Roof leak investigation in Grange Park, Greater London
Roof leak investigations across Grange Park, backed by more than 20 years’ experience. You get a clear report with photos.
- Water dripping from rafters or underlay
- Brown rings on upstairs ceilings
- Water coming in around a roof light or dormer
Should I look at the roof myself first?
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date, which helps when we look at the roof.
A DIY look is useful, but it is not a survey. You will not see flashings, valleys or the backs of chimneys properly from ground level.
About our roof leak investigation in Grange Park
We use moisture detection and thermal imaging where they help. Moisture detection confirms where timbers, plaster or insulation are damp. Thermal imaging shows temperature differences that can point to wet areas, not water itself, so its findings are checked with moisture readings. Thermal imaging is part of the Premium Survey, and moisture detection comes with Standard. Thermal imaging works best after a sunny day, on a dry roof with little wind. We survey lead flashings, flat roof details and chimney stacks, and people most frequently book us about wet patches high on an inside wall and water coming in around a roof light or dormer.
In London, leaks often start somewhere hidden: a butterfly roof’s central valley gutter, a parapet gutter, a chimney flashing or a flat roof over a back addition. For a leak or storm damage in Grange Park, those hidden details are where the inspection begins. Water from a hidden gutter can run along joists and show up a room or two away.
If any part of the leaking roof couldn’t be seen safely, we say so in the report. That way, it is clear what was covered and what wasn’t.

What a roof leak investigation looks like in Grange Park
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Each of these roof types has its own typical places for water to get in. About 2 miles north-east lies Forty Hall, a reminder of how long the area around Grange Park has been built on. 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 St Mary Magdalene, the leak may come from a chimney, a valley or tired lead rather than the covering itself. If you run a business near Edmonton Green Shopping Centre, water through a ceiling can damage stock and close a sales floor, so the source needs finding fast. If you own a rental within reach of Grange Park station, a clear finding on where water gets in helps you brief a roofer straight away.

Surveys for landlords and agents in Grange Park
An agent can book and manage the survey for a landlord, with the report sent to whoever needs it. We agree a time with the tenant beforehand.
We survey roofs for landlords and agents as well as homeowners. A photo-illustrated written report gives you a clear record of the leaking roof.
How the survey works
Expect us to ask a few questions before we start, about the roof’s history, any leaks and past repairs. Then the inspection itself takes between one and two hours for most homes, though a hard-to-trace leak can take longer. In a London conversion, the way into the roof space is often from a communal landing or the top flat. Where that’s the case, access needs agreeing with whoever controls that landing. Everything else is planned around the building, not the postcode.
- You let us know where the water shows and when it appears.
- The visit starts indoors, at the stain and in the loft.
- Outside, we check every likely route in.
- We use moisture detection, and thermal imaging where it is useful.
- You receive a written report with photos showing the likely source and what needs attention.
Before we arrive
- Point out any leaks or damp patches
- Have keys ready for side gates, garages or roof access doors
- Check pets are kept safely away
Booking a survey
Roof leak investigation starts from £150, including VAT. What you pay depends on the roof’s size, access and the package, so call 07833 053749 or email us with the details.

What affects the cost of roof leak investigations
We confirm the price for your roof before you book. This is what makes a difference:
- Whether it is a home or a commercial building
- Extensions, dormers and garages with roofs of their own
- The shape of the roof and its details
- Any need for thermal images or a drone flight
Simple, low roofs take less time to survey than tall or complicated ones, and the package matters as well. We’ll give you the figure before anything is booked.
Helping us price your survey
These details help when you contact us:
- Whether there is a loft hatch, a shared roof or tricky access
- Where water is showing inside, if it is
- Any deadline, like an exchange date
- What’s prompted the survey
If you have photos of the roof, send them over. Pictures from ground level or a window are fine, and please don’t climb up for a closer look. To send them or to book, call 07833 053749 or email us.

Leave it or get it looked at?
Lingering damp encourages mould on ceilings and walls. Once mould takes hold, it’s harder to clear. Finding the leak comes first. In Grange Park, as in much of London, water from a roof defect can reach a neighbour’s home as easily as yours: a blocked parapet gutter or slipped slate can let water into the flat below or the house next door. Finding it early keeps the work smaller.
Every price we give includes VAT. Our price is from £150, including VAT. You’ll know the price for the job before you book.

Your questions about roof leak investigations in Grange Park
Is Grange Park in the area you cover?
Yes. We work right across London and the South East, and Grange Park is part of that. Just phone 07833 053749 or send us an email and let us know about the property.
Can parking be tricky for a visit in Grange Park?
Sometimes, yes. If Grange Park has controlled parking where you are, a visitor permit is the easiest answer, and a driveway is even better.
Can you inspect my roof with a drone?
Where it helps and it is safe, yes. Whether we can fly on the day depends on the weather and the airspace rules. We hold a CAA Flyer ID and Operator ID.
What’s in the report?
A report with photographs, explaining the condition of the leaking roof, any defects and our recommendations, by urgency where it matters. The Standard Survey adds moisture detection and a structural check, and the Premium Survey adds thermal imaging, drone inspection where it applies and structural analysis.
Do you climb onto every roof?
Only where it is safe to do so. We look at everything that can be seen safely: from ground level, from windows and vantage points, from the roof space, from the roof itself where safe and by drone where it applies. Anything we cannot see is noted in the report.
How experienced are you?
We’ve completed more than 5,000 surveys, over more than 20 years.
Can you always find the source?
Not always, and we will be honest about that. Water can travel a long way, and some leaks only show in particular storms. If we cannot be sure, the report ranks the possible sources.
What we look for on each type of roof
Flat roof upstands and outlets
Each flat roof relies on its outlets to drain. A blocked outlet leaves water standing, which tests every joint. Outlets and the area around them are looked at.
Slate and tile slopes
Slipped, cracked or missing slates and tiles let rain onto the underlay. Ageing felt eventually lets water through.
