Martin · Answer

A leaking conservatory roof should be investigated as soon as possible, as water ingress can often cause more damage than is immediately visible. The first step is to identify where the water is entering, as the visible leak inside the conservatory is not always directly below the actual fault.
Common causes include failed roof seals, deteriorated glazing bars, damaged or slipped roof panels, blocked drainage channels, failed flashing where the conservatory meets the house, cracked roof sheets, or ageing roofing materials. In older conservatories, seals and fixings can deteriorate over time and allow water to penetrate during heavy rain or wind-driven weather.
The cost of repair depends on the cause of the leak. A minor repair, such as replacing seals or fixing flashing, may be a few hundred pounds, while larger repairs involving roof panels or a complete conservatory roof replacement will cost more.
A proper inspection is important before deciding on a repair because simply sealing the visible area may only provide a temporary solution. The roof structure, drainage, junctions and surrounding areas should all be checked to find the real cause.
My advice is to use an experienced roofing contractor who can diagnose the problem correctly and explain whether a repair or replacement would provide the best long-term solution. A quality repair should not only stop the leak but also prevent future water damage and give you peace of mind.

First step: identify the exact leak source before spending money.

Common causes:
	•	Failed glazing seals
	•	Slipped roof panels
	•	Perished rubber gaskets
	•	Blocked box gutters
	•	Failed flashing where it meets the house

Start with:
	1.	Visual inspection during rain if possible
	2.	Check and clear gutters
	3.	Inspect seals and joints

Typical repair costs (UK):
	•	Minor reseal: £80–£250
	•	Panel adjustment/reseal: £150–£400
	•	Box gutter clean & seal: £150–£500
	•	Replacement roof panels: £300–£1,000+
	•	Full warm roof replacement: £3,000–£7,000+

Best value step is a proper leak diagnosis before agreeing to any major work.

The most common leaks on a conservatory roof will be either the flashing or from one of the seals. the cost would depend on where the leak is.
