Electronic leak detection for homes and businesses in North End
You get a report showing the location of each breach with photos. It tells your roofer exactly where to repair instead of hunting for the leak. Repair costs aren’t part of the report; that’s for your roofer to price. A retest after repairs can check the work if the build-up allows. Results come in a written report with photos. If you’ve noticed leaks at pipes, outlets or fixings and leaking laps in the waterproofing, a survey will tell you what’s going on, on single-ply roofs, flat roof membranes and liquid-applied waterproofing alike.
Around North End, many homes have a garden room, garage or outbuilding with a flat roof. They’re rarely looked at until something gets wet. It is worth mentioning them as you book, so the visit can include them. Felt, rubber and GRP coverings on garages and outbuildings age in just the same way as the main roof’s.
We write the report in plain English, so it makes sense without any roofing background. Each point is backed by a photograph where possible, and recommendations are put with the most urgent first where relevant.

DIY checks: what’s safe
What you can’t do safely is get up close. Roofs are fragile and slippery. That part is for a survey, using safe viewpoints and a drone where it applies.
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can point to a blockage or a sagging run.
What we look for on each type of roof
Liquid-applied waterproofing
Small holes in liquid waterproofing may leak. Where the roof suits it, testing can find them.
Green and ballasted roofs
Some layers may need lifting for testing. We discuss this before quoting.
What a survey costs
A few things affect what a survey costs:
- The size of the roof
- House, block, shop or office
- Height and safe access
- Extensions, dormers and garages with roofs of their own
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.
Booking your survey
To price your survey accurately, we’ll ask about:
- What’s prompted the survey
- The kind of building and roof involved
- How the loft is reached, if there is one
- Your timetable, such as an exchange date
To book a survey, ring 07833 053749 or drop us an email with the address and what you’d like to know about the roof. You’ll know the price before anything is booked.
What electronic leak detection looks like in North End
North End is within about 1 mile of the coast, and being near the sea means more wind and salt than a roof inland would face. Coastal wind works at the edges of flat roofs, and salt air wears metal trims and fixings. Older buildings may be listed or sit in a conservation area. To find out, check Historic England’s list and ask the council about conservation areas. In either case, a change of roofing material may need consent.
If you own a rental within reach of Hilsea station, the flat roof over a let home is worth a look before it becomes a tenant complaint. If your house is among the older ones in the streets near St. Mark’s, flat-roofed rear additions and dormers added over the years are worth checking. For site and facilities teams at buildings such as Corpus Christi Catholic Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

What else we do in North End
The survey, step by step
Once we have finished looking, we write up our findings in a report with photos, emailed to you. On timing, it normally takes as long as needed for the size of the roof and how it’s built, which we’ll explain when we quote. With a bit of garden around a house, as there frequently is around North End, the roof can be viewed from several angles. Let us know if any side is fenced off or hard to reach. Inside, the loft is looked at where it can be reached safely.
- We agree the area to be tested.
- We get the roof ready for testing.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
How to prepare

North End questions
Is the coastal weather around North End hard on roofs?
Generally, yes: wind and salt air take more of a toll near the sea. Exposed details such as ridges, verges, flashings and metal fixings are the ones to watch, and North End is within about 1 mile of the coast.
How do I find out if my home in North End is listed?
The council and Historic England’s list are the places to check. It’s worth checking before planning roof work, as both can affect what’s allowed.
Do you survey roofs on blocks of flats?
Yes, once access has been agreed. Roofs over flats are frequently shared, so we need permission from whoever owns or manages the building. We inspect only the parts we’re allowed to reach.
Does ELD work under paving or planting?
In some cases. It depends on the build-up and the layers above the membrane and parts may need to be lifted. We will discuss it before we quote.
Does someone need to be in?
If the survey includes the loft or the inside of the building, someone needs to let us in. Access is agreed with you as you book.
What’s the best way to book?
To arrange a survey, ring 07833 053749 or email us with the address, the type of property and what’s prompted the survey. We will confirm the price and agree a day with you.
How much does electronic leak detection cost?
Electronic leak detection is quoted for your roof, because the method depends on the roof. The price depends on the roof’s size and build-up. To get a quote, ring 07833 053749 or email us.
