New roof snagging for homes and businesses in Harrow on the Hill
We check the coverings, ridges, verges, hips and valleys, along with the flashings and ventilation. At the eaves we look at how the underlay is dressed into the gutter, where it can be seen, and we look at the gutters too. You get a photo report of what we found. We also note debris left behind and any damage to other parts of the building. We survey new flat roofs, replacement roofs and loft conversions and dormers, and the problems we’re asked to look at most are signs of condensation in the roof space and cracked or slipped new tiles or slates.
London’s housing runs from Victorian and Edwardian terraces to interwar semis, post-war estates and new blocks of flats, so a property in Harrow on the Hill might be any of these. Whether you’re buying or have just had a roof replaced, the details that cause trouble depend on the age of the building. Slates, hidden valley gutters, parapets and flat roofs over back additions all need checking in their own way.
You can share the report with anyone who needs it: your solicitor, the seller, your insurer, a roofer or the building’s managing agent.

What affects the cost of new roof snagging
Prices always include VAT. What changes the price is:
- The height of the building and how the roof can be seen safely
- Any need for thermal images or a drone flight
- Whether it’s a home or a commercial building
- The package you choose: Basic, Standard or Premium
We offer three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, with VAT included. What your roof costs depends on its size, access and what you want to find out.
Helping us price your survey
The more you let us know, the easier it is to price the survey. When you contact us, it is useful to mention:
- Anything about access we should know
- The address and postcode of the property
- Where any leaks, stains or damp patches show inside
- The kind of building and roof involved
We survey roofs on any day of the week. To arrange a day that suits you, phone 07833 053749 or send us an email with the address and the days you’d prefer.
How it works
Expect us to ask a few questions before we start, such as when any problem began and what work has been done before. The inspection then takes an hour or two at a typical home, and more on a big or complicated roof. In Harrow on the Hill, as in much of London, a good many properties are flats or terraces without side access, so the back of the roof is frequently seen from upstairs windows, from inside or, where a flight is allowed, from the air. Mention any building rules, key holders or managing agents when booking.
- First, we note any deadlines and concerns.
- We inspect as far as safe access allows.
- We work through ridges, verges, valleys and flashings.
- Debris and damage to other parts are recorded.
- You receive a report to share with your roofer.
Before the survey
- Let us know about parking before the day
- Leave side gates unlocked
- Keep pets out of the way during the survey
Book a survey
If you are buying, it helps 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 phone 07833 053749 or send us an email when you’re ready.

Harrow on the Hill questions
Will parking be an issue for a roof survey in Harrow on the Hill?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
Do you carry out roof surveys in Harrow on the Hill?
Yes, Harrow on the Hill is one of the places we work. The survey and report are the same in Harrow on the Hill as anywhere else.
Is snagging available for a new-build house roof?
Yes, new-build roofs are checked in the same way as replacement roofs. You get a photo report of any snags for you to pass to your builder.
Can you survey at the weekend?
We survey on any day from Monday to Sunday, during the day. Let us know your preferred days when you book.
Do you test for asbestos?
No. We do not sample or test for asbestos. 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 is disturbed.
How many surveys have you done?
Over 5,000 surveys so far, over more than 20 years.
Will you walk on the roof?
Only when it’s safe. Safe viewpoints, the roof space and a drone where it applies cover most of what’s needed, and anything out of sight is recorded in the report.
Practical tips
These tips come from what we see on roofs every week:
- Raise snags in writing with your roofer
- Let your roofer know an inspection is planned
- Watch for drips in the loft space with care
- Book snagging before the final payment
You receive a photo-illustrated written report of each snag and recommendations, prioritised by urgency where relevant. Pass it on to your roofer or builder.
File the contract, invoices and warranty papers in one place. The report belongs with them.
Should I look at the roof myself first?
What you can’t do safely is get up close. Slates, tiles, flat roofs and rooflights can give way. That’s 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. Overflowing water can be a sign of a blockage or a gutter that has dropped.
Why it’s worth a survey now in Harrow on the Hill
Some faults only show when water gets in. Checking early gives you a record of the roof’s condition at handover. London’s older roofs often have bitumen felt underlay or none at all, so a slipped slate can soon mean water inside. Left unchecked, water soaks into timber and plaster and the damage spreads.
Our price is from £150, including VAT. The final price depends on the size and height of the roof, access and the package you choose.

What we cannot see

- How the roof will perform for years to come
- Legal advice on your contract
- What’s under the new coverings

What new roof snagging looks like in Harrow on the Hill
With Northolt Manor about 2.1 miles south-west, Harrow on the Hill sits in an area with a long building history. If your house is among the older ones, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. For a purchase or a newly finished roof, the materials decide which details matter most.
For landlords with property near Sudbury Hill Harrow station, a written report helps before buying a rental or paying for a new roof on one. For an older house near a landmark such as Christ Church, the roof may have had decades of patch repairs, and the survey shows where they are. As a London address, Harrow on the Hill can be tricky for parking: a visitor permit or a nearby bay makes the day easier, as a space near the door can’t be promised.
