How we approach conservation rooflights in Mangotsfield
Thinking about conservation rooflights in Mangotsfield? The short answer: slim, low-profile steel-look rooflights for period and listed roofs. The longer answer depends on your roof, which is why we survey before we price.
Barn and chapel conversions in the South West often need bespoke or shaped rooflights to suit the original structure. Typical uses for conservation rooflights include slate and plain-tile roofs where a quiet roofline matters.
Mangotsfield is around 46 km from Gloucester, and we survey and fit throughout that part of Gloucestershire, including the BS16 district.

Planning and building rules for Mangotsfield
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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
