New roof snagging in Welwyn Garden City: what you get
Ventilation matters on a new roof. We look for ridge, eaves or tile vents where they’ve been fitted and look in the loft space for condensation. What we see goes in the report. Missing or blocked ventilation can lead to condensation over time, which is easier to put right while the roofer is still involved. We record what we see. If you’ve noticed untidy or loose verge details and underlay at the eaves left exposed, a survey will tell you what’s going on, on replacement roofs, loft conversions and dormers and new-build homes alike.
Around towns like Welwyn Garden City, many houses have gained extensions, dormers, porches or garages, often with flat roofs. The joints where a new roof meets an old wall or slope are a common source of leaks. On a purchase or a newly finished roof in Welwyn Garden City, those junctions are high on the list.
The Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

Why it’s worth a survey now in Welwyn Garden City
Raising snags before the final payment is normally simpler. After the final payment, getting them back can take longer. Our report lists what to raise. Around Welwyn Garden City, gutters that overflow soak the wall below. A slipped tile or worn flashing does the same higher up. Neither gets better on its own.
Price depends partly on the package: Basic from £150, Standard from £250 or Premium from £400, all including VAT. The roof’s size, height and access matter as well.

Common questions in Welwyn Garden City
Is there anything to prepare before you come to Welwyn Garden City?
It helps to clear access to the loft, and to let us know about leaks, damp patches or recent work. Let us know about parking and access in Welwyn Garden City too.
Is Welwyn Garden City in the area you cover?
We do. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.
Will you fly a drone over my roof?
Where it helps and the rules allow, yes. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and the airspace and weather are checked before every flight.
Which parts of the roof does snagging cover?
We check the coverings, ridges, verges, hips, valleys and flashings plus gutters, ventilation and visible underlay at the eaves. We look for leftover debris and knock-on damage too.
I live in a flat. Can you survey the roof?
Yes, once whoever controls the roof agrees access. We check the parts we are given access to.
Will you go up on the roof?
Not unless it’s safe. Most of what we need can be seen from safe viewpoints, the loft and, where it applies, a drone, and anything out of sight is recorded in the report.
How much is new roof snagging?
The Basic Survey starts from £150, the Standard from £250 and the Premium from £400, all including VAT. Just call 07833 053749 or drop us an email for a price.
When to book a survey in Welwyn Garden City
Roofers do not always clear every gutter and lower roof. Offcuts and broken pieces often end up in the gutters and on extension roofs.
Problems we come across frequently include:
- Missing or blocked roof ventilation
- Loose or badly finished ridge tiles
- Broken coverings left on a new roof
- Flashings not properly dressed or fixed
If you own one of the older houses in the streets near Church Of Saint Francis Of Assisi, the roof’s history matters as much as its looks, and a survey brings the past repairs to light.
Before booking any roof surveyor
- How long they’ve been surveying roofs
- What the survey won’t cover
- How soon the report will arrive
- Their drone registration, if they fly one
How we price new roof snagging
What a survey costs depends on the time and equipment it needs. The main factors are:
- Building height and the viewpoints available
- How complicated the roof is, with its valleys, chimneys and parapets
- How big the roof is
- House, block, shop or office
We offer three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, with VAT included. What your roof costs depends on its size, access and what you want to find out.
What we need to know
To price your survey accurately, we’ll ask about:
- The style of property, from a terrace to a block
- Whether there is a loft hatch, a shared roof or tricky access
- Pictures from the garden or a window, if you have them
- Why you want a survey: buying, a leak, a storm or new work
Booking is simple: just ring 07833 053749 or send us an email, tell us about the property and we will explain which survey suits. We confirm the price before anything is booked.
The survey, step by step
We work from the outside in: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. All told, expect between one and two hours for most homes, depending on how much new work there is to check. For a visit in Welwyn Garden City, we need access to the loft, any rooms with leaks or stains, and the outside of the building. Mention gates, side passages and anything at the back. Visits can be on weekdays, Saturdays or Sundays.
- We ask what work was done and when it was finished.
- The new coverings, ridge, hips and verges are inspected where it is safe to see them.
- Valleys, flashings, gutters and the underlay at the eaves are looked at.
- We look in the roof space, where there’s safe access, and around the property for debris or damage.
- You get a photo report listing the snags we found.
How to prepare
- Check we can get to the back of the property
- Buyers: confirm access with the estate agent or seller
- Keep pets inside or away from the areas we’re looking at

Buying a home or a new roof in Welwyn Garden City
Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles. Each material has its own typical faults, which is what a buyer or the owner of a new roof needs to know about. The wider area around Welwyn Garden City has a long history of building, with Digswell House about 1.5 miles north. If yours is one of the older homes, expect a mix of original materials and later repairs on the roof, and any change of roofing material on a listed home needs checking with the council first.
If you let a flat or house near Welwyn Garden City station, the roof is worth checking before you add another property to a portfolio or pay a roofer in full.

Before and after the survey
These tips come from what we see on roofs every week:
- Walk round the house to look for knock-on damage
- Diary the defects period end date
- Book snagging before the final payment
- Look for new stains after a downpour
Once the work is finished, check the ceilings and loft after the next downpour. If anything shows, tell your roofer straight away.
Keep an eye on the roof and ceilings in the first months. It is simpler to raise problems soon after the job.
