Flat roof survey in Astwick: what you get
If the house you’re buying has a flat roof on an extension, dormer or garage, it is worth knowing its condition before exchange. Many felt roofs need renewing after around 15 to 20 years, and EPDM and GRP frequently go on for longer. We set out the type of covering, its condition and the defects we found, with a photo of every defect. You then have something specific to put to the seller or agent. We survey single-ply membranes, EPDM rubber and upstands and outlets, and common reasons people get in touch are water getting in at rooflights and outlets choked with leaves and silt.
Flat roofs on exposed homes in small places like Astwick take more wind and rain, which is hard on edges, upstands and joins in the covering. Older felt roofs, frequently around 15–20 years in life, show it first. Rubber and GRP last longer, though trims and joints still need a look. Exposed edges are usually the first part of a flat roof to go.
We write the report in plain English, so it makes sense without any roofing background. Photos show what each point refers to, and recommendations are put in order of urgency where relevant.

When to book a survey in Astwick
A buyer’s general survey often recommends a closer look at a flat roof. Building owners and managing agents book to plan maintenance, or before a sale or a new lease. Either way, you get a clear record of the roof, with photos.
These are some of the problems a survey can pick up:
- A sagging deck under the covering
- Damaged trims at the roof edge
- Failed seals around rooflight kerbs
- Ponding water that doesn’t drain away
If you own one of the older houses in the streets near Church of Saint Guthlac, later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear.
What to check before booking
- Whether you get a written report with photos
- How soon the report will arrive
- Whether the loft is part of the inspection
- Their insurance cover
Flat roof surveys in Astwick: local notes
With Hinxworth Place about 1.7 miles east, Astwick sits in an area with a long building history. If you own one of the older houses, expect a mix of original materials and later repairs on the roof, and a listed home or one in a conservation area may need consent for changes of material. Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles, and flat-roofed additions turn up almost everywhere. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere.
If you own a rental within reach of Arlesey station, flat roofs on let property tend to be checked only when they fail, which is the costly way round. For site and facilities teams at buildings such as St Mary's CofE Academy Stotfold, a large flat roof with lots of outlets and rooflights has many places where a membrane can fail.
Astwick is about 1 mile north of Stotfold, in Hertfordshire. If you are in Astwick, booking works exactly as it does anywhere else: get in touch, agree the price and pick a day. Astwick is one of the places in Hertfordshire where we work. Milton Keynes is in our area too.

Roof by roof
GRP fibreglass
GRP can crack if the deck beneath flexes or if the resin was laid too thin. Our report notes cracks and any sign that the deck is flexing.
EPDM rubber
Rubber roofs can shrink back from their edges or lift where the adhesive has failed. We record any we can see, with photos.
What happens if roof problems are left?
Flat roofs can’t typically be seen from the street, so they’re often overlooked. Owners frequently learn the roof is at the end of its life only when it leaks. A survey every few years stops that from catching you out. In a place like Astwick, a barn or garage roof left to fail puts whatever is inside at risk. A quick look before winter can save a lot.
Price depends partly on the package: from £150 for Basic, £250 for Standard and £400 for Premium, including VAT. Size, height and access can affect the price too.

Useful tips for Astwick property owners
Most of what helps is simple and safe from the ground. A few suggestions:
- Book a survey every few years
- Check ceilings under the roof for damp patches
- Treat rooflights and old sheeting as fragile
- Clear roof outlets and gutters each autumn
You can use the report to ask roofers to quote for the same work. With each roofer working from the same list, comparing quotes is simpler. It’s your choice who carries out the work and when.
Try not to let a flat roof become a walkway. If access is needed, boards or walkways help protect the covering, and remind them never to step on rooflights or fragile sheets.
FAQs for Astwick
Does a conservation area affect roof work in Astwick?
We cannot confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case, and councils can also use Article 4 directions.
Do you carry out roof surveys in Astwick?
Yes, Astwick is within the area we cover. We cover the whole of London and South East England. Just phone 07833 053749 or drop us an email and let us know about the property, and we’ll talk through which survey suits.
Can you survey in bad weather?
Light rain is usually fine; heavy rain and wind are different. Strong wind or a downpour can make access unsafe and ground a drone, and we’d agree another day.
What insurance do you have?
Our cover is professional indemnity plus public liability, and details are available on request.
Do you give a life expectancy for the roof?
We do not give a fixed number of years, because it depends on upkeep, weather and how the roof was laid. Our report describes the condition and what needs doing, and when.
Can you find where water is getting through my flat roof?
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 will say so and suggest what would help.
How long have you been surveying roofs?
Over 5,000 surveys so far, across 20+ years of surveying roofs, with 98% customer satisfaction.
What affects the price in Astwick
Prices always include VAT. The things that change the price are:
- Any need for thermal images or a drone flight
- Building height and the viewpoints available
- Whether it’s a home or a commercial building
- How complicated the roof is, with its valleys, chimneys and parapets
To find out what your survey will cost, phone 07833 053749 or drop us an email with the address and some details. The price is agreed before a date is set.
What to let us know when you contact us
There’s no need for technical words. Just let us know:
- Pictures from the garden or a window, if you have them
- Why you want a survey: buying, a leak, a storm or new work
- Any stains, drips or damp patches you’ve seen indoors
- The kind of building and roof involved
Not sure which survey you need? The easiest way is to phone 07833 053749 or use the contact form and describe the roof and what’s worrying you. We’ll explain the options and the price.
How it works
Expect us to ask a few questions before we start, about the roof’s history, any leaks and past repairs. Then the inspection itself takes between one and two hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. In a hamlet or village like Astwick, a postcode does not always lead to the right gate, so a few directions are welcome. After that, the survey runs as it would anywhere.
- You send us the address and, for commercial roofs, an idea of the roof’s size.
- We check the rooms or spaces under the roof for staining where there is access.
- The roof is inspected from every safe viewpoint, without walking on fragile surfaces.
- Each defect is photographed and its likely cause noted.
- You get a report setting out the condition and our recommendations, in order of urgency.
Getting ready for the survey
- Gather any invoices or paperwork from past roof work
- Have any questions written down, so nothing gets missed
- Let us know about any leaks, stains or damp patches you know of
Getting a price
Buyers should book once an offer has been accepted, so there’s time to use the report before exchange. Otherwise, simply call 07833 053749 or email us whenever suits you.
