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. erika ********************* Ohio License # 44844 NABCEP Certified Solar PV Installer R Certified Home Energy Rater REpower SOLUTIONS Visit online: www.repowersolutions.com Renewable energy and home energy audits P.O.

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 _______________________________________________ List sponsored by Home Power magazine List Address: [email protected] Options & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org _______________________________________________ List sponsored by Home Power magazine List Address: [email protected] Options & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org
