10 Year Comprehensive Guarantee

The EcoGard range of roof lights for flat roofs are manufactured to the highest standards and competitively priced. Careful attention to detail and selection of high performance sealants that last, ensure we can confidently offer a 10 year guarantee against leaks when installed within our recommendations. However, building owners can be confident EcoGard will give many years good service with a design life of 25 years or more and virtually zero life-cycle costs.

Designed for easy fixing to builder’s curb, but why not save valuable time on site and order one of our flat pack timber curbs which incorporate the necessary 5° fall? These are available in standard sizes and can be sent next day so the roof opening can be prepared prior to delivery of the roof light.​

What are the benefits of Ecoguard Flat Rooflights?

EcoGuard flat rooflights are beneficial for buildings that don’t have the necessary space to install a roof lantern. They’re incredibly easy to install and don’t require planning permission before installation. They’re aesthetically pleasing and can allow far more light into your room than a standard vertical window. They’re a great natural light solution for any residential or commercial building. 

Are Ecogard Flat Rooflights Easy To Clean?

EgoGuard flat rooflights are incredibly easy to clean. All you need is warm water, soap, a sponge, and a microfibre cloth. The warm water and soap will lift the dirt, the sponge will dislodge it from the glass surface, and the microfibre cloth will ensure a sleek and clean finish to your panes. It is important to remember to never use abrasive cleaners or sponges on your EcoGuard flat rooflight, and to avoid using a jet washer, as this can dislodge the silicone seal and make your rooflight more liable to leaking. 

Can You Walk On A Flat Ecogard Rooflight?

We manufacture our EcoGuard flat rooflights using toughened safety glass. Toughened safety glass is tested under strenuous conditions to make them suitable for walking on, and is five times stronger than regular glass. So, so long as your EcoGuard flat rooflight has toughened safety glass, you can walk on it.  

How Much Does An Ecogard Flat Rooflight Cost?

We price our rooflights competitively, so we can ensure you receive the best products for the lowest price. Our prices start from £350 and increase following your requirements. If you need a bespoke EcoGuard flat rooflight, we’ll be happy to give you a quote over the phone, as there are just too many variables to publish a cost on our website!
