What moves the price
- Access. A roof hatch and a ladder is cheap; a lift, a crane or a three-story parapet is not.
- Fall protection. Crews working near unprotected edges need guardrails, nets or personal fall arrest under OSHA 1926.501. Set-up time is part of every repair.
- Wet insulation. A leak that has soaked the insulation turns a patch into a tear-out, often several times the cost.
- Warranty. A roof under manufacturer warranty may need a certified installer, which can cost more but keeps the warranty alive.
- Season and storms. After a regional hail or wind event, demand and prices rise.
