Flat Roof Survey in Lewisham
Flat roof surveys across Lewisham, with over 20 years’ experience behind it. Every survey ends with a written report and photographs.

Common roof problems in Lewisham
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. Fixings added through the covering often start leaks too.
Most people get in touch when they’ve noticed one of these:
- Splits, cracks and crazing
- Blocked or damaged outlets
- Loose or cracked edge trims
- Dips that suggest the deck is deflecting
Queen's House, about 1.4 miles north, is one of the historic houses in the wider area around Lewisham. If your home is older, its flat-roofed extension or dormer may be on its second or third covering.

Flat roof survey in Lewisham
Ponding is frequently the first sign that something on a flat roof is not right. 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 will recommend a structural engineer. We survey mastic asphalt, EPDM rubber and single-ply membranes, and people most often book us about cracked or split membrane and failed seals around rooflight kerbs.
Offices, shops and blocks of flats across London often have large flat roofs with plant, rooflights and walkways. Each pipe, upstand and fixing through the covering is a possible weak point. In Lewisham, roof access is agreed with the building manager or owner beforehand. Plant bases, rooflights and cable entries are all places where water can get in.
If any part of the flat roof couldn’t be seen safely, we say so in the report. You’ll know exactly what was inspected and what wasn’t, and what we’d suggest next.

Prices for flat roof surveys in Lewisham
When we price a survey, we consider:
- Features like valleys, chimneys, dormers and parapets
- Basic, Standard or Premium
- The number of roofs, including extensions and garages
- House, block, shop or office
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. The price is confirmed before you book.

Questions from Lewisham
Does a conservation area affect roof work in Lewisham?
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, and councils can also use Article 4 directions.
Can parking be tricky for a visit in Lewisham?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot.
What does the report include?
It explains what we saw, what it means and what we’d suggest, backed by photographs. Anything we couldn’t see safely is noted too, so you know exactly what was covered.
How soon will I get the report?
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, like an exchange date, let us know when you book.
Can you survey any kind of flat roof?
Felt, mastic asphalt, EPDM rubber, GRP fibreglass and single-ply membranes are all part of the work. The report names the covering and explains its condition.
What happens after the survey?
The report comes by email, and you decide the next step: raise it with a seller, send it to an insurer, brief a roofer or share it with a managing agent.
Can you survey in bad weather?
Light rain is typically fine; heavy rain and wind are different. Strong wind or heavy rain can make access unsafe and ground a drone, and we’d agree another day.

What we look for on each type of roof
GRP fibreglass
GRP can crack if the deck beneath flexes or if the resin was laid too thin. We record any cracking and any signs of the deck moving.
EPDM rubber
EPDM is a synthetic rubber membrane, frequently laid in a single sheet on smaller roofs. We check the laps, the edges, the corners and any punctures.
Can I check my roof myself?
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.
It helps to keep a record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry, as it helps us focus the survey.
What we do, step by step
Where it is relevant and can be reached safely, the roof space is checked as well as the outside. Inside, we look for staining, damp, gaps and signs of movement, as far as the space allows. The whole visit usually takes roughly 1–2 hours at a typical home, with bigger or more complicated roofs taking longer. In Lewisham, visits are available on weekdays and at weekends. London parking is frequently by permit or pay-and-display, so it helps to know what’s near you, 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.
- We start with the details: the address, the roof’s use and any leaks or stains.
- The roof is inspected from safe viewpoints, and from the roof itself where that is safe.
- Every part of the roof we can see is looked at: covering, falls, upstands, outlets, trims and rooflights.
- Inside, we look for damp and staining under the roof where there is access.
- We send a written report with photos, the defects we found and what we recommend.
Getting ready for the survey
- Let us know about parking near the property
- For flats, check roof access has been agreed
- Make a note of anything you’d like us to look at

Flat roof surveys in Lewisham: local notes
Lewisham has a number of hotels within about a mile and a half, and hotels, like offices and blocks of flats, often have flat roofs. For hotels and other commercial buildings, finding the cause of a flat roof leak quickly keeps rooms in use. Welsh slate on Victorian and Edwardian terraces is a familiar sight across inner London. Behind many of their parapets sit butterfly roofs and valley gutters that cannot be seen from the pavement. Shared chimney stacks, party-wall upstands and lead work come with this kind of house. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
If you run a hotel or guest house in or near Lewisham, a roof problem can mean rooms out of use, so it pays to find faults before guests do. Take an older house close to St Stephen's Church: any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

Before and after the survey
These tips come from what we see on roofs every week, before and after a survey:
- Keep people off the roof unless they need to be there
- Keep clear of rooflights and fragile roof sheets
- Clear roof outlets and gutters each autumn
- Note any new marks on ceilings beneath the roof
If anything in the report isn’t clear, just ask us. The Standard Survey includes a follow-up consultation and the Premium Survey an in-person consultation, giving you a chance to go through what we found.
After heavy rain, look at the roof from an upstairs window if you can. If water is still there a day or two later, have it checked.
