What we look for on each type of roof
GRP fibreglass
A GRP fibreglass roof is a hard, resin-bonded surface over a timber deck. The survey checks for cracking at board joints, at the edge trims and where the roof meets walls.
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.
Flat roof survey in Addington
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 note any sign that the deck below has got wet. That way, defects are found before they reach the room below. If you’ve noticed edge trims that have lifted or split and dips that suggest the deck is deflecting, a survey will tell you what’s going on, on GRP fibreglass, mastic asphalt and single-ply membranes alike.
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 Addington, the roof above may belong to the building rather than one flat.
Pictures do a lot of the work in our reports, so you can see each defect rather than just read about it. Anything out of sight on the day is listed as such.

Signs you need a flat roof survey in Addington
No flat roof covering lasts for ever. Around 15 to 20 years is common for felt, while EPDM frequently lasts 30 to 50 years and GRP up to about 30, although how well it was laid and looked after matters a great deal. We can tell you how your roof is doing, whatever its age.
We are often asked to look at:
- Cracked or split membrane
- Pools of water lying on the roof
- Raised blisters across the surface
- Upstands pulling away from walls
Take a building like Applegarth Academy: ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
What to check before booking
- Whether the roof space is looked at, where there is one
- Their insurance cover
- Whether VAT is added on top
- Which limits apply to the survey
Should I look at the roof myself first?
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.
A lot can be seen from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.

If you can, have these to hand when you get in touch:
- Why you want a survey: buying, a leak, a storm or new work
- The type of building and roof, like pitched or flat
- Access details, like a loft hatch or a shared roof
- Where the property is, with the postcode

Landlords, agents and block managers in Addington
If the property is let, the agent or a tenant can let us in. Surveys run on any day of the week, which can make access easier.
Where a roof is shared: access has to be agreed with whoever owns or manages the building. Tell us about it when booking and we’ll plan the visit with that in mind.
Common questions in Addington
Do you cover Addington?
We do. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
Is my home in Addington listed or in a conservation area?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. It matters most if you’re planning to re-roof in a different material.
Can you inspect my roof with a drone?
Yes, where it applies and safe. We’re a CAA-registered drone operator (Flyer ID and Operator ID), flying a sub-250g drone. It’s included in the Drone Roof Survey and, where it applies, the Premium Survey.
What insurance do you have?
We are covered by professional indemnity and public liability insurance.
Can you find where water is getting through my flat roof?
We check the whole roof, since water can travel before it shows inside. Every split, lap, upstand, outlet and rooflight we can see is looked at. Where nothing visible explains the leak, the report says what to try next.
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. Fragile surfaces are never walked on.
When does the report arrive?
Each package has its own report time. Basic: within 48 hours. Standard: 24 to 48 hours. Premium: the same day. If you have a deadline, like an exchange date, let us know when booking.
How it works
Expect us to ask a few questions before we start, about the roof’s history, any leaks and past repairs. Then the inspection itself takes about 1–2 hours for most houses, with bigger or more complicated roofs taking longer. In Addington, as in much of London, a good many properties are flats or terraces without side access, so the back of the roof is often seen from upstairs windows, from inside or, where a flight is allowed, from the air. Mention any building rules, key holders or managing agents as you book.
- 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.
- A written report with photos and recommendations is emailed to you.
Before the survey
- Find any records of previous roof work
- Clear the way to the loft hatch
- If you are buying, let the agent know when we’re coming
Getting a price

What a flat roof survey looks like in Addington
Further from the centre, London’s housing takes in interwar semis with hipped roofs in clay or concrete tiles as well as slate-roofed terraces. If your home in Addington is one of them, bay roofs, hips and later dormers each have their own details. Next to the main roofs there is usually a flat roof somewhere, whether on an extension, a garage or a commercial unit. The wider area around Addington has a long history of building, with Addington Palace about 0.4 miles west. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and the council can say whether a home is in a conservation area.
If you own a rental within reach of West Wickham station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. For businesses in and around places such as St George's Walk, the flat roofs over shops and commercial units are worth checking before a leak, not after.
