About our electronic leak detection in Flamstead
You get a report showing the location of each breach, with photographs. Your roofer can then repair those points instead of hunting for the leak. We do not estimate repair costs; that’s for your roofer to price. Testing again after repairs can confirm the breaches have been dealt with if the build-up allows. You get a report with photographs. We survey liquid-applied waterproofing, flat roof membranes and single-ply roofs, and people most often book us about waterproofing to test before it’s covered and a flat roof leak that can’t be traced.
Some older homes in villages like Flamstead are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. If you are planning work, check with the council first. Finding out what state the roof is in gives you the facts to plan with. Listed building consent is needed for changes that affect a listed building’s special interest.
Nothing in the report is left vague: where something needs attention, it says so plainly, along with how urgent it is.

What happens on the day
Before we start, let us know why you’ve booked: buying, a leak, storm damage, new work or just wanting to know where things stand. It helps us focus on what matters most to you. The visit usually takes longer on a large roof than a small one, with the construction of the roof playing a part too. Cottages and farmhouses around Flamstead often have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints.
- We start with what you know about the roof and the leak.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
Getting ready for the survey
- Gather any invoices or paperwork from past roof work
- Make a note of anything you’d like us to look at

Advice
Can I check my roof myself?
After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.
Watch the gutters in a downpour, from a window or the ground. Overflowing water can point to a blockage or a sagging run.
Why get it checked now?
A visual inspection can miss tiny holes. Electronic testing can find breaches you can’t see by eye where the roof suits it. For an older or listed building in a place like Flamstead, repairs may need matching materials and consent, so leaving a defect until it’s urgent leaves less time to plan.
The cost of a survey depends on the roof: its size, its height, how many sections it has and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.
What you get with us
- An independent look at the roof
- A sub-250g drone, flown with a CAA Flyer ID and Operator ID
- Insured for professional indemnity and public liability
- Drone and thermal imaging surveys available

Electronic leak detection in Flamstead: local notes
About 4.6 miles south-east lies Childwickbury Manor, a reminder of how long the area around Flamstead has been built on. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
The streets around a church such as Church of St Leonard are often among the oldest in a place, and if your home is one of the older ones nearby, flat-roofed rear additions and dormers added over the years are worth checking. If you let a flat or house near Harpenden station, the flat roof over a let home is worth a look before it becomes a tenant complaint. If you look after a building such as Flamstead Village School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.
