Flat roof surveys for homes and businesses in Islington
Ponding is frequently the first sign that something on a flat roof isn’t right. It can mean the falls were never right, an outlet is blocked or the deck has started to sag. The survey notes any ponding, the state of each outlet and any dips that hint at a sagging deck. Where the deck may be a structural issue, our report says a structural engineer should look at it. We are often asked to look into upstands pulling away from walls and signs of deflection in the roof deck, across felt flat roofs, GRP fibreglass and upstands and outlets.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, each with its own weak points. In Islington, 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.
Nothing in the report is left vague: if work is needed, the report says so clearly.

What affects the cost of flat roof surveys
When we price a survey, we consider:
- The type of building, from a house to a block or an office
- The number of roofs, including extensions and garages
- Chimneys, valleys, parapets and other details
- Basic, Standard or Premium
There are three survey packages: Basic from £150, Standard from £250 and Premium from £400, with VAT included. What your roof costs depends on its size, access and what you want to find out.
Booking your survey
Before you get in touch, it’s useful to have:
- Where the property is, with the postcode
- What’s prompted the survey
- Any stains, drips or damp patches you’ve seen indoors
- Any photos you have, taken from ground level or a window
Unsure which package suits your roof? The easiest way is to phone 07833 053749 or drop us an email and describe the roof and why you want it surveyed. We’ll explain the options and the price.

Local flat roofs in Islington
Dr Johnson's House, about 1.6 miles south, is one of the historic houses in the wider area around Islington. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area. Inner London’s Victorian and Edwardian terraces often have Welsh slate roofs. A butterfly roof with a central valley gutter, tucked behind a parapet wall, is common on these houses. If your home in Islington is one of them, lead flashings, party-wall upstands and shared chimney stacks are part of the picture too. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops.
Shop and office owners around Brunswick Centre may find that a flat roof over a business is out of sight and out of mind until it leaks. Landlords with a home close to Essex Road station may find that flat roofs over rear additions and dormers in rented property are worth checking between tenancies. If your house is among the older ones in the streets near St Mary's Church, the joins between later flat roofs and the old walls are where problems normally start.
Islington is about 3 miles north-east of City of Westminster, in Greater London. Houses, flats, blocks and commercial buildings in Islington can all book flat roof surveys, with a written report and photographs every time. Islington is one of the towns and villages in Greater London we cover for flat roof surveys.
Here we cover the N1, N7, NW1 and EC1V postcode area for flat roof surveys. We cover properties on Gibson Square, Old Royal Free Square and Cloudesley Square. You’ll find Islington on the B515 and A5203, which makes it simple to reach. Close by, we survey roofs in Pentonville (1 mile south), Angel (1 mile south), Barnsbury (1 mile north-west), Clerkenwell (1 mile south) and Lower Holloway (1 mile north-west). We also work in nearby towns such as London (3 miles south), City of Westminster (3 miles south-west), Kensington (5 miles south-west), Walthamstow (5 miles north-east), Hampstead (3 miles west) and Ruislip (13 miles west).
Landmarks near Islington
Typical jobs here are in homes near Islington Green School, The King's Head Public House and Pilsudski Institute of London and the streets around them. Also close by are Barnard Park (under half a mile south-west) and St Mary's CofE Primary School (less than half a mile east). There’s a railway station in Islington itself: Essex Road station. Nearby you’ll also find King's College Hospital Charity (0.7 miles north-west) and Montfichet's Tower (1.7 miles south). The countryside around Islington includes Barnsbury Wood and Ludgate Hill.
What we look for on each type of roof
Single-ply membranes
Single-ply PVC and TPO membranes are common on commercial roofs and newer buildings. The survey looks at welded seams, edges, fixings and signs of damage.
GRP fibreglass
GRP roofs are laid as a resin and glass-fibre layer over boards. We look for cracks at board joints, around trims and at upstands.
Islington questions
Does a conservation area affect roof work in Islington?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case.
Will parking be an issue for a roof survey in Islington?
Parking in Islington, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Do I need to be at home?
That depends on the survey. For inside areas and the loft space, someone has to give us access, while outside access can be discussed as you book.
How long will you be at the property?
It usually takes roughly 1–2 hours at most homes, with bigger or more complicated roofs taking longer. The report follows by email.
What does ponding on a flat roof mean?
Ponding is worth looking into. It can point to blocked outlets, poor falls or a deck that is sagging, and water that sits wears the covering sooner. We record where it sits and the likely cause.
What does the report include?
It sets out what we found, why it matters and what we recommend, backed by photos. Anything we couldn’t see safely is noted too.
Is a flat roof survey the same as a building survey?
No. It’s a survey of the flat roof. It isn’t a RICS Level 2 or 3 survey of the whole building, and it isn’t a structural engineer’s report. It frequently sits alongside a buyer’s building survey.
How the survey works
A survey visit follows a simple order: we hear what you’ve seen, look at the roof from every safe viewpoint, photograph what we find and record our findings for the written report. Most visits take roughly 1–2 hours for a house; commercial roofs usually need 3–4 hours. Surveys in Islington can be booked for any day of the week. It helps if you can point us to a visitor permit or a nearby bay, and to clear a path to the loft hatch. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- First you give us the address, what the roof covers and any leaks you’ve noticed.
- We check the roof from wherever it can be seen safely.
- We check and photograph the covering, the falls, the upstands, the outlets, the trims and any rooflights.
- We check the rooms or spaces under the roof for staining where we can reach them.
- The findings are written up with photographs and recommendations and emailed to you.
How to prepare
- Gather any invoices or paperwork from past roof work
- Have any questions written down, so nothing gets missed
- Mention any parking restrictions on your street
Book a survey
You can call us seven days a week, including Saturdays and Sundays. For a price or to book, ring 07833 053749 or send us an email.
Advice
What we cannot see
It helps to know what a survey won’t do before you book:
- Asbestos testing, which needs a specialist asbestos surveyor
- Areas we can’t see or reach safely, including fragile rooflights and sheeting
- Hidden layers beneath the covering
If in doubt, call 07833 053749 or use the contact form and we will point you to the right survey. What a survey covers and doesn’t.
Roof types and parts we check
- Single-ply membranes
- GRP fibreglass
- EPDM rubber
- Mastic asphalt
- Upstands and outlets
- Felt flat roofs
Should I look at the roof myself first?
Your own check is a good start, but it is not a survey. You won’t see flashings, valleys or the backs of chimneys properly from the ground, and those are details a survey looks at closely.
Look up at the roof after a storm, from ground level: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Do not go up yourself.
