- Splits, cracks and crazing

- Damaged trims at the roof edge
How a flat roof survey works in Osidge
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. Single-ply PVC and TPO roofs are checked at their welds, edges and fixings. Knowing what you have and how it’s doing helps you plan what comes next. Common reasons to book are splits and cracks in the covering and blocked or damaged outlets, on mastic asphalt, single-ply membranes and felt flat roofs.
On a London roof terrace or a flat roof over a back addition, water often 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 Osidge, the roof above may belong to the building rather than one flat.
The Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

Local flat roofs in Osidge
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. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops. Bruce Castle, about 3.8 miles south-east, is one of the historic houses in the wider area around Osidge. Older homes in the wider area often have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material.
If you let a flat or house near Oakleigh Park station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. If you live in an older home near St Andrew'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. For a London address like Osidge, it helps to know about controlled parking before the day.

What else we do in Osidge
How it works
When we arrive, we start by asking what you’ve noticed and what you’d like to know. After that, we check everything we can see safely, from the ground, from windows, in the roof space and by drone where it applies. The survey normally takes between one and two hours for a small flat roof at home, and longer for a large commercial one. In Osidge, visits are available on weekdays and at weekends. London parking is often by permit or pay-and-display, so it is useful to know what’s near you. A back bedroom window can be the best vantage point for a rear addition, so we may ask to use one.
- First you give us the address, what the roof covers and any leaks you’ve noticed.
- We look at the roof from wherever it can be seen safely.
- 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.
- We send a written report with photos, the defects we found and what we recommend.
Getting ready for the survey
- Have any questions written down, so nothing gets missed
- For a flat or shared roof, check access with the building owner or managing agent
- Clear the way to the loft hatch

Related advice
Why act early in Osidge
Ponding seldom gets better on its own. It usually points to an outlet, the falls or a sagging deck, and every wet spell adds to the wear. Knowing the cause early gives you more choice over what to do. 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. Dealing with it early is far less disruptive.
Prices quoted always include VAT, and the written report is part of the package. Prices start from £150, including VAT. Where your roof sits in the range depends on its size, height and access.

Common questions in Osidge
Do you cover Osidge?
Yes, Osidge is one of the places we work. The survey and report are the same in Osidge as anywhere else, and visits run on weekdays and weekends.
Will parking be an issue for a roof survey in Osidge?
Usually it’s manageable with a little notice. Tell us what parking is available nearby, and the visit is planned around it.
What types of flat roof do you survey?
We cover the main flat roof coverings: felt, asphalt, EPDM, GRP and single-ply. We record what the covering is and how it’s holding up.
Can you inspect my roof with a drone?
Where it helps and the rules allow, yes. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and every flight depends on the airspace and the weather.
What will the report tell me?
It works through the roof part by part, in writing and with photos. The most urgent items are made clear.
Do you survey roofs on blocks of flats?
Yes, as long as access is agreed. Roofs over flats are frequently shared, so the freeholder or managing agent needs to agree access. We inspect only the parts we’re allowed to reach.
What does ponding on a flat roof mean?
Water that lies on a flat roof for days is a sign that something needs attention. The cause may be the outlets, the falls or the deck. We check each of these and record what we find.
Practical tips
These tips come from what we see on roofs every week, before and after a survey:
- Clear roof outlets and gutters each autumn
- Keep clear of rooflights and fragile roof sheets
- 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
If you are buying, the report gives you something specific to take back to the seller or agent. You might ask for work to be done before completion, or discuss the price, depending on what we found.
After heavy rain, look at the roof from an upstairs window if you can. Water still lying a day or two later is worth getting looked at.
Rented homes, blocks and businesses
Where a roof is shared: access has to be agreed with whoever owns or manages the building. Mention it when you get in touch and we will plan the visit with that in mind.
Landlords, agents and building managers in Osidge and across Greater London can book any of our surveys. To discuss a property or a block, ring 07833 053749 or send us an email.
Different roofs, different checks
EPDM rubber
Lifting at the edges and loose areas of membrane are common EPDM problems. Any we find are noted and photographed.
Mastic asphalt
Mastic asphalt is a heavy, seamless covering often found on older blocks, balconies and commercial roofs. The survey checks for crazing, cracking, blistering and splits where the asphalt turns up the walls.
Checking the roof from the ground
It’s useful to keep a record: dates of leaks, photos from ground level and any work done on the roof. Share it with us as you book, as it helps us focus the survey.
If you have a loft with safe access, take a look inside. Take a torch and only step on boards or joists, and look for staining, damp timber or daylight coming through.
