Wind Loads on Roof Affecting Antenna

[reslife]

Hello all,

I am mounting an antenna on a roof of a building, and I am trying to figure out the wind loads it will experience. Once I have these loads I can calculate the stresses on the bolts it is mounted on. Here is my question:

How will the angle of the roof (14 degrees) affect the wind load? I had planned to use 130 mph for the wind load, but I'd like to know how much the wind speed coming over the top of the roof will change.

Any help is appreciated!

How much would just being conservative and assuming a 130 mph horizontal wind affect your result?
