Canons Park Pre-Purchase Roof Survey
A roof survey before you buy a house or flat across Canons Park, using drones and thermal imaging where it applies. Call or email for a price.
- Gaps where slates or tiles have come loose
- Signs of past leaks inside the loft
- Sagging ridge lines or uneven roof slopes
Rented homes, blocks and businesses
Managing agents and residents’ management companies use roof surveys to plan maintenance. Recommendations are set out in order of urgency where relevant, which helps when budgeting.
Businesses and commercial landlords can book us too. Bigger roofs take more time.
Pre-purchase roof surveys for homes and businesses in Canons Park
The best time to book is once your offer has been accepted and before you exchange contracts. At that point you can still ask questions, because nothing is binding yet. Visits run on weekdays and at weekends, which helps when a sale is moving quickly. The report comes within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium. We survey natural slate, gutters and downpipes and lead flashings and valleys, and the problems we are asked to look at most are gutters choked with leaves and moss and quick fixes on flashings and valleys.
In London, plenty of houses have been split into flats, extended or fitted with a dormer loft conversion. Each change adds roof details, like flat roofs, new flashings and junctions with the original slopes. For a purchase in Canons Park, or for new roofing work there, those junctions deserve a proper look. Lead work around dormers and new flat roofs is easy to get wrong and easy to miss.
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.

Why it is worth a survey now in Canons Park
A slow leak can go unnoticed for months. Damp can spread into timbers and ceilings before anyone sees a mark. Finding the cause at the survey stage means you know about it from day one. 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.
A Basic Survey starts from £150, inc. VAT. Standard is from £250 and Premium from £400. You’ll know the price for your roof before booking.
What you get with us

When to book a survey in Canons Park
Patch repairs are common on roofs of every age. Bitumen over flashings, mortar fillets in place of lead and odd replacement tiles can point to a problem that keeps coming back. We note what we see so you can ask about it.
Look out for signs like these:
- A ridge or slope that dips
- Slipped or missing slates and tiles
- Old water stains in the loft space
- Worn or lifted lead flashings
The streets around a church like Church of St Lawrence are often among the oldest in a place, and if you own one of the older houses nearby, older patch repairs can hide behind a tidy front slope, and the survey looks past them.
What to check before booking
- What happens after the report arrives
- How much experience they have with roofs like yours
- Will they check the loft as well as the outside?
- What the survey will not cover
What happens on the day
Every visit follows the same pattern: we hear what you’ve seen, look at the roof from every safe viewpoint, photograph what we find and record our findings for the written report. Most visits take about 1–2 hours at a typical house, with time for the loft where it can be reached. In a London area like Canons Park, the main things to sort out are parking and access: let us know about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. On the day, the roof is looked at from ground level, from windows, from inside the roof space and from the roof where it is safe.
- Once your offer is accepted, you let us know the address and when you hope to exchange.
- Access to the house and the roof space is agreed in advance.
- We start outside, looking at the roof from ground level and from vantage points.
- We then look from upstairs windows and inside the loft where it’s safe.
- The report is emailed with photos and recommendations, ready to use before exchange.
Preparing for the visit
- Find any records of previous roof work
- Have any questions written down, so nothing gets missed
- Show us where any leaks or stains appear

What else we do in Canons Park
Buying a home or a new roof in Canons Park
Outer London has a good many Victorian and Edwardian terraces with slate roofs, but also a great many interwar semis, often with hipped roofs in clay or concrete tiles. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Material and age explain a lot of what turns up on the day, whether the roof is old or brand new. Historic houses like Headstone Manor, about 3 miles west, show how far back building in the area around Canons Park goes. Older homes in the wider area often 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 own a rental within reach of Mill Hill Broadway station, a roof report gives you a clear picture before you buy or settle up with a roofer. Controlled parking zones are common in London, so mention any permit rules for Canons Park, along with any off-street space.

What’s near Canons Park
Locally, jobs take us to homes and businesses close to Edgwarebury Park, Railway Hotel and Krishna Avanti Primary School and the streets around them. The closest station to Canons Park is Mill Hill Broadway station, roughly 1.7 miles east of the centre. A little further out are Hilfield Castle (3.7 miles north-west) and Broadwalk Centre (0.6 miles east). Green spaces nearby include Edgware Way Grassland and Darland's Lake.
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.
Look up at the roof after a storm, from the ground: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Leave anything above ground level to a survey.
Common questions in Canons Park
Can parking be tricky for a visit in Canons Park?
It rarely stops a survey, but it is worth planning. Tell us what parking is available nearby, and the visit is planned around it.
Can you fly a drone over a roof in Canons Park?
The answer turns on the exact location and the conditions on the day. 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. Each address is checked against all of them before the drone goes up. Every flight is checked against the Drone Safety Map first. Strong wind or a downpour also stops a small drone flying.
What if it rains on the day?
Light rain is typically fine; heavy rain and wind are different. Strong wind or a downpour can make access unsafe and ground a drone, and we’d agree another day.
How long does a pre-purchase roof survey take?
It usually takes about one to two hours at a typical home, though large, tall or awkward roofs take more time. Report times depend on the package, from the same day for Premium to within 48 hours for Basic.
Do I need to be at home?
Not necessarily. An outside-only look can be arranged beforehand, but anything inside needs someone there to give access.
Can you tell me if my roof has asbestos?
No. We don’t sample or test for asbestos. Where a material might contain it, like old cement sheets on a building from before 2000, the report flags it.
How many surveys have you done?
More than 5,000 surveys over 20+ years.
Tips that help
A survey works best with a little help from you, before and after. Tips:
- Look for fresh paint on upstairs ceilings at viewings
- Pass the findings to your conveyancer
- Ask whether there are papers for past roof work
- For a flat, check who is responsible for the roof
Once the home is yours, the report becomes a maintenance list. Work through the urgent items before anything else, and keep the photos to compare against later. The Premium Survey includes a 12-month follow-up.
After strong winds, look at the roof from the ground. Slipped slates, lifted ridge tiles and debris on the ground are signs to act on. Dealing with them early keeps water out.
