Valleys, box gutters and sumps carry concentrated water and fail inward rather than over the edge. On Martin properties that means a leak appears well inside the building, frequently a long way from the fault.
Roof Plumbing in Martin: the short version
A bead of sealant is not a flashing. It works for a season, then cracks and traps water behind it. More on our roof plumbing page.
Why Martin roofs behave the way they do
Martin is rural and semi-rural country in the foothills of the Darling Scarp rather than a suburb of streets. That changes the whole shape of an inspection: here the property is the job, not just the house. Expect septic or aerobic treatment systems, bore or tank water, dams, long private driveways and substantial outbuildings, sheds, stables, machinery storage, that are frequently owner-built, unengineered and sometimes never approved. Those structures need assessing explicitly or excluding explicitly, because a buyer who assumes a large shed comes with the land in sound condition can inherit a significant cost. The ground is the second defining factor. Worth knowing. At the foot of the scarp, the material underfoot shifts over short distances between coastal-plain soils and foothill granite and laterite. That makes differential founding, part of a structure bearing on solid rock, part on soil or fill, a realistic cause of cracking that has nothing to do with the quality of the building. It means excavation costs for any future work vary enormously from one property to the next. Tributaries of the Canning system cross the district, so low ground near watercourses carries a seasonally high water table, winter wet. Overland flow, while land on the rising side brings slope, retaining and cut-and-fill instead. With bushland and state forest on the scarp side, bushfire exposure is genuine and termite pressure high. The practical realities of distance apply too, with slower emergency response and real difficulty getting trades to attend for small jobs.What that means for roof plumbing in Martin
Fixings deserve as much attention as the sheet. A premium flashing fastened with inadequate screws fails at the screws and that is where cheap coastal work cuts corners invisibly.
Constant leaf drop from mature canopy packs into valleys and box gutters in these streets and organic matter held against metal keeps it wet continuously.
On low ground the drainage question extends past the roof. Downpipes discharging onto saturated soil have nowhere to go, so what the roof plumbing delivers has to be dealt with at ground level too.
Martin roofs: symptom and fix
| What you are seeing | What it usually means | What it needs |
|---|---|---|
| Damp high on an internal wall | Apron or step flashing failed | Cut out and re-flash |
| Stain on a chimney breast | No back gutter, or it has corroded | Install or renew the saddle |
| Steady drip in ordinary rain | Valley perforated under the tiles | Replace the valley run |
| Leak beside a skylight | Perimeter flashing kit failed | Re-detail the surround |
Guide only. Every roof differs, which is why we look before quoting.

Roof Repairs in Martin
Learn moreMost Martin 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 Huntingdale. 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.

Roof Restoration in Martin
Learn moreA roof restoration renews a tired but sound Martin 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 Southern River. 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 Martin 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 Martin
Learn moreWhen a Martin 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 Gosnells, 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 Martin

Roof Inspection in Martin
Learn moreA roof inspection is the cheapest way to know exactly what your Martin 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 Orange Grove, 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 Martin

Roof Carpentry in Martin
Learn moreRoof carpentry is the structural timber under your tiles — the rafters, battens and trusses that hold everything up. On Martin 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 Maddington 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 Martin

Roof Cleaning in Martin
Learn moreRoof cleaning strips the moss, lichen and black weathering off a Martin 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 Huntingdale. 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 Martin 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 Martin roof metalwork needs attention
- A leak that started after solar panels went on
- Bubbling paint or render below a roof junction
- Water inside a building with no overflow visible outside
- Damp high on an internal wall rather than mid-ceiling
- Staining on a chimney breast or beside a skylight

Recent work


What the work involves
- 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
- Match the metal to what it touches. Grade suited to the exposure and never dissimilar metals in contact where moisture will sit between them
Common questions about roof plumbing in Martin
Do you work on commercial buildings?
Yes. Box gutters, sumps, parapet detailing and internal drainage on strata and commercial stock, documented with photographs so an owners corporation can act on it.
Can you match old lead flashings?
Lead appears on many older Perth homes and shapes beautifully around awkward brickwork. It should not be drained onto modern coated steel, though, because the two corrode at the join.
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.
Do you work throughout Martin?
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.
