Question by Don: How heavy does a roof need built to support a 185# / per square foot load?
Will 2″ x 8″ tongue and groove sheathing over log rafters spaced 4′ apart support this much weight? I’m interested in building a house with straw bales for roof insulation and 6″ of living turf on top (over a rubber membrane). Any structural engineers or knowledgeable carpenters out there? Thanks!
Best answer:
Answer by oil field trash
What is the span and the diameter of the logs? What kind of logs are they? What is the density of the straw bales?
With out this kind of info, know one can really answer your question.
My guess is the logs are spaced too far apart by a factor of two or three.
