Pre-purchase roof survey in Northwick Park
The roof is one of the most expensive parts of a home to repair, and one of the hardest for a buyer to see. Our pre-purchase roof survey gives you a proper look at it before you are committed. We check the slates or tiles, the ridges and valleys, the flashings, the chimneys and the gutters, and the loft space where it is safe to get in. The findings come in a written report with photos. We survey clay and concrete tiles, the roof space and natural slate, and people most often book us about cracked flaunching or crumbling chimney pointing and ponding, blisters or splits on a flat roof.
Homes across London range from Victorian and Edwardian terraces to interwar semis, post-war blocks and new developments, so a property in Northwick Park might be any of these. Whether the roof is old or newly laid, the problem areas depend on how and when the building went up. Slates, hidden valley gutters, parapets and flat roofs over back additions all need checking in their own way.
We write the report in plain English, so it makes sense without any roofing background. Each point is backed by a photograph where possible.

How we price pre-purchase roof surveys
A few things affect what a survey costs:
- The roof’s overall size
- Features like valleys, chimneys, dormers and parapets
- How tall the building is and how easy the roof is to see
- If the survey needs thermal imaging or a drone
The cost of a survey depends on the roof: its size, its height, how many sections it has and how it can be reached and seen safely. Prices start from £150, including VAT.
What we need to know
Getting the details right at the start saves time. It helps to include:
- The style of property, from a terrace to a block
- How the loft is reached, if there is one
- Your postcode, so we can check access and travel
- When you need the report by
If you’re buying, it is useful to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. For any other survey, just call 07833 053749 or email us when you are ready.
Why it’s worth a survey now in Northwick Park
After exchange, any roof defect is yours to deal with. Before then, you can still ask questions, ask for work to be done or reconsider. A survey after you’ve moved in tells you the same things, but with far less room to act on them. London’s older roofs often have bitumen felt underlay or none at all, so once the slates or flashings let water past, little stops it reaching ceilings. Left alone, that means wet timbers and plaster, which is a far bigger job than the roof fault itself.

Take a look at how roof surveys are priced and what we found on two real jobs.
What you can safely check yourself
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date.
Your own check is a good start, but it is not a survey. From the ground, valleys, flashings and the backs of chimneys are often out of sight, and those are details a survey looks at closely.
Before and after the survey
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Ask the agent to make sure the loft hatch can be opened
- Mention any deadline when you contact us
- Check the lease for roof repair responsibilities
- Give your solicitor a copy of the report
It’s worth sharing the report with your solicitor so questions can go to the seller’s solicitor. It can prompt questions about past roof work and any paperwork for it.
Don’t block the vents at the eaves. Poor ventilation lets condensation build up, wetting timbers and insulation. Avoid packing insulation into the eaves so tightly that air cannot flow.
Northwick Park: your questions answered
Can you fly a drone over a roof in Northwick Park?
Normally it comes down to two things: the airspace at the address and the weather. London’s airspace includes flight restriction zones around Heathrow, London City Airport and London Heliport, and restricted areas over Hyde Park, the City of London and the Isle of Dogs. Every London address is checked against them before a flight. Every flight is checked against the Drone Safety Map first. Strong wind or a downpour also stops a small drone flying.
Does a conservation area affect roof work in Northwick Park?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. 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 this an asbestos survey?
No. Our report may flag materials that could contain asbestos, but confirming it is a job for a specialist asbestos surveyor. It may be present in buildings built or refurbished before 2000.
How soon is the report ready?
The Premium Survey has a same-day report, Standard 24 to 48 hours and Basic within 48 hours. Reports are emailed, with photos.
Does someone need to be in?
Not always. An outside-only look can be arranged beforehand, but the loft and any rooms with damp need someone to let us in.
Is your roof survey a RICS survey?
No. Our survey looks at the roof only, and it isn’t a RICS home survey. It complements one rather than replacing it.
Can you survey in bad weather?
It depends on the weather and the survey. In high wind or heavy rain, a drone cannot fly and access may not be safe, and we’d agree another day.
Buying a home or a new roof in Northwick Park
If your survey includes the drone, the flight is checked against the Drone Safety Map first. Historic houses like Headstone Manor, about 1.9 miles north-west, show how far back building in the area around Northwick Park goes. Older homes in the wider area frequently have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area.
If you live in an older home near Saint Cuthberts Church, the roof may have had decades of patch repairs, and the survey shows where they are. Landlords with a home close to Kenton station may find that a roof report gives you a clear picture before you buy or settle up with a roofer. For a London address like Northwick Park, it’s useful to know about controlled parking before the day, along with any off-street space.

Rented homes, blocks and businesses
A roof problem in a let property affects your tenants as well as the building. A survey helps you spot issues early and plan the work.
If the property is let, the agent or a tenant can let us in, at a time agreed beforehand. We survey on any day of the week, which can make access easier.
How the survey works
A survey visit follows a simple order: we hear what you’ve seen, look at the roof from every safe viewpoint, photograph what we find and make notes for the report. Most visits take between one and two hours at a typical home; commercial roofs usually need 3–4 hours. In a London conversion, the way into the loft space is often from a communal landing or the top flat. Where that’s the case, access needs agreeing with whoever controls that landing. Otherwise, the visit in Northwick Park runs like any other.
- You choose a Basic, Standard or Premium Survey to suit the home you are buying.
- A date is booked on a weekday, Saturday or Sunday.
- We inspect and photograph every part of the roof we can safely see.
- 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 the survey
- Let us know where we can park nearby
- Clear the way to the loft hatch
- Have keys ready for side gates, garages or roof access doors
