How the survey works
The aim of the visit is simple: to look at the leaking roof as closely as is safe and record what we find. Everything we note and photograph goes into the written report. The visit typically takes about one to two hours for most homes, though a hard-to-trace leak can take longer. From the street, a London terrace typically shows only its front slope or parapet, so a visit in North Cheam moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. If other people live in the building, let us know who can let us into the shared parts.
- You pick a Basic, Standard or Premium Survey.
- We agree a date, including weekends.
- The investigation works from the stain back to the roof.
- Where it is useful and included, we take moisture readings and use thermal imaging.
- You get photos, the likely cause and clear recommendations.
Getting ready for the survey
- Leave a clear route to the loft
- Mention any parking restrictions on your street
- Jot down any questions you want answered

Roof leak investigation in North Cheam: what you get
On a flat roof, water can travel a long way under the covering. Common causes are splits and blisters, tired upstands and outlets that don’t drain. Ponding water makes any weakness worse. We check the roof surface and the ceiling below. Flat roofs over extensions, garages and dormers are frequent sources of leaks. Felt often lasts around 15 to 20 years, so age is part of the picture. If you’ve noticed water coming in around a roof light or dormer and water marks that spread in wet weather, a survey will tell you what’s going on.
Water getting into a London home frequently comes from a detail you can’t see from the street: the valley gutter in a butterfly roof, a parapet gutter, a chimney flashing or the flat roof over a rear extension. For a leak or storm damage in North Cheam, 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.
The written findings come by email, easy to pass on to a roofer, an agent or an insurer. Turnaround is within 48 hours for Basic, 24–48 hours for Standard and same day for Premium.

How the survey changes by roof type
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.
Parapet and box gutters
Hidden gutters run behind parapets or between roofs. When their outlets block, water rises over the lining and runs indoors.
FAQs for North Cheam
Is parking a problem for a survey in North Cheam?
London parking needs a little planning, so let us know about permits, bays or a driveway as you book. The visit is then planned around what’s available.
How do I find out if my home in North Cheam is listed?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Is this an asbestos survey?
No. Our report may flag materials that could contain asbestos, but only a specialist asbestos surveyor can confirm it. It may be present in buildings built or refurbished before 2000.
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.
Does the report include photographs?
Yes. Photos are part of every report, so you can see each point for yourself.
How do I book a survey in North Cheam?
Simply phone 07833 053749 or use the contact form. We will ask a few questions, confirm the price and agree a date.
Do you look in the loft space?
Yes, where the survey calls for it and there is safe access. Inside, we look for damp, staining, gaps and sagging.
What we are asked to look at in North Cheam
A gutter that overflows can soak a wall and mark the ceiling inside. Parapet and box gutters are the worst for this, since a blocked outlet sends water over the lining and into the building.
We’re often asked to look at:
- Damp patches next to the stack
- Leaks at a dormer or roof window
- Leaks that appear only in driving rain
- Water dripping from rafters or underlay
For businesses in and around places such as The Ashley Centre, water through a ceiling can damage stock and close a sales floor, so the source needs finding fast.

North Cheam roofs and the weather
Outer London has a good many Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often 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. The covering and its details give the first clues when tracing where water is coming from. About 1 mile south lies Nonsuch Mansion, a reminder of how long the area around North Cheam has been built on. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material.
For landlords with property near West Sutton station, finding the cause of a leak fast keeps a tenant’s home dry and the work focused. Homes near green spaces like Nonsuch Park can get more leaves in their gutters in autumn, and an overflowing gutter soon means a wet wall.
