Skylight Installation & Maintenance Guide

How to Choose, Install, and Maintain Skylights for a Brighter, More Efficient Home:

Skylights are a great way to bring natural light into your home, improve ventilation, and enhance its overall design. However, proper installation and maintenance are essential to preventing leaks and maximizing energy efficiency.

QuillCraft Construction provides expert skylight installation and maintenance to ensure a secure fit and long-lasting performance. This guide covers everything from choosing the right skylight to proper installation techniques and long-term upkeep, so you can feel confident in the quality and durability of your investment.

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.
