Roof leak investigation in Farnham Common
On a flat roof, water can travel a long way under the covering. Common causes are splits and blisters, tired upstands and outlets that do not drain. Ponding water makes any weakness worse. 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. If you are worried about water through the ceiling under a flat roof and water dripping from rafters or underlay, a survey will tell you what’s going on.
For a small place like Farnham Common, the inspection is the same as anywhere: the journey and access are just planned beforehand. It helps to know where the water appears, in what weather, and what you’ve seen outside, plus any earlier repairs. If you have photographs of the water coming in, they help as well.
We write the report in plain English, so you don’t need to be a roofer to follow it. Each point is backed by a photo where possible, and recommendations are put by urgency where it matters.

What we look for on each type of roof
Chimney stacks
Chimneys let water in through pointing, flaunching, flashings and open pots. Each is checked from every safe viewpoint, and look for damp on the breast inside.
Flat roof upstands and outlets
Flat roof water can travel under the covering before it shows. Moisture readings and thermal imaging can help narrow it down where conditions suit.
Farnham Common questions
Do you cover Farnham Common?
Yes, Farnham Common is one of the places we work. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
Does a conservation area affect roof work in Farnham Common?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you are planning to re-roof in a different material.
Do you survey roofs on blocks of flats?
Yes, once whoever controls the roof agrees access. We look at the parts we are given access to, and the report makes that clear.
Is thermal imaging part of a leak investigation?
Thermal imaging is used where it is useful, and it is included in our Premium Survey. It shows temperature differences, not water itself, so anything it suggests is checked with moisture readings.
What does the report include?
Written findings 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 applicable and structural analysis.
What does a roof survey cost?
Prices start from £150, including VAT. We confirm the price for the job before you book. For a price, call 07833 053749 or drop us an email.
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 are a CAA-registered drone operator.

How the survey works
We’ll ask a few questions first, like when any problem began and what work has been done before. The inspection then takes about one to two hours at most homes, while a commercial roof takes nearer three to four hours. Somewhere like Farnham Common needs a little journey planning: let us know about lanes, gates and parking. The roof is looked at from the ground, from windows, from the loft where there is safe access and from the roof where it’s safe.
- You tell us where the water appears, when, and what the weather was doing.
- Inside, we check the stain and the ceiling around it.
- From the loft 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.
- We email a written report showing where the water most likely gets in.
Before we arrive
- Buyers: confirm access with the estate agent or seller
- Check we can get to the back of the property
- Leave a clear route to the loft

Advice
What affects the cost of roof leak investigations
What a survey costs depends on the time and equipment it needs. The main factors are:
- Which survey package you book
- Extra roofs, like extensions, dormers or garages
- Whether it is a home or a commercial building
- Chimneys, valleys, parapets and other details
Prices start from £150, including VAT. The final price depends on the size and height of the roof, how it can be seen safely and which survey you book.
What we need to know
When you call or email, these details help:
- The type of building and roof, such as pitched or flat
- Dates you’re working to, like exchange
- Any photos you have, taken from ground level or a window
- What made you get in touch
Buyers should book once an offer has been accepted, so there’s time to use the report before exchange. For any other survey, just call 07833 053749 or email us when you’re ready.
Farnham Common roofs and the weather
Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates, and flat-roofed additions turn up almost everywhere. Knowing the roof type helps narrow down where water may be getting in. The wider area around Farnham Common has a long history of building, with Cliveden about 3.3 miles west. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area.
For site and facilities teams at buildings such as Farnham Common Junior School, water through a big roof can travel a long way before it drips, so the search covers more than the obvious spot. If your home is one of the older ones in the streets near St John the Evangelist, the leak may come from a chimney, a valley or tired lead rather than the covering itself.

When to book a survey in Farnham Common
A roof valley collects the rain from two slopes. Worn lead, cracked linings or a build-up of leaves and moss can push water under the slates or tiles. Leaks from valleys often show up some distance away inside.
A survey makes sense if you’ve noticed:
- Ceiling stains that grow after rain
- Damp ceilings under a flat roof
- Staining where a gutter or parapet meets the wall
- A leak that comes and goes with the weather
If you own a rental within reach of Burnham station, a tenant living with a leak needs the cause found, not just the stain painted over.
Before you book anyone
- How they plan to inspect the roof safely
- Will they check the loft as well as the outside?
- Whether you get a written report with photos
- What the survey will not cover
Why get it checked now?
Water damage grows the longer it is left. Damp spreads into rafters, ceilings and insulation. Tracing it now means less to put right later. In a place like Farnham Common, a barn or garage roof left to fail puts whatever is inside at risk. It’s worth including them in a survey before a winter does the damage.
Prices quoted always include VAT, and the report isn’t charged as an extra. Prices start from £150, including VAT. Size, height and access decide where your roof falls.

Tips from our surveys
These tips come from what we see on roofs every week:
- Leave roof access to professionals
- Take dated photos of the leak
- Clear the loft hatch so we can get in
- Check whether pipes or tanks run near the stain
If the leak turns out to be condensation, the report says so, and suggest how the roof space could be better ventilated. That avoids roof work that wouldn’t help.
Have flashings and flat roofs looked at every few years. They’re where most leaks start, and catching wear early keeps water out.
