The north, council by council
City of Joondalup
Created on 1 July 1998 from Wanneroo's coastal areas, its 22 suburbs include Hillarys, Sorrento, Duncraig, Mullaloo, Ocean Reef, Kingsley and Joondalup itself. Major growth came in the 1980s and 1990s, and 88.6% of occupied homes were separate houses in 2021.
City of Wanneroo
Wanneroo added almost 110,000 people between the 2001 and 2016 censuses and had 209,111 by 2021. Its main centres are Wanneroo and Clarkson, with Alkimos, Yanchep and Two Rocks named as future urban centres. 92.1% of occupied homes were separate houses, and the median age was 35.
The 2010 hail
On 22 March 2010, hail of 4 to 6 cm fell in a strip from the northern coastal suburbs to south Perth. About 15 schools in the northern suburbs closed, and FESA and the SES received more than 3000 requests for help.
Ocean on the west
The City of Joondalup is bounded by the Indian Ocean, so its beachside suburbs need roofing products chosen with salt in mind.
Which part of the north are you in?
| Older Joondalup council suburbs | Newer Wanneroo estates | |
|---|---|---|
| When most homes went up | Mainly the 1980s and 1990s | Much of it since 2001 |
| Jobs to expect | Ridge mortar, tired coatings, gutters, older fixings | Build details, solar and air conditioner penetrations, first gutter clogs |
| Who to ring first | A roofer | Your builder, if the home may still be under warranty |
| Extra check | Salt exposure in the coastal suburbs | The builder's paperwork and roof specifications |
Which jobs match which part of the north?
In the established Joondalup council suburbs, roofs from the 1980s and 1990s are now thirty to forty-odd years old. That's the age when ridge mortar, coatings and gutters deserve a proper look, and when rebedding and repointing or a roof restoration comes up.
On the coastal strip, salt is the extra factor. BlueScope sets minimum distances from breaking surf for its roofing products, so the right choice a block from the beach may not be the one you'd pick five kilometres inland. Colorbond roofing in Perth goes into the options.
In the newer Wanneroo estates, problems are more likely to be workmanship details on a young roof, or damage from later work such as solar panels going on. Talk to your builder about the warranty before paying for repairs on a recent home.
Our suggestion for the north
Work out which group your home falls into first. For an older place near the coast, we'd have a roofer check the ridge, fixings and gutters, and name the product grade for any metal work. For a newer estate home with a problem, we'd go to the builder with photos before anyone else.
