Flat roof surveys around Harringay
About 1.6 miles north-east lies Bruce Castle, a reminder of how long the area around Harringay has been built on. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs. Close to the centre of London, a great many houses are Victorian or Edwardian terraces, many of them roofed in Welsh slate. Many have butterfly roofs draining to a central valley gutter, with parapet walls and gutters hidden behind them. Lead flashings, party-wall upstands and shared chimney stacks are typical of these houses, if yours is one of them. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
If you run a business near The Mall Wood Green, a flat roof over a business is out of sight and out of mind until it leaks. If you live in an older home near St Paul's Harringay, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

Flat roof survey in Harringay: what you get
A flat roof leak often travels before it shows on the ceiling. It can run along the deck from a split, an open lap or a failed upstand some distance away. That’s why we check every detail across the roof, not only the area above the stain, with photos of anything that could be letting water in. A roofer can then start from a clear picture of the problem. We survey EPDM rubber, single-ply membranes and upstands and outlets, and common reasons people get in touch are damaged trims at the roof edge and gaps at upstands and abutments.
London has a lot of flat roofs: rear additions, dormers, roof terraces and the roofs of blocks and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, each with its own weak points. Which one is on a roof in Harringay shapes how it’s checked. Older flat roofs are often felt or asphalt, newer ones rubber or GRP.

Harringay questions
Do you carry out roof surveys in Harringay?
Yes, Harringay is within the area we cover. We cover the whole of London and South East England. Just ring 07833 053749 or send us an email and let us know about the property, and we will talk through which survey suits.
Is parking a problem for a survey in Harringay?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available as you book.
What do I do with the report?
We email you the written report with photographs and recommendations. You can use it to talk to a seller, an insurer, a roofer or a managing agent, whichever applies.
Are you insured?
Our cover is professional indemnity plus public liability, and details are available on request.
When does the report arrive?
It depends on the package: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. Reports are sent by email.
Can you find where water is getting through my flat roof?
Our survey looks across the whole roof, not only above the stain. Every split, lap, upstand, outlet and rooflight we can see is looked at. If the cause can’t be seen, we’ll say so and suggest what would help.
Can you tell me how long my flat roof will last?
We don’t give a fixed number of years, because it depends on upkeep, weather and how the roof was laid. Our report describes the condition and what needs doing, and when.
How the survey changes by roof type
Felt and built-up roofs
The edges and upstands of a felt roof are typically where trouble starts. We check each one and photograph any that have split or pulled away.
Mastic asphalt
Asphalt roofs are common on older flats, walkways and commercial buildings. The survey checks for crazing, cracking, blistering and splits where the asphalt turns up the walls.
Why get it checked now?
Standing water on a flat roof rarely sorts itself out. It typically points to an outlet, the falls or a sagging deck, and each wet season wears the covering further. Knowing the cause early gives you more choice over what to do. Behind a London parapet, a blocked gutter can sit full of water without anyone seeing it. When the stain finally shows, the damage underneath is often older than it looks.
Prices quoted always include VAT, and the written report is part of the package. Flat roof survey starts from £150, including VAT. Size, height and access decide where your roof falls.
Why us?

How the survey works
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 small flat roof at home, and longer for a large commercial one. For a visit in Harringay, parking and access are the things to plan: let us know about parking, the floor the property is on, any shared entrance and loft access. On the day, the roof is looked at from ground level, from windows, from inside the roof space and from the roof where it is safe.
- We agree the roof to be surveyed, its use and any leaks you know about.
- We look at the roof from the ground, windows and the roof where it is safe.
- The covering is checked for wear, splits, blisters and standing water.
- We photograph and record the outlets, upstands, trims and rooflights.
- The report, with photographs and recommendations, comes to you by email.
How to prepare
- Buyers: confirm access with the estate agent or seller
- Keep pets inside or away from the areas we are looking at
- Gather any invoices or paperwork from past roof work
Book a survey
Prices start from £150, including VAT. What you pay depends on the roof’s size, access and the package, and you can call 07833 053749 or use the contact form to find out.

Before and after the survey
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Note the date and type of any roof work
- Book a survey every few years
- Check that new brackets or units haven’t damaged the covering
- Note where water lies after a downpour
You get the report by email and can pass it to a roofer, your solicitor, the seller or your managing agent. Each defect is described in plain words and shown in a photo, so others can follow it without going up to look.
Have the roof surveyed every few years, and after any work that goes through it. You will spot changes early and have a record to look back on.
Do you need a flat roof survey in Harringay?
Many flat roof problems start at the details rather than the main surface. Upstands, trims, outlets and rooflight kerbs each move and weather in their own way. Where they weren’t finished well, they tend to fail before anything else.
These are some of the problems a survey can pick up:
- Failed upstands where the roof meets a wall
- Failed seals around rooflight kerbs
- Ponding water that doesn’t drain away
- Edge trims that have lifted or split
For a London address like Harringay, it is useful to know about controlled parking before the day, along with any off-street space.
