About our roof leak investigation in Bromley
On a flat roof, water can travel a long way under the covering. Common causes are splits and blisters, tired upstands and outlets that do not drain. Ponding water makes any weakness worse. We check the roof surface and the ceiling below to narrow it down. Flat roofs over extensions, garages and dormers are frequent sources of leaks. Felt often lasts around 15 to 20 years, so age is part of the picture. We are often asked to look into damp walls below an overflowing gutter and water through the ceiling under a flat roof, on lead flashings, chimney stacks and the roof space.
In converted houses and blocks across London, water from a roof can run a long way before it shows on a ceiling, sometimes in a different flat from the one below the defect. That makes the source hard to pin down, and finding it matters for whoever has to deal with it. In Bromley, we inspect what we can reach safely and are given access to. It is useful to know when the water appears and in what weather.
You can share the report with anyone who needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

What a roof leak investigation looks like in Bromley
Many homes in inner London are Victorian and Edwardian terraces, frequently with 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 Bromley 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. With Sutton House about 2.2 miles north-west, Bromley sits in an area with a long building history. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof.
Trees in and around Bob's Park shed leaves that can end up in nearby gutters, so outlets and downpipes are worth watching. If you own a rental within reach of West Ham station, a tenant living with a leak needs the cause found, not just the stain painted over.
Bromley is about 2 miles east of Whitechapel, in Greater London. Anywhere in Bromley, we can carry out roof leak investigations at your property. We cover towns and villages across Greater London, large and small.
All of E3, E14 and E15 is covered for roof leak investigations, from the main roads to the quietest streets. If you need a roof leak investigation at a property on Bow Road, Bruce Road and Edgar Road or a nearby road, we can survey it. Nearby, we also carry out roof leak investigations in Three Mills (1 mile north-east), Mill Meads (1 mile north-east), Bow Common (1 mile south-west), Mile End (1 mile west) and Bow (1 mile north-west). We also work in nearby towns such as London (4 miles south-west), City of Westminster (6 miles west), Marylebone (6 miles west), Kensington (8 miles west), St Pancras (4 miles west) and Shoreditch (3 miles west).
Local landmarks in Bromley
Around Bromley, our work takes us to homes and buildings near Bob's Park, East London Arts & Music and Bow School and the streets around them. For rail, the closest station is West Ham station, about 1 mile east of the centre. Nearby you’ll also find Tower of London (2.8 miles south-west) and Stratford Centre (1.4 miles north-east). The countryside around Bromley includes Old Ford Island and Tower Hill.
Before and after the survey
Getting the most from a roof leak investigation starts before we arrive and carries on afterwards. Some tips:
- Do not climb onto the roof to look
- Make sure the loft is accessible
- Don’t touch fittings that water is reaching
- Write down the wind direction and rain when it leaks
If condensation is the cause, we explain it, with recommendations on ventilation. It saves chasing a leak that isn’t there.
Look at the roof from ground level after strong winds. Slipped slates, lifted ridge tiles and debris on the ground are signs to act on. Prompt repairs stop gaps turning into leaks.
How the survey works
The aim of the visit is simple: to see as much of the leaking roof as can safely be seen and record it clearly. Notes and photos go into the written report. The visit usually takes roughly 1–2 hours, more where the leak is intermittent or the roof is large. In a London area like Bromley, the main things to sort out are parking and access: tell us about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. On the day, the roof is looked at from ground level, from windows, from inside the loft space and from the roof where it’s safe.
- You get in touch with details of the leak and any photos.
- The visit starts indoors, at the stain and in the loft.
- We check the likely entry points outside, like flashings, valleys, chimneys and gutters.
- Where it helps, we take moisture readings and use thermal imaging.
- We email a report with photographs, the likely entry point and recommendations.
Before we arrive
- Keep pets inside or away from the areas we’re looking at
- Check we can get to the back of the property
- Let us know where we can park nearby
Getting a price
Booking is simple: just phone 07833 053749 or use the contact form, let us know about the property and we’ll suggest the right survey. The price is agreed up front.

When to book a survey in Bromley
When a slate slips or a tile cracks, the underlay takes the water. Ageing felt underlay eventually tears and lets water through, while some very old roofs have nothing under the coverings. Corroded nails, known as ‘nail fatigue’, are a frequent cause on slate roofs.
Here are some of the things we see often:
- Leaks at a dormer or roof window
- Water through the ceiling under a flat roof
- Water that shows only in certain storms
- Staining around the chimney inside
For site and facilities teams at buildings such as St Agnes RC Primary School, on a building that size, finding the source of a drip means looking well beyond the stain.
Before booking anyone
- Their report turnaround times
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- How much experience they have with roofs like yours
- Are they insured for the work?
How the survey changes by roof type
Chimney stacks
Damp on a chimney breast inside often starts at the top of the stack. Unused flues with open pots can let rain straight in.
Lead flashings
Some roofs have mortar where you’d expect lead. Fillets crack and pull away over time, and water runs down behind them.
What a survey costs
To price your survey, we look at:
- Chimneys, valleys, parapets and other details
- The type of building, from a house to a block or an office
- The number of roofs, including extensions and garages
- Basic, Standard or Premium
There are three survey packages: Basic from £150, Standard from £250 and Premium from £400, with VAT included. The price for your roof depends on its size, access and what you’d like to know.
Booking your survey
We’ll usually ask about:
- Whether there is a loft hatch, a shared roof or tricky access
- Your postcode, so we can check access and travel
- Photos of the roof, taken safely from ground level or a window
- When you need the report by
Most bookings start with a short call: call 07833 053749 or email us, and we will ask about the building and what you need. You’ll have a price before anything is arranged.
Questions from Bromley
Does a conservation area affect roof work in Bromley?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it is worth checking before planning any.
Do you cover Bromley?
Yes. We cover the whole of London and South East England, and Bromley is part of that. Just call 07833 053749 or send us an email and let us know about the property.
Do I need to be at home?
That depends on the survey. For inside areas and the roof space, someone has to give us access, while outside access can be discussed when booking.
How much does a roof leak investigation cost in Bromley?
Our price is from £150, including VAT. You’ll know the price for the job before booking, based on the roof’s size, access and package. For a price, phone 07833 053749 or drop us an email.
What insurance do you have?
Professional indemnity and public liability insurance cover our surveys. Ask if you need details for a managing agent or building owner.
How long have you been surveying roofs?
We have more than 20 years’ experience and have completed over 5,000 surveys across London and South East England.
Will you fix the leak as part of this?
This service finds and reports the cause, not to carry out the repair. With the report, a roofer knows exactly where to look.

Why it’s worth a survey now in Bromley
Leaks tend to get worse, not better. Each storm can open a gap a little more. Tracing it now lets you plan the work rather than react to it. Blocked gutters and hoppers on London houses overflow and soak brickwork, which can lead to damp inside. A blocked outlet ignored for a winter or two can mean damp walls inside.
Thermal imaging and drone inspection (where it applies) come with the Premium Survey, from £400 with VAT included. We can help you choose the package that fits what you need to know.
