What a roof leak investigation looks like in Coldharbour
About 2.2 miles north lies Ightham Mote, a reminder of how long the area around Coldharbour has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs. Handmade clay tiles, including Kent peg tiles hung on pegs through two holes, are typical of older Kent buildings. The county’s older buildings also include oast houses and timber-framed Wealden hall houses. Different coverings let water in at different points, which shapes where the search starts.
Anyone responsible for a site like St Margaret Clitherow Catholic Primary School will know that on a building that size, finding the source of a drip means looking well beyond the stain. If you let a flat or house near Hildenborough station, a tenant living with a leak needs the cause found, not just the stain painted over.

How a roof leak investigation works in Coldharbour
Not every drip is a leak. Condensation in a cold, poorly ventilated loft can drip from nails and timbers, leaving marks that look just like rainwater. Telling the two apart matters, because they need very different work. We check the pattern of damp, the weather and the ventilation before reaching a view. If you are worried about drips in the loft during heavy rain and ceiling stains that grow after rain, a survey will tell you what’s going on.
Many homes in small places like Coldharbour face open ground, where storms hit ridges, verges and chimneys hardest. Once water gets into older walls, it takes a long time to dry, so it pays to find the cause quickly. A record with photos is useful if you need to show the damage to anyone else.
Where we can’t see part of the leaking roof, the report says so. You’ll know exactly what was inspected and what wasn’t, and what we’d suggest next.

How we price roof leak investigations
When we price a survey, we consider:
- The use of thermal imaging or a drone
- How big the roof is
- Features like valleys, chimneys, dormers and parapets
- Extra roofs, like extensions, dormers or garages
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how safely it can be seen. Our price is from £150, including VAT.
Booking your survey
Getting the details right at the start saves time. It’s useful to include:
- Whether there is a loft hatch, a shared roof or tricky access
- The style of property, from a terrace to a block
- Where water is showing inside, if it is
- When you need the report by
Surveys can be booked for weekdays, Saturdays or Sundays. To find a date that works for you, call 07833 053749 or email us.
Landlords, agents and block managers in Coldharbour
Where a roof is shared: access has to be agreed with whoever owns or manages the building. Mention it when you contact us and we will plan the survey around it.
Letting agents can arrange access with tenants, at a time agreed ahead of time. Surveys run on any day of the week, which can make access easier.
What we’re asked to look at in Coldharbour
Flat roofs fail with age and wear. Felt frequently lasts around 15 to 20 years, and splits, blisters and lifting laps let water in. Upstands and outlets are common weak points.
Here are some of the things we see often:
- Damp underlay across a wide area
- Damp on a chimney breast
- Wet patches high on an inside wall
- Brown rings on upstairs ceilings
For an older house near a landmark like Parish Church of St John, leaks on older roofs often start at lead flashings, valleys or around old chimney stacks.
What to check before booking
- Will they check the loft as well as the outside?
- Whether any drone flown is registered with the CAA
- Whether the price includes VAT
- Will the report include photos?
Roof by roof
Slate and tile slopes
Ridge and hip tiles can loosen as their mortar cracks. Water then gets in along the top of the roof.
Lead flashings
Lead flashings seal the joints at chimneys, walls and dormers. We check for lead that has lifted, split or slipped.
Practical tips
Getting the most from a roof leak investigation starts before we arrive and carries on afterwards. Tips:
- Don’t climb onto the roof to look
- Put a bucket under the drip and move valuables
- Photograph the stain each time it appears
- Record whether it leaks in every downpour or only some
Where we find more than one possible route, we say which is most likely and why. Recommendations are prioritised by urgency where relevant.
Keep the roof space ventilated. Good airflow reduces condensation, and condensation is a common false alarm. Keep insulation clear of the eaves.

How it works
You don’t need to do much on the day. Show us any stains, drips or problem areas you know about, and we’ll get on with the inspection. The survey itself takes about one to two hours, more where the leak is intermittent or the roof is large. For a village or hamlet like Coldharbour, the journey is planned beforehand: let us know about lanes, gates and parking. On the day, we inspect whatever is safely visible, inside and out.
- You let us know where the water appears, when, and what the weather was doing.
- We examine the damp area and the rooms near it.
- In the loft, we follow any signs of water back towards the roof.
- Outside, we check flashings, valleys, chimneys, gutters and flat roof details from every safe viewpoint.
- You receive a report with the likely source, photos and recommendations.
Getting ready for the survey
- For flats, check roof access has been agreed
- Buyers: confirm access with the estate agent or seller
- Unlock side gates and any roof access doors

Advice
FAQs for Coldharbour
Do you cover Coldharbour?
Yes, Coldharbour is within the area we cover. We work right across London and the South East. You can call 07833 053749 or send us an email with the address and some details, and we will talk through which survey suits.
How do I find out if my home in Coldharbour is listed?
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.
Is it the same as a RICS Level 2 or Level 3 survey?
No. We are experienced roof surveyors, and our survey covers the roof rather than the whole building. For the rest of the building, a RICS home survey is a separate job.
How long have you been surveying roofs?
We have been surveying roofs for over 20 years and have carried out more than 5,000 surveys.
How long does a roof leak investigation take?
It normally takes an hour or two for a house, and longer for a large or complex roof. The report follows within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium.
Will you fly a drone over my roof?
Where it helps and the rules allow, yes. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and the airspace and weather are checked before every flight.
What happens after the survey?
The report arrives 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.
