What do dome rooflights in Westbury-on-Trym involve?
Our dome rooflights service in Westbury-on-Trym 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.
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.
From Westbury-on-Trym to Redland, Clifton and Bristol, the same survey-first process applies: measure, specify, fix the price, then fit.

Dome rooflights in Westbury-on-Trym: questions
Why has my dome gone yellow?
UV breaks down older plastics over time. Modern domes have UV-protective layers, but all plastics age.
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 I need to be at home for the survey in Westbury-on-Trym?
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 Westbury-on-Trym?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
