How a pre-purchase roof survey works in South Mimms
We survey roofs for buyers in South Mimms and across London and South East England. Whether it’s a terrace, a semi, a detached house or a flat, we follow the same careful process. The report says what’s in good order, what isn’t and what to deal with first. We hold professional indemnity and public liability insurance, and have 20+ years’ experience. To book, call 07833 053749 or send us an email. Typical surveys look at roof slopes that look uneven or sagging and blocked or leaking gutters, across gutters and downpipes, natural slate and lead flashings and valleys.
Somewhere as small as South Mimms, older cottages, farmhouses and converted buildings often sit beside a few newer homes. Village roofs can be clay tile, slate, stone or even thatch on some older buildings. Whether you are buying or have just had a roof replaced, each material has its own checks. Older roofs may also have old felt underlay or none, and fixings that have done a long stint.
The written findings come by email, easy to pass on to a roofer, an agent or an insurer. Turnaround is within 48 hours for Basic, 24–48 hours for Standard and same day for Premium.

Why it is worth a survey now in South Mimms
After exchange, any roof defect is yours to deal with. Before then, you can still ask questions, ask for work to be done or reconsider. A survey after you’ve moved in tells you the same things, but with far less room to act on them. Outbuildings and barns around South Mimms are easy to forget, but a failed roof there can spoil what’s stored inside. It is worth including them in a survey before a winter does the damage.
To find out what your survey will cost, call 07833 053749 or drop us an email and let us know about the roof. We’ll confirm the figure before booking.

DIY checks: what’s safe
After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Don’t go up yourself.
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.
Signs you need a pre-purchase roof survey in South Mimms
Flat roofs turn up on extensions, dormers, porches and garages. A felt roof often lasts around 15 to 20 years, and ponding, blisters and splits are common signs of age. They’re easy to overlook on a viewing, because many can only be seen from an upstairs window.
People usually book a survey after spotting something like this:
- A ridge or slope that dips
- Lead that has worked loose at a wall or chimney
- Old water stains in the loft space
- Chimney mortar that has eroded
If you let a flat or house near Potters Bar station, a survey before purchase, or before signing off a new roof, saves surprises once a tenant moves in.
Choosing a roof surveyor
- Which limits apply to the survey
- How much experience they have with roofs like yours
- What follow-up you get after the report
- Which parts of the roof they’ll actually see
The survey, step by step
The visit usually starts outside and finishes in the loft: outside views come first, then the loft space if there is safe access. All told, expect about 1–2 hours for most houses, while a commercial roof takes nearer three to four hours. For a village or hamlet like South Mimms, the journey is planned ahead of time: let us know about narrow lanes, gates, long drives and where we can park. On the day, we inspect everything that’s safely in view, inside and out.
- You get in touch after your offer is agreed, with the address and your target exchange date.
- Access is arranged through you, the agent or the seller.
- We check the roof from ground level, from windows, from the roof space and from the roof where safe.
- Coverings, ridges, valleys, flashings, chimneys and gutters are checked and photographed.
- We email a report with photos and recommendations, ready for you to use before exchange.
How to prepare
- Tell us about any leaks, stains or damp patches you know of
- Make a note of anything you’d like us to look at
- Move anything stored under the loft hatch
Booking a survey
Every survey is priced before it’s booked, so you know the cost up front. Our price is from £150, including VAT. For a price for your roof, call 07833 053749 or email us.
Advice
What we look for on each type of roof
Natural slate
Slate is common on Victorian and Edwardian houses. We check for slipped, cracked and missing slates, plus the metal clips that show earlier patching.
Flat roofs
A flat roof that has been coated over several times may hide problems underneath. We say when the covering would need opening up to know more.
Buying a home or a new roof in South Mimms
Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles, and flat-roofed additions turn up almost everywhere. Whether you are buying or checking new roofing work, knowing the materials helps make sense of what the inspection finds. If your survey includes the drone, the flight is checked against the Drone Safety Map first.
Wyllyotts Manor lies about 1.6 miles east, so building around South Mimms goes back a long way. If you’re buying an older home nearby, it is worth knowing whether it is listed or in a conservation area before you plan any re-roofing. For an older house near a landmark like Church of St Giles, ask the seller about past roof repairs, because older roofs frequently have patched valleys, replaced slates and reset ridges.

Common questions in South Mimms
Is my home in South Mimms listed or in a conservation area?
For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.
Is South Mimms within the area you cover?
Yes, we do. Our area covers London and South East England, and smaller places are part of that. The journey is planned ahead, so it’s useful to know about access.
Will you fly a drone over my roof?
Yes, where it is applicable. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and every flight depends on the airspace and the weather.
How long does a pre-purchase roof survey take?
It normally takes roughly 1–2 hours on an ordinary house, and longer for a large or complex roof. The report follows within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium.
Do you test for asbestos?
No. Asbestos surveys and testing aren’t part of what we do. We flag materials that could contain asbestos, such as cement sheets or soffits on pre-2000 buildings and suggest a specialist asbestos surveyor checks them before any work.
When will the report arrive?
It depends on the package: within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium. Tell us your exchange date and we will help you choose.
Are you insured?
We are covered by professional indemnity and public liability insurance, for every survey we carry out.
Tips from our surveys
Over many surveys, some simple habits stand out:
- Give your solicitor a copy of the report
- Ask the seller about past roof repairs
- Let us know your timetable
- Don’t leave it until just before exchange
The Standard Survey includes a follow-up consultation to talk the findings through, while Premium includes a consultation in person. Whichever package you choose, you can ask us what a finding means.
After strong winds, look at the roof from ground level. Pieces of slate or tile in the garden mean something has moved. Dealing with them early keeps water out.
