About our thermal roof survey in Merrow

Wet insulation under a flat roof covering holds heat for longer than dry. That means a wet area can show up as a different temperature from the rest of the roof. It helps us see how far water may have spread under the covering, which is hard to judge by eye. Moisture readings are then used to check what the camera suggests. Typical surveys look at patches of heat loss across the roof and possible trapped moisture under a flat roof covering, across loft conversions, insulated roof spaces and flat roofs.

Around Merrow, older homes can have thin loft insulation and later additions with roofs of their own. Thermal patterns and close-up photos together give a fuller picture of the roof. Anything that looks like moisture is checked with a meter. Calm, dry weather suits both methods, so the date is set with the forecast in mind.

Most points in the report come with a picture, so you can see each defect rather than just read about it. Anything out of sight on the day is listed as such.

Merrow: your questions answered

Is Merrow in the area you cover?

Yes, Merrow is one of the places we work. The survey and report are the same in Merrow as anywhere else.

Do you cover smaller places like Merrow?

Yes, we do. Our area covers London and the South East, from towns to the smallest villages. Longer journeys are simply planned in advance.

How much does a thermal roof survey cost?

Our Premium Survey, from £400, includes thermal imaging. You also get an in-person consultation and a 12-month follow-up. For bigger commercial roofs, we quote on size.

Can you give me structural calculations?

No. We point out what can be seen, like 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.

What will the report tell me?

It works through the roof part by part, in writing and with photos, and ends with what we recommend. The most urgent items are made clear.

Does thermal imaging work on slate and tile roofs?

On pitched roofs, the camera can point to heat loss and some damp patterns. Our report is clear about what can be read from them, and we check them with a visual inspection and moisture readings.

Are you insured?

Our cover is professional indemnity plus public liability, and we can provide details if a managing agent needs them.

Thermal roof surveys in Merrow: local notes

Clandon Park, about 0.9 miles east, is one of the historic houses in the wider area around Merrow. On older houses around here, roofs frequently carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first. Many older homes in Surrey have handmade clay tiles and tile-hung upper walls. Some old buildings in Surrey and Sussex have Horsham stone slab roofs. Steep or complicated roofs are often hard to see from ground level, which is where close-up aerial shots and thermal images help.

Take a building like Bushy Hill Junior School: a drone or thermal camera can show a large roof in a single visit. For an older house near a landmark like Church of St John the Evangelist, steep roofs, tall chimneys and hidden valleys can be hard to see from the ground, and that is where a view from above or with a thermal imager helps.

Leave it or get it looked at?

A poorly insulated roof loses heat year after year. The camera can point to gaps and thin areas in the insulation, so you know where to put things right. Tradespeople may need to travel further to a smaller place like Merrow, so it helps to plan roof work rather than call someone out in a hurry. Knowing early gives you time to get the right people in.

To find out what your survey will cost, phone 07833 053749 or send us an email and tell us about the roof. We will confirm the figure before booking.

For landlords and managing agents

Letting agents can arrange access with tenants. We survey on weekdays and at weekends, which helps when tenants work during the week.

If you own several properties, surveys can be booked for more than one address. To discuss a number of properties, phone 07833 053749 or email us.

Can I check my roof myself?

You can learn a lot from the ground. Binoculars help you spot slipped slates or tiles, gaps along the ridge and a leaning stack. Never climb onto the roof to look.

Keep a simple record: when leaks happen, ground-level photos and any past roof work. Send it with your enquiry.

What happens on the day

The visit usually starts outside and finishes in the loft: outside views come first, then the roof space if there is safe access. In total, it takes an hour or two for most homes, plus time to check any thermal findings with moisture readings. For a survey in Merrow, we agree the time, the access and parking before the day. Weekday and weekend visits are both possible. If there are outbuildings or garages you want looked at, mention them.

  1. We start by discussing the roof, any signs of damp and how the weather may affect the images.
  2. The roof is inspected visually from safe viewpoints.
  3. A thermal camera records how the surface temperature varies across the roof.
  4. Areas that look unusual on the camera are checked with moisture readings where possible.
  5. We write up the thermal images alongside ordinary photos and recommendations.

Preparing for the visit

  • Tell us about parking before the day
  • If you’re buying, check with the agent that we can get in
  • Gather any invoices or paperwork from past roof work

Advice

What this survey cannot tell you

A survey is a careful look at the roof, but it can’t do everything. The main limits are:

  • Insulation values or heat loss calculations
  • Reliable images in rain, strong wind or on a wet roof surface
  • What’s inside walls or under coverings, without opening up

If you’re not sure which survey you need, phone 07833 053749 or send us an email and we’ll give you a straight answer. What a survey covers and does not.
