The Roof

Share

There is nothing wrong with the roof.

When we got in initially, one of the main concern is the quality of the roof structure itself, and the possibility of Termites infestation.

After investigation by the Pesticide company, I am glad to know that, after almost 30 years of standing, the wood structure in the house remained firmly intact, with no evidence of termite infiltration whatsoever.

Despite all that, due to the extension of the house, the roof will need to be rebuild, so that the extension too will have a good drainage from the rain.

Here's the old roofing:

The old extension has insufficient slope angle for proper drainage.

The new roof, shown in the yellow segment, will be about 4-5 ft taller to cater for the extension.

The new roof will also house two water tank, side by side, for domestic consumption.

There are two kind of structural supports available, Wooden support beam or metal support.


Metal support would be generally lighter, less defects, and with no danger of future termites infestation.  But it is also more expensive.

Wood however is cheaper, though by not much.  In our case, we can still harness the old structure as the hard wood is still in very very good condition.  It will be a waste if we were to just throw them away as nowadays the price of solid hard wood can be comparable to metal.

So after using back the old wood, we only need to get a little more to rebuild the whole roof. That translates into cost saving.  We decided to opt for wood as a result.

These are the old hard wood used for almost 30+ years.  Its still in very good condition despite its age. They are now stored for rebuilding purposes.

The new brick can be seen elevated the roof by about a metre plus.

Zinc plates arrived.  It will form the base layer before laying down the roof tiles.  It does prevent leakages, intrusions and, to a certain extent, heat from sieving through.

Here it is.  The zinc plate are being laid.

The almost final look.  Overall it is about 4 ft higher than the original roof.  Hopefully it can also cool down the house a little.

It will be followed by the final act of placing ventilation shield to allow air movement in and out of the roof for cooling effect.

Stay tuned.

First stage of wiring is being made before the ceiling board.

This is how the Air Vent looked like.  It allows cooler air to flow in, and allow the hotter roof space air to leak out through the side vents. This is very much an experimental shot, hopefully it can effectively reduce the temperature of the underlying rooms.

***************

One side of the roofing support appear to have a small sinking appearance.  Although it is of no harm.  My wife suggest rectification at this point. 

 

This is after the rectification job.
