Skylight Installation in Nashville, TN
Bringing natural light into your Nashville home starts with a skylight installation that’s built to last. At Nashville Roof Master, we’ve installed over 400 skylights across Middle Tennessee since 2005, using only weather-tight flashing and energy-efficient glass. Our team handles every step from roof cut to interior finish, so you get a brighter space without a single leak.

Skylight installation means cutting an opening in your existing roof, framing it, setting a glazed window unit, and sealing everything with flashing to keep water out. It’s not a simple window job—your roof’s pitch, decking material, and local Nashville weather all dictate the right approach. We install both fixed and venting skylights, with options like low-E glass, solar-powered blinds, and impact-rated models for hail season.
Materials and Methods We Use
We primarily install Velux and Fakro units because their flashing kits integrate with asphalt shingles, metal roofs, and standing seam profiles common in Nashville. For a typical homeowner, we recommend double-pane, argon-filled glass with a U-factor below 0.30. Every skylight gets a continuous curb—a raised frame that sheds water—rather than a flush mount, which fails faster in our freeze-thaw cycles. Our flashing is always 26-gauge aluminum or copper, never thin galvanized steel that rusts within five years.
How Much Does Skylight Installation Cost in Nashville?
For a standard 22-by-46-inch fixed skylight on a shingle roof, expect $1,200 to $2,800 installed. A venting skylight with a remote control runs $2,400 to $4,200. Add $400 to $800 if your roofer needs to reframe rafters or replace rotted decking—common in older Nashville homes built before 1980. We provide a written estimate after measuring your attic’s rafter spacing and checking for ductwork or wiring in the way.
Signs You Need a New Skylight
If your existing skylight shows condensation between panes, has cracked seals, or you see water stains on the ceiling below, it’s time for replacement. Nashville’s humidity accelerates seal failure, and our summer hailstorms often crack older acrylic domes. Even if the glass looks fine, a skylight installed before 2005 likely lacks low-E coating, letting in UV rays that fade your furniture and drive up cooling bills.
Our Step-by-Step Skylight Installation Process
- Interior and Exterior Inspection: We check your attic for rafter spacing, insulation, and any electrical lines. On the roof, we verify the slope and mark the cut location to avoid vents or chimneys.
- Roof Cut and Framing: We remove shingles in a 4-foot square area, cut the decking with a saw set to 1-inch depth, and install a doubled-up frame of pressure-treated lumber to support the skylight’s weight.
- Flashing and Underlayment: We apply ice-and-water shield around the curb, then install step flashing interwoven with your shingles. For metal roofs, we use a custom-fabricated saddle flashing that matches the panel profile.
- Skylight Installation and Sealing: The unit is set on the curb, leveled, and screwed into the frame. We seal every screw head with butyl tape and install a counter-flashing cap.
- Interior Finish and Drywall: We frame a light shaft from the skylight down to your ceiling, insulate the shaft, and tape/mud drywall. We leave the final paint to your preferred painter.
- Final Leak Test: We simulate a 3-inch-per-hour rain with a hose for 20 minutes while you watch the interior. No drips means we’re done.
Warranty and Insurance Details
Every skylight we install carries a 10-year manufacturer warranty on the glass and seals. Nashville Roof Master backs our workmanship with a 5-year leak-free guarantee—if the skylight leaks from improper installation, we fix it at no cost. Our liability insurance covers any accidental damage to your roof or interior during the job. We’re licensed in Tennessee (License #98765) and carry workers’ comp for our crew.
Nashville Climate Considerations
Nashville averages 50 inches of rain and 5-6 hailstorms per year. That means your skylight’s flashing must handle heavy runoff and impact. We use only Class 4 impact-rated glass on south-facing slopes, where hail hits hardest. For venting skylights, we recommend models with a rain sensor that closes automatically—our humid summers can turn a 10-minute shower into a soaked floor. Also, Nashville’s clay soil causes foundation shifts; we account for this by leaving a 1/8-inch expansion gap around the curb to prevent frame warping.
Why Choose Nashville Roof Master for Skylight Installation
We’ve been cutting roofs in Nashville since 2005, and we know which neighborhoods have old-growth rafters (12-inch centers in Green Hills) versus modern trusses (24-inch centers in Antioch). That experience means no surprises when we open your decking. We also coordinate with your interior contractor if you’re combining skylight installation with a kitchen or bath remodel.

Our Skylight Installation Process
- On-Site Roof and Attic Inspection: We measure your roof’s pitch, identify rafter spacing (typically 16 or 24 inches), and check for ducts or wiring in the planned cut area. This takes about 45 minutes.
- Cut and Frame the Opening: We strip shingles, cut the decking, and install a doubled 2x8 curb frame, ensuring it’s level and square. This step takes 2-3 hours for a single skylight.
- Install Flashing and Underlayment: We apply ice-and-water shield, then install step flashing or custom metal flashing. For asphalt shingles, we interweave each piece with the existing shingle course. Time: 2 hours.
- Set and Seal the Skylight: The unit is placed on the curb, screwed into place, and sealed with butyl tape at every fastener. We install the counter-flashing cap and test with a hose. Time: 1.5 hours.
- Frame and Insulate the Light Shaft: We build a drywall-ready shaft from 2x4 studs, insulate with R-19 batts, and install a vapor barrier. This step takes 2-3 hours depending on ceiling height.
- Final Walk-Through and Cleanup: We show you the finished interior, explain how to operate venting skylights, and remove all debris. We use a magnetic roller to pick up any stray nails from your yard.
Signs You Need Skylight Installation
6 Signs Your Nashville Home Needs a New Skylight
- Condensation between panes – Failed seals let moisture in, reducing energy efficiency and causing fogging.
- Water stains on ceiling below – A leaking skylight can rot drywall and attract mold, especially in Nashville’s humid climate.
- Visible cracks or chips in the glass – Nashville hailstorms frequently damage older acrylic or single-pane domes.
- Drafty room near the skylight – Poor insulation or aging frames allow heat to escape in winter and cool air to leak in summer.
- UV-faded furniture or flooring – Skylights installed before 2005 often lack low-E coating, letting in damaging UV rays.
- Skylight is more than 20 years old – Older units have less efficient glass and outdated flashing that’s prone to failure in freeze-thaw cycles.
