Roof Replacement Cape Town covers taking an existing roof off and putting a new one on: covering, underlay, battens and, where necessary, the structure beneath. Compare up to 5 quotes from roofing contractors who do full replacements rather than repairs.
This is the largest single piece of maintenance most properties ever need, and quotes for the same roof routinely differ by 50% or more because contractors scope it differently. The content below is aimed at making those quotes comparable.

Get Roof Replacement QuotesWhen Replacement Beats Repair
- Repeat leaks in different places. One leak is a fault. Four leaks in three winters is a system at the end of its life.
- Perished underlay throughout. Once the membrane under the tiles has turned brittle, every wind-driven rain event finds a way in and no amount of tile work fixes it.
- Widespread corrosion. Rust through the sheet rather than surface rust, particularly at laps and fixing points.
- Failed fixings across the roof. Perished washers and elongated screw holes everywhere, not in one patch.
- Sagging or deflection. Visible dips along the ridge or between trusses point at the structure, not the covering.
- A repair bill approaching a third of replacement. At that point replacement usually gives better value per year of service.
Replacement Options
| New covering | Notes | Expected life |
|---|---|---|
| Concrete tiles | Heavy, needs adequate structure, wide colour range | 30 – 50 years |
| Clay tiles | Colour is through the body, does not fade, higher cost | 50 years plus |
| IBR sheeting | Light, fast to install, suits lower pitches | 20 – 40 years |
| Corrugated sheeting | Traditional profile, common on Cape cottages and outbuildings | 20 – 40 years |
| Standing seam / concealed fix | No exposed fasteners, architectural finish, higher cost | 40 years plus |
| Fibre cement slate | Slate look at lower weight and cost than natural | 25 – 40 years |
| Natural slate | Heritage properties, heavy, specialist installation | 75 years plus |
Changing material type is where structure becomes a question. Going from sheeting to concrete tiles roughly quadruples the dead load, so the trusses and purlins have to be assessed and often strengthened. Going the other way, from tiles to sheeting, is usually straightforward. Any quote that changes the covering type without mentioning the structure is incomplete.
What Happens During A Replacement
- Roof measured, structure inspected and material selected
- Scaffolding or edge protection erected where the height requires it
- Old covering stripped, loaded and removed from site
- Timber inspected, rotten or borer-damaged members replaced
- New battens or purlins fixed, underlay or insulation laid
- New covering installed, starting at the eaves and working up
- Ridges, hips, valleys and flashings detailed and sealed
- Gutters refitted or replaced, site cleaned and rubble removed
The roof is open between the strip and the new covering going on. On a house that is typically one to three days. Ask every contractor how they intend to protect the building if it rains mid-job, and get the answer in writing.

Indicative Cape Town ranges, not quotations. Pitch, height, roof geometry, how many valleys and hips there are, access for a truck and crane, material choice and the state of the timber underneath are what separate a R90,000 job from a R200,000 one on the same size roof.
Get the full replacement priced, including the timber allowance and the rubble, rather than a headline rate per square metre.
Compare Replacement QuotesWhat Should Be In The Quote
Named material, profile and gauge. Underlay grade. Whether battens and purlins are new or reused. A stated provisional sum for rotten timber. Rubble removal. Scaffolding included or excluded. Gutters. Making good the ceilings if they are disturbed. Workmanship guarantee in years. If any of those are missing, the number is not comparable to a quote that has them.
Property Types
Standalone houses, semi-detached homes, townhouses within complexes, sectional title blocks where the body corporate carries the roof, small office buildings and retail units. On complexes and body corporate roofs, the approval process usually takes longer than the work does, so start collecting quotes well ahead of the AGM rather than after the first leak.
Frequently Asked Questions
How much does a roof replacement cost in Cape Town?
Broadly R550 to R950 per square metre for sheeting and R650 to R1,150 for concrete tiles, including stripping the old roof. A typical 150 square metre house lands between R85,000 and R175,000 depending on material and access. These are indicative ranges only.
How long does a roof replacement take?
A single-storey house of 120 to 180 square metres is usually five to ten working days. Double storey, complex geometry or timber repairs push that to two or three weeks. Weather delays are normal in winter.
Do I have to move out during a roof replacement?
Generally no. It is noisy and dusty, the ceilings may be disturbed, and you should clear the roof space and cover furniture in the rooms below. Occupants with respiratory sensitivities sometimes prefer to be out for the strip.
Can I change from tiles to sheeting?
Yes, and it is a common change because sheeting is lighter and faster to install. Going the other way, from sheeting to tiles, means the structure has to carry roughly four times the weight and must be assessed first.
What happens if it rains while the roof is off?
Contractors strip in sections and cover open areas with sheeting overnight. Ask specifically how they handle it, because it is the single biggest risk in the job and quotes rarely mention it unless asked.
Will my ceilings be damaged?
Some cracking and dust is common, especially on older lath or board ceilings. Ask whether making good is included; it usually is not.
Does the quote include removing the old roof?
It should, but check. Strip, load, cart away and disposal is a real cost and some quotes exclude it to look sharper.
Should I replace the gutters at the same time?
Usually yes. The scaffolding is up, the fascias are exposed and the labour is already on site, so doing it together costs considerably less than a separate visit later.
Full replacements are among the larger jobs quoted through Roofing Contractors Cape Town, which is exactly why comparing several scopes matters.
