Roof repairs and roof replacement in Allambie Heights

The bushland around Manly Dam fills most of Allambie Heights, and the suburb’s houses ring its edge. For roof repairs, a full roof replacement or new gutters and gutter guard in Allambie Heights, tell Roofing Northern Beaches about the roof, and a licensed local roofer who covers the suburb can call you to talk it through.

In the 2021 Census, 2,034 of Allambie Heights’ 2,339 occupied private dwellings (87.0%) were separate houses and 49.1% had four or more bedrooms, so most roofs here are the owner’s to arrange rather than an owners corporation’s. The Dictionary of Sydney says the suburb’s name means “a peaceful place” and that it “developed after the Second World War when returned soldiers sought land for building homes”.

Re-roofing beside Manly Dam’s heritage-listed bushland

About 65% of Allambie Heights is public recreation land, almost all of it the Manly Warringah War Memorial Park around Manly Dam, by our calculation from NSW Government map data. The park was added to the State Heritage Register on 13 January 2023, and most of it is also the Warringah LEP’s “Manly Dam and Surrounds” heritage conservation area, a landscape area rather than a group of houses.

The Codes SEPP’s exempt like-for-like re-roofing isn’t available “in a heritage conservation area”. By our calculation only a sliver of residential land on the reserve edge, about 0.3% of it, falls inside that area, and the map can’t tell us which lots. If your home backs onto the reserve, check council’s map or your section 10.7 planning certificate before planning a re-roof. By our map reading, no house in Allambie Heights is itself a listed heritage item.

Allambie Heights is in the former Warringah council area, so the Warringah LEP 2011 and DCP 2011 apply until the new Northern Beaches plans, exhibited from 20 July 2026, commence; council expects that in mid-2027. Where roof work needs a development application, the DCP says buildings close to bushland “must blend in to the natural landscape” and suggests “medium to dark roof tones”. The guide to council approval for a new roof covers when an application is needed.

Bush fire prone land along Manly Dam and Allenby Park

About 76% of Allambie Heights is mapped bush fire prone, by our calculation from NSW Government map data, and so is about 34% of its residential land, mostly the buffer beside the Manly Dam and Allenby Park bushland. The Northern Beaches Bush Fire Risk Management Plan, commencing 2025, names Allambie Heights as one of nine focus areas. It warns of the potential “for rapid impact upon nearby assets” in periods of elevated fire danger and says a high number of homes in the area are in its High Risk category. On 30 November 2025 a fire near Manly Dam prompted a Watch and Act alert for properties around Southern Cross Way, the Manly Observer reported.

On mapped land, an exempt re-roof must “be adequately sealed or protected to prevent the entry of embers” and “use equivalent or improved quality materials”, under the Codes SEPP. The BAL roofing requirements tool explains what each bush fire attack level asks of a roof.

Gutters and sloping blocks in Allambie Heights

Before a planned hazard reduction burn at Allenby Park in September 2024, Fire and Rescue NSW’s advice to neighbours, as reported by the Manly Observer, included “Clear gutters of leaf debris.” The NSW RFS adds that gutter and valley leaf guards “should be non-combustible and provided and installed in accordance with AS3959”. Gutters and gutter guard covers the options.

About half of Allambie Heights’ residential land is on what the Warringah LEP maps as landslip risk Area B, flanking slopes of 5 to 25 degrees, by our calculation. Those controls apply to development applications, and a like-for-like re-roof isn’t normally one.

Before re-roofing in Allambie Heights

Whether a new roof needs approval depends on the property, not just the suburb: whether it’s a heritage item or in a heritage conservation area, whether it’s on bush fire prone land, and whether the old roof contains asbestos. Your property’s planning certificate shows its heritage and bush fire status, and Northern Beaches Council explains exempt and complying development. The roofer should confirm the approval pathway with the quote. See roof replacement for the conditions.
