How electronic leak detection works in Bulstrode
There are different ELD methods. Low-voltage testing is usually done with the surface wet, while high-voltage testing needs a dry, exposed membrane. The right method depends on the membrane and the build-up of the roof, and we will explain our choice. We will say if your roof doesn’t suit either method before any testing starts. We survey liquid-applied waterproofing, green roofs and commercial flat roofs, and the problems we’re asked to look at most are breaches hidden under paving or planting and a flat roof leak that can’t be traced.
In a small place like Bulstrode, a flat roof can stand in the open, so edges, upstands and laps take a beating. Felt roofs, which often last around 15–20 years, typically show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are typically the first part of a flat roof to go.
Every survey ends with a written report, with photographs, sent by email. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

Electronic leak detection in Bulstrode: local notes
In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. About 3 miles south lies Chenies Manor House, a reminder of how long the area around Bulstrode has been built on. Older homes in the wider area frequently have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material.
If you look after a building like Bovingdon Primary Academy, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. The streets around a church such as Church of St Lawrence are often among the oldest in a place, and if your home is one of the older ones nearby, the joins between later flat roofs and the old walls are where problems typically start.

Roof problems in a rented home affect tenants as well as the building. A survey helps you spot issues early and plan the work.
Freeholders and residents’ companies use a roof report to plan and budget.
Common roof problems in Bulstrode
Roofs covered with paving, ballast or planting hide the membrane. Electronic methods can help on some of these roofs though it depends on the layers.
Typical things we are asked to look at include:
- Breaches hidden under paving or planting
- Failed seams and laps
- Holes left by work on the roof
- Repairs that haven’t stopped the leak
If you let a flat or house near Hemel Hempstead station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Choosing a roof surveyor
- Will the report include photos?
- Their insurance cover
- How they plan to inspect the roof safely
- Whether VAT is added on top
Why it’s worth a survey now in Bulstrode
Not every leak is in the membrane. ELD helps rule the membrane in or out, so other causes can be checked. Where a roof is exposed, as many are in small places like Bulstrode, driving rain gets into any weakness, and older walls, once damp, take a long time to dry.

Bulstrode: your questions answered
Is my home in Bulstrode listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
Will you come out to Bulstrode?
We do. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
When does the report arrive?
Each package has its own report time. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. If you have a deadline, such as an exchange date, tell us when you book.
Can you test a green or ballasted roof?
On some roofs, yes. What sits on the membrane affects the method, so we check the build-up first.
Can you inspect my roof with a drone?
Where it helps and it is safe, yes. Flights depend on the weather on the day and airspace rules, including flight restriction zones near airports. We’re a CAA-registered drone operator.
Can you survey at the weekend?
We survey on any day from Monday to Sunday, during the day. Let us know your preferred days as you book.
Will you repair the leak?
No, our part is finding the breaches. Your roofer uses the report to target the repair.
What electronic leak detection doesn’t cover
No survey can tell you everything, and we’d rather be clear about that before you book. Keep these in mind:
- Build-ups without a suitable layer below
- Parts of the roof covered by fixed equipment
- Fixing the holes we find

How the survey works
A survey visit follows a simple order: we listen to what’s been worrying you, inspect the roof from every safe vantage point, take photos as we go and record our findings for the written report. Most visits take more time on a big roof than a small one, with the construction of the roof playing a part too. Somewhere like Bulstrode 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’s safe access and from the roof where it’s safe.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We check that the membrane and build-up suit electronic leak detection.
- The testing method is chosen to suit the membrane and build-up.
- The roof is tested and any breaches are located.
- We send a report with photos of each breach so your roofer can repair it.
Preparing for the visit
- Have any questions written down, so nothing gets missed
- Point out any leaks or damp patches
- Mention any parking restrictions on your street
