Adding Skylights During Roof Replacement: What Actually Works in Richmond

You're replacing your roof anyway. Deck's exposed, shingles are off, crew's already here.

Now's the time to add that skylight you've been thinking about, right?

Sometimes yes. Sometimes no. Here's what you need to know.

Why Roof Replacement is the Best Time for Skylights

You're already paying for the tear-off. Installing a skylight on an existing roof means removing shingles, cutting the opening, flashing it, then patching the shingles back. During a replacement, the shingles are already gone.

Saves labor costs. Installing during replacement costs $300-500 less per skylight than adding one to a finished roof.

Fresh flashing. Skylights live or die by their flashing. New roof, new flashing, everything sealed correctly from day one.

See the decking condition. Before cutting a hole, we can inspect the framing and decking. Better to find out you need a header or additional support before the skylight shows up.

One permit, one inspection. Henrico and Chesterfield require permits for roof replacements and for structural modifications like skylights. Doing both together means one permit process instead of two.

What Skylights Actually Cost in Richmond

Fixed (non-opening) skylights:

• Material: $300-600 for a quality unit (Velux, Sun-Tek)
• Installation during roof replacement: $800-1,200 total
• Installation on existing roof: $1,200-1,800 total

Venting (opening) skylights:

• Material: $500-900
• Installation during replacement: $1,000-1,500
• Installation on existing roof: $1,500-2,200

Solar-powered venting skylights:

• Material: $800-1,400
• Installation during replacement: $1,400-2,000
• Installation on existing roof: $2,000-2,800

Tubular skylights (Sun Tunnels):

• Material: $300-500
• Installation: $600-900 (same whether during replacement or after)

That's per skylight. Add two to your master bedroom and you're looking at $2,000-3,000 total.

What's Involved in Installation

More than you think.

1. Structural Framing

You're cutting a hole through your roof. That means cutting through rafters or trusses.

If you're cutting one rafter: We install headers and trimmers (support beams) to transfer the load around the opening. Adds $200-400 in materials and labor.

If you're cutting trusses: More complicated. Trusses are engineered as a complete unit. Cutting one requires either an engineered solution (expensive) or positioning the skylight between trusses (limits your placement options). Sometimes means hiring a structural engineer to approve the modification. Add $400-800 if engineering is required.

Most Richmond homes built after 1970 use trusses. That limits where you can realistically put a skylight without major expense.

2. Cutting the Roof Opening

After framing, we cut through the decking and shingles from the outside. Then we cut through the ceiling drywall and insulation from inside.

Dust and debris happen. We contain it as best we can, but expect drywall dust in that room.

3. Flashing Installation

This is critical. Poor flashing means leaks within a year.

Quality skylights (Velux, for example) come with complete flashing kits designed for specific roof pitches and shingle types. We install them exactly per manufacturer specs.

Cheap skylights come with generic flashing. That's where problems start.

4. Interior Finishing

The skylight manufacturer provides the exterior unit and flashing. They don't provide interior framing or drywall.

You need someone to:

• Frame the interior light shaft (if you're going through an attic)
• Insulate the shaft
• Drywall and finish the shaft
• Paint it

We don't do interior finish work. You'll need a carpenter or handyman. Budget $400-800 for finishing a typical skylight shaft.

5. Code Compliance

Virginia building code requires:

• Tempered or laminated glass (safety glass)
• Proper flashing per manufacturer specs
• Adequate ventilation if it's a venting skylight
• Fire-rated assembly in certain applications

Permits are required in Henrico and Chesterfield. Inspection happens after installation.

Where Skylights Work Best (and Worst)

Best Locations

Master bathrooms. Natural light, ventilation (if it opens), privacy (ceiling height means no neighbors looking in).

Hallways and stairwells. Dark areas that don't have exterior walls for windows. Skylights transform them.

Kitchen islands. If your kitchen runs down the center of your house, a skylight over the island adds light where you work.

Home offices. Natural light reduces eye strain. Venting skylights provide fresh air without opening windows.

Problematic Locations

Over beds. Heat gain in summer, cold in winter, bright early morning sun. Most people regret bedroom skylights unless they're far from the bed.

South-facing on steep pitches. Too much direct sun in summer. Your AC will hate you. If you must go south-facing, budget for cellular shades ($200-400 per skylight).

Low-slope roofs (under 3:12 pitch). Skylights on flat or nearly flat roofs are more prone to leaks. Not impossible, but higher risk.

Directly under ridge vents. Limits where we can place ridge venting, which affects attic ventilation. Sometimes we can work around it. Sometimes it's a bad trade-off.

The Leak Question

"Don't skylights always leak?"

No. But poorly installed ones do.

We've replaced dozens of leaking skylights in Richmond. Common issues:

Wrong flashing for the roof pitch. Flashing designed for a 6:12 pitch doesn't work on a 4:12 pitch. Water runs differently.

Caulk instead of proper flashing. Some installers skip the manufacturer's flashing kit and try to seal everything with caulk. Fails within 2-3 years.

No ice and water shield. In leak-prone areas (which skylights definitely are), ice and water shield under the flashing is essential. Not all installers use it.

Skylight installed in a valley. Water volume overwhelms the flashing. We refuse to do this.

When installed correctly with quality materials, skylights don't leak. We've installed over 60 in the past 5 years. Zero callback for leaks.

Brands That Actually Work

Velux: Industry standard. Excellent flashing kits, good warranties, readily available parts. Most expensive, but worth it. Our default recommendation.

Sun-Tek: Good mid-range option. Solid construction, decent flashing. About 20-30% cheaper than Velux.

Fakro: European brand, similar quality to Velux, sometimes slightly cheaper.

Tubular skylights: Solatube is the premium brand. Velux Sun Tunnel is good too. The off-brands are hit or miss.

What we don't install: No-name brands from big-box stores. The $200 skylight special. The flashing kits are garbage, and we're not putting our name on a leak waiting to happen.

Tubular vs. Traditional Skylights

Tubular skylights (Sun Tunnels):

Pros:

• Easier to install (smaller roof penetration, less framing)
• Work through attics (no light shaft needed if attic is shallow)
• Less heat gain/loss
• Cheaper ($600-900 installed)
• Don't require cutting rafters/trusses in most cases

Cons:

• Less light than a full skylight
• Can't open for ventilation
• Limited to smaller rooms (bathrooms, closets, hallways)
• Look like recessed lights from inside (less dramatic)

Traditional skylights:

Pros:

• Much more light
• Can open for ventilation (venting models)
• Architectural feature (adds value)
• Some include rain sensors, remote controls, solar power

Cons:

• More expensive ($1,000-2,000+ installed)
• Require more structural work
• More heat gain in summer, more heat loss in winter
• Need interior finishing (light shaft drywall, paint)

For bathrooms and closets, tubular often makes more sense. For living spaces where you want real impact, traditional skylights win.

Richmond-Specific Considerations

Summer heat. Skylights add heat gain. If you're adding one to a south-facing roof, expect your cooling costs to go up $50-100 per year unless you add cellular shades.

Storm resistance. Tempered glass skylights handle hail well. We saw several Richmond homes with skylight damage after the August 2024 derecho, but all were older units with acrylic domes (not glass).

HOA approval. If you're in Wyndham, Brandermill, or similar communities, skylights usually need architectural committee approval. Submit before installation. We've seen one homeowner in Short Pump forced to remove a skylight because they didn't get HOA approval first.

Permit inspections. Henrico typically inspects within 2-3 days of calling. Chesterfield can take 5-7 days. Factor that into your roof replacement timeline.

What to Ask Before Adding a Skylight

"Will I need to cut rafters or trusses?" Affects cost and structural requirements.

"What brand do you recommend and why?" Should be Velux or similar quality. If they recommend a brand you've never heard of, ask why.

"How will you flash it?" Should be manufacturer's flashing kit plus ice and water shield.

"Who handles the interior finish work?" Clarify whether that's included or separate.

"What's the warranty?" Velux offers 10-20 years depending on the model. We warranty our installation for the life of the roof.

"Can you show me photos of your skylight installations?" They should have plenty. Look for clean flashing, proper integration with shingles, finished projects (interior and exterior).

Our Process

When adding skylights during a roof replacement:

1. We discuss placement during the estimate phase
2. Check attic framing to confirm feasibility
3. Order skylight with appropriate flashing kit for your roof pitch
4. Frame the opening during tear-off phase
5. Install skylight with full perimeter ice and water shield
6. Flash per manufacturer specs (we follow the instructions exactly)
7. Shingle around it properly
8. Cut interior opening and provide rough framing
9. Connect you with finish carpenter if you don't have one

You get photos of each step (especially the flashing before shingles go on).

Final Thoughts

Skylights transform dark spaces. When done right, they're one of the best upgrades you can make during a roof replacement.

But they're not cheap. And they're not as simple as cutting a hole and dropping in a window.

Budget appropriately. Use quality products. Hire someone who's installed dozens, not attempting their first one on your roof.

And if you're on the fence? A tubular skylight in a small bathroom or hallway runs $700-900 and gives you a low-risk way to see if you like the effect before committing to larger, more expensive units elsewhere.
