How a flat roof survey works in Dartford
A flat roof survey looks at the covering, the edges, the outlets and the details where the roof meets walls and rooflights. We cover felt, mastic asphalt, EPDM rubber, GRP fibreglass and single-ply roofs. We survey extension, garage and dormer roofs as well as bigger roofs on flats, offices and units. The findings go into a written report with photos, setting out the defects and what we’d recommend. Typical surveys look at upstands pulling away from walls and standing water left after rain, on EPDM rubber, single-ply membranes and GRP fibreglass.
In a town like Dartford, lots of shops, schools and business units have flat roofs. They’re easy to forget until water comes through a ceiling tile, and by then the insulation underneath may be wet. A survey, or electronic testing where the membrane suits it, shows what’s going on. If someone else manages the building, let us know so roof access can be arranged.
With the Standard Survey, you also get moisture detection, a structural check and a follow-up consultation. The Premium Survey goes further, with thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

Why get it checked now?
A leak over an office, shop or unit can affect the people and stock underneath. A planned survey lets you budget for work rather than deal with an emergency around the people who use the building. In a family home in Dartford, a small roof fault lets water into places you can’t see, such as the loft insulation, the top of a wall or the roof timbers. By the time it shows inside, the job has grown.
Price depends partly on the package: Basic from £150, Standard from £250 or Premium from £400, all with VAT included. The roof’s size, height and access matter as well.

When to book a survey in Dartford
Flat roofs swing between hot and cold more than most parts of a building. This constant movement works at laps, seams and board joints, which can open splits and cracks over the years. Older coverings that have lost their flexibility are the most likely to suffer.
We’re often asked to look at:
- Ponding water that does not drain away
- Splits, cracks and crazing
- Water getting in at rooflights
- Raised blisters across the surface
If you look after a building such as Dartford Primary Academy, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
Questions to ask before booking
- Do they have a CAA Flyer ID and Operator ID for drone work?
- What insurance they carry
- Whether the price includes VAT
- What’s outside the scope of the survey
Flat roof surveys around Dartford
Historic houses such as Hall Place and Gardens, about 2.8 miles west, show how far back building in the area around Dartford goes. If your house is among the older ones, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material. Across Kent, older roofs are often handmade clay or peg tiles, and tile-hanging on upper walls is a familiar sight. Kent’s older buildings take in oast houses and timber-framed Wealden hall houses as well. Next to the main roofs there is typically a flat roof somewhere, whether on an extension, a garage or a commercial unit.
If you live in an older home near Church of the Holy Trinity, the joins between later flat roofs and the old walls are where problems typically start. If you look after a shop, office or commercial unit, for instance near Bluewater, outlets and upstands on commercial flat roofs are the places to check before trouble starts.

Your questions about flat roof surveys in Dartford
Is there anything to prepare before you come to Dartford?
Clear the way to the loft hatch if there is one, and let us know about any leaks, stains or past repairs. Let us know about parking and access in Dartford too.
Does a conservation area affect roof work in Dartford?
We cannot confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
Can you inspect my roof with a drone?
Where it helps and it is safe, yes. Whether we can fly on the day depends on the weather and the airspace rules, and we check for restrictions near airports before flying. We’re a CAA-registered drone operator.
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, like old cement sheeting, the report flags them so a specialist asbestos surveyor can check them.
How long does the survey take?
Most surveys take roughly 1–2 hours for a small flat roof at home, and longer for a large commercial one. We will confirm the timing when booking.
Can you tell me how long my flat roof will last?
A precise figure is not something we give, because so much depends on upkeep, exposure and workmanship. Our report describes the condition and what needs doing, and when.
Do you look in the loft space?
Yes, where the survey calls for it and there’s safe access. We look for staining, damp, daylight and signs of movement.
The survey, step by step
There is not much for you to do on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we’ll get on with the inspection. The survey itself takes about 1–2 hours on an ordinary house, while a commercial roof takes nearer three to four hours. A typical visit in Dartford begins with the street side of the roof and then moves round the building. The back garden is frequently where extensions, dormers and rear slopes are best seen, so unlocked gates help. Then, if it can be reached safely, we look in the loft.
- We start with the address and, on larger roofs, the roof area and access.
- We check the rooms or spaces under the roof for staining where there’s 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.
Before we arrive
- Keep pets out of the way during the survey
- Let us know about parking before the day
- Show us where any leaks or stains appear
Arrange a survey
Booking is simple: just ring 07833 053749 or send us an email and give us some details about the property and we’ll suggest the right survey. We confirm the price before anything is booked.
Advice
Before and after the survey
Over many surveys, some simple habits stand out:
- Plan a survey before the covering reaches the end of its usual life
- File the paperwork for the roof and any repairs
- Never stand on rooflights or fragile sheeting
- Look for standing water a day after rain
You can use the report to ask roofers to quote for the same work. Because everyone is pricing the same findings, the quotes are easier to compare. You stay in control of who does the work and when.
Check the roof from a window after a downpour. Water still lying a day or two later is worth getting looked at.
