Pre-purchase roof survey in Harrow Weald
Older homes often have roofs that have been patched over the years. Slates slip when their nails corrode, lead valleys and flashings wear, and chimney pointing crumbles. Most of it can’t be seen from the street. We look closely and record what we see, with photographs that show you exactly where. We explain each finding in plain English, so it’s clear what it means for your purchase. If you’re worried about lead that has worked loose at a wall or chimney and gutters choked with leaves and moss, we can find out what’s behind it, on chimney stacks, flat-roofed extensions and dormers and clay and concrete tiles alike.
In a London terrace or conversion, the roof often joins the neighbours’ roofs and shares their stacks and gutters, with parapet walls and party-wall upstands marking where one roof ends and the next begins. For a purchase or a new roof in Harrow Weald, that shapes what can be checked: only the parts we’re given access to and can see safely are inspected. For a flat, the lease typically says who looks after the roof.
Where we cannot see part of the roof, the report says so. You will know exactly what was inspected and what wasn’t, and what we’d suggest next.

Rented homes, blocks and businesses
A roof problem in a let property affects your tenants as well as the building. A survey shows what needs attention, so you can plan the work.
Freeholders and residents’ companies use a roof report to plan and budget, with the most urgent items set out first.
How the survey works
There isn’t much for you to do on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we’ll get on with the inspection. The survey itself takes about one to two hours at the house you’re buying, depending on its size and how much of the roof can be seen. For a visit in Harrow Weald, parking and access are the things to plan: let us know about parking, the floor the property is on, any shared entrance and loft access. On the day, the roof is looked at from the ground, from windows, from inside the roof space and from the roof where it’s safe.
- We help you pick the package that suits the property.
- We agree a visit, including weekends if that helps.
- The coverings, ridges, valleys, flashings, chimneys and gutters are inspected and photographed.
- Standard and Premium surveys add the extra checks they include.
- You receive the report, with findings prioritised by urgency, so you can raise them with the seller.
Before we arrive
- Agree roof access with the managing agent if it is shared
- Find any records of previous roof work
- If it is not your property yet, arrange access through the agent
Arrange a survey
Buyers should book once an offer has been accepted, so there is time to use the report before exchange. For any other survey, just phone 07833 053749 or use the contact form when you are ready.

FAQs for Harrow Weald
How do I find out if my home in Harrow Weald is listed?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Is parking a problem for a survey in Harrow Weald?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when booking.
Do you need to go inside the property?
Where we can, yes. Inside, the loft shows leaks, damp timbers and the underlay. If access is not possible, we note it in the report.
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 frequently shared, so the building owner or managing agent needs to agree access. We inspect only the parts we’re allowed to reach.
Is Harrow Weald in your area?
Yes. We survey roofs across London and South East England, and that includes Harrow Weald.
Is this an asbestos survey?
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’s disturbed.
How many surveys have you done?
We have completed more than 5,000 surveys, across 20+ years of surveying roofs, with 98% customer satisfaction.
What affects the price in Harrow Weald
A few things affect what a survey costs:
- The use of thermal imaging or a drone
- How tall the building is and how easy the roof is to see
- Whether you choose the Basic, Standard or Premium Survey
- Features like valleys, chimneys, dormers and parapets
The Premium Survey includes thermal imaging and drone inspection where applicable, which starts from £400, including VAT. We can help you choose the package that fits what you need to know.
Booking your survey
Some details help us recommend the right survey and price. When you get in touch, it helps to mention:
- Your postcode, so we can check access and travel
- Access details, such as a loft hatch or a shared roof
- Dates you are working to, like exchange
- Where any leaks, stains or damp patches show inside
Surveys can be booked for weekdays, Saturdays or Sundays. To find a date that works for you, ring 07833 053749 or use the contact form with the address and the days you’d prefer.
When to book a survey in Harrow Weald
Asbestos was banned in UK construction in 1999. It’s often found in cement sheets, soffits and flue pipes. We do not carry out asbestos surveys, but our report flags materials that could contain it and suggest a specialist asbestos surveyor checks them before work starts.
People typically book a survey after spotting one of these:
- Worn or lifted lead flashings
- Loose pots and cracked flaunching
- Bitumen or mortar used in place of proper repairs
- Roof slopes that look uneven or sagging
With Headstone Manor about 0.9 miles south-west, the area around Harrow Weald has a long history. When you buy an older home, the roof’s age, past repairs and any listing all affect what you might spend later.
Choosing a roof surveyor
- Whether any drone flown is registered with the CAA
- What exactly goes into their report
- How long the report takes to arrive
- Will they check the loft as well as the outside?
What we look for on each type of roof
Chimney stacks
A stack stands exposed above the roof line. The pots, flaunching, pointing and flashings are all checked, as far as we can see them safely.
Natural slate
Older slate roofs often have bitumen felt under them, and very old ones may have none. Where we can see it from the loft, we say what condition it is in.
Buying a home or a new roof in Harrow Weald
In outer London, interwar semis with hipped, tiled roofs sit alongside older slate-roofed terraces. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Material and age explain a lot of what turns up on the day, whether the roof is old or brand new. Where the drone is part of the survey, the flight is checked against the Drone Safety Map first.
As a London address, Harrow Weald can be tricky for parking: a visitor permit or a nearby bay makes the day easier. If you let a flat or house near Headstone Lane station, a written report helps before buying a rental or paying for a new roof on one.
