The whole timeline, not just the roof days
Sydney Roofs Repair arranges roof replacements across metropolitan Sydney through independent local roofing contractors. When owners ask how long a re-roof takes, they usually mean the days of noise and scaffolding. Those days matter, but the whole project runs from the first inspection to the final handover. This guide walks through each stage and what affects it. All timings vary; treat them as a guide.
Stage 1: Inspection and quote
The contractor inspects the roof, measures it, looks in the roof space and notes anything unusual, such as asbestos, heritage controls, solar panels or difficult access. A written quote follows. Getting two or three quotes is sensible and adds some time, but it is time well spent.
Stage 2: Decisions
Choosing the material, profile, colour and extras such as gutters, insulation and skylights. Owners who decide quickly keep the project moving. If you are unsure, look at the colour on real roofs in your area.
Stage 3: Approvals and permits
Many like-for-like re-roofs need no planning approval, but heritage properties, structural changes and some other situations do. Footpath, scaffold and skip bin permits may also be needed. These can range from quick to lengthy. See our permits guide.
Stage 4: Scheduling and materials
Contractors schedule jobs weeks ahead in busy periods, especially after major storms. Common materials are usually available quickly; special colours, profiles, slate or particular tiles can take longer.
Stage 5: Site set-up
Scaffold or edge protection goes up, skip bins arrive, and solar panels, antennas or air-conditioning units are removed if needed. This often happens the day before or the morning the roof work starts.
Stage 6: Asbestos removal, if needed
For asbestos cement roofs, a licensed removalist removes the sheets under SafeWork NSW rules before the roofer starts. This includes wetting, removal, wrapping, disposal and, where required, a clearance inspection. It is a separate stage with its own timing.
Stage 7: Strip and inspect
The old roof comes off in sections. Crews generally open only what they can cover again by the end of the day. Once the old covering is off, battens and trusses are inspected and any rotten or damaged timber is replaced. Hidden damage can add time here.
Stage 8: New roof
Sarking or an insulated blanket goes on, then the new covering. Steel goes on faster because sheets are long and fixed in rows. Tiles are laid individually, and ridges and hips are bedded and pointed or fixed with a dry system. Flashings, valleys and penetrations are completed.
Stage 9: Gutters and finishing
New gutters, downpipes and fascia covers are fitted if included. Solar panels and other equipment are reinstalled by the appropriate trades.
Stage 10: Clean-up and handover
The site is cleaned, waste removed, and gutters checked for debris and swarf. You receive warranties, product details and any compliance documents.
What stretches the timeline
- Weather. Rain stops roof work and can add days, particularly during wet spells.
- Two storeys and steep pitches. More scaffold and slower, more careful work.
- Complex roofs. Many hips, valleys, dormers and penetrations.
- Access. Terraces, steep blocks and narrow streets.
- Hidden damage. Rotten battens or trusses.
- Asbestos. An extra stage before the new roof.
- Heritage requirements. Specialist materials and methods.
- Other trades. Solar installers and electricians must fit in.
Steel versus tile timing
Steel is typically faster on site than tiles for a similar roof, because sheets cover a large area quickly and there are no ridges to bed and point. Tile-to-steel conversions can be quick once the tiles are down. Tile-to-tile and slate jobs take longer.
Living at home during the work
Most families stay at home. Expect noise from early morning, trades around the house and some dust in the roof space. Keep children and pets clear of the work area. Our residential roof replacement page has practical tips.
Sample timeline for a straightforward job
This illustration shows how a simple tile-to-steel re-roof on a single-storey Sydney house might unfold. Real jobs vary.
| Phase | What happens | Rough duration (guide only) |
|---|---|---|
| Inspection and quotes | Contractors inspect and send written quotes | A week or two |
| Decisions and contract | Choose colour and extras, sign the contract | Days to a couple of weeks |
| Approvals | Often none for like-for-like work | Nil to several weeks |
| Waiting for a start date | Depends on demand and season | A few weeks is common |
| On site | Set-up, strip, timber repairs, new roof, gutters | A handful of working days |
| Handover | Clean-up and documents | A day |
Add time for asbestos removal, heritage approvals, special materials, two storeys or a run of wet weather.
Questions to ask about timing
- When could you start, and how firm is that date?
- How many working days on site do you expect?
- What happens on rain days?
- Who is coordinating the solar installer and any other trades?
- How will you protect the house if the job is interrupted?
