Building Materials Prices in Ghana (2026): Cement, Blocks, Iron Rods & Roofing
Current prices of cement, sandcrete blocks, iron rods, roofing sheets and sand in Ghana for 2026, plus how to estimate quantities and buy smart.
Key takeaways
- A 50 kg bag of cement costs roughly GH₵110–GH₵125 in Greater Accra in 2026, depending on brand and grade.
- 6-inch sandcrete blocks typically sell for about GH₵5–GH₵9 each; quality varies widely, so check curing and cement content.
- A 12-metre length of 12 mm iron rod costs around GH₵110–GH₵170, and 16 mm around GH₵190–GH₵280.
- Prices follow the cedi and fuel costs, so confirm with suppliers on the day you buy and lock in bulk purchases when prices are stable.
Material costs make up the majority of any construction budget in Ghana, and they move quickly. This guide gives you indicative 2026 prices for the most important building materials, explains what drives them, and shows how to buy smart.
Important: These are indicative Greater Accra prices as of October 2026, gathered from market trackers and supplier quotes. Prices vary by supplier, quantity, location and week. Always confirm on the day you buy.
Cement prices in Ghana (2026)
Cement is the backbone of Ghanaian construction. It goes into foundations, columns, slabs, blocks, plastering and screeding.
| Brand / grade | Indicative price (50 kg bag) |
|---|---|
| Ghacem Super Strong (42.5N) | GH₵110–GH₵120 |
| Ghacem Extra (42.5R) | GH₵115–GH₵125 |
| Dangote (42.5) | GH₵108–GH₵118 |
| Other brands (Diamond, CIMAF, etc.) | GH₵100–GH₵120 |
Why prices change: clinker and gypsum are largely imported and paid for in US dollars, so cement prices track the cedi exchange rate, fuel and transport costs. Prices tend to rise during the peak building season when demand is high.
Which grade to use: 42.5R (rapid-hardening) gains strength faster and suits structural concrete; 42.5N is widely used for general work. Your structural engineer will specify the right grade.
Sandcrete block prices
| Block type | Indicative price per block |
|---|---|
| 5-inch hollow block | GH₵4–GH₵7 |
| 6-inch hollow block | GH₵5–GH₵9 |
| 6-inch solid / load-bearing block | GH₵8–GH₵10 |
Block quality varies enormously in Ghana. A good block is made with the right cement-to-sand ratio, compacted well and cured with water for several days before use. Ask your supplier how blocks are cured, check that they don't crumble at the corners, and avoid blocks that are still damp and pale from the mould.
Iron rod (reinforcement steel) prices
| Size | Indicative price (12 m length) |
|---|---|
| 10 mm | GH₵80–GH₵120 |
| 12 mm | GH₵110–GH₵170 |
| 16 mm | GH₵190–GH₵280 |
| Bulk (per tonne) | roughly GH₵10,000+ |
Always buy rods that match your structural drawings. Never substitute a smaller diameter to save money. Check for rust flaking, bends and genuine markings; reputable suppliers can show you mill certificates.
Roofing sheet prices
| Roofing type | Indicative price |
|---|---|
| Aluminium/zinc sheet (gauge 30) | GH₵130–GH₵220 per sheet |
| Long-span aluminium (per m²) | GH₵120–GH₵260 |
| Stone-coated steel tiles | Higher; priced per m² by brand and warranty |
Thicker gauges (a lower gauge number) are stronger and more durable, especially in windy or coastal areas. Near the sea, in towns such as Takoradi, Tema or Cape Coast, choose corrosion-resistant sheets and fixings. Our guide to designing for Ghana's climate covers roof choices in more detail.
Sand, stones and aggregates
Sand and stone ("chippings") are usually sold by the trip (truckload). Prices depend heavily on the size of the truck, the quarry and the distance to your site, so get quotes from several suppliers near you. Insist on clean, washed sand for concrete and plaster, because sand with too much silt or salt weakens concrete.
How to estimate quantities
Guessing quantities leads to either expensive shortfalls or wasted materials. The right way is a Bill of Quantities (BOQ) prepared from your architectural and structural drawings. A BOQ lists every item (bags of cement, number of blocks, lengths of each rod size, roofing sheets) so you can:
- budget accurately before you start,
- compare supplier and contractor quotes fairly, and
- track materials delivered to site against what was planned.
Our permits, costing and consultation service prepares BOQs for clients who already have drawings.
Typical concrete and mortar mixes
Your structural engineer specifies the concrete for each element, but it helps to understand the common nominal mixes used on Ghanaian sites (by volume of cement : sand : aggregate):
| Mix | Typical use |
|---|---|
| 1 : 1.5 : 3 | Richer structural concrete for demanding elements, as specified |
| 1 : 2 : 4 | Common general-purpose structural concrete for columns, beams and slabs |
| 1 : 3 : 6 | Blinding and mass concrete beneath foundations |
| 1 : 4 to 1 : 6 (cement : sand) | Mortar for blockwork |
| 1 : 4 to 1 : 5 (cement : sand) | Plastering and rendering |
Two rules matter as much as the mix itself: don't add extra water to make concrete easier to work (it weakens it), and cure concrete properly by keeping it moist for several days after pouring.
How to check material quality on delivery
- Cement: bags should be sealed and dry, with a recent manufacturing date. Hard lumps mean the cement has been exposed to moisture.
- Blocks: check for uniform size, firm corners and a consistent grey colour. Properly cured blocks feel solid and don't crumble when you rub the edges.
- Iron rods: measure the diameter with a caliper, check the markings and reject heavily rusted or pitted rods. Light surface rust is normal.
- Sand: a simple jar test helps. Shake sand with water in a clear jar and let it settle. A thick layer of silt on top is a warning sign.
- Roofing sheets: confirm the gauge and coating you paid for; a micrometer settles any doubt.
- Timber: use seasoned timber that has been treated against termites, especially for roof structures.
Why prices move and when to buy
Several factors push Ghanaian material prices up and down:
- The cedi exchange rate: imported inputs such as clinker, steel and aluminium are priced in dollars.
- Fuel and transport costs: these feed directly into delivered prices, especially for sand, stone and blocks.
- Seasonal demand: building activity, and demand for materials, tends to peak in the drier months.
- Supplier competition: prices differ noticeably between suppliers, so it pays to get several quotes.
When prices are stable, buying the main materials for an entire stage at once protects you from later increases, provided you can store them safely.
Smart buying tips
- Buy in bulk for each stage to secure better prices and avoid repeated delivery charges.
- Lock in prices when the cedi is stable, especially for cement, rods and roofing.
- Store materials properly. Keep cement off the ground and covered; it hardens if exposed to moisture.
- Control site stock. Keep a simple delivery and usage log to prevent theft and wastage.
- Don't compromise on structural materials to save money. Foundations, columns and slabs must be built to the engineer's specification.

Frequently asked questions
How much is a bag of cement in Ghana today?
In 2026 a 50 kg bag of cement in Greater Accra typically costs between GH₵110 and GH₵125. Popular brands include Ghacem, Dangote and Diamond, with higher-strength grades (42.5R) priced slightly above standard grades. Prices change frequently, so confirm with your supplier.
How many blocks do I need for a 3-bedroom house?
A typical 3-bedroom bungalow uses roughly 3,500–5,000 six-inch blocks for walls and fence-free construction, but the exact number depends on wall lengths, heights and openings. Your architect or quantity surveyor should calculate it from the drawings in the Bill of Quantities.
Is it cheaper to mould my own blocks?
Moulding on site can save money and give you control over quality, as long as you use the correct cement-to-sand ratio and cure the blocks properly for several days. Poorly made blocks crack and crumble, so cheap blocks often become expensive.
