Skylights: Installation, Repair, and Leak Prevention

Let’s face it. Nothing feels quite like natural sunlight pouring into your home or business. Skylights bring that daylight indoors, making spaces feel bigger, brighter, and more welcoming. But with that beauty comes risk—leaks, drafts, and repairs that can dampen your day fast.

At Reston Roofing, we’ve seen it all. From flawless installations to urgent leak repairs in the middle of a stormy night, our emergency roofing team is your go-to for skylights that stand the test of time. Here’s how to get the most out of yours.

Choosing the Right Skylight

Picking a skylight isn’t just about the look. It’s about function, energy efficiency, and placement. The right skylight acts like a window to the sky—without becoming a hole in your roof.

Common Skylight Types

• Fixed skylights: Great for bringing in sunlight but don’t open for ventilation.
• Ventilated skylights: Open up to let in fresh air—ideal for kitchens, bathrooms, and attics.
• Tubular skylights: Small, discreet, and perfect for hallways or closets where roof space is tight.
• Custom shapes and sizes: Designed to fit unique rooflines or architectural needs.

Placement Matters Think of your roof as a canvas. The position of your skylight determines how much light and heat you get. Too much direct sun, and rooms can overheat. Too little, and you might not notice a difference. South-facing skylights offer the most light but may need blinds or glazing to control glare. North-facing ones provide cooler, consistent illumination.

Energy Efficiency Advice A well-placed skylight can cut energy bills and boost comfort. Look for:

• Double-glazed or triple-glazed panes for insulation
• Low-E coatings to reflect UV and infrared
• Solar-powered shades for easy control

Tip: The U.S. Department of Energy recommends ENERGY STAR® certified skylights for improved efficiency and comfort.

Professional Installation Process 🛠️

Installing a skylight is more like surgery than simple carpentry. Every cut matters. Every seal counts.

Steps We Follow

1. Roof Assessment: We inspect your roof structure, slope, and materials. Flat roofs and tile roofing require different techniques than shingle or metal roofing.
2. Sizing and Layout: We measure twice, cut once. Placement is mapped to avoid rafters and wires.
3. Framing the Opening: The roof and ceiling are carefully opened, with framing to support the new skylight.
4. Weatherproofing: We install flashing kits and sealants—these act like raincoats, channeling water away from the opening.
5. Mounting the Skylight: The unit is set in place and secured.
6. Insulation and Interior Finish: Gaps are filled, and interior trim is installed.
7. Leak Test: Before we leave, we simulate rain to check for leaks.

Why Call the Pros? DIY mistakes are easy to make. Even a small gap can lead to big leaks. Our team follows standards from the International Building Code (IBC) and OSHA safety guidelines to keep your home or business safe and dry.

Preventing and Repairing Leaks

A skylight leak isn’t just a drip. It’s a warning sign. Left unchecked, water can damage insulation, drywall, and the roof structure itself.

Common Leak Causes

• Faulty flashing: Flashing is the metal apron around the skylight. If it’s bent or cracked, water sneaks in.
• Aging sealants: Over time, caulk or sealants dry out and crumble.
• Condensation: Poor insulation or Ventilation & Insulation near you can cause moisture build-up.
• Improper installation: Gaps, misaligned frames, or skipped steps lead to big headaches.

Signs of Skylight Leaks

• Water stains on ceilings or walls
• Peeling paint or bubbling drywall
• Drips during rainstorms
• Unexplained drafts

Tip: Touch the drywall around your skylight after a rain. If it feels soft or damp, it’s time to act.

How We Fix Leaks

• Remove and replace damaged flashing
• Reseal joints with commercial-grade caulk
• Inspect and upgrade insulation around the skylight
• Repair or replace cracked glass or domes

In emergency roofing situations, we can install temporary covers or tarps until permanent repairs are made.

Maintenance Tips for Trouble-Free Skylights 🌞

Like any roof feature, skylights need regular checkups. Think of it like dental hygiene for your home—catching little issues before they become root canals.

Simple Maintenance Steps

• Inspect seals and flashing twice a year: Spring and fall are best.
• Clean the glass or dome: Use mild soap, water, and a soft cloth. Avoid harsh chemicals.
• Clear debris: Remove leaves, twigs, or snow from around the skylight.
• Check for condensation: Consider dehumidifiers or upgraded Ventilation & Insulation near you.
• Trim overhanging branches: Prevent falling limbs during storms.

Tip: Schedule a routine roof inspection with Reston Roofing during gutter cleaning or seasonal maintenance.

Energy Efficiency and Leak Warning Signs

A well-installed skylight should make your home feel brighter without hiking up your energy bills. Here’s what to watch for:

Frequently Asked Questions

How long does a skylight last?

Most modern skylights can last 15–20 years with proper care. Glass types, weather, and maintenance all play a role.

Can I install a skylight on a flat roof?

Yes—flat roof skylights are common, but require professional installation to ensure proper drainage and prevent leaks.

What’s the best way to prevent leaks?

Regular inspections, keeping seals and flashing in top shape, and choosing high-quality products make the biggest difference.

Will a skylight make my home hotter in summer?

Proper placement, glazing, and shades help control heat gain. Ask about Low-E coatings and vented designs.

Local and Seasonal Considerations 🌧️

In areas with heavy rain, snow, or hail, skylight choice and installation method matter more. Consider:

• Laminated or impact-resistant glass for storm-prone areas
• Extra flashing and waterproofing on low-slope or flat roofs
• Seasonal checks after storms or freeze-thaw cycles

For both homes and businesses, skylight maintenance is part of a healthy roof system—just like regular gutter cleaning, downspout repair, and preventative maintenance.
