Electronic leak detection in Laleham

Laleham: your questions answered

Do you cover smaller places like Laleham?

Yes. Laleham is within the area we cover, which takes in towns, villages and rural addresses. We survey roofs across London and South East England. Let us know about access, parking and anything unusual about getting there when booking.

Does a conservation area affect roof work in Laleham?

The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it’s worth checking before planning any.

What’s the price of ELD?

Each roof is quoted on its size and build-up. Send us details of the roof, and call 07833 053749 or use the contact form for a quote.

Can you give me structural calculations?

No. Our survey is not a structural engineer’s report, and it does not include calculations. If we see signs that need an engineer’s opinion, we’ll recommend one.

Will you fly a drone over my roof?

Where it helps and the rules allow, yes. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and the airspace and weather are checked before every flight.

Does electronic leak detection work on all membranes?

ELD does not suit every roof. Certain membranes are conductive, and some build-ups lack a suitable layer below. We’ll tell you if yours is not suitable at the start.

How do I arrange electronic leak detection in Laleham?

Just call 07833 053749 or use the contact form. After a few questions, we confirm the price and fix a day, weekday or weekend.

How electronic leak detection works in Laleham

Electronic testing locates holes in the waterproofing but not every way water gets in. Water coming through walls, copings, rooflights or plumbing won’t show on the test. If the evidence points elsewhere, we will say so. It will not show water getting in through brickwork or around frames. The report makes clear what was and wasn’t tested. You will also know what to check next. If you are worried about leaking laps in the waterproofing and holes around roof penetrations, a survey will tell you what’s going on.

In smaller places like Laleham, flat roofs are mostly on extensions, garages, porches and dormers. They’re small, but a leak over a kitchen extension can do a lot of harm. Knowing the covering and how it was laid tells you what to expect from it. From an upstairs window, look for standing water, splits and edges coming away.

You can share the report with anyone who needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent, whichever applies.

How the survey changes by roof type

Inverted and paved roofs

If the build-up rules out ELD, we will say so.

Liquid-applied waterproofing

Small holes in liquid waterproofing may leak. Where the roof suits it, testing can find them.

Local flat roofs in Laleham

Historic houses such as Botleys Mansion, about 3.4 miles south-west, show how far back building in the area around Laleham goes. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years. Older houses across Surrey often have handmade clay tiles, and many have tile-hanging. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops.

Anyone responsible for a site like Laleham CofE VA Primary School will know that a large flat roof with lots of outlets and rooflights has many places where a membrane can fail. If you let a flat or house near Staines station, the flat roof over a let home is worth a look before it becomes a tenant complaint. If yours is one of the older homes in the streets near Church of All Saints, flat-roofed rear additions and dormers added over the years are worth checking.

Why it’s worth a survey now in Laleham

Chasing a leak again and again is frustrating. A clear record of where the breaches are helps break that cycle. Around Laleham, leaves and moss in gutters lead to overflowing water and damp walls, especially where trees overhang. Dealing with the cause is simple; drying out a wall is not.

Useful tips for Laleham property owners

Over many surveys, some simple habits stand out as worth the effort:

  • Record dates and spots where water appears
  • Keep outlets clear of debris
  • Limit access to the roof
  • Have roof specifications to hand

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

Keep people off the flat roof unless they need to be there. Many breaches come from foot traffic.

How it works

The aim of the visit is simple: to see as much of the flat roof membrane as can safely be seen and record it clearly. Notes and photos go into the written report. The visit usually takes more time on a big roof than a small one, with the construction of the roof playing a part too. In a smaller place like Laleham, parking is seldom the issue; lanes, gates and long drives are worth mentioning. Low roofs on bungalows can often be seen well from ground level, and the loft shows the rest.

  1. First, you let us know about the roof build-up and where water is showing.
  2. We check that the membrane and build-up suit electronic leak detection.
  3. We pick the low-voltage or high-voltage method that suits the roof.
  4. Testing runs across the roof to locate breaches in the membrane.
  5. The breaches are recorded with photographs in a report for your roofer.

Getting ready for the survey

  • Point out any leaks or damp patches
  • Move anything stored under the loft hatch
  • If you’re buying, check with the agent that we can get in

Booking a survey

If you are buying, it is useful to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. For any other survey, just call 07833 053749 or drop us an email when you’re ready.
