Leave it or get it looked at?
Photographs from ground level rarely show the detail. We get as close a view as safe access allows using a drone where it applies. Tradespeople may need to travel further to a smaller place like Welham Green, so it is useful to plan roof work rather than call someone out in a hurry. Knowing early gives you time to get the right people in.
New roof snagging starts from £150, including VAT. The final price depends on the size and height of the roof, how it can be seen safely and which survey you book.
What you get with us
- Thermal imaging and drones used where they help
- Over 5,000 surveys carried out
- Package prices that include VAT
- Two decades and more of roof surveys

How new roof snagging works in Welham Green
Our report records what we see, with photos and clear descriptions. If there’s a disagreement about the work, it’s between you and your roofer or builder. What we provide is an independent record of the roof’s condition. We don’t give repair cost estimates or decide who is at fault, but it describes what we saw in plain terms. Common reasons to book are ridge and hip tiles not properly fixed and underlay at the eaves left exposed, on loft conversions and dormers, flashings and valleys and new flat roofs.
Bungalows, chalet bungalows and older cottages are common in smaller places like Welham Green, many of them extended or given dormers over the years. Low roofs are easier to see from the ground, but dormer cheeks, valleys and flat-roofed additions still need close attention. That applies whether you’re buying in Welham Green or checking a new roof there. Snags and wear both tend to show at dormer lead work and along flat-roof edges.
The report works through the roof section by section, from the main slopes down to the gutters and outlets, with a note and a photo for each point. You’ll see the good as well as the bad.

What new roof snagging does not cover
Without opening up the roof, some things stay hidden, so a survey has limits:
- Pricing the remedial work
- Nails and clips under the slates or tiles
- Deciding who is at fault in a disagreement

Your questions about new roof snagging in Welham Green
Will you come out to Welham Green?
We do. A small place gets exactly the same survey as a big one, with the route planned beforehand.
Are flat-roofed garages and porches in Welham Green worth including?
Yes, if you’d like it included, mention it when you book. Cement sheet roofs on buildings from before 2000 may contain asbestos, so a specialist asbestos surveyor should check before they’re disturbed.
Does the weather affect the survey?
Light rain doesn’t normally stop a survey, and it can even help show where water is getting in. Strong wind or a downpour can stop drone flights and make roof access unsafe, so if conditions are not right we’ll arrange another day with you.
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 hold a CAA Flyer ID and Operator ID.
How soon after the work should I book a snagging inspection?
Once the roofer says the job is done, ideally before you pay in full. That gives time for any snags to be put right.
Is snagging available for a new-build house roof?
Yes. We check new-build roofs from safe vantage points and the roof space and record any snags. Book before the defects period runs out if you can.
Which days do you carry out surveys?
We survey seven days a week: Monday to Friday, Saturdays and Sundays. Let us know which days suit you when you book.
For landlords and managing agents
Letting agents can arrange access with tenants, at a time agreed in advance. We survey on weekdays and at weekends, which can make access easier.
Businesses and commercial landlords can book us too. Larger roofs take longer, and they’re priced for the size.
Different roofs, different checks
Underlay and ventilation
We look in the roof space, where there’s safe access, at the underlay and ventilation.
Slate roofs
On a new slate roof, we check the coursing and the details at ridges, verges and valleys as far as can safely be seen.
New roof snagging around Welham Green
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 any change of roofing material on a listed home needs checking with the council first. Hatfield, which Welham Green is part of, is one of England’s post-war new towns. Many homes in the new towns date from the post-war decades, with concrete interlocking tiles, low-pitched roofs and flat-roofed garages and porches. Low pitches, ageing concrete tiles and old flat roofs each have their own weak points, worth knowing before you commit.
Take an older house close to Church of St Mary the Virgin: a survey will show how the roof has been repaired before, which helps you judge what’s coming. If you let a flat or house near Welham Green station, a roof report gives you a clear picture before you buy or settle up with a roofer.

Practical tips
A little preparation and a few simple habits help. Our tips:
- Put any issues to your roofer in writing
- Agree snagging with your roofer at the start
- Look for new stains after a downpour
- Check lower roofs and walls after scaffolding comes down
Once the work is finished, check the ceilings and loft after the next downpour. Raise any new signs of water with your roofer promptly.
File the contract, invoices and warranty papers in one place. Add the snagging report to it.
