Electronic leak detection near Downley

What happens if roof problems are left?

Repairs in the wrong place leave the leak in place. Testing shows where the membrane is actually breached. In a small place like Downley, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Larger roofs, taller buildings and commercial roofs take longer, so they’re priced to match. The price is confirmed before booking.

Why us?

  • Drone flown under a CAA Flyer ID and Operator ID
  • Over 20 years’ experience
  • Over 5,000 surveys carried out
  • An independent view of the roof

How electronic leak detection works in Downley

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, so your roofer prices the work. Testing again after repairs can confirm the breaches have been dealt with if the build-up allows. You get a written report with photos. We survey single-ply roofs, liquid-applied waterproofing and flat roof membranes, and people most frequently book us about patched roofs that still leak and leaking laps in the waterproofing.

Flat roofs on exposed homes in small places like Downley take more wind and rain, which is hard on edges, upstands and joins in the covering. Felt roofs, which frequently last around 15–20 years, typically show it first. Rubber and GRP last longer, though trims and joints still need a look. On an exposed roof, the edges tend to go first.

The report is written in plain words, so it makes sense without any roofing background. Photos show what each point refers to, and recommendations are put by urgency where it matters.

Can I check my roof myself?

A DIY look is useful, but it isn’t 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.

What you can’t do safely is get up close. Roofs are fragile and slippery, and a fall can be serious. That’s where a survey comes in.

Signs you need electronic leak detection in Downley

Water travels under flat roof membranes. The stain inside can be far from the hole which makes it hard to find by looking.

These are some of the problems a survey can pick up:

  • New roofs to check before paving or planting
  • Repairs that haven’t stopped the leak
  • Punctures from foot traffic or tools
  • A flat roof leak that cannot be traced

For landlords with property near High Wycombe station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.

Questions to ask before you book

  • How they plan to inspect the roof safely
  • Do they have a CAA Flyer ID and Operator ID for drone work?
  • Is VAT included in the price?
  • What’s outside the scope of the survey

What to expect from a roof survey

Tips that help

Small things make a difference. Our tips:

  • Limit access to the roof
  • Record dates and spots where water appears
  • Consider ELD before paving or planting goes on
  • Avoid repeated repairs without finding the cause

If anything in the report is not clear, ask us. We’ll explain what was found and what it means.

Limit foot traffic on flat roofs. Feet and dropped tools are a common cause of holes.

Honest limits

We only report whatever is safely visible on the day, so there are some things a survey can’t cover:

  • Moisture spread under the membrane
  • Parts of the roof covered by fixed equipment
  • Leaks from plumbing or windows

If in doubt, phone 07833 053749 or send us an email and we’ll point you to the right survey. The full list of what we check.

What we look at

  • Flat roof membranes
  • Green roofs
  • Single-ply roofs
  • Roof terraces and balconies
  • Liquid-applied waterproofing
  • Commercial flat roofs

What electronic leak detection looks like in Downley

Hughenden Manor, about 0.8 miles east, is one of the historic houses in the wider area around Downley. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area. A number of Buckinghamshire villages keep thatched roofs on their older buildings. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.

Shop and office owners around Eden may find that the flat roofs over shops and commercial units are worth checking before a leak, not after. If your house is among the older ones in the streets near St. James the Great, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

Your questions about electronic leak detection in Downley

Will you come out to Downley?

Yes, smaller places are covered as well as towns. Our area covers London and South East England. Let us know about access, parking and anything unusual about getting there when you book.

Do you cover Downley?

How experienced are you?

Over 5,000 surveys so far, over more than 20 years, and 98% of clients are satisfied.

What happens next?

The report comes by email, and you decide the next step: use it with a seller, an insurer, a roofer or a managing agent.

Will you go up on the roof?

Only where it’s safe to do so. We inspect everything that’s safely in view: from the ground, from windows and vantage points, from the roof space, from the roof itself where safe and by drone where it applies. The report says if anything couldn’t be seen.

What insurance do you have?

Our surveys are covered by professional indemnity and public liability insurance. Ask if you need details for a managing agent or building owner.

Does ELD include fixing the breach?

No, the test finds the breaches and your roofer repairs them. Your roofer uses the report to target the repair.

What happens on the day

We work from the outside in: outside views come first, then the loft space if there’s safe access. In total, it takes a time that depends on the roof’s area and construction, and we’ll give you a guide when quoting. Cottages and farmhouses around Downley often have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints, and anything we cannot see is noted.

  1. We start by finding out what the roof is made of and where it leaks.
  2. We confirm whether the roof is suitable for electronic testing.
  3. The method depends on the membrane and what sits above and below it.
  4. We test the membrane and find where current is passing through it.
  5. You get a report showing where each breach is, for your roofer to repair.

Before the survey

  • If you’re buying, check with the agent that we can get in
  • Dig out any old roof reports or invoices
  • Agree roof access with the managing agent if it is shared

How to book

Every survey is priced before it’s booked, so you know the cost up front. We quote electronic leak detection for each roof, as the method and time depend on the roof. For a price for your roof, ring 07833 053749 or send us an email.
