What do dome rooflights in Coleraine involve?
We handle dome rooflights across County Londonderry, including Coleraine. In short: polycarbonate and acrylic domes for flat roofs, new or replacement. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Wind and rain off the Atlantic make upstand and flashing details important on Northern Irish roofs. In Coleraine, as anywhere, dome rooflights are the usual choice for older flat roofs with yellowed or leaking domes.
Coleraine is around 44 km from Derry/Londonderry, and we survey and fit throughout that part of County Londonderry, including the BT51 district.
Options we can specify in Coleraine
- Twin, triple or quad skin
- Insulated PVC or GRP upstands

What to check first
- Upstand condition decides whether you replace dome only or the whole unit
- Old domes may be fragile — treat as fragile until checked
Building control and safety duties in Coleraine
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 non-domestic buildings in Northern Ireland, Technical Booklet F2 covers energy performance; we supply the manufacturer's data for building control. Fire classification of rooflight materials near boundaries is checked at specification.

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