What do dome rooflights in Letchworth Garden City involve?
Thinking about dome rooflights in Letchworth Garden City? The short answer: polycarbonate and acrylic domes for flat roofs, new or replacement. The longer answer depends on your roof, which is why we survey before we price.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Typical uses for dome rooflights include schools, flats and commercial flat roofs.
We work across Hertfordshire, including Letchworth Garden City, and in neighbouring towns such as Hitchin and Stevenage. Access, parking and how the glass reaches the roof are all checked at the survey.

Before you order: points to check
- Upstand condition decides whether you replace dome only or the whole unit

Building control and safety duties in Letchworth Garden City
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. Fragile-roof safety and access are planned before work starts.
Read the planning permission guide before you commit to a design.

Questions about dome rooflights in Letchworth Garden City
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.
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.
Do I need to be at home for the survey in Letchworth Garden City?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Letchworth Garden City?
