Grade of existing lumber unknown.
Grade of existing lumber unknown.
(OP)
I am analyzing an existing roof for potential additional snow loads. The building roof structure is timber joists and girders. The building is very old and there are no grading stamps to be found. The lumber appears to be rough sawn spruce and from what I understand, local spruce was likely used. Does anyone have a suggestion for what grade to use. I did see an earlier thread where it was considered conservative to use S-P-F #1/#2 and that is what I was leaning towards using. Does anyone have any other suggestions?
Thanks
Thanks

Here in Florida i would feel a little uncomfortable assuming Southern Pine #2, which is the most common here, and what properties and material I spec out in my designs.
