Spring is upon us, thank goodness!

This time of year is associated with new life and rejuvenation – it also signifies the seasonal spring clean for many. If you’re going to give your home a seasonal refresh, it means getting right into those nooks and crannies to truly welcome in the spring.

If you want to make the most of the sunshine, we recommend giving your roof lantern a little TLC. If you’re sat there thinking “well, how do I clean my roof windows?”, we’re going to break it down for you. With over 30 years’ experience, we’re experts, so you’ve come to the right place for help!

What Products Should I Use?

Firstly, it should be noted not to use any harsh chemicals, abrasive cleaners or utensils on your roof lantern. Not only could this affect the glass, it could damage the timber and paint on the structure. We recommend using a non-abrasive sponge and some lukewarm, soapy water. A little washing up liquid works a treat. You can either use a soft squeegee to eliminate drip marks, or a large microfibre cloth. Use both in a downward stoke motion to avoid smearing.

Interior Cleaning

Before you start the washing process, move any furniture which sit under your roof windows out of the way. Spread a sheet on the floor directly below to catch any dirt or spills. You can use extendable equipment or be sure to use a specialist ladder – if possible, get someone else to help guide and assist you.

Next, it’s important to remove any dust and cobwebs from the interior of your roof lantern. You certainly don’t want to be washing your windows with the dirt accumulated over the past few months! Use a feather duster to gather the excess before you start washing.

Clean the glass using your soft sponge and soapy water. You may need to apply a little pressure where you see any build-up of grime. When washed, use your squeegee and microfibre cloth in a downward motion to eliminate water marks and streaks. It’s as simple as that!

Exterior Cleaning

A very similar process to the above, but it’s essential to have someone else spotting from below, should you need help. Always use ladders correctly and with extreme care. Using warm, soapy water and a soft sponge, clean the windows and the exterior structure of your roof lantern. The surround fixings can be wiped over gently; never use hard chemicals on the timber wood as it can cause significant damage.

You may find that certain areas need a little more elbow grease than others and this is completely normal. The exterior parts of a roof lantern are more exposed to the elements, as well as tree sap, bird droppings and vehicle pollution. Leave the water to soak in for a few minutes and it should be easier to wipe away.

Never stand or lean on your roof windows. If you are not confident working at a height, we would always advise hiring a professional.

How Often Should I Clean My Roof Windows?

We would recommend cleaning your roof windows thoroughly at least every 6 months. Not only does it keep your roof windows in the best condition, but you will quickly be able to notice an abnormality in the glass, should it occur. That being said, cleaning frequency can be down to personal preference. Some clients have a window cleaner on a monthly basis. Taking care of your skylight means you will get the most out of it.

Check Your Glass

Whilst cleaning your roof windows, it’s the perfect opportunity to check the glass. Although our products are built to last, glass can be easily damaged. Give your lantern a thorough once over for chips and cracks as you’re cleaning the panels. Inspect the corner of the glass to make sure there are no hairline cracks hiding. These are likely to get bigger quickly and move inwards towards the centre of the glass.
