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?

Bro..actually no need grills..U can lay a layer of "zinc" ....cant remember wats the term....

this "zinc" reduces heat and also....can prevent robbers from coming in...
hope it helps....yea i heard its good...I m installing it during my reno next month

but the "zinc" can be installed after everything is completed or only during renovation?

eh bro, any additional info regarding the zinc u mentioned?

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

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

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.

Yea my fren told me the same experience...hence I decided to do it....

zinc?
i thought it was double aluminium foil with fiber glass sandwich in between..
i come rolled and u spread it on top of your truss before cover it up with roof tiles...



like that but thinner..

but if u r leaving in a terrace house, the entire roof are link together.so i don think it is possible to reduce theft

Link, but block with bricks.

Now I know some don't. Remeber last month back where whole family murder in sibu. The guy climb up to the ceiling from his house and cross over few house to steal. Apparently the link don't have brick to block.

Maybe old house.

normally it is linked together

even new house also don have bricks to block

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.

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.

Somehow, I feel adding Zinc sheets makes troubleshooting a leak harder. As you know, where you see the water may not be the location it leaks from. Adding any sheets for that matter, whether Zinc sheet or Sisalation makes it so hard to find the leakage.

How much are the rust proof Steel Mesh per square meter/foot roughly? Good for me to know as well ...

Varies depends on gauge(thickness) and spacing lah. Check with hardware shop.

You are right about problem to trace leakage.

my contractor told me adding zinc sheet will definately void your house insurance. Instead, they recommed adding horitonzal kayu masak truss small enough gap ppl cannot get thru. At least if fire bomba wafer still can get thru from the roof.Quoted ~7k for the whole job , mine is a dst house.

So all apartment, and concrete roof design will have no fire insurance?

No, that is in correct

7K??? The will take out your roof and play the wood in between only or other thing included of your 7K? Else guess you alredya been con.

So what are the best way now? Currently my house almost get break through from the roof and now looking for better security ways. As read above there are ways like installing Zinc or even grill?

Which is is better and how much does it cost?

Best is if you cast a concrete slab over your roof, then nothing can come in!

is urs single or double storey ?

double storey

wood plus motion sensor...

Myself is Zink + Wood + heat aluminim + Motion Sensor....
Problem statement: Maybe issue to rectifier leaking

Wood is mean to add additional wood to minimize the hole so that no one can drop in? Roughly how much it cost?
How much it cost for your Zink + wood? I already install motion sensor.
TQ~

Another method is put BRC, but roof need additional support. BRC is very heavy for thicck brc.

anyone install grill type b4?

They came in through the roof? Man all these while i never tot they would really go so high up to go in via the roof man...

Material around 1.5K+ (Zink + Wood) , Labour is around 2K (Indo)

Thats good value , they quote me all in 7k , take out roof and place the wood + labour cost

Make sure not curi ayam which done from inside instead of outside. But 7K still expensive, check what if you buy wood and they supply labour , than you will know lol....

But 7K, guess you could almost get a Pro who do those heat rejection as well ...

Why not put the type like aluminium foil with a wool in it and the chicken fence? You can cool down your house and prevent roof hack in together.

2 in 1. Instead just a roof security.

7k?!!!! how about put a 2k cash on the rooftop for the thieves to pick up? and hopefully they run away with that 2k?

Yes zinc is cheap and easy to install!

I'm thinking of using roof tile adhesives to prevent burglars from removing the roof tiles. Anyone has any experience on this? Will it be effective?

You have more problem in future, what happen you need to remove it for maintenance? You taking entire roof down?

Furthermore, roof tiles not that hard to break, a hammer is already good to break the roof, how do you intent to strengthen it?

I see. Good point. I know it's easy to break the tiles, but at least the burglar might fine it frustrating and making a lot of noise

I feel it's more difficult to break the timber batten using portable saw, compare to when they can cut the brc using cutter, not difficult at all.

Beside motion sensor, place some sensor on every two tiles? Workable idea?

What are the best options to secure house from rooftop intrusion?
1. adding wood or steel purlins to narrow the gaps
2. using zinc below the roof
3. wire mesh just above the ceiling

Zinc sheets come in several thickness

My contractor recommended G28 (0.35 mm) zinc sheets. Is this enough for roof security?

Really appreciate feedback

Boss..also from experience better board up your two sides neighbouring wall in the roof using 2x4 balau wood and a lot of nails or lag bolts coz we had experience that thieves can come in from ceiling.
