FAQs for Mersham
Will you come out to Mersham?
Yes. Mersham is within the area we cover, which takes in towns, villages and rural addresses. We work right across London and South East England. Just mention lanes, gates or anything else about the route as you book.
Is my home in Mersham listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. The answer matters most when a change of material is on the cards.
Can you test a green or ballasted roof?
In some cases. The layers on top and the build-up below decide it, and some may need lifting. We talk this through first.
Which days do you carry out surveys?
Surveys can be booked for any day of the week: Monday to Friday, Saturdays and Sundays. Just tell us the days that suit you.
Does this replace a RICS home 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, so it sits alongside a building survey rather than replacing it.
Will you photograph what you find?
Yes. Photographs are taken throughout the survey, and the report uses them to show each finding alongside our recommendations.
What will the report tell me?
It works through the roof part by part, in writing and with photos, and ends with what we recommend. Points are put by urgency where it matters.
Electronic leak detection for homes and businesses in Mersham
Some flat roofs cannot be tested electronically. Certain membranes conduct electricity and some roofs do not have a suitable layer beneath the membrane. We’ll say if ELD will not work on your roof at the start. Telling us what you know about the roof’s membrane and layers helps, including drawings, specifications or the roofer’s paperwork. It avoids arranging a test that can’t give results. If you’re worried about holes left by work on the roof and breaches hidden under paving or planting, we can find out what’s behind it.
In a village or hamlet like Mersham, flat roofs are usually on extensions, garages, outbuildings or barn conversions. The checks are the same as anywhere: outlets, upstands, edges and the covering itself. The journey and access are planned beforehand. Garages and outbuildings are easy to forget, so mention any you want included as you book.
The report records the flat roof membrane as we found it on the day. That makes it useful now and a handy reference later.

- Leaks from plumbing or windows

- Flat roof membranes
- Green roofs
- Single-ply roofs

- Commercial flat roofs
- Liquid-applied waterproofing
What a survey costs
Every roof is different, so prices are confirmed before you book. These are the things that affect it:
- Whether it’s a home or a commercial building
- How many separate roofs there are, such as extensions, dormers and garages
- Chimneys, valleys, parapets and other details
- How tall the building is and how easy the roof is to see
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. You’ll know the figure before booking.
Helping us price your survey
Some details help us recommend the right survey and price. When you contact us, tell us:
- Where water is showing inside, if it is
- What’s prompted the survey
- The style of property, from a terrace to a block
- How the loft is reached, if there is one
Most bookings start with a short call: phone 07833 053749 or use the contact form. You’ll have a price before anything is arranged.

Why it is worth a survey now in Mersham
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. In a place like Mersham, a barn or garage roof left to fail puts whatever is inside at risk. It’s worth including them in a survey before a winter does the damage.
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how it can be reached and seen safely. We quote electronic leak detection for each roof, as the method and time depend on the roof.
Why choose Independent Roof Survey in Mersham
- CAA-registered drone operator (Flyer ID and Operator ID)

Before and after the survey
Small things make a difference, both for the survey and for the roof itself. Some pointers:
- Avoid repeated repairs without finding the cause
- Make sure trades protect the waterproofing
- Consider ELD before paving or planting goes on
- Do not let outlets block
If we think the leak is not coming through the membrane, the report says so, so other causes can be checked.
Act on leaks quickly. The longer water gets in, the more insulation and decking can be affected.
How the survey changes by roof type
Liquid-applied waterproofing
Testing a liquid-applied roof depends on what’s beneath the coating.
Green and ballasted roofs
Parts of the covering may have to come up. We discuss this before quoting.
What happens on the day
Once we have finished looking, we write up our findings in a report with photos, emailed to you. On timing, it typically takes longer on a large roof than a small one, and the build-up of the roof makes a difference too. Cottages and farmhouses around Mersham often have roofs at several levels, with lean-tos and outbuildings attached. Each part is looked at from wherever it can safely be seen, and anything we can’t see is noted.
- You let us know about the roof and where water is showing.
- The roof is assessed for suitability first.
- 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 the survey
- Have any paperwork from past roof work to hand
- Unlock side gates and any roof access doors
- Jot down any questions you want answered
How to book
Every survey is priced before it’s booked, so you know the cost up front. We quote electronic leak detection for each roof, as the method and time depend on the roof. To book, phone 07833 053749 or email us.
