Roof Plastic Domes


Roof domes are for use on flat roofs, and provide maximum daylight. They provide the ideal solution when conventional windows and

roof windows cannot provide adequate daylight or ventilation. Manufactured in virtually indestructible double (or treble) skinned polycarbonate, The Loft Shop roof domes are available from stock for next day delivery in a wide range of sizes.

Our roof domes are available in square, rectangular, circular and pyramid shapes, with opening, access and ventilating options. They are installed using pre-formed flashings, or upstands, which combine with existing roof coverings. A range of accessories such as blinds are also available.
