[Progress.075] AirCon pipes connected, ground floor roofing almost finished...

There will be 2 sets of photos from past 2 days shown in this post.
First set were taken yesterday (06/12), this one shows the whole ground floor roof covered in sarking. The machine used for moving roof tiles was back again.

This one shows part of the alfresco roof at the back. You can see the sarking (shining silver coloured), fascia (creamy white) and gutter (dark grey). And I think the light grey coloured board at the bottom of the sarking is the "anti-ponding board".

This one is from the bay windows at the front, also showing similar details as the previous photo.

I was quite happy to see these shining air conditioning pipes been installed.

I can roughly see this air conditioning pipe in the first floor ceiling which looks like an alien...

Don't know what is this, looks quite complicate to me...

The whole alfresco roof is now covered by sarking, as it blocked the sun light, looks a bit dark compared to before.

After so many days of rain, the alfresco floor is now flooded with water. I start wondering whether it worth the money we saved by doing the slab after hand over...

The last photo shows a new grey pipe at the side of the house, connecting straight to the first floor roof. I think that's for the air conditioning as well.

The second set were taken today from my mobile. Early this morning, there were 5 guys working on the roof. It was cloudy but an afternoon storm was forecasted, I believe they were like me, trying to get the roof covered before the storm. Before I left, I confirmed with them the first floor roof hip issue raised last time will be fixed.

The storm this afternoon was quite strong and according to the radio, it caused lots of damage. As I was quite confident about the roof been fully covered, I wasn't worrying at all. Late in the afternoon, as shown below, it looks quite good with the whole roof covered... Then I noticed something wrong...

The hip on the first floor was indeed fixed, but the area under the 2nd and 3rd window from the left, behind the front porch, wasn't covered at all!! What's going on??!! I can't imagine how much rain has flow through that huge hole during the wild storm which lasted a few hours...

This is from the other angle. The resolution from the mobile camera wasn't that good, will try to take a few more better ones this weekend.

[Progress.071] Sarking installed, but is it strong enough for the storm without the roof tiles?

I having been talking and worrying about the coming storm since last week, but seems that the more you wish something to happen, the more it will go against you...

We had beautiful weather for the past few days.
On Monday, nothing happened...
On Tuesday, nothing much either. Only thing was, someone removed all the wrapping plastics around the roof tiles... As shown below, there seems to be quite a number of broken tiles...

This one from different angle, a few more broken tiles. Hope these shining dark grey tiles look good when placed on top of the red bricks...

There were a few bags of these small soft foam things been delivered as well, not sure what's that for...

Late this afternoon, we finally have some activities. Didn't have my camera with me, so only took a few not-so-clear photos from my mobile. Need to walk across the street as our house is a lot higher than the street level. From photo below, looks like they have finished installing the sarking.

But, what about the roof tiles? There's a storm coming tonight/tomorrow morning, how are these thin sarking paper going to survive the storm and protect my timber flooring/frames without the roof tiles??!! Don't they ever check the weather forecast and plan their work accordingly??

They finally have this machine installed, looks like it's for delivering the roof tiles to the higher level. Can't understand why they didn't install this thing earlier during the brick stage. It would cut down at least a week's time and save lots of effort as the brick layers won't need to manually handle the bricks...

If you compare the above photos with photos from previous post, you might notice now that the roof area been blocked, the area inside the 1st floor windows seems to be a lot darker now... Hopefully when the white ceiling been installed, it will look better...

[Jargon.002] Sarking and Anti Ponding Board

Our builder told us that, because we are using "Terracotta" roof tile, we need to install "Sarking" and "Anti Ponding Board". This post is to talk about what I found about these 2 Jargons...

What is Sarking?
I found this definition of "Sarking" from the internet: "Sarking is a reflective foil laminate that is installed inside roofs. It has many benefits including weather proofing, insulation and reduction of dust and sound". The image below shows what it looks like:


The drawing below is from this page on greenhouse.gov.au, it clearly shows how the sarking are installed under the roof tiles. "RFL" stands for "reflective foil laminate".


The next image shows how sarking been installed: start from the bottom, with some overlapping when installing the second one. This is to ensure that if there's any water, it flows down to the gutter.


What is Anti Ponding Board?
So "sarking" is not that hard to understand, it took me a while to work out what is "Anti Ponding Board" used for.

The most simple and easy to understand explanation I found is from harmonyrooftiles.com.au: "The boards are installed to support sarking and ensure that any water collected by the sarking is correctly discharged into the eaves gutters."

The drawing below is also from the same page mentioned above from harmonyrooftiles.com.au:


The drawing below is from this page on bristileroofing.com.au.

So this "Anti-Ponding Board" thing is installed at the edge of the roof, and under the sarking to allow waters collected by the sarking to discharge into the gutter.

I remembered one of the Clarendon sales strongly recommend not to install sarking. Her reason is, if there's a crack somewhere in the tiles, it will be very difficult to work out which is the cracked tile. Because the water will run all the way to the gutter because of the sarking... Hang on, what are you talking about? That's one of the main reasons for installing sarking: to prevent leaking water from damaging my roof/ceiling! I would certainly prefer to have this extra protection than water damaged roof/ceiling!
