Whether an EPDM roof can be tested depends on the membrane and build-up. We check before we quote.
Bituminous membranes
Bitumen roofs can often be tested electronically, depending on what’s below.
Electronic leak detection for homes and businesses in Bowmans
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It works with an electrical current which can only get through the membrane at a breach. That lets us locate holes that are too small to see, so your roofer can repair them. The results come in a report with photos. We survey roof terraces and balconies, green roofs and flat roof membranes, and common reasons people get in touch are patched roofs that still leak and stains far from any visible defect.
Flat roofs in smaller places like Bowmans can be more exposed, especially where nothing shelters them, so wind catches loose edges and trims. Felt and bitumen also age in strong sun. The signs are splits, blisters and edges coming away. Standing water that lingers for days after rain is another sign worth watching for.
What you get is a clear record of the flat roof membrane on the day we saw it. That makes it useful now and a handy reference later, for example when you want to check whether anything has changed.

How do I arrange electronic leak detection in Bowmans?
To book, ring 07833 053749 or send us an email and tell us the address and what you’d like to know. We will confirm the price and agree a day with you.
Will you repair the leak?
No. We test the membrane and report. You get the breach locations with photos for your roofer to repair.
Will you walk on the roof?
Only where it’s safe to do so. We look at everything that can safely be seen: from the ground, from windows and vantage points, from the roof space, from the roof itself where safe and by drone where applicable. Anything we can’t see is noted in the report.
Do you use low-voltage or high-voltage testing?
It depends on the membrane and the build-up. Low-voltage testing normally needs a wet surface and high-voltage methods need the membrane dry and exposed.
Can you give me structural calculations?
No. We’re roof surveyors, not structural engineers, and it does not include calculations. If we see signs that need an engineer’s opinion, we’ll recommend one.
DIY checks: what’s safe
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Do not go up yourself.
You can learn a lot from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please don’t climb up for a closer look.
Signs you need electronic leak detection in Bowmans
Flat roof membranes can be punctured by foot traffic, dropped tools or debris. Many are tiny but water still finds them.
Signs worth acting on include:
- Damage from equipment installers
- A flat roof leak that cannot be traced
- Leaks through a covered membrane
- Holes around roof penetrations
If you look after a building such as Wentworth Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
What to check before booking
- What’s outside the scope of the survey
- How long they’ve been surveying roofs
- What the report includes, and whether it has photos
- Are they insured for the work?
What electronic leak detection doesn’t cover
Before booking, it’s worth knowing what a survey will not do:
- Build-ups without a suitable layer below
- Sections we cannot safely access
- Water entering through details rather than the membrane

Flat and commercial roofs around Bowmans
With Hall Place and Gardens about 1.1 miles north-west, Bowmans sits in an area with a long building history. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first. Handmade clay tiles, including Kent peg tiles hung on pegs through two holes, are typical of older Kent buildings. Oast houses and timber-framed Wealden hall houses are part of the county’s older buildings too. Next to the main roofs there is usually a flat roof somewhere, whether on an extension, a garage or a commercial unit.
For businesses in and around places such as Broadway Shopping Centre, outlets and upstands on commercial flat roofs are the places to check before trouble starts. Landlords with a home close to Crayford station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Bowmans is about 2 miles west of Dartford, in Kent. Anywhere in Bowmans, we can carry out electronic leak detection at your property, on a weekday, Saturday or Sunday. Our Kent coverage includes Bowmans. We also survey roofs in London.

Leave it or get it looked at?
Water trapped under a membrane can soak insulation and decking. Finding the breach sooner limits that. Blocked gutters on homes around Bowmans overflow and soak walls. It is easy to sort the cause early and slow to dry a damp wall.
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. You will know the figure before booking.

- PI and public liability insurance

How the survey works
The aim of the visit is simple: to see as much of the flat roof membrane as can be seen safely and record it clearly. Everything we note and photograph goes into the written report. It typically takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. With a bit of garden around a house, as there often is around Bowmans, the roof can be viewed from several angles. Let us know if any side is fenced off or hard to reach. The loft, where there is safe access, completes the picture.
- We start by finding out what the roof is made of and where it leaks.
- We check that the membrane and build-up suit electronic leak detection.
- The method depends on the membrane and what sits above and below it.
- We test the membrane and find where current is passing through it.
- We send a report with photos of each breach so your roofer can repair it.
Before the survey
- Tell us about parking before the day
- Tell us about any leaks, stains or damp patches you know of
- Agree roof access with the managing agent if it’s shared

Every survey is priced before it is booked, so you know the cost up front. Electronic leak detection is quoted for your roof, because the method depends on the roof. For a price for your roof, ring 07833 053749 or drop us an email.
