What do flat rooflights in Shrewsbury involve?
Flat rooflights in Shrewsbury means fixed double or triple glazed rooflights for flat roofs and extensions. We cover the SY1 district and the rest of Shropshire, with a survey before any price is fixed.
Bungalows are common across parts of the Midlands, and sun tunnels or roof windows are a quick way to brighten internal hallways. Flat rooflights suit landings, bathrooms and rear extensions with flat roofs.
Shrewsbury sits about 16 km from Wellington and 21 km from Telford, and we cover the whole SY1 postcode district and the roads in between.
What you can choose
- Frame colours: anthracite, black, white or RAL
- Solar-control or self-cleaning outer pane
- Square, rectangular or long-format sizes
- Insulated kerb or timber upstand built to suit
- Double or triple glazing
- Inner pane laminated for safety overhead
- Pairs with an opening unit where you also need ventilation
Before you order: points to check
- The roof membrane must be dressed up the upstand before the unit goes on
- Needs a properly formed upstand — usually at least 150 mm above the finished roof surface (check the manufacturer's figure)
Planning, building control and Shrewsbury
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.
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.

Questions about flat rooflights in Shrewsbury
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 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.
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 work alongside my builder in Shrewsbury?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Is the survey in Shrewsbury free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
