Landlord and commercial surveys in Three Bridges
Businesses and commercial landlords can book us too, from shops and offices to industrial units. Larger roofs take longer, and they’re priced for the size.
If the property is let, the agent or a tenant can let us in, at a time agreed beforehand. We survey on weekdays, Saturdays and Sundays, which helps when tenants work during the week.
Electronic leak detection for homes and businesses in Three Bridges
ELD finds breaches in the membrane but not every way water gets in. Leaks from walls, copings, rooflights or pipes need other checks. We’ll tell you if we think the leak is coming from somewhere else. The test shows breaches in the membrane, not water coming through masonry or around frames. Our report keeps that distinction clear. You’ll also know what to check next. We are often asked to look into leaks through a covered membrane and repairs that haven’t stopped the leak, across liquid-applied waterproofing, flat roof membranes and green roofs.
In a smaller place like Three Bridges, some flat roofs sit in the open, where wind can catch loose edges and trims. Sun on a flat roof also ages felt and bitumen. Splits, blisters and lifting edges are what to look out for. A flat roof that still holds water days after rain is also worth a closer look.
The report works through the roof section by section, from the coverings down to the gutters, each with a short note and a photo. It records what’s sound as well as what is not.

How it works
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. In total, it takes more time on a big roof than a small one, with the construction of the roof playing a part too. Homes around Three Bridges often have gardens on more than one side, which gives us room to step back and see the roof. Let us know if any side is fenced off or hard to reach. The loft, where there’s safe access, completes the picture.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- The test method is chosen to suit the roof.
- We test the roof and locate any breaches.
- A report with photos shows where each breach is.
Before we arrive
- If you are buying, let the agent know when we’re coming

Related advice
Should I look at the roof myself first?
During heavy rain, look at the gutters from the ground or a window. Overflowing water can point to a blockage or a sagging run.
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Share it with us when you book.
Useful tips for Three Bridges property owners
There’s plenty you can do without going near the roof. Here’s what helps most:
- Act on new leaks promptly
- Do not keep patching the same spot
- Let us know about the membrane and build-up if you know it
- Ask contractors to protect the membrane
The report records each breach location with photos. Your roofer uses it to carry out repairs.
Act on leaks quickly. The longer water gets in, the more insulation and decking can be affected.
Leave it or get it looked at?
Not every leak is in the membrane. ELD helps rule the membrane in or out, so other causes can be checked. On a bungalow or cottage around Three Bridges, the roof sits close to the rooms below, so a small leak can mark a ceiling within a few storms. Finding the cause first saves a second job inside.
All our prices include VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. You will know the price for the job before booking.

FAQs for Three Bridges
Does a conservation area affect roof work in Three Bridges?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Do you cover smaller places like Three Bridges?
We do. A small place gets exactly the same survey as a big one.
Will you repair the leak?
No. ELD is testing only. The report shows where each breach is for your roofer to repair.
Do I have to be there for the survey?
Not always. An outside-only look can be arranged beforehand, but the loft and any rooms with damp need someone to let us in.
What is electronic leak detection?
It uses an electrical current to find breaches in a flat roof membrane. A breach lets the current through so we can pinpoint it.
Do you use drones?
Where it helps and it is safe, yes. Whether we can fly on the day depends on the weather and the airspace rules, and we check for restrictions near airports before flying. We’re a CAA-registered drone operator.
Is it a structural engineer’s report?
No. We are roof surveyors, not structural engineers, and it doesn’t include calculations. We will recommend an engineer if we see signs that call for one.

Other services in Three Bridges

Inverted and paved roofs
On inverted roofs, insulation sits above the membrane and that changes how testing works.
Bituminous membranes
Many flat roofs use bitumen-based membranes. Whether ELD suits them depends on the build-up.
Flat roofs in Three Bridges
Many older homes in Sussex have handmade clay tiles and tile-hung walls. A few old Sussex buildings still carry heavy Horsham stone slabs. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops. Historic houses such as Gravetye Manor, about 4.9 miles south-east, show how far back building in the area around Three Bridges goes. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof, and the council can say whether a home is in a conservation area.
If you look after a shop, office or commercial unit, for instance near County Mall, flat roofs over shops and units are easy to forget until water comes through a ceiling. If you look after a building such as Pound Hill Junior School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. For an older house near a landmark like St Barnabas', any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
