Dome rooflights for Hounslow: the essentials
Thinking about dome rooflights in Hounslow? 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.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. Typical uses for dome rooflights include schools, flats and commercial flat roofs.
Neighbouring towns include Isleworth (1 km) and Twickenham (3 km). We offer a survey date when we reply to your enquiry.

Building control and safety duties in Hounslow
On commercial roofs the main questions are usually building control, fire classification of rooflight materials and safe access rather than householder permitted development. Product data for building control is supplied with every quote.
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.

Common questions
Are domes safe to walk on?
No. Treat any rooflight as fragile unless it is specifically certified non-fragile, and never stand on it.
Do domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes it.
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.
