What a survey costs
A few things affect what a survey costs:
- The use of thermal imaging or a drone
- Whether it is a home or a commercial building
- How many separate roofs there are, like extensions, dormers and garages
- How tall the building is and how easy the roof is to see
Prices start from £150, including VAT. Basic starts from £150, Standard from £250 and Premium from £400, VAT included.
Helping us price your survey
Getting the details right at the start saves time. It helps to include:
- Your postcode, so we can check access and travel
- Where any leaks, stains or damp patches show inside
- How the loft is reached, if there is one
- Pictures from the garden or a window, if you have them
Surveys can be booked for weekdays, Saturdays or Sundays. To arrange a day that suits you, phone 07833 053749 or use the contact form.
Flat roof survey in Newnham: what you get
Many commercial buildings and blocks of flats have big flat roofs. A survey of a roof this size picks out worn covering, standing water and outlets that need attention. We record the condition with photos so work can be planned and budgeted. Commercial roofs are quoted for their size and access, so please phone 07833 053749 or drop us an email with the address and an idea of the roof’s size. We survey single-ply membranes, EPDM rubber and felt flat roofs, and people most frequently book us about gaps at upstands and abutments and leaks around rooflights.
Some older homes in villages like Newnham are listed or in a conservation area, which can shape what a new flat roof may look like. 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.
The report is written in plain words, so it makes sense without any roofing background. Photographs show what each point refers to.

Checking the roof from the ground
After heavy rain, check ceilings and the tops of walls for new stains. Photograph them and note the date, as it helps a surveyor trace the cause.
A lot can be seen from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please do not climb up for a closer look.
Local flat roofs in Newnham
In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, with flat-roofed extensions, dormers and garages common everywhere. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops. The wider area around Newnham has a long history of building, with Hinxworth Place about 1.4 miles north. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material.
The streets around a church such as Church of St Vincent are often among the oldest in a place, and if your house is among the older ones nearby, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. If you own a rental within reach of Baldock station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
Newnham is about 3 miles north-east of Letchworth, in Hertfordshire. Houses, flats, blocks and commercial buildings in Newnham can all book flat roof surveys, with a written report and photographs every time. We cover towns and villages across Hertfordshire. We also survey roofs in Milton Keynes.

Do you need a flat roof survey in Newnham?
Every flat roof covering has a working life. Around 15 to 20 years is common for felt, while EPDM often lasts 30 to 50 years and GRP up to about 30, although how well it was laid and looked after matters a great deal. A survey shows how yours is holding up, whatever its age.
We are often asked to look at:
- Outlets choked with leaves and silt
- Splits, cracks and crazing
- Loose or cracked edge trims
- A sagging deck under the covering
Take a building like The Knights Templar School: ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

FAQs for Newnham
Do you cover Newnham?
Yes, Newnham is within the area we cover. We survey roofs across London and the South East. You can call 07833 053749 or send us an email with the address and some details.
Is my home in Newnham listed or in a conservation area?
The council and Historic England’s list are the places to check. It is worth checking before planning roof work, as both can affect what’s allowed.
Can you survey a shared roof?
Yes, if whoever owns or manages the building agrees access. On a shared roof we can only inspect the parts we are allowed to reach, and the report makes that clear.
What does ponding on a flat roof mean?
Standing water a day or two after rain normally needs attention. It could be the outlets, the falls or a deflecting deck. We check each of these and record what we find.
Do you look for flat roof leaks?
We check the covering and every detail where leaks commonly start, and photograph anything that could be letting water in. If the source is hidden, we may suggest a leak investigation or electronic leak detection.
Is a flat roof survey the same as a building survey?
No. We look closely at the flat roof rather than the whole building. It complements a RICS home survey rather than replacing it, and structural calculations need a structural engineer.
How experienced are you?
More than 5,000 surveys over 20+ years, across London and South East England.
Why it’s worth a survey now in Newnham
Ponding seldom gets better on its own. Most often it means blocked outlets, poor falls or a deck that is dipping, and each wet season wears the covering further. Finding the cause now keeps more options open. Matching old materials, like handmade tiles or stone slates, can take time to source. Spotting a problem early leaves room to find them.
The cost of a survey depends on the roof: its size, its height, how many sections it has and how safely it can be seen. Flat roof survey starts from £150, including VAT.
Why us?
- 20+ years’ experience
- Thermal imaging and drones used where they help
- An independent view of the roof
- Drone flown under a CAA Flyer ID and Operator ID

When you need someone else
Our findings are based on what we can see safely on the day, so some things are outside what a survey can do:
- An exact number of years the roof has left
- Testing older roof sheets for asbestos
- Whether the deck or joists are strong enough
If you’re not sure which survey you need, phone 07833 053749 or drop us an email and we’ll give you a straight answer. What our survey covers.

The survey, step by step
After the inspection, everything we found is written up in a report with photographs, emailed to you. On timing, most surveys take about one to two hours for most houses, and more on a big or complicated roof. Around Newnham, older homes can have small or awkward roof spaces, so let us know about the loft hatch and any ladder. We only go where it is safe.
- We start with the details: the address, the roof’s use and any leaks or stains.
- The roof is inspected from safe viewpoints, and from the roof itself where that is safe.
- The covering, falls, upstands, outlets, edge trims and rooflights are checked and photographed.
- Inside, we look for damp and staining under the roof where there is access.
- The findings are written up with photographs and recommendations and emailed to you.
Getting ready for the survey
- Leave a clear route to the loft
- Let us know about parking near the property
- Buyers: confirm access with the estate agent or seller
