Northcote is Edwardian and Californian bungalows with original terracotta, now renovated with metal-roofed rear extensions that create tricky mixed rooflines and valleys. FreshDuct cleans the lot, with photo proof.
Moss on the old terracotta and leaves in the new valley? A Northcote reno roof needs both cleared.
Northcote is one of the inner north’s most sought-after suburbs — Edwardian villas and rows of Californian bungalows climbing the hill along High Street, heavily gentrified and, over the last couple of decades, extensively renovated. The front of a typical Northcote home still wears its original terracotta tile, but out the back, architect-designed extensions have added flat and skillion metal roofs. The result is a lot of mixed-material rooflines where century-old terracotta meets brand-new Colorbond, joined by valleys and flashings that did not exist when the house was built.
Those junctions are where the trouble concentrates. A new valley or box gutter formed where an old tiled roof meets a modern metal extension is a natural trap for the leaf litter Northcote’s tree-lined streets drop, and if it blocks, water backs up at exactly the point two roof systems meet — a common source of leaks in renovated homes. Meanwhile the original terracotta on the shaded, hilly aspect grows moss and lichen as it always has, and the flat metal extension roofs collect debris and streaking of their own. It is a roof that needs cleaning as two connected systems, not one.
FreshDuct cleans these mixed rooflines with an eye to how they go together. We soft-wash the original terracotta at a pressure its age can take, clean the metal extension roofs the right way, and pay particular attention to the valleys, flashings and box gutters where old meets new — clearing the leaf litter that collects there and checking those vulnerable junctions. We treat the tile to slow moss regrowth and finish with before and after photos of a roof that, on a renovated Northcote home, is more complicated than it looks from the street.
The things we look at first on a Northcote roof — based on the local homes, roof types and conditions.
Northcote renovations join original terracotta to new metal extensions, creating valleys and box gutters that trap leaves and leak if they block. We clear and check these junctions as the priority.
The street-front terracotta on Northcote’s Edwardian and bungalow homes is century-old and brittle. We soft-wash at low pressure to lift moss and lichen without cracking it.
Modern rear extensions add flat and skillion metal roofs that collect leaf litter and streaking. We clean them the right way for coated steel and clear the debris they gather.

The classic Northcote renovation — a period terracotta home with a sleek metal-roofed extension out the back — looks great, but the valley where the two roofs meet is a genuine weak point. Choked with leaves it backs water up at the junction, and that is where renovated homes tend to leak.
We clean the terracotta and the metal as the connected systems they are, clear and check the valleys, flashings and box gutters where old meets new, and treat the tile against moss — then hand over before and after photos of a roof more complex than its street front suggests.
FreshDuct cleans roofs across Northcote and the inner north 7 days a week, including renovated period homes. We regularly work neighbouring Fitzroy, Brunswick, Collingwood and Abbotsford, so Northcote is a core part of our territory.
From the bungalows climbing the High Street hill to the renovated homes toward the Merri Creek, we can usually offer a prompt appointment and prioritise roofs where a blocked old-meets-new valley is threatening to leak.

Yes, that is a very common Northcote problem. Where an original terracotta roof joins a modern metal extension, a new valley or box gutter forms, and when leaf litter blocks it water backs up right at the junction and finds its way in. We clear and check those valleys and flashings, clean both roof surfaces, and that usually resolves the leak.
Yes, and we treat them as one connected system. The century-old terracotta gets a low-pressure soft-wash so the moss lifts without cracking it, the modern metal extension is cleaned the right way for coated steel, and we give particular attention to the valleys and flashings where the two meet — the part most likely to cause trouble.

It depends on the size and pitch of the roof, the roof material and how much moss and lichen has built up — a straightforward soft-wash is quick and affordable, while a heavily overgrown or steep roof is quoted separately. You get clear pricing up front before any work starts. Call 04 3191 8137.
Not the way we do it. For most tiled and older roofs we use a low-pressure soft-wash that lifts moss and grime without cracking tiles or stripping the surface, and we only use higher pressure where the material can safely take it. Matching the method to the roof is the whole point.
