The Formed Roof

The last post showed how the walls were made,
 this time I want to show how the roof is formed up and poured with concrete.

(To see an updated version of this post go to
A Concrete Hip Roof In San Carlos, Sonora.)

This house ( different from the one in the last post ) is next to the church in 
San Carlos, Sonora.

This shows the back of the house and where they left the overhang 
to allow for another room to be added. Note the rebar extending out
 from the section of roof that has already been poured.

The day we walked by they had already taken down the form boards
 for the overhang but inside they were still up.

Termites will go up walls to any wood in the roof or ceiling so everything 
is concrete. Looking up you can see a beautifully formed hip roof. Of course
all the wooden form boards will be removed.

This roof will also be the ceiling, probably plastered and painted.
 On the concrete outside will most likely have clay tiles. Another possibility
could be a latex roof coating. Either will keep the inside cooler 
( especially the tiles ) and prevent the concrete from absorbing moisture.
 Other popular roofs we have seen in Mexico include brick domes
 and vaults and ones supported by concrete rafters.

At the time we spotted the new roof we also took note 
of the wiring they were doing. It looked like nice clean
work. The conduit is plastic.

The wiring diagram was hanging on the wall. I always have my eyes peeled
 for work in progress, so I hope to add to these blogs in the future.
