Half the roof leaks we trace end at a plumbing detail — a rusted valley, a tired flashing, a box gutter nobody has looked at since the extension went on. Roof plumbing is the trade that manages water on and off your roof, and it is core work for our licensed Sydney crews: diagnosed with photos, quoted fixed and in writing.
Roof plumbing is the trade that manages water on and off your roof: gutters, downpipes, box gutters, valley irons, flashings, rainheads and overflows. When a roof leak turns out to be a rusted valley, an under-sized downpipe or a flashing that was never lapped properly, it is roof plumbing work — and it is a large share of what we do every week across Sydney.
Gutter and downpipe work — repairs, re-sloping, full gutter and fascia replacement in Colorbond, extra downpipes for under-drained roofs, and leaf guard for tree-lined blocks. Valley iron replacement — one of the most common leak sources in Sydney; we lift the surrounding tiles, fit new steel and re-lay. Flashings — wall aprons, chimneys, skylights and penetrations, stepped and lapped the way they should have been the first time. Box gutters and rainheads — the high-consequence details on extensions and older homes, where an overflow ends up inside the wall. Leak diagnosis — because half the roof leaks we trace with our leak detection service end at a plumbing detail, not a tile.
Honestly: you usually do not have to decide — you need the problem fixed, and we hold the licence and do both. If water appears near an external wall, after heavy rain, or where two roof planes meet, it is likely roof plumbing. Ceiling stains mid-room point at the roof surface. Either way the free inspection covers the whole system — roof, valleys, flashings, gutters and downpipes — and the photo report shows you exactly which one is the culprit.
Extensions that doubled the roof area without adding a downpipe. Box gutters hidden behind parapets and forgotten for twenty years. Lead flashings against modern Colorbond (they react). Gutters re-sloped by eye instead of a level. We see the same handful of faults over and over — all fixable, all cheaper to fix before the next east-coast low.
Yes — gutters, downpipes, box gutters, valley irons, flashings, rainheads and overflow provisions across greater Sydney. It is a core part of our repair work, licensed and insured.
You do not need to pick — we do both under the one licence. Water near external walls or roof junctions usually means plumbing details; mid-ceiling stains point at the roof surface. Our free inspection checks the entire system and the photo report shows the actual cause.
Gutter repairs typically run $300–$1,200, valley iron replacement and flashing work is quoted per job after inspection, and full gutter and fascia replacements are priced per metre on site. Every quote is fixed and in writing.
Yes — box gutters are high-consequence roof plumbing. We check capacity, fall and outlets, not just blockages, because an overflowing box gutter usually has a design problem behind it.
