1. Check Your Home's Requirements
Roof Structure Requirements
Before installing a skylight, it's essential to assess your roof's structural strength. Most residential roofs are built to handle around 20 lbs/ft² of weight. Adding a skylight introduces extra weight from the skylight itself and potential live loads like snow or wind. Skylights are typically designed for roofs with rafters spaced 16–24 inches apart, and the slope of your roof is a critical factor in picking the right model.
Light and Air Flow Needs
The size and style of your skylight should match your room's specific needs. A general rule of thumb is to keep the skylight's size between 5–10% of the room's floor area. This balance ensures adequate lighting without compromising energy efficiency. Here's a quick guide to choosing the best placement based on light quality:
| Location | Light Quality | Best For |
|---|---|---|
| North-facing | Consistent, soft light | Home offices, art studios |
| South-facing | Maximum sunlight | Living spaces, dark hallways |
| East-facing | Morning light | Bedrooms, breakfast nooks |
| West-facing | Afternoon light | Living rooms, dining areas |
Modern skylights can also improve ventilation, which is especially helpful in moisture-prone areas like bathrooms and kitchens. These models not only enhance airflow but can also reduce the need for mechanical ventilation, contributing to better indoor air quality.
Local Weather Impact
Your local weather conditions are another key factor in skylight performance. For example, Colorado's unique climate, with over 300 sunny days each year, demands careful consideration when selecting a skylight. Proper glazing is especially important to handle the state's diverse weather patterns:
- Winter Protection
Heavy snowfall can lead to ice dams around skylights. Regular snow removal and choosing insulated skylights can help prevent leaks and damage. - Summer Performance
The intense summer sun in Colorado makes specialized glazing and low-E coatings essential. These features help maintain indoor comfort and keep energy costs in check. - Directional Placement
North-facing skylights offer steady, indirect light throughout the day, while south-facing ones maximize solar warmth during colder months.
2. Types of Skylights
Non-Opening Skylights
Fixed skylights are a simple and budget-friendly way to bring natural light into your home. These permanently sealed units work best in spaces where ventilation isn’t necessary, such as hallways or attics. With material costs ranging from $200 to $1,200, they’re a practical choice for brightening dark areas while keeping energy usage in check.
One major benefit of fixed skylights is their excellent weatherproofing. Since they don’t have moving parts, they’re less likely to develop leaks and typically need less upkeep compared to vented options. For better energy efficiency, consider models with low-emissivity (low-e) glass, which helps regulate indoor temperatures all year round. If you’re looking for skylights that also improve airflow, vented skylights might be a better fit - more on those in the next section.
Opening Skylights
Vented skylights offer the dual benefit of natural light and improved air circulation, making them a great choice for spaces that need ventilation. These skylights cost between $400 and $2,000, and their ability to enhance airflow can even help lower air conditioning expenses. They come in three main operational styles:
| Operation Type | Best For | Key Benefits |
|---|---|---|
| Manual | Easily accessible areas | Affordable and simple to use |
| Electric | Hard-to-reach spots | Convenient remote-controlled operation |
| Solar-powered | Energy-conscious homes | No need for electrical wiring |
If your space presents installation challenges, you might want to explore sun tunnels as an alternative.
Sun Tunnels
Sun tunnels are an excellent option when traditional skylights aren’t feasible. These systems channel daylight into your home through a reflective tube, with rigid sun tunnels capable of delivering up to 98% of the captured light into a room.
Choosing the right size sun tunnel depends on your room’s dimensions:
- 10-inch diameter: Best for smaller areas (43–108 ft²), costs range from $150 to $350
- 14-inch diameter: Suitable for medium-sized spaces, priced between $400 and $550
- 18-inch diameter: Ideal for larger rooms, with costs from $600 to $750
For most installations, rigid sun tunnels are recommended as they provide better light transmission. Flexible tubes, while easier to install around obstacles, aren’t as efficient at channeling light. Don’t forget to account for labor costs, which typically range from $150 to $250 per tube.
3. Materials and Longevity
Glass vs. Plastic Options
When choosing between glass and plastic skylights, it’s all about balancing clarity, durability, and cost. Glass skylights are known for their long-lasting clarity, making them perfect for spaces where appearance matters. For added benefits, double-paned glass units filled with argon gas provide excellent temperature control and help reduce noise.
Plastic skylights, available in polycarbonate and acrylic, are more budget-friendly and highly durable. Polycarbonate, for example, is 250 times stronger than glass and 30 times stronger than acrylic, making it ideal for areas that face severe weather or potential impacts. While plastic options are less expensive upfront, there are some differences worth noting:
| Feature | Glass | Polycarbonate | Acrylic |
|---|---|---|---|
| Initial Cost | High | Lower | Lowest |
| Impact Resistance | Good | Excellent | Good |
| Clarity Over Time | Maintains | Slight clouding | Some clouding |
| Insulation | Excellent | Good | Fair |
| UV Protection | With coating | Built-in | Built-in |
Once you've decided on the skylight material, the next step is to consider the frame material for durability and energy efficiency.
Frame Materials
The frame of your skylight plays a significant role in its overall performance. Aluminum frames are widely used because they’re strong and resistant to weathering, but they can conduct heat, which may affect energy efficiency. For better insulation, vinyl frames are a great choice, offering excellent moisture resistance. Fiberglass and composite frames, on the other hand, provide superior insulation and stability, though they come with a higher price tag.
If you’re drawn to a classic look, wood frames provide natural insulation and a timeless aesthetic. However, they do require consistent upkeep to prevent wear and tear. For homes in coastal areas, selecting corrosion-resistant materials like fiberglass or composite is especially important. These options strike a good balance between durability and thermal performance, even if they require a bit more investment upfront.
Glass Treatments
Modern glass treatments can take your skylight to the next level by improving energy efficiency and reducing maintenance. Low-E coatings, for instance, reflect 50% to 90% of infrared light, helping to keep indoor temperatures steady and potentially cutting energy costs.
Here are some additional glass treatment options:
- Laminated glass: Blocks about 99% of harmful UV rays.
- Self-cleaning glass: Designed to break down dirt using sunlight and rain, making it ideal for hard-to-reach installations.
- Tinted glass: Helps minimize heat gain and glare, particularly useful in areas with constant sunlight.
Your local climate should guide your choice of glass treatments. Low-E coatings are versatile, working well in both hot and cold regions. In sunnier areas, tinted glass can be particularly effective. For the best energy performance, consider combining Low-E coatings with double-paned, argon-filled glass units.
4. Energy Savings and Location
Energy Ratings
When choosing an energy-efficient skylight, pay attention to NFRC ratings like the U-factor and SHGC. A lower U-factor indicates better insulation, while a lower SHGC reduces unwanted heat gain. Opt for skylights certified by ENERGY STAR that align with your region's guidelines. For example, in southern climates, ENERGY STAR typically recommends a U-factor of 0.40 or less and an SHGC of 0.25 or less, helping to cut cooling costs. With the right skylight, energy expenses could drop by as much as 40%. Once you've selected the skylight, consider its placement to maximize these energy-saving benefits.
Best Placement Spots
Where you place a skylight significantly impacts its energy performance:
- South-facing: Provides ample sunlight all day, making it ideal for spaces like living rooms, kitchens, or home offices.
- North-facing: Offers steady, indirect light with minimal heat gain, great for areas needing consistent illumination.
- East-facing: Perfect for bedrooms or breakfast nooks, as it captures soft morning light.
- West-facing: Brings in afternoon light but may require additional measures to manage heat.
To maintain efficiency, keep skylight size to about 5% of the room's floor area if the space already gets plenty of natural light. For darker rooms, you can increase skylight coverage up to 15%. If heat gain becomes an issue, explore light control options to better regulate indoor conditions.
Light Control Options
Light control features can fine-tune how much light and heat your skylight lets in:
| Control Type | Function | Best For |
|---|---|---|
| Exterior Shades | Reduce heat to a minimum | Hot climates |
| Interior Blinds | Adjust light levels easily | All climates |
If you already have a skylight, adding blinds or shades can improve its energy efficiency. Exterior shades, in particular, are more effective at reducing heat compared to interior options. This makes them especially useful in warmer areas, where managing solar heat gain is key to keeping your home comfortable and lowering cooling bills.
