Our flat roof dome windows are a durable and practical glazing solution designed to deliver excellent natural daylight on flat roofs, particularly where roof pitch is low or minimal. Commonly referred to as domed rooflights, these units are ideal for both residential and commercial applications where reliable performance and long-term durability are essential.
At Trusted Building Supplies, we offer a wide range of flat roof dome windows in fixed, manual opening and electric opening designs. Manufactured using tough polycarbonate domes and high-performance glazing, these rooflights provide a dependable solution for everyday flat roof use.
Fixed Flat Roof Dome Windows
Fixed flat roof dome windows are ideal where ventilation is not required but maximum daylight is needed. The raised dome profile allows light to enter from multiple angles while encouraging effective rainwater run-off, making these rooflights particularly suitable for corridors, stairwells, storage areas and commercial spaces.
Manual & Electric Opening Dome Rooflights
Manual and electric opening flat roof dome windows provide controlled ventilation alongside natural light, helping to improve airflow and indoor comfort. Manual options offer simple, reliable operation, while electric dome rooflights add convenience with remote control functionality and features such as automatic rain sensors.
Designed for Low Pitch & Zero Pitch Roofs
One of the key advantages of domed rooflights is their suitability for low pitch and zero pitch flat roofs. The curved dome design improves water run-off and reduces the risk of standing water around the roof opening, helping to maintain long-term performance even in demanding conditions.
Durable & Secure Construction
Flat roof dome windows are typically manufactured with impact-resistant polycarbonate domes and double glazed security units. Many options include laminated anti-burglary glass, UV protective coatings, and insulated kerb upstands, offering a strong balance of security, energy efficiency and longevity.
