What's included in a full roof replacement
- Tear-off — all old shingles + underlayment removed
- Deck inspection — rotted CDX sheathing replaced
- Ice-and-water shield — 6 ft at eaves (NJ code), valleys, around penetrations

Factors that change your price
- Pitch. Steeper = slower + safer equipment = more labor.
- Peaks, valleys, dormers. More flashing, more cuts, more labor.
- Skylights. Each adds $300–$800 for flashing; replacement $600–$2,500 if dated.
- Chimneys. New flashing $400–$1,500 each.
- Height. 3-story homes cost more than 1-story ranch.
- Access. Tight lots, fences, landscaping all affect labor.
- Hidden deck rot. Not always visible pre-install; budget 2–4 sheets of CDX.
