Leaks and storm damage in Sepham Heath
The wider area around Sepham Heath has a long history of building, with Lullingstone Castle about 3.1 miles north-east. Older homes in the wider area frequently have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material. 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. Kent’s older buildings take in oast houses and timber-framed Wealden hall houses as well. The covering and its details give the first clues when tracing where water is coming from.
For site and facilities teams at buildings such as Halstead Community Primary School, tracing a leak on a big roof starts with where the water appears and works back. If you live in an older home near Otford Lane Mission Church, old mortar, worn lead and slipped slates are the usual suspects when water gets in. If you live near a park such as Polhill Bank, or anywhere with mature trees, autumn leaves can block gutters and valleys, so outlets and downpipes are worth watching.

Roof leak investigation in Sepham Heath
Water is good at hiding where it gets in. It can run along a rafter, a batten or the underlay before it drips, so the stain on your ceiling is seldom right under the hole. We follow it back towards where it starts, one likely route at a time. Patching the spot above the stain often misses the real cause. Tracing the route first means any work can be aimed at the right place. If you’ve noticed drips from nail tips in a cold loft and water that shows only in certain storms, a survey will tell you what’s going on, whatever the roof.
Roofs in small places like Sepham Heath often stand in the open, where storms hit ridges, verges and chimneys hardest. Once water gets into older walls, it takes a long time to dry, which makes finding the cause quickly worthwhile. A record with photos is useful if you need to show the damage to anyone else.
If any part of the leaking roof couldn’t be seen safely, we say so in the report. You will know exactly what was inspected and what wasn’t, and what we’d suggest next.

How the survey works
It helps to start with what’s prompted the survey: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. The visit normally takes an hour or two at a typical home, with bigger or more complicated roofs taking longer. In a hamlet or village like Sepham Heath, a postcode does not always lead to the right gate, so a few directions, or a note of a nearby landmark, help us arrive on time. The visit itself is the same as anywhere else.
- You get in touch with details of the leak and any photos.
- Inside, we check the damp area and the loft space above it.
- Outside, we check every likely route in.
- Where it helps, we take moisture readings and use thermal imaging.
- You receive a written report with photos showing the likely source and what needs attention.
Getting ready for the survey
- Tell us where we can park nearby
- Agree roof access with the managing agent if it’s shared
- Make sure pets are kept safely away

Older and listed buildings around Sepham Heath may need consent and matching materials for repairs, so a defect found early gives time to plan the work properly.

How the survey changes by roof type
Slate and tile slopes
A gap in the coverings exposes the underlay. Older felt may hold for a while, but it tears with age.
Valleys
Valleys collect water from two roof slopes. Split lead, cracked linings or slipped tiles let water in.
Questions from Sepham Heath
Is Sepham Heath within the area you cover?
Yes, Sepham Heath is on our map. A small place gets exactly the same survey as a big one, with the route planned beforehand.
Do you cover Sepham Heath?
We do. Every survey there gets the same written report with photographs.
Will you definitely find the leak?
Not always, and we will be honest about that. Some leaks hide well, especially those that need wind-driven rain. If we cannot be sure, the report ranks the possible sources.
What’s the best way to book?
Just call 07833 053749 or send us an email. After a few questions, we confirm the price and fix a day.
Do you use thermal imaging to find leaks?
Thermal imaging is used where it is useful, and it is included in our Premium Survey. It shows temperature differences, not water itself, so we confirm its findings with moisture readings.
Does the investigation include the repair?
A leak investigation finds and reports the likely source. The repair isn’t part of it. The report shows where the water gets in and what should be done, which whoever carries out the work can follow.
How much does a roof leak investigation cost in Sepham Heath?
Roof leak investigation starts from £150, including VAT. You will know the price for your survey before booking, and it depends on the roof’s size, access and the package you choose. For a price, phone 07833 053749 or use the contact form.

Landlords, agents and building managers in Sepham Heath and across Kent can book any of our surveys. For a price for a let property or a block, call 07833 053749 or use the contact form.

- Structural calculations (that’s a structural engineer’s job)
- Faults hidden behind ceilings or boarding
- Putting the leak right
If in doubt, ring 07833 053749 or drop us an email and we’ll recommend the right survey before you book. What a survey covers and doesn’t.

Tips that help
There’s plenty you can do without going near the roof. Here’s what helps most:
- Catch drips in a bucket and protect the floor
- Mention earlier attempts to fix the leak
- Don’t climb onto the roof to look
- Make sure the loft is accessible
The report gives whoever carries out the work a clear starting point. They’ll see exactly where the problem is, so the repair is aimed at the cause.
Look at the roof from the ground after strong winds. Slipped slates, lifted ridge tiles and debris on the ground are signs to act on. Small faults dealt with quickly rarely become leaks.
