The cost of roofing materials can vary greatly, depending on the type and quality of the material. Here are some approximate costs of different roofing materials:

• Asphalt shingles: £30 to £100 per square meter
• Clay tiles: £50 to £200 per square meter
• Slate tiles: £80 to £300 per square meter
• Metal roofing: £60 to £250 per square meter
• Flat roofing materials: £40 to £150 per square meter

If your roof is damaged or old, you may be wondering whether to replace it entirely or repair it. The cost of a new roof can be higher than a roof replacement, but it's often a better investment in the long run. A new roof can last for 20 to 30 years or more, depending on the materials used, while a roof replacement may only last for 10 to 20 years.

Proper insulation is essential for any roof, as it can help reduce heat loss and energy bills. The cost of insulation can vary depending on the type and quality of the material, but it's often a worthwhile investment. On average, insulation can cost around £500 to £2,000, depending on the size of the roof and the type of insulation used.
