Flat roofs in Aldenham
In this part of the South East, older roofs are mostly slate or clay tile and many newer ones concrete tile, and flat-roofed additions turn up almost everywhere. Next to the main roofs there is usually a flat roof somewhere, whether on an extension, a garage or a commercial unit. About 2.5 miles north-west lies High Elms Manor, a reminder of how long the area around Aldenham has been built on. Older homes in the wider area often have features worth a closer look, such as lead valleys, tall stacks and roofs that have been patched over the years.
The streets around a church such as Church of St John the Baptist are frequently among the oldest in a place, and if you own one of the older houses nearby, any flat roof added at the back or on a dormer is likely to be far younger, and less durable, than the main roof. Shop and office owners around Harlequin Centre may find that outlets and upstands on commercial flat roofs are the places to check before trouble starts.

Flat roof surveys for homes and businesses in Aldenham
Our Basic Survey, from £150, gives you a visual inspection with photographs and written recommendations. For moisture detection and a structural check, the Standard Survey starts from £250. Moisture readings are useful on flat roofs, where water can spread under the covering before it shows inside. Larger commercial roofs are quoted for their size. We survey single-ply membranes, mastic asphalt and upstands and outlets, and common reasons people get in touch are blisters and bubbles in the covering and signs of deflection in the roof deck.
Flat roofs on exposed homes in small places like Aldenham take more wind and rain, which is hard on edges, upstands and joins in the covering. Felt roofs, which often last around 15–20 years, normally show it first. EPDM rubber and GRP coverings last longer, but their edges and joints still need checking. Exposed edges are usually the first part of a flat roof to go.
The report is written in plain words, so it makes sense without any roofing background. Each point is backed by a photo where possible, with the urgent items made clear.

Do you need a flat roof survey in Aldenham?
Ponding keeps the covering wet and wears it faster. Blocked outlets, poor falls and a sagging deck are the usual causes. Where trees are close by, leaves and silt can block an outlet within a single autumn.
Problems we come across frequently include:
- Failed upstands where the roof meets a wall
- Leaks around rooflights
- Pools of water lying on the roof
- Blisters and bubbles in the covering
For site and facilities teams at buildings such as Fair Field Junior School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.
What to check before booking

Different roofs, different checks
Felt and built-up roofs
The edges and upstands of a felt roof are typically where trouble starts. We check each one and photograph any that have split or pulled away.
EPDM rubber
Rubber roofs can shrink back from their edges or lift where the adhesive has failed. Any we find are noted and photographed.
Useful tips for Aldenham property owners
Getting the most from a flat roof survey starts before we arrive and carries on afterwards. Some tips:
- Look for standing water a day after rain
- Never stand on rooflights or fragile sheeting
- Clear roof outlets and gutters each autumn
- Book a survey every few years
Questions about the findings are always welcome. Standard Surveys come with a follow-up consultation, and Premium Surveys with an in-person one, so you can talk the findings through.
Clear leaves and silt from outlets and gutters, above all in autumn. A flat roof that drains well wears much more slowly.
Questions from Aldenham
Is my home in Aldenham listed or in a conservation area?
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. 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 carry out roof surveys in Aldenham?
Yes, Aldenham is one of the places we work. The survey and report are the same in Aldenham as anywhere else, and visits run on weekdays and weekends.
What does the report include?
Written findings with photos, explaining the condition of the flat roof, any defects and our recommendations, in order of urgency where relevant. The Standard Survey adds moisture detection and a structural check, and the Premium Survey adds thermal imaging, drone inspection where it applies and structural analysis.
How long is the visit?
Expect it to take roughly 1–2 hours for a small flat roof at home, and longer for a large commercial one. You will then get the report by email.
Can you survey any kind of flat roof?
We cover the main flat roof coverings: felt, asphalt, EPDM, GRP and single-ply. The report names the covering and explains its condition.
Will you photograph what you find?
Yes, plenty. Pictures sit next to the findings they show, which makes the report easy to follow.
What happens after the survey?
You’ll get the report by email. With Standard there’s a follow-up consultation; with Premium, an in-person consultation.
Can I check my roof myself?
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.
You can learn a lot from ground level. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Please don’t climb up for a closer look.
What we do, step by step
Time on site depends on the size and shape of the roof; as a rough guide, the survey takes about one to two hours on an ordinary house, rising to roughly 3–4 hours on a commercial building. If you have questions on the day, just ask. Around Aldenham, older homes can have small or awkward roof spaces, so it helps to know whether there is a loft hatch and how easy it is to reach. We only go where it’s safe.
- We start with the address and, on larger roofs, the roof area and access.
- Inside, we look for signs of water under the roof where we can reach.
- The roof is inspected from every safe viewpoint, without walking on fragile surfaces.
- Each defect is photographed and its likely cause noted.
- The report explains the condition and recommends what to do first.
Before we arrive
- Clear the way to the loft hatch
- Make a note of anything you’d like us to look at
- Note where any stains or damp appear
