If you answered yes, then installing Velux fixed skylights could be just the solution you’re after. Velux skylights are well-known for their durability and style, and they’re a brilliant way to enhance the ambience in any Australian home.
By the time you’re finished reading, you’ll have a thorough understanding of everything from planning and measuring your roof opening to sealing and finishing your new skylights. Ready to bask in loads of natural light without needing to switch on overhead lamps? Then let’s dive into this friendly, practical guide designed to help you install Velux fixed skylights with confidence.
Overview of Velux Fixed Skylights
Velux fixed skylights are a favourite among homeowners looking for a straightforward way to brighten up their surroundings. These skylights are installed in a fixed position, which means they do not open or close. While some skylights come with ventilation options, the fixed variants focus on letting light pour in while maintaining a seamless design.
With a Velux fixed skylight, you get superior clarity, a slim profile, and strong waterproofing elements. They’re engineered to cope with different weather conditions in Australia, from blistering sunshine in the summer to unexpected downpours during the wetter months. Plus, they’re known for their thermal efficiency, helping to regulate your home’s temperature by reducing heat transfer.
If you’re looking for a long-running, stress-free solution to add more light into your interior, you’ll find Velux fixed skylights tick all the boxes.
Preparing for Installation
Essential Tools and Materials
Before you start cutting into your roof, gather the following:
• Measuring tape
• Pencil or marker for outlining the skylight area
• Ladder or safe roof access system
• Circular saw or jigsaw (for cutting through roofing material and sheathing)
• Screwdriver or drill (for securing the skylight frame)
• Roofing nails or screws, as required
• Waterproof flashing kit specific to Velux skylights
• Insulation materials (such as foam or fibreglass)
• Silicone or roofing-approved sealant
Having these supplies on hand will make the project run far more smoothly. Nobody wants to climb up and down the ladder multiple times because a key tool was forgotten!
Safety Considerations and Roof Access Requirements
Safety should be your top priority. Confirm that you have a sturdy ladder and, if necessary, a harness system or scaffolding for extra security. Australian building codes may require you to have appropriate edge protection if your roof is over a certain height.
Plan your installation for a day with favourable weather conditions. Rain or strong winds can turn a simple roof job into a risky venture. Additionally, working under direct midday sun can be scorching in many parts of Australia, so consider the time of day to avoid extreme heat.
If your roof has a steep pitch, take extra precautions or enlist a helper. Also consider the structural integrity of the roof older homes might need reinforcement. If you have any doubts, get advice from a qualified roofing contractor before you proceed.
Common Installation Mistakes to Avoid
One frequent error is rushing the measuring stage. Precision is everything here; a skylight that doesn’t fit properly can lead to leaks and wasted energy. Double-check all measurements and mark your cutting lines clearly.
Another mistake is skimping on flashing and waterproof materials. This is one area where cheaper alternatives can come back to haunt you. Velux provides specific flashing kits designed for their skylights, so it’s best to use those instead of generic options.
Finally, some DIYers forget about proper insulation around the skylight. Without it, you can experience thermal bridging, condensation, or drafts. Keep in mind that insulation helps maintain a comfortable indoor environment, so don’t skip it. Next, we’ll walk through the step-by-step process of installing the skylight itself.
Step-by-Step Installation Guide
Planning and Measuring for the Perfect Fit
Start by choosing the optimal location for your Velux fixed skylight. Identify a spot between the roof rafters or trusses where you can fit the skylight’s frame without compromising structural supports. Use a measuring tape and pencil to outline the desired opening from inside the roof space. Make sure you account for any internal ceiling features or objects that might obstruct the skylight’s path.
Once you’ve confirmed your interior measurements, head outside to the roof. Double-check that your planned skylight location aligns with roof rafters and doesn’t clash with existing vents or chimneys. Mark the outer boundary of the skylight with chalk or a pencil. Ensuring accuracy now will save you from headaches later.
If you’re installing multiple skylights, take extra care that each one aligns properly with the others. Symmetry can make a big difference aesthetically, and it can also simplify the cutting and framing process.
Cutting the Roof Opening Safely
With your outlines drawn, it’s time for the opening. Use a circular saw or jigsaw to cut through the roof decking, following your marks precisely. Work slowly to avoid jagged edges or going off-track. Keep in mind that the roof is generally layered: shingles or metal sheeting on top, followed by underlayment and decking below.
Once you’ve cut out the roof decking, remove any nails or screws that might be lingering near the edges. Carefully check for electrical wires or plumbing lines—though these are more common in attic spaces, it’s still wise to be cautious in case of unusual home layouts.
Installing the Skylight Frame and Flashing
Place the skylight unit into the roof opening from the outside. If your skylight came with a mounting bracket or wooden frame, secure it firmly using screws or nails as recommended by the Velux installation guide. Ensure it sits flush and is level in all directions. A slightly tilted skylight can lead to uneven water run-off, increasing the risk of leaks.
Next, attach the flashing around the skylight’s perimeter. Velux flashing kits are designed to integrate with different roof types tile, metal, or shingle. Follow the manufacturer’s instructions and anchor the flashing as directed. The main goal is to create a watertight seal that routes rainwater away from the skylight, preventing it from seeping into your roofing layers.
Ensuring Proper Insulation and Waterproofing
Now’s the time to insulate around the skylight frame. Insert foam or fibreglass insulation into the gap between the skylight framing and the roof structure. This seals off drafts and reduces heat exchange. Where possible, use moisture-resistant insulation to cut down on the chance of condensation inside the cavity.
After insulating, apply high-quality roofing sealant or silicone along the joints, focusing on any potential weak spots. Double-check areas where the skylight flange meets the roof surface. A thorough seal helps guarantee no water can slip through during a downpour.
It’s also useful to add an underlayment or specialised membrane around the skylight’s perimeter before finalising the roof covering. This is particularly important in regions with heavy rain or strong winds, common across many parts of Australia.
Final Checks and Sealing
Before you declare the job done, inspect everything carefully. From the roof exterior, ensure there are no lifted corners on the flashing and that all nails or screws are properly seated. From inside, confirm the skylight is level and there are no visible gaps around the edges.
Perform a quick water test using a hose on a gentle setting. Spray around the skylight to see if any moisture makes its way in. If you spot any dampness along the edges, address it immediately with extra sealant. It’s far easier to fix leaks now than to discover them during a heavy storm.
Once you’re confident everything is sealed and secure, pat yourself on the back you’ve successfully installed a Velux fixed skylight. Next, let’s answer some common questions that people tend to ask when entering the world of skylights.
