Our Process
How Our Skylight Installation Works
We've installed skylights across San Jose neighborhoods for 16 years. Here's our straightforward approach from first call to finished roof.
- Free On-Site Inspection
We visit your home, assess your attic structure and roof pitch, and discuss placement for maximum light without compromising your roof's integrity. No obligation, no sales pitch. - Custom Plan & Material Selection
We recommend the right skylight—fixed, vented, or tubular—from brands like Velux or Fakro. We'll show you options for energy-efficient glass, flashing kits, and any necessary deck modifications. - Professional Installation
Our crew removes old roofing around the opening, installs the skylight with proper flashing and insulation, and seals everything to prevent leaks. We work clean and protect your landscaping. - Final Walkthrough & Cleanup
We inspect the seal, test operation, and clean up all debris. You get a workmanship warranty and our cleanup guarantee—no leftover shingles or nails in your yard.

Quick Answers
Frequently Asked Questions About Skylight Installation
We've been installing skylights in San Jose homes for 16 years. Here are answers to the questions we hear most often from homeowners in Willow Glen, Cupertino, and beyond.
How much does skylight installation cost in San Jose?
Cost depends on roof type, skylight size, and flashing complexity. For a standard fixed skylight on a composition shingle roof, expect $1,500–$3,000 installed. Vented or solar-powered models run higher. We provide free, no-obligation estimates after inspecting your roof and attic.
Can you install a skylight on any roof type?
We've installed on tile, composition shingle, metal, and flat roofs across the South Bay. Each requires specific flashing and curb details. We're factory-certified for Malarkey, CertainTeed, GAF, and Owens Corning, so we match the right skylight and flashing to your existing roof system.
Do skylights leak?
A properly installed skylight shouldn't leak. The key is correct flashing integration with your roof. We've been doing this since 2010 and every install comes with a workmanship warranty and a cleanup guarantee. We also handle insurance claims if an existing skylight causes water damage.
How long does installation take?
Most residential skylight installations take one to two days. We work with a crew of 3–4, and we clean up every day before we leave. If we're replacing an old skylight, it's usually a one-day job.
Do you offer solar-powered or vented skylights?
Yes. We install fixed, vented, and solar-powered skylights from major manufacturers. Vented models are great for bathroom or kitchen exhaust, and solar-powered units don't require wiring. We'll help you choose based on your room's orientation and needs.
Will a skylight make my home too hot in summer?
Modern skylights use low-E glass and argon gas fills to minimize heat gain. We can also recommend blinds or shades. In our experience, a well-placed skylight actually reduces lighting-related heat since you rely less on incandescent bulbs during the day.
Do I need a permit for a skylight in San Jose?
Yes, San Jose requires a building permit for skylight installation. We handle the permit process as part of our service. Our team pulls the permit, schedules inspections, and ensures everything meets current code. We're licensed (CA CSLB #1087234) and bonded.
What brands of skylights do you install?
We're factory-certified for Velux and Fakro, two of the most trusted names in skylights. Both offer excellent warranties and energy performance. We'll walk you through the options during your free estimate.
