Sydney Roof Repairs: What to Check
3 November 2026 · 4 min read · How-To Guides
Quick answer
To get a roof repaired in Sydney, ask for a written quote after an inspection, check the roofer's licence on Service NSW if the job is residential building work over $5,000, and make sure larger jobs have a written contract. Ask about safety equipment for working at height. Treat old fibro or cement sheeting with care because it may contain asbestos.
Sydney roofs face summer storms, hail, strong winds and salt air near the coast. Terracotta tiles crack, ridge capping mortar crumbles, and older metal roofs rust around fixings. A small leak in a February storm can soak ceilings and insulation quickly. This guide explains how to find a roofer in Sydney, what NSW rules say about licences and contracts, and how to avoid storm-season traps.
Does a Sydney roofer need a licence?
In Sydney, residential building work worth more than $5,000 including labour and materials must be done by a business with an NSW contractor licence, and needs a written contract. Smaller repairs may not need one, but a licence is still a good sign. Cottlink suggests checking the licence online before you agree to any roofing quote.
Use the Service NSW licence check to confirm the business name, licence class and status. Cottlink's Sydney tradie licence check guide walks you through the search step by step.
What should a Sydney roof repair quote include?
A Sydney roof repair quote should describe the problem found, the materials such as matching tiles or new metal sheets, rebedding and repointing of ridge caps, flashings, safety rails or scaffolding, waste removal, GST, timeframes and any warranty on workmanship. Cottlink recommends asking for photos taken on the roof so you can see what needs fixing.
- Cause: cracked tiles, failed ridge mortar, rusted sheets or blocked valleys.
- Materials: matching tiles, Colorbond-style sheets or flashings.
- Safety: edge protection or scaffolding needed for the height.
- Extras: gutter and downpipe repairs or replacements.
- Warranty: how long the workmanship is covered.
What NSW rules apply to bigger roofing jobs in Sydney?
For larger Sydney roofing jobs, NSW law requires a written contract for residential work over $5,000, and home building compensation cover for residential work over $20,000. The contract should show the licence number, price and scope. Cottlink advises reading NSW Fair Trading guidance before you sign or pay a deposit for a new roof.
NSW Fair Trading's building and renovating pages explain contracts, deposits, insurance and what to do if something goes wrong.
Could my Sydney roof contain asbestos?
Older Sydney homes, particularly those built before the late 1980s, may have roofs, eaves or sheds made of fibro or corrugated cement sheeting containing asbestos. Do not cut, drill or pressure-clean it. Ask roofers whether they are licensed for asbestos removal or will arrange a licensed removalist before the work begins. Read this Cottlink guide before you book.
After a storm
When a storm damages your roof, make the home safe first. Keep clear of fallen power lines and sagging ceilings, and call the SES on 132 500 for emergency help with storm damage if needed. Take photos for your insurer and contact them early, because many policies want to approve repairs. Be cautious of anyone door-knocking after a storm with cash offers to fix your roof today.
Gutters, valleys and leaf guards
Leaves from gum trees and jacarandas block gutters and roof valleys, sending water back under tiles. Clear gutters before summer storm season and before bushfire season, because dry leaves in gutters are a fire risk. Leaf guards can help in leafy suburbs. Ask whether the roofer also checks downpipes and stormwater connections when they clean gutters.
Tiles versus metal
Many Sydney homeowners replacing a tired tiled roof weigh up new tiles against a metal roof. Metal is lighter and can suit solar panels, while tiles may match the street's character. Heritage areas may have rules on materials, so check with your council. If you plan to add air conditioning or solar at the same time, coordinate trades so roof penetrations are sealed properly; Cottlink's air conditioning installer guide covers that side.
Roof restoration versus repair
Many Sydney roofers offer full restorations: cleaning, replacing broken tiles, rebedding and repointing ridge caps, and applying a coating. A restoration can extend the life of a sound roof, but it is not always the right answer. If tiles are porous throughout or a metal roof is rusted through, replacement may be better value over time. Ask each roofer to explain why they recommend one option, what the coating actually does and how long they expect the work to last. Be cautious of a quote that pushes a restoration on a roof that only needs a few tiles replaced.
Check the warranty in writing. A workmanship warranty from the roofer is separate from any product warranty from the coating or tile maker, and each has its own conditions. Keep the paperwork with your home records, as it can help when you sell.
