How the survey works

The visit usually starts outside and finishes in the loft: first the slopes, edges and gutters from every safe viewpoint, then the loft space where it can be reached. In total, it takes about 1–2 hours for a house, though large, tall or awkward roofs take more time. Being in a smaller place like Nash Mills does not change how the visit works: outside, inside and from any safe vantage point, in that order. It helps to show us anything you’ve already noticed.

  1. First we discuss the roof, any damp and the forecast for the visit.
  2. We look over the roof from wherever it is safe.
  3. We take thermal images of the roof and of the loft where we can reach it.
  4. We take moisture readings where the images suggest a problem.
  5. Each image is set beside a normal photo and explained in the report.

Before we arrive

  • Gather any invoices or paperwork from past roof work
  • Have any questions written down, so nothing gets missed
  • If you are buying, check with the agent that we can get in

Arrange a survey

Thermal roof survey starts from £400, including VAT. What you pay depends on the roof’s size, access and the package, and you can ring 07833 053749 or use the contact form to find out.

Thermal roof survey in Nash Mills

Your report sets out the thermal images alongside ordinary photos, so it is easy to see which part of the roof each one shows. Each one comes with an explanation, the moisture readings and our recommendation. Premium reports are sent the same day. You can talk the findings through with us at the in-person consultation. There’s a 12-month follow-up as well. If you’ve noticed thin or uneven insulation in the roof and wet areas near outlets and upstands, a survey will tell you what’s going on, whatever the roof.

Around Nash Mills, plenty of roofs are low enough to see partly from the garden or the street. The parts you can’t see, like rear slopes, valleys and chimney tops, are where a drone or thermal camera adds detail. Both depend on the weather on the day, as calm, dry conditions suit both. Close-up images often show wear on ridges, verges and flashings that cannot be judged properly from the ground.

We write the report in plain English, so you do not need to be a roofer to follow it. Each point is backed by a photograph where possible, and recommendations are put with the most urgent first where relevant.

What affects the price in Nash Mills

Survey packages start from £150, with VAT included. The price for your roof depends on:

  • How complicated the roof is, with its valleys, chimneys and parapets
  • Building height and the viewpoints available
  • Whether it’s a home or a commercial building
  • The number of roofs, including extensions and garages

Prices start from £150, inc. VAT, for a Basic Survey. The Standard Survey starts from £250 and the Premium Survey from £400, both inc. VAT. We confirm the price for your survey before booking.

Getting in touch

We’ll usually ask about:

  • Your postcode, so we can check access and travel
  • How the loft is reached, if there is one
  • The style of property, from a terrace to a block
  • When you need the report by

Once you know what you need, call 07833 053749 or send us an email. From there it’s a case of choosing a package, agreeing the price and fixing a day.

Different roofs, different checks

Felt and asphalt flat roofs

Water under felt or asphalt can stay hidden for years. Thermal imaging helps suggest where it is, when the conditions allow.

Loft insulation

The difference is clearest when the home is heated and it’s cold out. We explain in the report how the conditions on the day affected what we saw.

Useful tips for Nash Mills property owners

There is plenty you can do without going near the roof. What helps most:

  • Do not switch the heating off before the visit
  • Check from the ground or a window, never by climbing
  • Check outlets after heavy rain
  • Ask us about the forecast if rain is expected

If the images suggest moisture that can’t be confirmed, we’ll say what would help next, like electronic leak detection or opening up a small area.

Watch for new damp patches on ceilings beneath the roof. Catching a leak early stops insulation getting soaked.

Why get it checked now?

Repeated repairs that don’t stop a leak are a sign the source hasn’t been traced. Combining the camera with moisture readings can help find it, rather than more guesswork. Around Nash Mills, leaves and moss in gutters lead to overflowing water and damp walls, particularly where trees overhang. Dealing with the cause is simple; drying out a wall is not.

Flying and imaging in Nash Mills

Where the drone is part of the survey, we check the Drone Safety Map for restrictions before flying. Historic houses such as High Elms Manor, about 3.1 miles south-east, show how far back building in the area around Nash Mills goes. Older roofs in the wider area can hide decades of patch repairs, so the detail matters, and any change of roofing material on a listed home needs checking with the council first.

Take an older house close to Church of St Mary: thin or patchy insulation under an old roof often shows up clearly on a thermal image. Anyone responsible for a site like Nash Mills Church of England Primary School will know that big roofs are where aerial photos and thermal images show the most at once.

Your questions about thermal roof surveys in Nash Mills

Is Nash Mills in the area you cover?

Yes, Nash Mills is within the area we cover. We survey roofs across London and the South East. You can phone 07833 053749 or drop us an email with the address and some details.

Will you come out to Nash Mills?

We do. Villages and rural addresses get the same survey as a town house.

Will you walk on the roof?

Only where it is safe to do so. We inspect what can safely be seen: from ground level, from windows and vantage points, from the roof space, from the roof itself where safe and by drone where it applies. The report says if anything couldn’t be seen.

What’s in the report?

A written report with photographs, explaining the condition of the roof, any defects and our recommendations. 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.

Can you give me structural calculations?

No. We’re experienced roof surveyors, and visible signs such as sagging are noted, but we don’t provide calculations or an engineer’s opinion. If one is needed, the report says so.

Do I have to be there for the survey?

Not necessarily. An outside-only look can be arranged beforehand, but the loft and any rooms with damp need someone to let us in.

Which days do you carry out surveys?

We survey seven days a week: weekdays, Saturdays and Sundays. Let us know which days suit you as you book.

What we can’t see

No survey can tell you everything, and it is better to know them up front. Keep these in mind:

  • Confirming water without moisture readings
  • Structural calculations, which need a structural engineer
  • Insulation values or heat loss calculations

If in doubt, phone 07833 053749 or use the contact form and we’ll point you to the right survey. The full list of what we check.
