Skylight Installation in Nashville, TN

Skylight installation starts with your roof, not your ceiling

Most homeowners call because a room feels dark. We start at the roof deck, not the ceiling, and check whether the sheathing can carry a new opening. Skylight installation rebuilds the waterproofing around that opening so water never finds a path inside.

• Building code in Tennessee sets minimum curb height and headroom, so we measure twice before anyone cuts.
• Step flashing and counter-flashing are the two layers that keep the unit from leaking where it meets the shingle field.
• An ice-and-water shield goes under the flashing line on north slopes, where ice dams form after a Middle Tennessee freeze.
• Synthetic underlayment replaces the old roofing felt or tar paper we still find under shingles on older homes.
• Roof cement and mastic get a thin bead at each corner, and both are tar and bitumen based and stay flexible in heat.

Skylight installation materials we install on Nashville rooftops

A unit is only as good as the curb, gasket, and flashing kit bolted to it. We fit VELUX and Solatube products most often, and we match the kit to your covering instead of forcing one size onto every roof.

• Fixed skylights are sealed with no moving parts, which is why they cost less and fail less often.
• Vented skylights open by hand or by motor, useful when a bath or kitchen traps humid air in July.
• Solar-powered blinds run on a small panel and cut summer heat gain without new wiring in the wall.
• Sun tunnels move daylight into a hallway or closet where a full unit will not fit.
• Curb-mounted units sit on a framed wooden curb, while deck-mounted units sit lower and suit a shallow roof pitch.
• A low-E coating on the glass slows UV fade on flooring and furniture.

Where the roofline is visible from the street, we set the unit on the back slope so the front elevation stays clean. Design consultation happens in the room, not in the driveway.

Skylight installation on shingle, metal, tile, and flat roofs

Your covering decides which flashing kit we order and how long the day runs. Shingle is quickest. Tile and slate take longer because every piece we lift has to go back where it came from.

• Asphalt shingle roofs, including architectural shingle and three-tab shingle, take a standard kit and a fresh field course around the curb.
• Wood shake and cedar shake need a wider flashing apron because the shake edges sit uneven and hold water at the corners.
• Slate, clay tile, and concrete tile are brittle, so we walk on battens and counterbattens and lift pieces with a hook instead of prying.
• Metal panel and standing-seam panel roofs need a curb spaced to the ribs so fasteners land on a purlin or solid decking.
• Corrugated panel is thinner, so we back every screw with a gasketed washer to stop overdriven fasteners.
• Membrane roofs including TPO, EPDM, and PVC membrane get a curb wrapped and heat-welded or adhesive-welded, never nailed through.
• Built-up roof and modified bitumen surfaces get a new base ply and a granulated cap sheet lapped up the curb.

Skylight installation changes the roof around it, so we check decking, edges, and drainage

Cutting an opening touches more than the unit. Here is what we inspect and rebuild on every job, because a skylight only stays waterproof when the roof around it is sound.

• Decking and substrate: we probe the plywood or OSB sheathing with a pry bar and replace any board that has gone soft.
• Framing: the opening lands on a rafter, truss bay, or ridge beam, and we add blocking so the curb cannot settle or sag.
• Edges and drainage: drip edge at the eave, fresh gutter and downspout seals, and a clear run to the valley.
• Roofline parts: the rake, ridge, ridge cap, ridge vent, hip, gable, and verge all get checked while we are already up there.
• Details that need their own flashing: a dormer, parapet, chimney, scupper, or coping on a flat section.
• Roof shapes: mansard, gambrel, and steep gable roofs change where a curb can sit and how we stage the work.
• A canopy, awning, or deep overhang above the unit shades it, which cuts heat gain and daylight both.

We bring a roofing square and chalk line for the curb, a nail gun and air compressor for the shingle work, and a roofing shovel and pry bar for the old unit.

Small penetrations matter too. Pipe flashing and a pipe boot, or a vent boot on a plumbing stack, sit within a few feet of most skylights. A failed apron flashing or boot flashing reads as a skylight leak on your ceiling.

We reseal the chimney flashing, caulk the soffit and fascia transitions, and recheck the weatherproofing at every seam before we call the job done.

Skylight installation cost: what actually moves the number

Two similar units can price far apart, and the glass is rarely the biggest line. Labor, framing, and the flashing kit decide the total, so we quote from a roof inspection instead of a phone guess.

• Unit size and glazing: a fixed unit costs less than a vented one with a motor and solar-powered blinds.
• Curb construction: new framing and blocking cost more than resetting a unit on an existing curb.
• Roofing materials: lifting and resetting concrete tile or standing-seam panel takes longer than asphalt shingle.
• Interior finish: drywall patching, trim, and paint on the ceiling below are separate from the roof work.
• Access: a steep pitch, a third-story eave, or a tight side yard means more scaffold and a slower day.

Every bid is a line-item estimate, so you can see materials, labor, and disposal apart. Financing is available, and we will walk you through the monthly numbers before you sign anything.

If the surrounding shingles show granule loss or end-of-life wear, a roof replacement quote may make more sense than a patch. We will tell you which one.

Skylight installation, step by step, from roof inspection to final seal

A skylight leaks because of the flashing, not the glass. Our process is built around that one fact, and it starts before anyone climbs a ladder.

1. Design consultation: we sit in the room, check sun angle and ceiling framing, and agree on size and placement.
2. Roof inspection and estimate: we check pitch, decking, and soft spots, then hand you a written line-item price.
3. Site protection: drop cloths inside, a dumpster at the curb, and a staged ladder, scaffold, and safety harness outside.
4. Framing and cut: we cut the opening, square the curb, and block the truss or rafter bay so nothing moves.
5. Flashing and waterproofing: step flashing, counter-flashing, an ice-and-water shield, and a fresh field course of shingle go around the curb.
6. Seal and walk-through: we caulk the exterior joints, seal the interior trim, and finish with a documented roof inspection.

Most single-unit jobs take one day on shingle and two on tile or metal. If a storm hits mid-job, we stop, tarp, and return when it is safe to be on a wet roof.

Skylight installation leaks, ice dams, and insurance claims

Old units rarely fail all at once. Sealant dries and cracks, water wicks under the flashing, and the first clue is a stain on a ceiling two rooms away.

• An ice dam pushes meltwater sideways under the flashing, so we add an ice-and-water shield and a snow guard above the curb.
• Granule loss and end-of-life wear on nearby shingles usually mean the whole area gets reworked, not resealed.
• Rot, decay, and a soft roof deck show up when we pull the unit and probe with a pry bar.
• Mold or peeling paint on the shaft points to insulation and ventilation problems, not the glass.
• Storm damage from hail or wind is often covered, and we document the storm date and photograph everything for the adjuster.

Maintenance is simple: rinse the glass twice a year, check the sealant line each fall, and keep the gutter clear so water never backs up under the eave.

Daylighting also cuts how much electricity you burn midday, which is the simplest sustainability win in a house. We can talk through green roofing options if that matters to you.

Skylight installation questions Nashville homeowners ask us

These are the questions we hear most on estimates, answered the same way we would answer them at your kitchen table.

How long does skylight installation take?

Skylight installation for one unit usually takes a single day on an asphalt shingle roof and two days on tile, slate, or standing-seam metal. Interior trim and paint can add another day.

Will skylight installation leak later?

Skylight installation leaks almost always trace back to flashing that was nailed through instead of lapped. We use step flashing, counter-flashing, and an ice-and-water shield, and every layer is lapped so water runs over the joint, not into it.

Does skylight installation work in cold weather?

Skylight installation can happen in cold weather, but we avoid it during an active freeze or a heavy snow load. Adhesive and sealant need a dry surface and a reasonable temperature to cure correctly.

Can skylight installation be done on a flat roof?

Skylight installation on a flat or low-slope roof needs a taller curb and a membrane detail, usually TPO or modified bitumen. Ponding water is the enemy there, so we check drainage before we quote.

How do I choose a roofing contractor for this work?

Choose a licensed and insured roofing contractor who shows you the flashing plan before the price. Ask what happens if the old decking is soft, and get that answer in writing on the roof estimate.

A roofer who has never flashed a skylight will leave you chasing a leak, so ask how many the crew has installed. We are happy to show you photos from recent work in the area.
