Roof leak investigations for homes and businesses in Bankside
Some ‘leaks’ aren’t leaks at all. In a badly ventilated roof space, condensation can form under the roof and drip, leaving marks that look just like rainwater. Knowing which it is means the right fix can be done, since the cure for one will not solve the other. We check the pattern of damp, the weather and the ventilation before reaching a view. We survey lead flashings, rooflights and dormers and valleys and parapet gutters, and common reasons people get in touch are damp patches next to the stack and brown rings on upstairs ceilings.
Many London homes are well over a century old and their roofs have been patched more than once, so a new leak can be the latest sign of wear rather than a single event. Telling wear from a one-off event matters, because insurers typically exclude wear and tear. That’s as true in Bankside as anywhere in London. Photos and a written account give you something specific to show an insurer, a landlord or a roofer.
We keep jargon out of it: where something needs attention, it says so plainly, along with how urgent it is.

Why it’s worth a survey now in Bankside
Wet insulation doesn’t insulate well. A slow leak can soak it for months before a stain appears. The sooner the cause is found, the less needs replacing. Work on a London roof is rarely simple to arrange, with parking, neighbours and access all to think about. That is a good reason to find problems early, while there’s time to plan, rather than in a rush after a leak.
Prices start from £150, inc. VAT, for a Basic Survey. The Standard Survey starts from £250 and the Premium Survey from £400, both inc. VAT. You will know the price for the job before booking.

How we price roof leak investigations
All our prices include VAT. The things that change the price are:
- If the survey needs thermal imaging or a drone
- Extra roofs, like extensions, dormers or garages
- How tall the building is and how easy the roof is to see
- The package you choose: Basic, Standard or Premium
Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. You’ll know the figure before booking.
Helping us price your survey
There’s no need for technical words. Just let us know:
- When you need the report by
- Your postcode, so we can check access and travel
- Photos of the roof, taken safely from the ground or a window
- The style of property, from a terrace to a block
Every survey is priced before it is booked, so you know the cost up front. Roof leak investigation starts from £150, including VAT. To book, ring 07833 053749 or send us an email.
Tips that help
Getting the most from a roof leak investigation starts before we arrive and carries on afterwards. Some tips:
- Don’t climb onto the roof to look
- Photograph the stain each time it appears
- Have an electrician check any wet fittings
- Clear the loft hatch so we can get in
Once the work is done, hold on to the report. If the leak returns, it is a useful record of what was found, which makes the next step quicker.
Don’t block the vents at the eaves. Air movement keeps condensation down, which is frequently mistaken for a leak. Keep insulation clear of the eaves.
How the survey works
Time on site depends on the size and shape of the roof, but as a rough guide the survey takes an hour or two at most homes, and about three to four hours for a commercial roof. You’re welcome to ask questions while we are there. Many London properties are flats or terraces with no side access, so the back of the roof is frequently seen from upstairs windows, from inside or, where a flight is allowed, from the air. If the building has a managing agent or access rules, let us know when you book.
- We start with what you’ve seen: where the stain is and when it gets worse.
- Inside, we check the damp area and the roof space above it.
- Outside, we check every likely route in.
- We use moisture detection, and thermal imaging where it’s useful.
- We email a report with photographs, the likely entry point and recommendations.
How to prepare
- Keep pets out of the way during the survey
- Have any questions written down, so nothing gets missed
- Have keys ready for side gates, garages or roof access doors

Common questions in Bankside
Is Bankside in the area you cover?
Yes. We work right across London and the South East, and Bankside is part of that. You can ring 07833 053749 or use the contact form with the address and some details, and we’ll talk through which survey suits.
How do I find out if my home in Bankside is listed?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Does the report include photos?
Yes, every report has them. Each finding is shown in a picture where possible.
Why isn’t the leak directly above the stain?
Rain that gets in will run along whatever it lands on. On a flat roof it can travel under the covering before it finds a way through the ceiling. Tracing that path is the heart of a leak investigation.
Do you carry professional indemnity insurance?
We hold professional indemnity and public liability insurance.
Can you tell me if my roof has asbestos?
No. Asbestos surveys and sampling aren’t something we do. Where a material might contain it, such as old cement sheets on a building from before 2000, the report flags it.
How do you tell a leak from condensation?
It’s a common question. Leaks tend to follow wet weather and show in one place, while condensation is often spread out and worse in cold weather. We tell you which it is most likely to be.
Different roofs, different checks
Parapet and box gutters
Hidden gutters run behind parapets or between roofs. A blocked outlet sends water over the lining and into the building.
Chimney stacks
Damp on a chimney breast inside often starts at the top of the stack. Open, unused pots let rain fall down the flue.
Roof leak investigations in Bankside: local notes
Inner London’s Victorian and Edwardian terraces often have Welsh slate roofs. From the street you may see only a parapet, with a butterfly roof and a valley gutter behind it draining to the back. If your home in Bankside is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. Knowing the roof type helps narrow down where water may be getting in. The wider area around Bankside has a long history of building, with Mansion House about 0.6 miles north-east. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area.
For site and facilities teams at buildings such as London Nautical School, water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot. If you live near a park such as Bernie Spain Gardens, or anywhere with mature trees, autumn leaves can block gutters and valleys, so outlets and downpipes are worth watching. For businesses in and around places such as Gabriel's Wharf, a quick answer on where water is coming in keeps a business running.
