Roof survey in Harmondsworth, Greater London
Not sure what state the roof is in? We carry out roof surveys in Harmondsworth and across Greater London, with plain-English findings.
- Condensation or damp timbers in the loft
- Loose chimney pots
- Ridge tiles that have lifted or moved
Practical tips
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Look for debris in the garden after high winds
- Include dormers, porches and garages when you book
- Stay off ladders and the roof
- Hold on to the report for future surveys
File the report with your other home documents. It’s a useful baseline for future surveys, and buyers may ask about the roof when you sell.
Have the roof surveyed every few years, and after major storms. Routine surveys pick up wear before it leaks. Each report gives a record to compare against.
Roof survey in Harmondsworth
The report is written for you, in plain language. Every issue comes with photos and a written recommendation, and we rank them by urgency where that helps. The Standard Survey adds moisture detection, a structural check and a follow-up consultation. Premium adds thermal imaging, a drone inspection where it applies and a same-day report. Each report is emailed to you. Typical surveys look at slates or tiles that have slipped or broken and lifted, split or missing lead flashings, on lead flashings, natural slate and ridges, hips and valleys.
London has Victorian and Edwardian terraces in almost every borough, many with Welsh slate roofs, shared chimney stacks and parapet or valley gutters. Slates can last a century or more, but the nails holding them corrode, and slates slip. Homes in Harmondsworth are no exception. Shared chimney stacks and the lead around them are just as important to check.
The report is yours to share with whoever needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent, whichever applies.

What else we do in Harmondsworth
Why get it checked now?
Valley gutters and parapet gutters are out of sight until they overflow. An overflow there sends water indoors. A survey checks them while they’re still dry. Behind a London parapet, a blocked gutter can sit full of water without anyone seeing it. By the time a ceiling stains, the timbers underneath may have been wet for a while.
To find out what your survey will cost, call 07833 053749 or drop us an email and let us know about the roof. The price is agreed before a date is set.

Rented homes, blocks and businesses
Any of our surveys can be booked by landlords, agents and building managers in Harmondsworth. For a price for a let property or a block, ring 07833 053749 or send us an email.
We also survey roofs for businesses and commercial landlords. Larger roofs take longer, and they’re priced for the size.
What happens on the day
Safety comes first on every visit. Everything that can safely be seen is inspected, and if part of the roof can’t be seen, the report says so. Most visits take about one to two hours for an ordinary house roof, and longer if there are extensions, dormers or several chimneys. In Harmondsworth, visits are available on weekdays and at weekends. London parking is often by permit or pay-and-display, so it’s useful to know what’s near you. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- We start with the property details and any concerns.
- We agree a date, including weekends if that suits you.
- Outside, we inspect from the ground, windows and other safe vantage points, and from the roof where safe.
- We then look in the loft for damp, staining and the condition of the underlay.
- You receive the report with photos and recommendations, prioritised by urgency.
Before the survey
- Note where any stains or damp appear
- Gather any invoices or paperwork from past roof work
- Keep pets in another room

Related advice
Different roofs, different checks
Chimney stacks
We check the stack itself, not a flue, gas or sweep inspection. If a specialist is needed, we will say so.
Clay plain and peg tiles
Where tiles hang on walls or dormers, we look at them too. Gaps in tile-hanging let water reach the wall behind.
Harmondsworth questions
Does a conservation area affect roof work in Harmondsworth?
The council and Historic England’s list are the places to check. It’s worth checking before planning roof work, as both can affect what’s allowed.
Can you fly a drone over a roof in Harmondsworth?
Typically it comes down to two things: the airspace at the address and the weather. Harmondsworth is inside, or right on the edge of, the flight restriction zone around Heathrow Airport. We ask the airport for permission before flying there, and only fly if it’s given. Across London there are restriction zones around Heathrow, London City and London Heliport, plus restricted areas over Hyde Park, the City of London and the Isle of Dogs. Every London address is checked against them before a flight. A small drone can’t fly safely in high wind or heavy rain.
Do I need to be at home?
That depends on the survey. Inside the building and in the loft, we need someone to let us in; we will agree the details when you book.
Does the weather affect the survey?
It depends on the weather and the survey. Strong wind or a downpour can make access unsafe and ground a drone, so we’d move the date with you.
Can you inspect a terraced or semi-detached roof?
Yes, the part you own or can give access to. Next door’s roof is only inspected as far as we can see it. Shared chimneys and party-wall upstands are looked at from your side.
Does a roof survey replace a structural engineer?
No. Our survey looks at the condition of the roof, and the Standard and Premium packages include a structural check. It isn’t a structural engineer’s report and does not include calculations.
Do you test for asbestos?
No. We do not carry out asbestos surveys or testing. If we see materials that could contain asbestos, such as cement sheets or soffits on older buildings, we flag them so a specialist asbestos surveyor can check before any work.
When to book a survey in Harmondsworth
Some damage starts inside the loft space. Poor ventilation lets condensation build up in the loft, wetting timbers and insulation. It is often mistaken for a leak, and it needs a different fix.
Typical things we are asked to look at include:
- Crumbling chimney pointing or cracked flaunching
- Leaking gutter joints and downpipes
- Condensation or damp timbers in the loft
- Loose ridge or hip tiles
Anyone responsible for a site like Harmondsworth Primary School will know that a written record of a large roof helps plan work for the holidays rather than in term time.
Choosing a roof surveyor
- Are they insured for the work?
- How they’ll see the roof: from ground level, the loft, the roof or by drone
- How long they’ve been surveying roofs
- Will they check the loft as well as the outside?
Harmondsworth homes and their roofs
Listing and conservation areas can both shape what roof work is allowed on an older home. Your council and Historic England’s list will tell you where you stand, before anyone quotes for re-roofing. Harmondsworth is inside, or right on the edge of, the flight restriction zone around Heathrow Airport. Where the drone is part of the survey, we ask the airport for permission first, and only fly if it is given.
Landlords with a home close to Heathrow Terminal 5 Rail station may find that a roof report helps you deal with small faults before they turn into a call from a tenant. As a London address, Harmondsworth can be tricky for parking: a visitor permit or a nearby bay makes the day easier, as a space near the door can’t be promised.
