Flat rooflights for Stockton-on-Tees: the essentials
Flat rooflights in Stockton-on-Tees means fixed double or triple glazed rooflights for flat roofs and extensions. We cover the TS19 district and the rest of Durham, 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. Typical uses for flat rooflights include landings, bathrooms and rear extensions with flat roofs.
From Stockton-on-Tees to Billingham, Thornaby-on-Tees and Middlesbrough, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning, building control and Stockton-on-Tees
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. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
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.
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.
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.
Will I need planning permission in Stockton-on-Tees?
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.
How do I book a survey in Stockton-on-Tees?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
