DIY checks: what’s safe
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.
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Don’t go up yourself.
Roof leak investigation in Dagenham Green: what you get
Leaks tend to begin where one part of a roof meets another. Common entry points include chimney and wall flashings, valleys, parapet and box gutters, and the upstands and outlets on flat roofs. Each of these is checked in turn and follow the evidence. Every chimney, dormer and roof light adds more joints to check. Each one is checked from wherever it is safe to see it. If you’ve noticed condensation that looks like a leak and water through the ceiling under a flat roof, we can find out what’s behind it, whatever the roof.
In London, leaks frequently start somewhere hidden: a butterfly roof’s central valley gutter, a parapet gutter, a chimney flashing or a flat roof over a back addition. Whether you’re tracing a leak or recording storm damage in Dagenham Green, those are among the first places to look. Water from a hidden gutter can run along joists and show up a room or two away.
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.

How it works
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 between one and two hours for a house, and longer for a large or complex roof. London terraces rarely offer a view of the whole roof from one spot, so in Dagenham Green we work round the house, using the street, the windows, the loft and any safe vantage point behind it. Shared stairs or a basement flat? Let us know who holds the keys.
- We start with what you’ve seen: where the stain is and when it gets worse.
- Inside, we check the damp area and the roof space above it.
- Outside, we check every likely route in.
- Moisture readings and thermal imaging are used where they help.
- Your report sets out where the water is most likely getting in, with photos and recommendations.

How the survey changes by roof type
Chimney stacks
Chimneys let water in through pointing, flaunching, flashings and open pots. We check each one as far as we can safely see.
Flat roof upstands and outlets
On a flat roof, a leak can show some distance from the split. Where conditions allow, moisture readings and thermal imaging help narrow it down.
What affects the cost of roof leak investigations
When we price a survey, we consider:
- Building height and the viewpoints available
- Features like valleys, chimneys, dormers and parapets
- The number of roofs, including extensions and garages
- Whether you choose the Basic, Standard or Premium Survey
Every price we give includes VAT, and the report isn’t charged as an extra. Our price is from £150, including VAT. Size, height and access decide where your roof falls.
Helping us price your survey
Getting the details right at the start saves time. Please include:
- The kind of building and roof involved
- Whether there is a loft hatch, a shared roof or tricky access
- What’s prompted the survey
- Your timetable, such as an exchange date
Booking is simple: just call 07833 053749 or send us an email, let us know about the property and we will recommend the right survey. We confirm the price before anything is booked.
Tips from our surveys
Small things make a difference. Our tips:
- Keep a photo record of the damp patch
- Mention earlier attempts to fix the leak
- Clear the loft hatch so we can get in
- Stay off ladders and the roof
Standard includes a follow-up consultation to talk the findings through, and Premium includes an in-person consultation. You can ask us about anything that isn’t clear.
Have leaves and moss cleared from gutters, valleys and outlets, ideally once the leaves have fallen. Many leaks start with a blocked outlet. Leave the clearing to someone with the right equipment.
Roof leak investigations in Dagenham Green: local notes
Outer London has lots of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, frequently with hipped roofs in clay or concrete tiles. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Knowing the roof type helps narrow down where water may be getting in. Rainham Hall, about 1.9 miles east, is one of the historic houses in the wider area around Dagenham Green. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first.
For landlords with property near Dagenham Dock station, a clear finding on where water gets in helps you brief a roofer straight away. For site and facilities teams at buildings such as Marsh Green Primary School, tracing a leak on a big roof starts with where the water appears and works back.

Questions from Dagenham Green
Do you carry out roof surveys in Dagenham Green?
Yes, Dagenham Green is one of the places we work. The survey and report are the same in Dagenham Green as anywhere else.
Can parking be tricky for a visit in Dagenham Green?
It can be, so it’s useful to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
How many surveys have you done?
More than 5,000 surveys over 20+ years.
Will you fix the leak as part of this?
A leak investigation finds and reports the likely source. The repair itself is a separate job. The report shows where the water gets in and what should be done.
Is there anything I need to do before the visit?
Clear the loft hatch so we can get into the loft space. Have any photos of the leak ready, plus details of past repairs. In the meantime, catch the water and keep it clear of lights and sockets.
Can thermal imaging help find my roof leak?
Where conditions suit, it can. It works best after a sunny day, with a dry roof surface and little wind. Damp areas can hold heat differently from dry ones. Its findings are confirmed with a moisture check.
What does a roof survey cost?
Roof leak investigation starts from £150, including VAT. Our three packages are Basic from £150, Standard from £250 and Premium from £400, inc. VAT.
What we’re asked to look at in Dagenham Green
Slipped or missing slates and tiles let rain reach the underlay. Old bitumen felt may cope for a while, but it tears and sags with age, while some very old roofs have nothing under the coverings. Corroded nails, known as ‘nail fatigue’, are a frequent cause on slate roofs.
People normally book a survey after spotting one of these:
- Damp on a chimney breast
- Damp ceilings under a flat roof
- Water dripping from rafters or underlay
- Stains around a skylight
If you live near a park such as Parsloes Park, or anywhere with mature trees, autumn leaves can block gutters and valleys.
Questions to ask before you book
- What insurance they carry
- How long they’ve been surveying roofs
- What the survey won’t cover
