Letchworth Garden City questions

Is Letchworth Garden City in the area you cover?

Yes, Letchworth Garden City is within the area we cover. We cover the whole of London and South East England. You can call 07833 053749 or use the contact form with the address and a few details, and we’ll talk through which survey suits.

Is my home in Letchworth Garden City listed or in a conservation area?

For listing, use Historic England’s list; for conservation areas, ask the council. It matters most if you’re planning to re-roof in a different material.

How long have you been surveying roofs?

We have completed more than 5,000 surveys, across 20+ years of surveying roofs.

I live in a flat. Can you survey the roof?

Yes, once whoever controls the roof agrees access. On a shared roof we can only inspect the parts we are allowed to reach, and the report makes that clear.

Can thermal imaging show missing insulation?

Thermal images can suggest where heat is escaping and where insulation may be missing. We do not give energy ratings or heat loss calculations, but the report shows where to look more closely.

Do you climb onto every roof?

Only when it’s safe. Most of what we need can be seen from safe viewpoints, the loft and, where applicable, a drone, and anything out of sight is recorded in the report.

What can thermal imaging tell me about my roof?

A thermal camera shows differences in surface temperature. Those patterns can point to trapped moisture, missing insulation or heat loss. We check what it shows with moisture readings.

Thermal roof survey in Letchworth Garden City: what you get

A thermal survey can point to places where heat is escaping through the roof. Gaps in loft insulation and poorly insulated areas can stand out on the images. The difference shows most clearly when it’s warm inside and cold outside. Our report points out what the images suggest and where to look more closely. It isn’t an energy rating or a heat loss calculation. Common reasons to book are ceilings that feel colder in places and damp where roofs meet walls and chimneys, on commercial roofs, insulated roof spaces and loft conversions.

Before any drone flight in a town like Letchworth Garden City, the airspace is checked on the Drone Safety Map, which shows restriction zones around airports and prisons. Our drone weighs under 250g, and we’re a CAA-registered drone operator (Flyer ID and Operator ID). We take care over neighbours’ privacy. In the open category, flights stay under 120 m (400 ft) with the drone in sight.

The Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where it applies, structural analysis and an in-person consultation.

Roof by roof

Parapets, valleys and junctions

Problems where roof slopes and walls meet are often hidden. A careful visual inspection goes alongside the images.

Loft insulation

Insulation frequently gets moved during work in the loft. The camera can show where it no longer covers the ceiling.

Thermal roof surveys around Letchworth Garden City

Older houses in the South East often have slate or clay tile roofs, while many later estates have concrete tiles, and flat-roofed additions turn up almost everywhere. A drone or thermal camera adds most on the steep, tall and hidden parts of roofs like these. Where the drone is part of the survey, we check the Drone Safety Map for restrictions before flying.

Hinxworth Place lies about 4.6 miles north, so building around Letchworth Garden City goes back a long way. For older roofs nearby, a look by drone or thermal camera is a hands-off way to check condition. The streets around a church such as St Michael are frequently among the oldest in a place, and if yours is one of the older homes nearby, steep roofs, tall chimneys and hidden valleys can be hard to see from ground level, and that’s where a view by drone or thermal camera helps. If you look after a building such as Pixmore Junior School, a drone or thermal camera can show a large roof in a single visit.

What this survey can’t tell you

Some things cannot be seen without opening up the roof, so a survey has limits:

  • The condition of timbers we can’t see
  • Clear results when the conditions on the day are poor
  • Insulation values or heat loss calculations

Not sure which survey suits your roof? You can phone 07833 053749 or use the contact form and we will tell you before booking. What a survey covers and does not.

  • When you need the report by

Letting agents often book on a landlord’s behalf, with the report sent to whoever needs it. We agree a time with the tenant beforehand.

Should I look at the roof myself first?

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.

After strong wind, take a look from the pavement or garden: pieces of tile or slate on the ground, a gap in the ridge or a lifted flashing are all worth noting. Do not go up yourself.

The survey, step by step

There isn’t much for you to do on the day. Show us any stains, drips or problem areas you know about, and we will take it from there. The survey itself takes about one to two hours at most homes, while a commercial roof takes nearer three to four hours. A visit in Letchworth Garden City runs most smoothly with the loft hatch clear, side gates open and a parking spot in mind. If you won’t be there yourself, let us know who will let us in.

  1. We go through the roof, the problem and the weather expected on the day.
  2. The roof is inspected visually from safe positions.
  3. Thermal images are taken across the roof and, where there is safe access, in the loft.
  4. Patterns that stand out are checked with moisture readings.
  5. Each image is set beside a normal photo and explained in the report.

Before the survey

  • Find any records of previous roof work
  • Keep pets out of the way during the survey
  • Jot down any questions you want answered

How to book

If you have photos of the roof, send them over. Take them safely from the ground or a window. To get started, ring 07833 053749 or email us.
