What Skylight Installation Involves

A skylight requires careful removal of roofing material—asphalt shingles, three-tab shingles, architectural shingles, cedar shakes, slate, or tile—plus the sheathing (plywood or OSB) and existing underlayment.

We frame an opening in the roof deck and install the skylight unit (fixed skylights for views, vented skylights for ventilation, or sun tunnels for diffused light).

Step flashing and counter-flashing seal where the skylight meets the roofline. Ice-and-water shield, synthetic underlayment, and roofing felt create the weatherproof barrier.

Sealant and roof cement secure all seams and fasteners. Finally, we restore shingles, drip edge, soffit trim, and fascia so your rooftop is protected and finished.

Materials: Skylight unit (VELUX, Solatube), flashing kit (step, counter, boot, apron flashing), underlayment and ice-and-water shield, roofing felt, sealant and caulk, fasteners, insulation for the frame, matching shingles (asphalt, three-tab, architectural, wood shake, cedar, slate, or tile as needed).

When to Install a Skylight

Many Hillsborough homeowners notice dark attic spaces and eaves in mid-century ranches and split-levels. A skylight brings natural light, reduces daytime electricity use, and improves insulation value through energy-efficient models.

Vented skylights add attic ventilation, managing humid summer conditions and preventing moisture that promotes algae and moss growth. If your roof deck can support the opening and has adequate pitch (south- or east-facing is ideal), a skylight works well.

Combined with proper gutter and downspout drainage, correct flashing, ice-and-water shield, and counter-flashing handle Hillsborough's heavy snow and ice dam risks.

Our Skylight Installation Process

Inspection & Design – We inspect your roof deck, roof pitch, rafters, joists, and attic structure. We check sheathing (plywood or OSB) condition and discuss fixed skylights, vented skylights, or sun tunnels.
Permits & Materials – We pull Hillsborough building permits and order the skylight unit, flashing kit (step flashing, counter-flashing, boot flashing, apron flashing), underlayment, ice-and-water shield, roofing felt, and matching shingles. Insulation wrap is included for the frame.
Roof Opening – We remove existing shingles, cut through the roof deck and sheathing, and frame the opening with rafters or joists. Debris goes into a dumpster.
Flashing Installation – Flashing is sealed with sealant, caulk, and roof cement. Ice-and-water shield is applied under flashing—this is the critical weatherproofing step.
Skylight Unit Installation – The unit is secured and fastened per manufacturer specs (VELUX, Solatube, etc.), with insulation frame installed.
Roof Restoration – Shingles are reinstalled with ring-shank nails. Drip edge, soffit, and fascia trim restore the roofline and eaves.
Final Inspection – We verify all flashing, underlayment, waterproofing, and insulation. Debris is cleared; the site receives a magnetic nail sweep.

Typical timeline: 2–4 days depending on roof complexity and weather.

Cost Considerations in Hillsborough

Skylight installation typically costs $1,200–$3,500 per unit, depending on type and roof complexity. Fixed skylights cost less than vented models; sun tunnels fall in the mid-range.

Labor comprises roughly 60% of the cost. Steeper roofs (gambrel or mansard styles in some Hillsborough homes) take longer. Winter installations are complex due to ice dams and snow loads.

We provide a written roof estimate before starting, including permit fees. Many homeowners recover the cost within 5–10 years through energy savings, especially with vented skylights that improve insulation value and attic ventilation.

Warranty & Insurance

VELUX and Solatube skylights include 10-year manufacturer warranties covering unit defects. Our workmanship warranty covers flashing, underlayment, sealant, and installation.

For insurance claims due to storm or hail damage, we assist with documentation, photography, detailed roof estimates, and adjuster coordination.

Signs You Need Skylight Installation

⚠

Dark Attic or Upper Rooms

Many mid-century Hillsborough homes have dark attics and second-story rooms without windows. A skylight brings natural light and reduces your daytime electricity dependence.

⚠

Poor Attic Ventilation

Humid summers and heavy snow loads create moisture buildup in unventilated attics. Vented skylights improve airflow and prevent the algae and moss growth common on poorly ventilated roofs.

⚠

High Summer Cooling Costs

Insufficient daylighting in upper rooms means more AC use. Skylights with proper insulation reduce daytime cooling loads and lower your energy bills.

⚠

Musty or Moldy Attics

Moisture stagnation from inadequate ventilation fosters mold growth. Vented skylights allow warm, humid air to escape, addressing the root cause of attic moisture problems.

⚠

Visible Roof Damage

If the roof area where you'd install a skylight shows granule loss, curling shingles, or deteriorated flashing, the roof deck and underlayment may need inspection first.

⚠

Room Addition or Conversion

Daylighting an attic conversion, bonus room, or renovation makes the space feel larger and more valuable. A well-installed skylight requires proper frame insulation and flashing for success.
