Skylight leaking problems: should you really be concerned?

When we meet new customers, we often find that they have certain questions and concerns they wish to discuss before choosing their new skylights.  This is normal: everyone should take the time to be sure they’re making the right purchase, after all!  However, we’ve noticed that a few concerns tend to come up often, one of which is the potential for skylight leaking problems.


Sunsquare Limited has been innovating the UK skylight industry since 2004, pioneering bespoke skylight designs that use the highest possible specifications to encourage abundant levels of natural daylight into homes and workplaces across the globe.

The company has set the benchmark for flat roof windows by becoming the first designer and manufacturer of bespoke skylights to achieve a British Standards Institution (BSI) quality stamp.

A skylight can add a tremendous amount of natural light to any room and create the illusion of extra space. With around 165 different skylight combinations to choose from, Sunsquare works with self-builders, architects and high-end residential, commercial and public firms to transform living and working areas.

We Are Sunsquare

The UK's flat rooflight pioneers

Bespoke Skylight Project at Long House

As pioneers in the UK rooflight industry, Sunsquare products are designed and manufactured to provide outstanding thermal performance alongside their stunning aesthetic qualities. Our roof windows are made from our extruded aluminium profile which is thermally broken using multiple polyamide insulating sections. It’s therefore easy to understand why our entire BSI Kitemarked product range surpasses Building Regulations with ease.

Every single roof window, roof lantern and skylight that leaves our state-of-the-art manufacturing facility comes with a full warranty. Our products are manufactured in such a way that you can choose from a host of glazing specifications to suit your project’s unique requirements. From low maintenance and solar control glazing to privacy glazing, we can advise on the best possible solution.

We also offer our world-leading skylights in a range of stock sizes from our Suffolk-based factory; perfect for those that don’t have bespoke needs but where time is of the essence, requiring delivery or collection in just five working days.
