Flat rooflights in Blyth: what is involved?
Flat rooflights in Blyth means fixed double or triple glazed rooflights for flat roofs and extensions. We cover the NE24 district and the rest of Northumberland, with a survey before any price is fixed.
North East terraces and colliery-town housing often have rear offshoots where a rooflight brightens a narrow kitchen. In Blyth, as anywhere, flat rooflights are the usual choice for landings, bathrooms and rear extensions with flat roofs.
We cover all of Blyth and the NE24 district, and nearby Ashington and Cramlington.
Choices for your Blyth project

Things we check at survey
- The roof membrane must be dressed up the upstand before the unit goes on
- New openings in an existing roof need a structural check on joists
Consents for flat rooflights in Blyth
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.
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. 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.

Common questions
Can you fit into my existing flat roof?
Yes. We form a new opening, trim the joists, build and waterproof an upstand and make good the ceiling. A survey confirms the joist direction and roof build-up first.
Can a flat rooflight be walked on?
Not unless it is designed as a walk-on unit with structural laminated glass. A standard flat rooflight is for light only — if the roof is used as a terrace, choose a walk-on rooflight instead.
Will it make the room too hot?
A big unglazed-to-sky area can add solar gain in summer. Solar-control glass, a blind, or pairing a fixed unit with an opening one keeps it comfortable.
Can you work alongside my builder in Blyth?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Is the survey in Blyth free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
