Flat roof survey in Great Wymondley
Water through a flat roof doesn’t always come in where the stain is. It can run along the deck from a split, an open lap or a failed upstand some distance away. Our survey covers the whole roof, not just the part above the mark, and photograph anything that could let water in. A roofer can then start from a clear picture of the problem. We survey upstands and outlets, GRP fibreglass and single-ply membranes, and the problems we are asked to look at most are splits, cracks and crazing and a sagging deck under the covering.
Flat roofs on exposed homes in small places like Great Wymondley take more wind and rain, which is hard on edges, upstands and joins in the covering. Older felt roofs, often 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.
Every survey ends with a written report, with photos, emailed to you. It explains the condition of the flat roof, the defects we found and what we recommend.

Flat roof surveys in Great Wymondley: local notes
Historic houses such as Knebworth House, about 4.9 miles south, show how far back building in the area around Great Wymondley goes. Older homes in the wider area frequently have features worth a closer look, like lead valleys, tall stacks and roofs that have been patched over the years, and a listed home or one in a conservation area may need consent for changes of material. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Next to the main roofs there is typically a flat roof somewhere, whether on an extension, a garage or a commercial unit.
Take an older house close to Church of St Mary the Virgin: the joins between later flat roofs and the old walls are where problems usually start. If you look after a building such as Wymondley Junior Mixed and Infant School, ponding and blocked outlets on a wide flat roof are worth catching before the next wet season. Landlords with a home close to Hitchin station may find that a flat roof over a rented flat is easy to forget until the tenant reports a leak.

How it works
We’ll ask a few questions first, such as when any problem began and what work has been done before. Then the inspection itself takes roughly 1–2 hours at most homes; commercial roofs usually need 3–4 hours. Cottages and farmhouses around Great Wymondley often have roofs at several levels, with lean-tos and outbuildings attached. Each part is looked at from wherever it can be seen safely, and anything we cannot see is noted.
- We start with the details: the address, the roof’s use and any leaks or stains.
- The roof is inspected from safe viewpoints, and from the roof itself where that’s safe.
- Every part of the roof we can see is looked at: covering, falls, upstands, outlets, trims and rooflights.
- We check the rooms or spaces under the roof for staining where we can reach them.
- You get a written report with photos and our recommendations.
How to prepare
- Clear the way to the loft hatch
- Leave side gates unlocked
- For a flat or shared roof, check access with the freeholder or managing agent

Related advice
Different roofs, different checks
Rooflights and upstands
Upstands at walls and parapets need to stay watertight as the building moves. We check for splits, gaps and loose flashings above the upstand.
GRP fibreglass
A well-laid GRP roof frequently lasts up to about 30 years. Cracking where boards meet or where the deck moves is a common early sign of trouble.
Can I check my roof myself?
Your own check is a good start, but it isn’t a survey. You will not see flashings, valleys or the backs of chimneys properly from the ground.
It is useful to keep a record: dates of leaks, photos from the ground and any work done on the roof. Share it with us when booking and it will help the survey.

Will I get photos?
Yes, plenty. Each finding is shown in a picture where possible.
Do you need to get into the loft?
Yes, where the survey calls for it and there’s safe access. Inside, we look for damp, staining, gaps and sagging, as far as the space allows.
Do you cover flat roofs on blocks of flats?
Yes. We survey flat roofs on commercial buildings as well as homes. Expect about 3 to 4 hours on site for most commercial roofs, with larger roofs quoted on their size.
What this survey cannot tell you
Without opening up the roof, some things stay hidden, and that sets some limits:
- Asbestos testing, which needs a specialist asbestos surveyor
- Whether the deck or joists are strong enough
- An exact number of years the roof has left
