Bann Nah 12 - Lan Kha

With the teak structural posts installed on the second main floor beams, along with some wood cross supports and temporary eucalyptus scaffolding, the rafters went in so that the roof (lan kah) could be screwed on.

One note about the second story posts: these are attached to the main floor beams in much the same way as the concrete posts are. Both concrete and wood posts are notched and fit inside the main floor beams that are grouped in pairs, so that the notch fits inside the floor beams. In the case of the concrete posts, the floor beams rest on them and are bolted to them. In the case of the wood posts, they rest on the floor beams and are also bolted to them.

 Within the past 70 years, roofs for homes in the Thai countryside have gone from thatch to corrugated tin and now to “aluminium” (aka “aluminum”) and concrete tile (“C Pac”).

We decided to go with corrugated metal, like we did with our first story roof at our village home, not only for the lighter weight, but also for the price and durability – choosing a thicker grade rather than the thinner.

Also, we opted not to go with color. It is my opinion that the enamel process in Thailand is not standard and that the painting process for concrete tile is not uniform, either. Looking at both color-enameled aluminum roofs and colored concrete tile roofs of more than ten years, I see various shades of tiles and roof sections. The Thai sun is, no doubt, merciless. I want a roof to continue to look good beyond ten years, even if it develops its own weather-beaten shade of duller silver.
