Flat rooflights for Hornsea: the essentials
We handle flat rooflights across the East Riding of Yorkshire, including Hornsea. In short: fixed double or triple glazed rooflights for flat roofs and extensions. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Converted barns and mills in Yorkshire often suit bespoke or ridge rooflights that follow the original structure. In Hornsea, as anywhere, flat rooflights are the usual choice for landings, bathrooms and rear extensions with flat roofs.
We work across the East Riding of Yorkshire, including Hornsea, and in neighbouring towns such as Beverley and Bridlington. Access, parking and how the glass reaches the roof are all checked at the survey.
Options we can specify in Hornsea
- Integral or fitted blinds
- Rain sensor if paired with an opening unit
- Insulated kerb or timber upstand built to suit
- Solar-control or self-cleaning outer pane
- Double or triple glazing
- Slim sightlines from inside — mostly glass, little frame
- Double or triple glazed with a warm-edge spacer
Before you order: points to check
- New openings in an existing roof need a structural check on joists
- The roof membrane must be dressed up the upstand before the unit goes on
Consents for flat rooflights in Hornsea
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. 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.

Flat rooflights in Hornsea: questions
Do flat rooflights leak?
A well-fitted flat rooflight should not leak. Leaks almost always come from the upstand or membrane detailing, not the glass unit, which is why the upstand height and the way the roof covering is dressed up and under the frame matter more than the brand.
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.
How long does it take?
Fitting into a prepared upstand usually takes a day. Forming a new opening in an existing roof, including making good inside, is often two to three days.
How do I book a survey in Hornsea?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Is the survey in Hornsea free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
