How the survey changes by roof type
Flaunching
The sloping mortar around the pots is called flaunching. Once it cracks, water can get straight into the brickwork.
Lead flashings
Where the chimney meets the roof slopes, lead flashings keep water out. The survey looks at whether the lead is tight, sound and well fixed.
How a chimney survey works in College Park
Redundant chimneys are common, especially where fires have been replaced by central heating.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. Capping a stack without ventilation can trap moisture and lead to damp inside. 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. Common reasons to book are redundant stacks capped without ventilation and damp on a chimney breast inside, across lead flashings, chimney breasts and chimney pots and cowls.
Much of London’s housing is flats, in converted houses or purpose-built blocks, where the roof is normally a shared part of the building. Whoever looks after the building needs a clear picture of the roof, chimneys and gutters. A defect on a shared roof can reach more than one flat. With a written report and photographs, everyone can plan from the same facts.
The report is written in plain words, so it makes sense without any roofing background. Each point is backed by a photograph where possible, and recommendations are put with the most urgent first where relevant.

The survey, step by step
Expect us to ask a few questions before we start, about the roof’s history, any leaks and past repairs. The inspection then takes about 1–2 hours at a typical home; commercial roofs usually need 3–4 hours. Many London properties are flats or terraces with no side access, so the back of the roof is often seen from upstairs windows, from inside or, where a flight is allowed, from the air. Mention any building rules, key holders or managing agents when you book.
- We start by noting which stacks are in use, shared or causing concern.
- We check the roof around each stack, including the flashings.
- 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.
Preparing for the visit
- Leave a clear route to the loft
- Have any paperwork from past roof work to hand
- Leave side gates unlocked
How to book
Chimney survey starts from £150, including VAT. The exact figure depends on the roof and the package, and you can ring 07833 053749 or send us an email to find out.
Advice
College Park homes and their roofs
Inner London’s Victorian and Edwardian terraces often have Welsh slate roofs. Behind many of their parapets sit butterfly roofs and valley gutters that cannot be seen from the pavement. If your home in College Park is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. Whichever you have, the details that tend to fail before the covering itself get the closest look. Leighton House, about 2.6 miles south-east, is one of the historic houses in the wider area around College Park. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material.
Anyone responsible for a site like Kenmont Primary School will know that its roofs, gutters and any chimneys need the same checks as a house’s, just on a bigger scale. If you look after a shop, office or commercial unit, for example near Westfield London, knowing the roof’s condition lets you budget for work rather than pay for emergencies.

Landlords, agents and block managers in College Park
If the property is let, the agent or a tenant can let us in, at a time agreed beforehand. Surveys run on any day of the week, which can make access easier.
If you own several properties, you can book surveys for several addresses. To discuss a number of properties, ring 07833 053749 or use the contact form with the addresses.
What you can safely check yourself
During heavy rain, look at the gutters from the ground or a window. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
Look up at the roof after a storm, from ground level: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Don’t go up yourself.
What happens if roof problems are left?
A small amount of repointing or new flaunching is usually a modest job. Left for a few winters, frost and water can loosen pots and bricks and the job gets bigger. 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 cost of a survey depends on the roof: its size, its height, how many sections it has and how safely it can be seen. Our price is from £150, including VAT.

College Park questions
Does a conservation area affect roof work in College Park?
We can’t confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material.
Can a landlord with a rental near Willesden Junction station book a roof survey?
Yes, landlords and agents are among the people we work for. You can phone 07833 053749 or send us an email with the address and what you need, and we’ll talk through which survey suits.
What should I do with a chimney I do not use?
There is no single answer. The survey shows its condition and how it’s been capped. In a conservation area or on a listed building, changes may need consent.
How do I book a survey in College Park?
To book, phone 07833 053749 or email us and tell us the address and what you’d like to know. We will confirm the price and find a day that suits.
How long have you been surveying roofs?
Over 20 years and more than 5,000 surveys.
Do you need to get into the loft?
If it’s needed and safe to reach, yes. Inside, we look for damp, staining, gaps and sagging, as far as the space allows.
I live in a flat. Can you survey the roof?
Yes, once access has been agreed. The roof of a block or converted house is often shared, so we need permission from whoever owns or manages the building. We inspect only the parts we are allowed to reach.
Do you need a chimney survey in College Park?
Removing a chimney breast inside can leave questions about how the stack is supported. We record what we can see in the loft and outside, and the report recommends a structural engineer if support is a concern.
People normally book a survey when they’ve noticed one of these:
- Worn or missing pointing
- Damaged chimney pots and cowls
- Flaunching that has broken away
- Signs that a stack is leaning
If you own a rental within reach of Willesden Junction station, a roof report between tenancies helps plan work before a small defect becomes a tenant’s leak.
What to check before booking
- Whether the roof space is looked at, where there is one
