Checking the roof from ground level
A lot can be seen from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please do not climb up for a closer look.
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Don’t go up yourself.
How electronic leak detection works in St Margarets
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It works with an electrical current which can only get through the membrane at a breach. It can find holes too small to spot by eye, so your roofer can repair them. The results come in a report with photos. We survey single-ply roofs, flat roof membranes and commercial flat roofs, and common reasons people get in touch are damage from equipment installers and new membranes needing a check before handover.
Older buildings in small places like St Margarets may be listed or in a conservation area, which can shape what a new flat roof may look like. If you are planning work, check with the council first. Knowing the roof’s condition is the starting point. Listed building consent is needed for changes that affect a listed building’s special interest.
We write the report in plain English, so you don’t need to be a roofer to follow it. Each point is backed by a photograph where possible, and recommendations are put in order of urgency where relevant.

Questions from St Margarets
Will you come out to St Margarets?
Yes, we do. We survey roofs across London and the South East, from towns to the smallest villages. The journey is planned ahead, so it’s useful to know about access.
Is St Margarets in the area you cover?
Yes. We survey roofs across London and South East England, and St Margarets is part of that. You can call 07833 053749 or drop us an email with the address and some details.
Does this replace a RICS home survey?
No. We look at the roof, not the whole building, so it is not a RICS Level 2 or Level 3 survey. Many buyers have both.
Do I have to be there for the survey?
If the survey includes the loft or the inside of the building, someone needs to let us in. We’ll talk about access as you book.
Will I get photos?
Yes. We photograph the roof as we go, and the report uses them to show each finding alongside our recommendations.
What’s the best way to book?
To arrange a survey, call 07833 053749 or email us with the address, the type of property and what’s prompted the survey. We will confirm the price and agree a day with you.
Does the weather affect the survey?
Light rain is typically fine; heavy rain and wind are different. In high wind or heavy rain, a drone cannot fly and access may not be safe, so we’d move the date with you.
Rented homes, blocks and businesses
Where a roof is shared: access has to be agreed with whoever owns or manages the building. Mention it when you contact us and we will plan the survey around it.
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, putting the urgent items at the top.
Prices for electronic leak detection in St Margarets
Several things affect the price of a survey:
- How many separate roofs there are, like extensions, dormers and garages
- The size of the roof
- The type of building, from a house to a block or an office
- How tall the building is and how easy the roof is to see
To find out what your survey will cost, ring 07833 053749 or send us an email and let us know about the roof. The price is agreed before a date is set.
What we need to know
You do not need to know any roofing terms. Just let us know:
- Pictures of the roof from a safe spot, if you have them
- Why you want a survey: buying, a leak, a storm or new work
- Whether there’s a loft hatch, a shared roof or tricky access
- What kind of property and roof it is
We survey roofs seven days a week. To find a date that works for you, ring 07833 053749 or drop us an email.
What electronic leak detection looks like in St Margarets
With Lullingstone Castle about 4.5 miles south-west, St Margarets sits in an area with a long building history. Older roofs in the wider area can hide decades of patch repairs, so the detail matters. Older houses across Kent often have handmade clay or peg tiles, and many have tile-hung walls. Kent’s older buildings take in oast houses and timber-framed Wealden hall houses as well. Next to the main roofs there’s typically a flat roof somewhere, whether on an extension, a garage or a commercial unit.
If you let a flat or house near Farningham Road station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. Shop and office owners around Bluewater may find that flat roofs over shops and units are easy to forget until water comes through a ceiling. If yours is one of the older homes in the streets near Church of St Margaret of Antioch, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

How it works
Photos are taken throughout the visit, so the report shows exactly what we saw. Close-ups come from the safest viewpoint available. Most surveys take more time on a big roof than a small one, with the construction of the roof playing a part too. Somewhere like St Margarets needs a little journey planning: let us know about lanes, gates and parking. On the day, we inspect whatever is safely visible, inside and out.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We check that the membrane and build-up suit electronic leak detection.
- The testing method is chosen to suit the membrane and build-up.
- Testing runs across the roof to locate breaches in the membrane.
- We send a report with photos of each breach so your roofer can repair it.
Getting ready for the survey
- If the roof is shared, arrange access with whoever manages the building
- Leave a clear route to the loft
- Point out any leaks or damp patches

What happens if roof problems are left?
Cutting open a flat roof to find a leak can cause more damage. Electronic testing finds the hole first so your roofer knows where to work. Older and listed buildings around St Margarets may need consent and matching materials for repairs, so a defect found early gives time to plan the work properly.
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. You’ll know the figure before booking.
