Step 1: Choosing the Right Skylight
1. Types of Skylights
- Fixed Skylights: Non-opening, ideal for natural light without ventilation.
- Vented Skylights: Open manually or electronically for airflow, great for kitchens and bathrooms.
- Tubular Skylights: Small, reflective tubes that channel light into dark spaces, ideal for closets and hallways.
2. Skylight Glazing Options
- Tempered Glass: Strong and shatter-resistant.
- Laminated Glass: Offers better insulation and UV protection.
- Acrylic or Polycarbonate: Lightweight but prone to scratching.
3. Energy Efficiency Features
- Low-E Coatings: Reduce heat gain and UV damage.
- Double or Triple-Pane Glass: Improves insulation and prevents condensation.
Step 2: Skylight Placement & Roof Considerations
1. Best Locations for Skylights
- South-facing skylights capture the most sunlight but can overheat without tinting.
- North-facing skylights provide consistent, soft lighting.
- East-facing skylights offer morning sunlight.
- West-facing skylights provide evening light but can cause heat buildup.
2. Roof Slope & Framing Considerations
- Flat or low-slope roofs require curb-mounted skylights for waterproofing.
- Pitched roofs can use deck-mounted skylights, which sit flush with the roof.
- Check rafter spacing to determine the skylight’s width and size.
Step 3: Skylight Installation Process
1. Gather Tools & Materials
- Skylight unit
- Flashing kit (step flashing, saddle flashing, etc.)
- Roofing nails and screws
- Roofing sealant
- Utility knife
- Circular saw or reciprocating saw
- Tape measure and chalk line
2. Installing the Skylight
- Position and secure the skylight to the roof with screws.
- Install step flashing along the sides and saddle flashing at the top to prevent leaks.
- Seal around the skylight with roofing sealant to reinforce waterproofing.
- Reinstall shingles around the skylight to blend with the roof.
Step 4: Skylight Maintenance & Leak Prevention
1. Regular Inspections
- Check for cracks, condensation, or leaks around the skylight.
- Ensure flashing is intact and free of rust or lifting edges.
2. Cleaning the Skylight
- Use mild soap and water to clean glass surfaces.
- Remove debris, leaves, or dirt from the exterior to prevent water pooling.
3. Preventing Condensation & Overheating
- Use vented skylights or ceiling fans to control humidity.
- Install blinds or shades to reduce heat gain in summer.
