You staying in condo unit or landed?
If landed, then u can DIY.

Landed but i dare not to climb up to roof..its a pitch roof. Better get a sifu to do it once for all..

Yup safer to get the pros for it. Our roof in MY not fully boarded up like US shingles roof, risk of falling thru is there.

Ok...better be safe then.

Hi all, wanna ask, is PU zinc roof very noisy compared with concrete/clay tiles? for a double storey house 22x70

My ultimate concern is to eliminate potential thieves breakin and leaking problems. but not sure on the noise levels. if only slightly noisier i still can live with it.

Zinc roof like some school canteen or roadside mamak stall is rather noisy when raining..

What u mean is those zinc roof with no insulation one. yes that one is damn noisy.

I am referring to another type, still the same zinc roof, but with PU foam underneath the roof. The pu foam is like a cushion.

Currently another house got one area of 14 x 16 with this PU roof, the noise level is not so noticeable. just wondering anyone is having this type of roof at home can share their experience.

Ahh it should be less noisy.. you can experiment spraying droplets of water using a hose on ur existing installation. As there's also ceiling board to further dampen the noise it shud be ok..but good to hear other users' feedback too for the insulated zinc.

Thickness of PU foam plays a major role in dampening noise, and to answer your question, yes. It's even good enough for attic. That's how quiet it is.

I replaced and rebuild a lot of residential and commercial roof with this. Get PU metal type of metal deck roofing if you want the PU foam to last.

Hi guys, my contractor advise me to put a layer of zinc sheet underneath the clay tiles for better security. However, I've plan to put this kinda Aluminium foil in my roof system for better heat insulation as my house is a single storey house that facing west and Im kinda worried the heat during afternoon hours.

My question here is, will the aluminium foil does the job as the zinc sheet in this case? So that I can only put aluminium foil and save the cost for going zinc+aluminium foil instead. Tq

Recommend using monier radenshield eg https://shopee.com.my/product/286308151/5353840667

It does work but its not supposed to stick directly..it need an airgap to work.

The heat reduction is minimal but it does helps to prevent a leak from dripping onto to the ceiling board.

The house feels hot due to the accumulation of 'stagnant' heat overtime between the roof and ceiling during prolong warm days.

So in that says that it’s still fine to just place a layer of monier radenshield but it just doesn’t work like zinc+ aluminium right sis? And have you tried this monier radenshield before, is the heat reduction well? Thanks

Thanks for your input, Urm… I think I shall gather more feedback on this whether it’s economically to put the aluminium foil then.

Basically the radenshield is mounted say 2 inches below the roof tiles.. the mounting u can use existing roof batten as support like in https://www.insulation4less.com/installing-...insulate-a-roof or mount it on the bottom side of the battens..

This airgap of couple inches or so is the key for it to work. Heat comes in 3 ways, convection radiation and conduction. Sticking the radiant barrier (foil) on the bottom of the zink (with 0mm gap) defeat the purpose

Your choice of radenshield or other alu shield..personally i think radenshield works well when installed correctly (eg top floor of double storey hse) and its bomba approved not to be easily flammable.

Bang, have you completed the roof work? How much was final cost and can you share the contacts, please.

Im in pretty much the same predicament, and sourcing for contractor to either replace my roof or repair with zinc.

Dah sakit kepala dah...its really costly to change the entire roof (40-45k, subang area)and still not sure if future leaks. I think most likely batten problem, bot most of them would want to make money right, climbing the roof and doing a small job is not cost effective for them, hence most recommend to change a larger potion.

Prior to this I have also made could of minor repairing using foreign contractor, but nothing lasts. Tkasih!

You sure is 45k just for changing roof tiles ? No other work involve ?

1 roof tile cost about 2.50 per piece. If workmanship is also 2.50 ... total 5.00.

2,000 pcs x 5 = 10k.

With current rainy season put on hold. Btw what is your roof size? 40k is rather high.

Its including minor wood and gutter replacement and side wall metal sheet(sorry forgot whats it called).

yeah I think its expensive as well

From my previous callings of multiple repairers over the las 7yrs or so, I dont think its roof issue its just the batten problem.

But I guess trying to fix just the batten is ot cost effective hence they suggest to a bigger replacement/project.

Some suggested to place aluzin sheet at the bottom and then place the current tiles on top of it. Finding where the leaking is not feasible it seems, do agree with this as well, its ot easy to find out the leak.

BTW, 7 yrs ago I had placed Aluminium Foil thruout my roof but it started to leak again, only during dec/jan when the rain is heavy and windy. ANd over the years been calling so may others and all failed depite paying so much. It only drips during really heavy-windy period, tapi leceh la, everytime need to run and get a bucket and ceiling all gets stained.

And during these repairs, those technicians had to cut open the alu foil to troubleshoot where the leak is, hence on some location these foils are cut open as well

BTW build size is 1800sqft. My hubby is in suggestion replacing the tiles, but I dont think thats the issue if its the tiles, i would have more leaks but it seems only the joints and roof merger location and wall.

If you could throw any ideas/suggestion will be good. Any repairer contact as well. Tkasih

maybe will drag in ceo684 sis as well

Hi, I'm not sure whether you're SS subang or USJ Subang. Roughly speaking from memory of SS-area Subang roofs, some have unorthodox designs better suited to warm and dry places.. not so suited for MY wet weather.
So these designs, they collect water at the seams and by now (the house age well into adulthood) rust thru zinc plates/mold at the wall.

First priority is to locate where the water leaks in.

You may want to do selective replacement of the ridge lines/seams (recommend Monier stuff) as there's the prime suspect.
Targeted roof tile replacement probably needed as there may be one or two that are not full tile. Instead of calling roofing people which are NOT that great in troubleshooting, they are better at INSTALLING lah let's just say - why not try to get a home inspector (those people that usually do defect checking for new VP property) with an IR (infrared/thermal imaging) gun to see where are the cold spots where water drips in. That is because water can blow through the gaps of either ridges or in between tiles.

This may entail creative solutions as setting up a scaffolding tower or two + water jet machine to simulate the effects of rain blown in. Still cheaper than complete roof replacement. Normal houses can't really walk around easily so you might also want to consider upgrading the "attic" to be walkable - it will take awhile to notice where it leaks - you can use metal grates (expanded metal mesh) + support beams so that its easy to walk around the whole area. The attic space is hot, that's one problem in itself and doesn't lend itself to extended troubleshooting whilst trying to balance on the rails (trying hard not to fall off into the ceiling).

Reasons Why Your Roof Is Leaking?

It’s critical :( to recognise the warning signals as soon as possible and comprehend the causes of roof leaks because this is a problem that may quickly cost homeowners a lot of their time and hard-earned money. Even if the first indicator of water damage may be a small trickle from the ceiling, you need to act quickly to prevent any problems from getting worse. Unwanted water infiltration could have already done major damage to your property.

We are aware that finding a roof leaking may be a headache for homeowners because they can be exceedingly difficult to assess on their own. Keep in mind that your roof serves as your home’s first line of defence against the weather. We’ve put together a list of the 10 most frequent causes of roof leaks. :idea:

1. Age
Furthermore, Mr Roof is committed to giving the highest quality service possible. Mr Roof conducts rigorous and frAlthough it can seem like a straightforward one, ageing is the main cause of a leaky roof. Due to constant expansion and contraction, weather wear and tear, and other factors, materials like roof tiles and metal roofing can deteriorate over time. Age and time can also compromise the structural integrity of various roof components. To ensure that your roof is still within its life expectancy, schedule a checkup.

2. Holes
Your roof’s hole is a clear entry place for water. Nothing prevents the water from entering your house directly. If you don’t take care of your roof, holes may develop over time. Additionally, if something strikes your roof, they might occur suddenly. Taking items off your roof is another potential source of holes. When an old antenna or satellite dish is removed, it could leave holes where they were fastened to the roof. If anything is taken from your roof, make sure the holes are properly patched.

3. Broken or Missing roof tiles
Broken roof tiles can be very problematic, especially when it rains a lot. As a result, moisture will now be leaking into your attic, burdening your underlay and seeping into the structural timbers, where it may cause problems like condensation, decay, and dampness. The tiles can be easily replaced to resolve this problem. The tiles will need to be pried up, and new ones will need to be put in place. However, you might discover that the undersarking has started to decay as a result of dampness and will also need to be replaced.

4. Slope
Damaged or slipped roof tiles are frequently the source of a roof leak. Any forms of damage, like falling debris, will probably have an effect on your roof tiles because they serve as the primary form of protection throughout the bulk of the surface of your roof. Although many roofing materials are designed to be extremely strong, they have a maximum load capacity before failing. It’s not difficult to spot cracked or missing roof tiles, and after strong winds, your backyard garden may have complete or chipped tiles thrown around.

The risk of wind-driven rain increases if the roof slope is too shallow. The ratio of the vertical rise in inches over a horizontal distance of 12 inches is used to calculate the slope or pitch of a roof. According to the International Building Code, asphalt shingles can only be installed on roofs that slope at least 2:12 degrees. It is necessary to utilise two layers of underlay material if the slope is between 2:12 and 4:12. Verify that your roofing materials have been fitted correctly and are suitable for the roof pitch.

5. The Valley Gutter
Valley gutters gather rainwater from two steeply pitched roof areas and direct it to lower perimeter gutters. Older valley gutters with flattened turnbacks might have surplus water shoot over the edge due to wind speed and direction as well as the sheer amount of rain. The safest places to walk on roofs are up and down valleys, yet unskilled feet can damage valley gutters and cause leaks that need to be repaired by locating the leak’s source.

6. Seams
Your roof’s seams are often its weak point. Substantial rolls of membrane are spread across the wide surface of a business roof. Those membranes are fastened to either the insulation or deck below, depending on whether the roof is mechanically fastened or totally adhered. The fact that no sheet can be as wide as a roof necessitates the overlap and joining of several sheets using hot-air welding or glue. These seams perform admirably in flat, open areas, but delamination around the roof’s edges, particularly near flashing, pipes, or the location of a previous patch, can cause a roof leak.

7. Poorly Placed Fixings
Failure to attach roofing nails or screws into the rafters is an easily avoidable cause of future roof leaks. Missing the rafters results in a nail sticking out into your roof area, providing a direct path for leaks and water infiltration. These are particularly problematic right after a cold spell because the nail may frost over in the cold, but as it heats up, the ice transforms into water and starts to trickle down. Poorly insulated or aired loft spaces have the potential to worsen this problem since they serve as breeding grounds for excess moisture. Simply pry the fixing up and cover the space it leaves behind to correct improperly installed fixings.

8. Vents, Skylights, and Chimneys
There is a chance that the chimneys, skylights, and vents on your roof will leak. These elements may have gaps along them where water can seep into the house if they are not put properly. Those elements will be sealed and watertight if they are installed properly. To keep them safe, you might need to have them resealed from time to time. If the hole doesn’t perfectly fit the size of the skylight, leaks may enter. Additionally, with time, the insulation around the skylight may weaken and permit leaks. Another potential leak source is if the window itself has cracks or other damage. Over time, chimneys may degrade and let water into the house. Possible causes include gaps in the chimney and damaged or missing mortar.

9. Damaged Soffit or Fascia Boards
Soffit and fascia boards safeguard your roof area by obstructing access to the front or beneath for water or harmful critters. However, these can deteriorate over time, especially if your house has conventional wooden soffit and fascia. The wood may soften in conjunction with problems like leaking gutters, which can drip onto your home’s façade, eventually leading to holes and rot. The result is that these spaces attract pests like rodents or birds as well as water intrusion. Modern UPVC is the material of choice to replace the soffit and fascia boards since it is essentially impervious to all of the problems that conventional lumber is prone to and is far less likely to result in roof leaks.

10. Punctures or Pooling Water
The most frequent reasons for flat roof leaks are acute damage, such as collisions that cause tears or punctures, or collecting water as a result of incorrect installation. As breaches in the roofing membrane or felt present an easy opportunity for water to get in and as pooling water increases pressure on the material and structure underneath, both of these can quickly result in roof leaks.
