How a chimney survey works in Thorley
Our survey covers the structure of the stack and its weathering details. It’s not a flue inspection, a chimney sweep or a gas safety inspection. If you use a fire or a gas appliance, the flue should be checked by a sweep or a Gas Safe registered engineer as appropriate. We’ll tell you if we see anything that suggests they should take a look. We survey shared and party-wall stacks, flaunching and lead flashings, and the problems we’re asked to look at most are eroded joints in the brickwork and flaunching that has broken away.
Somewhere as small as Thorley, homes are often older cottages and farmhouses, with outbuildings and some newer houses. Older roofs may be clay tile, slate, stone or thatch, frequently with chimneys that have stood a long time. We report on whatever is safely visible, and thatch is a specialist material. Chimneys and lead flashings on old roofs often need the most attention.
We keep jargon out of it: where something needs attention, it says so plainly.

Should I look at the roof myself first?
Look up at the roof after a storm, from the ground: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Leave anything above ground level to a survey.
You can learn a lot from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Please do not climb up for a closer look.
What affects the cost of chimney surveys
What a survey costs depends on the time and equipment it needs. That comes down to:
- House, block, shop or office
- How big the roof is
- The number of roofs, including extensions and garages
- The height of the building and how the roof can be seen safely
We offer three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, with VAT included. The price for your roof depends on its size, access and what you’d like to know.
Getting in touch
We will usually ask about:
- Pictures of the roof from a safe spot, if you have them
- Your postcode, so we can check access and travel
- When you need the report by
- Where water is showing inside, if it is
Photos help, if you have them. Take them safely from ground level or a window. To get started, call 07833 053749 or send us an email.
Do you need a chimney survey in Thorley?
Stacks that were used for open fires for many years can weaken from the inside. Flue gases and damp can break down the mortar, sometimes more on one side than the other, which is one reason stacks start to lean.
Here are some of the things we see often:
- Staining on walls around the chimney
- Signs that a stack is leaning
- Gaps in the mortar around the pots
- Lifted or split lead flashings
For an older house near a landmark such as Parish Church of St James the Great, its chimney, valleys and lead work are likely to be the parts that need attention first.
Choosing a roof surveyor
- How they plan to inspect the roof safely
- What the survey will not cover
- What the report includes, and whether it has photographs
- Whether the roof space is looked at, where there is one

What else we do in Thorley
Local roofs in Thorley
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. Whichever you have, the details that tend to fail before the covering itself get the closest look. Much Hadham Palace, about 2.9 miles west, is one of the historic houses in the wider area around Thorley. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and a listed home or one in a conservation area may need consent for changes of material.
Landlords with a home close to Bishops Stortford station may find that the gap between tenancies is a good time to have the roof looked at. Anyone responsible for a site like Richard Whittington Primary School will know that large buildings have long gutter runs and big roofs that need checking like any other.
Thorley is about 1 mile south-west of Bishop's Stortford, in Hertfordshire. Whether the building in Thorley is a house, a flat or a commercial unit, the roof can be surveyed. Our Hertfordshire coverage includes Thorley and the places around it. For surveys nearby, see our Chelmsford page.

Tips from our surveys
You do not need to be a roofer to help. What helps most:
- File photos of the stacks with your home records
- Ask about consent before removing a chimney on an older property
- Use a Gas Safe registered engineer for gas appliances
- Have brackets on the chimney checked
You get the report by email and can pass it to whoever does the work. Each defect is described in plain words and shown in a photo so anyone reading it can see what we saw.
Look at your chimneys from the ground now and then, especially after strong winds. Binoculars help you spot loose pots, missing mortar or lifted flashings.
Surveys for landlords and agents in Thorley
Roof problems in a rented home affect tenants as well as the building. A survey helps you spot issues early and plan the work.
Surveys can also be booked by buyers’ agents acting for a client. The report is emailed, so it can go straight to your client, photos included.
What we do, step by step
We will ask a few questions first, about the roof’s history, any leaks and past repairs. The inspection then takes about 1–2 hours at most homes; commercial roofs usually need 3–4 hours. In a small place like Thorley, access is normally the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Weekday and weekend visits are available.
- We start by noting which stacks are in use, shared or causing concern.
- The flashings and the roof around each chimney are inspected.
- We look at the flaunching and pots on every stack.
- Any lean, spalling or worn pointing is recorded.
- You receive a written report setting out what needs attention first.
Before the survey
- Have any questions written down, so nothing gets missed
- Keep pets inside or away from the areas we’re looking at
- Let us know where we can park nearby

Advice
Thorley questions
Will you come out to Thorley?
Yes, Thorley is covered. We work right across London and South East England, from towns to the smallest villages. Longer journeys are simply planned in advance.
Does a conservation area affect roof work in Thorley?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Do you inspect shared chimneys?
Yes. We check the parts we can see safely and the parts you can give us access to. If a defect seems to be on your neighbour’s side, the report records it and you can raise it with them.
Do you survey roofs on blocks of flats?
Yes, once access has been agreed. Roofs over flats are frequently shared, so the freeholder or managing agent needs to agree access. We inspect only the parts we’re allowed to reach.
Is it a structural engineer’s report?
No. We are roof surveyors, not structural engineers, and it doesn’t include calculations. We’ll recommend an engineer if we see signs that call for one.
Will you photograph what you find?
Yes. The report includes photographs of what we found, so you can see each point for yourself.
Is a chimney survey the same as a flue inspection?
No. It isn’t a flue, sweep or gas safety inspection. We look at the stack, pots, flaunching, pointing and flashings, and damp inside, and we’ll say if anything suggests the flue needs checking.
