Slate Roof Replacement and Re-slating in Adelaide

What slate roof replacement and re-slating in Adelaide actually involves

A US National Park Service brief on historic slate roofs (guidance for American buildings, not an Australian rule) says: If 20% or more of the slates on a roof or roof slope are broken, cracked, missing, or sliding out of position, it is usually less expensive to replace the roof than to execute individual repairs.

What a replacement quote should say

The State's guide to State Heritage Places lists re-roofing, and replacing gutters or downpipes among the types of work that typically need development approval at a State Heritage Place or State Heritage Area. It adds that if you are unsure what needs approval it is recommended that you contact your Local Council planning officer. It is about State Heritage Places, not local heritage places.

Ask the provider whether the quote reuses the existing slates and how many new ones it assumes, and who deals with the council if the house is a heritage place.
