How a flat roof survey works in Great Offley
We inspect a flat roof from wherever it can be seen safely: from the roof itself where that is safe, from windows and nearby vantage points, and from inside where there is access. Fragile rooflights and fragile sheets are never walked on. If part of the roof can’t be seen or reached safely, the report says so, so the limits of the survey are clear. We are frequently asked to look into splits, cracks and crazing and blistering in felt or asphalt, across GRP fibreglass, mastic asphalt and EPDM rubber.
In a village or hamlet like Great Offley, flat roofs are typically on extensions, garages, outbuildings or barn conversions. They need the same care as any town roof: the covering, the edges, the upstands and where water drains away. The journey and access are planned beforehand. If there are outbuildings or garages with flat roofs, mention them as you book.
The report works through the roof section by section, from the main slopes down to the gutters and outlets, with a note and a photo for each point. It records what’s sound as well as what isn’t.

Flat roof surveys in Great Offley: local notes
Older buildings may be listed or sit in a conservation area. To find out, check Historic England’s list and ask the council about conservation areas. In either case, a change of roofing material may need consent. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Mixed in with those pitched roofs are lots of flat ones, over rear extensions, dormers, garages and shops.
If you look after a building like Offley Endowed Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. Landlords with a home close to Hitchin station may find that the flat roof over a let home is worth a look before it becomes a tenant complaint.
Great Offley is about 3 miles south-west of Hitchin, in Hertfordshire. We carry out flat roof surveys for homes and businesses in Great Offley and nearby. Great Offley is one of the towns and villages in Hertfordshire we cover for flat roof surveys. We also survey roofs in Milton Keynes.

Tips from our surveys
A survey works best with a little help from you, before and after. Tips:
- Plan a survey before the covering reaches the end of its usual life
- Clear roof outlets and gutters each autumn
- Keep people off the roof unless they need to be there
- Watch the ceilings below the flat roof for stains
If anything in the report isn’t clear, just ask us. The Standard Survey includes a follow-up consultation and the Premium Survey an in-person consultation, giving you a chance to go through what we found.
Book a survey every few years, and again after new fixings, units or rooflights go in. You will spot changes early and have a record to look back on.
Great Offley: your questions answered
Does a conservation area affect roof work in Great Offley?
We can’t confirm that for you, but Historic England’s list and your council can. Both listing and conservation areas can limit changes of roofing material, and councils can also use Article 4 directions.
Will you come out to Great Offley?
Yes, Great Offley is covered. We cover the whole of London and South East England, from towns to the smallest villages. The journey is planned ahead, so it’s useful to know about access.
When does the report arrive?
Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. Each one is emailed.
How many years has my flat roof got left?
We don’t put a figure on it. Typical ranges are around 15 to 20 years for felt, 30 to 50 for EPDM and up to about 30 for GRP, but the report tells you how your roof is really doing.
Is ponding on a flat roof a problem?
Water that lies on a flat roof for days is a sign that something needs attention. The cause may be the outlets, the falls or the deck. The survey looks at each and records the likely cause.
Do you check flat roofs for asbestos?
We don’t carry out asbestos surveys. Buildings built or refurbished before 2000 may contain asbestos, for example in cement roof sheets. We note anything that could contain it, and a specialist asbestos surveyor should check it before it is disturbed.
Is it a structural engineer’s report?
No. We are roof surveyors, not structural engineers, and it does not include calculations. If we see signs that need an engineer’s opinion, we’ll recommend one.
The survey, step by step
Before we start, tell us why you’ve booked: buying, a leak, storm damage, new work or just wanting to know where things stand. That way we can focus on what matters to you. The visit usually takes about 1–2 hours on an ordinary house, with bigger or more complicated roofs taking longer. Older roofs in small places like Great Offley can have low, tight loft spaces, so it helps to know whether there is a loft hatch and how easy it is to reach. Only areas that can be reached safely are inspected.
- We agree the roof to be surveyed, its use and any leaks you know about.
- The roof is viewed from safe positions, including the roof itself where that is safe.
- The covering is checked for wear, splits, blisters and standing water.
- Upstands, outlets, edge trims and rooflights are checked and photographed.
- The report, with photographs and recommendations, comes to you by email.
Getting ready for the survey
- Agree roof access with the managing agent if it is shared
- Keep pets inside or away from the areas we’re looking at
- Have keys ready for side gates, garages or roof access doors

What affects the price in Great Offley
Several things affect the price of a survey:
- The shape of the roof and its details
- If the survey needs thermal imaging or a drone
- Which survey package you book
- The roof’s overall size
One thing that affects the price is the package: Basic from £150, Standard from £250 or Premium from £400, all including VAT. The roof’s size, height and access matter as well.
Booking your survey
To price your survey accurately, we will ask about:
- Any deadline, such as an exchange date
- The type of building and roof, such as pitched or flat
- What made you get in touch
- The address and postcode of the property
A quick phone call is typically the easiest start: call 07833 053749 or drop us an email, and we’ll ask about the building and what you need. The price is agreed before a date is set.
What we are asked to look at in Great Offley
Flat roofs swing between hot and cold more than most parts of a building. This constant movement works at laps, seams and board joints, which can open splits and cracks over the years. Older coverings that have lost their flexibility are the most likely to suffer.
Here are some of the things we see frequently:
- Leaks around rooflights
- Signs of deflection in the roof deck
- Standing water left after rain
- Outlets choked with leaves and silt
If you own one of the older houses in the streets near Church of St Mary Magdalene, the flat roofs on later extensions tend to wear out long before the main roof.
Before you book any roof surveyor
- Whether you get a written report with photos
- What they won’t be able to tell you
- Whether any drone flown is registered with the CAA
- Which parts of the roof they’ll actually see

Leave it or get it looked at?
A survey can show whether a whole new roof is needed or whether the problems are in a few places. Sometimes a few details are to blame, and sometimes the covering has simply had its day. Our report gives you the evidence to discuss with a roofer. Older cottages and farmhouses around Great Offley can have roof timbers that have been there a very long time, where water from a failed roof can cause rot if it is left.
There are three survey packages: the Basic Survey from £150, the Standard Survey from £250 and the Premium Survey from £400, with VAT included. The price for your roof depends on its size, access and what you’d like to know.
