Leavesden Flat Roof Survey

Why it’s worth a survey now in Leavesden
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. Around Leavesden, leaves and moss in gutters lead to overflowing water and damp walls, especially where trees overhang. Dealing with the cause is simple; drying out a wall is not.
Our price is from £150, including VAT. What you pay depends on how big and how high the roof is, access and which survey you book.
Why book with us
- Independent findings on the roof’s condition
- Packages from £150, inc. VAT

Flat roof survey in Leavesden
Buying a home with a flat-roofed extension, dormer or garage? It helps to know that roof’s condition before you exchange. Many felt roofs need renewing after around 15 to 20 years, and EPDM and GRP often go on for longer. Our report records the covering, how it’s holding up and any defects we can see, with a photo of every defect. You then have something specific to put to the seller or agent. Typical surveys look at raised blisters across the surface and damaged trims at the roof edge, on felt flat roofs, upstands and outlets and GRP fibreglass.
In a smaller place like Leavesden, some flat roofs sit in the open, where wind can catch loose edges and trims. Sun on a flat roof also ages felt and bitumen. Splits, blisters and lifting edges are what to look out for, along with water that sits after rain. A flat roof that still holds water days after rain is also worth a closer look.
How fast the report arrives depends on the package: the Basic Survey within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey on the same day.

Questions from Leavesden
Is Leavesden within the area you cover?
We do. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Do you carry out roof surveys in Leavesden?
We do. The survey and report are the same in Leavesden as anywhere else.
What will the report tell me?
It sets out what we found, why it matters and what we recommend, with photographs throughout. It also says if any part of the roof couldn’t be seen safely.
Is ponding on a flat roof a problem?
Standing water a day or two after rain typically needs attention. The cause may be the outlets, the falls or the deck. We check each of these and record what we find.
Does the survey cover 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 you survey roofs on blocks of flats?
Yes, once whoever controls the roof agrees access. We check the parts we’re given access to.
Do you use drones?
Yes, where it applies and safe. We fly a sub-250g drone and we’re a CAA-registered drone operator (Flyer ID and Operator ID). It’s included in the Drone Roof Survey and, where applicable, the Premium Survey.
For landlords and managing agents
Landlords and letting agents in Leavesden book surveys as well as homeowners. The report gives you a dated record of the flat roof, with photographs.
Roof problems in a rented home affect tenants as well as the building. A survey shows what needs attention, so you can plan the work.
Tips that help
Over many surveys, some simple habits stand out:
- Ask contractors to protect the roof if they work on it
- File the paperwork for the roof and any repairs
- Make sure new fixings through the roof are properly sealed
- Check the outlets after the leaves fall
You can use the report to ask roofers to quote for the same work. With each roofer working from the same list, comparing quotes is simpler. It’s your choice who carries out the work and when.
Small defects are simpler to deal with while they’re still small. A flat roof that’s looked after between surveys usually lasts longer.
What we do, step by step
There is not much for you to do on the day. Show us any stains, drips or problem areas you know about, and we’ll get on with the inspection. A typical survey takes an hour or two for a small flat roof at home, and longer for a large commercial one. Parking around Leavesden is normally easier than in a town centre, but mention lanes, gates or long drives. Low roofs on bungalows can often be seen well from the ground, and the loft shows the rest.
- 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.
Preparing for the visit
- Clear the way to the loft hatch
- Unlock side gates and any roof access doors
- Agree roof access with the managing agent if it is shared

What we look for on each type of roof
EPDM rubber
EPDM is a synthetic rubber membrane, often laid in a single sheet on smaller roofs. We check the laps, the edges, the corners and any punctures.
GRP fibreglass
A well-laid GRP roof frequently lasts up to about 30 years. Cracking where boards meet or where the deck moves is a common early sign of trouble.
Common roof problems in Leavesden
Flat roofs swing between hot and cold more than most parts of a building. That movement pulls at seams, laps and the joints between boards, and in time it can open up splits and cracks. Older coverings that have lost their flexibility are the most likely to suffer.
It is worth booking a survey if you’ve seen:
- Damaged trims at the roof edge
- A sagging deck under the covering
- Ponding water that does not drain away
- Outlets choked with leaves and silt
If you run a business near Charter Place, a flat roof over a business is out of sight and out of mind until it leaks.

What a flat roof survey looks like in Leavesden
In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, with flat-roofed extensions, dormers and garages common everywhere. Flat roofs fill the gaps in between, on extensions, garages, dormers and business premises. High Elms Manor, about 0.4 miles north-east, is one of the historic houses in the wider area around Leavesden. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and any change of roofing material on a listed home needs checking with the council first.
Landlords with a home close to Garston station may find that the flat roof over a let home is worth a look before it becomes a tenant complaint. Take an older house close to Church of All Saints: later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear.
