What affects the cost of a asphalt roof replacement
- Roof size & pitch
- Priced per square; steeper pitches need more safety measures and slower work, raising labour.
- Complexity
- Valleys, hips, dormers and skylights all add flashing and cutting versus a simple gable.
- Shingle grade
- Architectural shingles cost more than 3-tab but last 25–30 years and look markedly better.
- Tear-off & decking
- Removing old layers, disposal, and replacing any rotted decking add cost that isn't always in the base quote.

Asphalt roof replacement in Christchurch, NZ: common questions
General guidance for asphalt roof replacement projects — figures quoted are national averages; see the table above for Christchurch, NZ estimates.
How much does a new asphalt roof cost in 2026?
About $30,000 on average, from roughly $9,000 for a small simple roof to $45,000+ for a large, steep or complex one.
Does a new roof add value?
It recoups around 56% of its cost directly, but its real value is removing a major buyer and inspection objection — a failing roof can stop a sale.
How long does an asphalt roof last?
3-tab shingles last about 15–20 years; architectural shingles 25–30. Climate, ventilation and installation quality all affect lifespan.
Should I replace the roof before selling?
If it's near end-of-life or visibly failing, replacing (or at least crediting the buyer) usually smooths the sale more than leaving it.
