OLD WOOD BUILDING IN NJ
OLD WOOD BUILDING IN NJ
(OP)
We are performing remodeling work for a one-floor wooden building in New Jersey, US built in 1957.
One of the tasks is to evaluate the existing roof capacity for possible additional loading.
The existing roof is 2x10 rafters at 16" OC across two spans of 17' and 15'. The roof has an 11/16 to 12 slope.
We believe the existing roof may be designed to resist 35 PSF ground snow.
Our challenge is identify the species and grade of existing wooden rafters.
Can anyone give me an educated guess for the most possible species and grade of the existing rafters?
We might use the lowest design values in the code but it would be nicer we can get a little bit higher value and save some money for our client.
Thank you for your help.

I trust this is a response to the specific question asked by the OP and not your general design philosophy.
