Pre-purchase roof surveys for homes and businesses in North Harrow
We survey roofs for buyers in North Harrow and across London and the South East. From terraced and semi-detached homes to detached houses and flats, we follow the same careful process. The report says what’s in good order, what isn’t and what to deal with first. We hold professional indemnity and public liability insurance, and have 20+ years’ experience. To book, ring 07833 053749 or drop us an email. We survey clay and concrete tiles, the roof space and gutters and downpipes, and common reasons people get in touch are gutters choked with leaves and moss and worn or lifted lead flashings.
In London, lots of houses have been split into flats, extended or fitted with a dormer loft conversion. Each change adds roof details, such as flat roofs, new flashings and junctions with the original slopes. For a purchase in North Harrow, 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 Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey goes further, with thermal imaging, drone inspection where applicable, structural analysis and an in-person consultation.

What affects the price in North Harrow
Several things affect the price of a survey:
- How many separate roofs there are, like extensions, dormers and garages
- How tall the building is and how easy the roof is to see
- The type of building, from a house to a block or an office
- The use of thermal imaging or a drone
There are three survey packages: Basic from £150, Standard from £250 and Premium from £400, all with VAT included. The price for your roof depends on its size, access and what you want to find out.
What we need to know
A little information up front helps. Please include:
- Photos of the roof, taken safely from ground level or a window
- What’s prompted the survey
- Where the property is, with the postcode
- The type of building and roof, such as pitched or flat
Most bookings start with a short call: phone 07833 053749 or use the contact form and we’ll ask a few questions about the roof. The price is agreed before a date is set.
For landlords and managing agents
We also survey roofs for businesses and commercial landlords, from shops and offices to industrial units. Bigger roofs take more time, so they’re priced to suit.
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. The report sets out what needs attention now and what can wait, which helps when budgeting.
How it works
The visit has one job: to look at the roof as closely as is safe and record what we find. Notes and photographs go into the written report. The visit typically takes roughly 1–2 hours on an ordinary house, with bigger or more complicated roofs taking longer. In converted houses and mansion blocks, the loft hatch is often on a shared landing. If that applies to your building, it’s useful to agree access with the neighbours or the managing agent first. Everything else is planned around the building, not the postcode.
- We help you pick the package that suits the property.
- We agree a visit, including weekends if that helps.
- 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.
Preparing for the visit
- If you are buying, check with the agent that we can get in
- Keep pets in another room
- Leave side gates unlocked

What a pre-purchase roof survey looks like in North Harrow
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. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. The covering on a house you are buying, or on a roof just finished, tells us where to look hardest. If your survey includes the drone, the flight is checked against the Drone Safety Map first.
For a London address like North Harrow, it’s useful to know about controlled parking before the day, along with any off-street space. Landlords with a home close to Harrow-on-the-Hill station may find that a survey before purchase, or before signing off a new roof, saves surprises once a tenant moves in. If you live in an older home near Church of St Alban, the roof’s history matters as much as its looks, and a survey brings the past repairs to light.

What this survey cannot tell you
Every survey has limits, and we’d rather be clear about that before booking. Keep these in mind:

- What’s under the slates, tiles or felt
- Anything beyond the roof, which a full home survey covers

FAQs for North Harrow
Will parking be an issue for a roof survey in North Harrow?
London parking needs a little planning, so let us know about permits, bays or a driveway when booking. The visit is then planned around what’s available.
Is my home in North Harrow listed or in a conservation area?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
How long will you be at the property?
On site, it normally takes between one and two hours at a typical house, with time for the loft where it can be reached. The report follows within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium.
Do you cover North Harrow for pre-purchase roof surveys?
Yes, we do. North Harrow is part of the area we cover.
Do you need access inside the house?
If it can be arranged, yes. From the roof space we can see staining, timbers and underlay. If we can’t get in, the report says so.
Will the roof report help me negotiate with the seller?
Yes. You’ll have photos and a written description of each defect, which you can share with the seller or agent. We cannot promise how the seller will respond.
Do you carry professional indemnity insurance?
We’re covered by professional indemnity and public liability insurance, for every survey we carry out.
Can I check my roof myself?
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
Your own check is a good start, but it isn’t 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.
Leave it or get it looked at?
Without a survey, you’re relying on a glance from the pavement. That rarely shows the back slope, the valleys or the top of the chimney. We fill that gap before you are tied in. In North Harrow, as in much of London, water from a roof defect can reach a neighbour’s home as easily as yours: failed flashings and blocked valley gutters can send water into more than one home. Finding it early keeps the work smaller.
A Basic Survey starts from £150, with VAT included. The Standard Survey starts from £250 and the Premium Survey from £400. We confirm the price for your survey before booking.
