Skylight Types & Products We Install

We offer a wide selection of skylight options to fit your roof type, room layout, energy goals, and design preferences. Whether you’re upgrading an existing unit or planning a brand-new installation, we’ll help you choose the right style for your home or commercial space.

Fixed Skylights

Fixed skylights are sealed, non-opening units designed purely to allow daylight. Because they have no mechanical components, they are the most weather-resistant and lowest-maintenance skylight option available. A well-flashed fixed skylight installed on a proper curb will perform for 20+ years without issue.

Venting Skylights

Venting skylights open to allow hot air and moisture to escape creating a passive stack-effect ventilation system that reduces AC load in summer and eliminates bathroom humidity without a fan. Available in manual crank-operated and solar-powered motorized configurations.

Tubular Skylights

Tubular skylights capture daylight at the roofline through a small dome, channel it down through a highly reflective metal tube, and diffuse it through a ceiling fixture — delivering natural light to interior rooms, closets, hallways, and bathrooms that sit far below the roof or under a second story.

Architectural & Custom Skylights

For projects requiring something beyond a standard rectangular unit, we design and install:

Skylight Replacement & Glass-Only Upgrades

If your skylight is leaking or hazy but the curb and frame are intact, a glass-only replacement is the most cost-effective solution. We fabricate replacement panels for most major skylight brands in our in-house shop — including VELUX, Solatube, ODL, and generic contractor-grade units.

Our Skylight Installation Step by Step Process

We make skylight installation simple, code-compliant, and stress-free. From consultation to clean-up, our team follows a proven system that ensures performance, aesthetics, and peace of mind.

Free Roof & Space Assessment

We visit your home, evaluate your roof structure, slope, and framing, identify the optimal skylight location for sun angle and daylighting performance, and assess whether any structural reinforcement is required. We discuss every product option unit type, glass specification, frame style, and any smart/motorized features and answer every question before a quote is issued.

Permit Application & Title 24 Review

We identify all applicable permit requirements for your jurisdiction, prepare the necessary documentation (including structural drawings where required), calculate Title 24 compliance parameters, and submit to the City of Grass Valley or Nevada County Building Department. We do not schedule installation until permits are approved.

Precision Curb Construction & Flashing

The most critical phase of any skylight installation. We cut the roof opening to exact specifications, construct the curb (the raised platform the skylight unit mounts on) to the required height and slope, and install code-compliant step flashing, counter-flashing, and sealant in the correct sequence. Improper flashing is the cause of virtually every skylight leak. We do not rush this step.

Unit Installation & Interior Finish

We set and secure the skylight frame and glazing unit, test the operation of any venting mechanisms, install interior light wells or shaft extensions where required to bring the daylighting opening through the ceiling, and complete all interior drywall, trim, and paint-prep work.

The result reflects a realistic, code-compliant skylights installation designed to improve natural light without altering the surrounding structure or roof integrity.

The Real Benefits of Professional Skylight Installation

Lower Energy Bills
A properly positioned skylight reduces artificial lighting dependence by an estimated 5–10% of total lighting load. Venting skylights further reduce AC usage by exhausting hot air during summer evenings through passive stack ventilation.
Improved Ventilation & Indoor Air Quality
Opening skylights create a natural chimney effect: hot, stale air rises and exits through the roof window while fresh air enters at lower elevations. This is particularly effective in kitchens (cooking fumes) and bathrooms (humidity).
Proven Mood & Wellbeing Benefits
Research consistently links natural light exposure to improved mood, better sleep quality, and increased productivity. A skylight above a home office desk or kitchen island delivers broad-spectrum daylight that overhead electrical fixtures cannot replicate.
Increased Property Value
Well-installed skylights in kitchens, master baths, and living rooms consistently appear on appraisal upgrade lists. In NorCal's competitive real estate market, natural light is one of the most frequently cited features by buyers and a skylight is one of the most permanent ways to deliver it.
Eco-Friendly Daylighting
Natural light from a properly specified low-SHGC skylight costs nothing to operate, generates no emissions, and aligns with California's Title 24 daylighting mandate for new and remodeled residential construction.

California Code Compliance: Title 24, Permits & Structural Requirements

Skylight installation in California involves three compliance layers that most contractors handle incorrectly:

Title 24 California Energy Code

Title 24 Part 6 governs the energy performance of skylights through three key metrics:

Building Permits City of Grass Valley & Nevada County

New skylight installations and skylight replacements that alter the roof structure require permits in most Nevada County jurisdictions. We manage the complete submission process drawings, structural notes, Title 24 compliance documentation, and inspection scheduling.

Structural Assessment

California's foothill and mountain homes frequently have truss roof systems where cutting a skylight opening requires an engineered header and lateral blocking. We assess every roof before quoting and identify any structural modifications required to keep your installation code-compliant and structurally sound.

Skylight Maintenance & Emergency Leak Repair

A skylight is a roof penetration. Like any roof component, it benefits from periodic inspection and maintenance to maximize lifespan and prevent small issues from becoming expensive repairs.

Frequently Asked Questions About Skylight Installation

Will my skylight leak?

A properly installed skylight with correct step flashing, code-compliant counter-flashing, and appropriate sealant should never leak. Virtually all skylight leaks trace back to improper flashing installation either rushed, skipped, or done by a roofer without skylight-specific training. We back every installation with a leak-proof written warranty.

What is the difference between a fixed and venting skylight?

A fixed skylight is sealed and non-operable; it admits light only. A venting skylight opens (manually or via motor) to allow hot air and moisture to escape. Venting skylights cost more but deliver ventilation benefits that significantly improve comfort in kitchens, bathrooms, and bedrooms.

What is a tubular skylight (sun tunnel) and when should I choose one?

A tubular skylight channels daylight from a small roof dome through a highly reflective metal tube and diffuses it through a ceiling diffuser. It is ideal for interior rooms without direct roof access, hallways, closets, bathrooms under a second story where a traditional skylight cannot be installed. It is also significantly less expensive.

Does skylight installation require a permit in Grass Valley, CA?

Yes. New installations and structural replacements require a building permit in Grass Valley and Nevada County jurisdictions. We handle the entire permit process application, documentation, and final inspection coordination.

What is Title 24 and does my skylight need to comply?

Title 24 is California’s mandatory energy code for buildings. Skylights must meet specific Solar Heat Gain Coefficient (SHGC) and U-Factor values for your climate zone. We select compliant glass specifications and document compliance in every permit package.

How long does skylight installation take?

A standard fixed or venting skylight installation on a single-story home typically takes one full day. Multi-unit installations, custom architectural skylights, or projects requiring structural modifications may take two days. Permit processing (typically 2-4 weeks) is the longest phase of the overall timeline.

Can you replace just the glass in my existing skylight?

Yes. If the curb and frame are structurally sound, we fabricate replacement glass panels in our in-house shop to match your unit’s exact dimensions. This is significantly less expensive than a full unit replacement and eliminates the need for roofline work.

How do I know if my skylight needs repair or full replacement?

If the glass is cracked, the IGU has failed (interior fogging), or the acrylic dome is yellowed and brittle glass or unit replacement is needed. If the glass is intact but you have a leak, flashing repair is almost always the solution. We assess both scenarios during a free site visit and give you an honest recommendation.

How much does skylight installation cost in Grass Valley, CA?

A standard fixed or venting residential skylight typically ranges from $1,500–$4,500 installed, depending on unit type, glass specification, roof complexity, and permit fees. Tubular skylights are generally $500–$1,500 installed. Use our cost calculator for an instant estimate, or call for a free itemized site quote.
