A standard skylight size does not always fit an architect-designed roof, a heritage home, or an oddly shaped opening, and being told a project is too unusual is frustrating when you know a skylight would solve your lighting problem perfectly. You are in the right place. Ilanga Skylights and Roof Turbine Ventilators has designed and fitted custom skylights across Gauteng for over 20 years, built to the exact dimensions your roof needs.

What Custom Skylight Problems Do You Have?

Not every roof follows a standard shape. Heritage homes, architect-designed extensions, and older Gauteng properties often have roof pitches, dormers, or openings that a standard off-the-shelf skylight simply will not fit. Forcing a standard unit into an opening it was not designed for is one of the most common causes of leaks.

An existing skylight that has started leaking or cracking is another common problem. Rather than replace it with the same standard unit, this is often the right time to fit a custom size that solves the original design flaw for good.

DIY skylight kits are built to standard dimensions too, which means they run into the same problem on an unusual roof. Cutting a roof opening to fit a kit that was never designed for your exact roof shape is a common cause of costly leaks later.

Our Custom Skylight Services

We design and fit skylights to the exact dimensions and shape your roof needs, whether that means an unusual size, an angled opening, or a shape that does not match any standard product on the market. If your existing skylight has started leaking, cracking, or fogging up between the panes, our Skylight Repairs service assesses the unit and either reseals, replaces the glazing, or fits a full replacement, whichever solves the problem properly rather than just patching it.

For homeowners who want to handle part of the installation themselves, our DIY Skylight Kits service supplies a correctly sized kit with clear instructions, so you still get a unit built for your exact roof rather than a generic size that may not fit.

Every custom skylight uses materials that meet international quality standards, and comes with the same 15-year guarantee on workmanship and materials as our standard range.

Custom Skylights for Gauteng Homes and Businesses

Gauteng has a wide mix of roof styles, from heritage homes in older Johannesburg and Pretoria suburbs to modern architect-designed builds across Centurion and Midrand. A one-size-fits-all skylight rarely suits all of them, which is why we measure and design around your specific roof rather than starting from a catalogue size.

We work across Johannesburg, Pretoria, East Rand, West Rand, North Rand, South Rand, Centurion, and Midrand, on pitched, flat, tiled, and IBR roofs. Hailstorm season, from October to March, makes a proper custom fit even more important, since a badly sized or poorly sealed skylight is far more likely to fail in a bad storm than one designed for the exact opening.

Custom Skylights Across Gauteng’s Best Known Areas

Gauteng’s skyline tells its own story, and nowhere is that clearer than around Sandton and Nelson Mandela Square, where glass towers and architect-designed homes often call for a custom skylight rather than an off-the-shelf size. When a roofline is this deliberate, the skylight fitted into it needs to match, both in dimensions and in finish.

Head north towards the Union Buildings in Pretoria and the roofs tell a different story, heritage homes with pitched, tiled roofs built long before standard skylight sizes existed. These are exactly the properties where a custom-measured unit avoids the leaks that come from forcing a generic size into an opening it was never designed for.

Further out towards the Cradle of Humankind on the West Rand, older farmhouses and smallholdings often have roof structures that have settled and shifted over decades. A custom skylight design accounts for exactly this kind of real-world roof, rather than assuming every opening is perfectly square.
