Flat roof survey in Hornchurch Marshes, Greater London
Wondering about the flat roof at a property in Hornchurch Marshes? We carry out flat roof surveys in Hornchurch Marshes and across Greater London, with plain-English findings.
- Blistering in felt or asphalt
- Standing water left after rain
- Upstands pulling away from walls
How it works
The visit has one job: to see as much of the flat roof as can safely be seen and record it clearly. Notes and photos go into the written report. It typically takes about one to two hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. Many London properties are flats or terraces with no side access, so the back of the roof is frequently seen from upstairs windows, from inside or, where a flight is allowed, from the air. If the building has a managing agent or access rules, tell us when booking.
- We start with the address and, on larger roofs, the roof area and access.
- Inside, we look for signs of water under the roof where we can reach.
- The roof is inspected from every safe viewpoint, without walking 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
- Have any paperwork from past roof work to hand
- If you’re buying, check with the agent that we can get in
- Make a note of anything you’d like us to look at
Booking a survey
A quick phone call is typically the easiest start: phone 07833 053749 or send us an email. You’ll have a price before anything is arranged.

Flat roof surveys for homes and businesses in Hornchurch Marshes
Ponding is frequently the first sign that something on a flat roof is not 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. If you’ve noticed leaks around rooflights and splits and cracks in the covering, a survey will tell you what’s going on, on EPDM rubber, mastic asphalt and upstands and outlets alike.
On a London roof terrace or a flat roof over a back addition, water frequently runs under the covering before it shows. Upstands against parapets, outlets and the edge where flat meets pitched are common entry points. In a converted house in Hornchurch Marshes, the roof above may belong to the building rather than one flat.
What you get is a clear record of the flat roof on the day we saw it. That makes it useful now and a handy reference later, such as when you want to compare after future work.

FAQs for Hornchurch Marshes
Is my home in Hornchurch Marshes listed or in a conservation area?
We can’t confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material.
Will parking be an issue for a roof survey in Hornchurch Marshes?
It depends on the street. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well.
What does a roof survey cost?
Our price is from £150, including VAT. Our three packages are Basic from £150, Standard from £250 and Premium from £400, inc. VAT.
Do you need to get into the loft?
Where it is relevant to the survey and there’s safe access, yes. A clear path to the hatch helps, and if the loft cannot be reached safely, the report says so.
What happens after the survey?
We email you the written report with photos and recommendations. It’s yours to share with a seller, insurer, roofer or managing agent, whichever applies.
Can you give me structural calculations?
No. We’re experienced roof surveyors, and visible signs such as sagging are noted, but we don’t provide calculations or an engineer’s opinion. If one is needed, the report says so.
Do I have to be there for the survey?
It depends on what we need to see. For inside areas and the loft space, someone has to give us access; we will agree the details as you book.

Why it’s worth a survey now in Hornchurch Marshes
By the time a flat roof leak shows indoors, water has already passed through the roof build-up. We can pick up worn covering and failing details sooner, while there’s still time to plan the work. In Hornchurch Marshes, as in much of London, water from a roof defect can reach a neighbour’s home as easily as yours: a blocked parapet gutter or slipped slate can let water into the flat below or the house next door. Finding it early keeps the work smaller.
Flat roof survey starts from £150, including VAT. Packages run from Basic at £150 through Standard at £250 to Premium at £400, inc. VAT, and we can help you choose.

Different roofs, different checks
Mastic asphalt
With age, asphalt can harden and crack with movement. We note where this is happening and how widespread it looks.
Felt and built-up roofs
Felt roofs often last around 15 to 20 years, depending on how they were laid and looked after. Our report sets out its condition and the areas most at risk.
Can I check my roof myself?
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
Look up at the roof after a storm, from ground level: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Do not go up yourself.
Flat roof surveys in Hornchurch Marshes: local notes
Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often 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. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. Rainham Hall, about 1.1 miles east, is one of the historic houses in the wider area around Hornchurch Marshes. Older homes in the wider area frequently have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and any change of roofing material on a listed home needs checking with the council first.
For businesses in and around places such as Gallions Reach Shopping Park, flat roofs over shops and units are easy to forget until water comes through a ceiling. Landlords with a home close to Dagenham Dock station may find that flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

Before and after the survey
You don’t need to be a roofer to help. Here’s what helps most:
- Keep clear of rooflights and fragile roof sheets
- Note the date and type of any roof work
- Ask contractors to protect the roof if they work on it
- Watch the ceilings below the flat roof for stains
Landlords, owners and managing agents can keep the report as a dated record of the roof. It is useful when planning upkeep and setting budgets, and it gives a baseline to compare against next time.
Small defects are simpler to deal with while they’re still small. Prompt repairs tend to add years to a flat roof.
Common roof problems in Hornchurch Marshes
Buyers frequently book after their home survey suggests a closer look at a flat roof. Building owners and managing agents book to plan maintenance, or before a sale or a new lease. Either way, you get a clear record of the roof, with photographs.
Look out for signs like these:
- Water getting in at rooflights
- Damaged trims at the roof edge
- Blistering in felt or asphalt
- Cracked or split membrane
Hornchurch Marshes is in London, so parking needs planning: a visitor permit or a nearby bay makes the day easier, as a space near the door can’t be promised.
