Dome rooflights in Truro: what is involved?
Thinking about dome rooflights in Truro? 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 West towns mix Georgian and Victorian terraces with modern estates, so the right product differs street by street. Dome rooflights suit older flat roofs with yellowed or leaking domes.
We cover all of Truro and the TR1 district, and nearby Falmouth and Redruth.

Things we check at survey

Regulations for dome rooflights in Truro
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. Fire classification of rooflight materials near boundaries is checked at specification.

Common questions
Can domes open?
Hinged and vented domes are available, manual or electric.
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 work alongside my builder in Truro?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Truro?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
