What Makes a Surrey Roof Replacement More or Less Expensive
- Roof area — measured in squares (1 square = 100 sq ft). More area = more material and labour.
- Pitch (steepness) — roofs steeper than 6/12 require additional safety equipment and take longer to install.
- Number of existing layers — 2-layer tear-off adds $500–$1,000 to disposal and labour cost.
- Decking repair — rotted plywood found during tear-off adds $80–$180 per sheet; older Surrey homes may need 5–15 sheets replaced.
- Shingle quality tier — standard architectural vs premium impact-resistant adds $800–$2,500 in material cost.
- Valley count — each valley requires additional flashing and careful shingle work; complex rooflines with 6+ valleys cost noticeably more than simple gable roofs.
