Flat roof surveys around Willian
Before planning roof work on an older home, find out whether it is listed or in a conservation area. Changes that affect a listed building’s special interest need listed building consent, and councils can also use Article 4 directions to control changes in conservation areas. Letchworth Garden City, which Willian is part of, was laid out as a garden city in the early twentieth century. Its first houses are now over a hundred years old, with later estates and newer homes around them. Older roofs may still have their original coverings, with fixings and underlay that have done a long stint, and parts of a garden city may be in a conservation area, so check with the council before re-roofing.
Take a building like Lordship Farm Primary School: schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks. If you live in an older home near Church of All Saints, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.
Willian is about 1 mile south of Letchworth, in Hertfordshire. We visit Willian as part of our work across Hertfordshire. Our Hertfordshire coverage includes Willian. For surveys nearby, see our Milton Keynes page.

Flat roof survey in Willian
A flat roof leak often travels before it shows on the ceiling. It may start at a split, a lifted seam or a failed upstand well away from the damp patch. That is why we check every detail across the roof, not only the area above the stain, with photos of anything that could be letting water in. A roofer can then start from a clear picture of the problem. If you are worried about a sagging deck under the covering and upstands pulling away from walls, we can find out what’s behind it.
Older buildings in small places like Willian may be listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. Check with the council before planning any change of material. Knowing the roof’s condition is the starting point. Changes that affect a listed building’s special interest need listed building consent.
Pictures do a lot of the work in our reports, so you can see each defect rather than just read about it. If something couldn’t be seen safely, the report is clear about it.

Surveys for landlords and agents in Willian
If the property is let, the agent or a tenant can let us in. Surveys run on weekdays and at weekends, which helps when tenants work during the week.
Freeholders and residents’ companies use a roof report to plan and budget, putting the urgent items at the top.
The survey, step by step
We will ask a few questions first, such as when any problem began and what work has been done before. Then the inspection itself takes about 1–2 hours at a typical home; commercial roofs usually need 3–4 hours. For a village or hamlet like Willian, the journey is planned in advance: let us know about lanes, gates and parking. On the day, we inspect what can be seen safely, inside and out.
- First you give us the address, what the roof covers and any leaks you’ve noticed.
- We check the roof from wherever it can safely be seen.
- Every part of the roof we can see is looked at: covering, falls, upstands, outlets, trims and rooflights.
- We check the rooms or spaces under the roof for staining where we can reach them.
- The findings are written up with photographs and recommendations and emailed to you.
Preparing for the visit
- Agree roof access with the managing agent if it is shared
- Let us know about parking near the property
- Gather any invoices or paperwork from past roof work
Arrange a survey
Prices start from £150, including VAT. What you pay depends on the roof’s size, access and the package, so ring 07833 053749 or email us with the details.
Advice
Common roof problems in Willian
People go onto flat roofs for all sorts of reasons: cleaning windows, fitting aerials or air conditioning, or clearing gutters. Each visit can damage a covering not made for regular foot traffic. Fixings added through the covering often start leaks too.
A survey can pick up problems such as:
- Signs of deflection in the roof deck
- Upstands pulling away from walls
- Leaks around rooflights
- Splits, cracks and crazing
If you own a rental within reach of Letchworth Garden City station, the flat roof over a let home is worth a look before it becomes a tenant complaint.
Before booking any roof surveyor
- Is VAT included in the price?
- Whether any drone flown is registered with the CAA
- How much experience they have with roofs like yours
- Whether the loft is part of the inspection

Before and after the survey
A few practical points come up again and again on our surveys. They’re worth knowing whatever the roof:
- Look for standing water a day after rain
- Ask contractors to protect the roof if they work on it
- Keep clear of rooflights and fragile roof sheets
- Check that new brackets or units haven’t damaged the covering
Many people send the report to two or three roofers for quotes. With each roofer working from the same list, comparing quotes is simpler. You stay in control of who does the work and when.
Have the roof surveyed every few years, and after any work that goes through it. That catches changes early and builds up a record of the roof.
Your questions about flat roof surveys in Willian
How do I find out if my home in Willian is listed?
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 Willian in the area you cover?
Yes, Willian is one of the places we work. The survey and report are the same in Willian as anywhere else, and visits run on weekdays and weekends.
How do you inspect a flat roof?
We inspect from wherever is safe: the roof itself where that’s safe, plus windows, vantage points and the rooms below. Fragile rooflights and fragile sheets are never walked on.
Do I have to be there for the survey?
Not always. If we only need the outside, we can agree that ahead of time, but anything inside needs someone there to give access.
I live in a flat. Can you survey the roof?
Yes, as long as access is agreed. Roofs over flats are often shared, so the building owner or managing agent needs to agree access. We inspect only the parts we’re allowed to reach.
How long have you been surveying roofs?
Over 20 years and more than 5,000 surveys, across London and South East England.
How much does a flat roof survey cost in Willian?
Prices start from £150, including VAT. We confirm the exact price before booking, and it depends on the roof’s size, access and the package you choose. To get a price, call 07833 053749 or use the contact form.
What a flat roof survey does not cover
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:
- The condition of the deck or insulation hidden under the covering
- An exact number of years the roof has left
- Areas we cannot see or reach safely, including fragile rooflights and sheeting
If you are not sure which survey you need, ring 07833 053749 or send us an email and we’ll give you a straight answer before you book. The full list of what we check.
Roof types and parts we check
- Upstands and outlets
- Felt flat roofs
- Single-ply membranes
- EPDM rubber

What a survey costs
Every roof is different, so prices are confirmed before you book. These are the things that affect it:
- Building height and the viewpoints available
- Commercial roofs and larger buildings
- Basic, Standard or Premium
- Extra roofs, like extensions, dormers or garages
We offer three survey packages: Basic from £150, Standard from £250 and Premium from £400, with VAT included. What your roof costs depends on its size, access and what you want to find out.
What to tell us when you get in touch
These details help when you contact us:
- Your timetable, such as an exchange date
- The type of building and roof, such as pitched or flat
- Photos of the roof, taken safely from ground level or a window
- Where the property is, with the postcode
