Harrow on the Hill Chimney Survey
A careful look at the chimney stack at your property in Harrow on the Hill, and put it all in a report with photographs.
- Damaged chimney pots and cowls
- Unused flues sealed without airflow
- Cracked or missing flaunching
About our chimney survey in Harrow on the Hill
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. Our survey checks each of these and records the likely cause. That points the work in the right direction. If you’ve noticed staining on walls around the chimney and pots or cowls that look unsafe, a survey will tell you what’s going on, whatever the roof.
Much of London’s housing is flats, in converted houses or purpose-built blocks, where the roof is usually a shared part of the building. Landlords, managing agents and residents’ companies need to know what condition it’s in and what work is coming up. Leaks from a shared roof rarely affect just one home. A report gives everyone the same picture to plan from, with photos.
We write the report in plain English, so it makes sense without any roofing background. Photographs show what each point refers to, with the urgent items made clear.

Your questions about chimney surveys in Harrow on the Hill
I let a flat near Sudbury Hill Harrow station. Can you check the roof?
Yes. We survey roofs for landlords, letting agents and managing agents as well as owners. You can ring 07833 053749 or email us with the address and what you need.
How do I find out if my home in Harrow on the Hill is listed?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Does someone need to be in?
It depends on what we need to see. For inside areas and the loft space, someone has to give us access.
Is it the same as a RICS Level 2 or Level 3 survey?
No. We’re experienced roof surveyors, and our survey covers the roof rather than the whole building. For the rest of the building, a RICS home survey is a separate job.
How long will you be at the property?
Time on site depends on the roof, but most surveys take about 1–2 hours for most homes, a little longer where there are several stacks. The written report follows by email.
What do you check on a chimney?
Every part of the stack we can see from safe positions: pots, cowls, flaunching, pointing, bricks and flashings. We also note leaning, redundant stacks and damp inside.
Will you photograph what you find?
Yes, plenty. Pictures sit next to the findings they show, which makes the report easy to follow.

Chimney surveys in Harrow on the Hill: local notes
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Whichever you have, the details that tend to fail before the covering itself get the closest look. About 2.1 miles south-west lies Northolt Manor, a reminder of how long the area around Harrow on the Hill has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs.
For an older house near a landmark such as Christ Church, its roof may have old fixings, lead flashings and chimneys that need a closer look. Landlords with a home close to Sudbury Hill Harrow station may find that the gap between tenancies is a good time to have the roof looked at.

The survey, step by step
We don’t take risks to get a closer look. We inspect whatever is safely visible, and anything we can’t see is noted in the report. Most visits take about 1–2 hours for a house, while a commercial roof takes nearer three to four hours. In converted houses and mansion blocks, the loft hatch is frequently on a shared landing. Where that is the case, access needs agreeing with whoever controls that landing. Otherwise, the visit in Harrow on the Hill runs like any other.
- We go through the chimneys, any damp and any work done on them.
- We look at every stack from wherever it can be seen safely.
- Pots, cowls, flaunching, pointing and flashings are checked and photographed.
- Inside, the chimney breasts and the loft are checked for damp where there’s access.
- You get a written report with photos and recommendations by email.
How to prepare
- Gather any invoices or paperwork from past roof work
- Check the loft hatch can be reached
- Make sure we can get to the back of the property

Tips from our surveys
You don’t need to be a roofer to help. What helps most:
- 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
- Never climb onto the roof to look at a chimney
After the visit, we write up the report with photographs of each stack. It covers the pots, flaunching, pointing, brickwork and flashings, and any damp we found inside. Basic reports arrive within 48 hours, Standard reports in 24 to 48 hours and Premium reports the same day.
Look at your chimneys from ground level now and then, particularly after strong winds. With binoculars, you can often see cracked flaunching or lifted lead.
Roof by roof
Chimney breasts and the loft
Inside, chimney breasts can show damp when water gets into the stack. We check the breasts and the stack in the loft space where we can reach.
Flaunching
Cracked flaunching is one of the most common chimney defects we record. Caught early, it is often a small job.
Leave it or get it looked at?
If you’re buying, find out about the stacks before you exchange. Once you’ve exchanged, the work is down to you. A report gives you something specific to put to the seller. Behind a London parapet, a blocked gutter can sit full of water without anyone seeing it. When the stain finally shows, the damage underneath is often older than it looks.
The Premium Survey includes thermal imaging and drone inspection where applicable, which starts from £400, with VAT included. We will tell you which package suits the questions you have.

Common roof problems in Harrow on the Hill
Flashings seal the gap where a stack passes through the roof. With age they can lift, split or come away from the joints. When flashings fail, water often shows up in the loft or on the chimney breast. Lead is also a target for theft.
Typical things we’re asked to look at include:
- Unused flues sealed without airflow
- Eroded joints in the brickwork
- Lifted or split lead flashings
- Damp patches on chimney breasts
Anyone responsible for a site like St George’s Primary Catholic Voluntary Academy will know that long gutter runs and wide roofs on a building that size are worth checking on a regular cycle.
Questions to ask before you book
