[Cob] RE: 'temp roof comment'

[Marlin]

I should have been more clear, sorry.

agree that the temp roof structure should be sound,,,,also what sound means depends on your locale. Here (Wisconsin) we'd need tie downs for tornadic-type weather but not probably plan for earthquakes.....I always like a lot of bracing too (can drive people nuts but it def. makes it stronger to triangulate)

BUT, what the temp roof does is gets it out of the way of the wall building, puts a lot of potentially bad building dayz (sometimes weeks here) back into work days under your roof and makes a readymade porch all in one swoop. By the end of a lot of building projects the roof is often a big annoyance and this way it's built first. Wonder if it would promote better planning right from the start of a project ?("yahoo, let's go start throwing Cob down and figure out a roof plan later....";-)

AsShannon pointed out, it could therefore stand as a 'gazebo' if the building was never even built (store people, materials etc. out of the rain, sun etc. too)

So, in summary, the "temp" was the fact that the final support (and additional tie downs into the cob wall) would come from the wall built later.

Perhaps I am over reacting to your above statement, but even if my
interpretation is not what you meant, I think the following is
important for people to realize.

One of my concerns about the "temp" roof concept is that people will go
with a less than sound temporary structure to support the roof while they
are putting up the building because "it's only temporary".  Frankly, the
only time you need the roof while building is during bad weather, the
exact conditions which stress the roof and its support framework the most
(aside from the potential siesmic events), making these "temporary"
designs exceedingly dangerous.  Personally, if I were to go this route,
even though it was temporary, I would mount it as though the roof needed
to stand there alone for decades, anything less is potentially suicidal.
