What happens if roof problems are left?
On a commercial building, a flat roof leak can disrupt tenants, staff and stock. Surveying the roof in good time means work can be planned and budgeted around the people who use the building. For older village homes like those around Thong, the right replacement materials aren’t always easy to find quickly. That’s one more reason to find defects before they become urgent.
The Premium Survey includes thermal imaging and drone inspection where it applies, which starts from £400, inc. VAT. We can help you choose the package that fits what you’d like to know.

Flat roof surveys for homes and businesses in Thong
Flat roofs deal with rain in a very different way from pitched ones. Because rain sits on it for longer, a small split, an open seam or a blocked outlet matters more. The surface, the falls, the upstands and the trims are all looked at closely, and we note any sign that the deck below has got wet. The aim is to find problems before they show up as a stain on a ceiling. Common reasons to book are failed upstands where the roof meets a wall and ponding water that doesn’t drain away, across felt flat roofs, upstands and outlets and EPDM rubber.
In a village or hamlet like Thong, flat roofs are typically on extensions, garages, outbuildings or barn conversions. They need the same care as any town roof: the covering, the edges, the upstands and where water drains away. The journey and access are planned beforehand. If there are outbuildings or garages with flat roofs, mention them as you book.
Report times depend on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

What we are asked to look at in Thong
The surface of a flat roof heats up and cools down far more than the rooms below. That movement pulls at seams, laps and the joints between boards, which can open splits and cracks over the years. Older coverings that have lost their flexibility are the most likely to suffer.
A survey makes sense if you’ve noticed:
- Splits, cracks and crazing
- Blisters and bubbles in the covering
- Dips that suggest the deck is deflecting
- Upstands pulling away from walls
Anyone responsible for a site like Riverview Infant School will know that a large flat roof with lots of outlets and rooflights has many places where a membrane can fail.

How it works
We look at the roof from outside and, where it is relevant and there is safe access, from inside the roof 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 between one and two hours for most houses, or half a day or so for a commercial building. In a small place like Thong, access is typically the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Visits can be on weekdays, Saturdays or Sundays.
- First you give us the address, what the roof covers and any leaks you’ve noticed.
- We check the roof from wherever it can safely be seen.
- 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.
- We send a written report with photos, the defects we found and what we recommend.
Before we arrive
- Let us know about parking near the property
- For flats, make sure roof access has been agreed
- Buyers: confirm access with the estate agent or seller

Advice
Flat roof surveys around Thong
The coast is about 4 miles or less from Thong, and places near the sea get more salt in the air and more wind than inland. On a flat roof near the sea, edge trims and upstands take the brunt of the wind, and metal parts corrode faster. Cobham College, about 1.5 miles south, is one of the historic houses in the wider area around Thong. On older houses around here, roofs often 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.
If you live in an older home near Church of St Peter and St Paul, flat-roofed rear additions and dormers added over the years are worth checking. If you let a flat or house near Sole Street station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

Roof by roof
Felt and built-up roofs
The edges and upstands of a felt roof are typically where trouble starts. We check each one and photograph any that have split or pulled away.
Single-ply membranes
Plant, fixings and foot traffic can all damage a single-ply roof. Any tears, punctures or loose membrane are recorded with photos.
Landlord and commercial surveys in Thong
Shared roofs need a little more planning: we need access agreed with the freeholder or managing agent. Tell us about it when booking and we will plan the visit with that in mind.
With a portfolio of properties, you can book surveys for several addresses. To arrange surveys for several addresses, call 07833 053749 or email us.

Your questions about flat roof surveys in Thong
Will you come out to Thong?
Yes, smaller places are covered as well as towns. We cover the whole of London and South East England. Just mention lanes, gates or anything else about the route when booking.
Does being near the coast affect roofs in Thong?
Near the coast, roofs face more wind and more salt than further inland. Salt is hard on nails, clips and metal flashings, while strong wind lifts anything already loose.
Should I worry about standing water on my flat roof?
Ponding is worth looking into. It can point to blocked outlets, poor falls or a deck that is sagging, and water that sits wears the covering sooner. We record where it sits and the likely cause.
Do you look for flat roof leaks?
We check the whole roof, since water can travel before it shows inside. Splits, open laps, upstands, outlets and rooflights are all checked. If the cause cannot be seen, we’ll say so and suggest what would help.
What insurance do you have?
Every survey is covered by professional indemnity and public liability insurance.
Do I have to be there for the survey?
It depends on what we need to see. For inside areas and the roof space, someone has to give us access; we’ll agree the details when booking.
What’s the best way to book?
The quickest way is to call 07833 053749 or drop us an email. Let us know the address and a little about the roof, and we will take it from there. Surveys run on any day of the week.
