New roof snagging in Dartmouth Park: what you get
A new roof is a big spend, so it’s worth having it checked before the final payment. Our new roof snagging inspection looks for faults and unfinished work on the new roof and around it. The findings go into a written report with photos to share with your roofer. We are independent of the roofer who did the job. We survey flashings and valleys, new-build homes and ridges and verges, and the problems we are asked to look at most are vents that weren’t fitted or are covered and verge tiles or slates not secured.
In London, a good many 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. If you are buying a flat or house in Dartmouth Park, or have just had new roofing work done, those junctions are often where problems start. Dormer cheeks, lead work and new flat roofs are worth checking closely, as faults there are easy to miss.
You receive the findings by email, easy to pass on to a roofer, an agent or an insurer. Basic reports come within 48 hours, Standard within 24–48 hours and Premium on the day.

How we price new roof snagging
To price your survey, we check:
- Which survey package you book
- The height of the building and how the roof can safely be seen
- Extra roofs, like extensions, dormers or garages
- House, block, shop or office
The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how safely it can be seen. Prices start from £150, including VAT.
Helping us price your survey
To price your survey accurately, we’ll ask about:
- Pictures of the roof from a safe spot, if you have them
- Access details, such as a loft hatch or a shared roof
- The kind of building and roof involved
- Where water is showing inside, if it is
Once you know what you need, call 07833 053749 or send us an email. We will suggest a package, agree the price and find a date, weekday or weekend.
What we do, step by step
There is not much for you to do on the day. Show us any stains, drips or problem areas you know about, and we will get on with the inspection. A typical survey takes roughly 1–2 hours for a typical new house roof, longer where the roof is large or complicated. In a London area like Dartmouth 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’s safe.
- First, we note any deadlines and concerns.
- The roof is inspected from the ground, vantage points and the roof where safe.
- Each detail at ridges, verges, valleys and flashings is looked at.
- We check the gutters, lower roofs and walls for debris or damage.
- You receive a report to share with your roofer.
Getting ready for the survey
- Let us know about parking before the day
- Have keys ready for side gates, garages or roof access doors
- If the roof is shared, arrange access with whoever manages the building
Getting a price
Photos help, if you have them. Take them safely from ground level or a window. To send them or to book, call 07833 053749 or send us an email.
Advice
What we look for on each type of roof
Slate roofs
Broken slates left on a new roof are a common snag. They’re photographed for the report.
Flashings
Poorly finished flashings frequently show up on new roofs. They’re recorded with photos.
Checking the roof from ground level
Your own check is a good start, but it is not a survey. You will not see flashings, valleys or the backs of chimneys properly from ground level, and those are details a survey looks at closely.
During heavy rain, look at the gutters from the ground or a window. Overflowing water can be a sign of a blockage or a gutter that has dropped.
When to book a survey in Dartmouth Park
Flashings are a common source of snags. If they’re poorly dressed or fixed, water can get in at the first heavy rain.
It is worth booking a survey if you’ve seen:
- Signs of condensation in the roof space
- Debris left in gutters or valleys
- Flashings not properly dressed or fixed
- Cracked mortar at the ridge or hips
As a London address, Dartmouth Park can be tricky for parking: a visitor permit or a nearby bay makes the day easier, as a space near the door cannot be promised.
Questions to ask before booking
- What experience they bring
- Will the report include photos?
- Which viewpoints they use to see the roof
- Whether the loft space is looked at, where there is one

What else we do in Dartmouth Park
New roof snagging around Dartmouth Park
Many homes in inner London are Victorian and Edwardian terraces, often with Welsh slate roofs. Behind many of their parapets sit butterfly roofs and valley gutters that can’t be seen from the pavement. Lead flashings, party-wall upstands and shared chimney stacks are typical of these houses, if yours is one of them. Each material has its own typical faults, which is what a buyer or the owner of a new roof needs to know about. Witanhurst, about 0.8 miles north-west, is one of the historic houses in the wider area around Dartmouth Park. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first.
Landlords with a home close to Gospel Oak station may find that it is worth knowing a roof’s condition before you buy it, or before you sign off new roofing work on it. For an older house near a landmark like Church of St Mary Brookfield, ask the seller about past roof repairs, because older roofs often have patched valleys, replaced slates and reset ridges.

FAQs for Dartmouth Park
Does a conservation area affect roof work in Dartmouth Park?
We cannot confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material.
Do you cover Dartmouth Park?
We do. Every survey there gets the same written report with photographs.
Do you carry professional indemnity insurance?
We hold professional indemnity and public liability insurance, for every survey we carry out.
Will you fly a drone over my roof?
Yes, where it is applicable. Whether we can fly on the day depends on the weather and the airspace rules. We hold a CAA Flyer ID and Operator ID.
How long will you be on site?
A visit typically takes about 1–2 hours for a typical new house roof, longer where the roof is large or complicated. We’ll give you an idea when booking.
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 when you book.
What’s the best time to have a new roof checked?
Before the final payment is best, while the roofer is still on hand. If that is passed, book before any defects or warranty period ends.
Why get it checked now?
Phone photos from the garden can’t show much. We get as close a view as safe access allows, including by drone where it is applicable. In Dartmouth Park, 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. Dealing with it early is far less disruptive.
A Basic Survey starts from £150, with VAT included. Standard is from £250 and Premium from £400, both including VAT. We confirm the price for your roof before booking.
