Thermal roof surveys in Keynor Estate

About our thermal roof survey in Keynor Estate

Flat roofs over extensions, garages, flats and commercial buildings are where thermal imaging often helps most. It can show patterns that point to trapped moisture under the membrane. Pitched roofs with slates or tiles are frequently harder to read, because of the air space beneath, so we combine the camera with an inspection from the loft where there’s safe access. If you’re worried about areas of a flat roof that may hold water and missing or slipped insulation, we can find out what’s behind it.

Somewhere as small as Keynor Estate, older roofs are often steep and partly hidden by trees or outbuildings. Close-up drone photos and thermal images help show what cannot be reached safely. Both the forecast and the airspace are checked first, and the journey is planned ahead of time. Older roofs with steep slopes and tall chimneys are where the extra view helps most.

Findings are set out part by part, from the main slopes down to the gutters and outlets. It records what’s sound as well as what is not.

How it works

Once we’ve finished looking, we write up our findings as a written report with photos, emailed to you. On timing, it usually takes roughly 1–2 hours for most homes, plus time to check any thermal findings with moisture readings. In a hamlet or village like Keynor Estate, a postcode does not always lead to the right gate, so a few directions are welcome. The visit itself is the same as anywhere else.

  1. We start with the roof, its history and any signs of damp or heat loss.
  2. We check the conditions and note how they may affect the images.
  3. We inspect the roof and take thermal images during the same visit.
  4. Moisture readings are used to check what the camera shows.
  5. The Premium report reaches you the same day, and we go through it with you in person.

Preparing for the visit

  • If you are buying, check with the agent that we can get in
  • Make sure we can get to the back of the property
  • For flats, check roof access has been agreed

Related advice

Should I look at the roof myself first?

Watch the gutters in a downpour, from a window or the ground. Water spilling over the edge can point to a blockage or a sagging run.

Fresh stains on ceilings or walls after rain are worth noting. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.

Leave it or get it looked at?

Without thermal imaging, the only way to see how far water has spread is frequently to open up the roof. It helps when deciding whether to patch an area or replace the roof. Where a roof is exposed, as many are in small places like Keynor Estate, driving rain gets into any weakness, and older walls, once damp, take a long time to dry.

Prices start from £400, including VAT. Basic starts from £150, Standard from £250 and Premium from £400, VAT included, and we can help you choose.

Landlord and commercial surveys in Keynor Estate

A roof problem in a let property affects your tenants as well as the building. A survey shows what needs attention, so you can plan the work.

An agent can book and manage the survey for a landlord, and the report can go to both. We agree a time with the tenant beforehand.

What a thermal roof survey looks like in Keynor Estate

Keynor Estate lies within about 2 miles of the sea. Calm, dry conditions after a sunny day suit thermal imaging best, so the visit is planned around the forecast. An older home may be listed, or stand in a conservation area. Historic England’s list shows listed buildings, and the council can say whether a street is in a conservation area. In either case, a change of roofing material may need consent.

Take a building like Sidlesham Primary School: thermal images can show where wet insulation sits under a big flat roof. If your house is among the older ones in the streets near St Mary Our Lady Sidlesham, older roofs can be steep and hard to see from the street, which is where photos from the air and thermal images help.

Keynor Estate is about 2 miles north of Selsey, in West Sussex. Keynor Estate gets the same service as everywhere else we work: a careful look at what can safely be seen, photos and a clear written report. Across West Sussex, we cover Keynor Estate. Our Portsmouth page covers surveys nearby.

Surveys in PO20 work the same way as everywhere else we cover. Local streets include Chalk Lane and Cow Lane. Neighbouring places we cover for thermal roof surveys include Sidlesham (1 mile north-east), Street End (1 mile north), Church Norton (2 miles south-east), Sidlesham Common (2 miles north) and Pagham (2 miles east).

Practical tips

These tips come from what we see on roofs every week, before and after a survey:

  • Take photos of stains as they appear, so we can compare
  • Ask us about the forecast if rain is expected
  • Check from the ground or a window, never by climbing
  • Do not switch the heating off before the visit

You can pass the report to a roofer so they can see where the problem areas seem to be. Each thermal image is matched to a normal photo, so the areas are easy to locate.

Watch for new damp patches on ceilings beneath the roof. Early action keeps insulation from staying wet.

Prices for thermal roof surveys in Keynor Estate

Our packages start from £150, inc. VAT. The price for your roof depends on:

  • How big the roof is
  • Basic, Standard or Premium
  • The shape of the roof and its details
  • If the survey needs thermal imaging or a drone

The cost of a survey depends on the roof: how big it is, how high it is, the number of separate roofs and how it can be reached and seen safely. Our price is from £400, including VAT.

What we need to know

A little information up front helps. It is useful to include:

  • Your timetable, like an exchange date
  • The kind of building and roof involved
  • Access details, such as a loft hatch or a shared roof
  • Where water is showing inside, if it is

If you are buying, it is useful to book soon after your offer is accepted, so you have the findings in time to act on them before you exchange. Otherwise, simply ring 07833 053749 or drop us an email whenever suits you.

Questions from Keynor Estate

Will you come out to Keynor Estate?

Yes, Keynor Estate is covered. We survey roofs across London and South East England, and smaller places are part of that. Longer journeys are simply planned in advance.

Is Keynor Estate in the area you cover?

Yes, Keynor Estate is one of the places we work. Every survey there gets the same written report with photos, and visits run on weekdays and weekends.

How long is the visit?

That depends on the size and shape of the roof, but most surveys take between one and two hours for a house, though large, tall or awkward roofs take more time. The written report follows by email.

Can you inspect my roof with a drone?

Where it helps and the rules allow, yes. Our sub-250g drone is flown by a CAA-registered operator with a Flyer ID and Operator ID, and the airspace and weather are checked before every flight.

Does thermal imaging work on slate and tile roofs?

It can help, but the results are often less clear than on a flat roof. Slates and tiles over a ventilated space can mask what’s below, so we combine it with an inspection from the loft where there is safe access.

What will the report tell me?

It sets out what we found, why it matters and what we recommend, backed by photographs. Anything we couldn’t see safely is noted too, so you know exactly what was covered.

Is this an asbestos survey?

No. Our report may flag materials that could contain asbestos, but only a specialist asbestos surveyor can confirm it. It may be present in buildings built or refurbished before 2000.
