Henfield: your questions answered
Do you carry out roof surveys in Henfield?
Yes, Henfield is within the area we cover. We cover the whole of London and South East England. You can phone 07833 053749 or drop us an email with the address and a few details, and we’ll talk through which survey suits.
Do you cover smaller places like Henfield?
Yes, Henfield is covered. We cover the whole of London and South East England, and smaller places are part of that. The journey is planned ahead, so it’s useful to know about access.
Will you fly a drone over my roof?
Yes, where it’s applicable. Whether we can fly on the day depends on the weather and the airspace rules, including flight restriction zones near airports. We are a CAA-registered drone operator.
Can you test a green or ballasted roof?
It can be possible, depending on the roof. What sits on the membrane affects the method, so we check the build-up first.
Is it the same as a RICS Level 2 or Level 3 survey?
No. This is a survey of the roof only, so it is not a RICS Level 2 or Level 3 survey. It can sit alongside a RICS survey if you want both.
Can you survey a shared roof?
Yes, once access has been agreed. Roofs over flats are often shared, so we need permission from whoever owns or manages the building. We can only inspect what we are given access to.
Do you take photos of the roof?
Yes. The report includes photos of what we found.
Electronic leak detection for homes and businesses in Henfield
Our ELD testing covers flat roofs in Henfield and the rest of London and South East England. A visit normally takes a length of time set by the size of the roof and how it’s built, and we’ll give you a guide when quoting. We quote electronic leak detection for each roof, as the method and time depend on the roof. The results come in a written report with photos. We survey roof terraces and balconies, green roofs and flat roof membranes, and the problems we’re asked to look at most are stains far from any visible defect and holes around roof penetrations.
In smaller places like Henfield, flat roofs are mostly on extensions, garages, porches and dormers. They’re small, but a leak over a kitchen extension can do a lot of harm. What it is covered in, and how well it was laid, decides what it needs. From an upstairs window, look for standing water, splits and edges coming away.
The report does not just list problems. It explains what we found, why it matters and what we recommend, so you can plan your next steps.

Should I look at the roof myself first?
During heavy rain, look at the gutters from ground level or a window. Overflowing water can point to a blockage or a sagging run.
Look up at the roof after a storm, from the ground: 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.
Honest limits
We only report whatever is safely visible on the day, so there are some things a survey cannot cover:
- Roofs whose membrane or build-up is not suitable
- Repairing the breaches (that’s for your roofer)
- How wet the insulation is
If in doubt, phone 07833 053749 or email us and we’ll recommend the right survey. What our survey covers.
Roofs we survey in Henfield
- Liquid-applied waterproofing
- Green roofs
- Single-ply roofs
- Commercial flat roofs
- Roof terraces and balconies
- Flat roof membranes
The survey, step by step
We do not take risks to get a closer look. We inspect whatever is safely visible, and anything we cannot see is noted in the report. The survey usually takes longer on a large roof than a small one, with the construction of the roof playing a part too. Parking around Henfield is usually easier than in a town centre, but mention lanes, gates or long drives. Low roofs on bungalows can often be seen well from the ground, and the loft shows the rest.
- 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.
- We pick the low-voltage or high-voltage method that suits the roof.
- We test the membrane and find where current is passing through it.
- You get a report showing where each breach is, for your roofer to repair.
Before we arrive
- Gather any invoices or paperwork from past roof work
- Let us know about parking near the property
- For a flat or shared roof, check access with whoever owns or manages the building
Booking a survey
Most bookings start with a short call: phone 07833 053749 or drop us an email and we’ll ask a few questions about the roof. The price is agreed before a date is set.

Local flat roofs in Henfield
If your home is older, it’s worth knowing whether it is listed or in a conservation area before planning roof work. Listed building consent covers changes to a listed building’s special interest, and an Article 4 direction can bring extra controls in a conservation area. Handmade clay tiles and tile-hung upper walls are typical of older Sussex houses. A few old Sussex buildings still carry heavy Horsham stone slabs. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
For an older house near a landmark like St Peter's Church, the flat roofs on later extensions tend to wear out long before the main roof.

What else we do in Henfield
Do you need electronic leak detection in Henfield?
Water travels under flat roof membranes. The leak may show some distance from where water gets in which makes it hard to find by looking.
Problems we come across often include:
- Patched roofs that still leak
- Leaks through a flat roof with no obvious cause
- Damp inside with no sign on the roof
- Failed seams and laps
Take a building like St Peter's CofE Primary School: schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks.
What to check before booking
- Which parts of the roof they’ll actually see
- What’s outside the scope of the survey
- Will they check the loft as well as the outside?
- Their insurance cover
Tips that help
From years of surveys, a few habits stand out as worth the effort:
- Have roof specifications to hand
- Ask contractors to protect the membrane
- Check new waterproofing before handover
- Clear flat roof outlets regularly
Once repairs are made, the roof can be tested again if you want to check them, where the roof still suits the method.
Consider testing a new membrane before it is covered. It is easier to find holes before more layers are added.
