Bespoke & shaped rooflights in Hertford: what is involved?
Thinking about bespoke & shaped rooflights in Hertford? The short answer: triangular, angled, curved and multi-pane rooflights made to measure. The longer answer depends on your roof, which is why we survey before we price.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. In Hertford, as anywhere, bespoke & shaped rooflights are the usual choice for openings that standard sizes do not fit.
Jobs in Hertford are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Choices for your Hertford project
- Concealed or slim frames
- Multi-pane butt-jointed runs
- Solar-control and low-iron glass
- Sloped or monopitch rooflights
- Triangular and trapezoid panes
- Glass shaped to the architecture
- Matching solar and thermal performance
Things we check at survey
- Large panes need a lifting plan
- Structural support must be designed in
Do you need permission in Hertford?
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. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
See our building regulations guide for U-values, glazing limits and self-certification.
