Temporary Fix for a Leaking Skylight


Look, skylights are a sight for sore eyes, aren’t they? They let in a buffet of natural light during the day and give you a view of the stars when the lights go out. It’s like having a window seat to the big cosmic show. 

But—and there’s always a but—when they start leaking, they can become quite a headache. To handle a leaking skylight effectively, you need to get to the root of the problem before you can apply a fix. The culprit? It could be many things, so let’s see what we’re dealing with.

Determine the Source of the Leaking Skylights

Now, folks, don’t just dive in to fix that leak before figuring out the why behind what’s going on. Understand that sometimes, the source of leakage might not be as blatant as a faulty skylight. Heck, it might not even be the skylight but poor roof installation. 

Water is sneaky like that; it collects at certain points, causing your pristine ceiling to bloom with water spots. Finally, remember that cracks are unfaithful partners; they could appear on the roof or where the roof and the skylight meet, but either way, they need to be dealt with as soon as possible, lest they turn your home into an indoor rainforest.

Hole On Roof

Holes on the roof are the most notorious crooks in the gang of leaks. Look for missing or damaged shingles on the roof. These cute little fellows are lying snug on your roof; if lost, they’re leaving your roof more exposed. Fix that, and you’ve got one less thing to worry about.

Broken Seal

The seal – is often neglected but is still a vital piece of the puzzle in our hunt for the source of the leak. When intact, it’s just doing its job without anybody noticing. But let the broken seal have the day off, and we’re dealing with moisture dripping between the window casing and the frame. So, keep an eye on that seal. 

Weathered Seals

I’m not saying your skylight is old, but if its seals have seen better days, they might be the culprits. Weathered seals often lead to water dripping between the window casing and the frame.

Unclosed skylight

Pardon me for stating the obvious, but if the skylight isn’t closing, that’s your problem right there. It’s like leaving your front door wide open and wondering why the bugs get in.

Bad Insulation

Your skylight might be perfectly fine, but if the insulation around it fumbles the ball, get ready to deal with the leakage. The skylight’s beauty is only skin deep, but the insulation beneath, my friend, isn’t just fluff. It’s the armour that prevents water from breaching your castle. Ignore it at your peril.

A Crack in the Frame

Last but not least, let’s not forget about a possible crack in the frame. You see, the frame is like the skylight’s backbone, and any cracks on the sides may let in a torrent. 

How to Temporarily Repair a Leaking Skylight

Listen up, folks, we’re treading in the murky waters of skylight repairs here. It’s got its hazards, dangers, and slippery slopes, but lucky for you, we’ve got a temporary solution. Now, these aren’t foolproof and won’t hold back the tide forever, but they should come in handy for combating immediate crises, like a leak in the middle of a thunderstorm. Let’s roll up our sleeves and dive right in.

Use A Sealant

Fixing a leaky skylight could be as simple as plugging it up, just like you’d slap a band-aid on a skinned knee. Silicone sealants are like the duct tape of the repair world, useful for fixing everything and anything. Give the area around your skylight a smack with this stuff; that leak should hold its horses for a while.

Apply it liberally; don’t be shy. You might need a pro to deal with it for a more permanent fix. But this should work for the time being.

Replace Roof Flashing

Up next on our sleight-of-hand repair guide is replacing the flashing around your skylight. Flashing is like an umbrella for your skylight, steering the rainwater away. Check for things like obvious damages, open seams, and signs of failed repairs in the past. When you finally break out that roof cement, be sure to cover all the bases. Smear it on generously and make sure no nook or cranny is left exposed.

Replace the Seals

It’s time to talk about the unsung heroes in the fight against leaks. The seals. These champs are positioned around the edges of your skylights, preventing water from breaching. And whenever they falter, do not fret; a swift replacement will do the trick.

In fact, changing them in haste could save your day. Yeah, it might not end the war against leaks, but it’s definitely a decisive battle in your favour. Look at it this way: it’s a temporary fix, like patching up a bike tire, but it also buys you more time till that weekend sunny enough for a full-day roof repair.

Clear Roof of Debris

Finally, there is no point mending a skylight if its environs resemble the local forest. Debris cluttered around the skylight likes to party with the rainwater, teaming up to cause you problems. Just like you’d clear your garden of weeds for the tulips to bloom, sweeping the roof of debris is something you can do all by your lonesome.

Temporarily Fixing Skylights

Fixing a leaking skylight can feel like patching up a boat in the middle of a lake, but hey, a temporary solution is better than waking up to raindrops crashing your living room party. It’s about getting your hands dirty, doing what you can to stop the damage while waiting for the pros. 

A tiny drip can tell you a lot about the source of the leak. Be it seeping under the flashing or condensation failing to drain through the weep holes, those tiny holes doing wonders for ventilation, once you pinpoint the source, you’re halfway to dry land.

Reach out for your trusted tools, get that caulk gun and the appropriate sealant, or in more desperate times, resort to a glob of roofing cement. Call it a seal of approval, but that seal between the flashing and the roof deck, if properly restored, can have your skylight leakproof when installed correctly. 

Raise a putty knife in victory but keep an eye out for those skylight defects and faulty flashings. Remember, it’s a band-aid solution and you’re not aiming to replace the roofing contractors, just buying some time before bringing in the heavy artillery.
