Frequent Questions

Here are some of our frequently asked questions.

If you need further information or wish to speak to a member of our team, please do get in touch!

  • Glass rooflights on a flat roof should be a fitted to a minimum pitch of 3° to aid runoff and to stop water pooling on the unit.  Although the minimum pitch is 3° you may wish to consider a pitch of around 5° to ensure adequate runoff on larger skylights. The pitch of the unit rooflight is something that will affect your warranty so it is important to get this detail right when installing a new glass rooflight.  The minimum and maximum pitch required for rooflights differs between brands so please check individual products for more information.

  • All rooflights will require an element of cleaning as normal windows would. As a product that is fitted to the exterior of a property rooflights are susceptible to dirt debris and pollution build up which may affect the clarity of your glass skylight.  We are able to supply glass rooflights with an ‘easy-clean coating’ which can make the cleaning process easier. We would recommend thorough cleaning at least bi-annually using water and non-abrasive cleaners.  Full product specific maintenance information is available for each skylight we supply.

  • We can supply a wide variety of glass specs depending on your specific requirements.  Generally we supply double glazed laminated glass however if you need a different specification please talk to our team who will be able to advise which rooflight would best suit your design.  The majority of skylights we supply come with clear glass but other options are available on request.

  • Unless specifically quoted as a Walk On Specification rooflight then no a rooflight cannot be walked on.  A walk on rooflight is made up of a very thick glass spec (also known as class 0)so it is suitable for foot traffic, when asking for a quote for a walk on rooflight it is important to clarify if is a domestic or commercial building as this will affect the glass specification.
