Questions from Eel Pie Island
How do I find out if my home in Eel Pie Island is listed?
Start with Historic England’s list for listing and your council for conservation areas. Either can affect what roof work is allowed, so it is worth checking before planning any.
Will parking be an issue for a roof survey in Eel Pie Island?
It can be, so it helps to tell us about permits, visitor bays or off-street space as you book. The visit is then planned around what’s available.
Are you insured?
We hold professional indemnity and public liability insurance, for every survey we carry out.
Which days do you carry out surveys?
We survey seven days a week: weekdays, Saturdays and Sundays. Just let us know the days that suit you.
Is it the same as a RICS Level 2 or Level 3 survey?
No. We’re experienced roof surveyors, and our survey covers the roof rather than the whole building. If you need a full building survey, you will need a RICS survey as well.
Can you give me structural calculations?
No. We’re experienced roof surveyors, and visible signs such as sagging are noted, but calculations and an engineer’s opinion are outside what we do. The report will say if you need an engineer.
Will I get photos?
Yes. The report includes photos of what we found.
How a roof leak investigation works in Eel Pie Island
Water is good at hiding where it gets in. Water often travels along timbers or underlay before it finds a way down, so a ceiling stain is rarely directly below the cause. We follow it back towards where it starts. Patching the spot above the stain often misses the real cause. Finding the route first lets the repair go where it is needed. If you’re worried about condensation that looks like a leak and wet patches high on an inside wall, a survey will tell you what’s going on, on lead flashings, valleys and parapet gutters and the roof space alike.
Many London homes are well over a century old and their roofs have been patched more than once. Telling wear from a one-off event matters, because insurers typically exclude wear and tear. A careful look in Eel Pie Island tells the two apart where the evidence allows. A written record with photographs helps you explain what was found to whoever deals with it next.
The report is yours to share with whoever needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

What affects the cost of roof leak investigations
Every roof is different, so prices are confirmed before you book. This is what makes a difference:
- Whether it’s a home or a commercial building
- Whether thermal imaging or a drone is needed
- The number of roofs, including extensions and garages
- Roof area
All our prices include VAT. Prices start from £150, including VAT. We confirm the exact price before booking.
Helping us price your survey
A little information up front helps. Please include:
- Any stains, drips or damp patches you’ve seen indoors
- The style of property, from a terrace to a block
- Your timetable, such as an exchange date
- The address and postcode of the property
For a price for roof leak investigations in Eel Pie Island, call 07833 053749 or email us. A few details about the property and the roof help us give you an accurate price.
What we can’t see
Our survey isn’t a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. Other limits to bear in mind:
- A promise to find every leak on a single visit
- Water from pipes, tanks or heating systems
- What’s under the covering or behind the plaster
If you are not sure which survey you need, call 07833 053749 or use the contact form and we will give you a straight answer. What a survey covers and does not.
What we look at
- Chimney stacks
- Lead flashings
- Flat roof details
- The roof space
- Rooflights and dormers
- Valleys and parapet gutters
- Slate and tile slopes
DIY checks: what’s safe
Watch the gutters in a downpour, from a window or the ground. Overflowing water can point to a blockage or a sagging run.
A lot can be seen from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please don’t climb up for a closer look.

What we are asked to look at in Eel Pie Island
A gutter that overflows can soak a wall and mark the ceiling inside. Hidden gutters behind parapets cause the most trouble, since a blocked outlet sends water over the lining and into the building.
Common reasons to book include:
- Leaks that appear only in driving rain
- Damp underlay across a wide area
- Staining around the chimney inside
- Leaks at a dormer or roof window
If you look after a shop, office or commercial unit, for instance near Treaty Centre, a leak can close part of a shop or office, so finding the cause quickly matters.
Before booking anyone
- Whether the loft space is looked at, where there is one
- What happens after the report arrives
- What experience they bring
- Which viewpoints they use to see the roof
Before and after the survey
Most of what helps is simple and safe from the ground. A few suggestions:
- Photograph the stain each time it appears
- Mention any plumbing above the damp area
- Note the weather when the leak shows
- Don’t touch fittings that water is reaching
Where we find more than one possible route, we say which is most likely and why. Recommendations are prioritised by urgency where relevant, so you know what to deal with first.
Look at the roof from the ground after strong winds. Slipped slates, lifted ridge tiles and debris on the ground are signs to act on. Small faults dealt with quickly rarely become leaks.
The survey, step by step
Photos are taken throughout the visit, so the report shows exactly what we saw. Close-ups come from the safest viewpoint available, including by drone where it is applicable and the weather allows. Most surveys take about one to two hours for most homes, though a hard-to-trace leak can take longer. In Eel Pie Island, visits are available on weekdays and at weekends. It helps if you can point us to a visitor permit or a nearby bay. Upstairs rooms at the back are useful too, as they often give the best view of a rear addition.
- You tell us where the water appears, when, and what the weather was doing.
- We examine the damp area and the rooms near it.
- From the roof space, we trace the water’s route where there is safe access.
- We inspect the likely entry points outside, from the ground, windows and the roof where safe.
- You receive a report with the likely source, photos and recommendations.
Getting ready for the survey
- Check we can get to the back of the property
- Show us where any leaks or stains appear
- Clear the way to the loft hatch

Most bookings start with a short call: ring 07833 053749 or use the contact form and we will ask a few questions about the roof. You will have a price before anything is arranged.

Eel Pie Island roofs and the weather
In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Where water gets in depends a good deal on what the roof is made of and how it is detailed. Historic houses like Richmond House, about 0.2 miles west, show how far back building in the area around Eel Pie Island goes. Older roofs in the wider area can hide decades of patch repairs, so the detail matters.
For site and facilities teams at buildings like St Mary's Church of England Primary School, a leak through a large roof is frequently found some distance from where the water shows inside. Trees in and around Marble Hill Park shed leaves that can end up in nearby gutters.
