How a flat roof survey works in Islip
A Basic Survey, from £150, covers a visual inspection, a condition report, photos and written recommendations. The Standard Survey, from £250, adds moisture detection and a structural check. On a flat roof, moisture readings can help show whether water has got under the covering. Bigger commercial roofs are priced on their size and access. We survey felt flat roofs, single-ply membranes and mastic asphalt, and people most often book us about splits and cracks in the covering and outlets that hold water back.
In a small place like Islip, a flat roof can stand in the open, 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.
We write the report in plain English, so it makes sense without any roofing background. Each point is backed by a photograph where possible, and recommendations are put by urgency where it matters.

Your questions about flat roof surveys in Islip
Will you come out to Islip?
Yes, smaller places are covered as well as towns. We work right across London and the South East. Let us know about access, parking and anything unusual about getting there when booking.
Do you cover Islip?
Yes. We survey roofs across London and the South East, and Islip is part of that. You can call 07833 053749 or send us an email with the address and a few details.
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.
What types of flat roof do you survey?
We cover the main flat roof coverings: felt, asphalt, EPDM, GRP and single-ply. The report names the covering and explains its condition.
Can you inspect my roof with a drone?
Yes, where it is applicable. We hold a CAA Flyer ID and Operator ID and fly a drone under 250g, and every flight depends on the airspace and the weather.
Does the weather affect the survey?
Light rain doesn’t typically stop a survey. Strong wind or a downpour can stop drone flights and make roof access unsafe, so if conditions are not right we will arrange another day with you.
How long will you be at the property?
Most surveys take about one to two hours for a small flat roof at home, and longer for a large commercial one. The report follows by email.
How the survey works
There isn’t much for you to do on the day. Point out anything you’ve noticed, such as stains, drips or loose pieces, and we will get on with the inspection. The survey itself takes an hour or two for a house; commercial roofs usually need 3–4 hours. Older rural homes like those around Islip can have a main roof, lower lean-to roofs and outbuildings all joined together. We work round each section in turn, from the safest viewpoints.
- First we go through the roof, what’s beneath it and any problems so far.
- We check the roof from the ground, windows and the roof where it is 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 questions written down, so nothing gets missed
- If you are buying, let the agent know when we are coming
- Note where any stains or damp appear

Flat roof surveys around Islip
Older buildings in west Oxfordshire often have Cotswold stone slate roofs, and some Oxfordshire villages still have thatch. 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’s typically a flat roof somewhere, whether on an extension, a garage or a commercial unit. With Holywell Manor about 4.6 miles south, Islip sits in an area with a long building history. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and the council can say whether a home is in a conservation area.
If you look after a building like Dr South's Church of England Primary School, schools and public buildings frequently have big flat roofs, and their outlets and upstands need regular checks. The streets around a church such as St Nicholas' Church are often among the oldest in a place, and if you own one of the older houses nearby, the flat roofs on later extensions tend to wear out long before the main roof. If you own a rental within reach of Islip station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

Roof by roof
Mastic asphalt
Mastic asphalt is a heavy, seamless covering often found on older blocks, balconies and commercial roofs. The survey checks for crazing, cracking, blistering and splits where the asphalt turns up the walls.
Felt and built-up roofs
The edges and upstands of a felt roof are typically where trouble starts. Every upstand and edge is checked, with photos of any that have lifted or cracked.
Can I check my roof myself?
Inside, the loft is a good place to look, with care. Take a torch and only step on boards or joists, checking for stains, damp wood or chinks of daylight.
Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry and it will help the survey.
