Electronic leak detection in Coldwaltham
Not every flat roof suits electronic testing. Certain membranes conduct electricity, and some build-ups lack the layer the test needs below the membrane. If your roof is not suitable, we will tell you before any testing. Telling us what you know about the roof’s membrane and layers helps, such as drawings or specifications. It avoids arranging a test that cannot give results. If you are worried about waterproofing to test before it’s covered and leaking laps in the waterproofing, we can find out what’s behind it, on green roofs, commercial flat roofs and single-ply roofs alike.
In a village or hamlet like Coldwaltham, flat roofs are usually on extensions, garages, outbuildings or barn conversions. The checks are the same as anywhere: the covering, the edges, the upstands and where water drains away. The journey and access are planned beforehand. If there are outbuildings or garages with flat roofs, mention them as you book.
The report doesn’t just list problems. For each finding, it explains what it is, why it matters and what we’d recommend.

What happens on the day

A typical visit takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Around Coldwaltham, older homes can have small or awkward roof spaces, so let us know about the loft hatch and any ladder. We only go where it is safe.
- We agree the area to be tested.
- The surface is prepared for the chosen method.
- We work across the roof with the test equipment.
- We mark the breach locations in our records.
- The report is sent for your roofer to act on.

Advice
Signs you need electronic leak detection in Coldwaltham
On a flat roof, water spreads under the waterproofing. The stain inside can be far from the hole, so tracing it by eye is difficult.
Typical things we’re asked to look at include:
- Repairs that haven’t stopped the leak
- New roofs to check before paving or planting
- Damp inside with no sign on the roof
- Gaps at membrane joints
Take a building like St James' CofE Primary School: large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
Before you book any roof surveyor
- Their report turnaround times
- What happens after the report arrives
- Their track record with similar roofs
- Will they check the loft as well as the outside?

Flat roofs in Coldwaltham
The wider area around Coldwaltham has a long history of building, with Old Place Manor about 2 miles north-east. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material. In Sussex, older roofs are often handmade clay tile, frequently with tile-hanging on the walls below. Horsham stone slab roofs survive on some old Sussex buildings. Next to the main roofs there is normally a flat roof somewhere, whether on an extension, a garage or a commercial unit.
Landlords with a home close to Pulborough station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak. The streets around a church such as The Parish Church of St Giles are often among the oldest in a place, and if yours is one of the older homes nearby, flat-roofed rear additions and dormers added over the years are worth checking.
