Flat roof survey in Thorley Street, Hertfordshire
Know where you stand with the flat roof before you spend money on it. We carry out flat roof surveys in Thorley Street.
- Failed upstands where the roof meets a wall
- Blisters and bubbles in the covering
- Outlets that hold water back
The survey, step by step
Every visit follows the same pattern: we listen to what’s been worrying you, inspect the roof from every safe viewpoint, photograph what we find and record our findings for the written report. It usually takes about 1–2 hours for a small flat roof at home, and longer for a large commercial one. In a hamlet or village like Thorley Street, a postcode does not always lead to the right gate, so a few directions, or a note of a nearby landmark, help us arrive on time. After that, the survey runs as it would anywhere.
- We start with the details: the address, the roof’s use and any leaks or stains.
- We view the roof from ground level, 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.
- Where there is safe access, we look at the ceilings and spaces below for signs of water.
- We send a written report with photos, the defects we found and what we recommend.
Getting ready for the survey
- If you’re buying, let the agent know when we’re coming
- Dig out any old roof reports or invoices
- Move anything stored under the loft hatch

How a flat roof survey works in Thorley Street
Our Basic Survey, from £150, gives you a visual inspection with photographs and written recommendations. The Standard Survey, from £250, adds moisture detection and a structural check. On a flat roof, moisture readings can help show whether water has got under the covering. Bigger commercial roofs are priced on their size and access. Common reasons to book are gaps at upstands and abutments and blocked or damaged outlets, on EPDM rubber, single-ply membranes and felt flat roofs.
Older buildings in small places like Thorley Street may be 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. Finding out what state the roof is in gives you the facts to plan with. Listed building consent is needed for changes that affect a listed building’s special interest.
You can share the report with anyone who needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent, whichever applies.

Signs you need a flat roof survey in Thorley Street
Ponding keeps the covering wet and wears it faster. It usually comes from poor falls, a blocked outlet or a deck that has dipped. Leaves and silt from nearby trees can soon choke an outlet.
Signs worth acting on include:
- Signs of deflection in the roof deck
- Blisters and bubbles in the covering
- Cracked or split membrane
- Edge trims that have lifted or split
The streets around a church such as Parish Church of St James the Great are frequently among the oldest in a place, and if yours is one of the older homes nearby, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.
Before you book anyone
- Do they have a CAA Flyer ID and Operator ID for drone work?
- How long they’ve been surveying roofs
- How soon the report will arrive
- Is there a chance to talk the report through?
Prices for flat roof surveys in Thorley Street
What a survey costs depends on the time and equipment it needs. The main factors are:
- How many separate roofs there are, like extensions, dormers and garages
- House, block, shop or office
- The roof’s overall size
- The height of the building and how the roof can be seen safely
Prices start from £150, including VAT, for a Basic Survey. The Standard Survey starts from £250 and the Premium Survey from £400. You will know the price for your survey before booking.
Booking your survey
A few details help us point you to the right survey and price. When you get in touch, it’s useful to mention:
- Any marks or damp showing indoors
- The property’s address and postcode
- The reason for the survey, like buying, a leak or storm damage
- The type of building and roof, such as pitched or flat
Surveys can be booked for weekdays, Saturdays or Sundays. To arrange a day that suits you, call 07833 053749 or email us with the address and the days you’d prefer.
What you can safely check yourself
Your own check is a good start, but it is not a survey. From the ground, valleys, flashings and the backs of chimneys are often out of sight.
It helps to keep a record: dates of leaks, photos from the ground and any work done on the roof. Share it with us when booking, as it helps us focus the survey.
Different roofs, different checks
Single-ply membranes
On single-ply roofs, the welds between sheets are the key detail. We look at seams, corners and the joints around outlets and upstands.
EPDM rubber
EPDM is a synthetic rubber membrane, often laid in a single sheet on smaller roofs. We check the laps, the edges, the corners and any punctures.
Local flat roofs in Thorley Street
The wider area around Thorley Street has a long history of building, with Much Hadham Palace about 3.6 miles west. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
For site and facilities teams at buildings such as Thorley Hill Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. For landlords with property near Bishops Stortford station, the flat roof over a let home is worth a look before it becomes a tenant complaint.

Thorley Street: your questions answered
Is Thorley Street in the area you cover?
We do. Every survey there gets the same written report with photos.
Is Thorley Street within the area you cover?
Yes, smaller places are covered as well as towns. We survey roofs across London and the South East. Just mention lanes, gates or anything else about the route as you book.
What does ponding on a flat roof mean?
Standing water a day or two after rain typically needs attention. The cause may be the outlets, the falls or the deck. We check each of these and record what we find.
What insurance do you have?
Our cover is professional indemnity plus public liability, and we can provide details if a managing agent needs them.
I live in a flat. Can you survey the roof?
Yes, as long as access is agreed. Roofs over flats are often shared, so the freeholder or managing agent needs to agree access. We inspect only the parts we are allowed to reach.
Can you tell me how long my flat roof will last?
A precise figure isn’t something we give, because it depends on upkeep, weather and how the roof was laid. Our report describes the condition and what needs doing, and when.
Is a flat roof survey the same as a building survey?
No. It is a closer look at the flat roof, not a survey of the whole property. It works alongside a RICS home survey, not instead of one, and structural calculations need a structural engineer.

Shared roofs need a little more planning: access has to be agreed with whoever owns or manages the building. Mention it when you get in touch and we’ll plan the survey around it.
