Flat and commercial roofs around How Green
Across Kent, older roofs are often handmade clay or peg tiles, and tile-hanging on upper walls is a familiar sight. The county’s older buildings also include oast houses and timber-framed Wealden hall houses. Next to the main roofs there is usually a flat roof somewhere, whether on an extension, a garage or a commercial unit. Historic houses such as Hever Castle, about 0.7 miles south, show how far back building in the area around How Green goes. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and a listed home or one in a conservation area may need consent for changes of material.
If you let a flat or house near Hever station, the flat roof over a let home is worth a look before it becomes a tenant complaint. If you live in an older home near Church of St Peter, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. If you look after a building such as Hever Church of England Voluntary Aided Primary School, a large flat roof with lots of outlets and rooflights has many places where a membrane can fail.

Flat roof survey in How Green
Standing water is one of the first things we look for on a flat roof. It can mean the falls were never right, an outlet is blocked or the deck has started to sag. We record where water sits, check the outlets and look for dips that suggest deflection. If the deck itself looks like a structural concern, we’ll recommend a structural engineer. Common reasons to book are blistering in felt or asphalt and water getting in at rooflights, on GRP fibreglass, upstands and outlets and EPDM rubber.
Some older homes in villages like How Green are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. If you’re planning work, check with the council first. Finding out what state the roof is in gives you the facts to plan with. Listed building consent is needed for changes that affect a listed building’s special interest.
The written findings come by email, easy to pass on to a roofer, an agent or an insurer. Basic reports come within 48 hours, Standard within 24–48 hours and Premium on the day.

Useful tips for How Green property owners
A survey works best with a little help from you, before and after. Tips:
- Look for standing water a day after rain
- Keep people off the roof unless they need to be there
- Clear roof outlets and gutters each autumn
- Note any new marks on ceilings beneath the roof
Buyers can take the findings back to the seller or the agent. You might ask for work to be done before completion, or discuss the price, depending on what we found.
Keep foot traffic on a flat roof to a minimum. Where someone does need access, ask them to use boards or a protected route, and to keep well clear of rooflights and fragile sheeting.
The survey, step by step
We don’t take risks to get a closer look. We inspect whatever is safely visible, and anything we can’t see is noted in the report. The survey typically takes between one and two hours on an ordinary house, and more on a big or complicated roof. Rural addresses near How Green can be hard to find from a postcode alone, so a few directions are welcome. 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.
How to prepare
- Jot down any questions you want answered
- Agree roof access with the managing agent if it’s shared
- Leave side gates unlocked

Why it’s worth a survey now in How Green
Caught early, a split or open seam in a flat roof is often a small repair. Leave it, and water can get into the insulation and deck, which can turn a patch into a replacement. Surveying it now tells you where you stand. For an older or listed building in a place like How Green, repairs may need matching materials and consent, so leaving a defect until it’s urgent leaves less time to plan.
Simple, low roofs take less time to survey than tall or complicated ones, and the package you pick makes a difference too. The price is always agreed first.
Why book with us
- Independent findings on the roof’s condition
- 5,000+ roofs surveyed
- Visits on any day of the week
- More than 20 years surveying roofs

Questions from How Green
Do you cover How Green?
Yes. Our area covers London and South East England, and How Green is part of that. Just phone 07833 053749 or use the contact form and let us know about the property.
Will you come out to How Green?
We do. Villages and rural addresses get the same survey as a town house, with the route planned beforehand.
Should I worry about standing water on my flat roof?
Standing water on a flat roof deserves a closer look. It can point to blocked outlets, poor falls or a deck that is sagging, and it wears the covering faster. We record where it sits and the likely cause.
Do you carry professional indemnity insurance?
Professional indemnity and public liability insurance cover our surveys. Ask if you need details for a managing agent or building owner.
What types of flat roof do you survey?
Felt, asphalt, EPDM, GRP and single-ply roofs are all covered. If you do not know what your roof is, we’ll identify it on the day.
Which days do you carry out surveys?
Surveys can be booked for any day of the week: Monday to Friday, Saturdays and Sundays. Just let us know the days that suit you.
Can you find where water is getting through my flat roof?
We check the covering and every detail where leaks commonly start, and photograph anything that could be letting water in. If the source is hidden, we may suggest a leak investigation or electronic leak detection.
Surveys for landlords and agents in How Green
Letting agents can arrange access with tenants. Surveys run on any day of the week, which helps when tenants work during the week.
A roof problem in a let property affects your tenants as well as the building. A survey helps you spot issues early and plan the work.
How we price flat roof surveys
Our packages start from £150, including VAT. The price for your roof depends on:
- The height of the building and how the roof can safely be seen
- How big the roof is
- How complicated the roof is, with its valleys, chimneys and parapets
- Whether it is a home or a commercial building
One thing that affects the price is the package: from £150 for Basic, £250 for Standard and £400 for Premium, including VAT. Size, height and access can affect the price too.
Getting in touch
Before you get in touch, it helps to have:
- Your timetable, such as an exchange date
- Photos of the roof, taken safely from ground level or a window
- Whether there is a loft hatch, a shared roof or tricky access
- Where water is showing inside, if it is
Surveys can be booked for weekdays, Saturdays or Sundays. To arrange a day that suits you, ring 07833 053749 or send us an email with the address and the days you’d prefer.

What else we do in How Green
Should I look at the roof myself first?
After strong wind, take a look from the pavement or garden: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Don’t go up yourself.
A lot can be seen 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.
