About our electronic leak detection in Denvilles
Electronic leak detection works on many flat roof membranes, on homes, blocks and commercial buildings. It helps trace a leak you already have or to test a new membrane before it’s covered. Each roof is quoted on its size and build-up. We can test on weekdays and at weekends, depending on the weather. Just ask about your roof. If you’ve noticed patched roofs that still leak and leaks under green or ballasted roofs, a survey will tell you what’s going on, whatever the roof.
Outbuildings, garden rooms and garages in places like Denvilles often have flat roofs of their own. They’re easy to forget, but water through a garage roof can spoil whatever is stored inside. If you want them looked at too, mention them when booking, 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.
The report works through the roof section by section, from the main slopes down to the gutters and outlets, each with a short note and a photograph. It records what’s sound as well as what isn’t.

What electronic leak detection looks like in Denvilles
Denvilles lies within about 1 mile of the sea, where sea air brings more salt and stronger wind than inland. On a flat roof near the sea, edge trims and upstands take the brunt of the wind, and metal parts corrode faster. There are several hotels within about a mile and a half of Denvilles. If you look after one, a leak through a flat roof can put a room out of use.
For hotels and guest houses around Denvilles, a roof problem found early is far less disruptive than one found by a guest, so it is worth knowing the roof’s condition. Warblington Castle lies about 0.7 miles south, so building around Denvilles goes back a long way. Older homes nearby may have later flat-roofed extensions or dormers, frequently re-covered more than once. Take an older house close to St Thomas à Becket Church: later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.

Practical tips
You do not need to be a roofer to help. Here’s what helps most:
- Test new membranes before covering them
- Find the breach before more patching
- Do not let outlets block
- Note where leaks show inside and when
Keep the report with the roof’s records. It is a dated record of the membrane’s condition.
Consider testing a new membrane before it is covered. Finding breaches is simpler at that stage.
Can I check my roof myself?
Look up at the roof after a storm, from ground level: 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.
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
Rented homes, blocks and businesses
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan.
A roof problem in a let property affects your tenants as well as the building. A survey helps you spot issues early and plan the work around your tenants.
How the survey works
On the day, we start by asking what you’ve noticed and what you want to find out. After that, we check everything we can see safely, using the ground, windows, the loft and a drone where it applies. The survey typically takes longer on a large roof than a small one, with the construction of the roof playing a part too. Being in a smaller place like Denvilles does not change how the visit works: outside, inside and from any safe vantage point, in that order. Point out any stains, cracks or loose pieces you’ve spotted.
- First, we confirm which roof areas are included.
- We get the roof ready for testing.
- We work across the roof with the test equipment.
- We mark the breach locations in our records.
- You receive the results to pass to your roofer.
Getting ready for the survey
- Clear the way to the loft hatch
- Find any records of previous roof work
- If you’re buying, check with the agent that we can get in
Book a survey
Getting a price is simple: just call 07833 053749 or drop us an email and give us a few details about the property and we’ll point you to the right survey. We confirm the price before anything is booked.
