Liss Forest questions
Do you cover smaller places like Liss Forest?
Yes. Liss Forest is within the area we cover, which takes in towns, villages and rural addresses. We cover the whole of London and South East England. Let us know about access, parking and anything unusual about getting there when you book.
How do I find out if my home in Liss Forest is listed?
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.
Does the weather affect the survey?
A survey can normally go ahead in light rain, and it can even help show where water is getting in. High wind or heavy rain can stop drone flights and make roof access unsafe, so if conditions aren’t right we’ll arrange another day with you.
Can you give me structural calculations?
No. We note visible signs such as sagging or deflection, but we’re not structural engineers and do not carry out calculations. Where an engineer is needed, we say so in the report.
How long have you been surveying roofs?
Over 20 years and more than 5,000 surveys, across London and South East England.
When does the report arrive?
Each package has its own report time. Basic is within 48 hours, Standard is 24–48 hours and Premium is the same day. Mention any deadline when you book.
How long does the survey take?
Expect it to take about one to two hours on an ordinary house; commercial roofs usually need 3–4 hours. You’ll then get the report by email, on the timescale of your package.
How a flat roof survey works in Liss Forest
Offices, shops, industrial units and blocks of flats frequently sit under large 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 ring 07833 053749 or send us an email with the address and an idea of the roof’s size. If you’re worried about failed upstands where the roof meets a wall and water getting in at rooflights, a survey will tell you what’s going on, on EPDM rubber, upstands and outlets and mastic asphalt alike.
Flat roofs on exposed homes in small places like Liss Forest take more wind and rain, which is hard on edges, upstands and joins in the covering. Felt roofs, which often last around 15–20 years, typically show it first. Rubber and GRP last longer, though trims and joints still need a look. On an exposed roof, the edges tend to go first.
It isn’t only a list of defects. For each finding, it explains what it is, why it matters and what we’d recommend, so you can plan your next steps.

DIY checks: what’s safe
What you cannot do safely is get up close. Slates, tiles, flat roofs and rooflights can give way. That part is for a survey.
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Share it with us as you book, as it helps us focus the survey.
What a survey costs
Not every roof costs the same to survey, and it comes down to:
- Basic, Standard or Premium
- Roof area
- How many separate roofs there are, such as extensions, dormers and garages
- Height and safe access
Prices start from £150, including VAT, for a Basic Survey. Standard is from £250 and Premium from £400, both inc. VAT. We confirm the price for your roof before booking.
Getting in touch
Here’s what helps us most when you contact us:
- Pictures of the roof from a safe spot, if you have them
- The reason for the survey, such as buying, a leak or storm damage
- Any stains, drips or damp patches you’ve seen indoors
- Your timetable, like an exchange date
Flat roof survey starts from £150, including VAT. What you pay depends on the roof’s size, access and the package, and you can ring 07833 053749 or drop us an email to find out.
Common roof problems in Liss Forest
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.
It is worth booking a survey if you’ve seen:
- Ponding water that does not drain away
- Water getting in at rooflights
- Blisters and bubbles in the covering
- Outlets choked with leaves and silt
For landlords with property near Liss station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

What we look for on each type of roof
Rooflights and upstands
The joins around rooflights and at upstands are common leak points. We look at how the covering is finished around each rooflight and upstand.
Single-ply membranes
Single-ply relies on its welded laps staying sound. We check seams, corners and the joints around outlets and upstands.
Honest limits
It is a careful look at the flat roof, not the whole story. The main limits are:
- Asbestos testing, which needs a specialist asbestos surveyor
- Fragile surfaces, which we do not walk on
- A promise that the roof will not leak in future
If you are not sure which survey you need, ring 07833 053749 or use the contact form and we’ll give you a straight answer before you book. The full list of what we check.

Flat and commercial roofs around Liss Forest
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. Some Hampshire villages still have thatched roofs. In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops.
For site and facilities teams at buildings like Liss Infant School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. Take an older house close to St Saviour's: the joins between later flat roofs and the old walls are where problems typically start.

What we do, step by step
We check the roof from outside and, where it’s relevant and there’s safe access, from inside the loft space too. In the loft, the signs we look for are staining, damp, daylight and sagging, as far as the space allows. The whole visit normally takes an hour or two for a small flat roof at home, and longer for a large commercial one. Older rural homes like those around Liss Forest can have a main roof, lower lean-to roofs and outbuildings all joined together. Each part is looked at from wherever it can safely be seen.
- We start with the address and, on larger roofs, the roof area and access.
- Inside, we look for signs of water under the roof where we can reach.
- We view the roof from safe positions and never walk on fragile surfaces.
- Each defect is photographed and its likely cause noted.
- You get a report setting out the condition and our recommendations, in order of urgency.
Before the survey
- For a flat or shared roof, check access with the building owner or managing agent
- Point out any leaks or damp patches
- If you’re buying, let the agent know when we are coming
