About our electronic leak detection in Hatfield Hyde
Our ELD report shows where each breach was found with photos. It tells your roofer exactly where to repair instead of hunting for the leak. We don’t estimate repair costs, so your roofer prices the work. Testing again after repairs can confirm the breaches have been dealt with, where the roof still suits the method. You get a photo-illustrated written report. If you’ve noticed punctures from foot traffic or tools and leaking laps in the waterproofing, we can find out what’s behind it, whatever the roof.
Around a smaller place like Hatfield Hyde, flat roofs typically cover extensions, garages and dormers. They’re small, but a leak over a kitchen extension can do a lot of harm. What it’s covered in, and how well it was laid, decides what it needs. From an upstairs window, look for standing water, splits and edges coming away.
If any part of the flat roof membrane couldn’t be seen safely, we say so in the report. You’ll know exactly what was inspected and what wasn’t, and what we’d suggest next.

What electronic leak detection looks like in Hatfield Hyde
Welwyn Garden City, which Hatfield Hyde is part of, was laid out as a garden city in the early twentieth century. Its first houses are now over a hundred years old, with later estates and newer homes around them. On the oldest homes, nails, battens and underlay may have reached the end of their life even where the tiles look sound, and parts of a garden city may be in a conservation area, so check with the council before re-roofing. The wider area around Hatfield Hyde has a long history of building, with Hatfield House about 1.7 miles south-west. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first.
If your home is one of the older ones in the streets near St Mary Magdalene Church, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. Anyone responsible for a site like Creswick Primary & Nursery School will know that schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks. For businesses in and around places such as Howard Centre, the flat roofs over shops and commercial units are worth checking before a leak, not after.

FAQs for Hatfield Hyde
Does a conservation area affect roof work in Hatfield Hyde?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Do you cover Hatfield Hyde?
We do. Every survey there gets the same written report with photographs, and visits run on weekdays and weekends.
Do you carry professional indemnity insurance?
Every survey is covered by professional indemnity and public liability insurance, and we can provide details if a managing agent needs them.
Does ELD work under paving or planting?
Sometimes. The layers on top and the build-up below decide it and parts may need to be lifted. We talk this through first.
What happens after the survey?
We email you the written report with photographs and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
Will you check the loft?
Yes, where the survey calls for it and there’s safe access. We look for staining, damp, daylight and signs of movement, as far as the space allows.
Can you survey in bad weather?
A survey can usually go ahead in light rain. Strong wind or a downpour can stop drone flights and make roof access unsafe, so if conditions aren’t right we’ll arrange another day with you.
Tips from our surveys
A survey works best with a little help from you, before and after. Some tips:
- Act on new leaks promptly
- Consider ELD before paving or planting goes on
- Record dates and spots where water appears
- Use boards when working on the roof
If we think the leak isn’t coming through the membrane, the report says so, so other causes can be checked.
Make sure contractors protect the waterproofing when they work up there. Have the roof looked at after other work.
Rented homes, blocks and businesses
If the property is let, the agent or a tenant can let us in. We survey on weekdays and at weekends, which can make access easier.
Landlords, agents and building managers in Hatfield Hyde and across Hertfordshire can book any of our surveys. To discuss a property or a block, call 07833 053749 or use the contact form.
What happens if roof problems are left?
Leaks left running can wet the insulation and deck. Finding the breach sooner limits that. In an older home around Hatfield Hyde, water from a roof defect can get into timber and plaster, and that is a much bigger job than the original defect.
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. The price is confirmed before booking.

What else we do in Hatfield Hyde
Honest limits
Without opening up the roof, some things stay hidden, so a survey has limits:
- Sections we cannot safely access
- How wet the insulation is
- Leaks from walls, copings or rooflights
If in doubt, phone 07833 053749 or use the contact form and we will suggest the right survey. What a survey covers and does not.
What this survey covers
- Liquid-applied waterproofing
- Single-ply roofs
- Commercial flat roofs
- Green roofs
- Roof terraces and balconies
- Flat roof membranes
How the survey works
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, with the construction of the roof playing a part too. In a smaller place like Hatfield Hyde, as anywhere, the forecast plays a part: the parts that need calm, dry weather are planned around it.
- We start by finding out what the roof is made of and where it leaks.
- We confirm whether the roof is suitable for electronic testing.
- We pick the low-voltage or high-voltage method that suits the roof.
- Testing runs across the roof to locate breaches in the membrane.
- The breaches are recorded with photographs in a report for your roofer.
How to prepare
- Have any questions written down, so nothing gets missed
- Tell us about parking before the day
- Have keys ready for side gates, garages or roof access doors
