Flat roof surveys for homes and businesses in Thedden
A Basic Survey, from £150, covers a visual inspection, a condition report, photos and written recommendations. The Standard Survey, from £250, adds moisture detection and a structural check. On a flat roof, moisture readings can help show whether water has got under the covering. Bigger commercial roofs are priced on their size and access. Common reasons to book are failed seals around rooflight kerbs and standing water left after rain, on GRP fibreglass, EPDM rubber and single-ply membranes.
Older buildings in small places like Thedden may be listed or in a conservation area, which can shape what a new flat roof may look like. If you’re planning work, check with the council first. Knowing the roof’s condition is the starting point. Listed building consent is needed for changes that affect a listed building’s special interest.
The report is written in plain words, so it makes sense without any roofing background. Each point is backed by a photo where possible.

Flat roof surveys around Thedden
A number of Hampshire villages keep thatched roofs on their older buildings. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Next to the main roofs there’s typically a flat roof somewhere, whether on an extension, a garage or a commercial unit. Bentworth Hall, about 1 mile west, is one of the historic houses in the wider area around Thedden. 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.
Take an older house close to St Peter's: any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. If you own a rental within reach of Alton station, flat roofs on let property tend to be checked only when they fail, which is the costly way round.
Thedden is about 2 miles west of Alton, in Hampshire. Bookings from Thedden are handled just like any other: get in touch, agree the price and pick a day. We cover towns and villages across Hampshire, from the larger towns to small villages. Our Reading page covers surveys nearby.

Signs you need a flat roof survey in Thedden
Water that does not drain sits on the roof and speeds up wear. It normally comes from poor falls, a blocked outlet or a deck that has dipped. Where trees are close by, leaves and silt can block an outlet within a single autumn.
These are some of the problems a survey can pick up:
- Standing water left after rain
- Raised blisters across the surface
- A sagging deck under the covering
- Water getting in at rooflights
Take a building like Amery Hill School: ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.
Before booking any roof surveyor
- What’s outside the scope of the survey
- What exactly goes into their report
- How they plan to inspect the roof safely
- Whether the loft space is looked at, where there is one
Why act early in Thedden
If you’re buying, find out about the flat roof before you exchange. After that, the cost of any work is yours. A report gives you facts to put to the seller or agent. Outbuildings and barns around Thedden are easy to forget, but a failed roof there can spoil what’s stored inside. It is worth including them in a survey before a winter does the damage.

How we price flat roof surveys
All our prices include VAT. What changes the price is:
- House, block, shop or office
- Basic, Standard or Premium
- Whether thermal imaging or a drone is needed
- How big the roof is
A small, low roof with good viewpoints takes less time than a tall, complicated one, and the package matters as well. The price is always agreed first.
Helping us price your survey
When you call or email, these details help:
- Where water is showing inside, if it is
- Any photos you have, taken from the ground or a window
- Any deadline, like an exchange date
- How the loft is reached, if there is one
Photos help, if you have them. Pictures from the ground or a window are fine; never climb up to get a better view. To get started, ring 07833 053749 or email us.
The survey, step by step
After the inspection, everything we found is written up as a report with photos. On timing, it typically takes about 1–2 hours at most homes, while a commercial roof takes nearer three to four hours. Around Thedden, older homes can have small or awkward roof spaces, so it’s useful to know whether there’s a loft hatch and how easy it is to reach. Only areas that can be reached safely are inspected.
- You tell us about the roof, its covering if you know it, and any leaks.
- The roof is inspected from safe viewpoints, and from the roof itself where that is safe.
- We check and photograph the covering, the falls, the upstands, the outlets, the trims and any rooflights.
- Inside, we look for damp and staining under the roof where there is access.
- You get a report with photos and our recommendations.
How to prepare
- Buyers: confirm access with the estate agent or seller
- Mention any parking restrictions on your street
- Move anything stored under the loft hatch

Advice

How the survey changes by roof type
Rooflights and upstands
Rooflights, lanterns and upstands are where many flat roof leaks begin. We check the seals and the covering around each one.
EPDM rubber
EPDM is a synthetic rubber membrane, frequently laid in a single sheet on smaller roofs. The survey looks at laps, edge trims, corners and signs of puncture.
Checking the roof from ground level
You can learn a lot from the ground. With binoculars, look for slipped or missing slates and tiles, gaps along the ridge and leaning chimneys. Never climb onto the roof to look.
During heavy rain, look at the gutters from the ground or a window. Water spilling over the edge can point to a blockage or a sagging run.
Questions from Thedden
How do I find out if my home in Thedden is listed?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Do you cover smaller places like Thedden?
Yes. Thedden is within the area we cover, which takes in towns, villages and rural addresses. We survey roofs across London and the South East. Let us know about access, parking and anything unusual about getting there as you book.
When does the report arrive?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. Each one is emailed, ready to forward.
What does ponding on a flat roof mean?
Standing water on a flat roof deserves a closer look. It can point to blocked outlets, poor falls or a deck that is sagging, and it wears the covering faster. We record where it sits and the likely cause.
Does the weather affect the survey?
A survey can normally go ahead in light rain. Heavy rain or strong wind can ground a drone and make the roof unsafe, so we will agree a new date if the weather is not suitable.
I live in a flat. Can you survey the roof?
Yes. Shared roofs just need a little more planning, with whoever owns or manages the building. Mention it when you get in touch and we’ll explain what’s needed.
Are you insured?
Professional indemnity and public liability insurance cover our surveys. Ask if you need details for a managing agent or building owner.
