Roof surveys for homes and businesses in Welwyn
Our report is written in plain English, not jargon. Each defect is described with photographs and a recommendation, and we rank them by urgency where that helps. With the Standard Survey you also get moisture detection and a structural check. Premium adds thermal imaging, a drone inspection where applicable and a same-day report. Reports are sent by email. We survey flat roofs, natural slate and chimney stacks, and the problems we’re asked to look at most are standing water on a flat roof and slates or tiles that have slipped or broken.
In a smaller place like Welwyn, some roofs stand more exposed to wind and rain than in a built-up town. That weather tells first on ridges, verges, chimneys and flashings. Checking those edges shows whether anything has begun to work loose. Once one ridge tile or slate moves, wind gets under the next one too.
Every survey ends with a written report, with photographs, emailed to you. It explains the condition of the roof, the defects we found and what we recommend.

FAQs for Welwyn
How do I find out if my home in Welwyn is listed?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it is worth checking before planning any.
Can a landlord with a rental near Welwyn North station book a roof survey?
Yes. We survey roofs for landlords, letting agents and managing agents as well as owners. Just call 07833 053749 or email us with the details, and we’ll talk through which survey suits.
Can you survey at the weekend?
We survey seven days a week: Monday to Friday, Saturdays and Sundays. Let us know which days suit you as you book.
How long does a roof survey take?
It normally takes about one to two hours on an ordinary house, with bigger or more complicated roofs taking longer. The report follows within 48 hours for Basic, 24 to 48 hours for Standard and the same day for Premium.
Do I need to be at home?
If the survey includes the loft or the inside of the building, someone needs to let us in. We will talk about access when booking.
How much is a survey?
Our price is from £150, including VAT. We confirm the price for your roof before you book, and it depends on the roof’s size, access and the package you choose. For a price, phone 07833 053749 or email us.
What does a roof survey include?
We check the coverings, ridges, hips, valleys, flashings, chimneys and gutters, along with the loft where it is safe. You get a photo-illustrated written report and recommendations.
Do you need a roof survey in Welwyn?
A chimney stack takes more weather than almost any other part of a roof. Mortar crumbles, the flaunching around the pots cracks and stacks can lean. Damp on a chimney breast inside often starts at the top of the stack.
People normally book a survey after spotting one of these:
- Leaking gutter joints and downpipes
- Cracked mortar along the ridge
- Flashings that have come away from the wall
- Leaning or weathered chimney stacks
If you run a business near Howard Centre, knowing the roof’s condition lets you budget for work rather than pay for emergencies.

How it works
We photograph the roof as we go, so the report shows exactly what we saw. Close-ups come from the safest viewpoint available, including by drone where it is applicable and the weather allows. A typical visit takes between one and two hours at a typical home, though large, tall or awkward roofs take more time. 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 pick the package that suits your roof.
- On the day, we start by hearing what you’ve noticed.
- We inspect and photograph every part of the roof we can safely see.
- Extra checks are carried out where your package includes them.
- The report is emailed with findings and recommendations.
How to prepare
- Have keys ready for side gates, garages or roof access doors
- For flats, check roof access has been agreed
- Move anything stored under the loft hatch
How to book
Photos help, if you have them. Take them safely from ground level or a window. To send them or to book, call 07833 053749 or use the contact form.
Advice
What you can safely check yourself
Watch the gutters in a downpour, from a window or the ground. Overflowing water can point to a blockage or a sagging run.
Look up at the roof after a storm, from ground level: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Don’t go up yourself.
Roofs, chimneys and gutters in Welwyn
The wider area around Welwyn has a long history of building, with Digswell House about 0.9 miles south-east. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles. Each of these coverings has its own weak points, from fixings and valleys to flashings, chimneys and gutters.
For landlords with property near Welwyn North station, a roof report between tenancies helps plan work before a small defect becomes a tenant’s leak. Living close to Danesbury Park is pleasant, but mature trees mean leaves in gutters and valleys each autumn, and blocked gutters overflow and soak walls.

What happens if roof problems are left?
By the time water marks a ceiling, it’s often been getting in for a while. Damp spreads through insulation and timber before anything shows below. A survey can pick up the early signs from the loft. Around Welwyn, leaves and moss in gutters lead to overflowing water and damp walls, especially where trees overhang. It is easy to sort the cause early and slow to dry a damp wall.
Bigger, taller and commercial roofs take more time to survey, so the price reflects that. The price is confirmed before booking.
