What Skylight Installation Involves
Skylight installation is not a simple cut-and-drop job. It requires precise framing, proper flashing integration, and insulation detailing to prevent condensation and leaks. We install fixed skylights, vented skylights with manual or solar-powered blinds, and sun tunnels for tight spaces. For vented units, we run power for the solar-blind motor and integrate remote controls. All units are flashed with a continuous curb-mounted system—no step flashing shortcuts. We seal with butyl tape and stainless steel fasteners, not caulk alone. On a typical Hillsborough split-level ranch, a single 22-by-46-inch fixed skylight takes one full day to frame, flash, and finish. A vented unit with solar blind adds another half-day for wiring.
Signs You Need Skylight Installation
You may need a new skylight if you see water stains on the ceiling below the unit, feel a draft near the window, or notice condensation between the glass panes. In Hillsborough’s humid summers, failed seals cause fogging and mildew. During winter, ice dams can back water up under old step flashing. If your skylight is more than 15 years old, the seal likely has degraded. A sun tunnel is a great option for a dark bathroom or hallway where a full skylight won’t fit.
Our Skylight Installation Process
- Site Assessment: We inspect the attic for structural clearance, insulation placement, and roof pitch. For Hillsborough homes with low-slope roofs, we verify that the curb height meets code for snow load.
- Unit Selection: We help you choose between VELUX fixed or vented models, Solatube sun tunnels, and options like solar-powered blinds or rain sensors. We match the curb size to the rough opening.
- Roof Deck Prep: We cut the opening, frame the curb with pressure-treated lumber, and install a self-adhered ice-and-water shield over the entire curb area. For steep roofs, we also install a cricket to divert water around the skylight.
- Flashing Installation: We install a continuous aluminum flashing system that integrates with your existing shingles or metal roof. No step flashing—we use a one-piece flashing pan that directs water over the shingles.
- Interior Finish: We insulate the shaft with rigid foam, install drywall and trim, and seal the interior with low-VOC caulk. For vented units, we connect the motor and test the remote.
- Final Seal & Cleanup: We apply a bead of sealant at the head flashing, sweep the roof with a magnetic nail sweeper, and remove all debris. We register your manufacturer warranty and provide a written installation report.
Cost Considerations in Hillsborough
Skylight installation costs in Hillsborough range from $950 to $2,800 per unit installed, depending on the size, type, and roof complexity. A fixed 22-by-46-inch VELUX skylight on a standard asphalt shingle roof runs about $1,400. A vented unit with solar-powered blinds adds $600 to $900. A Solatube sun tunnel for a dark hallway costs $750 to $1,100. Roof pitch, ceiling height, and the need for a shaft extension increase labor. We provide a flat-rate quote—no per-hour surprises.
Warranty & Insurance
We install VELUX skylights with a 10-year manufacturer warranty on the glass and a 20-year warranty on the flashing system. Solatube sun tunnels carry a 10-year warranty on the dome and tube. Our workmanship is backed by a 5-year installation warranty covering leaks and seal failures. We are fully insured with general liability and workers’ compensation coverage. If your skylight was damaged by a storm, we help document the damage for your insurance claim and coordinate with your adjuster.
Why Choose Hillsborough Roofing Pros for Skylight Installation in Hillsborough?
Hillsborough spans ZIP codes 08844 and 08807, with elevations from 50 to 300 feet above sea level. That variation means different snow loads and drainage patterns. We’ve installed skylights in mid-century ranches in Country Club Estates, newer colonials in Hillsborough Village, and historic farmhouses near Neshanic Station. We know the local building codes and the common roof pitches in neighborhoods like Clover Hill and Blackpoint. Heavy snow and ice dam risks in winter, plus frequent thunderstorms with hail in spring and summer, demand flashing details that hold up. We don’t cut corners—we build skylights that last through Hillsborough’s weather.
Signs You Need Skylight Installation
Leaking After Heavy Rain
If you see water stains on the ceiling after a thunderstorm, the skylight seal has likely failed. Hillsborough’s frequent spring storms put old step flashing to the test.
Foggy or Cloudy Glass
Condensation between the glass panes means the sealed unit has lost its gas fill. This reduces insulation and lets UV rays fade your furniture.
Draft Around the Unit
Feeling cold air near the skylight in winter? The curb seal or insulation has degraded. Ice dams can worsen this by forcing water under the flashing.
Water Stains on Ceiling
Yellow or brown rings below the skylight indicate a slow leak. Over time, this can rot the framing and attract mold in humid Hillsborough summers.
Skylight Won't Open or Close
Manual crank mechanisms rust and fail. A vented skylight that sticks open can let in rain and pests. Solar-powered blinds can replace the old motor.
Dark Rooms Need Natural Light
If your hallway, bathroom, or stairwell feels like a cave, a sun tunnel or fixed skylight can add daylight without major structural work.
