Electronic leak detection in Crow: local notes
Avon Tyrrell House, about 2.4 miles south-east, is one of the historic houses in the wider area around Crow. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first. Thatch survives on some older buildings in Hampshire’s villages. Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops.
If you look after a building such as Ringwood Junior School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.

Electronic leak detection in Crow
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It works with an electrical current that passes through the membrane only where there’s a breach. It can find holes too small to spot by eye, so your roofer can repair them. You get a photo-illustrated written report of each breach found. Typical surveys look at repairs that haven’t stopped the leak and gaps at membrane joints, across roof terraces and balconies, green roofs and single-ply roofs.
Some older homes in villages like Crow are listed or in a conservation area, which can shape what a new flat roof may look like. If you’re planning work, check with the council first. Knowing the roof’s condition is the starting point. Changes that affect a listed building’s special interest need listed building consent.
It is not only a list of defects. For each finding, it explains what it is, why it matters and what we’d recommend, so you can decide what to do next.

Questions from Crow
Do you cover smaller places like Crow?
Yes, smaller places are covered as well as towns. Our area covers London and South East England. Just mention lanes, gates or anything else about the route when you book.
Do you cover Crow?
Yes, Crow is one of the places we work. The survey and report are the same in Crow as anywhere else, and visits run on weekdays and weekends.
Does the weather affect the survey?
Some surveys depend on the weather more than others. Drone flights need calm, dry weather, and thermal imaging works best with a dry roof, little wind and a sunny day beforehand. If the conditions aren’t right, we’ll talk to you about another date.
Can you test a green or ballasted roof?
It can be possible, depending on the roof. Covered roofs limit the methods we can use, so we check the build-up first.
Do you need to get into the loft?
Yes, where the survey calls for it and there is safe access. Inside, we look for damp, staining, gaps and sagging.
Is it a structural engineer’s report?
No. Visible signs like deflection or sagging are recorded, but we do not provide calculations or an engineer’s opinion. If one is needed, the report says so.
Are you insured?
We hold professional indemnity and public liability insurance, for every survey we carry out.

How the survey works
Expect us to ask a few questions before we start, about the roof’s history, any leaks and past repairs. Then the inspection itself takes a length of time set by the size of the roof and how it’s built, which we’ll explain when we quote. Older roofs in small places like Crow can have low, tight loft spaces, so tell us about the loft hatch and any ladder. Only areas that can be reached safely are inspected.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- The roof is assessed to see if electronic testing will work on it.
- The testing method is chosen to suit the membrane and build-up.
- Testing runs across the roof to locate breaches in the membrane.
- You get a report showing where each breach is, for your roofer to repair.
Before the survey
- Have any paperwork from past roof work to hand
- Have any questions written down, so nothing gets missed
- Note where any stains or damp appear

Advice
Landlord and commercial surveys in Crow
Shared roofs need a little more planning: we need access agreed with whoever owns or manages the building. Mention it when you contact us and we will plan the survey around it.
With a portfolio of properties, you can book surveys for several addresses. To arrange surveys for several addresses, ring 07833 053749 or email us.
What happens if roof problems are left?
Cutting open a flat roof to find a leak can cause more damage. Electronic testing finds the hole first, so the repair can be targeted. Older and listed buildings around Crow may need consent and matching materials for repairs, so leaving a defect until it is urgent leaves less time to plan.
For a price for your roof in Crow, phone 07833 053749 or use the contact form with the address and a few details. The price is agreed before a date is set.

Can I check my roof myself?
Your own check is a good start, but it is not a survey. You won’t see flashings, valleys or the backs of chimneys properly from ground level, and those are details a survey looks at closely.
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
