Bexleyheath Roof Leak Investigation
Tracing where water is getting into your roof across Bexleyheath, with drones and thermal imaging where they help. Get in touch for a price.
- Damp on a chimney breast
- Stains around a skylight
- Water that shows only in certain storms
Common roof problems in Bexleyheath
Some water in the loft is not rain at all. Moist air from bathrooms and kitchens condenses on the cold underside of the roof, especially where ventilation is poor. Drips from nails and damp underlay are typical signs.
Things that often lead to a survey include:
- Ceiling stains that grow after rain
- Leaks at a dormer or roof window
- Wet patches on loft insulation
- Drips from nail tips in a cold loft
Landlords with a home close to Bexleyheath station may find that a clear finding on where water gets in helps you brief a roofer straight away.

How a roof leak investigation works in Bexleyheath
Older homes have more places for water to get in. Worn lead, tired valley linings and blocked parapet outlets are frequent causes. If your home has a butterfly roof, the central valley gutter is a common culprit. Parapet walls and their gutters are checked from wherever it’s safe. Our report shows what we found, with photos. We survey rooflights and dormers, lead flashings and flat roof details, and people most frequently book us about a leak that comes and goes with the weather and damp walls below an overflowing gutter.
In London, leaks often start somewhere hidden: a butterfly roof’s central valley gutter, a parapet gutter, a chimney flashing or a flat roof over a back addition. For a leak or storm damage in Bexleyheath, those hidden details are where the inspection begins. A hidden gutter that overflows can send water a long way before it shows.
If any part of the leaking roof couldn’t be seen safely, we say so in the report. You’ll know exactly what was inspected and what wasn’t.

What else we do in Bexleyheath
What we do, step by step
We’ll ask a few questions first, like when any problem began and what work has been done before. Then the inspection itself takes an hour or two on an ordinary house, or half a day or so for a commercial building. 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. Mention any building rules, key holders or managing agents when you book.
- We help you choose the package that suits the leak.
- A visit is booked for a weekday, Saturday or Sunday.
- The investigation works from the stain back to the roof.
- Where it is useful and included, we take moisture readings and use thermal imaging.
- You get photos, the likely cause and clear recommendations.
Before the survey
- Check the loft hatch can be reached
- Buyers: confirm access with the estate agent or seller
- Unlock side gates and any roof access doors
Book a survey
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. Otherwise, simply ring 07833 053749 or drop us an email whenever suits you.

Before and after the survey
There’s plenty you can do without going near the roof. What helps most:
- Tell us if there are tanks or pipes in the loft
- Put a bucket under the drip and move valuables
- Move stored items away from the hatch
- Keep a photo record of the damp patch
If there are several possible sources, we list them in order of likelihood. We say which items need prompt attention, so you know what to deal with first.
Do not block the vents at the eaves. Air movement keeps condensation down, and condensation is a common false alarm. Keep insulation clear of the eaves.
For landlords and managing agents
Landlords, agents and building managers in Bexleyheath and across Greater London can book any of our surveys. To discuss a property or a block, phone 07833 053749 or email us.
Businesses and commercial landlords can book us too. Larger roofs take longer, and they’re priced for the size.
What this survey can’t tell you
Every survey has limits, and it is better to know them up front. Keep these in mind:
- A structural engineer’s report
- A promise to find every leak on a single visit
- Defects hidden under coverings or inside walls without opening up
If you are not sure which survey you need, ring 07833 053749 or email us and we will give you a straight answer before you book. What a survey covers and doesn’t.
Roofs we survey in Bexleyheath

What a roof leak investigation looks like in Bexleyheath
In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. If your home in Bexleyheath is one of them, bay roofs, hips and later dormers each have their own details. Knowing the roof type helps narrow down where water may be getting in. Red House, about 0.4 miles south-west, is one of the historic houses in the wider area around Bexleyheath. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and a listed home or one in a conservation area may need consent for changes of material.
Anyone responsible for a site like Upland Primary School will know that on a building that size, finding the source of a drip means looking well beyond the stain. Trees in and around Danson Park shed leaves that can end up in nearby gutters, and an overflowing gutter soon means a wet wall.
Bexleyheath is about 3 miles south-east of Plumstead, in Greater London. We visit Bexleyheath as part of our work across Greater London, for homes and businesses alike. Bexleyheath is one of the places in Greater London we cover. There’s also a page for London.

Around Bexleyheath
Typical jobs here are in homes near Danson Park, The Volunteer pub and Bexleyheath Academy and the streets around them. There is a railway station in Bexleyheath itself: Bexleyheath station. Well-known places in the area include Bexley Hospital (less than half a mile west) and Bexley Museum (1.2 miles south-east). Open spaces near Bexleyheath include Summer Hill and Wansunt Pit.
Different roofs, different checks
Valleys
Debris in a valley slows the water and pushes it sideways. In heavy rain, it can spill under the edges of the slates or tiles.
Chimney stacks
We look at the outside of the stack and the breast inside, not a flue, gas or sweep inspection.
Bexleyheath: your questions answered
Do you carry out roof surveys in Bexleyheath?
We do. The survey and report are the same in Bexleyheath as anywhere else, and visits run on weekdays and weekends.
Does a conservation area affect roof work in Bexleyheath?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
How much does a roof leak investigation cost in Bexleyheath?
Prices start from £150, including VAT. Our three packages are Basic from £150, Standard from £250 and Premium from £400, with VAT included.
How do you tell a leak from condensation?
The two can look alike. Drips from nail tips, damp underlay over a wide area and poor loft ventilation point towards condensation. We check the pattern of damp and the ventilation, then say which is most likely.
Do you look in the roof space?
Where it is relevant to the survey and there is safe access, yes. Please clear anything stored under the hatch, and if the loft can’t be reached safely, the report says so.
Will you fly a drone over my roof?
Where it is applicable and safe, yes. We fly a sub-250g drone and we are a CAA-registered drone operator (Flyer ID and Operator ID). Drone inspection is part of the Drone Roof Survey and the Premium Survey, where applicable.
When does the report arrive?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. Each one is emailed.
