What Affects New Roof Cost?
Roof Size & Pitch
Steeper roofs require more safety equipment. Larger roofs take longer and need more materials.
Material Choice
Natural slate costs 2-3x concrete but lasts 100+ years vs 40-50 years.
Access Difficulty
Narrow gardens, extensions, or conservatories can increase scaffolding costs.
Condition of Timbers
Rotten rafters or battens must be replaced. This can't be assessed until old roof is removed.
