Your questions about flat roof surveys in Higher Denham
Do you carry out roof surveys in Higher Denham?
Yes, Higher Denham is one of the places we work. Every survey there gets the same written report with photographs.
How do I find out if my home in Higher Denham is listed?
Your council is the best source, with Historic England’s list for listed buildings. A change of roofing material may need consent in either case.
Can you survey a shared roof?
Yes, if whoever owns or manages the building agrees access. We look at the parts we’re given access to.
Do you look for flat roof leaks?
We check the whole roof, since water can travel before it shows inside. Splits, open laps, upstands, outlets and rooflights are all checked. Where nothing visible explains the leak, the report says what to try next.
Does the survey cover asbestos?
Our survey doesn’t include asbestos testing. Buildings built or refurbished before 2000 may contain asbestos, for instance in cement roof sheets. Anything that might contain it is flagged, so a specialist asbestos surveyor can check before work starts.
Do you need to get into the loft?
If it’s needed and safe to reach, yes. We look for staining, damp, daylight and signs of movement.
Is it a structural engineer’s report?
No. Our survey isn’t a structural engineer’s report, and it does not include calculations. If we see signs that need an engineer’s opinion, we’ll recommend one.
Flat roof survey in Higher Denham
A flat roof survey looks at the covering, the edges, the outlets and the details where the roof meets walls and rooflights. Felt, asphalt, EPDM, GRP and single-ply PVC or TPO roofs are all part of the work. It suits a small roof over an extension or garage as well as a large one over flats, offices or units. The findings go into a written report with photos, setting out the defects and what we’d recommend. We’re often asked to look into ponding water that doesn’t drain away and dips that suggest the deck is deflecting, across GRP fibreglass, mastic asphalt and upstands and outlets.
Some older homes in villages like Higher Denham are listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. If you are planning work, check with the council first. Finding out what state the roof is in gives you the facts to plan with. Changes that affect a listed building’s special interest need listed building consent.
Every survey ends with a written report, with photographs, emailed to you. It sets out the condition of the flat roof, any defects and our written recommendations.

For landlords and managing agents
Shared roofs need a little more planning: we need access agreed with whoever owns or manages the building. Tell us about it when booking and we’ll plan the survey around it.
Managing agents and residents’ management companies use roof surveys to plan maintenance. Recommendations are set out by urgency where it matters, which helps when budgeting.
Before and after the survey
There is plenty you can do without going near the roof. What helps most:
- Note where water lies after a downpour
- Note any new marks on ceilings beneath the roof
- Keep clear of rooflights and fragile roof sheets
- Keep people off the roof unless they need to be there
Buyers can take the findings back to the seller or the agent. You might ask for work to be done before completion, or discuss the price, depending on the findings.
Try not to let a flat roof become a walkway. Where someone does need access, ask them to use boards or a protected route, and remind them never to step on rooflights or fragile sheets.
Flat roof surveys around Higher Denham
Some villages in Buckinghamshire still have thatched roofs. Slate and clay tile are the usual coverings on older South East houses, with concrete tiles on many later estates. Flat roofs on extensions, dormers, garages and business units are found alongside them almost everywhere. The wider area around Higher Denham has a long history of building, with Ickenham Hall about 3.6 miles east. Older roofs in the wider area can hide decades of patch repairs, so the detail matters.
If you look after a building such as Denham Green E-Act Primary Academy, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly. If yours is one of the older homes in the streets near St Mark's Hall, later flat-roofed additions are common on older houses, and their edges and upstands often show the first signs of wear. If you run a business near The Pavilions, the flat roofs over shops and commercial units are worth checking before a leak, not after.

How we price flat roof surveys
The price reflects the time and kit the roof needs. The main factors are:
- Which survey package you book
- How complicated the roof is, with its valleys, chimneys and parapets
- Extensions, dormers and garages with roofs of their own
- Commercial roofs and larger buildings
A small, low roof with good viewpoints takes less time than a tall, complicated one, and the package matters as well. The price is always agreed first.
What we need to know
Before you get in touch, it helps to have:
- The reason for the survey, such as buying, a leak or storm damage
- How the loft is reached, if there is one
- The kind of building and roof involved
- Your postcode, so we can check access and travel
Booking is simple: just ring 07833 053749 or drop us an email, tell us about the property and we’ll suggest the right survey. The price is agreed up front.
Different roofs, different checks
Single-ply membranes
Many offices, units and newer flats have a single-ply PVC or TPO roof. We check the welded laps, the edges, the fixings and any punctures.
Felt and built-up roofs
On felt, the upstands and edge details frequently fail before the main surface. We check each one and photograph any that have split or pulled away.

What else we do in Higher Denham
What we cannot see
Without opening up the roof, some things stay hidden, and that sets some limits:
- Whether the deck or joists are strong enough
- What’s under the membrane without opening it up
- Asbestos testing, which needs a specialist asbestos surveyor
If in doubt, phone 07833 053749 or send us an email and we’ll suggest the right survey. The full list of what we check.

How the survey works
It helps to start with what’s prompted the survey: a purchase, a leak, a storm, new work or simply peace of mind. That way we can focus on what matters to you. The visit usually takes roughly 1–2 hours for most houses, and longer for a large or complex roof. In a small place like Higher Denham, access is normally the main thing to plan. Mention any outbuildings, barns or garages you want included, and anything about the roof you already know. Visits can be on weekdays, Saturdays or Sundays.
- You tell us about the roof, its covering if you know it, and any leaks.
- We view the roof from ground level, from windows and from the roof where it’s safe to do so.
- Every part of the roof we can see is looked at: covering, falls, upstands, outlets, trims and rooflights.
- Inside, we look for damp and staining under the roof where there’s access.
- You get a photo-illustrated written report and our recommendations.
How to prepare
- Check the loft hatch can be reached
- For flats, make sure roof access has been agreed
- Tell us about any leaks, stains or damp patches you know of

Photos help, if you have them. Pictures from the ground or a window are fine; never climb up to get a better view. To get started, call 07833 053749 or use the contact form.
