Pre-purchase roof survey in Amwell
A roof report gives you something solid to take back to the seller or the agent. You can ask about the roof’s history, ask for repairs before completion or rethink the price. We can’t say how a seller will respond, but you will be negotiating from a clear picture rather than a hunch. It can also help you decide whether the purchase is still right for you. We survey flat-roofed extensions and dormers, chimney stacks and lead flashings and valleys, and the problems we’re asked to look at most are gutters choked with leaves and moss and lead that has worked loose at a wall or chimney.
In a village or hamlet like Amwell, homes are frequently older cottages and farmhouses alongside a few newer houses. Village roofs can be clay tile, slate, stone or even thatch on some older buildings. Each covering has its own weak points, whether the roof is old or newly laid. What’s under the coverings, from old felt to the battens and nails, matters too.
The written findings come by email, ready to forward to whoever needs them. Basic reports come within 48 hours, Standard within 24–48 hours and Premium on the day.

Pre-purchase roof surveys around Amwell
Where the drone is part of the survey, the flight is checked against the Drone Safety Map first. Childwickbury Manor, about 2.6 miles south-west, is one of the historic houses in the wider area around Amwell. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first.
If you let a flat or house near Harpenden station, a survey before purchase, or before signing off a new roof, saves surprises once a tenant moves in.

Amwell questions
How do I find out if my home in Amwell is listed?
Historic England’s list shows listed buildings, and the local council can tell you about conservation areas. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Will you come out to Amwell?
Yes. Amwell is within the area we cover, which takes in towns, villages and rural addresses. We survey roofs across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you survey a shared roof?
Yes. Shared roofs just need a little more planning, with the building owner or managing agent. Tell us about it as you book and we’ll explain what’s needed.
Is this the same as a RICS Level 2 or Level 3 survey?
No. It is a roof survey by an experienced roof surveyor, and you get a written report with photos. It doesn’t cover the rest of the property, which a RICS survey does.
When is the best time to have the roof checked when buying?
Book as soon as your offer is agreed. You need the report before you exchange, while you can still ask questions and negotiate.
Is this an asbestos survey?
No. We don’t carry out asbestos surveys or testing. If we see materials that could contain asbestos, such as cement roof sheets or soffits on buildings from before 2000, we flag them and suggest a specialist asbestos surveyor checks them before any work.
When will the report arrive?
That depends on which survey you choose: Basic within 48 hours, Standard within 24 to 48 hours and Premium the same day. Let us know your timetable as you book.
How the survey changes by roof type
Flat roofs
Many homes have a flat roof somewhere, frequently over an extension. Felt roofs often last around 15 to 20 years, rubber longer and GRP up to about 30. We check how the covering is wearing.
Clay and concrete tiles
Many post-war houses have concrete interlocking tiles. They’re heavy and hard-wearing, but they weather and can crack, and low-pitched roofs need their laps to be right.
Should I look at the roof myself first?
Fresh stains on ceilings or walls after rain are worth noting. Photograph them and note the date, as it helps a surveyor trace the cause.
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.
How the survey works
After the inspection, everything we found is written up in a report with photographs, sent to you by email. As for time on site, most surveys take about 1–2 hours at the house you’re buying, depending on its size and how much of the roof can be seen. Cottages and farmhouses around Amwell often have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints.
- Once your offer is accepted, you let us know the address and when you hope to exchange.
- We arrange access with you, the agent or the seller, including the loft.
- We start outside, looking at the roof from ground level and from vantage points.
- We then look from upstairs windows and inside the loft where it is safe.
- You get a written report with photos and recommendations before you exchange.
Preparing for the visit
- Have any questions written down, so nothing gets missed
- Agree roof access with the managing agent if it is shared
- Keep pets out of the way during the survey
How to book

Related advice
Leave it or get it looked at?
The lender’s valuation is done for the lender, not for you. It looks at whether the property is suitable security for the loan, and it will not look closely at the roof. A roof survey is carried out for the buyer, and the report is written for you to use. For an older or listed building in a place like Amwell, repairs may need matching materials and consent, so a defect found early gives time to plan the work properly.
Pre-purchase roof survey starts from £150, including VAT. Packages run from Basic at £150 through Standard at £250 to Premium at £400, inc. VAT.

Tips from our surveys
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Ask who repairs the roof under the lease
- Ask whether there are papers for past roof work
- Book once your offer is accepted
- Notice patches of new decoration in top-floor rooms
If the report shows work is needed, you can raise it with the seller or agent. You might ask for the work to be done before completion, or ask to adjust the price. The outcome is between you and the seller.
After you move in, have leaves and moss cleared from gutters and valleys, ideally once the leaves have dropped. Overflowing water is behind a lot of damp. Get a professional in rather than climbing up yourself.
Signs you need a pre-purchase roof survey in Amwell
Chimneys take the worst of the weather and they’re often the least maintained part of a roof. Pointing crumbles, flaunching cracks and flashings lift. On terraced and semi-detached homes, a stack may be shared with next door, which can affect how any work is arranged.
Look out for signs like these:
- Flashings that have lifted or split
- Blocked or leaking gutters
- Chimney mortar that has eroded
- Slates or tiles that have slipped or gone
Take an older house close to St Helen's Church: ask the seller about past roof repairs, because older roofs frequently have patched valleys, replaced slates and reset ridges.
