Re-Roofing Cape Town means removing the old covering and re-covering the same structure. The trusses, rafters and overall roof shape stay, while the tiles or sheets, battens, underlay and flashings are replaced.
It falls between a repair and a complete rebuild, and it is the right choice when the covering is worn out but the timbers below are still in good condition. Get prices from roofers who re-cover roofs as a regular part of their work.
Roof area, existing covering, what you would like to re-cover in, and the suburb you are in.

People often treat these as the same thing, but they are not. Re-roofing puts a new covering on the existing structure. Roof replacement in Cape Town is the bigger job and may involve the structure itself, a change of roof shape, or rebuilding after the structure has failed. Re-roofing costs less because structural work is limited to fixing whatever turns up during the strip.
| Re-roofing | Complete replacement | |
|---|---|---|
| Structure | Retained, repaired where required | May be partly or fully rebuilt |
| Roof shape | Unchanged | Can change |
| Battens and underlayment | Renewed | Renewed |
| Usual duration | 4 – 10 days on a house | 1 – 3 weeks |
| Plans needed | Generally not for like-for-like | Frequently, where the structure changes |
Typical Roof Conversions
- Concrete tile to IBR sheeting. The most frequent re-roof in Cape Town. Removes about 40 kg/m² of dead load, installs fast and fits the wind well when the right way fixed. The purlin layout changes from tile battens.
- Old corrugated iron to new sheeting. A direct swap on cottages and outbuildings, normally adding underlay where there was none before.
- Asbestos cement sheets to new sheeting. A registered asbestos contractor must take the old sheets off before the new roof is fitted. See asbestos roof removal in Cape Town.
- Sheeting to concrete tiles. It can be done, but a qualified person must check the structure first, because the weight goes up several times.
- Tile to tile. Where the look must stay, normally on heritage or estate-controlled homes and buildings.
What A Roof Strip Uncovers
You cannot see what is under a covering until it comes off. Expect the roofer to report on rotten or borer-damaged battens, purlins spaced wrongly for the new material, split or sagging truss members, and underlay that has broken down or was never fitted. That is why a well-prepared re-roofing quote includes a provisional amount for timber instead of a fixed total. A quote with no timber allowance is either hopeful or setting up a variation order later.

Ballpark Cape Town figures, not firm quotes. The figure moves most with truck access, whether old sheets can be dropped or must be lowered by hand, the slope, the number of hips and valleys, and how sound the timber is.

Compare Re-Roofing QuotesStaying At Home While The Roof Is Redone
Yes, most people stay. The work happens outside, the roof is stripped and re-covered one section at a time, and the roof void is opened from above rather than through the ceilings. Expect early-morning noise, dust in the roof space and some cracks in older ceilings. Empty the roof space first and cover anything you store up there. Rain while sections are open is the main risk, so agree in writing how open areas will be covered overnight.
Adding Insulation And Vents While The Roof Is Open
Re-roofing is the one affordable chance to add under-sheet insulation and fix poor ventilation. Fitting roof insulation in Cape Town now costs a small portion of what a later retrofit would, and installing ridge vents or whirlybirds with the covering off means nobody has to cut into a finished roof down the line.
Common Questions
How do re-roofing and roof replacement differ?
Re-roofing replaces the covering, battens and underlay on the structure that is already there. Replacement is a larger job that can involve rebuilding the structure or changing the roof shape. Where the timber is in good condition, re-roofing is cheaper and quicker.
How much time does re-roofing take?
A single-storey home of 120 to 180 m² usually takes four to ten working days. Hips, roof valleys, two-storey and wood repairs extend that.
Am I able to re-roof from tiles to sheeting?
Yes, and it is the most frequent conversion in Cape Town. The load drops considerably, the purlin layout changes and the roof installs faster. Check the minimum slope for the sheeting profile you choose.
Do I need council sign-off to re-roof?
Re-covering an existing roof with the same material normally does not need plans. Switching material or changing the slope, height or shape of the roof generally does, and heritage-protected buildings have extra rules. Check with the City before work starts.
What if the wood underneath is decayed?
It is swapped out during the re-roof. A good quote carries a contingency allowance for this, so you only pay for what is really used and there is no disagreement mid-job.
Am I able to re-roof over the existing covering?
New sheets over old sheets are sometimes used on industrial buildings as an overlay. On houses it traps moisture, adds weight and hides decay, so it is usually best avoided.
Is re-roofing less expensive than replacing the entire roof?
Normally, because the structure is retained. Expect about R520-R900 per m² for a tile-to-sheet conversion against a higher figure where roof trusses are rebuilt.
Will a re-roof damage my ceilings?
Largely, though some cracking is common on ageing ceilings from vibration. Making good is normally left out from roofing quotes, so ask if you would like it covered.
