Mapesbury Pre-Purchase Roof Survey
A roof survey before you buy a house or flat in Mapesbury, with drones and thermal imaging where they help. Get in touch for a price.
- Lead that has worked loose at a wall or chimney
- Patch repairs that may hide an ongoing problem
- Standing water on a flat extension roof
How it works
After the inspection, everything we found is written up in a report with photographs, sent to you by email. On timing, most surveys take an hour or two for most houses, while a commercial roof takes nearer three to four hours. In Mapesbury, as in much of London, lots of properties are flats or terraces without side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. Mention any building rules, key holders or managing agents as you book.
- We help you pick the package that suits the property.
- A date is booked on a weekday, Saturday or Sunday.
- We inspect and photograph every part of the roof we can safely see.
- Moisture detection, structural checks, thermal imaging or a drone are added where your package includes them.
- You receive the report, with findings prioritised by urgency, so you can raise them with the seller.
How to prepare
- Make sure pets are kept safely away
- Let us know where we can park nearby
- Tell us about any leaks, stains or damp patches you know of
How to book
A quick phone call is normally the easiest start: ring 07833 053749 or send us an email. You’ll have a price before anything is arranged.

About our pre-purchase roof survey in Mapesbury
Our packages start with the Basic Survey from £150, with the Standard Survey from £250 and the Premium Survey from £400, all with VAT included. The Standard Survey adds moisture detection and a structural check. Premium goes further, with thermal imaging, a drone where it applies and a same-day report. Pick the one that fits the property. Every package comes with a written report, photos and recommendations. We survey clay and concrete tiles, the roof space and lead flashings and valleys, and people most often book us about roof slopes that look uneven or sagging and ponding, blisters or splits on a flat roof.
London terraces and converted houses often share a roof line, chimney stacks and gutters with the house next door, with parapet walls and party-wall upstands marking where one roof ends and the next begins. For a purchase or a new roof in Mapesbury, that shapes what can be checked: only the parts we are given access to and can see safely are inspected. For a flat, the lease normally says who looks after the roof.
The report is written in plain words, so you don’t need to be a roofer to follow it. Photos show what each point refers to, with the urgent items made clear.

What we look for on each type of roof
Lead flashings and valleys
Flashings close the gaps at chimneys, walls and abutments. We check whether they’ve lifted, split or been replaced with mortar or bitumen.
Chimney stacks
A leaning stack, cracked flaunching or crumbling pointing can all need work. We note them with photos so you can ask about them.
Tips from our surveys
Getting the most from a pre-purchase roof survey starts before we arrive and carries on afterwards. Tips:
- Arrange the survey as soon as your offer is agreed
- Check we will be able to get into the roof space
- Mention any deadline when you contact us
- Ask the seller about past roof repairs
After you move in, keep the report somewhere safe. Work through the urgent items before anything else, and keep the photographs to compare against later. Premium comes with a follow-up after 12 months to see how things have changed.
Check the roof from the garden and the street after a storm. Pieces of slate or tile in the garden mean something has moved. Dealing with them early keeps water out.

DIY checks: what’s safe
The one thing to avoid is getting up close. Slates, tiles, flat roofs and rooflights can give way, and falls from height are serious. That is where a survey comes in, using safe viewpoints and a drone where it applies.
Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can be a sign of a blockage or a gutter that has dropped.
Mapesbury questions
Can parking be tricky for a visit in Mapesbury?
It rarely stops a survey, but it is worth planning. Let us know the parking rules on your street and we’ll work around them.
Is drone flying allowed in Mapesbury?
That depends on where the roof is and on the weather. 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. Each address is checked against all of them before the drone goes up. Before any flight, we check the Drone Safety Map for airspace restrictions. The flight also waits for calm, dry weather.
When should I book a pre-purchase roof survey?
The sooner after your offer is accepted, the better. You need the report before you exchange, while you can still ask questions and negotiate.
Can you survey in bad weather?
It can, depending on the survey. Drones cannot fly safely in strong wind or heavy rain, and thermal imaging works best with a dry roof, little wind and a sunny day beforehand. We will rearrange with you if the weather isn’t right.
Will the roof report help me negotiate with the seller?
Yes. You might ask for work to be done, ask questions or ask for a change to the price. The outcome is between you and the seller, so we can’t promise any saving.
Which days do you carry out surveys?
We survey on any day from Monday to Sunday, during the day. Let us know your preferred days as you book.
Is a roof survey worth having alongside a home survey?
That depends on how much you want to know about the roof. Home surveys sometimes suggest a closer look at the roof, and our survey gives you that closer look. It does not stand in for a RICS survey.
Landlord and commercial surveys in Mapesbury
For a freeholder or residents’ company, a roof report is a sound basis for a maintenance plan, putting the urgent items at the top.
Shared roofs need a little more planning: we need access agreed with whoever owns or manages the building. Let us know about it as you book and we’ll plan the visit with that in mind.
Pre-purchase roof surveys in Mapesbury: local notes
If your survey includes the drone, the flight is checked against the Drone Safety Map first. 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. For a purchase or a newly finished roof, the materials decide which details matter most.
The streets around a church such as St Michael the Archangel are frequently among the oldest in a place, and if yours is one of the older homes nearby, ask the seller about past roof repairs, because older roofs often have patched valleys, replaced slates and reset ridges. For landlords with property near Wembley Stadium station, it’s worth knowing a roof’s condition before you buy it, or before you sign off new roofing work on it. Parking in Mapesbury, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day easier.

How we price pre-purchase roof surveys
Not every roof costs the same to survey, and it comes down to:
- How big the roof is
- Any need for thermal images or a drone flight
- The type of building, from a house to a block or an office
- How many separate roofs there are, like extensions, dormers and garages
Simple, low roofs take less time to survey than tall or complicated ones, and the package matters as well. The price is always agreed first.
Helping us price your survey
To price your survey accurately, we will ask about:
- Any deadline, such as an exchange date
- The property’s address and postcode
- How the loft is reached, if there is one
- Any stains, drips or damp patches you’ve seen indoors
