Electronic leak detection for homes and businesses in Roffey
Green roofs, ballasted roofs and roofs under paving are harder to test. What sits on the membrane can affect which method will work and parts may need to be lifted. We talk this through before we quote. Any details of the build-up help, as they show what lies beneath the surface. We’ll tell you if the roof can’t be tested. Common reasons to book are leaking laps in the waterproofing and damp inside with no sign on the roof, on flat roof membranes, single-ply roofs and liquid-applied waterproofing.
In smaller places like Roffey, flat roofs are mostly on extensions, garages, porches and dormers. Even a small flat roof can let plenty of water into the room below. What it’s covered in, and how well it was laid, decides what it needs, from felt and asphalt to EPDM rubber and GRP. Ponding, splits and lifting edges are the signs to look for from a window.
The report is written in plain words, so it makes sense without any roofing background. Photographs show what each point refers to.

Roof by roof
Inverted and paved roofs
A terrace or paved roof hides the waterproofing. Whether it can be tested depends on the build-up.
Bituminous membranes
Bituminous felt and modified bitumen membranes are common. The build-up decides which method will work.

Electronic leak detection in Roffey: local notes
Older houses across Sussex often have handmade clay tiles, and many have tile-hanging on their upper walls. Some old buildings in Sussex have Horsham stone slab roofs. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops. Listing and conservation areas can both shape what roof work is allowed on an older home. Your council and Historic England’s list will tell you where you stand, ideally before any re-roofing is planned.
If you let a flat or house near Littlehaven station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies. If yours is one of the older homes in the streets near All Saints Church, the joins between later flat roofs and the old walls are where problems normally start.

Landlord and commercial surveys in Roffey
Where a roof is shared: we need access agreed with the freeholder or managing agent. Let us know about it when booking and we will plan the visit with that in mind.
Any of our surveys can be booked by landlords, agents and building managers in Roffey. To discuss a property or a block, ring 07833 053749 or drop us an email.
What we are asked to look at in Roffey
Other trades on the roof can puncture the waterproofing. Fixings, equipment and foot traffic can leave small holes.
It is worth booking a survey if you’ve seen:
- Damage from equipment installers
- Stains far from any visible defect
- Gaps at membrane joints
- Breaches around outlets and penetrations
If you look after a building such as Northolmes Junior School, schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.
What to check before booking
- What the survey will not cover
- Whether VAT is added on top
- What insurance they carry
- Whether the loft space is looked at, where there is one
What electronic leak detection does not cover
To be straight with you, there are limits to any roof survey:

Your questions about electronic leak detection in Roffey
How do I find out if my home in Roffey is listed?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Do you cover smaller places like Roffey?
Yes, we do. We cover the whole of London and South East England, from towns to the smallest villages. The journey is planned ahead, so it is useful to know about access.
How fast do I get the report?
Each package has its own report time. Basic is within 48 hours, Standard is 24–48 hours and Premium is the same day. Mention any deadline when you book.
How many surveys have you done?
We’ve completed more than 5,000 surveys, across 20+ years of surveying roofs.
Do you climb onto every roof?
Not unless it is safe. Most of what we need can be seen from safe viewpoints, the loft and, where it applies, a drone, and the report notes anything we couldn’t see.
Can you give me structural calculations?
No. We point out what can be seen, like sagging or deflection, but we do not carry out calculations or give an engineer’s opinion. If we think you need an engineer, the report says so.
How long will testing take?
It usually takes a length of time set by the roof’s area and construction, and we’ll give you a guide when quoting.
What happens on the day
Once we have finished looking, we write up our findings as a photo-illustrated written report, emailed to you. As for time on site, it normally takes a length of time set by the size of the roof and how it’s built, which we’ll explain when we quote. For a survey in Roffey, we agree the time, the access and parking before the day. Visits can be on weekdays, Saturdays or Sundays. If there are outbuildings or garages you want looked at, mention them.
- We ask about the roof, its age, its membrane and where leaks appear inside.
- The roof is assessed to see if electronic testing will work on it.
- The testing method is chosen to suit the membrane and build-up.
- We test the membrane and find where current is passing through it.
- We send a report with photos of each breach so your roofer can repair it.
Getting ready for the survey
- Gather any invoices or paperwork from past roof work
- Leave side gates unlocked
- Tell us about parking before the day
How to book
Photos help, if you have them. Pictures from ground level or a window are fine; never climb up to get a better view. To send them or to book, phone 07833 053749 or use the contact form.
Advice
Should I look at the roof myself first?
During heavy rain, look at the gutters from ground level or a window. Overflowing water can be a sign of a blockage or a gutter that has dropped.
After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Don’t go up yourself.
