Sandon questions
Do you cover Sandon?
Yes. We work right across London and South East England, and Sandon is part of that. Just ring 07833 053749 or use the contact form and let us know about the property, and we’ll talk through which survey suits.
How do I find out if my home in Sandon is listed?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you’re planning to re-roof in a different material.
Which days do you carry out surveys?
We survey seven days a week: weekdays, Saturdays and Sundays. Tell us which days suit you as you book.
Should I worry about standing water on my flat roof?
Ponding is worth looking into. It frequently means a blocked outlet, poor falls or a dipping deck, and water that sits wears the covering sooner. We record where it sits and the likely cause.
How long have you been surveying roofs?
We’ve been surveying roofs for over 20 years and have carried out more than 5,000 surveys across London and South East England.
Is it a structural engineer’s report?
No. We’re experienced roof surveyors, and visible signs such as sagging are noted, but we do not provide calculations or an engineer’s opinion. If one is needed, the report says so.
What happens next?
We email you the written report with photographs and recommendations. It’s yours to share with a seller, insurer, roofer or managing agent, whichever applies.
About our flat roof survey in Sandon
Each flat roof is looked at from the safest viewpoints we have: on the roof where it’s safe, from windows and higher ground, and from the rooms below where we can reach them. We don’t walk on fragile rooflights or fragile roof sheeting. If part of the roof cannot be seen or reached safely, the report says so, so you know exactly what was covered. If you’ve noticed raised blisters across the surface and damaged trims at the roof edge, a survey will tell you what’s going on, on EPDM rubber, single-ply membranes and felt flat roofs alike.
In a small place like Sandon, a flat roof can stand in the open, so edges, upstands and laps take a beating. Felt roofs, which often last around 15–20 years, usually show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are normally the first part of a flat roof to go.
Findings are set out part by part, from the main slopes down to the gutters and outlets, each with a short note and a photograph. It records what’s sound as well as what isn’t.

Practical tips
Some practical points come up on survey after survey. They apply to most roofs:
- Look for standing water a day after rain
- Watch the ceilings below the flat roof for stains
- Plan a survey before the covering reaches the end of its usual life
- Check that new brackets or units haven’t damaged the covering
For landlords and building managers, the report is a dated record of the roof’s condition. It’s useful when planning upkeep and setting budgets, and it gives a baseline to compare against next time.
Check the roof from a window after a downpour. Water still lying a day or two later is worth getting looked at.

Flat roof surveys in Sandon: local notes
There are about 500,000 buildings on England’s list of listed buildings, and around 10,000 conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material, so check with the council. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates, and flat-roofed additions turn up almost everywhere. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
For landlords with property near Ashwell & Morden station, the flat roof over a let home is worth a look before it becomes a tenant complaint. If you look after a building such as Sandon Junior Mixed and Infant School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

How it works
We photograph the roof as we go, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available, including by drone where it is applicable and the weather allows. Most surveys take about one to two hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. Older roofs in small places like Sandon can have low, tight loft spaces, so it helps to know whether there is a loft hatch and how easy it is to reach. We only go where it’s safe.
- You let us know about the roof, its covering if you know it, and any leaks.
- We view the roof from the ground, from windows and from the roof where it is safe to do so.
- Every part of the roof we can see is looked at: covering, falls, upstands, outlets, trims and rooflights.
- We check the rooms or spaces under the roof for staining where we can reach them.
- The findings are written up with photos and recommendations and emailed to you.
How to prepare
- Have keys ready for side gates, garages or roof access doors
- If the roof is shared, arrange access with whoever manages the building
- Let us know about parking before the day
Arrange a survey
Photos help, if you have them. Take them safely from ground level or a window; never climb up to get a better view. To get started, phone 07833 053749 or email us.
Advice
What we’re asked to look at in Sandon
Water that doesn’t drain sits on the roof and speeds up wear. Blocked outlets, poor falls and a sagging deck are the usual causes. Leaves and silt from nearby trees can soon choke an outlet.
It’s worth booking a survey if you’ve seen:
- Raised blisters across the surface
- Signs of deflection in the roof deck
- Upstands pulling away from walls
- Splits and cracks in the covering
Take an older house close to Church of All Saints: the flat roofs on later extensions tend to wear out long before the main roof.
Before booking any roof surveyor
- Are they insured for the work?
- What happens after the report arrives
- What the report includes, and whether it has photos
- How much experience they have with roofs like yours
Why act early in Sandon
Most flat roofs are out of sight, so they’re easy to forget. Many owners only find out a roof is worn out when water comes through. A survey every few years stops that from catching you out. In a small place like Sandon, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A small, low roof with good viewpoints takes less time than a tall, complicated one, and the package you pick makes a difference too. We’ll give you the figure before anything is booked.
What you get with us
- Covered by professional indemnity and public liability insurance

Can I check my roof myself?
Look up at the roof after a storm, from ground level: 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.
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, and look for staining, damp timber or daylight coming through.
