Roof leak investigation in Thundersley, Essex
Know where you stand with the leaking roof before you decide what to do next. We carry out roof leak investigations in Thundersley, with photographs and a clear written report.
- Leaks at a dormer or roof window
- Leaks below a flat extension roof
- Staining around the chimney inside
The survey, step by step
There isn’t much for you to do on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we’ll get on with the inspection. The survey itself takes roughly 1–2 hours, more where the leak is intermittent or the roof is large. Parking in a town like Thundersley is typically simple, but tell us if there’s a driveway or any restrictions. We check the roof from ground level and from windows, then from the loft where there’s safe access.
- We start with what you’ve seen: where the stain is and when it gets worse.
- The visit starts indoors, at the stain and in the loft.
- Outside, we check every likely route in.
- Where it helps, we take moisture readings and use thermal imaging.
- We email a report with photographs, the likely entry point and recommendations.
Before we arrive
- If the roof is shared, arrange access with whoever manages the building
- If you’re buying, let the agent know when we are coming
- Check we can get to the back of the property
Booking a survey
A quick phone call is usually the easiest start: call 07833 053749 or email us, and we will ask about the building and what you need. You’ll have a price before anything is arranged.
Advice
About our roof leak investigation in Thundersley
Leaks tend to begin where one part of a roof meets another. Flashings at chimneys and walls, valleys, gutters, parapets and flat roof upstands and outlets are the usual suspects. We check each likely route and we follow where the evidence leads. Every chimney, dormer and roof light adds more joints to check. We check all of them, from every safe viewpoint. We survey rooflights and dormers, the roof space and lead flashings, and the problems we are asked to look at most are damp patches next to the stack and stains around a skylight.
Around a town like Thundersley, leaks come from older and newer roofs alike. Older roofs suffer slipped slates, worn mortar and tired lead, while later houses can leak at valleys, verges and flat-roofed additions. Knowing the cause tells you what to do next. It also tells you whether the problem is old wear or something more recent.
What you get is a clear record of the leaking roof on the day we saw it. That makes it useful now and a handy reference later, such as when you want to compare after future work.

Questions from Thundersley
Is Thundersley in the area you cover?
Yes, Thundersley is within the area we cover. We cover the whole of London and South East England. Just phone 07833 053749 or drop us an email and tell us about the property, and we will talk through which survey suits.
Do roofs near the sea, like those around Thundersley, take more of a battering?
Near the coast, roofs face more wind and more salt than further inland. Salt corrodes metal fixings and flashings, and wind lifts loose slates, tiles and ridge pieces.
Which days do you carry out surveys?
Surveys can be booked for any day of the week: Monday to Friday, Saturdays and Sundays. Just let us know the days that suit you.
Do you survey roofs on blocks of flats?
Yes. A shared roof needs access agreed first. Mention it when you contact us and we will explain what’s needed.
Do you carry professional indemnity insurance?
Our cover is professional indemnity plus public liability, and details are available on request.
Can you give me structural calculations?
No. Our survey isn’t a structural engineer’s report, and it does not include calculations. We will recommend an engineer if we see signs that call for one.
Can you inspect my roof with a drone?
Where it helps and it’s safe, yes. Flights depend on the weather on the day and airspace rules, and we check for restrictions near airports before flying. We are a CAA-registered drone operator.

How the survey changes by roof type
Valleys
Debris in a valley slows the water and pushes it sideways. During a downpour, water can back up under the coverings.
Slate and tile slopes
Slipped, cracked or missing slates and tiles let rain onto the underlay. Ageing felt eventually lets water through.
Do you need a roof leak investigation in Thundersley?
A roof valley collects the rain from two slopes. Worn lead, cracked linings or a build-up of leaves and moss can push water under the slates or tiles. Leaks from valleys frequently show up some distance away inside.
Things that often lead to a survey include:
- Drips in the loft during heavy rain
- Leaks at a dormer or roof window
- Damp underlay across a wide area
- Damp on a chimney breast
The streets around a church like Church of St Peter are often among the oldest in a place, and if your house is among the older ones nearby, old mortar, worn lead and slipped slates are the usual suspects when water gets in.

- How long they’ve been surveying roofs
- Will the report include photos?
When you need someone else
Our survey isn’t a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- An intermittent leak that shows no trace on the day
- Structural calculations (that’s a structural engineer’s job)
- Putting the leak right

Roof leak investigations in Thundersley: local notes
Thundersley lies within about 4 miles of the sea, and being near the sea means more wind and salt than a roof inland would face. Wind lifts loose slates, tiles and ridge pieces, and driving rain finds any gap they leave. In Essex, older buildings are often clay-tiled, many with weatherboarding, with post-war and more recent estates making up much of the newer housing. Different coverings let water in at different points, which shapes where the search starts.
If you let a flat or house near Rayleigh station, a tenant living with a leak needs the cause found, not just the stain painted over. If you look after a building like Thundersley Primary School, a leak through a large roof is often found some distance from where the water shows inside.

Tips that help
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Move stored items away from the hatch
- Write down the wind direction and rain when it leaks
- Don’t climb onto the roof to look
- Keep water away from lights and sockets
Any roofer you ask to quote can work from the report. The photos show the defects and where they are, rather than at the stain.
Have flashings and flat roofs looked at every few years. They’re where most leaks start, and wear is easier to deal with before water gets in.
For landlords and managing agents
Where a roof is shared: we need access agreed with the building owner or managing agent. Let us know about it when booking and we’ll plan the visit with that in mind.
We survey roofs for letting agents and landlords as well as householders. The report gives you a dated record of the leaking roof, with photos.
