Frequently Asked Questions

What Are Flat Roof Windows?

A flat roof window is a type of skylight or roof lantern that is designed to be fitted in properties with flat roofs. Depending on the type of roof window we are discussing, each unit may consist of a simple square or rectangular frame with polycarbonate, Opalite or acrylic glazing.

How Much Do Flat Rooflights Cost?

The cost of a flat rooflight depends on the type and size you order, as well as the options you choose. To find out how much a specific size and model costs, please proceed to the relevant product page and choose your preferred options, together with the overall size that you require. If it is one of the rooflights that is made to custom sizes, we ask you to use the contact form to send us a message, letting us know your desired dimensions.

Can I Install Skylights if My Roof Is Not Flat?

If you have a property with a pitched roof, you can still install roof windows in it, just not those designed for flat roofs. There are special skylights that are designed to be installed in pitched roofs. Most of them open and close, either with the window spinning around a central axis (centre pivot) or being attached to a hinge at the top of the frame.

Should I Fit Round, Square or Rectangular Rooflights?

The choice of round, square or rectangular rooflights is primarily a matter of personal preferences and tastes in interior/exterior décor although you should, of course, also consider the style of your property. Certain interior décor themes and exterior architectural design features may complement round rooflights whilst others will look better with square or rectangular units. In general, round roof windows are more suited to smaller rooms such as bathrooms or kitchenettes whilst larger, square or rectangular, units are a better choice for main reception rooms and master bedrooms.

What Is the Difference Between Skylights and Roof Lanterns?

Whilst both skylights and roof lanterns are types of flat roof windows, they are not the same thing. Roof lanterns are more ornate fixtures, normally pyramid-shaped, and are often fitted to older properties and homes with more traditional exterior designs. Skylights feature flat panes of Opalite/glass, acrylic or polycarbonate and are suitable for all types of properties with flat roofs. Having said that, they are most often fitted in contemporary homes as their clean lines and flat surfaces blend in well with modern architectural styles.
