Choices to weigh up in Smethwick

Solid tiled replacement roof

A lightweight insulated roof system with tiles or slate-effect tiles outside and a plastered ceiling inside, often with spotlights. It keeps the room warmer in winter and cooler in summer and cuts rain noise. The existing frames and base must be checked, and the work is notified to building control because the structure changes.

Glass replacement roof

Modern double-glazed roof panels with solar-control and self-cleaning coatings replace tired polycarbonate while keeping the room bright. It's a lighter change than a tiled roof, usually costs less and keeps the conservatory's character. It's a good choice if you mainly use the room in spring, summer and autumn and want daylight first.

How much should you budget in Smethwick?

Expect to budget between £3,500 and £22,000 depending on size and specification in Smethwick. Insulated tiled roof replacing polycarbonate on a 3.5 × 3 m conservatory: typically £7,000–£10,500.

Questions about conservatories in Smethwick

Should the doors between the house and conservatory stay?

If you want the conservatory to stay exempt from building regulations, yes. Removing them, or leaving the opening permanently open, means it must meet the full energy standards for an extension, which usually involves more insulation, glazing upgrades and an application. If you want an open-plan link, we'll talk through the extension route instead.

How do I book a survey in Smethwick?

Send the form on this page, use the guide-price tool or call 0800 088 6248 free. We'll ask a few questions about your conservatory and arrange a time to visit.

How long does a conservatory roof replacement take?

Most replacement roofs take three to seven days on site, depending on size and whether the frames need reinforcing. The roof is usually off and the new structure weathertight within a day or two, and the rest of the time goes on tiling, plastering and finishing. A new conservatory takes longer, usually two to four weeks.

Will I need permission from the council in Smethwick?

Often not. Many porches and conservatories meet the permitted development and Building Regulations exemptions. If yours doesn't, the planning authority for Smethwick is Sandwell Council.
