Solar tubes are a cost-effective alternative to skylights, offering natural light with easier installation and minimal home alterations.

Solar Tube Pricing by Size

• 10-inch tube: $150–$350.
• 14-inch tube: $400–$550.
• 18-inch tube: $600–$750.
• 19-inch or larger: $800 and up.
• 21-inch tube (special order for non-standard rafters): $900–$1,000.

Labor Costs

• Installation per tube: $150–$250.
• Additional costs for non-asphalt roofs:
• Flashing adapter: $70–$100 (materials), $100–$150 (installed).

Factors Affecting Installation Costs

• Rafter Spacing:

• Non-standard spacing (24 inches apart) may require custom 21-inch tubes costing $900–$1,000 each.

• Roof Type:

• Asphalt roofs are ideal; other materials (e.g., tile, wood, metal) need adapters, adding $70–$150 per tube.

• Local Climate:

• Insulation to reduce condensation costs ~$0.90/sq. ft., adding $50–$100 for labor.

DIY Installation Costs

• DIY Kits: $200–$700 (materials only).
• Advantages:
• Easier than skylights—no need for framing, drywall, or repainting.
• Lower risk of heavy lifting.
• Risks:
• Potential for water leaks if improperly sealed.
• Could void roof warranty.

DIY vs. Hiring a Pro

• DIY:
• Suitable for skilled homeowners.
• Requires precise roof and ceiling cuts to avoid damage.
• Professional Installation:
• Safer, especially for waterproofing and roof integrity.
• Prevents costly repairs due to errors.

Benefits of Solar Tubes

• Cost-Effective: Cheaper than skylights.
• Energy Efficient: Provides natural light without heat transfer.
• Simple Installation: Minimal structural changes required.

Pro Tip: Choose R-15 or R-19 insulation for humid climates to avoid condensation inside the tubes.
