Dome rooflights for Houghton-le-Spring: the essentials
Thinking about dome rooflights in Houghton-le-Spring? 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.
North East terraces and colliery-town housing often have rear offshoots where a rooflight brightens a narrow kitchen. In Houghton-le-Spring, as anywhere, dome rooflights are the usual choice for older flat roofs with yellowed or leaking domes.
From Houghton-le-Spring to Chester-le-Street, Washington and Seaham, the same survey-first process applies: measure, specify, fix the price, then fit.

Dome rooflights in Houghton-le-Spring: questions
Do domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes it.
Are domes safe to walk on?
No. Treat any rooflight as fragile unless it is specifically certified non-fragile, and never stand on it.
Why has my dome gone yellow?
UV breaks down older plastics over time. Modern domes have UV-protective layers, but all plastics age.
Can you work alongside my builder in Houghton-le-Spring?
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 Houghton-le-Spring?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
