Leaking Conservatory Roof

If your roof is over 10–15 years old and has developed leaks, replacement is usually the better investment. Repairs fix individual points of failure, but the rest of the roof is the same age and likely to develop similar problems. Replacement solves everything at once and comes with a 10-year insurance-backed guarantee.

Seal replacements and patch repairs typically last 1–3 years on an ageing conservatory roof before new leaks appear elsewhere. A full insulated tiled roof replacement lasts decades and the tiles themselves carry a 40-year manufacturer guarantee.

We focus on complete roof replacement rather than temporary repairs. Our experience is that homeowners who invest in replacement are far happier long-term than those who keep patching an ageing roof — and the cost over five years is often lower.

In order: perished rubber seals between roof panels, cracked or brittle polycarbonate sheets, corroded ridge and hip bars, failed flashing where the conservatory meets the house wall, and blocked internal guttering. Most ageing roofs have several of these failing at once.

Yes — and quickly. A persistent leak combined with poor ventilation creates ideal conditions for mould on plaster, fabric and timber, often within weeks. Mould can trigger asthma and respiratory issues, so addressing the leak promptly matters for health, not just the building.

All conservatory roof replacements start from £6,000 fully fitted, regardless of size or shape. Final cost depends on roof shape, tile finish, number of skylights and any internal finishing. Every quote is bespoke after a free home survey.

Buildings insurance occasionally covers sudden, accidental damage (e.g. a falling tree branch), but gradual deterioration of an ageing roof is excluded by virtually every UK policy. Replacement is almost always self-funded — but it's a one-off cost rather than an ongoing problem.

Typically 2–4 days from old roof off to plastered ceiling finished. We work as a single dedicated crew so the job runs continuously and your home stays watertight throughout — even overnight.

In heavy rain, water pools faster than the existing seals and box gutters can drain it away, then finds the path of least resistance — often through the smallest gap in a perished seal. Light rain runs off before it has time to find a way in. It's a classic sign that the roof drainage is failing.

You can do the safe checks from inside: look for staining on the ceiling or wall junction, run your eye along the roof bars for drips, and check whether water appears only in heavy rain or in any shower. Do not climb onto a conservatory roof or lean a ladder against the frame — conservatory roofs are not designed to carry weight. Anything that needs eyes on the roof itself should be done from a survey.

Clearing blocked gutters and moss is maintenance, and worth doing first — sometimes that alone stops an overflow. A single perished seal or a slipped flashing on an otherwise sound, newer roof is a repair job for a glazing or roofing repair firm. Where the roof is 10–15 years old and several components are failing at once, replacement is the route that actually ends the problem. We fit replacement roofs, so we will tell you honestly at survey if what you have is a repair.
