Chimney survey in Langley, Hertfordshire
A survey of chimney stacks, pots, flashings and flaunching in Langley, carried out by an experienced roof surveyor. You get a clear written report with photographs.
- Spalled or crumbling bricks
- Signs that a stack is leaning
- Eroded joints in the brickwork
Before and after the survey
Most of what helps is simple and safe from ground level. Our suggestions:
- Check your stacks from ground level after strong winds
- Ask about consent before removing a chimney on an older property
- Have brackets on the chimney checked
- Keep the report to compare against at the next survey
If the report recommends a structural engineer, a sweep or a Gas Safe registered engineer, it will say why. It gives them a clear starting point.
Check redundant flues are capped with ventilation. That helps stop damp building up inside.
Chimney survey in Langley: what you get
Redundant chimneys are common, especially where fires have been replaced by central heating. Even when it is not used, a stack has to stay weathertight. If it has been capped without ventilation, damp can build up inside it. We check how redundant stacks have been capped and look for damp in the chimney breasts. The report sets out what we found and what we recommend. If you’re worried about mortar washing out of the joints and lifted or split lead flashings, we can find out what’s behind it, whatever the roof.
In a small place like Langley, many roofs stand in the open, which is hard on ridges, chimneys, flashings and gutters. Older walls take a long time to dry once water gets in. A roof report shows what needs attention first. On exposed older roofs, chimneys and lead flashings are often the first to give way.
We keep jargon out of it: where something needs attention, it says so plainly.

Langley: your questions answered
Will you come out to Langley?
We do. A small place gets exactly the same survey as a big one.
How do I find out if my home in Langley is listed?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Does someone need to be in?
Not always. An outside-only look can be arranged beforehand, but anything inside needs someone there to give access.
Will you walk on the roof?
Not unless it is safe. Most of what we need can be seen from safe viewpoints, the loft and, where it applies, a drone, and anything out of sight is recorded in the report.
Should a redundant chimney be removed?
There’s no single answer. We record how the stack is doing and whether it’s capped with ventilation. In a conservation area or on a listed building, changes may need consent.
Do you need to go on the roof to check the chimney?
We inspect from wherever is safe: from the ground, windows and vantage points, and from the loft where there’s access. A drone inspection is included in our Premium Survey where it applies. We note anything we couldn’t see.
Will you fly a drone over my roof?
Where it’s applicable and safe, yes. We’re a CAA-registered drone operator (Flyer ID and Operator ID), flying a sub-250g drone. It’s included in the Drone Roof Survey and, where it applies, the Premium Survey.
Local roofs in Langley
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. Each of these coverings has its own weak points, from fixings and valleys to flashings, chimneys and gutters. With Knebworth House about 1.3 miles south-east, Langley sits in an area with a long building history. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area.
Take a building like The Thomas Alleyne School: long gutter runs and wide roofs on a building that size are worth checking on a regular cycle.

Do you need a chimney survey in Langley?
Stacks that were used for open fires for many years can weaken from the inside. Mortar can deteriorate unevenly from flue gases and moisture, which is one reason stacks start to lean.
Things that often lead to a survey include:
- Signs that a stack is leaning
- Unused flues sealed without airflow
- Bricks with flaking faces
- Damp on a chimney breast inside
Landlords with a home close to Stevenage station may find that a roof report helps you deal with small faults before they turn into a call from a tenant.
Before booking any roof surveyor
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- Whether the price includes VAT
- Which limits apply to the survey
- What follow-up you get after the report
How it works
Before we start, let us know why you’ve booked: buying, a leak, storm damage, new work or just wanting to know where things stand. That way we can focus on what matters to you. The visit typically takes about one to two hours at a house, as part of a look at the roof around the stack. For a village or hamlet like Langley, the journey is planned beforehand: tell us about narrow lanes, gates, long drives and where we can park. The roof is looked at from ground level, from windows, from the loft where there is safe access and from the roof where it’s safe.
- You let us know whether any stacks are shared, unused or leaning.
- The flashings and the roof around each chimney are inspected.
- We check the flaunching and pots on every stack.
- We note the brickwork, pointing and any sign of leaning.
- You receive a written report setting out what needs attention first.
Before the survey
- Agree roof access with the managing agent if it is shared
- Unlock side gates and any roof access doors
- Let us know about parking before the day
Getting a price
We survey roofs on weekdays, Saturdays and Sundays. To find a date that works for you, phone 07833 053749 or drop us an email.
Advice
Should I look at the roof myself first?
After strong wind, take a look from the pavement or garden: 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.
The one thing to avoid is getting up close. Roofs are fragile and slippery, and falls from height are serious. That part is for a survey.
How the survey changes by roof type
Chimney breasts and the loft
Where a breast has been taken out, we check what supports the stack. Confirming the support is a job for a structural engineer.
Lead flashings
Lead flashings seal the joint between the stack and the roof. The survey looks at whether the lead is tight, sound and well fixed.
