why roofs in Sydney leak only in heavy rain

Some roofs in Sydney leak in heavy rain (and not in light rain) and there is usually only one reason why this happens.
• Water flow exceeds the capacity of the roof elements.
More information at The Roofing Professionals Westside at : theroofingprof...
In my experience, roof leaks can be separated into 3 categories:
1. The roof leaks everytime it rains;
2. The roof only leaks when it rains heavy;
3. Only prolonged rain makes the roof leak.
On this post, I will examine the second category.
Leaks on tiled roofs
The most common reasons why tiled roofs leak during heavy rain are:
1. No sarking under the roof tiles. If you go into your ceiling cavity and you can see the underside of the roof tiles - then you have no sarking. Stay there during heavy rain and you will feel a fine mist coming through the gaps between the tiles. Usually, this is not a big problem because it is not enough moisture to wet the ceiling. And there are no ceiling stains.
2. Low pitched roof tiles. Roof tiles start to do poorly when the roof pitch gets less than 20 degrees. Manufacturers of roof tiles have limits on roof pitches because of this. Yet, many roofers ignore these for the sake of ‘looks’.

Very thorough and informative. Thank-you. Confirms my suspicions as to why we recently developed a leak.... heavy rain-low pitch-torn sarking/flashing. Much appreciated.

Unbelievably useful video. Can’t thank you enough for your generous sharing of your trade knowledge.

I had 4 people came in to inpsect/Fix but couldn't figure out the problem but it is explained in the video.

[@veredictum4503]

4 years later - I'm just seeing this, because suddenly today, drops of water in the kitchen, in the middle! Either the roof itself, or the gutters overflowing. Oh wonderful....

[@itsame1277]

Wow! Must get my wife up here too to watch this! Cheers

Excellent video (apart from the weird psychedelic rotations etc. which make it hard to "orient" where the viewpoint is) . Also, the rain in Sydney appears to be the same type as in the UK - even though it's upside down! Blow me!

When you get multiple roofers who come and say they know the problem but it never works! I’ve had multiple people come yet roof still leaking! Damn frustrating. I bet they never considered the water channels beneath the tiles for example.

[@MagicofJam]

Hi there - just wondering when you will be uploading the video or blog post regarding the "leaks only during prolonged heavy rain" ?

[@mohammedhasan7364]

Thank u

[@Narsty_Boy]

U sound a LOT like the guy from dragonforce lol. Not just the accent but the tonality and the timing you both use are almost identical. Maybe I'm just American

[@blucklightfoxartinnovation9357]

[@2loco]

Good video. In a nutshell, tiled roofs in sydney are fucking shit. Metal roofs are great.

[@petergreaves2914]

Not just in Sydney, but my tiles might be from there ;)

[@deadly3890]

My extension started flooding through the fucking ceiling!!!!!! The stupid builder couldn't even build a proper roof 😠😵, this has happened to my neighbour and we have the same roof and the same builder extended our house!
