Flat roofs in High Cross
England has around 10,000 conservation areas and about 500,000 listed buildings. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material, so the council is the place to ask. A number of Hampshire villages keep thatched roofs on their older buildings. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Next to the main roofs there’s normally a flat roof somewhere, whether on an extension, a garage or a commercial unit.
If you look after a building such as Froxfield Church of England Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. If you let a flat or house near Petersfield station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. If you own one of the older houses in the streets near Church of St Peter, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

Electronic leak detection in High Cross: what you get
We carry out electronic leak detection on flat roofs in High Cross and across London and South East England. Testing typically takes a length of time set by the size of the roof and how it’s built, which we set out in the quote. We quote electronic leak detection for each roof, as the method and time depend on the roof. You get a written report with photos. If you’re worried about leaks showing away from the breach and leaks at pipes, outlets or fixings, we can find out what’s behind it, on single-ply roofs, liquid-applied waterproofing and roof terraces and balconies alike.
Some older homes in villages like High Cross 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.
Where we cannot see part of the flat roof membrane, the report says so. You’ll know exactly what was inspected and what wasn’t, and what we’d suggest next.

Checking the roof from ground level
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it.
You can learn a lot from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please do not climb up for a closer look.
What a survey costs
What a survey costs depends on the time and equipment it needs. That comes down to:
- Building height and the viewpoints available
- The size of the roof
- Whether it’s a home or a commercial building
- How many separate roofs there are, such as extensions, dormers and garages
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. The price is confirmed before booking.
What we need to know
You do not need to know any roofing terms. Just tell us:
- Dates you’re working to, such as exchange
- Where the property is, with the postcode
- Where any leaks, stains or damp patches show inside
- The kind of building and roof involved
If you are buying, it helps to book soon after your offer is accepted, so there is time to use the report before exchange. For any other survey, just call 07833 053749 or use the contact form when you are ready.
Honest limits
In fairness, there are limits to any roof survey:
- How wet the insulation is
- Carrying out the repair work
- Some conductive membranes
If you are not sure which survey you need, ring 07833 053749 or send us an email and we will give you a straight answer. The full list of what we check.

High Cross: your questions answered
Does a conservation area affect roof work in High Cross?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Do you cover High Cross?
We do. The survey and report are the same in High Cross as anywhere else, and visits run on weekdays and weekends.
Do you test for asbestos?
No. Asbestos surveys and sampling are not something we do. Where a material might contain it, like old cement sheets on a building from before 2000, the report flags it, with a recommendation to have a specialist asbestos surveyor check before it’s disturbed.
Which method do you use?
The method is chosen to suit the roof. Low-voltage testing normally needs a wet surface and high-voltage methods need the membrane dry and exposed.
Can every flat roof be tested?
Not every roof is suitable. Some membranes conduct electricity, and some build-ups lack a suitable layer below. We will tell you if yours isn’t suitable before testing.
Do I have to be there for the survey?
It depends on what we need to see. For inside areas and the roof space, someone has to give us access; we will agree the details as you book.
Does ELD include fixing the breach?
No, the test finds the breaches and your roofer repairs them. The report gives your roofer the locations.
Tips that help
These tips come from what we see on roofs every week, before and after a survey:
- Stay off the flat roof unless needed
- Check new waterproofing before handover
- Avoid repeated repairs without finding the cause
- Note where leaks show inside and when
You receive a report showing where each breach was found, with photos. Pass it to your roofer to repair the breach points.
ELD before paving, ballast or planting goes on is worth considering. Finding breaches is simpler at that stage.
How it works
A survey visit follows a simple order: we listen to what’s been worrying you, look at the roof from every safe viewpoint, take photos as we go and make notes for the report. Most visits take more time on a big roof than a small one, and the build-up of the roof makes a difference too. Somewhere like High Cross needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. On the day, we inspect whatever is safely visible, inside and out.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- The report is sent for your roofer to act on.
Getting ready for the survey
- Find any records of previous roof work
- Leave a clear route to the loft
- Point out any leaks or damp patches
Booking a survey
Photos help, if you have them. Pictures from ground level or a window are fine; never climb up to get a better view. To get started, ring 07833 053749 or email us.
