Roof leak investigations for homes and businesses in Longfield Hill
Water is good at hiding where it gets in. Water often travels along timbers or underlay before it finds a way down, so the stain on your ceiling is seldom right under the hole. We follow it back towards where it starts. Patching the spot above the stain frequently misses the real cause. Tracing the route first means any work can be aimed at the right place. We survey chimney stacks, lead flashings and slate and tile slopes, and people most frequently book us about damp patches next to the stack and water coming in around a roof light or dormer.
Being in a small place like Longfield Hill makes no difference to how a leak or storm damage is looked at: we simply plan the journey and access ahead. Let us know where the water shows, when it appears and anything you’ve noticed outside, along with any repairs done before. Photographs of the stain and of the roof from outside are helpful too.
The Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

What a roof leak investigation doesn’t cover
Without opening up the roof, some things stay hidden, and that sets some limits:
- Leaks from plumbing, tanks or pipework rather than the roof
- Whether rotten timbers meet design loads
- Defects hidden under coverings or inside walls without opening up

Longfield Hill: your questions answered
Is my home in Longfield Hill listed or in a conservation area?
Start with Historic England’s list for listing and your council for conservation areas. It is worth checking before planning roof work, as both can affect what’s allowed.
Is the coastal weather around Longfield Hill hard on roofs?
Generally, yes: wind and salt air take more of a toll near the sea. Ridges, verges, flashings and fixings are where it usually shows.
Why is the stain in a different place from the leak?
Water rarely drops straight down. It runs along rafters, battens or underlay before it drips, so the entry point is often well away from the mark. We follow the route back instead of guessing.
Is it a leak or condensation?
Condensation can look very like a leak. Drips from nail tips, damp underlay over a wide area and poor loft ventilation point towards condensation. We check the pattern, take moisture readings and tell you which is more likely.
Do I have to be there for the survey?
It depends on what we need to see. Inside the building and in the loft, we need someone to let us in.
Are you insured?
Our surveys are covered by professional indemnity and public liability insurance. If you need details for a managing agent or a building owner, just ask.
How experienced are you?
We have more than 20 years’ experience and have carried out more than 5,000 surveys.
For landlords and managing agents
If you own several properties, you can book surveys for several addresses. To discuss a number of properties, call 07833 053749 or drop us an email.
We also survey roofs for businesses and commercial landlords. Bigger roofs take more time.

What else we do in Longfield Hill
What a roof leak investigation looks like in Longfield Hill
The coast is about 5 miles or less from Longfield Hill, and being near the sea means more wind and salt than a roof inland would face. Strong wind lifts anything already loose, and driving rain gets in wherever it can. Across Kent, older roofs are often handmade clay or peg tiles, and tile-hanging on upper walls is a familiar sight. You’ll also find oast houses and timber-framed Wealden hall houses among the county’s older buildings. Each of these roof types has its own typical places for water to get in.
For landlords with property near Meopham station, finding the cause of a leak fast keeps a tenant’s home dry and the work focused. Cobham College, about 2.8 miles east, is one of the historic houses in the wider area around Longfield Hill. Older roofs in the area may have lead flashings, valleys and gutters that have been patched many times.
Longfield Hill is about 3 miles south of Northfleet, in Kent.

Local landmarks in Longfield Hill
In Longfield Hill, that means homes and buildings near Rectory Meadow and Longfield Academy and the streets around them.

Not far away are Sawyers Lake.
What happens if roof problems are left?
Lingering damp encourages mould on ceilings and walls. Once mould takes hold, it’s harder to clear. Finding the leak comes first. Where a roof is exposed, as many are in small places like Longfield Hill, driving rain gets into any weakness, and older walls, once damp, take a long time to dry.
Every price we give includes VAT, and the report isn’t charged as an extra. Prices start from £150, including VAT. Size, height and access decide where your roof falls.

How the survey works
We’ll ask a few questions first, such as when any problem began and what work has been done before. The inspection then takes an hour or two, more where the leak is intermittent or the roof is large. Older roofs in small places like Longfield Hill can have low, tight loft spaces, so it’s useful to know whether there is a loft hatch and how easy it is to reach. We only go where it is safe.
- You let us know where the water shows and when it appears.
- Inside, we check the damp area and the loft space above it.
- We check the likely entry points outside, like flashings, valleys, chimneys and gutters.
- We use moisture detection, and thermal imaging where it’s useful.
- We email a report with photos, the likely entry point and recommendations.
Before we arrive
- Unlock side gates and any roof access doors
- Tell us where we can park nearby
- Keep pets inside or away from the areas we’re looking at

If you’re buying, it helps to book soon after your offer is accepted, so there’s time to use the report before exchange. For any other survey, just call 07833 053749 or use the contact form when you’re ready.
Advice
When to book a survey in Longfield Hill
Flashings are one of the commonest sources of roof leaks. Where a roof meets a chimney, a wall or a dormer, lead or mortar seals the joint. Once that seal cracks or lifts, water gets behind it.
Typical things we’re asked to look at include:
- Ceiling stains that grow after rain
- Leaks at a dormer or roof window
- Leaks below a flat extension roof
- Water dripping from rafters or underlay
Trees in and around Rectory Meadow shed leaves that can end up in nearby gutters, and blocked gutters overflow and soak walls.
Questions to ask before booking
- What the report includes, and whether it has photographs
- What happens after the report arrives
- Their drone registration, if they fly one
- Whether the loft is part of the inspection
