Wind, rain and roofs in Cobham
About 1.2 miles north lies The Homewood, a reminder of how long the area around Cobham has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs. Many older homes in Surrey have handmade clay tiles and tile-hung upper walls. Horsham stone slab roofs survive on some old buildings in Surrey. Knowing the roof type helps narrow down where water may be getting in.
Trees in and around West End Common shed leaves that can end up in nearby gutters, so outlets and downpipes are worth watching. Landlords with a home close to Cobham & Stoke Dabernon station may find that tracing a leak quickly matters when a tenant is living with it.

Roof leak investigation in Cobham
On a flat roof, water can travel a long way under the covering. Splits, blisters, failed laps, worn upstands and blocked outlets are common causes. Standing water puts extra pressure on every weak point. We look at the roof surface and the ceiling below to narrow it down. 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. We survey flat roof details, lead flashings and slate and tile slopes, and common reasons people get in touch are wet patches high on an inside wall and leaks below a flat extension roof.
Around Cobham, chimneys on older homes are a common source of leaks, through worn flaunching, failed pointing or lifted flashings. Damp on a chimney breast isn’t always rain from above, which is why it is worth tracing properly. The stack, its flashings and the loft space beside it are all worth checking.
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.

What this survey cannot tell you
Without opening up the roof, some things stay hidden, so a survey has limits:
- Plumbing leaks that look like roof leaks
- Defects hidden under coverings or inside walls without opening up
- A promise to find every leak on a single visit

Cobham questions
Do you carry out roof surveys in Cobham?
Yes, Cobham is within the area we cover. We work right across London and South East England. You can ring 07833 053749 or send us an email with the address and a few details, and we’ll talk through which survey suits.
Is my home in Cobham listed or in a conservation area?
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.
Will you fix the leak as part of this?
The investigation is about finding the cause. The repair is not part of it. The report shows where the water gets in and what should be done, which whoever carries out the work can follow.
Is it a leak or condensation?
The two can look alike. Widespread damp on the underside of the roof in cold weather, with blocked vents, suggests condensation. We check the pattern of damp and the ventilation, then say which is most likely.
How long does a roof leak investigation take?
Allow roughly 1–2 hours for most homes, though a hard-to-trace leak can take longer. We will confirm what to expect when we arrange the visit.
Why is not the leak directly above the stain?
Because water travels. It runs along rafters, battens or underlay before it drips, so the entry point is frequently well away from the mark. We follow the route back instead of guessing.
Is there anything I need to do ahead of the visit?
Keep a note of when it leaks. Move stored items away from the loft hatch. If water is near any fittings, have an electrician check them.
For landlords and managing agents
Surveys can also be booked by buyers’ agents acting for a client. The report is emailed, so it can go straight to your client, photos included.
Any of our surveys can be booked by landlords, agents and building managers in Cobham. For a price for a let property or a block, phone 07833 053749 or email us.
When to book a survey in Cobham
Chimneys can let water in by several routes. Eroded pointing, cracked flaunching, failed flashings and open pots can all be responsible. It can show up on the chimney breast, nearby ceilings or in the loft space.
Problems we come across often include:
- Ceiling stains that grow after rain
- Damp on a chimney breast
- Leaks below a flat extension roof
- Leaks that appear only in driving rain
If yours is one of the older homes in the streets near Church of St Andrew, water on an older roof tends to find its way in at the lead, the valleys or the chimney.
Before booking any roof surveyor
- Whether you can ask questions once you have the report
- Whether the price includes VAT
- What’s outside the scope of the survey
- Their report turnaround times
Can I check my roof myself?
During heavy rain, look at the gutters from the ground or a window. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
A DIY look is useful, but it isn’t a survey. From ground level, valleys, flashings and the backs of chimneys are frequently out of sight.
How it works
You do not need to do much on the day. Point out anything you’ve noticed, like stains, drips or loose pieces, and we’ll get on with the inspection. A typical survey takes roughly 1–2 hours on an ordinary house, while a commercial roof takes nearer three to four hours. Parking around Cobham is usually easier than in a town centre, but mention lanes, gates or long drives. On bungalows and lower roofs, much can be seen from ground level, with the loft showing the underside, while taller roofs may need other vantage points or the drone where it applies.
- 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’s 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.
Before we arrive
- Point out any leaks or damp patches
- Move anything stored under the loft hatch
- If it isn’t your property yet, arrange access through the agent
