Questions from Tewin
Do you cover smaller places like Tewin?
Yes, smaller places are covered as well as towns. We survey roofs across London and the South East. Let us know about access, parking and anything unusual about getting there when booking.
Does a conservation area affect roof work in Tewin?
The council and Historic England’s list are the places to check. It’s worth checking before planning roof work, as both can affect what’s allowed.
Do you survey roofs on blocks of flats?
Yes. A shared roof needs access agreed first. Tell us about it as you book and we’ll explain what’s needed.
Will you fly a drone over my roof?
Where it’s applicable and safe, yes. We are a CAA-registered drone operator (Flyer ID and Operator ID), flying a sub-250g drone. It is included in the Drone Roof Survey and, where it applies, the Premium Survey.
Is this the same as a RICS Level 2 or Level 3 survey?
No. Our survey looks at the roof only, and it is not a RICS home survey. It complements one rather than replacing it.
Does someone need to be in?
Not necessarily. If we only need the outside, we can agree that ahead of time, but the loft and any rooms with damp need someone to let us in.
Do you carry professional indemnity insurance?
Professional indemnity and public liability insurance cover our surveys. Ask if you need details for a managing agent or building owner.
About our pre-purchase roof survey in Tewin
With a written roof report, you can go back to the seller or agent with specifics. You might ask about past repairs, ask for work to be done before completion or think again about your offer. We cannot say how a seller will respond, but you will be asking from facts rather than guesses. It also helps you decide whether to go ahead at all. We’re frequently asked to look into damp timbers or stains in the loft and lead that has worked loose at a wall or chimney, on chimney stacks, lead flashings and valleys and natural slate.
In a village or hamlet like Tewin, homes are often older cottages and farmhouses alongside a few newer houses. Older roofs there may have clay tiles, slate, stone or, in some places, thatch. Whether you’re buying or have just had a roof replaced, each material has its own checks, and thatch is a specialist material, so we report on what can be seen. What’s under the coverings, from old felt to the battens and nails, matters too.
Where we can’t see part of the roof, the report says so. You will know exactly what was inspected and what wasn’t.

Local roofs and buyers in Tewin
Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates, with flat-roofed extensions, dormers and garages common everywhere. The covering on a house you are buying, or on a roof just finished, tells us where to look hardest. If your survey includes the drone, we check the Drone Safety Map for restrictions before flying.
Digswell House, about 2.1 miles west, is one of the historic houses in the wider area around Tewin. Older homes in the area can come with listed status or conservation area rules, which affect re-roofing, so check with the council before you buy. If you own one of the older houses in the streets near Church of St Peter, a survey will show how the roof has been repaired before, which helps you judge what’s coming.

Do you need a pre-purchase roof survey in Tewin?
Viewings rarely include a proper look at the roof. You see the rooms, not the slates. New paint on a ceiling can hide old water stains, which is why buyers book a closer look before committing.
Things that frequently lead to a survey include:
- Quick fixes on flashings and valleys
- Gutters that overflow or drip at the joints
- Blistered or split felt on a flat roof
- Damp timbers or stains in the loft
If you own a rental within reach of Welwyn North station, it’s worth knowing a roof’s condition before you buy it, or before you sign off new roofing work on it.
Questions to ask before booking
- Will they check the loft as well as the outside?
- What happens after the report arrives
- Which limits apply to the survey
- What exactly goes into their report
When you need someone else
Our survey is not a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- Confirmation of asbestos in cement sheets or soffits
- A structural engineer’s report
- Faults hidden behind ceilings, boards or coverings

- Chimney stacks
- Lead flashings and valleys
- Flat-roofed extensions and dormers
- Gutters and downpipes
- Natural slate
Different roofs, different checks
Chimney stacks
A stack stands exposed above the roof line. The pots, flaunching, pointing and flashings are all checked, as far as we can see them safely.
Gutters and parapets
Some older terraces have a butterfly roof with a central valley gutter. If the home you are buying has one, that gutter and its outlet get a careful look.
What we do, step by step
Photos are taken throughout the visit, so the report shows exactly what we saw. We take close-ups from wherever is safe, including by drone where it’s applicable and the weather allows. A typical visit takes between one and two hours at a typical house, with time for the loft where it can be reached. Somewhere as small as Tewin, access is often the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- We help you pick the package that suits the property.
- We agree a visit, including weekends if that helps.
- The coverings, ridges, valleys, flashings, chimneys and gutters are inspected and photographed.
- Standard and Premium surveys add the extra checks they include.
- You receive the report, with findings prioritised by urgency, so you can raise them with the seller.
Before we arrive
- For flats, check roof access has been agreed
- Move anything stored under the loft hatch
- Dig out any old roof reports or invoices
Arrange a survey
We survey roofs seven days a week. To find a date that works for you, phone 07833 053749 or email us.
