Renovation, roof repair and theft prevention

It is now a norm that owner of new houses install security alarm system to protect their house from theft.

There are many types of security alarm system available in the market and they mainly consist of magnetic contact and vibration sensors to be installed at doors or windows to detect any intrusion. There are also infra red sensor to detect any movement within any particular space such as living room etc.

While the magnetic contact or vibration sensors will trigger the alarm whenever there is an intruder entering through the door or window. Infra red sensor will detect movement but that include the movement of pet or rat.

Some intruder may choose to enter the house through the roof by removing the roof tiles. The infra red sensors can be used for the space below the roof tiles within the roof truss area above the ceiling but that will cause a lot of inconvenience to the occupant of the house as alarm will be triggered when ever there rats moving above the ceiling area. So most owner will compromise safety for the sake of convenience.

But if you are renovating your house and if your renovation works include the replacement of roof tiles, then you can take the opportunity to install a layer of galvanised iron steel sheet or plywood immediately below the roof tiles location to completely cover the roof area before the roof tiles are being relaid on the galvanised sheet or plywood. The steel sheet or plywood will prevent easy entry of thief as any cutting of those material will create noise and takes time which the thief surely do not want.

Moreover if you choose to use galvanised iron steel sheet to cover the roof below the roof tiles, the roof will be almost completely leak proof thus serving two purposes of theft prevention and leak prevention.
