Flat roofs in Ashendon
Historic houses such as Waddesdon Manor, about 2.3 miles north-east, show how far back building in the area around Ashendon goes. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first. Thatch survives on some older buildings in Buckinghamshire’s villages. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
If you let a flat or house near Haddenham & Thame Parkway station, the flat roof over a let home is worth a look before it becomes a tenant complaint.

About our electronic leak detection in Ashendon
Some flat roofs can’t be tested electronically. Certain membranes conduct electricity and some roofs don’t have a suitable layer beneath the membrane. If your roof is not suitable, we’ll tell you before any testing. 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 cannot give results. If you’ve noticed waterproofing to test before it’s covered and leaks through a flat roof with no obvious cause, we can find out what’s behind it, on single-ply roofs, roof terraces and balconies and liquid-applied waterproofing alike.
Some older homes in villages like Ashendon are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. Check with the council before planning any change of material. Knowing the roof’s condition is the starting point. Changes that affect a listed building’s special interest need listed building consent.
The report records the flat roof membrane as we found it on the day. It is useful straight away, and a good reference for later.

The survey, step by step
It helps to start with what’s prompted the survey: buying, a leak, storm damage, new work or just wanting to know where things stand. It helps us focus on what matters most to you. Most visits take more time on a big roof than a small one, with the construction of the roof playing a part too. In a small place like Ashendon, 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.
- First, we confirm which roof areas are included.
- The surface is prepared for the chosen method.
- Testing runs across the agreed area.
- Each breach found is located and recorded.
- You receive the results to pass to your roofer.
Preparing for the visit
- Keep pets inside or away from the areas we are looking at
- Show us where any leaks or stains appear
- Make sure we can get to the back of the property
Arrange a survey
Most bookings start with a short call: phone 07833 053749 or email us. You’ll have a price before anything is arranged.

When to book a survey in Ashendon
Holes in a membrane often come from feet, tools or debris. Some are too small to see but water still finds them.
Things that often lead to a survey include:
- Waterproofing to test before it’s covered
- A flat roof leak that can’t be traced
- Stains far from any visible defect
- Breaches hidden under paving or planting
If you live in an older home near Parish Church of St Mary the Virgin, the flat roofs on later extensions tend to wear out long before the main roof.
Before booking any roof surveyor
- How soon the report will arrive
- Will the report include photos?
- What the survey won’t cover
- Do they have a CAA Flyer ID and Operator ID for drone work?
DIY checks: what’s safe
The one thing to avoid is getting up close. Roofs are fragile and slippery. That part is for a survey.
It helps to keep a record: when leaks happen, ground-level photos and any past roof work. Share it with us when booking, as it helps us focus the survey.
Common questions in Ashendon
Do you cover Ashendon?
Yes, Ashendon is one of the places we work. The survey and report are the same in Ashendon as anywhere else, and visits run on weekdays and weekends.
Do you cover smaller places like Ashendon?
Yes, Ashendon is on our map. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Will you check the loft?
Yes, where the survey calls for it and there’s safe access. We look for staining, damp, daylight and signs of movement.
Do you survey roofs on blocks of flats?
Yes, once access has been agreed. Roofs over flats are often shared, so we need permission from whoever owns or manages the building. We inspect only the parts we are allowed to reach.
Are you structural engineers?
No. Visible signs such as deflection or sagging are recorded, but we do not provide calculations or an engineer’s opinion. The report will say if you need an engineer.
Can you survey at the weekend?
Visits run seven days a week in the daytime. Just say which days work for you.
How experienced are you?
Over 5,000 surveys so far, over more than 20 years, and 98% of clients are satisfied.
Landlords, agents and block managers in Ashendon
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan.
We also survey roofs for businesses and commercial landlords, from shops and offices to industrial units. Bigger roofs take more time, and they’re priced for the size.
Before and after the survey
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Check new waterproofing before handover
- Do not keep patching the same spot
- Ask contractors to protect the membrane
- Keep a note of leaks after rain
Keep the report with the roof’s records. It shows the condition of the membrane on that date.
Clear flat roof outlets regularly. Standing water puts more pressure on any weak point.
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. Matching old materials, like handmade tiles or stone slates, can take time to source. That is one more reason to find defects before they become urgent.
Every price we give includes VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. We confirm the exact price before booking.
