Material Comparison
Choose the material that fits your budget and needs — prices are market estimates, confirmed after a site visit
| Material | Pros | Cons |
|---|---|---|
| Zinc / polycarbonate roof (on steel structure) | Cheapest option for an extension roof, quick to install, lightweight | Noisy in heavy rain, hotter than tiles, condensation on polycarbonate |
| Concrete / clay tile roof (on timber or steel rafters) | Better heat resistance, quiet in the rain, matches the main roof | Heavier (needs a stronger frame), higher cost, takes longer to install |
| IBS / prefab structure (precast concrete panels or AAC lightweight blocks) | Faster construction, less site dust, lighter than ordinary brick, fire-resistant | Material cost is higher than red brick, skilled IBS workers must be sourced, the join to the old structure needs care |
