Common questions in Woodlands
Do you look at commercial flat roofs near Woodlands, like hotels?
Yes, commercial flat roofs are part of what we cover. For a bigger roof, you will get a quote based on the building, and roof access is agreed with you ahead of the visit.
Can parking be tricky for a visit in Woodlands?
It rarely stops a survey, but it is worth planning. Let us know what parking is available nearby, and the visit is planned around it.
Do I need to be at home?
That depends on the survey. Inside the building and in the loft, we need someone to let us in, while outside access can be discussed when booking.
Do you test for asbestos?
No. Asbestos surveys and sampling aren’t something we do. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000, with a recommendation to have a specialist asbestos surveyor check before it is disturbed.
Which method do you use?
The roof decides the method. You will know which method we plan to use before we start.
What happens after the survey?
You’ll receive the report by email, and what you do next is up to you: use it with a seller, an insurer, a roofer or a managing agent.
How do I arrange electronic leak detection in Woodlands?
The quickest way is to ring 07833 053749 or use the contact form. Let us know the address and a little about the roof, and we’ll take it from there. Surveys run on weekdays and at weekends.
About our electronic leak detection in Woodlands
Electronic testing locates holes in the waterproofing but not every way water gets in. Water coming through walls, copings, rooflights or plumbing will not show on the test. If the evidence points elsewhere, we’ll say so. The test shows breaches in the membrane, not water coming through masonry or around frames. The report makes clear what was and wasn’t tested. We will point you to the likely next step. We survey roof terraces and balconies, liquid-applied waterproofing and flat roof membranes, and people most frequently book us about holes around roof penetrations and repairs that haven’t stopped the leak.
London has a lot of flat roofs: rear additions, dormers, roof terraces and the roofs of blocks and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, and each fails in its own way. In Woodlands, as anywhere in London, the right approach depends on what the roof is made of. Older flat roofs are often felt or asphalt, newer ones rubber or GRP.
The report does not just list problems. It explains what we found, why it matters and what we recommend.

Why act early in Woodlands
Chasing a leak again and again is frustrating. A report showing the breach points gives your roofer a clear target. Behind a London parapet, a blocked gutter can sit full of water without anyone seeing it. By the time a ceiling stains, the timbers underneath may have been wet for a while.
To find out what your survey will cost, phone 07833 053749 or use the contact form and let us know about the roof. We will confirm the figure before booking.

How the survey works
When we arrive, we start by asking what you’ve noticed and what you want to find out. After that, we check everything we can see safely, using the ground, windows, the loft and a drone where it applies. Most surveys take as long as needed for the size of the roof and how it’s built, which we set out in the quote. Surveys in Woodlands can be booked for any day of the week. London parking is often by permit or pay-and-display, so it helps to know what’s near you, and to clear a path to the loft hatch. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- A report with photographs shows where each breach is.
Before we arrive
- If the roof is shared, arrange access with whoever manages the building
- Move anything stored under the loft hatch
- Make a note of anything you’d like us to look at
Arrange a survey
Getting a price is simple: just call 07833 053749 or drop us an email and give us a few details about the property and we will suggest the right survey. We confirm the price before anything is booked.
Advice
Do you need electronic leak detection in Woodlands?
Holes in a membrane frequently come from feet, tools or debris. Many are tiny, but still let water through.
Most people get in touch after spotting something like this:
- Leaks under green or ballasted roofs
- Damp inside with no sign on the roof
- Water coming in under a flat roof
- New roofs to check before paving or planting
If your home is one of the older ones in the streets near Church of St Mary the Virgin, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.
What to check before booking
- When you’ll get the report
- Is there a chance to talk the report through?
- Which viewpoints they use to see the roof
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
