Common questions in Frithsden
Do you cover Frithsden?
Yes, Frithsden is within the area we cover. We work right across London and South East England. You can ring 07833 053749 or drop us an email with the address and a few details, and we’ll talk through which survey suits.
Will you come out to Frithsden?
Yes, we do. Our area covers London and South East England, from towns to the smallest villages. Longer journeys are simply planned beforehand.
Can you inspect my roof with a drone?
Where it helps and the rules allow, yes. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and the airspace and weather are checked before every flight.
What’s the best way to book?
To book, phone 07833 053749 or use the contact form and let us know the address and what you need to know. We will confirm the price and find a day that suits.
Is this a RICS survey?
No. Our survey is a roof survey, not a RICS Level 2 or Level 3 survey of the whole building. It focuses on the roof and can sit alongside a RICS survey.
What’s the price of ELD?
Electronic leak detection is quoted for your roof, because the method depends on the roof. Size, build-up and access all affect the price. To get a quote, phone 07833 053749 or email us.
Can you survey in bad weather?
Light rain doesn’t normally stop a survey, and it can even help show where water is getting in. Heavy rain or strong wind can ground a drone and make the roof unsafe, so we’ll agree a new date if the weather isn’t suitable.
Electronic leak detection in Frithsden: what you get
Roofs covered with paving, ballast or planting need more thought. What sits on the membrane can affect which method will work, and some may need lifting. We’ll discuss it with you when we quote. Any details of the build-up help because they show what’s under the surface. If testing isn’t possible, we will say so. We survey roof terraces and balconies, single-ply roofs and green roofs, and people most often book us about punctures from foot traffic or tools and waterproofing to test before it’s covered.
Flat roofs on exposed homes in small places like Frithsden take more wind and rain, which is hard on edges, upstands and joins in the covering. Older felt roofs, often around 15–20 years in life, show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. On an exposed roof, the edges tend to go first.
The report records the flat roof membrane as we found it on the day. That makes it useful now and a handy reference later.

What happens on the day
The aim of the visit is simple: to see as much of the flat roof membrane as can be seen safely and record it clearly. Everything we note and photograph goes into the written report. It usually takes a length of time set by the membrane area and the build-up, which we’ll explain when we quote. For a village or hamlet like Frithsden, the journey is planned beforehand: let us know about lanes, gates and parking. The roof is looked at from ground level, from windows, from the loft where there is safe access and from the roof where it is safe.
- You let us know about the roof and where water is showing.
- 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.
- A report with photos shows where each breach is.
Preparing for the visit
- Point out any leaks or damp patches
- Move anything stored under the loft hatch
- Gather any invoices or paperwork from past roof work
Arrange a survey
Buyers should book once an offer has been accepted, so there’s time to use the report before exchange. Otherwise, simply phone 07833 053749 or drop us an email whenever suits you.
Advice
Before and after the survey
From years of surveys, a few habits stand out:
- Keep a note of leaks after rain
- Limit access to the roof
- Share any drawings of the roof
- Do not leave water getting in
The report records each breach location with photos. Pass it to your roofer to repair the breach points.
Keep outlets and gutters on flat roofs clear. Standing water puts more pressure on any weak point.
For landlords and managing agents
Shared roofs need a little more planning: access has to be agreed with whoever owns or manages the building. Let us know about it when you book and we’ll plan the survey around it.
Any of our surveys can be booked by landlords, agents and building managers in Frithsden. To discuss a property or a block, call 07833 053749 or email us.
What electronic leak detection looks like in Frithsden
Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles, with flat-roofed extensions, dormers and garages common everywhere. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops. An older home may be listed, or stand 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.
If you own a rental within reach of Berkhamsted station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. Take a building like Potten End CofE Primary School: ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. Take an older house close to Church of St Lawrence: flat-roofed rear additions and dormers added over the years are worth checking.

If in doubt, ring 07833 053749 or drop us an email and we’ll point you to the right survey before you book. The full list of what we check.
Roof types and parts we check
- Single-ply roofs
- Green roofs
- Flat roof membranes
- Liquid-applied waterproofing

- Roof terraces and balconies
Why get it checked now?
Cutting open a flat roof to find a leak can cause more damage. Electronic testing finds the hole first, so the repair can be targeted. Outbuildings and barns around Frithsden are easy to forget, but a failed roof there can spoil what’s stored inside. A quick look before winter can save a lot.
To find out what your survey will cost, call 07833 053749 or email us with the address and a few details. We’ll confirm the figure before booking.

Checking the roof from ground level
During heavy rain, look at the gutters from ground level or a window. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
It is useful to keep a record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry and it will help the survey.
