Rooflight upstands & kerbs for Berwick-upon-Tweed: the essentials
Rooflight upstands & kerbs in Berwick-upon-Tweed means insulated kerbs built and waterproofed to suit your rooflight. We cover the TD15 district and the rest of Northumberland, with a survey before any price is fixed.

From Berwick-upon-Tweed to Alnwick, Morpeth and Ashington, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning and building rules for Berwick-upon-Tweed
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. 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. 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.
Read the planning permission guide before you commit to a design.

Questions about rooflight upstands & kerbs in Berwick-upon-Tweed
Does every rooflight need an upstand?
Flat and dome rooflights do. Pitched roof windows use flashing kits instead.
Can I build the upstand myself?
Your builder can, to our drawing. We check it before the rooflight is fitted, because the unit must sit square and level.
How high should a rooflight upstand be?
High enough to meet the rooflight manufacturer's minimum above the finished roof surface — commonly 150 mm. On roofs with deep finishes, such as green roofs, it needs to be taller.
Is the survey in Berwick-upon-Tweed free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
How do I book a survey in Berwick-upon-Tweed?
