Questions from Crofton
Will parking be an issue for a roof survey in Crofton?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available as you book.
Do you carry out roof surveys in Crofton?
We do. Every survey there gets the same written report with photographs, and visits run on weekdays and weekends.
Are you structural engineers?
No. We point out what can be seen, such as sagging or deflection, but we’re not structural engineers and don’t carry out calculations. Where an engineer is needed, we say so in the report.
Do you take photos of the roof?
Yes, every report has them. Each finding is shown in a picture where possible, which makes the report easy to follow.
What’s the price of ELD?
Each roof is quoted on its size and build-up. Send us details of the roof. Just phone 07833 053749 or use the contact form for a quote.
Do I have to be there for the survey?
Someone needs to let us in if we’re looking inside or in the loft. Access is agreed with you as you book.
Is it the same as a RICS Level 2 or Level 3 survey?
No. Our survey is a roof survey, not a RICS Level 2 or Level 3 survey of the whole building. It focuses on the roof, so it sits alongside a building survey rather than replacing it.
Electronic leak detection for homes and businesses in Crofton
ELD is a way of pinpointing breaches in a flat roof’s waterproofing membrane. It uses a small electrical current which can only get through the membrane at a breach. That lets us locate holes that are too small to see, so your roofer can repair them. You get a report with photographs of each breach found. If you’ve noticed new roofs to check before paving or planting and failed seams and laps, a survey will tell you what’s going on, on liquid-applied waterproofing, single-ply roofs and green roofs alike.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Outlets, upstands against parapet walls and joins with the main roof are frequent culprits. In a converted house in Crofton, the roof above may belong to the building rather than one flat.
The report does not just list problems. For each finding, it explains what it is, why it matters and what we’d recommend.

What affects the cost of electronic leak detection
Prices always include VAT. The things that change the price are:
- The type of building, from a house to a block or an office
- Height and safe access
- How complicated the roof is, with its valleys, chimneys and parapets
- How many separate roofs there are, like extensions, dormers and garages
To find out what your survey will cost, call 07833 053749 or use the contact form and tell us about the roof. The price is agreed before a date is set.
What we need to know
Some details help us suggest the right survey and price. When you contact us, let us know:
- The address and postcode of the property
- The reason for the survey, such as buying, a leak or storm damage
- Dates you are working to, such as exchange
- Where water is showing inside, if it is
For a price for electronic leak detection in Crofton, phone 07833 053749 or email us. A few details about the property and the roof help us price the survey accurately.
What we do, step by step
Photos are taken throughout the visit, so you can see in the report what we found and where. We take close-ups from wherever is safe. A typical visit takes more time on a big roof than a small one, and the build-up of the roof makes a difference too. In converted houses and mansion blocks, the loft hatch is often on a shared landing. If that applies to your building, it helps to agree access with the neighbours or the managing agent first. Everything else is planned around the building, not the postcode.
- First, you let us know about the roof build-up and where water is showing.
- We check that the membrane and build-up suit electronic leak detection.
- The testing method is chosen to suit the membrane and build-up.
- The roof is tested and any breaches are located.
- You get a report showing where each breach is, for your roofer to repair.
How to prepare
- Buyers: confirm access with the estate agent or seller
- Move anything stored under the loft hatch
- Mention any parking restrictions on your street
Booking a survey
Every survey is priced before it is booked, so you know the cost up front. Electronic leak detection is quoted for your roof, because the method depends on the roof. For a price for your roof, ring 07833 053749 or use the contact form.
Advice
Rented homes, blocks and businesses
Landlords, agents and building managers in Crofton and across Greater London can book any of our surveys. To discuss a property or a block, ring 07833 053749 or drop us an email.
An agent can book and manage the survey for a landlord, with the report sent to whoever needs it. We agree a time with the tenant beforehand.
How the survey changes by roof type
Inverted and paved roofs
We will tell you if your inverted or paved roof isn’t suitable.
EPDM rubber roofs
Certain rubber membranes are conductive, which can rule out some methods. We will say if the test will not work.
What you can safely check yourself
After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.
A DIY look is useful, but it isn’t a survey. From the ground, valleys, flashings and the backs of chimneys are often out of sight, and those are details a survey looks at closely.
Why act early in Crofton
Testing a new membrane before it is covered is easier than tracing a leak later. Covered roofs are harder to test. Behind a London parapet, a blocked gutter can sit full of water without anyone seeing it. When the stain finally shows, the damage underneath is often older than it looks.
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.

What electronic leak detection looks like in Crofton
Outer London has a good many Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, frequently with hipped roofs in clay or concrete tiles. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. Historic houses such as Bromley Palace, about 3.2 miles north-west, show how far back building in the area around Crofton goes. If you own one of the older houses, expect a mix of original materials and later repairs on the roof, and the council can say whether a home is in a conservation area.
Landlords with a home close to Orpington station may find that the flat roof over a let home is worth a look before it becomes a tenant complaint. The streets around a church such as Church of Jesus Christ of Latter-Day Saints are often among the oldest in a place, and if your house is among the older ones nearby, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. Shop and office owners around The Mall may find that outlets and upstands on commercial flat roofs are the places to check before trouble starts.
