How we approach dome rooflights in Morden
Our dome rooflights service in Morden covers polycarbonate and acrylic domes for flat roofs, new or replacement. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Typical uses for dome rooflights include schools, flats and commercial flat roofs.
Morden is around 13 km from central London, and we survey and fit throughout that part of Greater London, including the SM4 district.

Building control and safety duties in Morden
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about dome rooflights in Morden
Can domes open?
Hinged and vented domes are available, manual or electric.
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.
Do I need to be at home for the survey in Morden?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
