Western Red Cedar, Cypress, and Douglas Fir are three of the primary exterior softwood options we quote from Black Mountain. They are not interchangeable: Cedar and Cypress usually lead for siding, porch ceilings, soffits, and trim, while Douglas Fir leads for timbers, beams, and posts — and can still cover boards when fir is preferred.
