Electronic leak detection in Pegsdon: local notes
If your home is older, it’s worth knowing whether it’s listed or in a conservation area before planning roof work. Changes that affect a listed building’s special interest need listed building consent, and councils can also use Article 4 directions to control changes in conservation areas. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles, and flat-roofed additions turn up almost everywhere. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops.
If your house is among the older ones in the streets near Church of St Faith (Church of England), later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear. If you look after a building such as Hexton Junior Mixed and Infant School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.
Pegsdon is about 4 miles west of Hitchin, in Hertfordshire. From houses to flats and shops in Pegsdon, the roof can be surveyed. Our area takes in places right across Hertfordshire, from the larger towns to small villages. Milton Keynes is in our area too.

Electronic leak detection for homes and businesses in Pegsdon
ELD suits many waterproofing membranes on flat roofs over offices, units, blocks of flats and homes. It helps trace a leak you already have or check a new membrane before handover. We quote for each roof based on its size and build-up. We can test on weekdays and at weekends when conditions allow. Just ask about your roof. We survey flat roof membranes, green roofs and single-ply roofs, and the problems we’re asked to look at most are leaking laps in the waterproofing and patched roofs that still leak.
In a small place like Pegsdon, a flat roof can stand in the open, so edges, upstands and laps take a beating. Older felt roofs, often around 15–20 years in life, show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are typically the first part of a flat roof to go.
You can share the report with anyone who needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

Your questions about electronic leak detection in Pegsdon
Will you come out to Pegsdon?
Yes, smaller places are covered as well as towns. We work right across London and South East England. Let us know about access, parking and anything unusual about getting there as you book.
Is Pegsdon in the area you cover?
Yes, Pegsdon is one of the places we work. Every survey there gets the same written report with photographs, and visits run on weekdays and weekends.
Is my roof suitable for ELD?
It depends on the membrane and the build-up. Let us know what you know about the roof and we’ll check whether ELD will work.
What happens after the survey?
We email you the written report with photos and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
What’s the best way to book?
It is easiest to phone 07833 053749 or use the contact form. Let us know the address and a little about the roof, and we’ll take it from there. Surveys run on weekdays and at weekends.
Will you repair the leak?
No. ELD is testing only. The report shows where each breach is so your roofer can fix them.
Will you fly a drone over my roof?
Yes, where it is applicable. Whether we can fly on the day depends on the weather and the airspace rules. We are a CAA-registered drone operator.
What we look for on each type of roof
Single-ply membranes
Single-ply can be punctured by tools or fixings. ELD can locate them.
Liquid-applied waterproofing
Small holes in liquid waterproofing may leak. Where the roof suits it, testing can find them.
What happens if roof problems are left?
Patching where you think the leak is often misses it. Testing shows where the membrane is actually breached. For an older or listed building in a place like Pegsdon, repairs may need matching materials and consent, so leaving a defect until it’s urgent leaves less time to plan.
Every price we give includes VAT. Electronic leak detection is quoted for your roof, because the method depends on the roof. You will know the price for the job before booking.

Signs you need electronic leak detection in Pegsdon
A breach can be left during installation. ELD on a new roof can show holes before they cause leaks.
Most people get in touch after spotting something like this:
- Gaps at membrane joints
- Leaks at pipes, outlets or fixings
- New membranes needing a check before handover
- Stains far from any visible defect
Landlords with a home close to Hitchin station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Questions to ask before you book
- Do they have a CAA Flyer ID and Operator ID for drone work?
- What experience they bring
- Which parts of the roof they’ll actually see
- Whether you can ask questions once you have the report
What happens on the day
A survey visit follows a simple order: we hear what you’ve seen, look at the roof from every safe viewpoint, take photos as we go and make notes for the report. Most visits take as long as needed for the size of the roof and how it’s built, and we’ll give you a guide when quoting. Around Pegsdon, older homes can have small or awkward roof spaces, so let us know about the loft hatch and any ladder. We only go where it’s safe.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.
How to prepare
- Tell us where we can park nearby
- Have any questions written down, so nothing gets missed
- Gather any invoices or paperwork from past roof work
