Skylights are an excellent way to bring natural light into your home, adding warmth, brightness, and a sense of spaciousness to any room. However, to fully enjoy the benefits of a skylight, it’s important to ensure that it is installed correctly. Poor installation can lead to problems such as leaks, drafts, and reduced energy efficiency. In this guide, we provide expert advice and practical tips on skylight installation to help you make the most of your daylighting solution.

1. Choosing the Right Location for Your Skylight

One of the most critical factors in skylight installation is selecting the right location. The position of your skylight will determine how much light it brings in, how it affects the temperature of the room, and whether it may cause glare.

  • Consider Sun Exposure: Skylights facing south tend to bring in the most sunlight, which can be a benefit in cooler months but may cause overheating in summer. North-facing skylights provide softer, more consistent light. For east- or west-facing rooms, skylights will bring in morning or afternoon sun, respectively.
  • Avoid placing it near obstructions such as trees, chimneys, or ridges that may cast shadows, reducing the amount of natural light. Also, keep it away from water channels or valleys in the roof, which may compromise its waterproofing. By choosing an area with maximum exposure to daylight, you can optimise both the functionality and energy efficiency of your skylight.
  • Room Functionality: Think about the purpose of the room. In living rooms and kitchens, ample daylight can be a positive feature, but in bedrooms, you may want to avoid too much direct sunlight.
  • Avoiding Glare: Install the skylight at an angle to prevent glare. Roof slope and room orientation can affect light distribution.

By considering sun exposure, room use, and potential glare, you can select the ideal skylight location to balance natural light with comfort.

2. Selecting the Right Type of Skylight

There are several types of skylights available, each with its own benefits. Choosing the right type for your needs will ensure you get the most out of your skylight installation.

  • Fixed Skylights: Ideal for rooms where ventilation is not needed, such as living rooms and hallways. They provide maximum daylight without the need for additional features.
  • Ventilated Skylights: These are perfect for kitchens, bathrooms, and other areas where moisture or heat may build up. They allow fresh air to circulate, improving ventilation while bringing in natural light.
  • Tubular Skylights: If you have a small or confined space like a hallway or closet, tubular skylights (such as Solatube’s Daylighting Systems) are a great option. They are easy to install and provide a focused beam of natural light.

For rooms with higher ceilings, consider larger diameter tubes. Measure the distance between the roof and the ceiling to determine the correct number of extension tubes needed. If you encounter obstructions in your roof space, such as gas pipes, water pipes, or air ducts, use adjustable angle sections (0-90 degrees) to re-route the tubing for the best results.

Choosing the right skylight type based on your room’s needs will enhance both functionality and aesthetics.

3. Installing Skylights for Maximum Energy Efficiency

Skylights can significantly affect your home’s energy efficiency. Proper installation can help prevent heat loss in the winter and reduce heat gain in the summer.

  • Use Low-E Glass: Skylights with Low-E (low emissivity) coatings help regulate temperature by reflecting heat and UV rays, keeping your home cooler in summer and warmer in winter.
  • Double Glazing: Opt for skylights with double glazing to provide insulation and improve energy efficiency, reducing the need for heating and cooling.
  • Proper Sealing: Ensure your skylight is well-sealed to prevent drafts and water leaks. High-quality flashing kits, specifically designed for skylights, are crucial for preventing leaks and protecting your roof.
  • Ensure that all joints in your extension tubes overlap by at least 50mm and are sealed with aluminium tape to prevent air leaks. For angled or longer tubing, self-tapping screws can be used to reinforce the connection

By selecting energy-efficient materials and ensuring proper sealing, you can reduce your energy bills while enjoying natural light year-round.

4. Hire Professional Installers

While DIY installation can be tempting for those handy around the house to save the skylight cost, professional installation is always recommended to ensure safety and long-term performance.

  • Avoid Common Installation Mistakes: Professional installers can help avoid common pitfalls like improper sealing, incorrect placement, and structural damage to your roof.
  • Warranty Protection: Many skylight manufacturers, including Solatube, offer warranties that may only remain valid with professional installation.
  • Expertise in Roof Types: Different roofing materials require specific installation techniques. Professional installers will ensure that your skylight is securely and correctly fitted, regardless of your roof type.

Hiring experienced installers ensures that all safety measures are taken, from securing the tubing with wires or retainers for added support to verifying that your roof’s waterproofing properties remain intact throughout the process. A professional installation ensures peace of mind, ensure adhering to any environmental legal requirements for your area, such as Bush Fire legislation, and knowing your skylight will function optimally for years to come. When you buy Solatube skylights, you can rest assured we have certified installers across Australia who are well trained to provide professional installation. Call us on 131619 or find a dealer near you here.

If you are going to do DIY skylight installation, we suggest you allow at least 4 hours for the installation, particularly if this is your first skylight installation. Ensure you read all installation instructions including those for any accessories before starting installation to ensure the correct sequence of installation is followed.

5. Maintenance Tips for Skylight Longevity

Once your skylight is installed, regular maintenance is essential to keep it in top condition and ensure its longevity.

  • Cleaning: Dirt, dust, and debris can accumulate on the skylight, reducing the amount of light it allows in. Regular cleaning will keep your skylight clear and bright. Always use non-abrasive cleaners to avoid scratching the glass.
  • Inspect for Leaks: Check the skylight and surrounding roof area periodically for leaks, especially after heavy rain. Inspect the seals and flashing for any signs of wear and tear.
  • Check for Condensation: Excessive condensation inside the skylight can lead to water damage or mould. Ensure proper ventilation in the room and inspect the skylight for any signs of condensation buildup.
  • Always ensure that all adhesives, seals, and tapes are applied to dry surfaces, and remove protective film before prolonged exposure to the sun to avoid bonding issues

With these simple maintenance steps, you can enjoy the benefits of your skylight for many years.

6. Considering Alternatives to Traditional Skylights

While traditional skylights are a popular choice, there are modern alternatives that offer additional benefits. Solatube’s Tubular Skylights are an excellent option for homes that require focused light in small spaces. These systems are easy to install, offer superior light diffusion, and are highly energy-efficient.

For those concerned about temperature control, Solatube’s Solar Star Roof Ventilation can be installed alongside skylights to enhance airflow and reduce heat buildup in your attic, further improving energy efficiency.

  1. Hi Solatube Team,

    Could you please give me some advice? I tried to clean my skylight’s ceiling fixture (TierDrop) because some mosquitos stuck inside. I tried to turn it but didn’t move and I don’t want to destroy it. What is the best procedure to remove the plastic cover? Thanks, Peter

    Reply

    1. Hi Peter
      Remove the diffuser or decorative fixture by carefully twisting counterclockwise to separate it from the ceiling ring. To clean, wipe the diffuser or decorative fixture with a tissue or soft cloth. To reattach the diffuser or decorative fixture, simply align the tabs on the diffuser or decorative fixture to the ones on the ceiling ring and twist clockwise to secure.

  3. hello solatube.couple of questions for you please.i have an existing 410mm hole to fill in with a solatube .will one of yours cover it?.secondly do your diffusers throw the light differently e.g. optiveiw vs vision and what are differences between each if any.thankyou

    Reply

    1. Hi Jason,

      The larger model in our highest performing Brighten-Up series, the 290DS, requires a ceiling cut-out 375mm in diameter. In our mid-range Heavenly Intelligent series, the larger model HI400 requires a 415mm dia cut-out.

      When upgrading to a 290DS, patching-up that part of the ceiling with new plaster is ideal, however when this is not possible, Solatube installers often use a white dress ring to conceal the gap.

      As far as the different diffusers are concerned, the ones you mention are only applicable to the Brighten Up series, and yes, they do have slightly different characteristics, although much of the choice is purely aesthetic. Some diffusers fill the room with light better (OptiView, TierDrop) and some are better at softening light and reducing glare (TierDrop, JustFrost). JustFrost and Vusion are great all-round diffusers that look neat on the ceiling. The Brighten-Up series also has a number of effect lenses (these are standard inclusions, and sit above the diffuser in the tube) that can further enhance how natural light enters the interior.

  4. Have two solatube 290DS installed on concrete tile roof, some 21Deg pitch. These in 4/12 and 1/14 (Sydney). The older one start to drip due to tree leave accumulated, I cleaned by lifting tiles around and ok for a while. I notice the flashing ending under the edge tiles do not have an edge protection bent so water penetrates easy. I have being using some foam filler around to stop leaves accumulating. Is there a different solution to this problem?. Other than that yhey are great for the job they do. Thanks

    1. Hi Ric

      The Solatube tile flashings have ridges to allow water to run away and prevent water from going across the flashing edge. As these ridges are under the next laid tile, water should not be entering this area in a standard application. When in areas of heavy leaf build up regular cleaning is required to prevent a dam effect where water is not being allowed to flow naturally.

      If a representative of Solatube home is needed to attend site and meet with you they are happy to do this, and can be contacted on 9725 5433.

  5. we have one of your solar tubes with light and fan – at least 10 years old . The inner tube measures approx 240 while the outer measure of the whole decorative fitting is approx 400. The vent fan has failed – would this be a generic replacement fan motor that my electrician can replace or is it OEM.
    Will need part number if oem.
    PS very impressed we got over 10 years without a problem.

  6. to what length is the solatube brighten up series sun tunnel effective in providing adequate light? We are considering using a straight line tunnel from the roof, via a wardrobe on the 1st floor to the ground floor on a double storey home?

    Reply

    1. Hi Pourya,

      Solatube dealerships routinely install Brighten-Up to lower floors in multi-storey homes. Spectralight® Infinity tubing in the Brighten-Up series is unique for this type of application. All other tubular skylights on the market will general max out at about 2 meters, and most lower grade tubes typically at less than 1 meter.

      There are some variables to this, we can provide you with further technical information, but we rate the smaller 160DS model to still be very effective over 6 meter lengths, and the larger 290DS over 9 meter lengths. These lengths are based on the ability for the tubes to transfer at least 80% of captured light through to the ceiling location inside the home.

  7. I have a solartube 290 DS skylight, I want to change the globe, I’ve taken off the outer cover by turning it anti clockwise, but there is another cover that has to be removed so I can change the globe, I unscrewed the 4 screws which hang in there, but I can’t seen to remove that inner cover, I don’t want to force it, can you tell me how to do it.

  8. Hi guys,
    We had Solatubes installed 2 years ago and we have dead mozzies in the fitting.
    I’m aware of how to remove the diffuser, but there is a secondary clear section and need to access that to clean them out. How do I do it, the unit is secured with screws.

    1. Hi John

      We have suggested to other customers, to blow air through the small gap or piece of paper to dislodge. If this doesn’t work best to speak with the local Premier Dealer who installed to see what alternatives you have.

    1. Hi Craig, if less sunlight lands on the roof dome, less will be transfer to the interior of the home. Our general advice is to locate the dome on the roof where it will get as much sun as possible. In the Australia in the southern hemisphere, this is typically on the north side of the roof and away from shadow, be it from neighbouring buildings, the home’s own roof structure or vegetation. Unlike less advanced tubular daylighting systems, Solatube offers a greater amount of flexibility for roof dome locations in relation to where the light output is positioned on the ceiling inside the home. Solatube can transfer light over much greater distances without losing that light along the way, so the roof dome can be located quite a distance away to reach that sunny spot on the roof. We also have customers that prioritise the location of the roof dome to suit specific applications, for example they may choose to collect more of the eastern sun in the morning to illuminate an area above the breakfast bar in the kitchen.

  10. I understand more light will be transmitted from a sunny location. I also understand Solartube can transfer the light from greater distances. I have two in my winter home. However, are you saying, don’t waste you time and money in placing a Solartube in a shady location? In my particular situation, a shady location is the only option.

    Reply

    1. Hi Craig,

      We are confident that a Solatube daylighting system will harvest more light under the same circumstances than other similar products available on the market. Whether this is still worth pursuing is a value judgement. Our recommendation would be to start with your intended purpose for the skylight – how much light do you need/want in this space in the home. The answer may be different if you need natural light in a study/work space, then if it’s for a dark hallway that just needs a bit of extra light. Often you can compensate for a less than ideal roof location with a larger model, or by installing multiple units where one would have otherwise been perfectly adequate.

      Best idea would be to speak with the local Dealer to see what is possible for your home. If you type in your postcode in this link, will provide contact details to arrange a consult. https://solatube.com.au/solatube-premier-dealers/

  11. hi Solatube team, I am preparing to install a 160DS Solatube in our home office, that is on south side of home. We have sheet steel corrugated roof (19^ slope) & thus got the 250 corrugated flashing kit (beautifully made I will note). As far as lining up the roof penetration with the ceiling location (above my desk), can the centre of roof penetration be virtually exactly above the ceiling hole centre (so light tubing is dead plumb), or I see from side view drawing in install guide that the roof opening is slightly down-slope of the vertical plumb line. My goal is to place the Raybender dome as high on the roof as possible, as the roof flank being south side is facing due south, so want the dome as high as possible to acquire as much light available. Also the logic seems to have as little changes in light reflection as possible?

    1. Hi Michael,

      You can aim to have the roof dome directly above your preferred location for the diffuser on the ceiling. Usually some sort of offset from vertical is required – beams, battens, rafters in the roof, or to run the tube to the sunniest possible spot on the roof – hence there is a level of adjustment on the two angles provided in the kit (0-30 deg), although you also need to account for the roof pitch in that range. Using the standard angles, there will be no impact on the amount of daylight transmitted.

  12. Hi I have a tube light installed by another supplier.,Stupid .
    I have one of yours also. The new one has a square glass and flexishaft , the light is only half what your one gives. My question can I change the flexishaft for rigid tubing , obviously done by your good selves

    Hopeful
    B

    Reply

    1. Hi Brenda,
      Flexi shafts have very limited applications. Rigid tubes are much better, but even these can vary substantially between brands. In terms of changing the tubing in your skylight, this will depend on the diameters involved and how compatible they are with the rest of the skylight, namely the roof flashing, dome and the ceiling fixture. Have a chat with your local Solatube dealership, they’ll be able to give you the best advice on improving the performance of your skylight. https://solatube.com.au/solatube-premier-dealers/

  13. Hello there,
    we have a flat, metal roof and wonder if we can have a simple skytube inserted without it resulting in leaks when it rains. I imagine metal roofs can be problematic regarding a perfect seal? I hope not!

    Reply

    1. Hi Marilyn,

      Metal roof installations are very frequent and Solatube’s roof components have been successfully used around Australia and internationally for over 30 years – from cyclonic areas in the top end, to colder southern states, both in commercial and residential settings. You are correct to point out that flatter roofs require additional attention over higher pitched roofs, but Solatube dealerships and their trained installers will be able to recommend the correct components and installations technique to suit your specific property, the actual pitch and the metal roof profile. As a base guide, corrugated and Trimdek roofs will have the most options for a correct fit with tailored flashing kits, however Klip-lok and other deck type profiles can also be catered for using over-flashing and dry-panning techniques. Our recommendation is to always use a trained installer to secure the correct product and matching installation warranty for your skylight.

  16. Hello Solartube Team
    I have just removed the solartube diffuser Pt No 410320 for cleaning. An oil film is preventing me from cleaning thoroughly as the fixing rivets cannot be undone, there is no heads on them to get a firm hold on to turn them. The unit was installed 7 years ago. As we are repainting the ceilings we need to have the diffuser brought back to its new looking best. How much is a new diffuser if we cannot get it cleaned?

    Reply

  18. I want to put a sky light in but where I want it I is directly under my solar panel. How far away can the roof dome be offset so as to have the diffuser where I want it.

    1. Hi Dennis

      As far as you need to move it. We offer 90 deg bends and can take natural light further than any product available on the market. The length of tube will impact the cost by approximately $150 per Metre.
