Skylight Types

Skylights We Install & Repair

From compact tubular daylighting systems to large custom commercial skylights, we install every type of skylight to bring natural light into your space.

Fixed Skylights

Non-opening skylights designed to bring maximum natural light into interior spaces.

  • Maximum natural light penetration
  • No moving parts -- lowest maintenance
  • Best thermal performance and seal integrity
  • Available in custom sizes and shapes
  • Ideal for vaulted ceilings and cathedral spaces

Vented Skylights

Operable skylights that open to allow fresh air circulation in addition to natural light.

  • Fresh air ventilation reduces moisture buildup

  • Rain sensors auto-close during storms
  • Integrated insect screens included
  • Ideal for kitchens, bathrooms, and lofts

Tubular Skylights

Compact, tube-based systems that channel sunlight from the roof through a reflective tube into interior rooms.

  • Fits between standard 16-inch rafter spacing
  • No structural roof modifications required
  • Highly reflective tube delivers bright light
  • Works in closets, hallways, and bathrooms
  • Fastest installation -- often completed in hours

Custom & Commercial Skylights

Large-format and architecturally designed skylight systems for commercial buildings, atriums, and custom residential projects.

  • Engineered for commercial structural loads

  • Thermally broken aluminum frames
  • Impact-rated glass options available
  • Designed to meet commercial energy codes

Benefits

Why Install a Skylight?

Natural Daylight

Skylights deliver up to three times more light than vertical windows of the same size. They illuminate deep interior spaces that wall windows cannot reach, reducing reliance on electric lighting throughout the day.

Energy Savings

Reduced electric lighting costs and passive solar heating in winter offset energy use. Modern low-E skylights minimize summer heat gain while maximizing winter solar gain for year-round efficiency.

Ventilation

Vented skylights exhaust warm, moist air that naturally rises to the ceiling. This stack-effect ventilation reduces cooling loads and helps control humidity in kitchens, bathrooms, and upper floors.

Health & Wellbeing

Exposure to natural daylight improves mood, sleep quality, and productivity. Skylights bring biophilic design into your home, connecting interior spaces with the sky and natural light cycles.

Home Value

Skylights are a high-value improvement that enhances both the aesthetics and functionality of a home. They are a distinguishing feature in real estate listings and appeal strongly to buyers in the DMV market.

Architectural Character

Skylights add dramatic visual interest to rooms by creating dynamic patterns of light and shadow that change throughout the day. They transform ordinary ceilings into a connection point with the outdoors.

Repair & Replacement

Skylight Repair Services

Existing skylights need attention too. We diagnose and fix every common skylight problem, from failed seals to cracked glass to leaking flashing.

Glass Replacement

Cracked, chipped, or hazy skylight glass replaced with new energy-efficient double-pane or triple-pane glass. We match existing frame dimensions for a seamless fit.

Seal & Gasket Repair

Failed seals cause condensation between glass panes. We replace the insulated glass unit and reseal the frame to restore clarity and thermal performance.

Flashing Repair

Leaking skylights are almost always a flashing problem. We remove old flashing, install new step and counter flashing, and integrate with existing roofing materials.

Frame Restoration

Wood, aluminum, or vinyl frames that are rotted, corroded, or warped are repaired or replaced. We match existing profiles or upgrade to modern low-maintenance materials.

Operator Mechanism Repair

Vented skylights with broken cranks, failed motors, or stuck chains are repaired or upgraded. We service manual, electric, and solar-powered opening systems.

Full Unit Replacement

When repair is not cost-effective, we replace the entire skylight unit including frame, glass, and flashing. Modern replacements are more energy efficient and easier to maintain.

How We Work

Our Installation Process

01

Roof Assessment

We inspect your roof structure, rafter spacing, and attic conditions. We identify the optimal placement for maximum light, discuss skylight size and type,

02

Design & Selection

We help you choose the right skylight type, size, and glazing options based on your goals, roof pitch, orientation, and energy requirements.

03

Installation

Our team cuts the roof opening, builds or modifies the curb framing, installs the skylight with manufacturer-specified flashing,

04

Final Inspection

We test the skylight operation (for vented models), verify the flashing and seal integrity, clean the glass,

Glass Options

Skylight Glazing Technologies

Low-E Coated Glass

Microscopically thin metallic coatings reflect infrared heat while transmitting visible light, significantly improving your skylight's energy performance.

Argon Gas Filled

The space between double-pane glass is filled with argon gas instead of air. Argon is denser than air and conducts less heat,

Laminated Safety Glass

Two layers of glass bonded to a plastic interlayer. If broken, the glass fragments adhere to the interlayer instead of falling.

Impact-Resistant Glass

Designed to withstand hail, wind-borne debris, and heavy snow loads. Impact-rated skylights meet the stringent standards required in hurricane zones and are ...

Design Guidance

Skylight Placement Guide

Where you place a skylight matters as much as which skylight you choose. Orientation, room function, and roof structure all influence the optimal location.

North-Facing Skylights

Provide consistent, even daylight throughout the day without direct sun glare or excessive heat gain. Ideal for studios, offices, and rooms where uniform natural light is desired. The preferred orientation for reducing summer cooling loads in the DMV climate.

South-Facing Skylights

Maximize solar heat gain in winter, contributing to passive heating. In summer, low-E coatings and blinds control excess heat. Best for living rooms and great rooms in homes where winter warmth is welcome. Pair with vented models to exhaust summer heat.

East & West-Facing Skylights

East-facing skylights bring bright morning light, ideal for kitchens and breakfast nooks. West-facing skylights capture afternoon sun but may require shading in summer. Consider external blinds or heat-rejecting glass for west-facing installations.

Kitchens & Bathrooms

Vented skylights are strongly recommended for kitchens and bathrooms to exhaust moisture, cooking odors, and heat. The natural stack effect draws warm, humid air up and out through the open skylight, reducing the need for mechanical ventilation.

Hallways & Stairwells

Interior hallways and stairwells benefit dramatically from skylights because they cannot have wall windows. A single skylight or tubular daylighting system can illuminate an entire hallway, eliminating the need for daytime electric lighting.

Vaulted Ceilings

Skylights in vaulted or cathedral ceilings require no light shaft -- the skylight opens directly into the room. This produces the most dramatic effect, with a direct view of the sky and maximum light penetration into the space below.

Our Commitment

Why Choose Expert Glass Repair

Manufacturer-Certified Installers

Our skylight installers are trained and certified by leading manufacturers. Proper installation is the single most important factor in skylight performance, and certification ensures we follow the exact procedures that maintain your manufacturer warranty.

We handle every aspect of the project from initial assessment through final inspection. If permits are required, we prepare the applications and drawings. If structural modifications are needed, we coordinate with licensed engineers. One contractor, one point of contact, one warranty.

Common Questions

Skylight FAQ

How long does skylight installation take?
A standard skylight installation takes 1 to 2 days for most residential projects. This includes cutting the roof opening, framing the curb, installing the skylight unit, flashing, and interior finishing. Complex installations involving structural modifications or light shafts may take 2 to 4 days.
Will a skylight cause my roof to leak?
A properly installed skylight does not leak. Leaks are caused by improper flashing, deteriorated seals, or incorrect installation. We use manufacturer-specified flashing kits and follow roofing best practices to ensure a watertight seal that lasts the life of the skylight.
What is the difference between fixed and vented skylights?
Fixed skylights do not open and are designed solely to bring natural light into a space. Vented skylights can be opened to allow air circulation, which helps with moisture control in kitchens and bathrooms. Vented models are available in manual crank, electric, and solar-powered options.
Are skylights energy efficient?
Modern skylights with low-E coatings, argon gas fill, and insulated frames achieve excellent energy ratings. They reduce the need for electric lighting during daytime hours and, when properly placed, can contribute to passive solar heating in winter. Vented skylights also reduce cooling costs by venting hot air.
Can you replace the glass in an existing skylight?
Yes. If the skylight frame and flashing are in good condition, we can replace just the glass pane. This is common when the seal has failed causing fogging between panes, or when upgrading from single-pane to double-pane glass. A glass-only replacement is faster and more affordable than a full unit replacement.
Do skylights work on flat roofs?
Yes. Flat-roof skylights are mounted on a raised curb to ensure proper water drainage. We install both fixed and operable flat-roof skylights using specialized flashing and membrane integration techniques designed for low-slope roofing systems commonly found on commercial buildings and modern homes.
How do I know if my skylight needs to be replaced?
Signs that a skylight needs replacement include persistent condensation between glass panes (seal failure), visible cracks or chips in the glass, water stains on the interior frame or ceiling, difficulty opening a vented skylight, and yellowing or hazing of acrylic dome skylights. Skylights typically last 15 to 25 years.
