Why Does House Type Affect Roof Replacement Cost?
House type is the most useful starting point when budgeting for a new roof.
It tells you roughly how large the roof is, how complex it is likely to be and how much scaffolding is required.
A terraced house has a smaller footprint, shares side walls and usually only needs scaffolding on two sides. A large detached property has a bigger roof area, potentially a more complex layout and needs scaffolding all around.

Terraced House Roof Replacement Cost
Terraced houses are the most affordable to re-roof in Ireland because they have smaller footprints and share party walls.
Typical roof area: 45–60 m² Typical crew time: 3–4 days
Cost breakdown by material
| Material | Total installed (excl. scaffold) | Scaffold to add |
|---|---|---|
| Concrete tile | €4,500–€6,500 | €800–€1,400 |
| Synthetic slate | €5,000–€7,500 | €800–€1,400 |
| Natural slate | €6,500–€11,000 | €800–€1,400 |
What drives cost up on a terraced house
Narrow access is the main one. On a tight city terrace, getting a skip positioned or scaffolding erected can be complicated by parking restrictions and pavement space. This adds to the scaffolding cost.
Older terraced properties in Dublin, Cork and Galway often have period features such as ornate ridge work or original Welsh slate that requires careful matching or specialist sourcing.
Semi-Detached House Roof Replacement Cost
The semi-D is by far the most common house type in Ireland. Most of the national average pricing you see is based on this property type.
Typical roof area: 70–90 m² Typical crew time: 4–6 days
Cost breakdown by material
| Material | Total installed (excl. scaffold) | Scaffold to add |
|---|---|---|
| Concrete tile | €6,500–€9,500 | €1,200–€2,000 |
| Synthetic slate | €7,000–€10,500 | €1,200–€2,000 |
| Clay tile | €7,500–€12,000 | €1,200–€2,000 |
| Natural slate | €9,500–€15,000 | €1,200–€2,000 |
Worked example: a standard semi-D in Cork
A 3-bedroom semi-detached house in Cork city. Roof area approximately 82 m². Full strip and re-tile with concrete tile, new breathable membrane, new battens. Skip hire included.
- Materials and labour: €7,200
- Scaffolding: €1,600
- Chimney repoint and new flashing: €700
- Contingency (15%): €1,080
- Total budget: approx €10,580
Detached 3-Bedroom House Roof Replacement Cost
A detached three-bedroom house typically has a more complex roofline than a semi-D. Hip returns, side extensions and additional chimney positions are common.
Typical roof area: 110–135 m² Typical crew time: 5–8 days
Cost breakdown by material
| Material | Total installed (excl. scaffold) | Scaffold to add |
|---|---|---|
| Concrete tile | €9,500–€14,000 | €1,800–€2,800 |
| Synthetic slate | €10,500–€16,000 | €1,800–€2,800 |
| Natural slate | €14,000–€21,000 | €1,800–€2,800 |
| Zinc | €14,000–€22,000 | €1,800–€2,800 |
What makes detached properties more expensive per m²
More hips and valleys mean more cutting, more waste and more lead or aluminium flashing detail. Each valley on a tiled roof adds roughly 10–15 hours of labour.
If the house has a two-storey return or a single-storey extension, that section of roof is usually done at the same time, increasing total area.
Bungalow Roof Replacement Cost
Bungalows often have larger footprints than two-storey houses of the same bedroom count, because they spread outward rather than upward.
Typical roof area: 120–160 m² Typical crew time: 5–9 days
Cost breakdown by material
| Material | Total installed (excl. scaffold) | Scaffold to add |
|---|---|---|
| Concrete tile | €10,000–€16,000 | €1,600–€2,400 |
| Synthetic slate | €11,000–€18,000 | €1,600–€2,400 |
| Natural slate | €15,000–€24,000 | €1,600–€2,400 |
Bungalow-specific considerations
Many Irish bungalows built in the 1970s and 1980s have low-pitch roofs. If your pitch is under 22 degrees, standard concrete tiles cannot be used. You will need a low-pitch profile tile or a flat-roof system for the affected sections.
Low-pitch roofs also require extra care with the membrane lap and batten spacing to prevent wind-driven rain penetrating at the tile joints.

Detached 4-Bedroom or Larger House
Larger detached homes often have more complex rooflines, higher eaves and multiple chimney positions. Scaffolding costs are proportionally higher because of the longer perimeter.
Typical roof area: 145–200 m² Typical crew time: 7–12 days
Cost breakdown by material
| Material | Total installed (excl. scaffold) | Scaffold to add |
|---|---|---|
| Concrete tile | €13,000–€20,000 | €2,200–€3,500 |
| Natural slate | €18,000–€29,000 | €2,200–€3,500 |
| Zinc | €18,000–€32,000 | €2,200–€3,500 |
The Cost Nobody Mentions: Hidden Structural Work
This applies to all house types and it is the most common reason a job runs over budget.
When the old tiles and battens are stripped, the contractor can inspect the rafters and ridge board directly for the first time.
On houses built before 1990, it is common to find:
- Three to six rafters with rotten lower sections needing cutting back and splicing
- A sagging ridge board needing full replacement
- Damaged wall plate sections at the eaves
- Undersized or poorly fixed hip rafters
Budget for this regardless of house type.
A 10–15% contingency on top of your quote is sensible for any house over 25 years old.
Rafter repairs typically run €400–€800 per rafter. A full ridge board replacement on a semi-D adds €600–€1,200 to the job.

How to Get an Accurate Quote for Your House Type
Before any contractor visits, prepare the following:
- Rough roof area — calculated from ground-floor footprint × 1.4 (standard pitch)
- Approximate age of existing roof — check original purchase documents or ask neighbours
- Material preference — or ask for quotes on two options (concrete tile vs synthetic slate is a common comparison)
- Known issues — any existing leaks, moss problems, cracked mortar
When the contractor visits:
- Ask them to specify whether they are quoting a full strip or an overlay
- Confirm scaffolding is quoted separately as a line item
- Ask what happens if structural problems are found during the strip

Frequently Asked Questions
How much does it cost to replace the roof on a 3-bed semi-detached house in Ireland?
For a standard 3-bed semi-D with concrete tile, budget €7,500–€12,000 fully installed including scaffolding and skip hire. Natural slate on the same house runs €11,000–€17,000.
Is a bungalow more expensive to re-roof than a semi-detached?
Usually yes, because bungalows have larger footprints. The total area is typically 30–50% bigger than a comparable semi-D, which means more materials and more labour. However, scaffolding is simpler because there is only one storey.
Do I need planning permission to replace the roof on my house?
Not for a like-for-like replacement. Planning permission is required only if you are significantly changing the roof form, adding front-facing skylights or working on a protected structure.
Does the size of my house affect the scaffold cost proportionally?
Scaffolding cost is driven by perimeter and height, not area. A bungalow with a large footprint can actually cost less to scaffold than a two-storey semi-D with a similar roof area, because it is lower. A terraced house in a narrow city street can cost as much to scaffold as a detached house.
What is included in the costs on this page?
Materials, labour, new breathable membrane, new battens, tiles, ridge tiles, standard flashings, skip hire and VAT at 13.5%. Scaffolding, structural repairs and extras such as chimney work, Velux replacement or new gutters are not included.
