Knockholt Pound Flat Roof Survey
A careful look at the flat roof at your property in Knockholt Pound, with photographs and a written report.
- Failed seals around rooflight kerbs
- Dips that suggest the deck is deflecting
- Raised blisters across the surface
Flat roof surveys for homes and businesses in Knockholt Pound
Each type of flat roof has its own weak points. Felt can blister and crack, asphalt can craze and split, EPDM seams and laps can lift, and GRP can crack where boards meet or at the trims. On PVC and TPO single-ply roofs, we look closely at the welded laps, edges and fixings. Once you know the covering and its condition, planning the next step is far easier. If you’ve noticed dips that suggest the deck is deflecting and pools of water lying on the roof, a survey will tell you what’s going on.
In a village or hamlet like Knockholt Pound, flat roofs are usually on extensions, garages, outbuildings or barn conversions. The checks are the same as anywhere: the covering, the edges, the upstands and where water drains away. We simply plan the journey and access in advance. If there are outbuildings or garages with flat roofs, mention them when you book.
After the visit, you get a written report with photos, sent by email. It sets out the condition of the flat roof, any defects and our written recommendations.

- How tall the building is and how easy the roof is to see
- Which survey package you book
- How many separate roofs there are, such as extensions, dormers and garages
- Roof area
One thing that affects the price is the package: Basic from £150, Standard from £250 or Premium from £400, all with VAT included. Size, height and access can affect the price too.

Flat roof surveys in Knockholt Pound: local notes
With Down House about 3.2 miles west, Knockholt Pound sits in an area with a long building history. Older roofs in the wider area can hide decades of patch repairs, so the detail matters. Older houses across Kent often have handmade clay or peg tiles, and many have tile-hung walls. Kent’s older buildings take in oast houses and timber-framed Wealden hall houses as well. Mixed in with those pitched roofs are a good many flat ones, over rear extensions, dormers, garages and shops.
If you let a flat or house near Knockholt station, the flat roof over a let home is worth a look before it becomes a tenant complaint. Anyone responsible for a site like Halstead Community Primary School will know that ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

Common roof problems in Knockholt Pound
Water that doesn’t drain sits on the roof and speeds up wear. Blocked outlets, poor falls and a sagging deck are the usual causes. Where trees are close by, leaves and silt can block an outlet within a single autumn.
A survey can pick up problems such as:
- Splits and cracks in the covering
- Edge trims that have lifted or split
- Outlets that hold water back
- Water getting in at rooflights
If you live in an older home near St Katharine's Church, the joins between later flat roofs and the old walls are where problems typically start.

When you need someone else
Without opening up the roof, some things stay hidden, so a survey has limits:

- Hidden layers beneath the covering
- Fragile surfaces, which we do not walk on

For landlords and managing agents
Managing agents and residents’ management companies use roof surveys to plan maintenance. The report sets out what needs attention now and what can wait, which helps with budgets and planning.
Letting agents can arrange access with tenants, at a time agreed in advance. We survey on any day of the week, which helps when tenants work during the week.
What we do, step by step
The aim of the visit is simple: 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 usually takes between one and two hours for a small flat roof at home, and longer for a large commercial one. Rural addresses near Knockholt Pound can be hard to find from a postcode alone, so a few directions, or a note of a nearby landmark, help us arrive on time. After that, the survey runs as it would anywhere.
- First we go through the roof, what’s beneath it and any problems so far.
- The roof is viewed from safe positions, including the roof itself where that is safe.
- We check the covering for splits, blisters, ponding and wear.
- Upstands, outlets, edge trims and rooflights are checked and photographed.
- A written report with photos and recommendations is emailed to you.
Before we arrive
- Jot down any questions you want answered
- Check the loft hatch can be reached
- Agree roof access with the managing agent if it is shared
How to book
Every survey is priced before it is booked, so you know where you stand. Prices start from £150, including VAT. To book, phone 07833 053749 or email us.
