Common questions in Coldharbour
Do you cover Coldharbour?
Yes. We cover the whole of London and South East England, and Coldharbour is part of that. Just ring 07833 053749 or use the contact form and let us know about the property.
Can parking be tricky for a visit in Coldharbour?
It depends on the street. Where there are permit zones, a visitor permit or nearby pay-and-display bay works well, and a driveway is even better.
Can you survey a shared roof?
Yes, once access has been agreed. The roof of a block or converted house is frequently shared, so we need permission from the freeholder or managing agent. We inspect only the parts we’re allowed to reach.
How quickly is the report sent?
It depends on the package: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. Reports are sent by email.
How long have you been surveying roofs?
Over 5,000 surveys so far, over more than 20 years.
Can you test old roof sheets for asbestos?
Asbestos testing is not part of our survey. Where a roof has materials that might contain asbestos, such as old cement sheeting, the report flags them and recommend a specialist asbestos surveyor.
Do I have to be there for the survey?
If the survey includes the loft or the inside of the building, someone needs to let us in. Access is agreed with you when you book.
How a flat roof survey works in Coldharbour
Ponding is frequently the first sign that something on a flat roof is not right. It can mean the falls were never right, an outlet is blocked or the deck has started to sag. The survey notes any ponding, the state of each outlet and any dips that hint at a sagging deck. Where the deck may be a structural issue, our report says a structural engineer should look at it. We are often asked to look into standing water left after rain and signs of deflection in the roof deck, across GRP fibreglass, upstands and outlets and single-ply membranes.
Across London, flat roofs are everywhere, from back additions and dormers to roof terraces, blocks of flats and offices. Coverings range from felt and asphalt to EPDM rubber, GRP fibreglass and single-ply membranes, each with its own weak points. Which one is on a roof in Coldharbour shapes how it’s checked. Older flat roofs are often felt or asphalt, newer ones rubber or GRP.
The report works through the roof section by section, from the main slopes down to the gutters and outlets. You will see the good as well as the bad.

Checking the roof from ground level
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it.
A DIY look is useful, but it isn’t a survey. You won’t see flashings, valleys or the backs of chimneys properly from the ground, and those are details a survey looks at closely.
Landlords, agents and block managers in Coldharbour
Freeholders and residents’ companies use a roof report to plan and budget, with the most urgent items set out first.
Managing agents and residents’ management companies use roof surveys to plan maintenance. The report sets out what needs attention now and what can wait, which helps with budgets and planning.
What we are asked to look at in Coldharbour
The surface of a flat roof heats up and cools down far more than the rooms below. This constant movement works at laps, seams and board joints, and in time it can open up splits and cracks. Coverings that have hardened with age tend to suffer most.
Typical things we are asked to look at include:
- Ponding water that doesn’t drain away
- Cracked or split membrane
- Outlets choked with leaves and silt
- Leaks around rooflights
Controlled parking zones are common in London, so mention any permit rules for Coldharbour.
What to check before booking
- Their drone registration, if they fly one
- How long the report takes to arrive
- Will the report include photos?
- Which viewpoints they use to see the roof
Why get it checked now?
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. Finding the cause now keeps more options open. Blocked gutters and hoppers on London houses overflow and soak brickwork, which can lead to damp inside. A blocked outlet ignored for a winter or two can mean damp walls inside.
Bigger, taller and commercial roofs take more time to survey, so they’re priced to match. You’ll know the figure before booking.
Why us?
- A sub-250g drone, flown with a CAA Flyer ID and Operator ID
- An independent view of the roof
- Surveys seven days a week
- Thermal imaging and drones used where they help

Flat roof surveys around Coldharbour
Historic houses like Eltham Palace, about 1.1 miles north, show how far back building in the area around Coldharbour goes. Older homes in the wider area frequently have features worth a closer look, such as 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. 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. Bay roofs, hip ridges and dormers from later loft conversions are the details that set these houses apart. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
Take a building like Mottingham Primary School: ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. If you live in an older home near St Alban, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.

The survey, step by step
After the inspection, everything we found is written up as a written report with photographs, sent to you by email. On timing, it usually takes between one and two hours for a house, and about three to four hours for a commercial roof. In Coldharbour, visits are available on weekdays and at weekends. It helps if you can point us to a visitor permit or a nearby bay. Upstairs rooms at the back are useful too, as they frequently give the best view of a rear addition.
- You send us the address and, for commercial roofs, an idea of the roof’s size.
- We check the rooms or spaces under the roof for staining where there is access.
- The roof is inspected from every safe viewpoint, without walking on fragile surfaces.
- We record every defect with a photo and its likely cause.
- The report explains the condition and recommends what to do first.
How to prepare

- Find any records of previous roof work
- Buyers: confirm access with the estate agent or seller
