Flat roofs in Catisfield
The coast is about 2 miles or less from Catisfield, where sea air brings more salt and stronger wind than inland. Coastal wind works at the edges of flat roofs, and salt air wears metal trims and fixings. Thatch survives on some older buildings in Hampshire’s villages. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
Take an older house close to Church of St Peter: the flat roofs on later extensions tend to wear out long before the main roof. Anyone responsible for a site like Ranvilles Infant School will know that schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.

Electronic leak detection for homes and businesses in Catisfield
There are different ELD methods. Low-voltage methods usually need a wet roof surface, while high-voltage testing needs a dry, exposed membrane. The right method depends on the membrane and the build-up of the roof and we explain which we’ll use. We will say if your roof doesn’t suit either method before any testing starts. If you’ve noticed leaks through a flat roof with no obvious cause and holes left by work on the roof, we can find out what’s behind it, on commercial flat roofs, green roofs and single-ply roofs alike.
In a smaller place like Catisfield, some flat roofs sit in the open, so wind catches loose edges and trims. Sun on a flat roof also ages felt and bitumen. The signs are splits, blisters and edges coming away. Standing water that lingers for days after rain is another sign worth watching for.
We keep jargon out of it: if work is needed, the report says so clearly, along with how urgent it is.

- Commercial flat roofs
- Flat roof membranes
- Green roofs
- Liquid-applied waterproofing
- Roof terraces and balconies
The survey, step by step
On the day, we begin with a quick chat about the roof and anything that’s worrying you. After that, we look at everything we can see safely, using the ground, windows, the loft and a drone where it applies. Most surveys take as long as needed for the membrane area and the build-up, which we’ll explain when we quote. Being in a smaller place like Catisfield doesn’t change how the visit works: outside, inside and from any safe vantage point, in that order. It’s useful to show us anything you’ve already noticed.
- First, you let us know about the roof build-up and where water is showing.
- We confirm whether the roof is suitable for electronic testing.
- We pick the low-voltage or high-voltage method that suits the roof.
- Testing runs across the roof to locate breaches in the membrane.
- The breaches are recorded with photographs in a report for your roofer.
How to prepare
- Let us know about parking near the property
- Leave a clear route to the loft
- Have keys ready for side gates, garages or roof access doors

Catisfield questions
Does a conservation area affect roof work in Catisfield?
We cannot confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
Is the coastal weather around Catisfield hard on roofs?
Near the coast, roofs face more wind and more salt than further inland. Salt is hard on nails, clips and metal flashings, while strong wind lifts anything already loose.
How long does electronic leak detection take?
The roof’s size and build-up decide how long it takes. We’ll give you an idea when we quote.
How do I arrange electronic leak detection in Catisfield?
Simply call 07833 053749 or email us. After a few questions, we confirm the price and fix a day, weekday or weekend.
Are you insured?
Our cover is professional indemnity plus public liability.
Do you use low-voltage or high-voltage testing?
It depends on the membrane and the build-up. Low-voltage methods are typically carried out on a wet roof and high-voltage methods need the membrane dry and exposed.
What happens after the survey?
You’ll receive the report by email, and what you do next is up to you: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Why get it checked now?
Leaks left running can wet the insulation and deck. Locating it early helps limit the damage. Blocked gutters on homes around Catisfield overflow and soak walls, especially where trees overhang. It’s easy to sort the cause early and slow to dry a damp wall.

ELD is easier on a new roof before it’s covered.
What a survey costs
Prices always include VAT. The things that change the price are:
- Extra roofs, like extensions, dormers or garages
- Features like valleys, chimneys, dormers and parapets
- Commercial roofs and larger buildings
- How big the roof is
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how safely it can be seen. Electronic leak detection is quoted for your roof, because the method depends on the roof.
