Glass links & glass box roofs for Grays: the essentials
Our glass links & glass box roofs service in Grays covers frameless glass links joining old and new buildings. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Flat, open landscape in much of the East means roofs take the wind, so upstand and seal details matter more than the brand of glass. Glass links & glass box roofs suit joining a period house to a new extension or annexe.
We work across Essex, including Grays, and in neighbouring towns such as South Ockendon and Gravesend. Access, parking and how the glass reaches the roof are all checked at the survey.

Do you need permission in Grays?
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.

Glass links & glass box roofs in Grays: questions
How is the glass joined to the old wall?
Usually by a slim channel or flashing set into the masonry, sealed and weathered so the old wall can move without cracking the glass seal.
Can a glass link be warm enough to use all year?
With insulated glass units, solar control and good detailing, yes — though it will always be brighter and more exposed to temperature swings than a solid room.
How long does a link take?
Design and manufacture are the long part. Fitting is often two to five days.
Is the survey in Grays free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Will I need planning permission in Grays?
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line.
