1. Roof Pitch & Complexity
Steep-slope roofs (8/12 pitch and greater) require specialized scaffolding, safety harnesses, and slower shingle placement, increasing labor hours compared to walkable 4/12 ranches.
2. Existing Roof Layers
New Jersey building codes permit a maximum of 2 roof layers. If your home has multiple existing layers, tear-off and disposal fees increase due to additional tonnage hauled.
3. Plywood Decking Condition
During tear-off, rotted or delaminated plywood sheathing must be replaced before installing underlayments. Plywood replacement typically averages $75 to $110 per 4x8 sheet installed.
