Dorchester Electronic Leak Detection
Not sure what state the flat roof membrane is in? We carry out electronic leak detection in Dorchester and across Oxfordshire.
- Failed seams and laps
- Repairs that haven’t stopped the leak
- Punctures from foot traffic or tools
Should I look at the roof myself first?
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry and it will help the survey.
Your own check is a good start, but it isn’t a survey. You will not see flashings, valleys or the backs of chimneys properly from ground level.
Electronic leak detection in Dorchester
Our ELD report shows where each breach was found with photos. It tells your roofer exactly where to repair rather than guessing. We do not estimate repair costs; that is for your roofer to price. A retest after repairs can check the work, where the roof still suits the method. You get a written report with photos. We survey green roofs, commercial flat roofs and roof terraces and balconies, and common reasons people get in touch are repairs that haven’t stopped the leak and leaking laps in the waterproofing.
Somewhere as small as Dorchester, flat roofs tend to be on extensions, garages and converted outbuildings. The checks are the same as anywhere: the covering, the edges, the upstands and where water drains away. The journey and access are planned beforehand. If there are outbuildings or garages with flat roofs, mention them when booking.
Nothing in the report is left vague: if work is needed, the report says so clearly.

What electronic leak detection looks like in Dorchester
Older buildings in west Oxfordshire often have Cotswold stone slate roofs, and some Oxfordshire villages still have thatch. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. Dorchester has a number of hotels within about a mile and a half. If you look after one, a leak through a flat roof can put a room out of use.
For hotels and guest houses around Dorchester, a roof problem found early is far less disruptive than one found by a guest, so it pays to find faults before guests do. If you own a rental within reach of Culham station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
Dorchester is about 4 miles north-east of Didcot, in Oxfordshire.

Common roof problems in Dorchester
Roofs covered with paving, ballast or planting hide the membrane. ELD can work on some covered roofs though it depends on the layers.
Signs worth acting on include:
- Leaks that return after repairs
- New membranes needing a check before handover
- A flat roof leak that cannot be traced
- Damage from equipment installers
The streets around a church such as Dorchester Abbey are often among the oldest in a place, and if yours is one of the older homes nearby, the flat roofs on later extensions tend to wear out long before the main roof.
What to check before booking
- Whether the loft space is looked at, where there is one
- Are they insured for the work?
- How long they’ve been surveying roofs
- When you will get the report
Dorchester questions
Will you come out to Dorchester?
Yes, we do. We cover the whole of London and South East England, and smaller places are part of that. Longer journeys are simply planned beforehand.
Can you look at the flat roof of a hotel or office near Dorchester?
Yes, commercial flat roofs are part of what we cover. Larger commercial roofs are quoted for the building, and roof access is agreed with you ahead of the visit.
Do you use drones?
Where it helps and the rules allow, yes. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and every flight depends on the airspace and the weather.
What does the report include?
It explains what we saw, what it means and what we’d suggest, backed by photos. It also says if any part of the roof couldn’t be seen safely.
What’s the best way to book?
It’s easiest to call 07833 053749 or use the contact form. Give us the address and a few details about the roof, and we will recommend the right survey. We survey on weekdays, Saturdays and Sundays.
How many surveys have you done?
We have completed more than 5,000 surveys, over more than 20 years, and 98% of customers are satisfied.
I live in a flat. Can you survey the roof?
Yes, once whoever controls the roof agrees access. On a shared roof we can only inspect the parts we’re allowed to reach, and the report makes that clear.
Why act early in Dorchester
Opening up a roof to hunt for a leak is disruptive. Electronic testing finds the hole first so your roofer knows where to work. In a place like Dorchester, 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.
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You’ll know the price for the job before booking.

What we do, step by step
Where it is relevant and can be reached safely, the loft space is checked as well as the outside. In the loft, the signs we look for are staining, damp, daylight and sagging, as far as the space allows. The whole visit normally takes longer on a large roof than a small one, with the construction of the roof playing a part too. In a hamlet or village like Dorchester, a postcode doesn’t always lead to the right gate, so a few directions, or a note of a nearby landmark, help us arrive on time. The visit itself is the same as anywhere else.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Before we arrive
- Make a note of anything you’d like us to look at
- Mention any parking restrictions on your street
- Unlock side gates and any roof access doors

Advice
Before and after the survey
A survey works best with a little help from you, before and after. Some tips:
- Have roof specifications to hand
- Clear flat roof outlets regularly
- Test new membranes before covering them
- Don’t leave water getting in
You receive a report showing where each breach was found, with photos. Pass it to your roofer to repair the breach points.
Consider testing a new membrane before it is covered. Finding breaches is simpler at that stage.
