Bespoke & shaped rooflights for Hatfield: the essentials
Thinking about bespoke & shaped rooflights in Hatfield? 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.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. In Hatfield, as anywhere, bespoke & shaped rooflights are the usual choice for openings that standard sizes do not fit.
From Hatfield to Welwyn Garden City, St Albans and Potters Bar, the same survey-first process applies: measure, specify, fix the price, then fit.
What you can choose
- Multi-pane butt-jointed runs
- Triangular and trapezoid panes
- Concealed or slim frames
- Sloped or monopitch rooflights
- Corner and wrap-around glazing
- Matching solar and thermal performance
- Structural or framed options
What to check first
- Structural support must be designed in
- Longer lead times and no returns on made-to-measure glass
Planning and building rules for Hatfield
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. 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.
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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.
