Upper Upnor Electronic Leak Detection
Find out the condition of the flat roof membrane at your property in Upper Upnor from an independent roof surveyor. We visit on weekdays and at weekends.

- Leaks under green or ballasted roofs
- Damp inside with no sign on the roof
Useful tips for Upper Upnor property owners
Nothing here needs a ladder. A few suggestions:
- Test new membranes before covering them
- Do not let outlets block
- Don’t leave water getting in
- Use boards when working on the roof
File the report with your roof paperwork. It’s a dated record of the membrane’s condition.
Act on leaks quickly. The longer water gets in, the more insulation and decking can be affected.
How electronic leak detection works in Upper Upnor
ELD suits many waterproofing membranes on flat roofs, on homes, blocks and commercial buildings. It can be used to trace an existing leak or to test a new membrane before it’s covered. We quote for each roof based on its size and build-up. We can test on weekdays and at weekends when conditions allow. Tell us about your roof to find out more. We are frequently asked to look into repairs that haven’t stopped the leak and damage from equipment installers, across green roofs, flat roof membranes and commercial flat roofs.
Flat roofs on exposed homes in small places like Upper Upnor take more wind and rain, which is hard on edges, upstands and joins in the covering. Felt roofs, which frequently last around 15–20 years, normally show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are usually the first part of a flat roof to go.
The report is written in plain words, so you don’t need to be a roofer to follow it. Photos show what each point refers to, with the urgent items made clear.

What this survey can’t tell you
Our survey is not a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- Parts of the roof covered by fixed equipment
- Repairing the breaches (that’s for your roofer)
- Build-ups without a suitable layer below
If in doubt, phone 07833 053749 or use the contact form and we’ll recommend the right survey. The full list of what we check.
What this survey covers
- Roof terraces and balconies
- Green roofs
- Flat roof membranes
- Liquid-applied waterproofing
- Single-ply roofs
- Commercial flat roofs
Landlords, agents and block managers in Upper Upnor
If the property is let, the agent or a tenant can let us in, at a time agreed ahead of time. We survey seven days a week, which can make access easier.
Letting agents often book on a landlord’s behalf, and the report can go to both. Access is agreed with the tenant in advance.
DIY checks: what’s safe
It helps to keep a record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry and it will help the survey.
Look up at the roof after a storm, from the ground: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Do not go up yourself.

FAQs for Upper Upnor
Is my home in Upper Upnor listed or in a conservation area?
We cannot confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case.
Can you look at the flat roof of a hotel or office near Upper Upnor?
Yes, commercial flat roofs are part of what we cover. Larger commercial roofs are quoted for the building, and roof access is agreed with you before the visit.
Do you climb onto every roof?
Not always. Safety comes first, and fragile or steep roofs can’t always be walked on. Safe viewpoints, the loft and a drone where it applies let us see the rest.
Is Upper Upnor in your area?
Yes. We carry out electronic leak detection in Upper Upnor.
Do you use drones?
Where it helps and it’s safe, yes. Whether we can fly on the day depends on the weather and the airspace rules, including flight restriction zones near airports. We hold a CAA Flyer ID and Operator ID.
How much time does ELD need?
It usually takes longer on a large roof than a small one, with the construction of the roof playing a part too.
Can you give me structural calculations?
No. Our survey is not a structural engineer’s report, and it does not include calculations. If we see signs that need an engineer’s opinion, we will recommend one.
Flat and commercial roofs around Upper Upnor
Upper Upnor lies within about 2 miles of the sea, so there is more wind and more salt in the air than further inland. Salt in the air is hard on metal flashings and fixings, and wind catches any loose edge on a flat roof. There are several hotels within about a mile and a half of Upper Upnor. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use.
Restoration House, about 1.6 miles south-west, is one of the historic houses in the wider area around Upper Upnor. On a period home nearby, any flat roof is likely to be a later addition with its own lifespan. If you look after a building like Wainscott Primary School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. For an older house near a landmark such as St Philip & St James, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
Upper Upnor is about 2 miles north-east of Rochester, in Medway. Upper Upnor is one of many places we visit across Medway, for homes and businesses alike. Across Medway, we cover Upper Upnor. You can also see our page for Maidstone.

What happens if roof problems are left?
ELD before paving, ballast or planting goes on is simpler. Covered roofs are harder to test. Older and listed buildings around Upper Upnor may need consent and matching materials for repairs, so a defect found early gives time to plan the work properly.

How the survey works
Once we’ve finished looking, we write up our findings in a report with photos. As for time on site, it typically takes a length of time set by the membrane area and the build-up, and we’ll give you a guide when quoting. Older rural homes like those around Upper Upnor can have a main roof, lower lean-to roofs and outbuildings all joined together. We work round each section in turn, from the safest viewpoints.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- We choose a low-voltage or high-voltage method to match the roof.
- We test the roof and locate any breaches.
- You get a report with photos of each breach.
Before the survey
- Leave a clear route to the loft
- For flats, check roof access has been agreed
- Show us where any leaks or stains appear
