Flat roof surveys for homes and businesses in City of Westminster
A flat roof does not shed water the way a pitched roof does. Because rain sits on it for longer, a small split, an open seam or a blocked outlet matters more. The surface, the falls, the upstands and the trims are all looked at closely, and we note any sign that the deck below has got wet. The aim is to find problems before they show up as a stain on a ceiling. If you’re worried about splits and cracks in the covering and blisters and bubbles in the covering, we can find out what’s behind it, whatever the roof.
Water getting through a flat roof in London can travel under the covering and appear some way from the hole. Upstands against parapets, outlets and the edge where flat meets pitched are common entry points. In a converted house in City of Westminster, the roof above may belong to the building rather than one flat.
The report is yours to share with whoever needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

Practical tips
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Book a survey every few years
- Make sure new fixings through the roof are properly sealed
- Note any new marks on ceilings beneath the roof
- Keep outlets clear of leaves and moss
You get the report by email and can pass it to a roofer, your solicitor, the seller or your managing agent. It’s written in plain English, with a photo of each defect, so anyone reading it can see what we saw.
Small defects are simpler to deal with while they’re still small. Prompt repairs tend to add years to a flat roof.
What happens on the day
It helps to start with what’s prompted the survey: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. The visit normally takes about 1–2 hours at most homes, rising to roughly 3–4 hours on a commercial building. In City of Westminster, visits are available on weekdays and at weekends. It helps if you can point us to a visitor permit or a nearby bay, and to clear a path to the loft hatch. Upstairs rooms at the back are useful too, as they often give the best view of a rear addition.
- First we go through the roof, what’s beneath it and any problems so far.
- We check the roof from ground level, windows and the roof where it is safe.
- We check the covering for splits, blisters, ponding and wear.
- We photograph and record the outlets, upstands, trims and rooflights.
- The report, with photos and recommendations, comes to you by email.
Getting ready for the survey
- If you are buying, let the agent know when we’re coming
- Keep pets in another room
- Let us know about any leaks, stains or damp patches you know of
Arrange a survey
A quick phone call is normally the easiest start: ring 07833 053749 or drop us an email and we will ask a few questions about the roof. You will have a price before anything is arranged.

What else we do in City of Westminster
Should I look at the roof myself first?
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.
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.
Honest limits
A survey is a careful look at the flat roof, but it can’t do everything. The main limits are:
- A fixed date for when the roof will need replacing
- Structural calculations, which need a structural engineer
- Whether old sheeting or boards contain asbestos

City of Westminster: your questions answered
Do you look at commercial flat roofs near City of Westminster, like hotels?
Yes. As well as homes, we look at flat roofs on offices, hotels, blocks of flats and commercial units. Larger commercial roofs are quoted for the building, and roof access is agreed with you ahead of the visit.
Is parking a problem for a survey in City of Westminster?
It rarely stops a survey, but it is worth planning. Let us know the parking rules on your street and we will work around them.
Are you insured?
Every survey is covered by professional indemnity and public liability insurance.
Is this an asbestos survey?
No. Asbestos surveys and sampling aren’t something we do. Where a material might contain it, like old cement sheets on a building from before 2000, the report flags it.
Will you go up on the roof?
Not unless it is safe. Safe viewpoints, the roof space and a drone where applicable cover most of what’s needed.
What happens after the survey?
You will receive the report by email, and you decide the next step: use it with a seller, an insurer, a roofer or a managing agent.
What’s the best way to book?
It’s easiest to ring 07833 053749 or email us. Give us the address and a few details about the roof, and we will recommend the right survey. Surveys run seven days a week.
Flat and commercial roofs around City of Westminster
Historic houses such as Handel Hendrix House, about 0.3 miles east, show how far back building in the area around City of Westminster goes. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof, and the council can say whether a home is in a conservation area. City of Westminster has a number of hotels within about a mile and a half, and like offices and blocks, hotels often sit under flat roofs. If you look after one, a leak through a flat roof can put a room out of use.
Take a building like St Vincent's Catholic Primary School: large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. For businesses in and around places such as Kingly Court, the flat roofs over shops and commercial units are worth checking before a leak, not after. The streets around a church such as St Mark's are often among the oldest in a place, and if your home is one of the older ones nearby, flat-roofed rear additions and dormers added over the years are worth checking.
