the phrasing is awkward and unclear.
Example: "The antenna is positioned above the roof of the building."
Alternatives: "on top of the roof" or "over the roof".
This paper presents a numerical study of above roof wind flow characteristics in three suburban landscapes characterized by houses with different roof profiles, namely: pitched roofs, pyramidal roofs and flat roofs.
It is found that the pollutant transport and diffusion is strongly dependent upon the type of flow regime inside the canyon and exchange between canyon and the above roof air.
This data is then combined in the model to predict the distribution and the urban background (above roof) concentration of the modelled air pollutant.
The cable-stayed roof is supported from above by steel cables radiating downward from masts that rise above roof level.
Data from all employed sources give evidence of a flow acceleration (in some cases, rather sharp) above roof level.
A flat roof structure in bending is supported from above by steel cables radiating downward from masts that rise above roof level; spans of up to 72 metres (236 feet) have been built.
The Guggenheim's "Green Violinist" (1923-24), which similarly depicts a violinist hovering above roofs, is also cited as a precursor.
The objective of the present work is to investigate the turbulent airflow in street canyons and in particular, its coupling to the turbulent airflow above roofs.
Wind turbines could rise up to 55 feet above roofs, but only on buildings taller than 100 feet or those near the waterfront, where winds are consistent enough to generate power reliably.
One of the solutions usually assumed is that relay stations (RSs) are placed in specifically planned positions above roof-top or in lampposts, ensuring line-of-sight (LOS) conditions in the BS RS link, and hence reducing the path loss and shadowing effects.
Meanwhile, the inner surface temperatures of the planting roofs were 3.8 °C, 3.7 °C and 2.8 °C lower than that of the above three roofs.
