Southgate questions
How do I find out if my home in Southgate is listed?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you are planning to re-roof in a different material.
Is Southgate in the area you cover?
Yes, Southgate is one of the places we work. The survey and report are the same in Southgate as anywhere else, and visits run on weekdays and weekends.
What will the report tell me?
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.
Do you carry out surveys on Saturdays and Sundays?
Surveys run on weekdays and at weekends. To arrange a date, ring 07833 053749 or send us an email.
Will the survey show why my flat roof is leaking?
We check the whole roof, since water can travel before it shows inside. Splits, open laps, upstands, outlets and rooflights are all checked. If the cause cannot be seen, we will say so and suggest what would help.
Can you test old roof sheets for asbestos?
We do not carry out asbestos surveys. Older buildings, from before 2000, may have asbestos in cement sheets or soffits. We note anything that could contain it, and a specialist asbestos surveyor should check it before it’s disturbed.
How much is a survey?
Our price is from £150, including VAT. Our Basic Survey starts from £150, the Standard Survey from £250 and the Premium Survey from £400, all including VAT.
Flat roof survey in Southgate: what you get
Standing water is one of the first things we look for on a flat roof. It can point to poor falls, a blocked outlet or a deck that is deflecting. We record where water sits, check the outlets and look for dips that suggest deflection. If the deck itself looks like a structural concern, we’ll recommend a structural engineer. We survey GRP fibreglass, EPDM rubber and mastic asphalt, and common reasons people get in touch are raised blisters across the surface and blocked or damaged outlets.
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 block or conversion in Southgate, the flat roof is often a shared part of the building.
You can share the report with anyone who needs it: a seller or estate agent, an insurer, a roofer, a builder or a managing agent.

What we do, step by step
Every roof is different; as a rough guide, the survey takes about one to two hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. You are welcome to ask questions while we’re there. From the street, a London terrace usually shows only its front slope or parapet, so a visit in 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.
- You send us the address and, for commercial roofs, an idea of the roof’s size.
- We check the rooms or spaces under the roof for staining where there is access.
- We view the roof from safe positions and never walk on fragile surfaces.
- We record every defect with a photo and its likely cause.
- You get a report setting out the condition and our recommendations, in order of urgency.
How to prepare
- For flats, make sure roof access has been agreed
- Have any paperwork from past roof work to hand
- Move anything stored under the loft hatch
Booking a survey
Photos help, if you have them. Take them safely from ground level or a window; never climb up to get a better view. To send them or to book, phone 07833 053749 or use the contact form.

Local flat roofs in Southgate
Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. The wider area around Southgate has a long history of building, with Bruce Castle about 3.2 miles south-east. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area.
If you own a rental within reach of New Southgate station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. If you look after a building like Ashmole Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

When to book a survey in Southgate
Flat roofs frequently get walked on for other jobs: cleaning windows, fitting aerials or air conditioning, or clearing gutters. A covering that wasn’t designed for foot traffic can crack or puncture. New brackets and fixings through the roof are another common source of leaks.
People usually book a survey when they’ve noticed one of these:
- Dips that suggest the deck is deflecting
- Water getting in at rooflights
- Blistering in felt or asphalt
- Blocked or damaged outlets
For a London address like Southgate, it’s useful to know about controlled parking before the day, along with any off-street space.

Tips from our surveys
A survey works best with a little help from you, before and after. Some tips:
- Check the outlets after the leaves fall
- Check that new brackets or units haven’t damaged the covering
- Check from a window for ponding after heavy rain
- Treat rooflights and old sheeting as fragile
Once we’ve been, the findings are written up with photos. It explains the covering, its condition and every defect, and what we recommend. Basic reports arrive within 48 hours, Standard reports in 24 to 48 hours and Premium reports the same day.
Get splits, lifted seams and loose trims seen to while they’re small. A flat roof that is looked after between surveys usually lasts longer.
What we look for on each type of roof
EPDM rubber
Rubber roofs can shrink back from their edges or lift where the adhesive has failed. We record any we can see, with photographs.
Single-ply membranes
On single-ply roofs, the welds between sheets are the key detail. We look at seams, corners and the joints around outlets and upstands.
