How we approach pitched roof windows in Grantham
Our pitched roof windows service in Grantham covers centre-pivot and top-hung skylights for tiled and slate roofs. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Industrial and commercial units around Midlands towns often still have their original rooflight sheets, which are due for replacement. Pitched roof windows suit pitched roofs over bedrooms, stairs and bathrooms.
From Grantham to Newark-on-Trent, Melton Mowbray and Oakham, the same survey-first process applies: measure, specify, fix the price, then fit.

Do you need permission in Grantham?
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. 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.

Common questions
Centre-pivot or top-hung?
Centre-pivot windows are easy to clean and suit most rooms. Top-hung windows open out from the top for an unobstructed view and suit lower roof pitches near eye level.
Can roof windows be electric?
Yes — electric and solar-powered models open by remote and many include rain sensors.
Can a roof window be fitted from inside?
In most cases, yes — only the tiles around the opening are lifted, and much of the work is done from inside the loft.
Do you fit pitched roof windows in Grantham?
Yes. We survey and fit pitched roof windows in Grantham and across Lincolnshire. Send your postcode and we will offer a survey date when we reply.
Can you work alongside my builder in Grantham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
