Coulsdon Flat Roof Survey
Need a flat roof survey in Coulsdon? We can help, with findings in writing and pictures to back them up. Book a weekday or weekend visit.
- Signs of deflection in the roof deck
- Failed seals around rooflight kerbs
- Standing water left after rain
DIY checks: what’s safe
Look up at the roof after a storm, from the ground: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Don’t go up yourself.
You can learn a lot from ground level. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.
Flat roof survey in Coulsdon: 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. The survey notes any ponding, the state of each outlet and any dips that hint at a sagging deck. If the deck itself looks like a structural concern, we’ll recommend a structural engineer. We survey single-ply membranes, GRP fibreglass and EPDM rubber, and common reasons people get in touch are cracked or split membrane and loose or cracked edge trims.
Offices, shops and blocks of flats across London often have large flat roofs with plant, rooflights and walkways. Every penetration and upstand is a place where a membrane can fail. For a building in Coulsdon, access is agreed with whoever manages the roof ahead of the visit. Plant bases, rooflights and cable entries are all places where water can get in.
Where we cannot see part of the flat roof, the report says so. You will know exactly what was inspected and what wasn’t.

Questions from Coulsdon
Is parking a problem for a survey in Coulsdon?
It rarely stops a survey, but it is worth planning. Let us know the parking rules on your street and we will work around them.
Is Coulsdon in the area you cover?
Yes, Coulsdon is one of the places we work. The survey and report are the same in Coulsdon as anywhere else, and visits run on weekdays and weekends.
Do you take photos of the roof?
Yes. Photos are taken throughout the survey, and they go into the written report alongside our recommendations.
Can you test old roof sheets for asbestos?
Our survey doesn’t include asbestos testing. 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 long does the survey take?
It typically takes about one to two hours for a small flat roof at home, and longer for a large commercial one. The written report follows by email.
Can you inspect my roof with a drone?
Yes, where it’s applicable. Flights depend on the weather on the day and airspace rules, and we check for restrictions near airports before flying. We hold a CAA Flyer ID and Operator ID.
Which flat roof coverings do you cover?
Felt, mastic asphalt, EPDM rubber, GRP fibreglass and single-ply membranes are all part of the work. We record what the covering is and how it is holding up.
What we’re asked to look at in Coulsdon
A buyer’s general survey often recommends a closer look at a flat roof. Building owners and managing agents book to plan maintenance, or before a sale or a new lease. In each case, the report gives a written, photographed record of the roof’s condition.
A survey can pick up problems such as:
- Splits, cracks and crazing
- Edge trims that have lifted or split
- Outlets that hold water back
- Gaps at upstands and abutments
For site and facilities teams at buildings like Smitham Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
What to check before booking
- What follow-up you get after the report
- Whether the loft is part of the inspection
- How much experience they have with roofs like yours
- How they plan to inspect the roof safely
The survey, step by step
We don’t take risks to get a closer look. Everything that can safely be seen is inspected, and anything we can’t see is noted in the report. Most visits take roughly 1–2 hours for most houses; commercial roofs usually need 3–4 hours. For a visit in Coulsdon, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor the property is on and how to get into the loft. On the day, the roof is looked at from the ground, from windows, from inside the loft space and from the roof where it is safe.
- First we go through the roof, what’s beneath it and any problems so far.
- The roof is viewed from safe positions, including the roof itself where that is safe.
- We check the covering for splits, blisters, ponding and wear.
- We photograph and record the outlets, upstands, trims and rooflights.
- The report, with photographs and recommendations, comes to you by email.
Before we arrive
- Let us know about parking near the property
- Note where any stains or damp appear
- Make a note of anything you’d like us to look at

What a flat roof survey looks like in Coulsdon
With Nonsuch Mansion about 4.9 miles north-west, Coulsdon sits in an area with a long building history. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material. Alongside Victorian and Edwardian terraces, outer London has a great many interwar semis, often with hipped roofs of clay or concrete tiles. Hips, bay roofs and later loft conversions are typical of those semis, if your home is one of them. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
Take an older house close to St Andrew's Church: later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear. For landlords with property near Coulsdon South station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

Knowing what’s needed early gives you time to plan it calmly, rather than in a rush after a leak.

Practical tips
A few practical points come up again and again on our surveys. They apply to most roofs:
- Keep records of when the roof was laid and what work has been done
- Check that new brackets or units haven’t damaged the covering
- Note any new marks on ceilings beneath the roof
- Note where water lies after a downpour
Buyers can take the findings back to the seller or the agent. It can support a request for work before completion or a conversation about price, depending on the findings.
Keep foot traffic on a flat roof to a minimum. If access is needed, boards or walkways help protect the covering, and remind them never to step on rooflights or fragile sheets.
