About our electronic leak detection in Mackerel's Common
You get a report showing the location of each breach with photos. Your roofer can then repair those points rather than guessing. Repair costs are not part of the report, so your roofer prices the work. A retest after repairs can check the work, where the roof still suits the method. Results come in a written report with photos. If you’re worried about holes left by work on the roof and damp inside with no sign on the roof, a survey will tell you what’s going on, on flat roof membranes, roof terraces and balconies and commercial flat roofs alike.
In a village or hamlet like Mackerel's Common, flat roofs are usually on extensions, garages, outbuildings or barn conversions. They need the same care as any town roof: outlets, upstands, edges and the covering itself. We simply plan the journey and access ahead of time. Garages and outbuildings are easy to forget, so mention any you want included when booking.
The report is written in plain words, so you do not need to be a roofer to follow it. Photos show what each point refers to, with the urgent items made clear.

Practical tips
A survey works best with a little help from you, before and after. Tips:
- Ask contractors to protect the membrane
- Keep foot traffic on flat roofs to a minimum
- Consider ELD before paving or planting goes on
- Clear flat roof outlets regularly
You receive a report showing where each breach was found, with photographs. Pass it to your roofer to repair the breach points.
ELD before paving, ballast or planting goes on is worth considering. It is easier to find holes before more layers are added.
Local flat roofs in Mackerel's Common
Older houses across Sussex frequently have handmade clay tiles, and many have tile-hanging on their upper walls. Some old buildings in Sussex have Horsham stone slab roofs. Next to the main roofs there’s usually a flat roof somewhere, whether on an extension, a garage or a commercial unit. Historic houses such as Petworth House, about 4.6 miles south-west, show how far back building in the area around Mackerel's Common goes. If your home is one of the older ones, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material.
If you let a flat or house near Billingshurst station, the flat roof over a let home is worth a look before it becomes a tenant complaint.

Do you need electronic leak detection in Mackerel's Common?
Repeated leaks after repairs suggest the real breach hasn’t been found. ELD can locate the breach more precisely.
Here are some of the things we see often:
- Failed seams and laps
- Breaches hidden under paving or planting
- Breaches around outlets and penetrations
- Stains far from any visible defect
If you own one of the older houses in the streets near The Parish Church of St John the Baptist, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

Checking the roof from ground level
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
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. Never climb onto the roof to look.
How the survey works
There is not much for you to do on the day. Show us any stains, drips or problem areas you know about, and we’ll take it from there. A typical survey takes a time that depends on the roof’s area and construction, and we’ll give you a guide when quoting. In a small place like Mackerel's Common, access is normally the main thing to plan. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Weekday and weekend visits are available.
- We start with what you know about the roof and the leak.
- We check whether the membrane and build-up suit ELD.
- We choose a low-voltage or high-voltage method to match the roof.
- We test the roof and locate any breaches.
- You get a report with photos of each breach.
Before we arrive
- Move anything stored under the loft hatch

Advice
Leave it or get it looked at?
Chasing a leak again and again is frustrating. A clear record of where the breaches are helps break that cycle. In a small place like Mackerel's Common, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Larger roofs, taller buildings and commercial roofs take longer, so the price reflects that. The price is confirmed before you book.

What does the report include?
You get our findings in writing, part by part, with photos, and ends with what we recommend. Points are put by urgency where it matters.
Do you use low-voltage or high-voltage testing?
The method is chosen to suit the roof. Low-voltage testing usually needs a wet surface, while high-voltage testing needs a dry, exposed membrane.
Can you survey at the weekend?
Surveys run on weekdays, Saturdays and Sundays. To find a day that suits you, call 07833 053749 or use the contact form.
Do you survey roofs on blocks of flats?
Yes, as long as access is agreed. The roof of a block or converted house is often shared, so we need permission from the freeholder or managing agent. We inspect only the parts we’re allowed to reach.
Can you tell me if my roof has asbestos?
No. Asbestos surveys and testing are not part of what we do. If we see materials that could contain asbestos, such as cement roof sheets or soffits on buildings from before 2000, we flag them and suggest a specialist asbestos surveyor checks them before any work.
