Roof leak investigation in Thong: what you get
On older houses, leaks often start at lead work and hidden gutters. 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 looked at from wherever it is safe. Our report shows what we found, with photos. If you’ve noticed wet patches on loft insulation and damp patches next to the stack, a survey will tell you what’s going on, on chimney stacks, slate and tile slopes and the roof space alike.
In a village or hamlet like Thong, older cottages and farmhouses often have roofs that have been patched over many years. A new leak may be fresh damage or the latest sign of long-term wear, and the difference matters, particularly to an insurer. We look at what can be seen safely and set out what we find. Older walls and timbers hold water for a long time, so it’s worth finding the cause soon.
The report records the leaking roof as we found it on the day. It’s useful straight away, and a good reference for later.

Thong: your questions answered
Does being near the coast affect roofs in Thong?
Frequently, yes. Thong is within about 4 miles of the sea, and coastal roofs tend to see faster wear on metal parts and more wind lifting loose pieces.
How do I find out if my home in Thong is listed?
Start with Historic England’s list for listing and your council for conservation areas. It’s worth checking before planning roof work, as both can affect what’s allowed.
Will you fix the leak as part of this?
The investigation is about finding the cause. The repair isn’t part of it. You get a report with photos showing where the water is getting in and what needs attention, which whoever carries out the work can follow.
I live in a flat. Can you survey the roof?
Yes, once access has been agreed. Roofs over flats are frequently shared, so we need permission from the building owner or managing agent. We inspect only the parts we are allowed to reach.
Do you climb onto every roof?
Only when it’s safe. Safety comes first, and fragile or steep roofs can’t always be walked on. We use safe viewpoints, the roof space and a drone where applicable, and the report records anything we couldn’t see.
Does someone need to be in?
If the survey includes the loft or the inside of the building, someone needs to let us in. We will talk about access when booking.
Can you survey at the weekend?
Visits run seven days a week in the daytime. Just say which days work for you.
What you can safely check yourself
The one thing to avoid is getting up close. Roofs are fragile and slippery. That is where a survey comes in, using safe viewpoints and a drone where applicable.
If you have a loft with safe access, take a look inside. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
How it works
On the day, we begin with a quick chat about the roof and anything that is worrying you. After that, we check everything we can see safely. Most surveys take roughly 1–2 hours, more where the leak is intermittent or the roof is large. In a hamlet or village like Thong, a postcode doesn’t always lead to the right gate, so a few directions are welcome. After that, the survey runs as it would anywhere.
- We help you choose the package that suits the leak.
- We agree a date, including weekends.
- 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
- Jot down any questions you want answered
- Show us where any leaks or stains appear
- If the roof is shared, arrange access with whoever manages the building

Related advice
Before and after the survey
Here are a few things we’d tell any owner:
- Take dated photos of the leak
- Let us know what has already been tried
- Stay off ladders and the roof
- Have an electrician check any wet fittings
Any roofer you ask to quote can work from the report. The photos show the defects and where they are, so the repair is aimed at the cause.
Keep the loft space ventilated. Air movement keeps condensation down, and condensation is a common false alarm. Check insulation does not block airflow at the eaves.
Thong roofs and the weather
Thong is within about 4 miles of the coast, so there’s more wind and more salt in the air than further inland. Strong wind lifts anything already loose, and driving rain gets in wherever it can, while salt slowly corrodes metal fixings and flashings. With Cobham College about 1.5 miles south, Thong 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, and a listed home or one in a conservation area may need consent for changes of material.
For landlords with property near Sole Street station, tracing a leak quickly matters when a tenant is living with it. If you live in an older home near Church of St Peter and St Paul, lead flashings, valleys and old chimneys are typical places for water to get in. Anyone responsible for a site like Riverview Infant School will know that a leak through a large roof is often found some distance from where the water shows inside.
Thong is about 2 miles south-east of Gravesend, in Kent. Thong is one of many places we visit across Kent. Across Kent, we cover Thong and the places around it. You can also see our page for Maidstone.

For landlords and managing agents
Shared roofs need a little more planning: we need access agreed with whoever owns or manages the building. Tell us about it when you book and we’ll plan the survey around it.
If the property is let, the agent or a tenant can let us in, at a time agreed in advance. Surveys run on any day of the week, which helps when tenants work during the week.
How the survey changes by roof type
Chimney stacks
We check the outside of the stack and the breast inside, not a flue, gas or sweep inspection.
Valleys
Valleys collect water from two roof slopes. Split lead, cracked linings or slipped tiles let water in.
