Flat roof survey in Wherwell: what you get
Standing water is one of the first things we look for on a flat roof. It can mean the falls were never right, an outlet is blocked or the deck has started to sag. The survey notes any ponding, the state of each outlet and any dips that hint at a sagging deck. Where the deck may be a structural issue, our report says a structural engineer should look at it. We survey single-ply membranes, EPDM rubber and felt flat roofs, and common reasons people get in touch are signs of deflection in the roof deck and blocked or damaged outlets.
Some older homes in villages like Wherwell are 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. Listed building consent is needed for changes that affect a listed building’s special interest.
If any part of the flat roof couldn’t be seen safely, we say so in the report. You’ll know exactly what was inspected and what wasn’t, and what we’d suggest next.

When you need someone else
Our findings are based on what we can see safely on the day, so there are some things a survey cannot cover:
- A fixed date for when the roof will need replacing
- What’s under the membrane without opening it up
- Parts of the roof that aren’t safe to walk on or view
If you are not sure which survey you need, ring 07833 053749 or use the contact form and we will give you a straight answer before booking. What a survey covers and doesn’t.
What this survey covers
- Single-ply membranes
- Upstands and outlets
- Felt flat roofs
- EPDM rubber
- GRP fibreglass
- Mastic asphalt
Before and after the survey
These tips come from what we see on roofs every week, before and after a survey:
- Have the roof looked at again after a severe storm
- Keep records of when the roof was laid and what work has been done
- Note where water lies after a downpour
- Ask whoever fits equipment on the roof to make good the covering
Landlords, owners and managing agents can keep the report as a dated record of the roof. It’s useful when planning upkeep and setting budgets, and it gives a baseline to compare against next time.
After heavy rain, look at the roof from an upstairs window if you can. If water is still there a day or two later, have it checked.

Leave it or get it looked at?
Before replacing a flat roof, it is useful to know if you really need to. At times the trouble is a handful of failed details, and at times the whole covering is worn. Our report gives you the evidence to discuss with a roofer. Around Wherwell, older homes often have old roof timbers, and water through a failed covering can rot timber if it’s left.
Prices quoted always include VAT, and the report isn’t charged as an extra. Flat roof survey starts from £150, including VAT. Size, height and access decide where your roof falls.

Your questions about flat roof surveys in Wherwell
Is my home in Wherwell listed or in a conservation area?
The council and Historic England’s list are the places to check. Either can affect what roof work is allowed, so it’s worth checking before planning any.
Do you cover Wherwell?
Yes, Wherwell is one of the places we work. The survey and report are the same in Wherwell as anywhere else, and visits run on weekdays and weekends.
Are you structural engineers?
No. Our survey isn’t a structural engineer’s report. If we see signs that need an engineer’s opinion, we’ll recommend one.
Which days do you carry out surveys?
Surveys can be booked for any day of the week: Monday to Friday, Saturdays and Sundays. Just tell us the days that suit you.
Can you tell me how long my flat roof will last?
There’s no honest way to give an exact number of years. Typical ranges are around 15 to 20 years for felt, 30 to 50 for EPDM and up to about 30 for GRP, but the report tells you how your roof is really doing.
Are you insured?
Our cover is professional indemnity plus public liability, and we can provide details if a managing agent needs them.
Can you test old roof sheets for asbestos?
Our survey doesn’t include asbestos testing. Older buildings, from before 2000, may have asbestos in cement sheets or soffits. Anything that might contain it is flagged, so a specialist asbestos surveyor can check before work starts.
Rented homes, blocks and businesses
We survey roofs for landlords and agents as well as homeowners. The report gives you a dated record of the flat roof, with photos, useful for planning maintenance.
If you own several properties, surveys can be booked for more than one address. To discuss a number of properties, phone 07833 053749 or drop us an email with the addresses.
How it works
It helps to start with what’s prompted the survey: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. The visit usually takes between one and two hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. Cottages and farmhouses around Wherwell frequently have roofs at several levels, with lean-tos and outbuildings attached. We work round each section in turn, from the safest viewpoints.
- You send us the address and, for commercial roofs, an idea of the roof’s size.
- We check the rooms or spaces under the roof for staining where there is access.
- The roof is inspected from every safe viewpoint, without walking on fragile surfaces.
- We record every defect with a photo and its likely cause.
- You get a report setting out the condition and our recommendations, in order of urgency.
Preparing for the visit
- Leave a clear route to the loft
- Make a note of anything you’d like us to look at
- Unlock side gates and any roof access doors

Flat roofs in Wherwell
England has around 10,000 conservation areas and about 500,000 listed buildings. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material, so the council is the place to ask. 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. Alongside them, flat-roofed extensions, dormers, garages and commercial units are common almost everywhere.
For landlords with property near Andover station, the flat roof over a let home is worth a look before it becomes a tenant complaint. Take an older house close to Church of St Peter and Holy Cross: later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear. Anyone responsible for a site like Wherwell Primary School will know that a large flat roof with lots of outlets and rooflights has many places where a membrane can fail.

Roof by roof
Single-ply membranes
Plant, fixings and foot traffic can all damage a single-ply roof. We note any punctures, tears and loose areas we can see.
Felt and built-up roofs
Built-up felt is one of the most common flat roof coverings on extensions, garages and dormers. We look for blistering, cracking, split laps and worn mineral surfacing.
