ASCE 7 Wind Pressure

I’m looking for information on calculating wind pressures on a low-rise building with two levels of sloping roofs. Example, a 30-foot high main building with a 15-ft high attached office area along one or both sides. ASCE 7 addresses this situation with flat roofs, but not sloping roofs. Any suggestions would be appreciated.
