Dome rooflights in Altrincham: what is involved?
We handle dome rooflights across Greater Manchester, including Altrincham. 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.
Exposed hillside towns in the North West need flashing and seal details that cope with wind-driven rain. Typical uses for dome rooflights include schools, flats and commercial flat roofs.
Neighbouring towns include Sale (4 km) and Urmston (7 km). We offer a survey date when we reply to your enquiry.

Building control and safety duties in Altrincham
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. We confirm the route for your building before ordering.
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
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 domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes it.
Can domes open?
Hinged and vented domes are available, manual or electric.
