Electronic leak detection for homes and businesses in Boxmoor
You get a report showing the location of each breach with photos. Your roofer can then repair those points rather than guessing. We don’t estimate repair costs; that is for your roofer to price. Testing again after repairs can confirm the breaches have been dealt with, where the roof still suits the method. Results come in a written report with photos. If you’ve noticed leaks showing away from the breach and water coming in under a flat roof, a survey will tell you what’s going on, on liquid-applied waterproofing, single-ply roofs and roof terraces and balconies alike.
Around a smaller place like Boxmoor, flat roofs normally cover extensions, garages and dormers. Even a small flat roof can let plenty of water into the room below. What it’s covered in, and how well it was laid, decides what it needs, from felt and asphalt to EPDM rubber and GRP. Ponding, splits and lifting edges are the signs to look for from a window.
Nothing in the report is left vague: where something needs attention, it says so plainly, along with how urgent it is.

The survey, step by step
We check the roof from outside and, where it’s relevant and there’s safe access, from inside the roof space too. Inside, we look for staining, damp, gaps and signs of movement. All in, the survey usually takes as long as needed for the roof’s area and construction, which we’ll explain when we quote. Some parts of a survey depend on the weather, so a visit to Boxmoor is booked with the forecast in mind: drone flights and thermal imaging need the right conditions, while a look from ground level and the loft can go ahead in most weather.
- 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.
- 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
- Agree roof access with the managing agent if it’s shared
- Make a note of anything you’d like us to look at
- Buyers: confirm access with the estate agent or seller

Advice
Practical tips
Over many surveys, some simple habits stand out as worth the effort:
- Do not let outlets block
- Act on new leaks promptly
- Check new waterproofing before handover
- Find the breach before more patching
Questions about the results are welcome. We’ll explain what was found and what it means.
Ask trades working on the roof to protect the membrane when they work up there. Have the roof looked at after other work.
Roof by roof
EPDM rubber roofs
EPDM is a long-lasting flat roof membrane, but punctures and seam failures still happen.
Green and ballasted roofs
Parts of the covering may have to come up. We discuss this before quoting.
Rented homes, blocks and businesses
Surveys can also be booked by buyers’ agents acting for a client. Reports are emailed, so they’re easy to pass on.
Roof problems in a rented home affect tenants as well as the building. A survey helps you spot issues early and plan the work around your tenants.
FAQs for Boxmoor
Does a conservation area affect roof work in Boxmoor?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Should a flat-roofed garage or porch in Boxmoor be checked too?
Usually, yes: tell us about it when booking so the visit can include it. Many homes in new towns like Hemel Hempstead have flat-roofed garages and porches, and felt roofs often last around 15–20 years.
How long have you been surveying roofs?
We’ve completed more than 5,000 surveys, over more than 20 years, and 98% of customers are satisfied.
Do you carry out surveys on Saturdays and Sundays?
We carry out surveys on weekdays and at weekends. To arrange a date, phone 07833 053749 or send us an email.
What’s in the report?
It explains what we saw, what it means and what we’d suggest, with photographs throughout. It also says if any part of the roof couldn’t be seen safely, so you know exactly what was covered.
Will you repair the leak?
No, the test finds the breaches and your roofer repairs them. The report gives your roofer the locations.
How do you choose the testing method?
The roof decides the method. You’ll know which method we plan to use before we start.

Local flat roofs in Boxmoor
Before planning roof work on an older home, find out whether it is 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. Hemel Hempstead, which Boxmoor is part of, is one of England’s post-war new towns. Homes from the post-war decades are common in the new towns, many with low-pitched roofs in concrete tiles and flat-roofed garages or porches. Flat-roofed garages, porches and extensions from that era may have been re-covered more than once, or not at all.
The streets around a church like Church of St John the Evangelist and Attached Church Hall are frequently among the oldest in a place, and if you own one of the older houses nearby, the flat roofs on later extensions tend to wear out long before the main roof. Take a building like Boxmoor Primary School: a large flat roof with lots of outlets and rooflights has many places where a membrane can fail. Landlords with a home close to Hemel Hempstead station may find that flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

Why it’s worth a survey now in Boxmoor
Testing a new membrane before it’s covered is easier than tracing a leak later. Covered roofs are harder to test. Tradespeople may need to travel further to a smaller place like Boxmoor, so it is useful to plan roof work rather than call someone out in a hurry. Knowing early gives you time to get the right people in.
All our prices include VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. You will know the exact price before you book.

What you can safely check yourself
Look up at the roof after a storm, from ground level: 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.
What you cannot do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and a fall can be serious. That is where a survey comes in, using safe viewpoints and a drone where applicable.
