Roof Replacement Cost in California
Average pricing to tear off and replace an asphalt shingle roof.
Overview
A roof replacement includes tearing off the old roofing material, inspecting and repairing the decking underneath, and installing new underlayment, flashing, and shingles (or another material).
Most residential roofs use asphalt shingles, though metal, tile, and flat roofing are common depending on region and home style.
Why California prices differ
Coastal and hurricane-prone regions often require higher wind-rated materials and additional fasteners, raising cost. Northern climates may need ice-and-water shield underlayment.
Frequently asked questions
How long does an asphalt shingle roof last?
A properly installed asphalt shingle roof typically lasts 20-30 years depending on climate and shingle quality.
Can I install a new roof over the old one?
Some jurisdictions allow one layer of overlay, but a full tear-off is recommended since it lets installers inspect and repair the decking underneath.
