How a flat roof survey works in Darenth
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. The surface, the falls, the upstands and the trims are all looked at closely, and we look for signs that water has reached the deck. The aim is to find problems before they show up as a stain on a ceiling. We survey felt flat roofs, EPDM rubber and mastic asphalt, and people most often book us about blisters and bubbles in the covering and cracked or split membrane.
Some older homes in villages like Darenth are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. If you’re planning work, check with the council first. Finding out what state the roof is in gives you the facts to plan with. Changes that affect a listed building’s special interest need listed building consent.
We keep jargon out of it: if work is needed, the report says so clearly.

Why act early in Darenth
A small split in a flat roof is usually a modest job when it is found early. Left alone, water can soak the insulation and the deck, and the job grows. A survey now shows which you’re dealing with. Outbuildings and barns around Darenth are easy to forget, but a failed roof there can spoil what’s stored inside. A quick look before winter can save a lot.
What a survey costs comes down to the roof itself: its size, its height, how many sections it has and how it can be reached and seen safely. Flat roof survey starts from £150, including VAT.

Landlords, agents and block managers in Darenth

A roof problem in a let property affects your tenants as well as the building. A survey helps you spot issues early and plan the work around your tenants.
Roof by roof
Mastic asphalt
Asphalt has no laps, so its weak points are cracks and the skirtings at walls and upstands. Our report notes crazing, cracks and any likely entry points.
GRP fibreglass
Movement in the deck or a thin layer of resin can lead to cracks in GRP. We record any cracking and any signs of the deck moving.
Do you need a flat roof survey in Darenth?
Every flat roof covering has a working life. Felt roofs often last around 15 to 20 years, EPDM frequently 30 to 50 years and GRP up to about 30, although how well it was laid and looked after matters a great deal. A survey shows how yours is holding up, whatever its age.
Most people get in touch after spotting one of these:
- Cracked or split membrane
- Leaks around rooflights
- Standing water left after rain
- Blistering in felt or asphalt
For an older house near a landmark such as Church of St Margaret of Antioch, flat-roofed rear additions and dormers added over the years are worth checking.
Choosing a roof surveyor
- Are they insured for the work?
- What exactly goes into their report
- Whether VAT is added on top
- If they fly a drone, whether they hold a CAA Flyer ID and Operator ID

Darenth: your questions answered
Do you cover Darenth?
Yes, Darenth is one of the places we work. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
How do I find out if my home in Darenth is listed?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Do you carry out surveys on Saturdays and Sundays?
Visits run seven days a week in the daytime. Just say which days work for you.
What does the report include?
It works through the roof part by part, in writing and with photos, and ends with what we recommend. Points are put by urgency where it matters.
Will the survey show why my flat roof is leaking?
The survey covers the covering and all the details where leaks usually begin, recording anything that could let water through. Where the source isn’t obvious, a roof leak investigation or electronic leak detection may be the next step.
What insurance do you have?
We are covered by professional indemnity and public liability insurance, for every survey we carry out.
What do I do with the report?
The report arrives by email, with photos and clear recommendations. The Standard Survey includes a follow-up consultation, and the Premium Survey an in-person consultation.
Flat roof surveys around Darenth
The wider area around Darenth has a long history of building, with Hall Place and Gardens about 4.6 miles north-west. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and the council can say whether a home is in a conservation area. Handmade clay tiles, including Kent peg tiles hung on pegs through two holes, are typical of older Kent buildings. You will also find oast houses and timber-framed Wealden hall houses among the county’s older buildings. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises.
If you own a rental within reach of Farningham Road station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. If you look after a shop, office or commercial unit, for example near Bluewater, outlets and upstands on commercial flat roofs are the places to check before trouble starts.

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. Send it with your enquiry and it will help the survey.
Watch the gutters in a downpour, from a window or the ground. Overflowing water can point to a blockage or a sagging run.
How it works
On the day, we start by asking what you’ve noticed and what you want to find out. After that, we check everything we can see safely, from the ground, from windows, in the loft space and by drone where it applies. Most surveys take an hour or two for a house, though large, tall or awkward roofs take more time. In a small place like Darenth, access is normally the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- First you give us the address, what the roof covers and any leaks you’ve noticed.
- 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 checked: covering, falls, upstands, outlets, trims and rooflights.
- We check the rooms or spaces under the roof for staining where we can reach them.
- We send a written report with photos, the defects we found and what we recommend.
Preparing for the visit
- Show us where any leaks or stains appear
- Jot down any questions you want answered
- Gather any invoices or paperwork from past roof work
