Electronic leak detection for homes and businesses in Longstock
You get a report showing the location of each breach, with photographs. Your roofer can then repair those points rather than guessing. We don’t estimate repair costs; that’s for your roofer to price. A retest after repairs can check the work, where the roof still suits the method. You get a written report with photos. Typical surveys look at repairs that haven’t stopped the leak and leaks showing away from the breach, across liquid-applied waterproofing, green roofs and commercial flat roofs.
Somewhere as small as Longstock, flat roofs tend to be on extensions, garages and converted outbuildings. The checks are the same as anywhere: the covering, the edges, the upstands and where water drains away. We simply plan the journey and access beforehand. Garages and outbuildings are easy to forget, so mention any you want included as you book.
We write the report in plain English, so you don’t need to be a roofer to follow it. Each point is backed by a photograph where possible, with the urgent items made clear.

Longstock questions
Is my home in Longstock listed or in a conservation area?
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. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Is Longstock within the area you cover?
Yes. Longstock is within the area we cover, which takes in towns, villages and rural addresses. Our area covers London and South East England. Let us know about access, parking and anything unusual about getting there as you book.
What do I do with the report?
We email you the written report with photos and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
Do you use low-voltage or high-voltage testing?
The roof decides the method. You will know which method we plan to use before we start.
Can you survey at the weekend?
We survey seven days a week: Monday to Friday, Saturdays and Sundays. Just let us know the days that suit you.
How many surveys have you done?
Over 20 years and more than 5,000 surveys, across London and South East England.
Can you survey a shared roof?
Yes. Shared roofs just need a little more planning. Mention it when you get in touch and we will plan the survey around it.
What affects the price in Longstock
What a survey costs depends on the time and equipment it needs. That comes down to:
- The type of building, from a house to a block or an office
- Extensions, dormers and garages with roofs of their own
- How big the roof is
- The shape of the roof and its details
For a price for your roof in Longstock, phone 07833 053749 or use the contact form and tell us about the roof. We will confirm the figure before booking.
What we need to know
These details help when you contact us:
- The address and postcode of the property
- Anything about access we should know
- Photos of the roof, taken safely from ground level or a window
- Any deadline, such as an exchange date
You can call us seven days a week. For a price or to book, ring 07833 053749 or drop us an email.
What we do, step by step
Every visit follows the same pattern: we listen to what’s been worrying you, inspect the roof from each safe vantage point, take photographs as we go and make notes for the report. It usually takes longer on a large roof than a small one, with the construction of the roof playing a part too. Older rural homes like those around Longstock can have a main roof, lower lean-to roofs and outbuildings all joined together. We work round each section in turn, from the safest viewpoints.
- 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.
Getting ready for the survey
- Check the loft hatch can be reached
- Find any records of previous roof work
- Let us know about parking before the day
How to book
We confirm the price for your roof before you book, so you know where you stand. Electronic leak detection is quoted for your roof, because the method depends on the roof. To book, ring 07833 053749 or email us.

Practical tips
Over many surveys, some simple habits stand out as worth the effort:
- Consider ELD before paving or planting goes on
- Don’t let outlets block
- Ask contractors to protect the membrane
- Have roof specifications to hand
The report records each breach location with photos. Your roofer uses it to carry out repairs.
ELD before paving, ballast or planting goes on is worth considering. Finding breaches is simpler at that stage.

Local flat roofs in Longstock
Older buildings may be listed or sit in a conservation area. To find out, check Historic England’s list and ask the council about conservation areas. Re-roofing in different materials may need permission there. Within a mile and a half or so of Longstock there are several hotels. If you look after one, a leak through a flat roof can put a room out of use.
A roof leak in a hotel or guest house around Longstock means lost rooms as well as repairs. The streets around a church such as Church of St Mary are often among the oldest in a place, and if yours is one of the older homes nearby, flat-roofed rear additions and dormers added over the years are worth checking. If you look after a building such as Test Valley School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

Rented homes, blocks and businesses
Where a roof is shared: we need access agreed with whoever owns or manages the building. Let us know about it when booking and we will plan the visit with that in mind.
We also survey roofs for businesses and commercial landlords. Larger roofs take longer, so they’re priced to suit.
Can I check my roof myself?
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. Leave anything above ground level to a survey.
What you cannot do safely is get up close. Roofs are fragile and slippery, and falls from height are serious. That part is for a survey, using safe viewpoints and a drone where it applies.
How the survey changes by roof type
Bituminous membranes
Older felt roofs often have seams and patches where breaches occur. Testing depends on the roof.
Inverted and paved roofs
A terrace or paved roof hides the waterproofing. Whether it can be tested depends on the build-up.
