Roof leak investigation in Farningham, Kent
Tracing where water is getting into your roof around Farningham, with a written report you can act on. Weekday and weekend visits available.
- Wet patches on loft insulation
- Condensation that looks like a leak
- Leaks at a dormer or roof window
How it works
You don’t need to do much on the day. Point out anything you’ve noticed, like stains, drips or loose pieces, and we’ll take it from there. The survey itself takes an hour or two for most homes, though a hard-to-trace leak can take longer. In a hamlet or village like Farningham, 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. After that, the survey runs as it would anywhere.
- We help you choose the package that suits the leak.
- A visit is booked for a weekday, Saturday or Sunday.
- We inspect inside and out, starting from the stain.
- Moisture detection and thermal imaging are used where your package includes them and they help.
- The report explains the likely entry point and what needs attention.
Before the survey
- Make a note of anything you’d like us to look at
- Note where any stains or damp appear
- Find any records of previous roof work
Getting a price
We confirm the exact price before booking, so you know where you stand. Prices start from £150, including VAT. For a price for your roof, phone 07833 053749 or drop us an email.

Roof leak investigations for homes and businesses in Farningham
Flat roofs leak in their own ways. Common causes are splits and blisters, tired upstands and outlets that do not drain. Standing water puts extra pressure on every weak point. We check the roof surface and the ceiling below to narrow it down. Leaks under flat extension, garage and dormer roofs are common. Felt often lasts around 15 to 20 years, so age is part of the picture. We survey rooflights and dormers, slate and tile slopes and flat roof details, and people most frequently book us about water that shows only in certain storms and damp ceilings under a flat roof.
Roofs in small places like Farningham 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, so it pays to find the cause quickly. A record with photos is useful if you need to show the damage to anyone else.
The report does not just list problems. It explains what we found, why it matters and what we recommend, so you can plan your next steps.

Why act early in Farningham
Leaks tend to get worse, not better. Each storm can open a gap a little more. Tracing it now lets you plan the work rather than react to it. Around Farningham, older homes often have old roof timbers, and water through a failed covering can rot timber if it’s left.

What we look for on each type of roof
Flat roof upstands and outlets
On a flat roof, a leak can show some distance from the split. Moisture readings and thermal imaging can help narrow it down where conditions suit.
Valleys
Valleys collect water from two roof slopes. Worn or split linings and slipped valley tiles let it under the coverings.
Checking the roof from the ground
It helps to keep a record: dates of leaks, photos from ground level and any work done on the roof. Share it with us as you book, as it helps us focus the survey.
Your own check is a good start, but it is not a survey. You won’t see flashings, valleys or the backs of chimneys properly from the ground.
Leaks and storm damage in Farningham
Handmade clay tiles, including Kent peg tiles hung on pegs through two holes, are typical of older Kent buildings. Kent’s older buildings take in oast houses and timber-framed Wealden hall houses as well. Where water gets in depends a good deal on what the roof is made of and how it is detailed. The wider area around Farningham has a long history of building, with Lullingstone Castle about 1.8 miles south-west. Older roofs in the wider area can hide decades of patch repairs, so the detail matters.
For an older house near a landmark such as Church of Saint Peter and Saint Paul, lead flashings, valleys and old chimneys are typical places for water to get in. If you let a flat or house near Eynsford station, a clear finding on where water gets in helps you brief a roofer straight away.

When to book a survey in Farningham
Slipped or missing slates and tiles let rain reach the underlay. Ageing felt underlay eventually tears and lets water through, and very old roofs may have no underlay at all. Corroded nails, known as ‘nail fatigue’, are a frequent cause on slate roofs.
Here are some of the things we see often:
- Drips in the loft during heavy rain
- Brown rings on upstairs ceilings
- Staining around the chimney inside
- Condensation that looks like a leak
If you look after a building like The Anthony Roper Primary School, on a building that size, finding the source of a drip means looking well beyond the stain.

- Faults hidden behind ceilings or boarding
- Leaks from plumbing, tanks or pipework rather than the roof
- Carrying out the fix
