Porch conversion to insulated space
What would be the best option for insulating this ceiling? It is just beams and 2x6 T&G with shingles on top. Structural engineer doesn't want us to redo the roof to add Zip R-3 on top of the existing 2x6 T&G because of the increased dead load. (The beams are of unknown specifications.) Any other options for roofing solutions? We like the look of the 2x6 T&G from below so I'd prefer to redo the roof somehow...
Thanks ya'll! I really appreciate all the advice!
