Cosy Roof Cost Calculator | Estimate Your Roof Price

Our calculator provides estimates based on current UK market averages for materials and labour. The actual cost can vary by ±15-20% depending on specific factors such as roof complexity, accessibility, contractor rates in your area, and current material prices. We recommend getting quotes from at least 3 local contractors for a more precise estimate.

Several factors influence roofing costs:

• Roof size and complexity: Larger roofs and complex designs require more materials and labour
• Material choice: Premium materials like natural slate cost more than concrete tiles
• Location: Labour costs vary significantly across UK regions
• Accessibility: Difficult-to-reach roofs may require additional scaffolding
• Roof condition: Existing damage or structural issues increase costs
• Additional features: Insulation, skylights, and guttering add to the total

Yes, certain factors can increase costs:

• Complex roof types: Mansard and hipped roofs require more labour than simple pitched roofs
• London & South East: Typically 15-25% higher costs due to increased labour rates
• Listed buildings: May require special materials and planning permission
• High-rise properties: Additional scaffolding and safety measures increase costs
