Flat roof survey in Stonehill, Surrey

What we are asked to look at in Stonehill
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, though workmanship and upkeep make a big difference. We can tell you how your roof is doing, whatever its age.
People typically book a survey after spotting one of these:
- Failed upstands where the roof meets a wall
- Signs of deflection in the roof deck
- Water getting in at rooflights
- Cracked or split membrane
Shop and office owners around The Peacocks may find that outlets and upstands on commercial flat roofs are the places to check before trouble starts.
Questions to ask before you book
- Their insurance cover
- Whether the roof space is looked at, where there is one
- How they’ll see the roof: from the ground, the loft, the roof or by drone
- What’s outside the scope of the survey
Flat roof surveys for homes and businesses in Stonehill
Buying a home with a flat-roofed extension, dormer or garage? It helps to know that roof’s condition before you exchange. Felt roofs often last around 15 to 20 years, while EPDM and GRP often last longer. We set out the type of covering, its condition and the defects we found, with photos of each. You then have something specific to put to the seller or agent. We survey mastic asphalt, EPDM rubber and felt flat roofs, and people most often book us about splits, cracks and crazing and damaged trims at the roof edge.
In a small place like Stonehill, a flat roof can stand in the open, which is hard on edges, upstands and joins in the covering. Older felt roofs, frequently around 15–20 years in life, show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. On an exposed roof, the edges tend to go first.
Report times depend on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

What a flat roof survey looks like in Stonehill
Many older homes in Surrey have handmade clay tiles and tile-hung upper walls. A few of Surrey’s oldest buildings have heavy Horsham stone slab roofs. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops. Historic houses such as Botleys Mansion, about 1.4 miles north-east, show how far back building in the area around Stonehill goes. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and a listed home or one in a conservation area may need consent for changes of material.
Landlords with a home close to Longcross station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak. If you look after a building such as Salesian School, a large flat roof with lots of outlets and rooflights has many places where a membrane can fail.

How we price flat roof surveys
A few things affect what a survey costs:
- Whether it is a home or a commercial building
- The height of the building and how the roof can be seen safely
- The roof’s overall size
- How complicated the roof is, with its valleys, chimneys and parapets
A Basic Survey starts from £150, with VAT included. Standard is from £250 and Premium from £400. We confirm the exact price before booking.
What we need to know
A little information up front helps. It is useful to include:
- The style of property, from a terrace to a block
- Photos of the roof, taken safely from the ground or a window
- Dates you are working to, like exchange
- Whether there is a loft hatch, a shared roof or tricky access
Getting a price is simple: just phone 07833 053749 or drop us an email, let us know about the property and we will explain which survey suits. We confirm the price before anything is booked.

Checking the roof from ground level
What you cannot do safely is get up close. Slates, tiles, flat roofs and rooflights can give way. That’s where a survey comes in.
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. Please do not climb up for a closer look.
What we do, step by step
The visit has one job: to see as much of the flat roof as can safely be seen and record it clearly. Everything we note and photograph goes into the written report. It typically takes an hour or two for a house, and about three to four hours for a commercial roof. Somewhere as small as Stonehill, access is frequently the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- We start with the address and, on larger roofs, the roof area and access.
- We check the rooms or spaces under the roof for staining where there’s access.
- 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.
Preparing for the visit
- Have any questions written down, so nothing gets missed
- If you are buying, check with the agent that we can get in
- Tell us about any leaks, stains or damp patches you know of
Getting a price
Once you know what you need, phone 07833 053749 or drop us an email. We will suggest a package, agree the price and find a date.
Advice
Useful tips for Stonehill property owners
Some practical points come up on survey after survey. They’re worth knowing whatever the roof:
- Plan a survey before the covering reaches the end of its usual life
- Treat rooflights and old sheeting as fragile
- Check the outlets after the leaves fall
- Note where water lies after a downpour
Questions about the findings are always welcome. The Standard Survey includes a follow-up consultation and the Premium Survey an in-person consultation, so you can talk the findings through.
After heavy rain, look at the roof from an upstairs window if you can. Water still lying a day or two later is worth getting looked at.
What we can’t see
We only report whatever is safely visible on the day, so there are some things a survey can’t cover:
- What’s under the membrane without opening it up
- Whether the deck or joists are strong enough
- Asbestos testing, which needs a specialist asbestos surveyor
If you’re not sure which survey you need, call 07833 053749 or drop us an email and we’ll give you a straight answer. What a survey covers and doesn’t.

Your questions about flat roof surveys in Stonehill
Is Stonehill within the area you cover?
Yes, we do. We survey roofs across London and South East England, from towns to the smallest villages. Longer journeys are simply planned in advance.
Do you cover Stonehill?
Yes, Stonehill is one of the places we work. The survey and report are the same in Stonehill as anywhere else.
Can you give me structural calculations?
No. We note visible signs like sagging or deflection, but we do not carry out calculations or give an engineer’s opinion. Where an engineer is needed, we say so in the report.
I live in a flat. Can you survey the roof?
Yes, as long as access is agreed. Roofs over flats are often shared, so whoever owns or manages the building needs to agree access. We inspect only the parts we’re allowed to reach.
Will the survey show why my flat roof is leaking?
The survey covers the covering and all the details where leaks normally begin, recording anything that could let water through. Where the source is not obvious, a roof leak investigation or electronic leak detection may be the next step.
How soon will I get the report?
That depends on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day. The report is emailed to you.
What happens after the survey?
You’ll get the report by email, with photos and clear recommendations. The Standard Survey includes a follow-up consultation, and the Premium Survey an in-person consultation, so you can talk the findings through.
