About our electronic leak detection in Jarvis Brook
Green roofs, ballasted roofs and roofs under paving are harder to test. The layers on top can limit the methods we can use, and some may need lifting. We’ll discuss it with you when we quote. Any details of the build-up help because they show what’s under the surface. If testing isn’t possible, we’ll say so. We survey roof terraces and balconies, commercial flat roofs and single-ply roofs, and the problems we’re asked to look at most are stains far from any visible defect and repairs that haven’t stopped the leak.
In a small place like Jarvis Brook, a flat roof can stand in the open, so edges, upstands and laps take a beating. Felt roofs, which often last around 15–20 years, normally show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are normally the first part of a flat roof to go.
What you get is a clear record of the flat roof membrane on the day we saw it. That makes it useful now and a handy reference later, like when you want to compare after future work.

Landlords, agents and block managers in Jarvis Brook
A roof problem in a let property affects your tenants as well as the building. A survey shows what needs attention, so you can plan the work with less disruption.
Letting agents often book on a landlord’s behalf. We agree a time with the tenant beforehand.
Local flat roofs in Jarvis Brook
Older houses across Sussex often have handmade clay tiles, and many have tile-hanging on their upper walls. Horsham stone slab roofs survive on some old Sussex buildings, alongside oast houses and timber-framed Wealden hall houses. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. Historic houses like Groombridge Place, about 4.7 miles north, show how far back building in the area around Jarvis Brook goes. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material.
For an older house near a landmark such as St Michael & All Angels, the joins between later flat roofs and the old walls are where problems typically start. Landlords with a home close to Crowborough station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak.

What we look for on each type of roof
Liquid-applied waterproofing
Testing a liquid-applied roof depends on what’s beneath the coating.
EPDM rubber roofs
ELD on EPDM depends on the product and the layers. We check before we quote.
What we’re asked to look at in Jarvis Brook
If a flat roof keeps leaking after patching, the hole may be elsewhere. ELD can locate the breach more precisely.
Problems we come across often include:
- Damage from equipment installers
- Waterproofing to test before it is covered
- Holes around roof penetrations
- Leaking laps in the waterproofing
Take a building like Jarvis Brook Primary School: large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
What to check before booking
- Which parts of the roof they’ll actually see
- Whether the inside of the roof is included
- How much experience they have with roofs like yours
- Whether you can ask questions once you have the report
Tips that help
Nothing here needs a ladder. A few suggestions:
- Use boards when working on the roof
- Do not leave water getting in
- Note where leaks show inside and when
- Don’t let outlets block
Questions about the results are welcome. We will explain what was found and what it means.
Act on leaks quickly. Water under a membrane can spread.
How the survey works
Expect us to ask a few questions before we start, such as when any problem began and what work has been done before. The inspection then takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Cottages and farmhouses around Jarvis Brook often have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints, and anything we cannot see is noted.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- We work across the roof with the test equipment.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
How to prepare
- Make a note of anything you’d like us to look at
- Gather any invoices or paperwork from past roof work
- Show us where any leaks or stains appear
Book a survey
Buyers should book once an offer has been accepted, so you have the findings in time to act on them before you exchange. For any other survey, just ring 07833 053749 or use the contact form when you’re ready.

DIY checks: what’s safe
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way. That part is for a survey.
It helps to keep a record: dates of leaks, photos from the ground and any work done on the roof. Send it with your enquiry.
Jarvis Brook questions
Is my home in Jarvis Brook listed or in a conservation area?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Is Jarvis Brook within the area you cover?
Yes, Jarvis Brook is covered. We survey roofs across London and South East England, from towns to the smallest villages. The journey is planned ahead, so it is useful to know about access.
Do you carry out surveys on Saturdays and Sundays?
Visits run seven days a week in the daytime, which suits people who work during the week. Just say which days work for you.
Do you use drones?
Yes, where it is applicable. Flights depend on the weather on the day and airspace rules. We are a CAA-registered drone operator.
Do you carry professional indemnity insurance?
Professional indemnity and public liability insurance cover our surveys. Ask if you need details for a managing agent or building owner.
Can you survey in bad weather?
It can, depending on the survey. Drone flights need calm, dry weather, and thermal imaging works best with a dry roof, little wind and a sunny day beforehand. We will rearrange with you if the weather isn’t right.
Will you repair the leak?
No, our part is finding the breaches. The report gives your roofer the locations.
