About our electronic leak detection in Crayford
You get a report showing the location of each breach, with photographs. It tells your roofer exactly where to repair instead of hunting for the leak. Repair costs are not 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, roof terraces and balconies and flat roof membranes, and the problems we’re asked to look at most are damp inside with no sign on the roof and waterproofing to test before it’s covered.
Outbuildings, garden rooms and garages in places like Crayford often have flat roofs of their own. They’re rarely looked at until something gets wet. It’s worth mentioning them when booking, so the visit can include them, along with the main flat roof. Smaller roofs use the same coverings as bigger ones, from felt to rubber and GRP, and age in the same way.
We write the report in plain English, so it makes sense without any roofing background. Photos show what each point refers to, and recommendations are put with the most urgent first where relevant.

Why act early in Crayford
Water trapped under a membrane can soak insulation and decking. Locating it early helps limit the damage. Arranging work in a smaller place like Crayford is easier with notice than in an emergency. A survey gives you that notice.
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. You’ll know the figure before booking.

Your questions about electronic leak detection in Crayford
Will you come out to Crayford?
Yes, we do. We survey roofs across London and South East England, from towns to the smallest villages. Longer journeys are simply planned in advance.
Do you carry out roof surveys in Crayford?
We do. The survey and report are the same in Crayford as anywhere else, and visits run on weekdays and weekends.
How experienced are you?
We’ve completed more than 5,000 surveys, across 20+ years of surveying roofs, and 98% of clients are satisfied.
Is my roof suitable for ELD?
Not every roof is suitable. Certain membranes are conductive, and some build-ups lack a suitable layer below. If your roof won’t work, we’ll say so at the start.
Is it the same as a RICS Level 2 or Level 3 survey?
No. We are experienced roof surveyors, and our survey covers the roof rather than the whole building. If you need a full building survey, you’ll need a RICS survey as well.
Do you look in the roof space?
If there is a loft and safe access to it, yes. From inside, the underside of the roof often shows damp, staining or daylight that can’t be seen from outside.
How long does electronic leak detection take?
It depends on the size of the roof and its build-up. You will know roughly how long before we start.
Roof by roof
Liquid-applied waterproofing
Liquid-applied coatings form a seamless layer but holes and thin areas can occur. Whether ELD works depends on the coating and build-up.
Inverted and paved roofs
A terrace or paved roof hides the waterproofing. Suitability depends on the layers.

How we price electronic leak detection
Prices always include VAT. What changes the price is:
- The type of building, from a house to a block or an office
- Extra roofs, like extensions, dormers or garages
- The height of the building and how the roof can safely be seen
- Features like valleys, chimneys, dormers and parapets
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 we need to know
To price your survey accurately, we’ll ask about:
- Pictures of the roof from a safe spot, if you have them
- How the loft is reached, if there is one
- Any marks or damp showing indoors
- Your timetable, such as an exchange date
Surveys can be booked for weekdays, Saturdays or Sundays. To find a date that works for you, call 07833 053749 or use the contact form.
How the survey works
Every roof is different, but as a rough guide the survey takes a time that depends on the roof’s area and construction, and we’ll give you a guide when quoting. If you have questions on the day, just ask. Homes around Crayford often have gardens on more than one side, which gives us room to step back and see the roof. Mention any side of the property we cannot get to. The loft, where there’s safe access, completes the picture.
- We agree the area to be tested.

Related advice
Do you need electronic leak detection in Crayford?
Roofs covered with paving, ballast or planting hide the membrane. Electronic methods can help on some of these roofs, depending on the build-up.
These are some of the problems a survey can pick up:
- Stains far from any visible defect
- Water coming in under a flat roof
- Holes left by work on the roof
- Waterproofing to test before it is covered
If you own a rental within reach of Crayford station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Questions to ask before booking
- Whether the loft space is looked at, where there is one
- Whether VAT is in the quoted price
- What experience they bring
- What they won’t be able to tell you
What this survey cannot tell you
Before booking, it’s worth knowing what a survey won’t do:
- The extent of water in the insulation
- Roofs whose membrane or build-up isn’t suitable
- Sections we can’t safely access
If you are not sure which survey you need, phone 07833 053749 or drop us an email and we’ll give you a straight answer before you book. The full list of what we check.

Local flat roofs in Crayford
Across Kent, older roofs are frequently handmade clay or peg tiles, and tile-hanging on upper walls is a familiar sight. Kent’s older buildings take in oast houses and timber-framed Wealden hall houses as well. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops. The wider area around Crayford has a long history of building, with Hall Place and Gardens about 0.9 miles west. If you own one of the older houses, expect a mix of original materials and later repairs on the roof.
The streets around a church such as Church of St Paulinus are often among the oldest in a place, and if you own one of the older houses nearby, flat-roofed rear additions and dormers added over the years are worth checking. If you look after a building such as Wentworth Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
