- Structural calculations (that’s a structural engineer’s job)

How a pre-purchase roof survey works in Welham Green
The roof is one of the most expensive parts of a home to repair, and one of the hardest for a buyer to see. A pre-purchase roof survey looks at it closely before you are tied in. We check the coverings, ridges, valleys, flashings, chimneys and gutters, and the roof space where it is safe to get in. You get a report with photographs. If you are worried about damp timbers or stains in the loft and loose pots and cracked flaunching, a survey will tell you what’s going on.
In a smaller place like Welham Green, some houses face open ground, so their roofs may take more wind and driving rain. Ridges, verges and flashings are where that weather usually shows first. Whether you’re buying or signing off new work, those edges deserve a proper look. On an exposed roof, a loose ridge or verge soon becomes a bigger job.
Report times depend on the survey you book: the Basic Survey within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey on the same day.

Signs you need a pre-purchase roof survey in Welham Green
Slates and tiles can outlast the nails, battens and underlay that hold them. Natural slate can last 100 years or more, but corroded nails let slates slip. That kind of wear is common on older roofs.
A survey can pick up problems like:
- Loose pots and cracked flaunching
- Flashings that have lifted or split
- Sagging ridge lines or uneven roof slopes
- Signs of past leaks inside the loft
Landlords with a home close to Welham Green station may find that it is worth knowing a roof’s condition before you buy it, or before you sign off new roofing work on it.
Questions to ask before booking
- Their track record with similar roofs
- Which parts of the roof they’ll actually see
- Whether any drone flown is registered with the CAA
- Will the report include photos?
What happens on the day
The visit usually starts outside and finishes in the loft: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. All told, expect an hour or two at the house you’re buying, depending on its size and how much of the roof can be seen. Some parts of a survey depend on the weather, so a visit to Welham Green is booked with the forecast in mind: the parts that need calm, dry weather are planned around it.
- We help you pick the package that suits the property.
- A date is booked on a weekday, Saturday or Sunday.
- The coverings, ridges, valleys, flashings, chimneys and gutters are inspected and photographed.
- Moisture detection, structural checks, thermal imaging or a drone are added where your package includes them.
- We send the report with recommendations ranked by urgency, ready for you to discuss with the seller or agent.
Before the survey

- Unlock side gates and any roof access doors
- Let us know where we can park nearby

Why act early in Welham Green
A seller may honestly not know the state of the roof. The forms they complete only show what they’re aware of. Our survey shows you the roof as it is today, whatever anyone remembers. Around Welham Green, a leak in an older house can soak into timbers and plaster, which is far harder to put right than the roof fault itself.
Prices start from £150, including VAT. What you pay depends on how big and how high the roof is, access and the package you choose.
Why us?
- A sub-250g drone, flown with a CAA Flyer ID and Operator ID
- 5,000+ surveys completed
- Visits on any day of the week
- An independent view of the roof

What a pre-purchase roof survey looks like in Welham Green
Hatfield, which Welham Green is part of, is one of England’s post-war new towns. Homes from the post-war decades are common in the new towns, many with low-pitched roofs in concrete tiles and flat-roofed garages or porches. Whether you are buying or replacing a roof, low pitches and flat-roofed additions deserve a careful look. About 1.8 miles north lies Hatfield House, a reminder of how long the area around Welham Green has been built on. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and a listed home or one in a conservation area may need consent for changes of material.
The streets around a church like Church of St Mary the Virgin are often among the oldest in a place, and if your house is among the older ones nearby, older patch repairs can hide behind a tidy front slope, and the survey looks past them.

Practical tips
You do not need to be a roofer to help. Here’s what helps most:
- Check we’ll be able to get into the loft space
- Let us know your exchange date as you book
- Arrange the survey as soon as your offer is agreed
- Watch for stains or fresh paint on ceilings below the roof
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. What happens next is your decision and the seller’s, and we can’t promise any result.
Every so often, check the loft with a torch, keeping to boarded areas. Damp patches, daylight through the roof or water stains on timbers are worth noting. Photos help if you later need a roofer or another survey.
Questions from Welham Green
Are flat-roofed garages and porches in Welham Green worth including?
It is often worth it, as these roofs are easy to forget. Cement sheet roofs on buildings from before 2000 may contain asbestos, so a specialist asbestos surveyor should check before they’re disturbed.
Is Welham Green 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 need to go inside the property?
If it can be arranged, yes. From the roof space we can see staining, timbers and underlay. If we can’t get in, the report says so.
How long have you been surveying roofs?
Over 5,000 surveys so far, over more than 20 years, with 98% customer satisfaction.
Will the roof report help me negotiate with the seller?
Yes. The report sets out what we found, with photos, which you can share with the seller or agent. We can’t promise how the seller will respond.
Which days do you carry out surveys?
We survey on any day from Monday to Sunday, during the day, which suits people who work during the week. Let us know your preferred days when you book.
Does the weather affect the survey?
Light rain does not normally stop a survey, and it can even help show where water is getting in. Heavy rain or strong wind can ground a drone and make the roof unsafe, so if conditions are not right we’ll arrange another day with you.
