We’ll carry out a careful inspection, show you what’s causing the problem, and recommend the quickest, most cost-effective repair so you can get back to enjoying the open road.

Why Is My Convertible Leaking?
Leaks in a cabriolet are frustrating and, unfortunately, a common issue, especially in the winter periods.
Some leaks may only appear when it rains heavily, while others might become apparent when washing your car. Most start small (a drip or damp patch) and get worse over time, so it’s worth checking sooner rather than later. Below are the key signs of water ingress we typically see:
- Worn or Perished Seals & Gaskets: Rubber seals around the hood, windows, and doors harden and crack with age, letting water in.
- Clogged or Collapsed Drain Tubes: Convertibles use drains around the roof edges; if they’re blocked by leaves or dirt, water backs up into the interior.
- Torn or Damaged Soft Top Fabric or Vinyl: Rips, holes, or seam failures let rain straight through.
- Fabric Hood Has Become Porous: Over time, a hood can begin to absorb water rather than repel it.
- Misaligned Frame or Poor Hood Fit: If the folding frame isn’t sitting correctly, the hood won’t seal properly.
- Failing Rear-Window or Glass Seals: Bonded or stitched rear windows can degrade and leak where they meet the hood.
- Incorrect Use of a Pressure Washer: Using a pressure washer on convertible tops can force water into seals and seams, causing avoidable leaks.
Once the cause has been assessed, we’ll provide a tailored solution to fix the problem and prevent the same issue from happening again!

Our Water Leak Repair Services for Convertibles

When you’ve arranged a visit to our workshop, our experienced technicians carry out a comprehensive inspection to accurately identify the source of any water ingress. Drawing on expertise across a wide range of convertible makes and models, we tailor each inspection to your specific vehicle to ensure precise, effective results.
If your interior has been affected by a severe leak, we may be able to assist with restoration and repairs to return your cabin to its original condition.
Wherever possible, we focus on repairing rather than replacing components, helping you resolve the issue efficiently and cost-effectively without the need for a new roof.
Soft Top Convertible Repairs
If your soft top is leaking, we’ll inspect the material for wear, check the roof seals, and make sure the drainage channels are clear.
Soft top convertible roofs need regular maintenance and cleaning to stay waterproof and in good condition. Regular cleaning with specialist products ensures dirt doesn’t build up in seals, and applying a water-repellent treatment helps the hood maintain its protective properties. We can provide further advice on this, should you need.
Hard Top Convertible Repairs
Hard-top convertibles can also suffer from water ingress, particularly around seals and joints where the roof panels meet. Over time, the seals between panels can wear, resulting in leaks when it rains or when water runs over the roof during a car wash.
Our convertible specialists are highly experienced in hard top roof repairs. We can identify weak points in the seals and treat them to prevent further leaks.

Tips for Preventing Convertible Water Leak Issues
Prevention beats repair – especially with convertible roofs. A few simple checks and small habits will keep your hood sealing properly and stop small drips from turning into expensive damage:
Inspect Seals Regularly:
Look for cracks, hardening, or gaps where the roof meets the body. If seals are drying out, treat them with a silicone-based conditioner to keep the rubber flexible.
Keep Drainage Channels Clear:
Clear dirt from gutters and drain tubes. A quick monthly check (and after heavy rain) prevents water from backing up into the car’s interior.
Don’t Use a Pressure Washer on the Roof:
High pressure can force water into seams and joints. Wash the hood gently by hand with a soft cloth and soapy water.
Protect Fabric Hoods:
Clean the soft top and reapply a manufacturer-recommended water repellent every few months to maintain waterproofing.
Watch for Warning Signs:
Persistent damp smells, wet carpets, or excessive window fogging mean a leak may be developing. Get an inspection early – it’s far cheaper than repairing ongoing water damage!

FAQs
How can I find a car water leak specialist near me?
Finding a true car water leak specialist near you can be tricky – most general garages avoid these complex jobs because convertible leak diagnostics require specialist experience.
At Cayman Autos, we handle the problems others turn away, accurately locating and fixing leaks that standard workshops often miss. While we’re based in Surrey, people travel from across the UK (and even from Europe!) for our expertise. If your convertible is leaking, it’s worth the trip to us to get it fixed properly the first time.
Is a car water leak serious?
Although a water leak might not always start off as serious, it can quickly escalate. What starts as a minor drip can quickly lead to damp carpets, mould, electrical faults, and corrosion to interior components or the vehicle’s structure. Getting the leak professionally diagnosed early prevents expensive repairs later and helps protect your car’s comfort and safety.
How much does it cost to repair a convertible roof leak?
The cost of repair depends on the severity of the leak and whether replacement parts are required. We always aim to provide cost-effective solutions, focusing on repairs rather than replacement. For the most accurate repair price, please get in touch with us.
How often should I check my convertible roof for leaks?
We recommend checking your roof at least twice a year – before and after winter – to catch any early signs of water ingress or other damage. Regular maintenance can extend the life of your convertible top and prevent expensive repairs.
How long does the repair process take?
Most convertible roof repairs can be completed within a day, but it depends on the complexity of the issue. We’ll always give you a clear timeframe once we’ve carried out an inspection.
