What Affects Your Price
7 factors that determine your roof cost.
1. Roof Size
The average Central Valley home has 1,500–2,500 sq ft of roof area. Bigger homes cost more total. But the per-square-foot price drops on larger projects.
2. Pitch and Complexity
Steep pitches, many valleys, dormers, and skylights increase labor time. A simple hip roof costs less than a multi-gable design with 12 valleys.
3. Material Choice
3-tab shingles are cheapest upfront but last half as long as architectural shingles. Cost-per-year is often better with premium materials.
4. Tear-Off vs. Overlay
California code limits shingle layering. If you have two layers already, full tear-off is needed — adding $1,000–$3,000 to the project.
5. Decking Repairs
Rotted or damaged plywood decking found during tear-off adds $50–$100 per sheet replaced. Most roofs need 0–5 sheets.
6. Permit Fees
Building permits add $200–$500 depending on your city. We handle all permitting — it's included in our quote.
7. Warranty Level
Standard maker warranties are included. Extended warranties (like OC Platinum Cover up to 50 years) add $500–$1,500.
