Skylights bring natural light into your home, reduce dependence on artificial lighting, and can transform dark interior spaces into bright, inviting rooms. But installing a skylight in Florida is different from installing one in Oregon or Minnesota. The intense sunshine, extreme heat, hurricane risk, and heavy rainfall that define Pinellas County's climate all influence which skylights work best, how they should be installed, and what they will cost.
This guide covers everything Pinellas County homeowners need to know about skylight installation: the different types available, realistic cost expectations, Florida-specific requirements for hurricane resistance and energy efficiency, flashing best practices, and a head-to-head comparison of the two leading skylight brands.
Whether you are building a new home, replacing an aging skylight, or adding natural light to a bathroom, kitchen, or hallway, this guide will help you make an informed decision.
Skylight Types: Fixed, Vented, and Tubular
There are three main categories of skylights available for residential installation in Pinellas County. Each serves a different purpose and comes at a different price point.
Fixed Skylights
Fixed skylights are the simplest and most common type. They do not open and exist solely to let light into the home. Key characteristics include:
- Non-operable design with no moving parts, reducing maintenance requirements and potential failure points
- Available in a wide range of sizes, from small accent windows to large architectural features
- Can be flat, domed, or pyramid-shaped depending on the manufacturer and model
- Available with impact-rated glass for Florida hurricane zone compliance
- The most affordable option per square foot of glazing area
- Best for rooms where ventilation is not needed but natural light is desired
Vented (Operable) Skylights
Vented skylights can be opened to allow air circulation in addition to providing natural light. They come in two varieties:
- Manual vented: Opened and closed by hand using a crank handle or push rod. Less expensive but requires physical access to the skylight.
- Electric or solar-powered: Opened and closed via remote control, wall switch, or smart home integration. Many models include rain sensors that automatically close the skylight when moisture is detected, which is a particularly valuable feature for Florida's sudden afternoon thunderstorms.
Vented skylights are ideal for kitchens, bathrooms, and other areas where moisture buildup is a concern. The ability to release hot air that rises to the ceiling can also improve comfort in rooms with high ceilings. However, the mechanical components add cost and create additional points that may need maintenance over time.
Tubular Skylights (Sun Tunnels)
Tubular skylights (also called sun tunnels or light tubes) use a small dome on the roof connected to a reflective tube that channels sunlight down to a diffuser lens in the ceiling. They are distinct from traditional skylights in several ways:
- Much smaller roof penetration (typically 10 to 14 inches in diameter) compared to traditional skylights
- Can bring light to interior rooms that are not directly below the roof, routing through attic spaces
- Significantly lower cost than traditional skylights
- Minimal heat gain due to the small opening and reflective tube design
- Quick installation, often completed in 2 to 4 hours
- Some models include an integrated light kit for nighttime use
- Ideal for bathrooms, closets, hallways, and other small spaces
Cost Breakdown: $500 to $3,000+
Skylight installation costs in Pinellas County depend on the type of skylight, the size, whether impact-rated glass is required (it almost always is in Florida), and the complexity of the installation. Here is a detailed cost breakdown:
| Skylight Type | Unit Cost | Installation Labor | Total Installed |
|---|---|---|---|
| Tubular (10 to 14 inch) | $200 to $500 | $250 to $500 | $500 to $1,000 |
| Fixed (standard size) | $300 to $800 | $500 to $1,200 | $800 to $2,000 |
| Fixed impact-rated | $500 to $1,200 | $500 to $1,200 | $1,000 to $2,400 |
| Vented manual | $500 to $1,000 | $700 to $1,500 | $1,200 to $2,500 |
| Vented electric/solar | $800 to $1,500 | $700 to $1,500 | $1,500 to $3,000+ |
| Custom/large architectural | $1,500 to $4,000+ | $1,000 to $3,000+ | $2,500 to $7,000+ |
Additional Cost Factors
- Roof type: Installation on tile roofs costs more than on shingle roofs due to the additional work required to remove and replace tiles around the opening
- Light shaft construction: If the skylight is installed in a room with an attic above it, a light shaft (framed tunnel from the roof to the ceiling) must be built. This adds $300 to $1,500 to the project
- Drywall and painting: Interior finishing of the light shaft opening typically adds $200 to $500
- Electrical work: Vented electric skylights may require wiring, adding $150 to $400
- Permit fees: $150 to $300 in Pinellas County (see our permit guide)
- Blinds or shades: Interior or external skylight blinds add $150 to $600 per unit and are highly recommended in Florida to control heat gain
Florida-Specific Considerations
Installing a skylight in Pinellas County comes with unique challenges and considerations that do not apply in many other parts of the country. Understanding these factors is essential for making the right choices:
Intense Solar Heat Gain
Florida's intense sunshine means skylights can introduce significant amounts of heat into your home. A skylight that is wonderful in Seattle could turn a room into an oven in Clearwater. To manage heat gain in Pinellas County:
- Choose skylights with a low Solar Heat Gain Coefficient (SHGC), ideally 0.25 or lower
- Select low-E (low emissivity) glass that reflects infrared heat while allowing visible light through
- Consider north-facing roof slopes for skylight placement to minimize direct sun exposure
- Install skylight blinds or shades for additional heat control during peak sun hours
- Avoid east-facing and especially west-facing installations where afternoon heat gain is highest
Heavy Rainfall
Pinellas County receives approximately 50 inches of rain per year, much of it in intense tropical downpours. This makes waterproofing critical:
- Professional installation with proper flashing is non-negotiable
- Choose skylights with integrated flashing systems designed for your specific roof type
- Ensure proper saddle or cricket construction on the upslope side to divert water around the skylight
- Regular inspection of sealant and flashing is essential to prevent leaks over time
UV Degradation
The same UV radiation that damages roofing materials in Florida also affects skylight components. Plastic domes can yellow and become brittle over time. Sealants around the skylight frame degrade faster than in less sunny climates. Choosing high-quality skylight units with UV-resistant materials and budgeting for periodic sealant maintenance helps ensure long-term performance.
Hurricane Ratings and Impact Resistance
Hurricane protection is not optional for skylights in Pinellas County. The Florida Building Code requires all glazed openings in the Wind-Borne Debris Region (which includes all of Pinellas County) to resist impact from windborne debris or be protected by approved shutters or screens.
Impact-Rated Skylights
Impact-rated skylights are built with laminated glass (similar to automotive windshield glass) or polycarbonate glazing that can withstand the impact of a large missile test (a 2x4 piece of lumber fired at the glass at 50 feet per second). When struck, the glass may crack but stays in the frame, preventing water and wind intrusion.
Benefits of impact-rated skylights in Pinellas County:
- No need for separate shutters or covers during hurricane preparation
- Continuous protection even if you are away from home when a storm approaches
- May qualify for insurance premium discounts on your wind mitigation report
- Better sound insulation compared to standard glass
- Enhanced security against break-ins (an additional benefit)
Alternative Protection Methods
If you install a non-impact-rated skylight, you must have an approved protection system in place:
- Permanently mounted hurricane screens that can be deployed over the skylight
- Removable polycarbonate panels rated for wind-borne debris
- Metal shutters designed specifically for skylight openings
While these alternatives can cost less upfront than impact-rated glass, they require manual installation before each storm and may not provide the same insurance benefits. For most Pinellas County homeowners, the convenience and reliability of impact-rated skylights makes them the better long-term investment.
Flashing and Waterproofing Requirements
Proper flashing is the single most important factor in preventing skylight leaks, and in Florida's heavy-rain climate, there is zero margin for error. Skylight flashing in Pinellas County must account for:
Step Flashing and Counter Flashing
Skylight installations require layered flashing systems that integrate with the surrounding roofing material:
- Step flashing on the sides, woven into each course of shingles or integrated under tile rows
- A saddle or cricket on the high side (upslope) to divert water around the skylight
- An apron or kick-out flashing on the low side to direct water onto the roof surface below
- Sill flashing and pan flashing at the base as secondary waterproofing
Manufacturer Flashing Kits
Both Velux and Fakro offer engineered flashing kits designed specifically for their skylight models and for different roof types (shingle, tile, metal). Using the manufacturer's flashing kit is strongly recommended because:
- They are engineered to work with the specific skylight frame dimensions
- They have been tested to meet Florida Building Code water penetration standards
- Using them typically maintains the manufacturer's warranty
- They include all necessary components, reducing the risk of missing a critical piece
Common Flashing Mistakes in Florida
The most common causes of skylight leaks in Pinellas County are:
- Relying on sealant (caulk) instead of proper mechanical flashing. Sealant is a supplement, not a substitute for flashing.
- Improper integration with tile roofing, which requires specific techniques different from shingle roofs
- Missing or undersized saddle/cricket on the upslope side, allowing water to dam up against the skylight frame
- Using flashing designed for a different roof type (for example, shingle flashing on a metal roof)
Energy Impact: Heat Gain vs. Lighting Savings
The energy impact of skylights in Florida is a balancing act between unwanted heat gain and valuable lighting savings. Understanding both sides helps you make a decision that works for your home and budget.
Heat Gain (The Downside)
In Pinellas County's climate, cooling costs are a major household expense. A poorly specified skylight can increase your cooling load by allowing solar heat directly into your living space. The key metrics to evaluate:
- Solar Heat Gain Coefficient (SHGC): This number ranges from 0 to 1, with lower numbers meaning less heat gain. For Florida, look for SHGC of 0.25 or lower.
- U-Factor: Measures how well the skylight insulates. Lower is better. For Florida, a U-Factor of 0.50 or lower is recommended.
- Visible Transmittance (VT): How much visible light passes through. Higher is better for natural lighting. A VT of 0.40 to 0.60 provides good light while controlling heat.
Lighting Savings (The Upside)
Skylights reduce your dependence on electric lighting during daylight hours, which in Florida means roughly 12 to 14 hours per day depending on the season. The savings include:
- Reduced electricity consumption from artificial lighting (10 to 30 percent of a room's lighting energy depending on the space)
- Less heat generated by light fixtures (incandescent and even LED lights produce some heat)
- Reduced need for task lighting in kitchens, offices, and work areas
- Potential eligibility for the federal energy efficiency tax credit (currently up to $600 for qualifying skylights with Energy Star certification)
Net Energy Impact in Pinellas County
For most Pinellas County homes, a properly specified skylight (low SHGC, low-E glass, appropriate size for the room) will result in a modest net increase in annual energy costs of $20 to $80 due to additional cooling load. However, this cost is often offset by the lighting savings and the quality-of-life benefits of natural light. Adding interior blinds and choosing north-facing placements can reduce or eliminate the net energy penalty entirely.
| Skylight Specification | Estimated Annual Heat Gain Cost | Estimated Annual Light Savings | Net Impact |
|---|---|---|---|
| Standard glass, south-facing | +$120 to $200 | -$40 to $80 | +$80 to $120 cost |
| Low-E glass, south-facing | +$60 to $100 | -$40 to $80 | +$0 to $40 cost |
| Low-E glass, north-facing | +$20 to $50 | -$30 to $60 | -$10 to $10 (neutral) |
| Tubular, any orientation | +$5 to $15 | -$20 to $40 | -$5 to $25 savings |

Installation Process and Permits
Skylight installation in Pinellas County requires a building permit because it involves creating a new roof penetration. Here is what the process looks like from start to finish:
Step-by-Step Installation Timeline
- Consultation and planning (1 to 2 weeks): A roofing contractor evaluates your roof structure, discusses placement options, and provides a detailed quote. Placement is critical in Florida to balance light and heat gain.
- Permit application (1 to 7 days): Your contractor submits the building permit application with product specifications, structural details, and installation plans.
- Material ordering (3 to 10 days): Impact-rated skylights are sometimes special-order items that may not be stocked locally. Plan for lead time.
- Roof opening and framing (day 1): The contractor cuts the roof opening, frames the curb, and installs structural support as needed.
- Skylight and flashing installation (day 1 to 2): The skylight unit is set in place, and the flashing system is integrated with the surrounding roofing material.
- Interior finishing (day 2 to 3): Light shaft construction (if needed), drywall, insulation, and painting.
- Inspection (scheduled after completion): The building inspector verifies the installation meets code requirements for structural integrity, waterproofing, and impact resistance.
Total project timeline from contract signing to completed installation typically runs 2 to 4 weeks in Pinellas County, with the actual on-site work taking 1 to 3 days depending on the complexity and whether a light shaft is needed.
