Why replace a tile roof with a colorbond roof?

Why fix it if it ain’t broke?

replace concrete tile roof with colorbond roof

This is what Tom did!

Tom had an old  tiled roof.

It happened to be old concrete roof tiles and he often wondered about its age and whether it was time for a new roof. Initially, it was a low priority item for him because he had just spent a few bucks on a new kitchen.

… Until a storm showed up.

The kitchen ceiling started to drip. It was an emergency but there were no roofers to be found.

“… it is against Occupational Health and Safety regulations to send a roofer up on a wet roof in windy and wet conditions…” – was a typical response.

Only the SES could help (apparently they worked under a different set of laws?).

“ An old dried up tree branch fell off the back gum tree. It cracked a couple of roof tiles. We have put a tarp over the area and you will need to get a roofer out when the weather gets better…” The SES guys were great.

Storms keep roofing crews busy – and it was a good two weeks before a roofer was able to peel the tarp off and take a look.

“…Yep. A couple of cracked roof tiles. They are ‘Boral Windsors’. Bloody hard to find replacement for these now since Boral stopped producing Windsors a few years back…

Lucky for you I have about 5 in my yard”

This was the good news.

The roofer had more to say….

“ You will need more work on your ridge capping because the broken tiles are directly under the ridges… Also, there are quite a few loose ridges. Maybe the SES or just a maintenance thing…

Probably about $3000 to do a proper fix.”

 

Time to make an executive decision.

For Tom, it was decision time.

He had a healthy balance on his line of credit.

The roof showed multiple dips (maybe because the roof tiles were too heavy?)

The roofer had said that if there was sarking under this roof tiles, then maybe it would have kept the kitchen dry.

The roof was hot – even though he had put a couple of whirly birds in a couple of summers before…

So Tom started researching.

He was after a roof that could withstand a falling branch. Looked good and straight. Had less maintenance issues …and a bit cooler.

Initially, he was looking for a new replacement tile roof. Then he read all the talk on the internet about colorbond roofs.

He Googled ‘replace tile roof with colorbond roof’…. And up popped a whole page published by a roofing materials supplier called ‘No 1 Roofing’.

All the pros and cons of tile vs colorbond roofs.

Tom made a decision. It was too easy…

It was going to be a new colorbond roof!

… Now, all he had to do was find a good roofer.

replace terracotta roof with colorbond roof

It was 2014 and Terry saw the Colorbond ad on TV.

One day…. He was going to be able to run out in his pyjamas and admire his new colorbond roof. His old terracotta tiled roof looked crap, the tiles were very fragile. And the look of the tiles did not match with the other metal roofs that were hanging off it…

Terry also thought: Maybe new guttering…and colorbond fascia covers…

That was Terry’s dream.

In 2017, It came true…

When roof tiles just don’t work on a roof…

replace leaking low pitched roof tiles with colorbond

 

“… it is just criminal how builders and roof tiles get away with their ignorance and laziness about where tiles just don’t work!” – my roofers regular rant.

It is a fact that most roof tiles struggle to keep the heavy rain out when they are laid at anything less than 20 degrees.

Roof tile manufacturers say that putting sarking under their tiles will stretch the minimum tile roof slope to as flat as 15 degrees. If you read between the lines, this reads: “We know that the tiles will leak – but the sarking will catch the leaking water and carry it to the eaves. Hopefully, no water will reach the internal ceilings…”

… And they are mostly right.

Until 10 or so years go by.

The battens that sit on the top of the sarking, goes through hundreds of wet/dry cycles and start rotting. The roof tiles lose their support and collapse to a flatter position and cause more leakage. This is when water starts dripping onto the ceiling.

When it comes to roof pitch versatility, Colorbond metal roofs come out the clear winner over roof tiles. You can build a colorbond metal roof from 1 degree to a 90 degree pitch. You just cannot do it with tiles.

Some tiles are better than others…

Terracotta tiles are generally better at handling the lower pitches. The interlocking upstream edge will prevent water from overflowing the top edge of the tile.

Concrete roof tiles do not come with any ridging on the upstream edge. Water will run over the top edge as the roof pitch dips below 20 degrees.

The flat profile concrete tiles tend to be worst. They leak everywhere…

…. And then you have leaves.

Trees are great.

But they drop leaves on the roof.

Leave clog up the water courses of roof tiles and block the natural flow of water down the tiles (especially flat concrete tiles).

 

Colorbond roof replacement leaves on flat concrete tiles

In our many years of replacing tile roofs with colorbond roofs, we consistently come up against the two main enemies of roof tiles.

Trees and low pitches.

So when you are considering a tile roof, you need to take these into account first. You may end up going with colorbond.

I often tell people that I am extremely biased towards colorbond – BUT they need to take it with a grain of salt because we only do colorbond roof replacements.

Of course we are biased.

The No 1 Roofing post I mentioned earlier is an independent view about replacing tile roofs with colorbond. It does have a lot more information about the topic than I have covered above.

The best tool for turning down kliplok profile roof sheets

We know the importance of turning down the ends of kliplok roof sheets.

And like everything in life, the right tools makes the job easier and produces a better finish.

Sadly, the standard tool that we buy to turn down the ends of kliplok sheets is a disappointment and produces a sub standard result. It is even dangerous because it slips prematurely.

And for a while, we have resorted to using the trimdek tool to do turndowns on kliplok sheets.

Even though the trimdek tool is designed for a narrower pan and we had to perform two lapping actions to complete a turn down.

Then my guys discovered a neat little trick.

If you reverse the trimdek tool and use the turnup end of the tool to perform the turn down – it produces a perfect result.

We can now throw the standard kliplok turndown tool away and just carry the more versatile trimdek tool in our tool boxes.

Just a note that the trimdek also has an integrated  corrugated sheeting turnup jaw

ZINCALUME® steel AM125 – the new standard for metal roofs

Metal roofs keep getting tougher.  Around mid 2013, Bluescope announced that their old zincalume was going to be replaced by their new (Next Generation) ZINCALUME. We are now seeing the new zincalume branded products coming from our suppliers. What is the Next Generation Zincalume? ZINCALUME® steel AZ150 was the ‘old’ […] Read more »
