I Tried 5 Hacks Before Learning How to Cover Skylight Windows Properly

I remember the first July in my loft. I was so proud of that massive overhead window until the thermometer hit 90 and my living room felt like the inside of a convection oven. I sat on my sofa, squinting at the TV through a blinding glare, and realized I had no idea how to cover skylight windows without making my ceiling look like a construction site.

The problem with skylights is that they are architectural gems that quickly turn into thermal liabilities. You want the light, but you don't want the 3 PM solar gain that melts your candles and fades your rug. After a week of frantic googling and three failed DIY attempts, I learned the hard way that a window on a 45-degree angle requires a completely different logic than a standard vertical pane.

Quick Takeaways

• Temporary fixes like tape or tension rods will inevitably sag and fail due to heat and gravity.
• Exterior covers are the most effective for heat blocking but can be an eyesore and a safety risk to install.
• Cellular (honeycomb) shades are the interior design standard for insulation and light control.
• Motorization is a necessity, not a luxury, for any window higher than eight feet.

The 'What Can I Use to Cover My Skylight?' Panic

When the heat first hit, I went into a research spiral. I was searching for everything from 'skylight blind ideas' to a 'sun roof house cover'—which, let’s be honest, is what a skylight feels like when you’re sweating in your own kitchen. My initial fear was that any solution would look bulky or industrial. I needed shades for skylight glare, but I was terrified of drilling into my pristine white drywall and ending up with a mess of visible wires and heavy brackets.

The aesthetic pitfall here is treating a skylight like a regular window. You can’t just drape a piece of linen over it and hope for the best. Without a track or a tension system, gravity wins every single time. I spent hours looking at photos of beautiful rooms ruined by sagging fabric that looked more like a ghost haunting the ceiling than a design choice.

Phase One: Temporary Skylight Covers (And Why They Fail)

In a moment of pure desperation, I tried temporary skylight covers. I bought a roll of reflective 'blackout' film and some heavy-duty suction cups. It stayed up for exactly four hours before the heat softened the adhesive on the cups, and the whole thing drifted down onto my dining table like a sad, metallic kite. Then I tried tension rods with a lightweight voile, but the rods slipped because skylight shafts are rarely perfectly square.

These stopgaps are frustrating because they never quite block all the light. There’s always a sliver of blinding sun peaking through the side. If you are trying to sleep, that one laser beam of light is enough to ruin your morning. I eventually realized that if I wanted something that actually saved my bedroom from the 5 AM sun, I had to stop looking for a 'hack' and start looking for a system designed for gravity.

Stopping the Heat Outside: Exterior Skylight Covers DIY

There is a school of thought that says you should block the sun before it even hits the glass. This leads many people down the path of exterior skylight covers diy projects. People use bungee cords and shade cloth to create a 'hat' for their skylights. While this is incredibly effective at keeping the glass cool, it looks—to put it bluntly—terrible from the curb. It also means you have to climb onto your roof every time the seasons change.

If you are researching how to make skylight covers outside, please consider the wind. I once watched a neighbor's DIY mesh cover catch a gust and tear half the trim off his window frame. Unless you are buying a professional-grade exterior heat shield designed for your specific window model, you are better off managing the light from the inside where you can actually reach the hardware without a 20-foot ladder.

Upgrading the Inside: Actually Good Skylight Blind Ideas

The turning point for me was discovering cellular shades. Unlike a flat piece of fabric, cellular (or honeycomb) shades have a pleated structure that creates air pockets. This traps the heat in the 'cells' before it can radiate into the room. For a skylight, you want a side-track system. This is a thin rail that mounts inside the window shaft, holding the fabric taut so it can't sag in the middle.

I opted for motorized skylight cellular shades because my ceiling is twelve feet high. Trying to use a manual pole to crank a shade open every morning is a workout I didn't sign up for. With a motorized version, the fabric stays perfectly aligned in the tracks, and you can program them to close automatically during the hottest part of the day. It’s the only way to get that 'built-in' look that feels like part of the architecture rather than an afterthought.

My Final Advice on How to Cover Skylight Windows Permanently

If you're ready to stop covering up skylights with cardboard and tape, start with a tape measure. Measure the inside of the window shaft at the top, middle, and bottom. Most shafts are slightly flared or tapered, and you need to know the narrowest point to ensure your tracks will fit. Don't assume your builder made the opening perfectly rectangular; they almost never are.

Once you have your measurements, look for a 'honeycomb' fabric with a silver or white backing. This reflects the UV rays back out through the glass. When it comes time to install, don't be intimidated by the ceiling height. If you follow the guide on how to install your shades, you'll see that most track systems just require a few clips and a bit of patience. It’s a one-afternoon project that will save your AC bill for years.

Skylight Covering FAQ

Will blackout shades make my room too dark during the day?

Only if you leave them closed! The beauty of a tracked system is that you can stop the shade halfway. You get the 'glow' from the top half of the window while blocking the direct glare that hits your computer screen or TV.

Can I use regular curtains for a skylight?

Technically, yes, if you install a rod at the top and the bottom to create a 'stretched' look. However, the fabric will still sag in the middle over time, and it’s much harder to open and close than a dedicated skylight blind.

Do I really need motorization?

If you can't reach the window with your hand, yes. Manual poles are clunky, they scratch the paint on your window return, and they usually end up hidden in a closet because they’re a pain to use. Remote or app control ensures you actually use the shades you paid for.
