What do dome rooflights involve?
Dome rooflights in Essex means polycarbonate and acrylic domes for flat roofs, new or replacement. Every quote follows a survey of the roof and the room below.
Flat, open landscape in much of the East means roofs take the wind, so upstand and seal details matter more than the brand of glass. Barn conversions and timber-framed homes across the East often call for conservation rooflights or bespoke glass.

Planning and building rules in England
For non-domestic buildings, planning depends on the building and its location; building regulations cover thermal performance and the fire classification of rooflights near boundaries. 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.

Common questions
Why has my dome gone yellow?
UV breaks down older plastics over time. Modern domes have UV-protective layers, but all plastics age.
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.
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
Do you fit dome rooflights across Essex?
Yes. We survey and fit dome rooflights across Essex, including Southend-on-Sea, Basildon, Colchester.
