Electronic leak detection near Walton on the Hill

When to book a survey in Walton on the Hill

Flat roof membranes can be punctured by foot traffic, dropped tools or debris. Some are too small to see but water still finds them.

Problems we come across often include:

  • Stains far from any visible defect
  • New roofs to check before paving or planting
  • Leaks that return after repairs
  • Leaking laps in the waterproofing

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

Choosing a roof surveyor

  • Whether the roof space is looked at, where there is one
  • Which parts of the roof they’ll actually see
  • Are they insured for the work?
  • Whether you get a written report with photos

What a good roof survey covers

Electronic leak detection in Walton on the Hill: what you get

ELD suits many waterproofing membranes on flat roofs, on homes, blocks and commercial buildings. It can be used to trace an existing leak or to test a new membrane before it’s covered. We quote for each roof based on its size and build-up. We can test on weekdays and at weekends, depending on the weather. Just ask about your roof. If you are worried about damage from equipment installers and new roofs to check before paving or planting, a survey will tell you what’s going on, on flat roof membranes, commercial flat roofs and roof terraces and balconies alike.

Somewhere as small as Walton on the Hill, flat roofs tend to be on extensions, garages and converted outbuildings. They need the same care as any town roof: the covering, the edges, the upstands and where water drains away. We simply plan the journey and access beforehand. Garages and outbuildings are easy to forget, so mention any you want included when you book.

Every survey ends with a written report, with photographs, emailed to you. It sets out the condition of the flat roof membrane, any defects and our written recommendations.

Electronic leak detection around Walton on the Hill

Many older homes in Surrey have handmade clay tiles and tile-hung upper walls. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere. The wider area around Walton on the Hill has a long history of building, with Fitznells Manor about 5 miles north. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material.

Shop and office owners around The Ashley Centre may find that flat roofs over shops and units are easy to forget until water comes through a ceiling. For an older house near a landmark such as Church of St Peter, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

Walton on the Hill is about 3 miles south-east of Ashtead, in Surrey.

Walton on the Hill: your questions answered

Is Walton on the Hill in the area you cover?

Yes, Walton on the Hill is one of the places we work. The survey and report are the same in Walton on the Hill as anywhere else.

Is Walton on the Hill within the area you cover?

Yes, Walton on the Hill is covered. We survey roofs across London and South East England, from towns to the smallest villages. The journey is planned ahead, so it helps to know about access.

How long will testing take?

Testing typically takes a time that depends on the roof’s area and construction, and we’ll give you a guide when quoting.

Does the report include photographs?

Yes, every report has them. Pictures sit next to the findings they show, which makes the report easy to follow.

When does the report arrive?

It depends on the package: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. Reports are sent by email.

Do I have to be there for the survey?

Not necessarily. An outside-only look can be arranged beforehand, but the loft and any rooms with damp need someone to let us in.

What will the report tell me?

It explains what we saw, what it means and what we’d suggest, with photos throughout. Anything we couldn’t see safely is noted too.

The survey, step by step

Time on site depends on the size and shape of the roof; as a rough guide, the survey takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. If you have questions on the day, just ask. Somewhere as small as Walton on the Hill, access is frequently the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.

  1. First, we confirm which roof areas are included.
  2. The surface is prepared for the chosen method.
  3. We work across the roof with the test equipment.
  4. We mark the breach locations in our records.
  5. The report is sent for your roofer to act on.

Before the survey

  • Note where any stains or damp appear
  • If you’re buying, check with the agent that we can get in
  • Let us know where we can park nearby

How to book

Advice

Tips that help

A few practical points come up again and again on our surveys. They apply to most roofs:

  • Use boards when working on the roof
  • Keep foot traffic on flat roofs to a minimum
  • Test new membranes before covering them
  • Share any drawings of the roof

If we think the leak isn’t coming through the membrane, the report says so, so other causes can be checked.

Act on leaks quickly. The longer water gets in, the more insulation and decking can be affected.

Leave it or get it looked at?

Repairs in the wrong place leave the leak in place. ELD shows the actual breach points. For an older or listed building in a place like Walton on the Hill, repairs may need matching materials and consent, so leaving a defect until it is urgent leaves less time to plan.

The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.
