Dome rooflights in Islington: what is involved?
For Islington homes and buildings we offer dome rooflights: polycarbonate and acrylic domes for flat roofs, new or replacement. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Victorian and Edwardian terraces with narrow side returns are typical of much of London, and a glass roof or long flat rooflight is the usual way to keep the back rooms bright once the return is built over. In Islington, as anywhere, dome rooflights are the usual choice for older flat roofs with yellowed or leaking domes.
We work across Greater London, including Islington, and in neighbouring towns such as Highbury and Holloway. Access, parking and how the glass reaches the roof are all checked at the survey.
What you can choose
- Insulated PVC or GRP upstands
- Twin, triple or quad skin
- Clear, opal or tinted
- Fall-through protection mesh
- Fixed or hinged with vent
- Quick replacement on existing upstands
- Low cost per unit
What to check first
- Plastic domes have a lower acoustic and thermal performance than glass
- Fire classification matters on some roofs
Rules and responsibilities in Islington
On commercial roofs the main questions are usually building control, fire classification of rooflight materials and safe access rather than householder permitted development. We confirm the route for your building before ordering.
For buildings other than dwellings, Approved Document L Volume 2 sets limiting U-values of 2.2 W/m²K for rooflights and 3.0 W/m²K for roof ventilators, including smoke vents. Fire classification of rooflight materials near boundaries is checked at specification.

Questions about dome rooflights in Islington
Are domes safe to walk on?
No. Treat any rooflight as fragile unless it is specifically certified non-fragile, and never stand on it.
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
Should I replace a dome or switch to glass?
A dome is cheaper and quick; glass gives a clear view and better performance. On a tight budget, or a commercial roof with many units, domes remain sensible.
Do I need to be at home for the survey in Islington?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
