What we look for on each type of roof
Flat roof upstands and outlets
Flat roof water can travel under the covering before it shows. Moisture readings and thermal imaging can help narrow it down where conditions suit.
Valleys
A valley leak can appear well away from the valley inside. From inside the loft space, we follow the water’s route back.
About our roof leak investigation in Horns Green
Most roof leaks start at a joint rather than the middle of a slope. Flashings at chimneys and walls, valleys, gutters, parapets and flat roof upstands and outlets are the usual suspects. Each of these is checked in turn and we follow where the evidence leads. Every chimney, dormer and roof light adds more joints to check. Each one is checked from wherever it is safe to see it. We survey flat roof details, slate and tile slopes and valleys and parapet gutters, and the problems we are asked to look at most are stains around a skylight and leaks below a flat extension roof.
Being in a small place like Horns Green makes no difference to how a leak or storm damage is looked at: we simply plan the journey and access ahead. Tell us where the water shows, when it appears and anything you’ve noticed outside, plus any earlier repairs. If you have photographs of the water coming in, they help as well.
Every survey ends with a written report, with photos, sent by email. It sets out the condition of the leaking roof, any defects and our written recommendations.

For landlords and managing agents
If you own several properties, you can book surveys for several addresses. To discuss a number of properties, phone 07833 053749 or send us an email.
Where a roof is shared: access has to be agreed with whoever owns or manages the building. Tell us about it as you book and we’ll plan the visit with that in mind.
How it works
Every roof is different; as a rough guide, the survey takes an hour or two for most homes, though a hard-to-trace leak can take longer. If you have questions on the day, just ask. Rural addresses near Horns Green can be hard to find from a postcode alone, so a few directions are welcome. The visit itself is the same as anywhere else.
- You let us know where the water shows and when it appears.
- The visit starts indoors, at the stain and in the loft.
- We check the likely entry points outside, such as flashings, valleys, chimneys and gutters.
- 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.
How to prepare
- Jot down any questions you want answered
- If the roof is shared, arrange access with whoever manages the building
- Make sure pets are kept safely away

- Your postcode, so we can check access and travel
- The kind of building and roof involved

Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. For any other survey, just call 07833 053749 or drop us an email when you are ready.
Should I look at the roof myself first?
A DIY look is useful, but it is not a survey. From ground level, valleys, flashings and the backs of chimneys are frequently out of sight, and those are details a survey looks at closely.
Keep a simple record: dates of leaks, photos from ground level and any work done on the roof. Send it with your enquiry and it will help the survey.

Roof leak investigations in Horns Green: local notes
Down House, about 2.1 miles north-west, is one of the historic houses in the wider area around Horns Green. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material. 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. Where water gets in depends a good deal on what the roof is made of and how it is detailed.
For an older house near a landmark such as Church of St Peter and St Paul, the leak may come from a chimney, a valley or tired lead rather than the covering itself. If you look after a building such as Charles Darwin School, a leak through a large roof is often found some distance from where the water shows inside. Landlords with a home close to Knockholt station may find that a clear finding on where water gets in helps you brief a roofer straight away.

Questions from Horns Green
Do you cover smaller places like Horns Green?
Yes, Horns Green is on our map. Villages and rural addresses get the same survey as a town house.
How do I find out if my home in Horns Green 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.
How much does a roof leak investigation cost in Horns Green?
Prices start from £150, including VAT. Our three packages are Basic from £150, Standard from £250 and Premium from £400, inc. VAT.
How do you tell a leak from condensation?
Condensation can look very like a leak. Widespread damp on the underside of the roof in cold weather, with blocked vents, suggests condensation. We check the pattern, take moisture readings and tell you which is more likely.
What will the report tell me?
You get our findings in writing, part by part, with photos, and ends with what we recommend. The most urgent items are made clear.
Does the report include photos?
Yes. The report includes photographs of what we found, so you can see each point for yourself.
Can every leak be traced?
Not always, and we will be honest about that. Water can travel a long way, and some leaks only show in particular storms. Where the source is not certain, we list the likely routes in order.
