How a flat roof survey works in Cow Roast
A flat roof leak often travels before it shows on the ceiling. It can run along the deck from a split, an open lap or a failed upstand some distance away. That’s why we check every detail across the roof, not only the area above the stain, with photographs of anything that could be letting water in. Whoever carries out the work then has a clear starting point. If you’re worried about blocked or damaged outlets and signs of deflection in the roof deck, a survey will tell you what’s going on, whatever the roof.
In a small place like Cow Roast, a flat roof can stand in the open, so edges, upstands and laps take a beating. 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.
Report times depend on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

Common questions in Cow Roast
Does a conservation area affect roof work in Cow Roast?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Do you cover smaller places like Cow Roast?
Yes, Cow Roast is covered. Our area covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
What does ponding on a flat roof mean?
Standing water a day or two after rain usually needs attention. The cause may be the outlets, the falls or the deck. We check each of these and record what we find.
How do I book a survey in Cow Roast?
The quickest way is to phone 07833 053749 or send us an email. Let us know the address and a little about the roof, and we will point you to the right survey. We survey on any day of the week.
Can you survey a shared roof?
Yes, once access has been agreed. Roofs over flats are frequently shared, so we need permission from the freeholder or managing agent. We can only inspect what we’re given access to.
Will you fly a drone over my roof?
Yes, where it is applicable. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and the airspace and weather are checked before every flight.
Will this cover the whole house?
No. Our survey covers the flat roof only. It is not a RICS Level 2 or 3 survey of the whole building, and it is not a structural engineer’s report. Many buyers use it alongside a building survey.
Should I look at the roof myself first?
Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it.
During heavy rain, look at the gutters from the ground or a window. Overflowing water can be a sign of a blockage or a gutter that has dropped.
Flat roof surveys around Cow Roast
Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Next to the main roofs there’s typically a flat roof somewhere, whether on an extension, a garage or a commercial unit. Historic houses such as Cholesbury Manor House, about 2.7 miles south-west, show how far back building in the area around Cow Roast goes. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first.
If you own a rental within reach of Tring station, a flat roof over a rented flat is easy to forget until the tenant reports a leak. For an older house near a landmark such as Church of St Bartholomew (church of England), any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof.

What we do, step by step
On the day, we start by asking what you’ve noticed and what you want to find out. We then inspect everything that can safely be seen. The survey typically takes about 1–2 hours at most homes; commercial roofs usually need 3–4 hours. In a small place like Cow Roast, access is typically the main thing to plan. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Visits can be on weekdays, Saturdays or Sundays.
- We start with the details: the address, the roof’s use and any leaks or stains.
- We look at the roof from wherever it can be seen safely.
- 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.
- You get a written report with photos and our recommendations.
Before the survey
- Make a note of anything you’d like us to look at
- If it isn’t your property yet, arrange access through the agent
- Unlock side gates and any roof access doors

Advice
Signs you need a flat roof survey in Cow Roast
Every flat roof covering has a working life. Around 15 to 20 years is common for felt, while EPDM frequently lasts 30 to 50 years and GRP up to about 30, although how well it was laid and looked after matters a great deal. We can tell you how your roof is doing, whatever its age.
People usually book a survey when they’ve noticed something like this:
- Cracked or split membrane
- Upstands pulling away from walls
- Standing water left after rain
- Dips that suggest the deck is deflecting
For site and facilities teams at buildings such as Tring School, schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks.
Choosing a roof surveyor
- How long they’ve been surveying roofs
- Whether the price includes VAT
- Which parts of the roof they’ll actually see
- Whether you get a written report with photos
Why get it checked now?
By the time a flat roof leak shows indoors, water has already passed through the roof build-up. We can pick up worn covering and failing details sooner, so you can plan the work rather than react to it. In a place like Cow Roast, a barn or garage roof left to fail puts whatever is inside at risk. A quick look before winter can save a lot.
A Basic Survey starts from £150, including VAT. Standard is from £250 and Premium from £400, both inc. VAT. We confirm the exact price before booking.
Why us?
- Clear package prices, inc. VAT
- Satisfaction rate of 98%
- An independent view of the roof
- PI and public liability insurance
