When building a structure it is important to calculate wind load to ensure that the structure can withstand high winds especially if the building is located in an area known for inclement weather.
Free roof asce.
In order for a structure to be sound and secure the foundation roof and walls must be strong and wind resistant.
Adding to skyciv s already list of free tools is the new wind load calculator for asce 7 10 as 1170 2 and en 1991 ec1 this easy to use calculator will display the wind speed by location via a wind speed map as prescribed by the above building codes.
And with the latest version of asce 7 minimum design loads for buildings and other structures asce 7 it has become that much more challenging for roof system designers and roofing contractors.

Roofs of buildings with mean roof height 60 feet asce 7 16 section 30 3 roof component and cladding loads for buildings with mean roof heights of 60 feet or less have been revised significantly from asce 7 10.
Asce 7 10 and asce 7 16 recognize that structural members deflect and sufficient member stiffness is necessary to promote free drainage of a 1 4 in 12 design slope.
Whereas asce 7 10 contained 4 pressure coefficient gc p graphs for roof slopes of 0 to 45 asce 7 16 includes 9 new figures.

Figure asce 7 95 monoslope roofs refer to notes on figure.
I noticed that asce 7 10 figure 30 8 1 has a note which states that cn is net pressure with contributions from the top and bottom surfaces.
Additionally asce 7 16 requires a minimum 1 in 12 roof slope to promote free drainage for secondary members parallel to a free drainage edge.
