New roof snagging in Welwyn, Hertfordshire
New roof snagging in Welwyn, with over 20 years’ experience behind it. You get a clear report with photographs.

Why it’s worth a survey now in Welwyn
Leaving debris in gutters can cause overflows that soak walls. Finding it now is simpler than tracing damp later. In an older home around Welwyn, water from a roof defect can get into timber and plaster, and that’s a much bigger job than the original defect.
Prices quoted always include VAT, and the written report is part of the package. New roof snagging starts from £150, including VAT. Size, height and access decide where your roof falls.
Why book with us
- Insured for professional indemnity and public liability
- A sub-250g drone, flown with a CAA Flyer ID and Operator ID

- Thermal imaging and drone inspection where they help
Take a look at how roof surveys are priced and two real surveys.
New roof snagging in Welwyn
We check the coverings, ridges, verges, hips and valleys, along with the flashings and ventilation. We check the underlay at the eaves where it is visible as well as the gutters. You get a photo report of what we found. Any debris left behind or damage to other parts is recorded too. We’re often asked to look into ridge and hip tiles not properly fixed and signs of condensation in the roof space, on ridges and verges, flashings and valleys and new-build homes.
Houses in smaller places like Welwyn can stand more in the open than those in a built-up town, which can mean more wind and rain on the roof. Ridges, verges and flashings are where that weather normally shows first. Whether you’re buying or signing off new work, those edges deserve a proper look. Wind lifts anything already loose, so a small fault on an exposed roof doesn’t stay small for long.
The report records the new roof as we found it on the day. It’s useful straight away, and a good reference for later, for instance when you want to check whether anything has changed.

How the survey changes by roof type
Flashings
Chimney flashings are a frequent source of leaks, so we check them closely.
Ridges, hips and verges
Cracked mortar or loose ridge tiles on a new roof are worth raising. They’re recorded with photos.
Before and after the survey
Here are a few things we’d tell any owner, before and after a survey:
- Look for debris left in gutters from the ground
- Raise snags in writing with your roofer
- Book snagging before the final payment
- Keep the contract and invoices together
After the snags are sorted, watch the roof in the next heavy rain. If anything shows, tell your roofer right away.
Keep an eye on the roof and ceilings in the first months. It’s simpler to raise problems soon after the job.
When you need someone else
Some things cannot be seen without opening up the roof, and that sets some limits:
- Pricing the remedial work
- Details hidden from sight
- Legal advice on your contract

How the survey works
We work from the outside in: outside views come first, then the loft space if there’s safe access. In total, it takes between one and two hours for a typical new house roof, longer where the roof is large or complicated. A visit to Welwyn is planned like any other: the time, the access and where to park are agreed beforehand. Visits can be on weekdays, Saturdays or Sundays. If there are outbuildings or garages you want looked at, mention them.
- You let us know what work was done and when.
- We check the coverings, ridges, hips and verges from safe vantage points.

Advice
Local roofs and buyers in Welwyn
With Digswell House about 0.9 miles south-east, Welwyn sits in an area with a long building history. On older houses around here, roofs often 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. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Material and age explain a lot of what turns up on the day, whether the roof is old or brand new.
Landlords with a home close to Welwyn North station may find that a survey before purchase, or before signing off a new roof, saves surprises once a tenant moves in. The streets around a church like Parish Church of St Mary are often among the oldest in a place, and if yours is one of the older homes nearby, older patch repairs can hide behind a tidy front slope, and the survey looks past them.

FAQs for Welwyn
How do I find out if my home in Welwyn is listed?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case.
Do you cover Welwyn?
We do. Every survey there gets the same written report with photos.
Does the weather affect the survey?
It depends on the weather and the survey. Strong wind or heavy rain can make access unsafe and ground a drone, and we’d agree another day.
Is this a RICS survey?
No. Our survey looks at the roof, not the whole building. For the rest of the building, a RICS home survey is a separate job.
Do you carry out surveys on Saturdays and Sundays?
We carry out surveys on any day of the week. To find a day that suits you, ring 07833 053749 or drop us an email.
How do I book a survey in Welwyn?
To arrange a survey, call 07833 053749 or use the contact form with the address, the type of property and what’s prompted the survey. We will confirm the price and find a day that suits.
Will you walk on the roof?
Not unless it’s safe. Most of what we need can be seen from safe viewpoints, the loft and, where applicable, a drone, and the report notes anything we couldn’t see.
