Hello all,

I was quoted 3.5k for roof top waterproofing for maintenance service as the house in question is a subsale and has never seen any renovation before.

I asked what kind of maintenance work for the roof top waterproofing and was told that the contractor will go up to the roof to check the condition of the roof to determine if it is in good condition or not and do the protection coating for the roof top.

Is the price reasonable for this roof top waterproofing maintenance service?

What type of roof? concrete slab or concrete tiles? i guess it must be concrete slab, am i right?

No, its not concrete slab. Im not sure if its concrete tiles either because the house is 20 years old and the roof tiles are the same as day 1 since it was built because as mentioned before, the house has never had any renovation done to it before I bought it.

That's why Im not sure if the price quoted is reasonable or not since the price varies ALOT in between different contractors quotations.

very funny. just like u pay 1k for mechanic to check any problem with ur car n if got problem he fix. if not? he pocket the money? i got quoted around 3k for putting a layer of zink sheet underneath the tile roof. this method is to prevent leak n thief. i think more worth it than put a coating

You need to ask what is the material use for "protection coating", I paid my contractor 3k, he use high pressure water to wash the roof tiles, apply primer, and final coat is Nippon roof paint. That was 2011 price.

Roof tiles after so many years water may slip through, and is better to paint. But If you are not renovating or leaking why do it? Fix it only if you need repair. Or you want to change roof tiles color?

You do have a point, I need to find out more. I heard from another contractor its better to put grilles under roof area to prevent thieves though.

Thank you for the advice regarding the protection coating! Will ask the contractor about it.

That's the problem with old houses. I don't know how is the condition of the roof as the house is already 20 years. I know of a friend whose house is more than 20 years and there are long hairline cracks around the kitchen wall in the back of the house. It is a potential danger problem for him and he has to redo that kitchen side soon.

So weikee, did nippon roof paint help in your case? I had half a mind on whether I should paint the roof or not since I intend to have the house exterior painted too.

Is it better to change the roof tiles? It already 20yrs.

I renovate, and repaint my house, so painting the roof is cheaper way to make the hosue nicer. Don't know what you mean on help me, but for me is cheaper alternative than changing the roof tiles. The Nippon roof paint provide water proofing for at least 5 years. Hope by than I have enough $$$ to change the roof tiles.

If it ain't broken why change it

Do checking urself during raining day or better downpour..see any obvious leaking where water drop to the ceiling..if not satisfy, open the manhole and look at the attic whether any water drop o not...observe for few weeks or few raining days....
If there's a leakage, make sure its bcoz the arrangement of the roof tiles that give way or any kind of defects..
Do this first so that you will have some idea what is going on in your roof and t
Else the contractor will just go up during sunny day and simply told you there is few points of leakage and will repair it for you and apply some donno what to the roof top and charges u the 3.5K.

weikee, I mean.. does the nippon roof paint help in preventing any potential leaking problems since you move in?

I see. I will try to go down during rainy days and check whether any leaking problem. As for going to the roof - I'm not good with heights + I'm a total klutz, I don't think I can handle going up to the roof myself.

Not sure how bad is it after 20yrs. Also there is a condition where some is in bad shape and broken. You will have difficult to find the same shape and design tiles roof to replace. If it doesn't cost much to replace, why not.

Changing to normal roof tiles can be around 6k or more. But newer roof tiles quality are not as good as the old tiles, can be worse. This was what my contractor told me.

If change better change to the roof tiles with coating (glossy type) think is ceramic coat. But it can cost double.

u must ask the contractor get the checking 1st before quote u ..And i think the roof 20 years is nt much functioning as well . If still in good mantain , maybe u only can put coat on it ..but this only can keep maintain temporary . Better is change to new 1 ..

The best roof tiles to replace is those new awning type. Combine with heat insulator, it is cheap, light weight, waterproof and thieftproof. The problem is, can you accept the design. Cause it look cheap.

Hm, roof tiles are sure as expensive as installing new floor tiles

But I should think its not that bad condition because the house was previously tenanted before I bought it although the tenants didn't maintain the cleanliness of the house well.

Crossing my fingers that the roof tiles are in ok condition.

Ozak, you mean those awning as in polycarbonate roofing? If so, I was thinking something like those flat ones used for bus stop shelters in singapore.

Does anyone also have an idea of the cost for pergola roofing used in car porch area (JB side) - I want to extend the car porch roof but the cost for concrete slab roof is really expensive for a car porch - was quoted a high cost for a full concrete slab and 10+k for half concrete slab roof add on to the existing car porch roof

Paint / coat is not few hundred ringgit job. Need to wash the roof tiles, and apply sealer only put the coat. That itself is few thousand. Maybe that is what TS contractor quoted.

My direct opporsite neighbour change his house roof tiles to something smaller think is about 1/2' x 1', and is black color, don't know what is it but sure is flexiable and rubber like.

Weikee, will confirm this with the contractor later when I ask him to revise quotation.

BTW, your stained acid floor looks good.

The awning type is something like this --> http://pinterest.com/kelliesmyers/awnings-and-metal-roof/

It is normal for western country.

Here, it getting famous and often you see from those new design house. 1 of the reason they using awning type roof is, the angle of the roof no need to be too step.

Nice awning, can accept this kind for car porch roofing but it doesn't look like its for the roof top. I wonder if have those metal roofs, the flat strip section here cos it looks like it could be an alternative to roof tiles.

I don't have any idea on quotation but I suggest you better start consulting with a waterproofing expert just to make sure.
