Technical Reference
Understanding the components of a curb-mounted skylight helps you identify which part has failed and what type of repair is needed.
Dual-pane insulated glass unit with Low-E coating and argon gas fill for thermal performance. The spacer bar separates panes while the seal prevents gas escape.
Thermally broken aluminum or vinyl frame mounted on a wood or composite curb. The curb raises the skylight above the roof surface for proper drainage and waterproofing.
Step flashing and counter flashing create overlapping waterproof barriers between the skylight curb and the roof surface. This is the most failure-prone component.
Glass Options
The right glass selection determines your skylight's performance, safety, energy efficiency, and longevity. We help you choose the best option for your application.
Heat-treated for 4x strength. Shatters into safe pebbles instead of sharp shards. Required by code for overhead applications.
Two glass layers bonded with PVB interlayer. Holds together when broken. Best overhead safety option with UV blocking.
Dual-pane IGU with Low-E coating reflects infrared heat. Argon gas fill reduces convection. Cuts heat loss by up to 40%.
TiO2 coating uses UV light to break down organic dirt. Rain sheets off the hydrophilic surface. Ideal for hard-to-reach skylights.
Multi-layer laminated construction withstands hail, debris, and forced entry attempts. Meets hurricane and high-wind zone codes.
Diagnosis
Recognizing the problem early saves money and prevents secondary damage. Here are the most common skylight issues we diagnose and repair across the DMV.
The most frequent skylight complaint. Leaks typically originate from deteriorated flashing, cracked sealant, or improper installation.
Fog or moisture trapped between the glass layers indicates a failed insulated glass unit seal. The argon gas has escaped and humid air has entered.
Thermal stress, hail damage, falling tree branches, or age-related fatigue can crack skylight glass.
Older acrylic or polycarbonate skylight domes yellow and haze over time from UV exposure.
Skylights without Low-E coatings or tinting allow significant solar heat gain, especially on south and west-facing roofs.
Vented skylights have crank operators, chains, or motorized systems that wear out over time. Stuck-open skylights let in rain and insects.
Skylight Types
Whether you need a repair to your existing skylight or a brand-new installation, we work with every skylight configuration.
Fixed skylights are the most common and most affordable type. They do not open -- their sole purpose is to admit natural light.
Vented skylights open to allow warm, moist air to escape -- especially valuable in kitchens, bathrooms, and upper floors.
Tubular skylights -- also called sun tunnels or light tubes -- capture sunlight through a small rooftop dome and channel it through a reflective tube into.
Custom skylights are fabricated to match unique architectural requirements -- oversized spans, unusual shapes, multi-panel ridge skylights, and structural.
Why Skylights Matter
A well-maintained or newly installed skylight transforms a room. Here is what you gain when your skylights are performing at their best.
Skylights deliver up to three times more light than vertical windows of the same size.
Modern Energy Star-rated skylights with Low-E glass, argon gas fill, and thermally broken frames minimize heat loss in winter and solar heat gain in summer.
Vented skylights release warm, humid air that naturally rises to the ceiling -- the chimney effect.
Natural daylight from overhead regulates circadian rhythms, boosts mood, and increases productivity.
Well-installed skylights are a desirable home feature that boosts curb appeal and market value.
Unlike windows that require curtains or blinds for privacy, skylights provide natural overhead light without exposing the interior to neighbors or street.

Request a Free AssessmentOur Process
A systematic approach ensures we identify the root cause, use the right materials, and deliver a result that lasts for years.
We perform a thorough roof-level and interior inspection of your skylight. We check the glass condition, seal integrity, flashing, curb or deck-mount.
Based on the inspection, we explain the issue clearly and recommend repair or replacement with a detailed written estimate.
We protect your interior furnishings and flooring below the skylight. On the roof, we set up fall protection, stage materials, and ensure safe working.
For repairs: we replace failed components -- glass, seals, flashing, or operators -- using manufacturer-specified materials.
Every skylight job ends with comprehensive waterproofing verification. We water-test the entire installation, check interior and exterior seal lines.
We remove all debris, clean the glass inside and out, and walk you through the completed work.
The Expert Advantage
Skylights are where roofing meets glazing. You need a team that understands both disciplines.
We trace every leak to its source -- flashing, seals, or glass -- so we fix the real problem, not just the symptoms. No guesswork.
All replacement glass features Low-E coating and argon gas fill for superior thermal performance, UV protection, and lower energy bills.
Every skylight repair and installation meets Virginia, Maryland, and DC building codes, plus manufacturer specifications for safety and warranty coverage.
Our crews follow strict fall protection and rooftop safety protocols. We protect your roof surface, landscaping, and interior during every job.
Expert Knowledge
The DMV region presents unique challenges for skylights. Washington DC, Northern Virginia, and Maryland experience a climate that cycles between humid summers exceeding 90 degrees, freezing winters with ice and snow loads, and everything in between. This constant thermal expansion and contraction stresses every component of a skylight installation -- from the glass seals and weatherstripping to the flashing and roofing materials surrounding the unit.
UV exposure during long summer days degrades sealants and gaskets. Freeze-thaw cycles crack caulk and shift flashing. Heavy rain and occasional ice dams test waterproofing at every joint. A skylight that was properly installed twenty years ago may now have multiple failure points -- not from poor workmanship, but from the cumulative effects of two decades of mid-Atlantic weather.
At Expert Glass Repair, we understand these regional factors because we have been repairing and replacing skylights across Arlington, Alexandria, Bethesda, Silver Spring, and every community in between since 2004. Our technicians know which failure modes are most common in this climate and which repair strategies deliver the longest-lasting results.
A modern skylight is an engineered assembly of multiple components working together. The insulated glass unit (IGU) consists of two or three glass panes separated by a spacer bar and sealed with a primary and secondary sealant. The space between panes is filled with argon or krypton gas to reduce heat transfer. This glass assembly sits in an aluminum, vinyl, or wood-clad frame that provides structural support and thermal isolation.
The frame is mounted on a curb -- a raised wooden or composite structure that elevates the skylight above the roof surface. Deck-mount skylights attach directly to the roof deck without a curb, using an integrated flashing kit. In either case, a system of step flashing, counter flashing, and sealant creates the waterproof barrier between the skylight and the surrounding roof.
Each of these components can fail independently. The IGU seal can break, allowing moisture between panes (the foggy skylight problem). The weatherstripping between frame and glass can dry out, allowing air and water infiltration. The flashing can corrode, lift, or separate from the roofing material. The curb wood can rot from prolonged water exposure. Identifying the specific failure point is critical to performing the right repair -- and avoiding unnecessary replacement costs.
If your skylight was installed before 2005, it likely uses technology that is significantly less efficient than what is available today. Modern Energy Star-rated skylights feature Low-E coatings that reflect infrared heat while transmitting visible light, argon gas fill that reduces convective heat transfer, and thermally broken frames that prevent the frame itself from conducting heat or cold into your home.
Solar-powered venting skylights from manufacturers like VELUX and Fakro can open and close automatically based on temperature and humidity sensors. Rain sensors close the unit at the first sign of precipitation. Integrated blinds and shades -- also solar-powered -- allow you to control light and heat gain without reaching an overhead unit.
For homeowners in Arlington, McLean, Bethesda, and other DMV communities considering a skylight upgrade, Energy Star-rated units may qualify for the federal Residential Clean Energy Credit. The combination of energy savings, improved comfort, and available tax incentives often makes a full skylight replacement more financially attractive than repeated repairs to an aging unit.
Skylight work requires expertise in both glazing and roofing -- two trades that rarely overlap. Many roofing contractors can install flashing but do not understand glass types, Low-E coatings, or IGU construction. Many glass companies can replace a pane but are not comfortable working on a roof or diagnosing flashing failures. Expert Glass Repair bridges both disciplines.
Our technicians are trained in roof safety, fall protection, and proper rooftop work practices. They understand the building codes in Virginia, Maryland, and Washington DC that govern overhead glazing -- including requirements for tempered or laminated safety glass, minimum slope angles, and emergency egress specifications for operable skylights.
With over 20 years of service in the DMV, a VA License (), and relationships with every major skylight manufacturer, we provide honest assessments, transparent estimates, and work that is backed by both our warranty and the manufacturer's warranty. Whether you need a simple reseal on a Georgetown rowhouse skylight or a complete multi-unit replacement on a Tysons Corner office building, we have the expertise and the equipment to get the job done right.
