How electronic leak detection works in Guildford
Electronic leak detection works on many flat roof membranes over offices, units, blocks of flats and homes. It helps trace a leak you already have or to test a new membrane before it is covered. We quote for each roof based on its size and build-up. Testing can be carried out on weekdays, Saturdays or Sundays, depending on the weather. Just ask about your roof. We’re often asked to look into leaks showing away from the breach and leaks through a covered membrane, across liquid-applied waterproofing, green roofs and commercial flat roofs.
Blocks of flats in places the size of Guildford usually have a shared flat roof, looked after by a managing agent, a residents’ company or the building owner. A leak in the top-floor flat is frequently the first sign of a problem with the membrane. The earlier the cause is found, the less damage it does. Let us know who manages the building, as access to a shared roof has to be arranged.
Where we cannot see part of the flat roof membrane, the report says so. You will know exactly what was inspected and what wasn’t, and what we’d suggest next.

Electronic leak detection in Guildford: local notes
Guildford has a number of hotels within about a mile and a half. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use. Many older homes in Surrey have handmade clay tiles and tile-hung upper walls. A few of Surrey’s oldest buildings have heavy Horsham stone slab roofs. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops.
Anyone responsible for a site like Sandfield Primary School will know that schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. If you live in an older home near Church of St John the Evangelist, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. Landlords with a home close to London Road (Guildford) station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak.
Guildford is about 27 miles south-west of London, in Surrey. Houses, flats, blocks and commercial buildings in Guildford can all book electronic leak detection, with a written report and photographs every time. Our Surrey coverage includes Guildford.

Around Guildford
Typical jobs here are in homes near The King's Head pub, Guildford High School and Surrey Maths School.

Other landmarks nearby include Guildford Castle (0.9 miles south) and Guildford House (0.8 miles south). Open spaces near Guildford include Silent Pool and Pewley Hill.
Checking the roof from ground level
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way, and falls from height are serious. That part is for a survey, using safe viewpoints and a drone where applicable.
Your own check is a good start, but it is not a survey. From ground level, valleys, flashings and the backs of chimneys are often out of sight, and those are details a survey looks at closely.
Practical tips
Nothing here needs a ladder. Our suggestions:
- Avoid repeated repairs without finding the cause
- Act on new leaks promptly
- Keep a note of leaks after rain
- Test new membranes before covering them
Once repairs are made, the roof can be tested again if you want to check them if the build-up allows.
Keep outlets and gutters on flat roofs clear. Water that sits on the roof finds breaches faster.
FAQs for Guildford
Is my home in Guildford listed or in a conservation area?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Do you carry out roof surveys in Guildford?
Yes, Guildford is one of the places we work. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
Is the repair part of the test?
No. ELD is testing only. You get the breach locations with photos for your roofer to repair.
Can you survey at the weekend?
Surveys run on any day of the week. To arrange a date, call 07833 053749 or drop us an email.
What’s the price of ELD?
We quote for each roof individually. Send us details of the roof. Just ring 07833 053749 or email us for a quote.
Do you look in the roof space?
Where it’s relevant to the survey and there’s safe access, yes. A clear path to the hatch helps, and if the loft cannot be reached safely, the report says so.
Are you structural engineers?
No. Visible signs such as deflection or sagging are recorded, but we do not provide calculations or an engineer’s opinion. The report will say if you need an engineer.
What happens on the day
We will ask a few questions first, such as when any problem began and what work has been done before. Then the inspection itself takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Visits in a place the size of Guildford range from flats and family homes to offices and blocks. Access is the part that changes most from one building to the next, so it’s agreed before the day. Surveys can be booked for any day of the week.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
Before we arrive

Businesses and commercial landlords can book us too, including offices, shops and units. Bigger roofs take more time, so they’re priced to suit.

When you need someone else
Without opening up the roof, some things stay hidden, so a survey has limits:
- Sections we can’t safely access
- Fixing the holes we find
- Some conductive membranes
