How a roof leak investigation works in Lagness

Moisture readings and thermal imaging are used where they’re useful. Moisture readings show which materials are wet. Thermal imaging shows temperature differences that can point to wet areas, not water itself, so we confirm what it suggests with moisture readings. Moisture detection is included in the Standard Survey, and thermal imaging in Premium. The best thermal results come after a sunny day, with a dry roof and little wind. We survey flat roof details, chimney stacks and slate and tile slopes, and people most often book us about drips from nail tips in a cold loft and leaks that appear only in driving rain.

Roofs in small places like Lagness frequently stand in the open, so storms hit ridges, verges and chimneys hard. Once water gets into older walls, it takes a long time to dry, which makes finding the cause quickly worthwhile. A record with photographs is useful if you need to show the damage to anyone else.

Every survey ends with a written report, with photographs, emailed to you. It sets out the condition of the leaking roof, any defects and our written recommendations.

Questions from Lagness

Does being near the coast affect roofs in Lagness?

Places near the sea get more wind and more salt in the air than inland, and both are hard on roofs. Salt corrodes metal fixings and flashings, and wind lifts loose slates, tiles and ridge pieces.

How do I find out if my home in Lagness is listed?

Check Historic England’s online list first, then ask the council about conservation areas and any Article 4 direction. The answer matters most when a change of material is on the cards.

How fast do I get the report?

Basic reports arrive within 48 hours, Standard reports in 24–48 hours and Premium reports on the same day. All of them come by email, ready to forward.

What’s in the report?

A written report with photos, covering the condition of the leaking roof, the defects we found and what we recommend, by urgency where it matters. 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.

Will you check the loft?

If there is a loft and safe access to it, yes. The loft space can show things the outside can’t, like damp timbers, staining or daylight.

Does the report include photographs?

Yes, plenty. Each finding is shown in a picture where possible, so you can see what we mean.

Which days do you carry out surveys?

We survey on any day from Monday to Sunday, during the day. Just say which days work for you.

What happens on the day

Photographs are taken throughout the visit, so you can see in the report what we found and where. Close-ups come from the safest viewpoint available, including by drone where it is applicable and the weather allows. Most surveys take about 1–2 hours for most homes, though a hard-to-trace leak can take longer. Somewhere as small as Lagness, access is often the only tricky part. Let us know about outbuildings, past repairs and any leaks you’ve noticed. Weekday and weekend visits are available.

  1. You pick a Basic, Standard or Premium Survey.
  2. We agree a date, including weekends.
  3. The investigation works from the stain back to the roof.
  4. Moisture detection and thermal imaging are used where your package includes them and they help.
  5. The report explains the likely entry point and what needs attention.

Preparing for the visit

  • Let us know about parking near the property
  • Tell us about any leaks, stains or damp patches you know of
  • Have any questions written down, so nothing gets missed

How the survey changes by roof type

Lead flashings

Wherever a roof meets a wall or stack, a flashing keeps rain out. We check for lead that has lifted, split or slipped, and for flashings that have been patched with bitumen.

Flat roof upstands and outlets

The upturned edge of a flat roof covering keeps water out at walls. If it is too low, cracked or poorly dressed, water gets behind it.

Tips from our surveys

Getting the most from a roof leak investigation starts before we arrive and carries on afterwards. Tips:

  • Mention earlier attempts to fix the leak
  • Protect furniture and flooring under the leak
  • Move stored items away from the hatch
  • Photograph the stain each time it appears

Once the work is done, hold on to the report. If the leak returns, it’s a useful record of what was found.

Don’t block the vents at the eaves. Air movement keeps condensation down, which is frequently mistaken for a leak. Make sure insulation does not block airflow at the eaves.

Why act early in Lagness

A leak near lights or wiring needs attention quickly. If water is reaching a light fitting or switch, keep clear of it. Finding where the water is getting in should follow right away. Older cottages and farmhouses around Lagness can have roof timbers that have been there a very long time, where water from a failed roof can cause rot if it’s left.

One thing that affects the price is the package: from £150 for Basic, £250 for Standard and £400 for Premium, with VAT included. The roof’s size, height and access matter as well.

Why book us in Lagness

  • We hold a CAA Flyer ID and Operator ID
  • Thermal imaging and drone inspection where they help
  • An independent look at the roof
  • Satisfaction rate of 98%

Wind, rain and roofs in Lagness

Lagness lies within about 3 miles of the sea, so there’s more wind and more salt in the air than further inland. Wind lifts loose slates, tiles and ridge pieces, and driving rain finds any gap they leave. Handmade clay tiles and tile-hung upper walls are typical of older Sussex houses. A few old Sussex buildings still carry heavy Horsham stone slabs. Different coverings let water in at different points, which shapes where the search starts.

Goodwood House lies about 4.9 miles north, so building around Lagness goes back a long way. Leaks in period homes nearby often come from lead work and valleys that have been patched before. Take an older house close to Church of St Giles: water on an older roof tends to find its way in at the lead, the valleys or the chimney. Living close to Avisford is pleasant, but mature trees mean leaves in gutters and valleys each autumn.

Can I check my roof myself?

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

What you cannot do safely is get up close. Slates, tiles, flat roofs and rooflights can give way, and falls from height are serious. That is where a survey comes in, using safe viewpoints and a drone where applicable.
