- 250 sq. ft.: $20,000–$50,000
Tip: For larger dormers, per square foot costs tend to decrease slightly, making bigger additions more cost-effective.
Dormer Addition Cost by Material
The choice of materials can heavily influence the cost:
- Asphalt Roofing: $4–$10 per sq. ft. (Budget-friendly, but less durable)
- Metal Roofing: $8–$22 per sq. ft. (Higher upfront cost but lasts longer)
- Slate Roofing: $12–$20 per sq. ft. (Premium choice with great durability)
Example: Opting for metal roofing might cost more initially, but its longevity can save you money over time.
Cost to Install a Dormer by Style
Each dormer style comes with unique benefits and costs. Here’s a look at some popular styles:
- Gable Dormers: $110–$150 per sq. ft. (Great for curb appeal and natural light)
- Shed Dormers: $80–$120 per sq. ft. (More interior space, easier to construct)
- Prefab Dormers: $70–$100 per sq. ft. (Lower labor costs, faster installation)
Real-world example: A homeowner opted for a shed dormer to add space efficiently, saving 15% on construction costs compared to a gable dormer.
Additional Cost Factors
Beyond materials and style, several other factors can impact the total cost of adding a dormer:
- Roof Removal: Removing existing roofing costs between $5 and $8 per square foot.
- Foundation Reinforcement: If needed, this can add $4,000 to $12,000 to your project.
- Permits: Expect to pay between $400 and $2,000, depending on your local regulations.
Tips and Reminders
- Opt for Simpler Designs: Complex designs increase costs.
- Standard Windows: Choose standard-sized windows to save on custom costs.
- Shop for Materials: Sometimes, sourcing your materials can save money.
- Consider Prefab Dormers: These can reduce labor costs significantly.
- DIY Finishing: If you're handy, consider doing the interior finishing yourself.
