Flat roof surveys for homes and businesses in Aspenden
Each type of flat roof has its own weak points. Felt can blister and crack, asphalt can craze and split, EPDM seams and laps can lift, and GRP can crack where boards meet or at the trims. On PVC and TPO single-ply roofs, we look closely at the welded laps, edges and fixings. Once you know the covering and its condition, planning the next step is far easier. If you’re worried about a sagging deck under the covering and cracked or split membrane, we can find out what’s behind it, whatever the roof.
Flat roofs on exposed homes in small places like Aspenden take more wind and rain, 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.
The report records the flat roof as we found it on the day. That makes it useful now and a handy reference later, such as when you want to compare after future work.

Questions from Aspenden
How do I find out if my home in Aspenden is listed?
Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.
Is Aspenden in the area you cover?
Yes, Aspenden is within the area we cover. We cover the whole of London and South East England. Just ring 07833 053749 or send us an email and let us know about the property.
I live in a flat. Can you survey the roof?
Yes, once access has been agreed. The roof of a block or converted house is frequently shared, so the freeholder or managing agent needs to agree access. We can only inspect what we are given access to.
Do you need to get into the loft?
If the survey needs it and the loft space can be reached safely, yes. Please clear anything stored under the hatch, and if the loft can’t be reached safely, the report says so.
Does the survey cover asbestos?
Our survey doesn’t include asbestos testing. 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.
Do you carry professional indemnity insurance?
We hold professional indemnity and public liability insurance.
How much does a flat roof survey cost in Aspenden?
Prices start from £150, including VAT. You’ll know the price for your roof before booking, and it depends on the roof’s size, access and the package you choose. For a price, ring 07833 053749 or send us an email.
Flat roof surveys around Aspenden
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 is usually a flat roof somewhere, whether on an extension, a garage or a commercial unit. What can be done to an older roof may depend on listing or a conservation area. Your council and Historic England’s list will tell you where you stand, ideally before any re-roofing is planned.
Anyone responsible for a site like Millfield First and Nursery School will know that ponding and blocked outlets on a wide flat roof are worth catching before the next wet season.

Common roof problems in Aspenden
Flat roofs swing between hot and cold more than most parts of a building. That movement pulls at seams, laps and the joints between boards, which can open splits and cracks over the years. Coverings that have hardened with age tend to suffer most.
A survey can pick up problems such as:
- Raised blisters across the surface
- Ponding water that doesn’t drain away
- Gaps at upstands and abutments
- Outlets that hold water back
If you own one of the older houses in the streets near Parish Church of St Mary, the joins between later flat roofs and the old walls are where problems normally start.
What to check before booking
- Their track record with similar roofs
- Will they check the loft as well as the outside?
- Do they have a CAA Flyer ID and Operator ID for drone work?
- Whether you can ask questions once you have the report
What happens on the day
The visit usually starts outside and finishes in the loft: outside views come first, then the loft space if there’s safe access. All told, expect roughly 1–2 hours for an extension, garage or dormer roof, and around 3–4 hours for a commercial flat roof. Somewhere as small as Aspenden, access is often the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Weekday and weekend visits are available.
- 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 photos and recommendations, comes to you by email.
Before the survey
- Show us where any leaks or stains appear
- If the roof is shared, arrange access with whoever manages the building
- Leave side gates unlocked

Tips that help
Some practical points come up on survey after survey. They apply to most roofs:
- Ask whoever fits equipment on the roof to make good the covering
- Keep records of when the roof was laid and what work has been done
- Limit foot traffic on the covering
- Note any new marks on ceilings beneath the roof
If you’re buying, the report gives you something specific to take back to the seller or agent. You might ask for work to be done before completion, or discuss the price, depending on what we found.
Small defects are simpler to deal with while they’re still small. A flat roof that’s looked after between surveys normally lasts longer.
