Common questions
How much does a tiled conservatory roof cost?
A solid insulated tiled roof on a standard 3m by 3m conservatory typically costs £6,000 to £8,500 supplied and fitted, rising to £11,000 or more on a larger 4m by 4m.
Do I need building regulations to replace a conservatory roof?
Usually yes for a solid tiled roof, as it makes the room permanent. Approval commonly adds £400 to £800. A like-for-like glass or polycarbonate swap normally does not need it.
Is it worth replacing a conservatory roof?
If the room is unusable in summer and winter, a roof swap is much cheaper than replacing the conservatory. A solid insulated roof at £6,000 to £12,000 turns it into a genuine year-round room; new glass at £2,500 to £5,500 is the middle ground. Set the cost against what the conservatory is worth to you as usable space: on a tired frame, spending £10,000 on the roof alone can be money in the wrong place.
What is the cheapest way to replace a conservatory roof?
A like-for-like polycarbonate swap at £2,000 to £4,000. It fixes leaks and tired panels but does little for temperature, so it suits a conservatory used three seasons a year. If heat and cold are the actual complaint, the extra for glass or a solid roof is what solves it.
Can I replace a conservatory roof myself?
A basic polycarbonate swap at £2,000 to £4,000 is the only version a confident DIYer might tackle, saving mainly on fitting. A glass roof at £2,500 to £5,500 or a solid tiled roof at £6,000 to £12,000 is a different job, with structural loading, weatherproofing and often building regulations. Get those wrong and you get leaks or a sagging frame, so pay a fitter for anything beyond a like-for-like panel change.
How long does a conservatory roof last?
It depends entirely on which of the three you have. Polycarbonate is the shortest-lived at roughly 10 to 15 years before it discolours, gets noisy in rain and stops controlling temperature; some panels keep going to 20 but perform poorly well before that. Glass roofs are generally quoted at 20 to 25 years for the sealed units, though estimates vary and a unit that has misted has failed whatever its age. A solid insulated tiled roof is the long-term answer at 40 to 50 years or more, which is part of why it costs several times a like-for-like swap. Worth knowing that the roof almost always fails before the frame and base, so replacing the roof on a sound conservatory is usually better value than replacing the whole thing.
Does a new conservatory roof add value to your home?
It rarely returns the full outlay, but a solid tiled roof at £6,000 to £12,000 can make a cold, unused conservatory into a room people actually count, which helps a sale. A cheaper glass or polycarbonate roof at £2,000 to £5,500 mostly buys comfort and lower glare while you live there. Treat it as improving usable space rather than money back on resale.
