Electronic leak detection in Offham
ELD suits many waterproofing membranes on flat roofs, on homes, blocks and commercial buildings. It helps trace a leak you already have or to test a new membrane before it is 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. We survey liquid-applied waterproofing, flat roof membranes and green roofs, and the problems we are asked to look at most are breaches hidden under paving or planting and stains far from any visible defect.
Some older homes in villages like Offham are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. If you’re planning work, check with the council first. Finding out what state the roof is in gives you the facts to plan with. Listed building consent is needed for changes that affect a listed building’s special interest.
Every survey ends with a written report, with photographs, sent by email. It explains the condition of the flat roof membrane, the defects we found and what we recommend.

What you can safely check yourself
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date.
You can learn a lot from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please do not climb up for a closer look.
Offham: your questions answered
Can you look at the flat roof of a hotel or office near Offham?
Yes, commercial flat roofs are part of what we cover. For a bigger roof, you’ll get a quote based on the building.
Is my home in Offham listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. 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 this an asbestos survey?
No. Asbestos surveys and sampling are not something we do. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000.
Are you structural engineers?
No. Visible signs such as deflection or sagging are recorded, but we don’t provide calculations or an engineer’s opinion. The report will say if you need an engineer.
Does ELD include fixing the breach?
No, the test finds the breaches and your roofer repairs them. Your roofer uses the report to target the repair.
Which method do you use?
The method is chosen to suit the roof. Low-voltage methods are usually carried out on a wet roof and high-voltage methods need the membrane dry and exposed.
What will the report tell me?
It sets out what we found, why it matters and what we recommend, with photos throughout. It also says if any part of the roof couldn’t be seen safely, so you know exactly what was covered.
What affects the price in Offham
A few things affect what a survey costs:
- The shape of the roof and its details
- The roof’s overall size
- Extensions, dormers and garages with roofs of their own
- Building height and the viewpoints available
For a price for your roof in Offham, phone 07833 053749 or use the contact form and let us know about the roof. The price is agreed before a date is set.
What we need to know
You do not need to know any roofing terms. Just let us know:
- Dates you’re working to, such as exchange
- Your postcode, so we can check access and travel
- Pictures of the roof from a safe spot, if you have them
- What made you get in touch
Photos help, if you have them. Take them safely from ground level or a window, and please do not climb up for a closer look. To get started, phone 07833 053749 or drop us an email.
Electronic leak detection in Offham: local notes
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, alongside oast houses and timber-framed Wealden hall houses. Next to the main roofs there is typically a flat roof somewhere, whether on an extension, a garage or a commercial unit. The wider area around Offham has a long history of building, with Anne of Cleves House about 1.7 miles south-east. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area.
If yours is one of the older homes in the streets near Church of St Peter, the flat roofs on later extensions tend to wear out long before the main roof. If you run a hotel or guest house in or near Offham, a roof problem can mean rooms out of use. If you let a flat or house near Cooksbridge station, the flat roof over a let home is worth a look before it becomes a tenant complaint.

Why get it checked now?
Opening up a roof to hunt for a leak is disruptive. Electronic testing finds the hole first so your roofer knows where to work. Older and listed buildings around Offham may need consent and matching materials for repairs, so a defect found early gives time to plan the work properly.
What a survey costs comes down to the roof itself: how big it is, how high it is, the number of separate roofs and how safely it can be seen. We quote electronic leak detection for each roof, as the method and time depend on the roof.

Honest limits
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:
- Repairing the breaches (that’s for your roofer)
- Build-ups without a suitable layer below
- Moisture spread under the membrane

- Roof terraces and balconies
What happens on the day
Before we start, let us know why you’ve booked: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. The visit usually takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Somewhere as small as Offham, access is frequently the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- We check that the membrane and build-up suit electronic leak detection.
- We pick the low-voltage or high-voltage method that suits the roof.
- The roof is tested and any breaches are located.
- You get a report showing where each breach is, for your roofer to repair.
Getting ready for the survey
- Have any questions written down, so nothing gets missed
- Gather any invoices or paperwork from past roof work
- Let us know about parking near the property
