Sliding rooflights in Northwich: what is involved?
Sliding rooflights in Northwich means box rooflights whose glass lid slides back for walk-out roof access. We cover the CW9 district and the rest of Cheshire, with a survey before any price is fixed.
Exposed hillside towns in the North West need flashing and seal details that cope with wind-driven rain. In Northwich, as anywhere, sliding rooflights are the usual choice for walk-out access where a hatch would feel cramped.
Neighbouring towns include Winsford (7 km) and Warrington (15 km). We offer a survey date when we reply to your enquiry.

Planning and building rules for Northwich
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
See our building regulations guide for U-values, glazing limits and self-certification.
