Roof repairs to leaking roofs in Sydney’s inner west pose unique challenges to Sydney roofers. One-way congested streets, high terrace houses, limited parking and rampant parking inspectors make it hard going…
Where are we working today?” my roof repair crew asks.
“Newtown”
They all give me “that look…”
Because roof repair in the inner west of Sydney that they will be doing that day will be an interesting one…
Of all places in Sydney’s inner west, Newtown, St Peters, Balmain and Erskineville must have the worst streets for tradies.
The multitudes of dead ends, one way streets and parking congestion makes getting in to do roof repairs a long drawn out process.
My roofers now know that to get a parking spot, they have a small window between when folks leave for work and when businesses open. Then they need to be continuously wary of the parking inspectors….
Getting in and out is one thing, there are other ‘roofing things’ that we need to take into consideration when roof repairs in the inner west of Sydney are on the day’s agenda…
Like getting roofing materials through the streets of the inner west…
Our roofing material suppliers usually deliver roofing materials directly to a job site. But we do not have this luxury in the inner suburbs of Sydney. Not only do big trucks find it difficult to get into the tight streets, there is not enough space to stop and crane off the materials.
There is a ‘double handling’ process where materials are offloaded onto our little utes – which then go in to the job. The utes become the delivery/storage mechanism. But sometimes, the materials are too long for the racks of our utes….
I remember a roof repair job in Erskineville.
It was a terrace house with a flat metal roof. and the roof was beyond repair. We had to replace it with a colorbond kliplok profile roof. The roof was 10.5 metres long…
We did not want to engineer a step-joint and split the sheets into two short lengths. So, the10.5 metre sheets were ordered in single lengths.
...And they got delivered on a semi trailer.
“Sorry”
“There is no way we can get our semi trailer down THAT street!…” mister Lysaght told us. “The closest we can get is 2 blocks away.”
So, what was the solution?
Can we get a crane into an Inner West street in Sydney?
“No way” says my crane company.
The streets are so narrow.
Roads will need to be blocked off.
Power lines everywhere….
This means that we are back to my roofers physically carrying roofing materials to the job site and passing the materials up onto the roof. And there are some steep roofs in the Inner west!
So, for this roof replacement job in Erskineville, my roofers had to carry the 10.5m roof sheets (from the semi-trailer drop off point) along the street/footpaths for 450m – before reaching the roof they were working on. They had to have a rest before they had enough energy to man handle the long roof sheets onto the second storey roof…
When my roofers work in the inner west suburbs or Sydney, they need to be ‘zen-like’ and learn the power of “slow and steady”. It may be “back breaking” – but think of the savings of gym membership!
No rear lanes in the inner west of Sydney for roofers?
There are rear lanes – but not enough of them. Rear lane access makes life of a roofer a lot easier to get materials onto a roof that they are doing repair work on.
But there are many houses in Redfern, Paddington, Surry Hills. Ultimo, Glebe, Marrickville, St Peters, Annandale, Leichhardt. Balmain etc that only have front access. This means roofing materials for the roof repair job need to go through the house, or up the front roof.
The Balmain area has the steepest house blocks and many streets without rear lane access. It is a fight to get roofing materials from the truck to the job. This is when getting roof repairs done in the inner west of Sydney can turn into a a long day…
Leaking chimneys and parapets – the bane of inner west roofs in Sydney
“I have a damp spot on my wall”
What has a damp spot on a wall got to do with a roof repair?
The inner west of Sydney has all these terrace houses divided by common walls which protrude above the roof line and form parapet walls (and often chimneys).
These are the things that leak. And they become a roof issue.
Inner west parapets and chimneys – the favourite roof leaking spots
That is why my roofers fix a lot of roof leaks around parapet walls and chimneys in the inner west. Old lead flashings along the parapets break down over time and soak water into the walls. Cracks on the parapets allow seepage into the walls.
This water seepage gets behind the paint and plaster on the walls. Ugly bubbles then appear and the paint peels.
The Inner west of Sydney is a ‘hotbed’ of renovation work. And chimneys inside the terraces are knocked down and removed to make way for more room.
But the bit above the roofline remains…and if it is not properly capped and sealed…
Getting a leaking chimney repaired in Sydney's inner west
Leaking chimneys are not only confined to Sydney’s Inner West. They are everywhere in Sydney…
Chimneys leaks show up as brown staining in the ceiling area that progressively gets worse. This is usually caused by a deterioration in the flashings around the chimney.
Either the overflashings that are set into the chimney wall have developed cracks (or fallen out), or the apron and soaker tray flashings are starting to crack.
Over time, lead flashings will crack. This is due to stresses caused by heat from the sun – especially where the flashing has been stretched over an object initially.
The repair options are either to replace all the apron and soaker flashings with new lead or with the new ‘lead free’ flashings like “Wakaflex” – or to simply clean up the cracks and repair with roofing silicone.
Whilst the new flashing option is the proper ‘belt and braces’ solution, I sometimes find that a semi – permanent fix with the silicone will provide many years of service.
Which is the more appropriate option depends on the age of the roof and the owner’s situation.
The video below shows how to locate a leak at a chimney on an old terracotta tile roof:
Getting your inner west roofs replaced in Sydney needs innovative thinking
80 % of the roof repairs we do in the inner west are just like the rest of Sydney. Leaking skylights, rusty roofs, flashings and guttering plus a bit of bad workmanship by other roofers….
The other 20% makes us stop and think.
Because the logistics of the congested inner west forces new problems upon us. We need to re-engineer things to make our lives easier and still produce a result that performs well.
… Like what happened at the roof sheeting at the Erskineville roof job…
The delivery driver craned off the bundle of roof sheets onto the footpath… two blocks from the job site.
“Sorry guys… this the best I can do”
Two roofers can carry a 10.5m kliplok roof sheet over a short distance. But it takes 3 guys to struggle two street blocks with it.
It must have been a sight!
One roof sheet, 3 guys….weaving between the road and footpath. Then rinse and repeat 7 times.
We were so thankful that it was a narrow roof and only needed 7 sheets.
Maybe we should have done this!
For a bunch of reasons, we did not do this Erskineville roof replacement job with an engineered lap joint. But we have made our lives a lot easier on many other occasions in Sydney’s inner west with kliplok lap joints like that pictured above.
Doing a challenging leak repair at a vent pipe on a kliplok roof in inner west Sydney
There was this colorbond kliplok roof in the Inner Western Sydney suburb of Campsie that presented a real challenge to us….
When we investigate roof leaks, we go through a process of elimination.
On this particular roof, there was the obvious PVC vent pipe which was located above the leak.
Then there may have been a problem at the upstream end of the roof sheeting because either the flashing was leaking, the turn-up was inadequate, or there is debris causing overflowing…
So, we cleaned the old sealant off the dektite flashing around the PVC vent pipe and re-sealed it. When it rained again, the leak was still there!
Then we went back again to pull apart the upstream flashings. The upturns were not quite right (and we found that the blanket insulation was damp) – so we fixed these and cleared away the debris that had built up under the flashing. We waited again and the next report was that the roof leak was still there!
Capillary action lets water do amazing things. It is the only thing that can make water flow uphill!
So, in the design of metal roofing, great pains are made to combat the results of capillary action where the roof sheets overlap one another. The edge of the roof sheets are designed to prevent capillary action from drawing water over the lapped rib PLUS there is a catchment lip added on in some profiles to catch any water that manages to get over.
Kilplok roofing sheets rely mainly on grooves to prevent water climbing over the lapped rib.
Alarm bells sound when my guys see a vent pipe (or any roof penetration) cut into the area where two roofing sheets lap. This means that the catchment lip has been compromised and a leak could be happening…
Yet in this instance, the PVC vent pipe penetration hole was cut neatly beside the overlapped rib – so no potential problem there….
Finally, drastic action was needed. The roof sheeting had to come off!
It is quite easy for a screw fixed roof to take a roof sheet off . But a kliplok roof is a different matter. There are no screws. Extreme care has to be taken not to damage the roof sheeting because the concealed clips holds the roof on tightly. Usually, it is impossible to remove without causing some damage.
…Anyway, we managed to lift the lapping sheet up a bit to investigate what was happening.
What we found was that capillary action was up to her old tricks again. It was allowing water to seep along the lap – which allowed it to travel past (by going under) the dektite vent flashing seal!
It was another gem to put into our database of “why roofs leak”.
Check out the video below to see what happened…
Getting a tricky roof repair on a kliplok roof done in Sydney's inner west
We were called out to a terrace house in Sydney’s inner west to trace and repair a leak on a fairly new colorbond flat kliplok roof recently.
The story is fairly common. “Builder put up renovation with a new colorbond roof. Roof leak discovered a while after hand over. Only leaks during rains when it is windy. Builder tried to fix leak with no success….”
Sydney Roofers can hide many mistakes on a roof – but critical mistakes involving serviceability do not stay hidden for long. It can leak on a perfectly ‘good looking’ roof. Just because the mistakes are hidden under flashings does not mean that they are not found out..
Water leaks at a wall that the roof sheeting abuts onto, are usually either due to the flashings leaking, or something ‘funny’ hidden under the roof flashing.
In this case, the colorbond kiplok roof was quite well put together – but it had an annoying leak at the top corner – that had baffled many past roofers who were called in to do a roof repair.
After checking out the flashing and not finding any problems, it was time to do some ‘surgery” work on the flashings.
…and guess what we found underneath?

Getting a box gutter (due to premature rusting) replaced n Inner western Sydney
Sydney’s inner west have tighter building areas and inner west roofs tend to have an extreme mixture of elements that can cause quite unique roof leakage problems that require major roofing repairs. The mix of new and old materials introduces incompatibility and galvanic corrosion is common.
While box gutters are mainly used in the domain of commercial roofs, they are sometimes used on residential roofs. And because roofs in Sydney’s inner west demand a bit of innovation where there are space restrictions and architectural flair, box gutters are sometimes used. It is also an area in Sydney where the nice looking Velux skylights are often installed.
While a well designed box gutter will perform quite well, sometimes they are not put together correctly. And sometimes even if the installation is carried out correctly, someone does something afterwards that is somewhat troublesome. Like placing lead flashing on a zincalume box gutter.
Like this electrolysis problem with lead flashings from Velux skylights that I saw on a roof in Sydney’s inner west that will require a box gutter replacement way before it should be required…
The flashings used by the Velux skylight manufacturers are lead based. The Velux skylights are often installed on zincalume and colorbond metal roofs. Colorbond tends to have a much higher resistance to the ‘galvanic’ corrosion between the dissimilar metals. Zincalume on the other hand will corrode quite rapidly when damp conditions exist for long periods between the two metals.
So, it is very common on zincalume metal roofs to find rust problems when there is a Velux skylight involved. … Hope you enjoy the video below:
The lure of the doing roof repairs in Sydney’s inner west
Once upon a time, gypsies roamed the inner west. With the change in demographics, they now target the defenseless homeowners in the outer west.
If you don’t know what gypsies are, check out my blog article about a gypsy attack on a poor inner west home owner.
With a name “The Roofing Professionals Westside” – you would think that we must do a lot of roof repairs in the inner west.
And we do.
We like the inner west – because it is quite central to where we live and we like the challenges that the inner city suburbs pulls on us. So, despite all its challenges, we fix a lot of leaking roofs there.
Roof repairs in the inner west of Sydney is unlike anything else. That is why we keep coming back when we get asked….
