Northumberland Park Flat Roof Survey
Not sure what state the flat roof is in? We carry out flat roof surveys in Northumberland Park and across Greater London, with plain-English findings.
- Leaks around rooflights
- Loose or cracked edge trims
- Ponding water that does not drain away
Checking the roof from the ground
Your own check is a good start, but it isn’t a survey. From ground level, valleys, flashings and the backs of chimneys are often out of sight, and those are details a survey looks at closely.
It helps to keep a record: dates of leaks, photos from ground level and any work done on the roof. Send it with your enquiry.
Flat roof surveys for homes and businesses in Northumberland Park
A Basic Survey, from £150, covers a visual inspection, a condition report, photos and written recommendations. For moisture detection and a structural check, the Standard Survey starts from £250. On a flat roof, moisture readings can help show whether water has got under the covering. Larger commercial roofs are quoted for their size. If you’ve noticed blocked or damaged outlets and splits, cracks and crazing, we can find out what’s behind it, whatever the roof.
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. In Northumberland Park, as anywhere in London, the right approach depends on what the roof is made of. Older flat roofs are frequently felt or asphalt, newer ones rubber or GRP.
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 it applies, structural analysis and an in-person consultation.

What happens if roof problems are left?
Most flat roofs are out of sight, so they’re easy to forget. Owners frequently learn the roof is at the end of its life only when it leaks. Regular surveys mean it will not come as a surprise. In Northumberland Park, as across London, an overflowing gutter soaks the wall below, which can lead to damp inside. A small blockage left for a few winters becomes a damp problem.
Price depends partly on the package: from £150 for Basic, £250 for Standard and £400 for Premium, with VAT included. Size, height and access can affect the price too.

Flat and commercial roofs around Northumberland Park
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. Next to the main roofs there’s typically a flat roof somewhere, whether on an extension, a garage or a commercial unit. Historic houses such as Bruce Castle, about 0.8 miles south-west, show how far back building in the area around Northumberland Park goes. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof.
For a London address like Northumberland Park, it helps to know about controlled parking before the day. Take a building like Lea Valley Primary School: a large flat roof with a good many outlets and rooflights has many places where a membrane can fail.

Common questions in Northumberland Park
Is Northumberland Park in the area you cover?
Yes, Northumberland Park is within the area we cover. We cover the whole of London and South East England. Just phone 07833 053749 or use the contact form and let us know about the property.
Can parking be tricky for a visit in Northumberland Park?
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.
How long does the survey take?
It normally takes an hour or two for a small flat roof at home, and longer for a large commercial one. The report follows by email.
What does the report include?
You get our findings in writing, part by part, with photos, finishing with recommendations. The most urgent items are made clear.
Do you look in the loft space?
Yes, where the survey calls for it and there is safe access. Inside, we look for damp, staining, gaps and sagging, as far as the space allows.
Will the survey show why my flat roof is leaking?
We check the whole roof, since water can travel before it shows inside. Every split, lap, upstand, outlet and rooflight we can see is checked. Where nothing visible explains the leak, the report says what to try next.
Does someone need to be in?
It depends on what we need to see. Inside the building and in the loft, we need someone to let us in.
How the survey works
After the inspection, everything we found is written up in a report with photos, sent to you by email. As for time on site, it usually takes an hour or two for a small flat roof at home, and longer for a large commercial one. Surveys in Northumberland Park can be booked for any day of the week. London parking is often by permit or pay-and-display, so it’s useful to know what’s near you. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- You send us the address and, for commercial roofs, an idea of the roof’s size.
- Inside, we look for signs of water under the roof where we can reach.
- We view the roof from safe positions and never walk on fragile surfaces.
- Each defect is photographed and its likely cause noted.
- The report explains the condition and recommends what to do first.
Getting ready for the survey
- For a flat or shared roof, check access with whoever owns or manages the building
- Make a note of anything you’d like us to look at
- Show us where any leaks or stains appear

Advice
What a flat roof survey does not cover
Our findings are based on what we can see safely on the day, so some things are outside what a survey can do:
- What’s under the membrane without opening it up
- Testing older roof sheets for asbestos
- A structural engineer’s assessment of the deck

- GRP fibreglass
What we’re asked to look at in Northumberland Park
The surface of a flat roof heats up and cools down far more than the rooms below. This constant movement works at laps, seams and board joints, and in time it can open up splits and cracks. Older coverings that have lost their flexibility are the most likely to suffer.
Most people get in touch when they’ve noticed one of these:
- Splits and cracks in the covering
- Outlets choked with leaves and silt
- Water getting in at rooflights
- Standing water left after rain
If your home is one of the older ones in the streets near St Paul's Church, flat-roofed rear additions and dormers added over the years are worth checking.
Choosing a roof surveyor
- Whether the loft space is looked at, where there is one
- Do they have a CAA Flyer ID and Operator ID for drone work?
- Is VAT included in the price?
- Their report turnaround times

For landlords and managing agents
Where a roof is shared: we need access agreed with the building owner or managing agent. Let us know about it when booking and we will plan the survey around it.
We also survey roofs for businesses and commercial landlords, including offices, shops and units. Bigger roofs take more time, and they’re priced for the size.
