Roof plumbing is the metalwork that makes a roof watertight where the covering alone cannot: flashings at every junction, valleys, box gutters, downpipes and every penetration. On Connolly homes that is where most leaks originate rather than in the tiles.
Why Connolly roofs behave the way they do
Connolly was built in the late 1980s as a golf-course estate, wrapped around the Joondalup Resort course. That origin shapes the suburb into two tiers: the homes that back onto the fairways are generally larger and more expensive, while the homes on the edges are smaller. Knowing which you are buying matters, because the premium golf-frontage houses tend to come with pools, extensive landscaping and additions, more building to inspect and more places for water and movement to hide. Backing onto a golf course carries a few specific things worth checking. Course irrigation runs constantly through summer, which can raise the local water table and keep the ground near boundary footings damper than it should be. There can be chemical run-off from course maintenance and a history of ball strike on fairway-facing glazing and roofs. None are dealbreakers, but they are the kind of thing a Connolly inspection should have in mind that a standard suburban one would not. The stock is late-1980s to 1990s brick-and-tile, now thirty to forty years old and into its first serious maintenance cycle, roofs, wiring and wet areas coming due together. Nothing dramatic. And Connolly is inland, backing onto the freeway rather than the coast, so the salt-driven concerns that dominate the beachfront suburbs, delignification chief among them, are a lower priority here.Roof Plumbing in Connolly: the short version
Dissimilar metals in contact with moisture corrode at the join far faster than either would alone, which is a common fault on well meant previous repairs. Background on our service page.
What that means for roof plumbing in Connolly
Rinsing sheltered metalwork occasionally does genuine good in these suburbs, because rain washes the exposed faces and misses everything beneath eaves and behind downpipes.
Soakwells on these blocks frequently cannot accept water during a wet winter, which turns a functioning roof drainage system into standing water beside the house.
On newer homes a metalwork leak is almost always a detailing fault rather than wear and it may sit under a builder's warranty rather than being your cost.
Connolly roofs: symptom and fix
| What you are seeing | What it usually means | What it needs |
|---|---|---|
| Leak beside a skylight | Perimeter flashing kit failed | Re-detail the surround |
| Water inside after heavy rain only | Box gutter or sump at capacity | Clear, then review capacity |
| Leak dating from a solar install | Penetration never detailed properly | Re-detail the mounting points |
| Corrosion where two metals meet | Galvanic reaction at the join | Replace in one consistent material |
Guide only. Every roof differs, which is why we look before quoting.

Roof Repairs in Connolly
Learn moreMost Connolly roof problems come down to a handful of failures: cracked or slipped tiles, perished ridge pointing, rusted valley irons and tired flashings. We trace the leak to its actual source — which is rarely under the ceiling stain — and fix the cause, whether that’s replacing matching tiles, re-bedding and re-pointing the ridge in a flexible compound, or renewing a corroded valley.
We’ll always tell you honestly when a roof is genuinely repairable versus when the repairs are mounting up and a restoration would serve you better, as it often does through nearby Edgewater. Prompt repair matters: a single cracked tile left through a wet winter becomes soaked insulation, stained ceilings and, eventually, damaged roof timber. Every repair is backed by our workmanship warranty, and because we photograph what we find and talk you through it, you’ll understand exactly what was wrong and what we did about it rather than being handed a bill and a shrug.

02Roof Restoration in Connolly

Roof Restoration in Connolly
Learn moreA roof restoration renews a tired but sound Connolly roof for a fraction of replacement: we treat the moss and lichen, high-pressure clean, replace broken tiles, re-bed and re-point the ridge caps in a flexible compound, then seal and coat with a Dulux AcraTex membrane as accredited applicators.
It’s the right call when the tiles have decades left but the surface and pointing are gone — the same judgement we bring to nearby Mullaloo. We’ll tell you honestly whether a restoration suits your roof or whether repairs or a re-roof make more sense, and the finished job carries both a manufacturer coating warranty and our 10-year workmanship warranty. Most Connolly homes take two to three days depending on the repairs needed before coating. As accredited applicators we prepare to the manufacturer’s specification, so the membrane actually holds — a coating only lasts if the surface beneath it was treated, cleaned and repaired properly first, which is exactly where a cheap spray-over fails within a couple of summers.

Roof Replacement in Connolly
Learn moreWhen a Connolly roof reaches the end of its life — porous tiles, rusted-through valleys, or a roof that’s been patched one too many times — a full re-roof is often the honest answer. We strip the old covering, check and repair the timber and battens underneath, and install a new tile or Colorbond roof with fresh sarking, valleys and flashings throughout.
A tile-to-Colorbond conversion is popular here for its lighter weight, clean lines and colour range, and because the lighter roof changes the wind uplift we reassess the tie-down as part of every conversion. We’ll also be straight about whether you’ve genuinely reached replacement or whether a restoration, as we do through nearby Heathridge, would renew the roof for a fraction of the cost. Every re-roof is engineered and tied down to Australian Standards and backed by our 10-year workmanship warranty, and we handle the guttering, flashings and tie-down as one job so nothing is left for you to chase afterwards.

04Roof Inspection in Connolly

Roof Inspection in Connolly
Learn moreA roof inspection is the cheapest way to know exactly what your Connolly roof needs before you commit to anything — or before you buy. We get onto the roof and into the roof space, physically checking the tiles, pointing, valleys, flashings, gutters and the structural timber, then hand back a clear written report with photographs.
On older homes we test the timber for rot, termite damage and delignification; on newer ones we look for the builder-grade detailing faults that leak early. It’s the same thorough check we run through nearby Joondalup, and it’s what tells you whether a roof needs a minor repair, a restoration or something structural. If you’re buying a home, an inspection of the one part most people skip — the roof space — is money very well spent, and the written report gives you something concrete to put in front of an agent, a buyer or your insurer rather than a verbal all-clear.

05Roof Carpentry in Connolly

Roof Carpentry in Connolly
Learn moreRoof carpentry is the structural timber under your tiles — the rafters, battens and trusses that hold everything up. On Connolly homes we repair and rebuild that framing to standard: sistering weakened members, replacing rotted or termite-damaged timber, and reinstating trusses that have been cut for a skylight, duct or downlight.
We also test for delignification, the chemical breakdown that leaves roof timber looking sound but unable to hold a fixing — the same treatment we carry out through nearby Beldon where the timber is worth saving rather than replacing. As registered builders we can certify structural carpentry, which a general handyman can’t, and we assess the whole load path while we’re in the roof space so a repair addresses the cause, not just the symptom. Where a member is load-bearing we prop it safely with acrow props and work to a structural engineer’s design before anything is cut — it’s the natural companion to our tie-down and structural-defect work.

06Roof Cleaning in Connolly

Roof Cleaning in Connolly
Learn moreRoof cleaning strips the moss, lichen and black weathering off a Connolly roof and gets it back to a clean, even surface — either as a standalone tidy-up or as the first stage of a restoration. We treat the growth first so it dies at the root, then clean at a pressure matched to the tile so we lift the grime without stripping the surface or driving water under the laps.
Left alone, that growth holds moisture against the tiles and works into the pointing, which is why we treat rather than just blast it — the same method we use through nearby Edgewater. We check the roof over while we’re up there and flag anything that needs attention, so a clean doesn’t paper over a repair that’s quietly getting worse. On steeper or two-storey Connolly roofs we work off proper anchorage and stay off the tiles where we can, so the clean lifts the grime without cracking the very surface it’s meant to protect, and we’ll let you know if the roof would be better served by a full restoration.

Signs Connolly roof metalwork needs attention
- Damp high on an internal wall rather than mid-ceiling
- Staining on a chimney breast or beside a skylight
- Water appearing only in wind-driven rain
- Rust streaks running out of a valley into the gutter
- A leak that started after solar panels went on
Local conditions in Connolly
Built as a late-1980s golf-course estate, homes back onto fairways. Golf-course-margin issues: irrigation over-spray/water table, chemical run-off, netting/ball-strike history and premium builds with pools/extensive landscaping.
Late-1980s-90s brick-and-tile, now 30-40 years, first major maintenance cycle.
Inland (no ocean frontage), salt/delignification lower priority.
We cover the whole of the City of Joondalup. Around Connolly that takes in Joondalup and Marmion. Short drives keep roof plumbing affordable on smaller jobs and most of ours are smaller jobs.
Materials and specification
On box gutters, capacity is calculated rather than estimated. Roof area, rainfall intensity, sump size and overflow provision are related by design and an installation that has worked for years can still be under capacity for the heaviest half hour of the year.
A little about Connolly
Shenton Ave (N), Mitchell Freeway (E), Hodges Dr (S), Marmion Ave (W) After John Connolly, private in the 63rd Regiment, held land here 1838; arrived 1829 Homes bordering the golf course generally larger and more affluent; edge homes smaller; late-80s-90s None of that decides what your roof needs. It does tell us what to expect before we get the ladder out in Connolly.
Recent work


What the work involves
- Trace the water before touching anything. Metalwork leaks enter well inside the roof and travel along framing before they drop, so the stain is almost never under the fault
- Remove the old detail rather than covering it. Failed flashings come out so the timber and masonry behind can be seen. Roof cement over a failing junction hides the deterioration while it continues
- Fabricate and lap it correctly. Metal shaped to the actual junction rather than forced into shape, lapped so water runs over each joint instead of into it, mechanically fixed with sealant as a secondary defence rather than the primary one
Common questions about roof plumbing in Connolly
What is roof plumbing exactly?
The metalwork on a roof: flashings, valleys, box gutters, downpipes, sumps, rainheads and the detailing around every penetration. It is a distinct trade to tiling and it accounts for most leaks.
Why does my chimney leak when the roof is fine?
A chimney is a masonry column punched through a waterproof surface and water runs downhill into its uphill face. That side needs a back gutter or saddle to divert water around it. Many older Perth homes never had one, or it has corroded away.
Can flashings be repaired or do they need replacing?
Occasionally repaired where the metal is sound and only the termination has failed. More often replacement is honest, because half the cost is access and doing it twice wastes both.
Why did my leak start after solar was installed?
Mounting feet penetrate the roof covering and they are installed by electricians rather than roofers. Good installers detail them properly. Not every installer is good and it is the most common new-leak cause we attend.
Do you work throughout Connolly?
Yes and the surrounding suburbs. Ring 0421 768 842 and tell us your street. If we are not the right people for the job we will say so rather than quoting anyway.
Three questions worth asking first
Ask what was actually inspected. A quote produced from the footpath, a photograph or satellite imagery is a guess, because mortar condition, valley corrosion and batten integrity determine most of the work and none can be assessed remotely. On a Connolly roof that difference regularly amounts to thousands.
