Skylight Specialists

Light done right, sealed for good.

A skylight transforms a dark room — more natural light, better ventilation, a view of the sky, and real added value to your home. Done right, it does all that for decades without a single drop of water getting in.

Done wrong, it's the most notorious leak source on a roof. The difference is entirely in the flashing. We're roofers, not handymen with a saw — we install the full metal flashing kit, wrap the opening in ice-and-water membrane, and weave the shingles back in so the skylight sheds water like the rest of the roof.

Fixed, vented, solar-powered, or a sun tunnel for an interior room — we'll match the type to your space and finish the interior shaft so it looks built-in. The ideal time to add one is during a roof replacement, but we install into existing roofs every week.

How We Build It

Anatomy of a leak-proof skylight.

A skylight is a penetration through your roof — the only thing standing between daylight and a leak is how it's flashed and sealed. Here's exactly how we make it watertight.

Skylight detail · flashing & seal
Build Spec · Six non-negotiables
01

Curb & mounting

The skylight is set on a properly built and leveled curb — the foundation that keeps the unit square and the glass sealed for decades.

02

Step & head flashing

A real metal flashing kit — step flashing up the sides, head flashing above, apron below — not a bead of caulk. This is the single thing that decides whether a skylight ever leaks.

03

Ice & water underlayment

Self-adhering membrane wrapped around the opening and lapped under the flashing — a second waterproof layer where the roof is most vulnerable.

04

Insulated Low-E glass

Dual-pane, Low-E glazing that blocks UV and cuts heat transfer — natural light without the summer heat gain or winter cold spot.

05

Interior light shaft

A finished, often-flared shaft that spreads the light into the room — drywalled and painted to look built-in, not bolted on.

06

Weather-tight seal

Every joint sealed and shingled back in so water sheds over the unit and down the roof — the skylight becomes part of the roof, not a hole in it.

Skylight Options

Types of skylights we install.

From a simple fixed unit that floods a room with light to solar-powered vented models and sun tunnels — the right type for every space.

Fixed / Deck-Mounted

Most Light

A sealed, non-opening skylight that maximizes natural light — the most popular and most economical choice for brightening a room.

Ventilating Skylights

Fresh Air

Open to release heat and humidity — ideal over kitchens and bathrooms where ventilation matters as much as light.

Solar-Powered Vented

No Wiring

Opens and closes on a solar-charged motor with a rain sensor — the convenience of a vented skylight with no electrician required.

Sun Tunnels (Tubular)

Tight Spaces

A reflective tube that channels daylight into hallways, closets, and small interior rooms a full skylight can't reach.

Curb-Mounted

Low-Slope

Set on a raised curb for low-slope roofs and larger units — the right mount where a deck-mounted skylight won't shed water.

Low-E Glass Upgrades

Efficiency

Energy-efficient glazing options that cut heat gain and UV — light and views without the energy penalty.

Our Services

Complete skylight services.

New installs, replacements, leak repair, and sun tunnels — everything that brings light in and keeps water out.

01

New Skylight Installation

We cut, frame, flash, and finish the opening — a complete install, inside and out, that becomes a watertight part of your roof.
02

Skylight Replacement

Swap an old, foggy, or leaking unit for a modern energy-efficient skylight — new flashing and seal included, not reused.
03

Re-Flashing & Leak Repair

Skylight leaking? Almost always the flashing, not the glass. We strip and rebuild the flashing kit to stop it for good.
04

Sun Tunnel Installation

Bring daylight to interior rooms with no exterior wall — a tubular skylight threaded from the roof down through the attic.
05

Solar & Vented Skylights

Fresh-air and solar-powered models installed and sealed — ventilation and light in one opening.
06

Skylight + Roof Combos

Adding skylights during a roof replacement is the ideal time — one crew, one flashing job, one warranty.
Free Estimate

Bring in the light — without the leak.

A free consultation, honest guidance on the right type and placement, and flashing done the way only a roofer does it.

Our Process

How a skylight install works.

Five steps from consultation to a finished, watertight skylight and a bright new room — most singles wrap in a day.

01

Consultation

We assess your roof, attic, and the room below, and recommend the right type, size, and placement for the light you want.

02

Product Selection

Choose your unit — fixed, vented, solar, or tubular — and glazing options, with energy-efficient upgrades laid out.

03

Opening & Framing

We cut and frame the opening to spec, reinforcing the rafters and prepping the deck around it.

04

Install & Flash

The unit is set, the full metal flashing kit installed, ice-and-water membrane wrapped, and shingles woven back in.

05

Interior Finish

We finish the light shaft — drywall, trim, and paint — so it looks built-in, then clean up completely.

By The Numbers

42 years. One standard.

The kind of track record that only comes from doing it right, in the same communities, for a very long time.

Since 1984

“A skylight only leaks when someone treated it like a window instead of a hole in the roof. Flash it like a roofer, and it's watertight for the life of the roof.”

Family-run since 1984. We install skylights the way we build roofs — full metal flashing, ice-and-water membrane, shingles woven back in — so the light comes in and the water never does.

The Reasonable Difference

Why homeowners choose us.

Roofer-grade flashing, quality energy-efficient units, and 42 years of keeping Michigan roofs watertight.

Flashing Done Right

Skylights leak for exactly one reason: bad flashing. We install the full metal flashing kit and wrap the opening in ice-and-water membrane — the watertight detail handymen skip.

Roofers, Not Handymen

A skylight is a hole in your roof. We're roofers — we make it a watertight part of the system, with the same care we put into the roof around it.

Quality Units

Energy-efficient, Low-E glazing from name-brand skylight manufacturers — built to stay clear, sealed, and leak-free for decades.

Energy-Smart Glazing

Dual-pane Low-E glass brings in the light without the summer heat gain or the winter cold spot — comfort, not just brightness.

42 Years in Michigan

Family-run since 1984. We know how Michigan weather tests a roof penetration — and how to flash one so it never becomes a problem.

Workmanship Warranty

Every skylight install is backed by our workmanship warranty. If it ever leaks because of our work, we come back and fix it at no charge.

Skylight Installation FAQ

Skylight FAQs.

Properly installed skylights don't. Nearly every leaking skylight was flashed with caulk instead of a real metal flashing kit, or installed without ice-and-water membrane around the opening. We install both — which is why our skylights stay watertight.
Most residential skylight installs run $1,200–3,500 per unit installed, depending on type, size, glazing, and the interior finish work. Solar-vented and larger units cost more. We provide free written estimates with exact pricing.
It depends on the room. Fixed deck-mounted units give the most light for the money; vented or solar-vented models are ideal over kitchens and baths; sun tunnels bring daylight to interior spaces a full skylight can't reach. We'll match the type to your goal.
Modern skylights with dual-pane Low-E glazing are — they bring in daylight (cutting lighting use) while blocking UV and limiting heat transfer. The efficiency depends on the glass and the quality of the install seal, both of which we handle.
Yes — we cut, frame, flash, and finish the opening on an existing roof. The ideal time is during a roof replacement, when the flashing integrates cleanly, but we install into existing roofs routinely.
Fixed units cost less and give maximum light with no moving parts. Vented (especially solar-powered) units add fresh-air ventilation — worth it over kitchens, bathrooms, and any room that traps heat or humidity.
