About our new roof snagging in City of Westminster
A snag is a fault or unfinished detail left when work is done. Roof snags often show at ridges, verges, valleys and flashings, where the detailing is hardest. We check everything we can see safely and record what we find. Loose ridges, untidy verges, badly dressed flashings and leftover debris are typical snags. We’re frequently asked to look into flashings not properly dressed or fixed and cracked lower roofs or marked walls after the work, across replacement roofs, new-build homes and flashings and valleys.
In a London terrace or conversion, the roof frequently joins the neighbours’ roofs and shares their stacks and gutters, with parapet walls and party-wall upstands marking where one roof ends and the next begins. That matters for anyone buying in City of Westminster or checking a new roof there: we inspect what we are given access to and can see safely, which may not include a neighbour’s side. For a flat, the lease typically says who looks after the roof.
With the Standard Survey, you also get moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where applicable, structural analysis and an in-person consultation.

New roof snagging in City of Westminster: local notes
Many homes in inner London are Victorian and Edwardian terraces, often with Welsh slate roofs. A butterfly roof with a central valley gutter, tucked behind a parapet wall, is common on these houses. In a house like that, shared stacks, party-wall upstands and lead flashings all need looking at as far as they can be seen. Material and age explain a lot of what turns up on the day, whether the roof is old or brand new. The wider area around City of Westminster has a long history of building, with Handel Hendrix House about 0.3 miles east. If your house is among the older ones, expect a mix of original materials and later repairs on the roof, and any change of roofing material on a listed home needs checking with the council first.
Landlords with a home close to Bond Street station may find that a written report helps before buying a rental or paying for a new roof on one. Take an older house close to St Mark's: the roof may have had decades of patch repairs, and the survey shows where they are.
City of Westminster is about 3 miles west of London, in Greater London. We survey roofs in City of Westminster and the rest of Greater London. City of Westminster is one of the places in Greater London we cover.

Near you in City of Westminster
We work in homes and buildings around LITE Regal International School, Royal Society of Medicine Library and Devonshire Arms, among other places. Nearby too are The St Marylebone CofE School (0.5 miles north) and Hyde Park (0.6 miles south-west). There is a railway station in City of Westminster itself: Bond Street station.

Should I look at the roof myself first?
A lot can be seen from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please don’t climb up for a closer look.
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry and it will help the survey.
When to book a survey in City of Westminster
Flashings are a common source of snags. Loose or badly fitted flashings can let water in at the first heavy rain.
A survey makes sense if you’ve noticed:
- Broken coverings left on a new roof
- Offcuts and broken tiles left behind
- Vents that weren’t fitted or are covered
- Cracked lower roofs or marked walls after the work
Controlled parking zones are common in London, so mention any permit rules for City of Westminster, along with any off-street space.
Questions to ask before booking
- Which limits apply to the survey
- Will the report include photos?
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- Which viewpoints they use to see the roof
The survey, step by step
The visit normally starts outside and finishes in the loft: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. In total, it takes between one and two hours for most houses, and longer for a large or complex roof. Many London properties are flats or terraces with no side access, so rear slopes are viewed from windows, the loft or, where a flight is allowed, by drone. Mention any building rules, key holders or managing agents when booking.
- First, you let us know what the roofer did and any concerns you have.
- The new coverings, ridge, hips and verges are inspected where it is safe to see them.
- Flashings, valleys, gutters and visible underlay at the eaves are looked at.
- We look in the loft space, where there’s safe access, and around the property for debris or damage.
- You get a photo report listing the snags we found.
Before the survey
- Have keys ready for side gates, garages or roof access doors
- Make sure pets are kept safely away
- Clear the way to the loft hatch

Common questions in City of Westminster
Can parking be tricky for a visit in City of Westminster?
London parking needs a little planning, so let us know about permits, bays or a driveway as you book. The visit is then planned around what’s available.
Do you cover City of Westminster?
Yes. We survey roofs across London and South East England, and City of Westminster is part of that. You can phone 07833 053749 or use the contact form with the address and a few details, and we’ll talk through which survey suits.
Is it the same as a RICS Level 2 or Level 3 survey?
No. Our survey is a roof survey, not a RICS Level 2 or Level 3 survey of the whole building. It focuses on the roof, so it sits alongside a building survey rather than replacing it.
How do I arrange new roof snagging in City of Westminster?
To book, phone 07833 053749 or email us with the address, the type of property and what’s prompted the survey. We’ll confirm the price and find a day that suits.
Can you tell me if my roof has asbestos?
No. Our report may flag materials that could contain asbestos, but only a specialist asbestos surveyor can confirm it. It may be present in buildings built or refurbished before 2000.
Do you look in the loft space?
Where it is relevant to the survey and there is safe access, yes. Please clear anything stored under the hatch.
Do you carry professional indemnity insurance?
Every survey is covered by professional indemnity and public liability insurance.
Why act early in City of Westminster
A minor snag left alone can turn into a leak. A slipped verge tile or a loose flashing may let water through during the first winter. Finding them early means they can be dealt with quickly. Blocked gutters and hoppers on London houses overflow and soak brickwork, which can lead to damp inside. A blocked outlet ignored for a winter or two can mean damp walls inside.
Every price we give includes VAT. Our price is from £150, including VAT. We confirm the price for your roof before booking.
