Chimney surveys for homes and businesses in Roxeth
Damp on a chimney breast can have several causes. Water may be getting in at the top through cracked flaunching or an uncapped pot, through the brickwork, or at the flashings. Moisture trapped inside a stack with no ventilation can also cause damp. We check each possibility and record what we find. That points the work in the right direction. We survey chimney breasts, shared and party-wall stacks and lead flashings, and common reasons people get in touch are staining on walls around the chimney and a stack that appears to lean.
Victorian and Edwardian terraces are found right across London, often with slate roofs, chimney stacks shared with neighbours and gutters hidden behind parapets. Slates can last a century or more, but the nails holding them corrode, and slates slip. In Roxeth, as across London, that is why a roof needs a careful look rather than a glance from the street. Lead flashings and shared chimney stacks on these houses need a close look too.
You receive the findings by email, ready to forward to whoever needs them. Turnaround is within 48 hours for Basic, 24–48 hours for Standard and same day for Premium.

Spalled bricks, where the face has flaked off, are a sign of water and frost. Any spalling is noted with photos.
Chimney pots and cowls
A loose or cracked pot can fall from height. We record their condition with photographs.
What a chimney survey looks like in Roxeth
Outer London has lots of Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. If your home in Roxeth is one of them, bay roofs, hips and later dormers each have their own details. Whichever you have, the details that tend to fail before the covering itself get the closest look. With Northolt Manor about 1.9 miles south-west, Roxeth sits in an area with a long building history. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof.
Homes near green spaces such as Northwick Park can get more leaves in their gutters in autumn, so outlets and downpipes are worth watching. For landlords with property near Sudbury Hill Harrow station, a roof report between tenancies helps plan work before a small defect becomes a tenant’s leak.
Roxeth is about 1 mile south of Harrow, in Greater London. In Roxeth, as across Greater London, every roof gets the same careful survey. Our Greater London coverage includes Roxeth and the places around it. Our London page covers surveys nearby.
All of HA2, HA1 and UB5 is covered for chimney surveys, from the main roads to the quietest streets. We offer chimney surveys to properties on Lower Road, Grange Road and Dudley Road and the roads around them. If you are just outside Roxeth, we cover South Harrow (1 mile south-west), Harrow (1 mile north), Harrow on the Hill (1 mile east), Northwick Park (1 mile north-east) and Rayners Lane (1 mile west). Larger places within reach include London (12 miles south-east), City of Westminster (9 miles south-east), Marylebone (9 miles east), Kensington (8 miles south-east), St Pancras (10 miles east) and Shoreditch (12 miles east).
What’s near Roxeth
Typical jobs here are in homes near The White Horse pub, Orley Farm School and Northwick Park. For rail, the closest station is Sudbury Hill Harrow station, roughly 0.8 miles south-east of the centre. A little further out are Clementine Churchill Hospital (0.7 miles east) and Kodak Museum (1.7 miles north). For a walk, there’s Northala Fields and Perivale Wood.
Can I check my roof myself?
A lot can be seen from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.
FAQs for Roxeth
Does a conservation area affect roof work in Roxeth?
Your council is the best source, with Historic England’s list for listed buildings. Both listing and conservation areas can limit changes of roofing material.
Is parking a problem for a survey in Roxeth?
Sometimes, yes. If Roxeth has controlled parking where you are, a visitor permit is the easiest answer.
Do you test for asbestos?
No. Asbestos surveys and sampling are not something we do. The report may flag materials that could contain asbestos on buildings built or refurbished before 2000, with a recommendation to have a specialist asbestos surveyor check before it is disturbed.
Do you survey roofs on blocks of flats?
Yes, if the freeholder or managing agent agrees access. On a shared roof we can only inspect the parts we’re allowed to reach, and the report makes that clear.
Do you carry professional indemnity insurance?
We are covered by professional indemnity and public liability insurance.
Do I have to be there for the survey?
That depends on the survey. Inside the building and in the loft, we need someone to let us in, while outside access can be discussed when booking.
Can you give me structural calculations?
No. We’re roof surveyors, not structural engineers. We’ll recommend an engineer if we see signs that call for one.
How the survey works
A survey visit follows a simple order: we listen to what’s been worrying you, inspect the roof from each safe vantage point, photograph what we find and make notes for the report. Most visits take an hour or two for most houses; commercial roofs usually need 3–4 hours. In a London area like Roxeth, the main things to sort out are parking and access: tell us about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. We then look at everything that’s safely in view from the ground, windows, the loft and, where it is safe, the roof itself.
- First we talk through the stacks, their history and any problems.
- Each stack is inspected from safe positions outside.
- We photograph and record the pots, flaunching, pointing and flashings.
- We look for damp on chimney breasts and in the loft space.
- The report, with photographs and recommendations, is emailed to you.
How to prepare
- Have keys ready for side gates, garages or roof access doors
- Dig out any old roof reports or invoices
- For flats, check roof access has been agreed

Why get it checked now?
Most people never get a proper look at their chimney stacks. Problems often go unnoticed until damp appears inside. A survey gives you a clear picture before that happens. In a London terrace or conversion, a roof defect rarely stays your problem alone: failed flashings and blocked valley gutters can send water into more than one home. Finding it early keeps the work smaller.
Price depends partly on the package: Basic from £150, Standard from £250 or Premium from £400, all with VAT included. The roof’s size, height and access matter as well.

Tips that help
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Keep the report to compare against at the next survey
- Ask for ventilated caps on redundant stacks
- Never climb onto the roof to look at a chimney
- Check your stacks from ground level after strong winds
You get the report by email and can pass it to whoever does the work. We use plain English and a photo for each defect so anyone reading it can see what we saw.
Check fixings on the stack are sound, and moved if they’re working it loose. Removing unused fixings takes strain off the brickwork.
Common roof problems in Roxeth
Flaunching is the mortar bed that holds the pots and throws water off the top. Cracked flaunching lets water in, and each winter makes it worse. Loose pots can follow.
People typically book a survey after spotting one of these:
- Flashings pulling away from the stack
- Spalled or crumbling bricks
- Worn or missing pointing
- Gaps in the mortar around the pots
If you look after a shop, office or commercial unit, for instance near St. George's Shopping Centre, knowing the roof’s condition lets you budget for work rather than pay for emergencies.
