How a flat roof survey works in Wanstead
Every flat roof covering tends to fail in its own way. Built-up felt tends to blister and crack, asphalt crazes and splits, EPDM can lift at its laps, and GRP can crack at board joints and edge trims. On PVC and TPO single-ply roofs, we look closely at the welded laps, edges and fixings. Once you know the covering and its condition, planning the next step is far easier. If you’re worried about outlets that hold water back and edge trims that have lifted or split, a survey will tell you what’s going on, on EPDM rubber, felt flat roofs and single-ply membranes alike.
Commercial and residential blocks across London often have big flat roofs with plant, rooflights and access walkways. Each pipe, upstand and fixing through the covering is a possible weak point. For a building in Wanstead, access is agreed with whoever manages the roof ahead of the visit. Rooflights, plant supports and pipe entries are common places for a membrane to fail.
Every survey ends with a written report, with photos, emailed to you. It sets out the condition of the flat roof, any defects and our written recommendations.

Surveys for landlords and agents in Wanstead
For blocks of flats, a roof survey helps managing agents and residents’ management companies plan ahead. Recommendations are set out in order of urgency where relevant.
Any of our surveys can be booked by landlords, agents and building managers in Wanstead. For a price for a let property or a block, ring 07833 053749 or send us an email.
Checking the roof from the ground
Your own check is a good start, but it isn’t a survey. You won’t see flashings, valleys or the backs of chimneys properly from ground level, and those are details a survey looks at closely.
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. Leave anything above ground level to a survey.
Signs you need a flat roof survey in Wanstead
People go onto flat roofs for all sorts of reasons: 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.
Signs worth acting on include:
- Damaged trims at the roof edge
- Dips that suggest the deck is deflecting
- Leaks around rooflights
- Gaps at upstands and abutments
If you let a flat or house near Leytonstone High Road station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
Before booking any roof surveyor
- What the survey won’t cover
- Their drone registration, if they fly one
- Is VAT included in the price?
- Whether they hold professional indemnity and public liability insurance
How the survey works
You do not need to do much on the day. Show us any stains, drips or problem areas you know about, and we’ll take it from there. A typical survey takes between one and two hours for a small flat roof at home, and longer for a large commercial one. In a London conversion, the way into the roof space is often from a communal landing or the top flat. If that applies to your building, it helps to agree access with the neighbours or the managing agent first. Everything else is planned around the building, not the postcode.
- First you give us the address, what the roof covers and any leaks you’ve noticed.
- We view the roof from the ground, from windows and from the roof where it is safe to do so.
- Every part of the roof we can see is checked: covering, falls, upstands, outlets, trims and rooflights.
- Inside, we look for damp and staining under the roof where there’s access.
- You get a photo-illustrated written report and our recommendations.
Before we arrive
- Clear the way to the loft hatch
- For flats, make sure roof access has been agreed
- Have any questions written down, so nothing gets missed
Book a survey
If you have photos of the roof, send them over. Pictures from ground level or a window are fine; never climb up to get a better view. To get started, phone 07833 053749 or send us an email.

FAQs for Wanstead
Can parking be tricky for a visit in Wanstead?
It depends on the street. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well, and a driveway is even better.
Do you cover Wanstead?
Yes, Wanstead is one of the places we work. The survey and report are the same in Wanstead as anywhere else.
What does ponding on a flat roof mean?
Ponding is worth looking into. It often means a blocked outlet, poor falls or a dipping deck, and water that sits wears the covering sooner. We record where it sits and the likely cause.
Are you insured?
We’re covered by professional indemnity and public liability insurance.
Can you give me structural calculations?
No. Our survey isn’t a structural engineer’s report. If we see signs that need an engineer’s opinion, we’ll recommend one.
Will you walk on the flat roof?
Where it’s safe, the roof is inspected from the roof itself. Otherwise we use windows, vantage points and the spaces below, and we note any area we couldn’t see. We do not walk on fragile rooflights or sheeting.
I live in a flat. Can you survey the roof?
Yes, if whoever owns or manages the building agrees access. On a shared roof we can only inspect the parts we’re allowed to reach.
Flat roofs in Wanstead
In outer London, interwar semis with hipped, tiled roofs sit alongside older 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 Wanstead has a long history of building, with Valentines Mansion about 1.6 miles east. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material.
Anyone responsible for a site like Wanstead Church School will know that a large flat roof with plenty of outlets and rooflights has many places where a membrane can fail. For businesses in and around places such as 17 & Central, a flat roof over a business is out of sight and out of mind until it leaks.

Why it’s worth a survey now in Wanstead
If you’re buying, find out about the flat roof before you exchange. After that, the cost of any work is yours. Our report gives you specific points to raise with the seller or agent. In a London terrace or conversion, a roof defect rarely stays your problem alone: 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.
To find out what your survey will cost, phone 07833 053749 or use the contact form and tell us about the roof. The price is agreed before a date is set.
