Flat rooflights for Smethwick: the essentials
Flat rooflights in Smethwick means fixed double or triple glazed rooflights for flat roofs and extensions. We cover the B66 district and the rest of the West Midlands, with a survey before any price is fixed.
Older terraced streets in Midlands towns often have back additions and side passages that suit a ridge rooflight or long flat rooflight. Flat rooflights suit landings, bathrooms and rear extensions with flat roofs.
From Smethwick to West Bromwich, Birmingham and Halesowen, the same survey-first process applies: measure, specify, fix the price, then fit.
Options we can specify in Smethwick
- Insulated kerb or timber upstand built to suit
- Integral or fitted blinds
- Square, rectangular or long-format sizes
- Rain sensor if paired with an opening unit
- Solar-control or self-cleaning outer pane
- Fixed units are simple, quiet and low-maintenance
- Pairs with an opening unit where you also need ventilation
Things we check at survey
- The roof membrane must be dressed up the upstand before the unit goes on
- Rooflights count toward glazing in an extension, which matters for Building Regulations energy and overheating rules
Do you need permission in Smethwick?
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. 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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
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.
Double or triple glazing?
Double glazing suits most domestic jobs. Triple glazing improves thermal performance and cuts noise from rain, which is worth it over bedrooms or where the energy calculation is tight.
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.
Do I need to be at home for the survey in Smethwick?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Will I need planning permission in Smethwick?
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.
