Electronic leak detection in Benslow, Hertfordshire
Electronic leak detection in Benslow from an independent, experienced roof surveyor. Over 5,000 surveys and 20+ years behind us across London and the South East.

What happens if roof problems are left?
Some flat roof leaks come from walls or details. Testing shows whether the membrane is breached, so other causes can be checked. Homes in smaller places like Benslow can face more weather, so a loose ridge or verge soon lets rain in. Wind gets under it and lifts more.
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. The price is confirmed before booking.

Electronic leak detection in Benslow: what you get
Roofs covered with paving, ballast or planting need more thought. The layers on top can limit the methods we can use, and some may need lifting. We will discuss it with you when we quote. Drawings or details of the roof’s layers are useful, as they show what lies beneath the surface. We’ll tell you if the roof cannot be tested. We are often asked to look into repairs that haven’t stopped the leak and new roofs to check before paving or planting, across flat roof membranes, commercial flat roofs and single-ply roofs.
In a smaller place like Benslow, some flat roofs sit in the open, so wind catches loose edges and trims. Felt and bitumen also age in strong sun. Splits, blisters and lifting edges are what to look out for, along with water that sits after rain. A flat roof that still holds water days after rain is also worth a closer look.
The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent, whichever applies.

Tips that help
Getting the most from electronic leak detection starts before we arrive and carries on afterwards. Some tips:
- Find the breach before more patching
- Don’t leave water getting in
- Have roof specifications to hand
- Don’t let outlets block
Where the evidence points to walls, copings or rooflights, we’ll note it, with a suggestion of what to check next.
Consider testing a new membrane before it is covered. It’s easier to find holes before more layers are added.

Yes, we do. We cover the whole of London and South East England, from towns to the smallest villages. Longer journeys are simply planned in advance.
Do you carry out roof surveys in Benslow?
Yes. We survey roofs across London and South East England, and Benslow is part of that. You can ring 07833 053749 or drop us an email with the address and some details.
Do you survey roofs on blocks of flats?
Yes. A shared roof needs access agreed first. Mention it when you get in touch and we will explain what’s needed.
Is it a structural engineer’s report?
No. We note visible signs such as sagging or deflection, but we do not carry out calculations or give an engineer’s opinion. If we think you need an engineer, the report says so.
When does the report arrive?
It depends on the package: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. The report is emailed to you.
What do I do with the report?
You will receive the report by email, and what you do next is up to you: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Does ELD include fixing the breach?
No, the test finds the breaches and your roofer repairs them. The report gives your roofer the locations.
What we do, step by step
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. In total, it takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Being in a smaller place like Benslow doesn’t change how the visit works: we look from ground level, from windows, from the loft and from the roof where it is safe. It helps to show us anything you’ve already noticed.
- We agree the area to be tested.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.
Getting ready for the survey
- Jot down any questions you want answered
- Keep pets out of the way during the survey
- Agree roof access with the managing agent if it is shared
Book a survey
If you are buying, it helps to book soon after your offer is accepted, so there’s time to use the report before exchange. Otherwise, simply call 07833 053749 or email us whenever suits you.

Electronic leak detection around Benslow
Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. Before planning roof work on an older home, find out whether it’s listed or in a conservation area. 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.
