I have been able to work with a P.E. or architect to the tune of about
$250-350 (maybe $1000 if they are very uncomfortable with the situation) to
come inspect the roof (or take my very detailed description of the
construction details)so that they can create a letter that says the roof can
take additional weight of X with Y attachments per square foot with a total
surface area of Z.
In some cases we have added support per suggestions for extra overkill
measures, making everyone feel better. Then nobody ever goes up into the
attic again.
Good luck.

Subject: [RE-wrenches] truss loading
Hi All,
We were recently notified by our local building department that all
future building permits will require a letter from a state licensed
engineer stating the existing roof trusses are adequate for the
additional load a solar system will add. All roofs in our area have
a 30 pound per square foot snow load requirement. The building
departments concern is truss manufactures design the trusses to very
tight tolerances and there is no room for additional load. Has
anyone had to address similar requirements? Any ideas on how to
approach this issue would be appreciated.
Thanks in advance, Rip
