I want to install grills on the roof to prevent thieves coming in the house from the roof. My house's roof is high is steep.

Do you guys know what kind of "grill" I can put up and roughly how much? Any good company to recommend?

Somebody told me that I can install the metal furring or metal furring with zinc plate. Are those good?

err..bro..my contractor told me about it...i said go ahead smile.gif

Cos he did my friend's house...and it really helps to prevent robbers from coming in from roof and reduces temperature...basically it is sealing off your roof tiles from the roof trust...even can assist to prevent roof leakages..

that's all info i have smile.gif

probably cost around 4-5k ...well he bundled into my wetworks...

and yes, will have to remove the roof tiles to lay the thingy...can be done anytime during reno or after reno
ask the contractors..they will know

Additional info : my fren realised there was water thru from the roof...and then got the contractor to look at it again, and the contractor found out that tiles were removed...and then when they tracked back..they remembered that prior to that happening..one of the neighbours house got broken into via the roof.

and my fren's house was not broken into..I assume they tried thru the roof but with the "zync" they could not get in...

Note that eventhough zinc sheets may be a good idea, it may well invalidate your home fire insurance. You may want to check on this first.

Some contractor give good idea too, instead of Zinc, they put BRC on the wood truss.

I was quote using this method when sourcing for contractor during my house rebuild last year.

You can use the chicken coop type wire mesh and place below the roof tiles. It's does not stop ppl from coming in if they really want to but it does work as a pretty good deterrent.

That one too thin, the BRC is actually very good idea. But the wood truss need to have enough support.

If you decide go for Zink, nake sure the workmanship is good and the ending should phasing out instead of inside. Else if you have water leak issue than very difficult to trace back.

Maybe want to included alumnimun fold to reduce heat too

I am using Zinc, so far heat reduction is good, usually by 12 to 1pm, first floor will be hot, but with zinc, you only feel hot around 3+pm.

That is first time I heard terrace link house no brick block between above the ceiling. All I see have a brick wall between.

I think this is cost cutting extreme.

BRC isn't a good idea. Hardly renovators will use this. BRC rust when it comes in contact with moisture. And above the ceiling, there will be plenty due to heat and rain in Malaysia.

Normally, the other method would be to install additional 2"x2" timber batters assuming yours is made of timber roof truss. If it uses metal truss, then your battens will be made of Zincalume material. It basically adds on in between the existing batter, which means narrowing the gap that a human cannot go through just by lifting up the roof tiles.

And if you renovators do not know what battens are, then I am speechless.

Most new houses do come with a party wall above the roof beam. It is a requirement from BOMBA in which the thickness is dependent on the brick type. Clay bricks only requires 4 1/2 inch thick which requires a layer of plaster while cement sang brick requires 9 inch thick. These walls needs to be a minimum 230mm higher than the roof level of the house.

QUOTE(noien @ Feb 23 2012, 10:10 AM)

They do. Older houses maybe. If there isn't, most likely it is a cost cutting exercise which you can report to BOMBA if you want to.
