Flat Roof Survey in Harpsden

How the survey changes by roof type
Felt and built-up roofs
On felt, the upstands and edge details often fail before the main surface. We check each one and photograph any that have split or pulled away.
Mastic asphalt
Asphalt has no laps, so its weak points are cracks and the skirtings at walls and upstands. We record any crazing or splits and where water may be getting in.
About our flat roof survey in Harpsden
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. You get a written report with photographs and our recommendations. We survey felt flat roofs, upstands and outlets and EPDM rubber, and the problems we are asked to look at most are raised blisters across the surface and outlets choked with leaves and silt.
Older buildings in small places like Harpsden may be listed or in a conservation area, and that can affect how an extension roof or dormer is re-covered. Check with the council before planning any change of material. Knowing the roof’s condition is the starting point. Changes that affect a listed building’s special interest need listed building consent.
Report times depend on the survey you book: Basic within 48 hours, Standard in 24–48 hours and Premium the same day.

Flat roof surveys around Harpsden
West Oxfordshire’s older buildings often carry Cotswold stone slates, and a few villages in the county keep their thatch. 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 a good many flat ones, over rear extensions, dormers, garages and shops. The wider area around Harpsden has a long history of building, with Greys Court about 2.8 miles north-west. Period homes nearby can have lead valleys, tall chimneys and a patchwork of past repairs, and the council can say whether a home is in a conservation area.
For an older house near a landmark such as Church of St Margaret, later flat-roofed additions are common on older houses, and their edges and upstands frequently show the first signs of wear. Hotels and guest houses near Harpsden cannot easily close rooms for a leak, so it pays to find faults before guests do.

Useful tips for Harpsden property owners
Nothing here needs a ladder. A few suggestions:
- Check new fixings through the roof are properly sealed
- Check the outlets after the leaves fall
- Note where water lies after a downpour
- Limit foot traffic on the covering
Questions about the findings are always welcome. Standard Surveys come with a follow-up consultation, and Premium Surveys with an in-person one, giving you a chance to go through what we found.
Try not to let a flat roof become a walkway. If access is needed, boards or walkways help protect the covering, and to keep well clear of rooflights and fragile sheeting.
What we do, step by step
Expect us to ask a few questions before we start, such as when any problem began and what work has been done before. Then the inspection itself takes about 1–2 hours for a house, rising to roughly 3–4 hours on a commercial building. In a small place like Harpsden, access is normally the main thing to plan. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Weekday and weekend visits are available.
- You let us know about the roof, its covering if you know it, and any leaks.
- The roof is inspected from safe viewpoints, and from the roof itself where that is safe.
- We check and photograph the covering, the falls, the upstands, the outlets, the trims and any rooflights.
- We check the rooms or spaces under the roof for staining where we can reach them.
- We send a written report with photos, the defects we found and what we recommend.
Before we arrive
- If it is not your property yet, arrange access through the agent
- Let us know about parking near the property
- For flats, check roof access has been agreed

FAQs for Harpsden
Does a conservation area affect roof work in Harpsden?
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, and councils can also use Article 4 directions.
Will you come out to Harpsden?
Yes, we do. Our area covers London and the South East, from towns to the smallest villages. Longer journeys are simply planned ahead of time.
Can you survey any kind of flat roof?
We survey felt and built-up roofs, mastic asphalt, EPDM rubber, GRP fibreglass and single-ply PVC and TPO. Not sure what yours is? We’ll tell you in the report.
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 if conditions aren’t right we’ll arrange another day with you.
Do I have to be there for the survey?
Someone needs to let us in if we’re looking inside or in the loft. Access is agreed with you as you book.
How quickly is the report sent?
That depends on the survey you book: the Basic Survey report arrives within 48 hours, the Standard Survey in 24 to 48 hours and the Premium Survey the same day. Reports are sent by email.
Can you give me structural calculations?
No. We point out what can be seen, such as sagging or deflection, but we do not carry out calculations or give an engineer’s opinion. Where an engineer is needed, we say so in the report.
Honest limits
Our survey is not a RICS Level 2 or Level 3 survey, a structural engineer’s report or an asbestos survey. It also has these limits:
- The condition of the deck or insulation hidden under the covering
- Testing older roof sheets for asbestos
- A fixed date for when the roof will need replacing
If you’re not sure which survey you need, ring 07833 053749 or send us an email and we’ll give you a straight answer. The full list of what we check.

- Mastic asphalt
- EPDM rubber
- Upstands and outlets
Do you need a flat roof survey in Harpsden?
Flat roofs take the full force of the weather on a surface that drains slowly. Over the years, coverings harden, crack and start to come away at the edges. People normally call us when a leak appears, before a purchase, or when the roof may be near the end of its life.
A survey makes sense if you’ve noticed:
- Ponding water that does not drain away
- Splits, cracks and crazing
- Upstands pulling away from walls
- Outlets choked with leaves and silt
For landlords with property near Henley-On-Thames station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.
Choosing a roof surveyor
- How they’ll see the roof: from the ground, the loft, the roof or by drone
- What experience they bring
- Which limits apply to the survey
- Whether VAT is in the quoted price
