Pro Tips

Sun tunnels are the budget alternative — $400-$1,000 installed, they bring natural light to dark hallways, closets, and bathrooms without the structural complexity of a full skylight
VELUX solar-powered skylights qualify for a 30% tax credit — The solar-powered opener and blind qualify for the residential clean energy credit. A $2,000 skylight = $600 tax credit
Proper flashing prevents 95% of skylight leaks — Skylights don't leak — bad installation does. Ensure your installer uses a complete flashing kit (not just caulk). This is the #1 quality differentiator
North-facing skylights provide consistent light without heat gain — South-facing skylights are too hot in summer and contribute to cooling costs. North-facing gives even, glare-free light year-round
Add a skylight blind for temperature control — A $200-$400 blind (manual or solar) blocks heat in summer and insulates in winter. Without one, skylights add $50-$150/year to cooling costs
Replace old skylights during roof replacement — If you're getting a new roof, replacing old skylights at the same time saves $300-$600 per skylight in labor (roofers are already up there)

What You Need to Know

Skylights add natural light to dark rooms, reduce electricity costs, and create architectural interest. Modern skylights with low-E glass and proper flashing are leak-free when installed correctly. The most common options: fixed skylights ($500-$1,500) for light only, venting skylights ($1,000-$2,500) for light and ventilation, and sun tunnels ($400-$1,000) for small spaces.
