The thought of cleaning roof windows can be daunting. The window being on the roof gives the impression that it is out of reach. This is not always the case, and when it is, it is still possible to clean the inside of your windows yourself. If you’re that way inclined and fine on a ladder, you can still clean the outside of your roof windows yourself. Some people may have heard of self-cleaning glass, but this isn’t the best option for flat roof windows. 

Self-cleaning Glass

If your roof window has self-cleaning glass, you or your window cleaner will need to take extra precautions when washing it. The compounds in it only work when the pitch is at 30 degrees or greater. Self-cleaning glass does not eliminate the need for cleaning. Do not use the soap with dye in it, or any form of an abrasive cloth. Squeegees are a no, and you’ll want purified water. 

Just Like a Normal Window

Unless the outside of the window has the self-cleaning compounds, the roof window can be cleaned in the same way as normal windows, even if they’re too high to reach. Some people prefer to hire a professional to clean the outside of the windows. If you are fine going on a ladder and prefer to wash the exteriors yourself, treat the roof windows the same as you would with any other window unless it is self-cleaning. 

While Outside

Any fallen debris needs to be cleared from roof windows; this includes heavy snowfall. If you clean your own roof windows with the regular windows, this is the perfect time to check for damage and save yourself extra trips up the ladder. A poorly maintained roof window will leak. Don’t forget to check the flashing. 

Cleaning Windows

The interior of roof windows are cleaned in the same way as any other window and should be cleaned every two to three months. 

If you’ve never cleaned a window before, here’s how it is done. Do not clean the windows on a bright and sunny day or when it is hot. Use a little washing up liquid in a bucket of warm soapy water. Wear gloves, especially if you have dry skin or manicured nails. Starting at the top of the window, wipe with the sponge after it is has met and been rung out in the bucket of soapy water. Wipe the excess with a squeegee, also starting at the top. Wipe the squeegee as needed. Dry the glass with a microfibre cloth. To eliminate streaks, use a glass cleaner or vinegar if you don’t mind the smell. Wipe off with a glass cleaning cloth, paper towels or newspaper. Some window cleaners can damage the visible parts of the frame, so do a patch test first. 

If your roof windows are high, you’ll need to do all of this with extendable cleaning poles. A sponge mop might even reach. If cleaning a flat roof window, be prepared for drips.
