About our flat roof survey in Apsley
Ponding is often the first sign that something on a flat roof is not right. It can point to poor falls, a blocked outlet or a deck that is deflecting. The survey notes any ponding, the state of each outlet and any dips that hint at a sagging deck. If the deck itself looks like a structural concern, we will recommend a structural engineer. Typical surveys look at blisters and bubbles in the covering and gaps at upstands and abutments, on felt flat roofs, EPDM rubber and mastic asphalt.
Around a smaller place like Apsley, flat roofs normally cover extensions, garages and dormers. They’re small, but a leak over a kitchen extension can do a lot of harm. What it is covered in, and how well it was laid, decides what it needs. From an upstairs window, look for standing water, splits and edges coming away.
The report does not just list problems. It explains what we found, why it matters and what we recommend, so you can plan your next steps.

Your questions about flat roof surveys in Apsley
Does a conservation area affect roof work in Apsley?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. Listed building consent is needed for changes that affect a listed building’s special interest, and conservation areas can limit changes of roofing material.
Is Apsley within the area you cover?
Yes, smaller places are covered as well as towns. Our area covers London and South East England. Just mention lanes, gates or anything else about the route when booking.
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.
Will you check the loft?
Yes, where the survey calls for it and there’s safe access. We look for staining, damp, daylight and signs of movement, as far as the space allows.
Can you survey in bad weather?
A survey can usually go ahead in light rain, and it can even help show where water is getting in. Strong wind or heavy rain can stop drone flights and make roof access unsafe, so we’ll agree a new date if the weather isn’t suitable.
Can you test old roof sheets for asbestos?
We don’t carry out asbestos surveys. Older buildings, from before 2000, may have asbestos in cement sheets or soffits. Anything that might contain it is flagged, so a specialist asbestos surveyor can check before work starts.
How much does a flat roof survey cost in Apsley?
Prices start from £150, including VAT. We confirm the price for your survey before booking. For a price, call 07833 053749 or use the contact form.

Tips that help
From years of surveys, a few habits stand out as worth the effort:
- Keep records of when the roof was laid and what work has been done
- Book a survey every few years
- Make sure new fixings through the roof are properly sealed
- Treat rooflights and old sheeting as fragile
You get the report by email and can pass it to a roofer, your solicitor, the seller or your managing agent. It’s written in plain English, with a photograph of each defect, so anyone reading it can see what we saw.
Small defects are simpler to deal with while they’re still small. A flat roof that’s looked after between surveys usually lasts longer.
What we do, step by step
We photograph the roof as we go, so you can see in the report what we found and where. We take close-ups from wherever is safe, including by drone where it’s applicable and the weather allows. A typical visit takes about 1–2 hours at most homes, though large, tall or awkward roofs take more time. In a smaller place like Apsley, parking is seldom the issue; lanes, gates and long drives are worth mentioning. Low roofs on bungalows can often be seen well from ground level, and the loft shows the rest, while taller roofs may need other vantage points or the drone where applicable.
- We agree the roof to be surveyed, its use and any leaks you know about.
- We look at the roof from ground level, windows and the roof where it’s safe.
- We check the covering for splits, blisters, ponding and wear.
- We photograph and record the outlets, upstands, trims and rooflights.
- A written report with photos and recommendations is emailed to you.
Getting ready for the survey
- Have any paperwork from past roof work to hand
- Clear the way to the loft hatch
- Keep pets out of the way during the survey
Getting a price
Not sure which survey you need? The easiest way is to phone 07833 053749 or drop us an email and describe the roof and what’s worrying you. We will talk you through the options and what they cost.

What affects the cost of flat roof surveys
When we price a survey, we consider:
- Commercial roofs and larger buildings
- Extra roofs, like extensions, dormers or garages
- The roof’s overall size
- Whether thermal imaging or a drone is needed
A Basic Survey starts from £150, with VAT included. Standard is from £250 and Premium from £400, both inc. VAT. We confirm the price for your roof before you book.
Booking your survey
A little information up front helps. It helps to include:
- What kind of property and roof it is
- The reason for the survey, such as buying, a leak or storm damage
- Access details, such as a loft hatch or a shared roof
- Pictures of the roof from a safe spot, if you have them
Most bookings start with a short call: call 07833 053749 or email us and we’ll ask a few questions about the roof. The price is agreed before a date is set.
DIY checks: what’s safe
A DIY look is useful, but it is not a survey. From the ground, valleys, flashings and the backs of chimneys are often out of sight.
Inside, the loft is a good place to look, with care. Use a torch and stay on the joists or boards, checking for stains, damp wood or chinks of daylight.
Flat roof surveys in Apsley: local notes
Apsley is part of Hemel Hempstead, one of the post-war new towns. Many homes in the new towns date from the post-war decades, with concrete interlocking tiles, low-pitched roofs and flat-roofed garages and porches. Flat-roofed garages, porches and extensions from that era may have been re-covered more than once, or not at all. With High Elms Manor about 4.1 miles south-east, Apsley sits in an area with a long building history. If your house is among the older ones, expect a mix of original materials and later repairs on the roof, and any change of roofing material on a listed home needs checking with the council first.
If you own a rental within reach of Apsley station, a flat roof over a rented flat is easy to forget until the tenant reports a leak.
Apsley is about 1 mile south of Hemel Hempstead, in Hertfordshire. If you are in Apsley, booking works exactly as it does anywhere else: a call or an email, a price, then a date. Our Hertfordshire coverage includes Apsley. For surveys nearby, see our London page.

Local landmarks in Apsley

Signs you need a flat roof survey in Apsley
Water that does not drain sits on the roof and speeds up wear. It normally comes from poor falls, a blocked outlet or a deck that has dipped. Leaves and silt from nearby trees can soon choke an outlet.
Problems we come across frequently include:
- Loose or cracked edge trims
- Splits and cracks in the covering
- Blocked or damaged outlets
- Failed upstands where the roof meets a wall
Take a building like Two Waters Primary School: schools and public buildings often have big flat roofs, and their outlets and upstands need regular checks.
