Rooflights in flat roofs across Staffordshire

Across Staffordshire, as everywhere, most rooflight leaks start at a low or poorly finished upstand rather than at the glazing. When we fit a rooflight or lantern as part of a flat roof job, the opening, the kerb, the membrane and the joint with the frame are all done together and checked before we leave.

Which flat roofs are common in Staffordshire?

Flat roofs in Staffordshire sit on terraced streets with flat-roofed rear kitchens and bathrooms, low-rise post-war blocks of flats and bungalows with flat-roofed side extensions and dormers. England averages roughly 870 mm of rain a year and the West Midlands sits close to that, so falls and outlets are the difference between a roof that drains and one that ponds. Approximate 1991–2020 regional averages based on Met Office data.

Building regulations in England

Replacing more than half of a roof over a heated room usually counts as renovating a thermal element, so it is insulated to current standards and notified to building control. Renovated roofs over heated rooms are insulated to around 0.16 W/m²K where that's feasible, and new extension roofs are built to 0.15 W/m²K. In Staffordshire the application goes to Stoke-on-Trent City Council, Newcastle-under-Lyme Borough Council, East Staffordshire Borough Council and 6 other councils. More on the rules.

Should I choose a fixed or an opening rooflight, or a lantern?

Choose a fixed rooflight if you only want daylight, an opening one if the room needs ventilation, and a lantern if you want a raised, pitched glazed feature over a larger space.

  • Fixed flat rooflights are the simplest and usually the cheapest option. They have the fewest moving seals, and the upstand detail is straightforward.
  • Opening rooflights can be manual or electric, and electric units often include a rain sensor that closes them automatically. They need a power supply planned in before the ceiling is finished. Some are designed as hatches to give access to the roof.
  • Roof lanterns have a framed, pitched glazed top that brings in more light and adds height to the room. They are heavier and larger, so the upstand has to be strong, level and square, and the joists around the opening may need strengthening.

Whatever you choose, it helps to settle on the unit before the roof is built, so the upstand can be made to the maker's sizes. If you've already chosen one, we build the upstand to suit it.

How long does a rooflight upstand last?

A properly built, insulated upstand with waterproofing dressed to the maker's details should last as long as the roof covering around it. The rooflight's own seals and opening parts may need attention sooner.

Upstands fail early when they are too low, poorly insulated or built on a deck that moves. Keeping the area around the rooflight clear of leaves and debris, checking the corners after storms from a safe position and cleaning the glazing gently all help. Never lean on or stand on a rooflight: most are fragile, and the roof around them should be treated as fragile too. The maintenance guide covers routine checks.

Can a lantern go on a warm roof?

Yes. The upstand is built and insulated to the full height of the warm roof build-up, so the lantern sits at the right level above the finished surface.

Do you supply rooflights and lanterns?

We fit rooflights and lanterns as part of a flat roof job, but we don't sell them as a separate product. If you've chosen a unit, we'll build the upstand to suit it.

Can I walk on a flat rooflight?

No, unless it is a unit specifically designed and rated for foot traffic. Treat standard rooflights and the roof around them as fragile.
