|Use our Oregon Ground Snow Loads map to easily determine the ground snow load (Oregon Building Codes Division) for any location in the State of Oregon. You can click on the map below to find the design ground snow load for that location.
Oregon requires a minimum roof snow load of 20 psf (pm in ASCE 7-10) for all roofs, plus a 5 psf rain-on-snow surcharge for many roof types, resulting in a 25 psf minimum roof design load for most roofs. See the Oregon Snow Load Map Usage Notes for further information and limitations.
Use our Roof Snow Load Calculator to determine your design roof snow loads.
