Flat roof surveys for homes and businesses in Walworth
A flat roof doesn’t shed water the way a pitched roof does. Water lies on the surface for longer, so a small split or a blocked outlet can soon lead to a leak. We check the surface, the falls, the upstands and the edge trims, and we look for signs that water has reached the deck. That way, defects are found before they reach the room below. We survey GRP fibreglass, felt flat roofs and mastic asphalt, and common reasons people get in touch are outlets choked with leaves and silt and splits and cracks in the covering.
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 Walworth, access is agreed with whoever manages the roof before 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 explains the condition of the flat roof, the defects we found and what we recommend.

Flat roof surveys around Walworth
Within a mile and a half or so of Walworth there are several hotels. If you look after one, a leak through a flat roof can put a room out of use. Many homes in inner London are Victorian and Edwardian terraces, often with Welsh slate roofs. A butterfly roof with a central valley gutter, tucked behind a parapet wall, is common on these houses. Shared chimney stacks, party-wall upstands and lead work come with this kind of house. Mixed in with those pitched roofs are plenty of flat ones, over rear extensions, dormers, garages and shops.
If you run a business near Gabriel's Wharf, outlets and upstands on commercial flat roofs are the places to check before trouble starts. Hotels and guest houses near Walworth can’t easily close rooms for a leak.

Common roof problems in Walworth
Flat roofs take the full force of the weather on a surface that drains slowly. In time, the covering dries out, cracks and loosens at its edges and laps. Most people book a survey after a leak, before buying, or when they think the roof is getting old.
Things that often lead to a survey include:
- Upstands pulling away from walls
- Blisters and bubbles in the covering
- Outlets choked with leaves and silt
- Loose or cracked edge trims
Landlords with a home close to Elephant & Castle station may find that flat roofs on let property tend to be checked only when they fail, which is the costly way round.
What to check before booking
- How they’ll see the roof: from ground level, the loft, the roof or by drone
- How much experience they have with roofs like yours
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID
- Are they insured for the work?

Tips that help
A survey works best with a little help from you, before and after. Some tips:
- Keep people off the roof unless they need to be there
- Check the outlets after the leaves fall
- Check new fixings through the roof are properly sealed
- Book a survey every few years
Once we’ve been, the findings are written up with photos. It covers the type of covering, its condition and each defect, with our recommendations. Turnaround is within 48 hours for a Basic Survey, 24 to 48 hours for a Standard Survey and the same day for a Premium Survey.
Have the roof surveyed every few years, and after any work that goes through it. That catches changes early and builds up a record of the roof.
Can I check my roof myself?
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date.
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.
Questions from Walworth
Do you cover commercial flat roofs around Walworth?
Yes, we cover commercial roofs as well as homes. Access to the roof is sorted out with whoever manages the building before the day.
Can parking be tricky for a visit in Walworth?
Typically it is manageable with a little notice. Tell us what parking is available nearby, and the visit is planned around it.
When does the report arrive?
Each package has its own report time. Basic is within 48 hours, Standard is 24–48 hours and Premium is the same day. If you have a deadline, such as an exchange date, let us know as you book.
Are you insured?
Professional indemnity and public liability insurance cover our surveys. Ask if you need details for a managing agent or building owner.
Does someone need to be in?
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 when booking.
Is this a RICS survey?
No. It is a specialist roof survey, not a RICS Level 2 or Level 3 building survey. It focuses on the roof and can sit alongside a RICS survey.
How long have you been surveying roofs?
Over 5,000 surveys so far, across 20+ years of surveying roofs, and 98% of clients are satisfied.
What happens if roof problems are left?
For a buyer, the best time to learn about a flat roof is before contracts are exchanged. Once you’ve exchanged, any work on the roof is down to you. A report gives you facts to put to the seller or agent. Many older London roofs have only old felt under the slates, or no underlay at all, so once the slates or flashings let water past, little stops it reaching ceilings. Left alone, that means wet timbers and plaster, which is a far bigger job than the roof fault itself.
Every price we give includes VAT. Flat roof survey starts from £150, including VAT. We confirm the price for the job before booking.

What happens on the day
Photos are taken throughout the visit, so the report shows exactly what we saw. Close-ups come from the safest viewpoint available. Most surveys take about 1–2 hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. In a London area like Walworth, the main things to sort out are parking and access: let us know about parking, the floor the property is on, any shared entrance and loft access. We then look at what can be seen safely from ground level, windows, the loft and, where it is safe, the roof itself.
- We agree the roof to be surveyed, its use and any leaks you know about.
- We look at the roof from ground level, windows and the roof where it’s safe.
- The covering is checked for wear, splits, blisters and standing water.
- We photograph and record the outlets, upstands, trims and rooflights.
- The report, with photos and recommendations, comes to you by email.
How to prepare
- Jot down any questions you want answered
- Have any paperwork from past roof work to hand
