How To Clean Roof Lanterns


Natural light does wonders for the atmosphere in the home. It can make rooms feel light and airy and roof lanterns are a great way to maximise it. After all, the sun is above us, so placing glazing on the roof will bring all that sunshine directly into your home. Roof lanterns and roof lights are also stylish and attractive, and can even increase the value of a property.

As with all things, you have to clean them if you want them to look their best. At some point, they’ll accumulate airbourne dirt and bird mess, and you’ll need to put some work in to get them sparkling again. But what’s the best way to do this? There are a few differences between cleaning a roof lantern and a regular window. Here’s what you need to do.

Roof Lantern Cleaning Guide

The biggest obstacle to cleaning a roof lantern is its unique shape. The average roof lantern is triangular and giving it a good scrub can be awkward, especially on the inside. You’ll most likely have to set up a step ladder underneath it, so we’d recommend having someone else with you to hold it steady. Additionally, make sure the area directly under your lantern is clear and consider stretching an old towel across the floor. Gravity is not on your side, and any water or cleaning spray you use is going to slide down the lantern and drip onto the floor.

Once the surrounding area is clear and you can trust your ladder not to fall out from under your feet, climb up and use a duster to remove any cobwebs. Then gently wipe down the glass with a non-abrasive sponge and some warm soapy water. Wipe away any dirt and if you encounter any stubborn bits, apply some elbow grease until it’s gone. Keep any nearby windows open and allow the lantern to dry.

It doesn’t take too long to do this and is a classic “boring Sunday afternoon” job. Generally speaking, the interior is the trickier part, but it doesn’t need cleaning as much as the outside. Speaking of which…

Washing The Outside

Because it’s exposed to the elements, the external side of the lantern gets dirty easier than the inside. However, from our perspective, it’s the simpler part. You’re not lifting wet cloths overhead and having water drip into your face, gravity is on your side this time.

The bigger concern is whether or not your roof will support your weight. Generally speaking, you should be fine but if in doubt, hire a professional rather than climbing up yourself. We’d also suggest doing this on an overcast day, as the glass will dry slower and you’re less likely to get any unsightly streaks forming on it.

Just like indoors, cleaning the roof lantern only requires a non-abrasive sponge and some warm soapy water. Don’t worry about scrubbing too hard, the aluminium frame is incredibly sturdy and built to last. As you’re outside, you can also rinse them off with a hose at the end and remove any lingering grime.

Keeping your roof lantern at its most attractive isn’t too taxing and it certainly requires no specialist knowledge. Modern life can be very hectic though and the hardest part is finding the time. If that’s the case, you can always hire a professional service instead of doing it yourself.
