About our new roof snagging in Trowley Bottom
A new roof needs to breathe. We look for ridge, eaves or tile vents where they’ve been fitted, and check the loft space for signs of condensation. We note what we can see. Missing or blocked ventilation can lead to condensation over time, so it is worth raising early. We record what we see. If you’re worried about cracked or slipped new tiles or slates and underlay at the eaves left exposed, we can find out what’s behind it, on new-build homes, new flat roofs and ridges and verges alike.
Somewhere as small as Trowley Bottom, older cottages, farmhouses and converted buildings often sit beside a few newer homes. Older roofs there may have clay tiles, slate, stone or, in some places, thatch. Each covering has its own weak points, whether the roof is old or newly laid. Older roofs may also have old felt underlay or none, and fixings that have done a long stint.
Most points in the report come with a picture, because a photo of a cracked flashing says more than a paragraph. Anything out of sight on the day is listed as such.

Before and after the survey
You don’t need to be a roofer to help. What helps most:
- Check the roof before you pay in full
- Agree snagging with your roofer at the start
- Check ceilings and the loft after heavy rain
- Check before your warranty period ends
Once the work is finished, check the ceilings and loft after the next downpour. Raise any new signs of water with your roofer promptly.
Do not settle the final bill until the roof has been inspected if your contract allows it. It gives the roofer a reason to finish everything.
What new roof snagging looks like in Trowley Bottom
Historic houses such as Childwickbury Manor, about 4.5 miles south-east, show how far back building in the area around Trowley Bottom goes. Older roofs in the wider area can hide decades of patch repairs, so the detail matters. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles, and flat-roofed additions turn up almost everywhere. Each material has its own typical faults, which is what a buyer or the owner of a new roof needs to know about.
If you own a rental within reach of Harpenden station, a written report helps before buying a rental or paying for a new roof on one.

When to book a survey in Trowley Bottom
Owners frequently get in touch when the finish looks uneven or a leak appears. Others want an independent check as a matter of course before the job is closed.
Here are some of the things we see frequently:
- Flashings not properly dressed or fixed
- Cracked mortar at the ridge or hips
- Poorly finished verges
- Damage to other parts of the building
Take an older house close to Church of St Leonard: a survey will show how the roof has been repaired before, which helps you judge what’s coming.

What affects the cost of new roof snagging
Every roof is different, so prices are confirmed before you book. This is what makes a difference:
- The roof’s overall size
- Features like valleys, chimneys, dormers and parapets
- The height of the building and how the roof can safely be seen
- How many separate roofs there are, such as extensions, dormers and garages
Price depends partly on the package: Basic from £150, Standard from £250 or Premium from £400, all including VAT. Size, height and access can affect the price too.

Common questions in Trowley Bottom
Is my home in Trowley Bottom listed or in a conservation area?
Start with Historic England’s list for listing and your council for conservation areas. It is worth checking before planning roof work, as both can affect what’s allowed.
Is Trowley Bottom in the area you cover?
We do. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
Does the weather affect the survey?
A survey can usually go ahead in light rain, 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 aren’t right we’ll arrange another day with you.
What does a new roof inspection include?
We check the coverings, ridges, verges, hips, valleys and flashings, along with ventilation, gutters and the underlay at the eaves. We look for leftover debris and knock-on damage too.
Is this an asbestos survey?
No. We can flag materials that might contain asbestos, but confirming it is a job for a specialist asbestos surveyor. Buildings built or refurbished before 2000 may contain it.
Can you see the fixings under the tiles?
No, we don’t disturb the new coverings. Fixings and underlay under the slates or tiles are hidden, but we look at everything we can see safely.
Can you inspect my roof with a drone?
Yes, where it’s applicable. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and the airspace and weather are checked before every flight.

The survey, step by step
Photos are taken throughout the visit, so the report shows exactly what we saw. Close-ups come from the safest viewpoint available. A typical visit takes an hour or two for most houses, and longer for a large or complex roof. Somewhere as small as Trowley Bottom, access is frequently the only tricky part. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Weekday and weekend visits are available.
- First, you tell us what the roofer did and any concerns you have.
- The coverings, ridges, hips and verges are checked as far as can be seen safely.
- We check valleys, flashings and gutters, and the underlay at the eaves where it is visible.
- The roof space is checked where safe, along with any mess or damage left after the work.
- The snags are written up with photos for you to share with your roofer.
Before the survey
- Point out any leaks or damp patches
- If the roof is shared, arrange access with whoever manages the building
- Leave a clear route to the loft

What we look for on each type of roof
Valleys
Valleys carry a lot of water, so the detailing matters. We look at the valley lining and the cut tiles or slates beside it.
Ridges, hips and verges
The top and edges of a roof are the most exposed. Bedding, dry-fix pieces and fixings are checked where visible.
