Flat Roof Survey in New Southgate
We take a careful look at the flat roof at your property in New Southgate, and put it all in a written report with photographs.
- Standing water left after rain
- Loose or cracked edge trims
- A sagging deck under the covering
How we price flat roof surveys
Not every roof costs the same to survey, and it comes down to:
- House, block, shop or office
- How many separate roofs there are, like extensions, dormers and garages
- Height and safe access
- Roof area
Prices start from £150, including VAT. What you pay depends on the size and height of the roof, how it can be seen safely and the package you choose.
What to tell us when you get in touch
If you can, have these to hand when you contact us:
- Access details, such as a loft hatch or a shared roof
- The reason for the survey, such as buying, a leak or storm damage
- The kind of building and roof involved
- Pictures of the roof from a safe spot, if you have them
Every survey is priced before it is booked, so you know where you stand. Our price is from £150, including VAT. For a price for your roof, phone 07833 053749 or email us.
Flat roof survey in New Southgate
Water through a flat roof doesn’t always come in where the stain is. It may start at a split, a lifted seam or a failed upstand well away from the damp patch. Our survey covers the whole roof, not just the part above the mark, and photograph anything that could let water in. Whoever carries out the work then has a clear starting point. Common reasons to book are damaged trims at the roof edge and dips that suggest the deck is deflecting, on upstands and outlets, GRP fibreglass and EPDM rubber.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats and offices. They’re covered in felt, asphalt, EPDM rubber, GRP fibreglass or single-ply membranes, each with its own weak points. Which one is on a roof in New Southgate shapes how it’s checked. Older flat roofs are frequently felt or asphalt, newer ones rubber or GRP.
After the visit, you get a written report with photographs, sent by email. It explains the condition of the flat roof, the defects we found and what we recommend.

How the survey works
After the inspection, everything we found is written up in a report with photographs, emailed to you. On timing, most surveys take an hour or two for a small flat roof at home, and longer for a large commercial one. From the street, a London terrace normally shows only its front slope or parapet, so a visit in New Southgate moves between viewpoints: the pavement, upstairs windows, the loft and any safe spot at the back. Shared stairs or a basement flat? Let us know who holds the keys.
- First we go through the roof, what’s beneath it and any problems so far.
- We look at the roof from ground level, 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 photos and recommendations, comes to you by email.
How to prepare
- Tell us about any leaks, stains or damp patches you know of
- Keep pets inside or away from the areas we are looking at
- Make a note of anything you’d like us to look at
Arrange a survey
If you are buying, it’s useful to book soon after your offer is accepted, so there’s time to use the report before exchange. For any other survey, just ring 07833 053749 or drop us an email when you are ready.
Advice
Honest limits
Some things can’t be seen without opening up the roof, so a survey has limits:
- A promise that the roof won’t leak in future
- Whether the deck or joists are strong enough
- What’s under the membrane without opening it up
Not sure which survey suits your roof? You can ring 07833 053749 or send us an email and we’ll tell you. What a survey covers and doesn’t.
Roof types and parts we check
- Felt flat roofs
- Single-ply membranes
- EPDM rubber
- GRP fibreglass
- Mastic asphalt
- Upstands and outlets
Can I check my roof myself?
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry.
During heavy rain, look at the gutters from ground level or a window. Overflowing water can point to a blockage or a sagging run.
Flat roofs in New Southgate
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, frequently with hipped roofs of clay or concrete tiles. On a semi of that age, the small roofs over the bays, the hip tiles and any later dormer each need their own look. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops. About 2.9 miles south-west lies Heath Hall, a reminder of how long the area around New Southgate has been built on. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead.
If you live in an older home near St Paul's Church, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. Parking in New Southgate, as in most of London, takes a little planning: let us know about permits, visitor bays or off-street space when booking. Anyone responsible for a site like St Paul's CofE Primary School N11 will know that large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

What happens if roof problems are left?
Caught early, a split or open seam in a flat roof is often a small repair. Left alone, water can soak the insulation and the deck, and the job grows. A survey now shows which you’re dealing with. In New Southgate, 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 small, low roof with good viewpoints takes less time than a tall, complicated one, and the package matters as well. We will give you the figure before anything is booked.

Questions from New Southgate
Is New Southgate in the area you cover?
We do. The survey and report are the same in New Southgate as anywhere else, and visits run on weekdays and weekends.
How do I find out if my home in New Southgate is listed?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
When does the report arrive?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. All of them come by email.
Does the report include photos?
Yes, every report has them. Each finding is shown in a picture where possible, so you can see what we mean.
Can you survey in bad weather?
It can, depending on the survey. Drones cannot fly safely in strong wind or heavy rain, and thermal imaging works best with a dry roof, little wind and a sunny day beforehand. We will rearrange with you if the weather isn’t right.
What’s in the report?
It sets out what we found, why it matters and what we recommend, backed by photographs. It also says if any part of the roof couldn’t be seen safely, so you know exactly what was covered.
What happens after the survey?
The report comes by email, and you decide the next step: use it with a seller, an insurer, a roofer or a managing agent.
Before and after the survey
Over many surveys, some simple habits stand out as worth the effort:
- Keep outlets clear of leaves and moss
- Check new fixings through the roof are properly sealed
- Plan a survey before the covering reaches the end of its usual life
- Keep clear of rooflights and fragile roof sheets
The report is emailed to you, ready to share with a roofer, the seller or a managing agent. It’s written in plain English, with a photograph of each defect, so others can follow it without going up to look.
After heavy rain, look at the roof from an upstairs window if you can. If water is still there a day or two later, have it checked.
