Roof leak investigation in Swanscombe, Kent
Tracing where water is getting into your roof in Swanscombe. We’ve completed more than 5,000 surveys across London and the South East.
- Water marks that spread in wet weather
- Damp underlay across a wide area
- Leaks that appear only in driving rain
Roof leak investigation in Swanscombe
Our job is to find the likely source and tell you. You get a written report with photos showing the likely entry point and the route the water is taking, and recommends what should be done. Whoever does the work then has a clear starting point. We find and report the source, and the repair itself is a separate job. If you’ve noticed ceiling stains that grow after rain and leaks below a flat extension roof, we can find out what’s behind it, whatever the roof.
Houses in smaller places like Swanscombe can stand more in the open, where driving rain gets into any gap at a ridge, verge or flashing. A leak that only appears in certain weather frequently points to an exposed detail. Let us know when it happens when you get in touch. The gutters on the most exposed side can overflow too.
Findings are set out part by part, from the coverings down to the gutters, with a note and a photo for each point. It records what’s sound as well as what isn’t.

Tips that help
Small things make a difference. Our tips:
- Let us know about any past repairs to the roof
- Don’t touch fittings that water is reaching
- Record whether it leaks in every downpour or only some
- Leave roof access to professionals
Where we find more than one possible route, we say which is most likely and why. We say which items need prompt attention.
After a storm, check the roof from the garden and the street. Pieces of slate or tile in the garden mean something has moved. Small faults dealt with quickly rarely become leaks.
What this survey cannot tell you
A survey is a close look at the leaking roof, but it can’t do everything. Its limits include:
- Putting the leak right
- Water from pipes, tanks or heating systems
- A structural engineer’s report
Not sure which survey suits your roof? You can call 07833 053749 or drop us an email and we’ll tell you. What a survey covers and doesn’t.
Roof types and parts we check
- Slate and tile slopes
- Chimney stacks
- Flat roof details
- Valleys and parapet gutters
- Lead flashings
- Rooflights and dormers
- The roof space
Signs you need a roof leak investigation in Swanscombe
A roof valley collects the rain from two slopes. Worn lead, cracked linings or a build-up of leaves and moss can send that water under the coverings. The stain may appear well away from the valley itself.
Here are some of the things we see often:
- Damp patches next to the stack
- Drips in the loft during heavy rain
- Ceiling stains that grow after rain
- Damp underlay across a wide area
Living close to Castle Hill Park is pleasant, but mature trees mean leaves in gutters and valleys each autumn, and an overflowing gutter soon means a wet wall.
What to check before booking
- How they’ll see the roof: from the ground, the loft, the roof or by drone
- What’s outside the scope of the survey
- What experience they bring
- Whether any drone flown is registered with the CAA
Leaks and storm damage in Swanscombe
Swanscombe lies within about 4 miles of the sea, and places near the sea get more salt in the air and more wind than inland. Wind lifts loose slates, tiles and ridge pieces, and driving rain finds any gap they leave, while salt slowly corrodes metal fixings and flashings. Many older homes in Kent have handmade clay tiles, including Kent peg tiles held by pegs through two holes, and tile-hanging on their upper walls. The county’s older buildings also include oast houses and timber-framed Wealden hall houses. Each of these roof types has its own typical places for water to get in.
If you own a rental within reach of Greenhithe for Bluewater station, a tenant living with a leak needs the cause found, not just the stain painted over. If you look after a building such as Knockhall Primary School, water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot.
Swanscombe is about 3 miles east of Dartford, in Kent. Swanscombe is one of many places we visit across Kent, for houses, flats and commercial buildings. We cover towns and villages across Kent, large and small. We also survey roofs in Maidstone.

What we look for on each type of roof
Flat roof upstands and outlets
The upturned edge of a flat roof covering keeps water out at walls. A low or cracked upstand is a common way in.
Chimney stacks
Our chimney check is a visual inspection of the stack, not a flue, gas or sweep inspection.
Rented homes, blocks and businesses
Letting agents often book on a landlord’s behalf, and the report can go to both. We agree a time with the tenant beforehand.
If you own several properties, surveys can be booked for more than one address. To arrange surveys for several addresses, phone 07833 053749 or email us with the addresses.
FAQs for Swanscombe
Is Swanscombe within the area you cover?
Yes, we do. We work right across London and South East England, from towns to the smallest villages. Longer journeys are simply planned ahead of time.
How do I find out if my home in Swanscombe is listed?
We cannot confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material.
Do you use drones?
Where it’s applicable and safe, yes. We fly a sub-250g drone and we’re a CAA-registered drone operator (Flyer ID and Operator ID). Drone inspection is part of the Drone Roof Survey and the Premium Survey, where it applies.
Will you fix the leak as part of this?
This service finds and reports the cause, and the repair is separate. The report gives any roofer a clear brief.
How long does a roof leak investigation take?
On site, it normally takes about one to two hours at most homes, or half a day or so for a commercial building. Report times depend on the package.
Is thermal imaging part of a leak investigation?
Where conditions suit, it can. The best results come after a sunny day, on a dry roof with little wind. Wet insulation holds heat longer than dry, which can show up on the image. Its findings are confirmed with a moisture check.
What do I do with the report?
You will get the report by email, with photos and clear recommendations. The Standard Survey includes a follow-up consultation, and the Premium Survey an in-person consultation, so you can talk the findings through.

What we do, step by step
Once we’ve finished looking, we write up our findings as a report with photographs. As for time on site, most surveys take roughly 1–2 hours for most houses, or half a day or so for a commercial building. A visit to a smaller place like Swanscombe is no different on the day: we look from ground level, from windows, from the loft and from the roof where it is safe. It helps to show us anything you’ve already noticed.
- You tell us where the water shows and when it appears.
- Inside, we check the damp area and the loft space above it.
- Outside, we look at every likely route in.
- Moisture readings and thermal imaging are used where they help.
- You receive a written report with photos showing the likely source and what needs attention.
Getting ready for the survey
- Move anything stored under the loft hatch
- Agree roof access with the managing agent if it is shared
- Let us know about any leaks, stains or damp patches you know of
