How we approach pitched roof windows in Lancaster
Thinking about pitched roof windows in Lancaster? The short answer: centre-pivot and top-hung skylights for tiled and slate roofs. The longer answer depends on your roof, which is why we survey before we price.
Exposed hillside towns in the North West need flashing and seal details that cope with wind-driven rain. Pitched roof windows suit pitched roofs over bedrooms, stairs and bathrooms.
Lancaster is around 32 km from Preston, and we survey and fit throughout that part of Lancashire, including the LA1 district.

Do you need permission in Lancaster?
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
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 I need planning permission for a roof window?
Often not, under householder permitted development, provided it does not project too far above the roof plane and conditions are met. Listed buildings, flats and some conservation areas are different. Our planning guide covers each nation.
Can you replace an old roof window?
Yes — replacement into the same opening is usually quicker than a new install, often a few hours per window.
