Velux Skylight Replacement & Roof Window Upgrades in Sydney

Sydney Roofers is an experienced Velux replacement specialist, offering like-for-like swaps or full upgrades to modern, high-performance Velux skylight models. If your existing Velux or Fakro roof window is leaking, fogging up, or no longer operating correctly, we can install a new generation skylight with advanced features such as laminated safety glass, thermal insulation layers, solar-powered ventilation, and rain sensors.

All replacements are performed to Velux Australia’s specification guidelines, ensuring the new unit is properly flashed, sealed, and warranted. We also retrofit older-style manual units with new motorised systems, integrating remote control and smartphone automation for improved usability and energy control. Whether your unit is on a pitched roof, flat roof, or located in a high or inaccessible space, we’ll upgrade it for better performance, safety, and aesthetics.

Replacing Cracked Domes, Fogged Panels & Discoloured Skylight Covers

Over time, acrylic skylight domes can become brittle, yellowed, or develop hairline cracks from UV exposure and thermal expansion. We remove aged or damaged domes and replace them with high-impact acrylic or double-glazed units designed to resist cracking, block UV radiation, and reduce thermal gain. This not only improves internal light quality but also enhances the insulation value of the skylight and the comfort of your home.

Custom Skylight Retrofits with Energy-Efficient Glazing

Many homes across Sydney were built with outdated skylights that offer poor insulation and minimal UV protection. We offer complete retrofit services to upgrade older units with modern, high-performance skylight systems that feature low-e coatings, argon-filled double glazing, and thermally broken frames. These replacements significantly reduce heat transfer, control glare, and contribute to lower energy consumption year-round. Custom retrofits are available for pitched, flat, and vaulted ceilings, ensuring the new skylight integrates perfectly with your interior space.

Skylight Flashing Upgrades During Replacement

Replacing a skylight is the ideal time to upgrade or correct the surrounding flashing. We fabricate and install new apron flashings, step flashings, and saddle flashings as needed to ensure water is directed away from the skylight opening and toward the roof’s drainage paths. Flashings are made from premium Colorbond® or Zincalume® steel, and sealed using UV-stable, NCC-compliant waterproof membranes. Proper flashing is critical for leak prevention and for maintaining the integrity of the roof around your new skylight.

Roof Structure Adjustments and Internal Lining Finishes

If the existing skylight opening is misaligned, undersized, or showing signs of rot, we carry out structural roof framing adjustments before installing the new unit. This includes reframing rafters, adding noggins or curb supports, and correcting fall levels for membrane compatibility on flat roofs. Inside the home, we provide clean internal finishes around the skylight shaft, whether in plasterboard, timber reveals, or recessed bulkhead designs, ensuring the interior looks as good as the new installation performs.

A skylight replacement isn’t just a fix — it’s an opportunity to enhance the comfort, efficiency, and beauty of your home. At Sydney Roofers, we provide high-quality skylight upgrades that solve leaks, modernise your roofline, and comply with the latest energy and safety standards. With decades of experience, precision installation methods, and Sydney-wide service coverage, we are the trusted name for professional skylight replacement. Book a site inspection today and let us transform your home with a new, high-performance skylight solution tailored to your needs.

Full-Service Skylight Replacement for Homes, Extensions & Renovations

Our skylight replacement services are tailored to suit the roof type, ceiling structure, and design preferences of each Sydney property. We begin by removing the old skylight unit, assessing the condition of the surrounding roof area, and preparing the new opening or curb mount as required. The replacement skylight is then fitted using brand-specific or custom-fabricated flashing kits, ensuring a seamless, leak-free integration into your existing roofing system.

Whether you’re upgrading during a major home renovation or replacing a failed skylight due to leaks or age, we provide advanced double-glazed skylight systems that improve energy efficiency, reduce UV exposure, and restore natural lighting to your space. For properties in bushfire-prone areas, we install BAL-rated skylights with fire-compliant glazing and flashings in accordance with AS 3959. Our goal is not only to fix the leak — but to improve the entire performance and longevity of the roof-lighting system.
