Can sifu help enlighten the prons and cons of metal roof?

How many types of metal roof available?

I read some articles and revews said metal roof is noise especially during heavy rain and heat absorption is another cons.

Anyone installed and mind to share your experience?

Thanks

hot on sunny days, noisy when it rains, will rust overtime. installation is easy, many choice of color and pattern to choose from, cheaper and more durable than poly

my friends house neighbor have it installed..

rust is biggest issues.. few years time sure GG one..

not sure about hot time. but raining time very noisy... every single drop of rain sure can hear one.. tap tap tap.. like that... also make sure not always people walk over the roof (for various reason - astro or aircon installation etc.) beacause over time, the metal would bend little... finally have holes / little broken...

Noisy when raining... sometimes sounds like thunder when there is a sudden heavy downpour. My zinc roof (cover backyard) lasted 20 years then had to change cz full of holes and leak.

The new type of metal roof have insulation behind. As thick as 2".

It help to reduce the heat transfer and sound proof.

The good of metal roof is,

1) the roof angle slope can be reduce if the depth not long enough for the roof drop.

2) water leaking.

Thanks enlighten, I saw there are many new housing project using metal roof and not sure what is the outcome.

Are you using the metal roof too?

Mind to share what is the new type of metal roof before?

Thanks

Can opt for aluminium material

More mahal in price ofcos,but oso thicker

More expensive?
Like how much estimate?

Not so sure price exact

3yrs ago my dad wan do some store roofing,he order from Lian Giap

roof is roughly 20x30ft,that time i help sign the d/o bcos i off day go help his company,price is roughly rm3.6k+ on the bill,cash n free delivery.

20ft long each piece very strong no bend.quite thick if compare to normal metal deck.

Heard from dad is much less heat n rain noise slightly reduce bout 20-30%.

Oh okay
Thanks for the info 🙏

the roof angle slope same as clay tiles? my problem is the roof angle slope

How easy/difficult to install?
I am extending my DST at the back, but my roof is too sloppy, can only do RC roof, which I am scared of leaking in the future.

It is same as metal deck/zinc roofing sizes just like u c at factory roofing

come in long length piece,just material is aluminiums.way much better durable than metal deck/zink roof

One thing for sure the bangla will wtf to screw them bcos thickness lol,but quite safe as they step on it no kemek during installation,very tough.

U can contact Lian Giap ask for available color, design,size n thickness...they can cut for ur desire size each pieces,like u wan 10 pc 10ft long + 15pc 5ft long oso can via their machines cutting nicely.so tell ur contractors measure cun2 size needed.

You have to make sure the water proofing for the RC slab roof been done properly.

There are different roof profile to suit different roof slope. And the insulation can reduce the heat and noise from the metal roof also.

How long can a rc slab roof last vs concrete tiles ? What sort of maintenance is needed for rc slab ?

Thanks enlighten. Can you share with me the supplier contact?

What you recommend on the insulation? Additional foil or sponge? Thanks

The invoice duno where adi..lol

But i think u can google online,Lian Giap aluminium, roughly recall the address at chan sow lin

Still in clay roof. It's original roof like normal house.

I intend to change the roof and decide to use metal roof.

Most important is not leaking, heat insulate and noise.

Since the metal roof improve alot from the old generation and solve the 3 issue, should give a try.

The contractor said cheaper also. That I ask back 5yrs ago. Not sure now.

Sloopy won't have issue with leaking for RC roof. Only aging than start to leak. workmanship too.

When it not enough sloop, than it will leak in as the rain storm water cannot fast enough to flow away from the roof.

So metal roof solve such issue. As metal roof don't have gap between. It is 1 pcs all the way.

I have these metal roof with insulation foam and a layer of heat insulator.


Very good in heat insulation and no need for another layer of insulation material above the ceiling.
Noise level is minimal and the roof sloop can be less than 30 degrees.

Only problem is some leaking from the "nailing" point where the workmanship is bad (did not apply the silicon properly before nailing).

Pretty common such leaking for metal roof.

If you fix it, makesure use the nail/screw with insulated. Than further apply with silicone caulk or RT silicone. Those that can stand the heat. Not normal silicone.

Double protection last very long.

hey there, I'm sure you have solved your issue by now, but since you posted this i had a similar case like yours a couple of months back, and regardless of the roof you choose its really up to you all of its pros an cons, of course on top of all is the cost la.

i think the most important thing is to consider the long term expectations you have, as you know metal roofing vs clay only has one issue. the Sound it makes when it rains, and heat absorption during mid day sun, but if you have decided to use metal roofing, there are ways to make it sound proof, and more resistant to building up heat, my Uncle Mr Teh ( contact below ) can quote and do this for you.

But if you or anyone, ever face this same issue again you can call my uncle Mr Teh 012-6721130 .can Call /wassap

I recently also launched his website at https://mrfix-leaking-roof.com/ been around for the last 15years, if anyone can stop your leaks or give you the best price for metal or clay roofing its him ! Hahah support yah! thankx

Hope you don't mind I ask after 1 year , I am going to install the metal roof. Did you use the Clip-lock version?

As for the insulation, my future house is facing afternoon sun. The contractor originally proposed a layer of woven fabric and double-sided aluminium foil. I think it is not sufficient. He then proposes the insulation foam. It appears that this sort of foam has 7 layers.

Did you install the solar-power roof ventilator?

It depend on the roof slope to choice the type of roof. If you have budget, clipping system is better.

For the sound insulation and heat insulation, you have to install a layer of aluminium foil ( not metalise foil)and a layer of rock wool.

Yes, my contractor suggested that and showed me the sample of the aluiminium foil and the rock wool.

The slope is 28% and he quoted metal lock, I presume it is a clipping system.

However, as DBKL cut away a tall and old tree, my house is fully exposed to the direct afternoon sun. Very hot and I am trying to look for double protection.

Then you can go for a sandwich roof

Hey all want to ask. What is the aluminium roof mentioned here? Also planning to change my house roof to metal roof, can't afford to do back the clay tile as it is too expensive.
And how bout spandek, any type specially thick enough and have heat/noise protection?

Im also doing some preliminary survey, dah sakit kepala

Lets see if Pucca&Garu and ongss further insight? Thanks

DO they last long? do they rust once the top coating damage or fade away?

Does the color last?

I have selected the vendor but have not installed yet. I am installing a local brand Astino with thickness 0.48mm click lock and the vendor's quotation includes

Light weight truss,
Small bubble foil,
50mm thk 40kg/m3 rockwool insulation,
600mm girth 0.47mm thk PPGI ridge capping,
fascia board (UAC Prima Plank cement board)
450mm girth 0.47mm thk PPGI gutter
600mm girth 0.47mm thk PPGI fire wall capping

Per sqft is about RM 24.50. Not sure if it is cheap or expensive.

Which metal roofing you are going with? WHats the warranty on the roof?

how much did it cost for the whole roof?

I was looking at spandec/spandek as well

Thanks bang!

btw, another company Im reviewing is
https://www.lysaghtasean.com/my/en/products...ing/pierce-fix/


My hubby prefer to go with clay, but I wanted long lasting and the roof leaking is killing me, as our house slope is not steep, hence alot of backsplash and leaking. Thinking of also, maybe just place a zinc and reuse my tiles on top of it...lets see how much it comes to.

I am going with clip lock 672. For this metal roof, I was told that there is no drilling and fastening.

https://www.astino.com.my/products/astino-r...p-lock-672-710/

If there is a drilling and fastening with screws, I was told that workmanship is critical and also the rubber washers need properly seat against the metal roofing panel. Otherwise, it will cause future leaking. About the noise and heat, I was told the rockwool and bubble foil should solve the problem. But, the neighbour may hear the noise or face the reflection. Hence, have to choose lighter color.

My immediate neighbour is using metal roof for her kitchen extension. I noted the color fading. But, his extension was done long time ago. There are several houses around me are also usng metal roof.

For my case, my area is about 1815 sqft. So, the total cost is around 44k.

Hi there. Did you install the metal roof?
If yes, how many sqft, total price and material you choose.
Thanks in advance.

Hi deadboy, no we havent install yet still looking around.

I'm also looking for PUMetal awning supplier+installer in Klang Valley area. Any recommendation and what is the average price persqft? is 20mm PU thickness good enough for noise insulation?
