Australian standards and Code requirements we work to, with the source for each.
AS 2050, the installation standard for concrete and terracotta roof tiles, applies to roofs pitched at 15 degrees or more. Below that the tile system falls outside the standard and a sheet metal profile is the compliant answer, not more bedding and pointing.
Any tiled roof pitched at less than 18 degrees has to have sarking underneath it, whatever the rafter or truss length. On older Sydney houses re-roofed before that rule bit, this is a common reason a tiled roof leaks in wind-driven rain.
AS 2050 governs how ridge and hip capping is bedded and pointed. Flexible pointing compound is what holds the capping as the roof moves; when it cracks and lets go, the capping lifts in wind and water tracks straight into the roof space.

Roof repointing in the Eastern Suburbs has its own rules: heritage areas, salt air and tight access all change how the job is done. Everything below links to the council or standard it comes from, so you can check it yourself.
In Paddington skylights are not allowed on the front or side roof planes, any skylight on the main roof is capped at 1.5 square metres, and rear planes are limited to 25 per cent transparent material.

Between 100m and 200m an AZ200 or AM150 coating is required, and only past 1km does the standard category apply. That changes fixings, flashings, gutters and downpipes.

The dominant trees there are Norfolk Island pine, coastal banksia, melaleuca and bottlebrush, which pack a gutter gradually instead of blocking it in one drop.

Roofs in the Eastern Suburbs corrode faster because many streets sit close to breaking surf, and salt attacks steel sheeting, fixings, flashings and gutters. The National Construction Code puts a home within 100m of breaking surf in the harshest corrosion category, requires an AZ200 or AM150 coating between 100m and 200m, and only applies the standard category beyond 1km.
Twice a year suits most Eastern Suburbs homes, with a shorter cycle under coastal trees. Waverley’s frontline coastal zone, from the Dover Heights and Vaucluse cliff tops to Clovelly, is planted with Norfolk Island pine, coastal banksia, melaleuca and bottlebrush, which pack a gutter gradually all year instead of blocking it in one drop.
Most established trees in Randwick and Woollahra need council approval before pruning, and leaf drop into gutters is not generally a reason to remove…
